Winter - Stability Control scare

Fair enough, but applying the brakes suddenly to the car, in pure ice conditions, is a catastrophe.
Traction control and stability control don't apply the brakes hard or all that suddenly. It's pretty progressive, not an on/off thing.
A car should never suddenly or urgently apply brakes to a car in poor conditions, as this will upset the car's balance.
True, but it's not sudden or urgent with traction control or stability control in this car. The problem was your tires did not suit the conditions at all. It does not take sudden or overly firm applications of throttle or brakes to compromise traction on ice or snow with the stock tires. Try your little experiment again later in the winter with proper tires, and notice the difference in how well the TCS works.
ECS didn't know what to do in both cases, and nearly caused an accident in both cases.
Prove this statement. Demonstrate to me that you could have controlled the vehicle with summer tires on better than the TCS/DSC system could have. I am incredibly skeptical. You are attributing the cause of your problems to a computer system you don't understand and don't trust rather than the more obvious problem - summer tires on snow an ice.
However, no system should ever be a danger to the driver when it equipped on the car, regardless of what kind of tires he or she has.
Are you kidding me? You were running summer rubber in a winter storm, you lost control, and you think it was the TCS/DSC that was causing you problems? Uh....
Enjoy the ditch. I'll wave to you while I pass by. Obviously I'm posting in vain here. Clearly no one lives in a real cold weather climate.
That's kind of a broad (silly) assumption to make. I also live in Canada, and my experience with driving in snow and ice is at least as extensive as yours. I just don't feel that getting into a "I HAVE A BIGGER SNOW DRIVING EXPERIENCE E-PENIS" pissing contest with you is particularly relevant (also speaking to authority is a logical fallacy but I digress).

Conditions are not consistent everywhere you go.
No, they aren't, but you can account for that by driving conservatively based on the conditions outside. Where as if you intentionally lose traction you are putting yourself in a very real and very precarious situation where you might not be able to get it back. And then maybe you'll be sitting in a ditch telling the police "I just sort of e-braked a little to test how slippery it was" while a tow truck hauls your little car out of a situation you intentionally put it in as an experiment.
If you so much as lane change without knowing if the middle line is slicker that the lanes, you'll end up backwards. You have to pay attention to subtle things, like which direction the torque steers the car - that tells you under which wheel there is the most ice buildup, the dynamics how the traction returns, how loose the steering play is.
Yes yes, these are all things experience teaches you, same with winter driving courses, etc.
I'm not talking about full on floor brake traction testing - slight tap on the brake pedal. If the car slows down, you know you're good. If the car juts sideways, you konw you're in a world of s***.
Don't you sort of get to do this during most of your driving? You know, at stop signs and stop lights and railway crossings and, oh, I don't know, pulling out of your driveway? Plus, shouldn't all your experience and knowledge about winter driving have taught you (by now) that it is better to drive with enough caution to give you a margin of error with your grip? Plus, that you shouldn't be running performance summer tires in snow and then blaming your handling issues on some computer nannies when the error was quite obviously the person behind the wheel that did not put the correct rubber on his vehicle for the conditions?
I've avoid several rear end accidents by demonstrating to the people behind me that it is in fact not safe to be following as close as they are. A slight tap, cocks the car a bit, the guy behind me would back waaayyy off.
Oh, you're that guy. The brake checker. Makes sense.
Hey that might be you next time!
Unlikely.
"Driving to conditions" changes ever foot, every inch, especially when the temperature hovers at the just-below-freezing mark. Contaminated water won't quite freeze, giving the illusion of just wet road. However there may be patches of "black ice" that only gives its location away by a slight sheen on the road. This could be mistaken for wetness, and judging by the number of people on their roof on the side of the road every year, it clearly is.
Knowing this, one might think it is better to simply drive cautiously enough so that you are never so close to the edge of grip on one surface that changing to another compromises your ability to drive. One might be able to, with enough experience, derive feedback from their vehicle that alert them to changing conditions that do not require random brake tests or swerving on snow and ice. One might understand that driving to conditions means understanding how conditions change, how the car will respond to those changing conditions, and being able to recognize those conditions without actively placing the vehicle in a situation where grip is compromised. Maybe.
Perhaps some foresight on these people's behalf could have prevented such single vehicle accidents - maybe "checking" how slippery it is before being forced into an emergency situation.
Foresight like driving to conditions?
Maybe I should write a book on bad weather driving. Clearly some people need education.
Yes, they do. But not from you. Please don't encourage people to brake check and swerve on snow and ice to constantly re-evaluate conditions. They should just take a winter driving course from someone who knows what they are talking about (not you). I'm not saying you can't drive in the winter, I'm saying that your entire approach is pretty daft. You do not, in slippery and icy conditions, actively cause a skid in the car, especially on summer tires, and then act surprised when control is compromised. You do not b**** about TCS/DSC when you put it in a situation where it has insufficient grip to do its work. Also maybe read the manual about it, it's pretty helpful.
Both agree ESC created a dangerous situation from normal driving.
I am VERY happy that the countless years of combined experiences from various safety institutes, car manufacturers, researchers, statisticians, engineers and emergency services strongly disagree with the opinion of two guys on the internet who are stupid enough to run summer rubber in winter conditions and then b**** about the consequences.
Drive safe!
Well at least we can agree on that.

I am going to repeat this because it is worth repeating. Make sure you have appropriate rubber on your car for the conditions. Make sure you understand what the TCS/DSC is going to try to do when it activates. Understand your limits as a driver. Take a course about winter traction. Consider how your actions affect drivers around you. Drive safe. These are things you need to do in the winter.

An experienced winter driver does not need to actively experiment with the conditions on the road. They drive with enough caution and enough focus in adverse conditions that they are both aware of the conditions (as they change) and aware that they have enough of a margin of safety (space, time to react, grip, etc) that they can properly react to conditions on the road. Actively compromising traction actively puts your vehicle in a situation where you just might not be able to correct it. A good driver learns how to handle their vehicle in adverse conditions, learns how to drive conservatively for conditions, and learns how to get enough feedback from merely driving that you don't need to look for situations to "test conditions". And when a good driver ***** up (IE: does not put the right rubber on their car) they suck it up and admit it, like a man. They don't look for something around them to blame.

The MS3 is quite simply the easiest vehicle to drive in the winter I've ever owned, and this is coming from someone who has driven a Civic, a minivan, a RWD pickup, an '88 Ford Bronco, and a Lada in ice and snow. Ottawa had the worst winter it has seen in 30 years last year, and this car AND its nannies handled it beautifully, in part because I was running good tires and in part because the TCS/DSC systems when combined with a tire that will actually provide grip work wonderfully on ice, and throttle is easy to modulate when you've turned them off to try and claw out of deep snow. What you did was put the car and its safety systems into a compromised situation on tires incredibly unsuited to conditions, and you're surprised those safety systems didn't just magically find grip in a situation where there was basically none (stock summer rubber on ice and snow). You're also surprised that brakes were applied without you applying them after you intentionally induced a skid. You need to learn how these systems work before you start spouting off to people about them.

+9871283761.. Although not a 4x4 I've driven with snow shoes, the Speed was quite an enjoyable driving experience in the harsh winter (I'm from the other side of the river btw..(canada) ) we had last year. Everything was predictable in this car. It's just a different ball game with tires not meant for the appropriate weather conditions..

You are not very Happy today!

To be honest, my old car drove better in the snow, but I think it was because it was heavier and had higher profile tires, I believe they were 205, 70, 16 inch on a Pontiac Grand Prix vs the MS3 215, 45, 18. The point is tires are probably the single most important factor in winter driving besides the driver. I am sure a 16 year old could wreck any car in the snow, even when equipped with tires with studs!
 
Holy.... Wow.... Well, I dont know about anyone else but I already have my all seasons on. Oct. hits and on they go. I drove in one storm last year with the summers still on. You can get the car to move but it WILL NOT stop.
 
snow? ice?

i dont have much experience at all. zero with this car. with my 4x4 trucks, which means craap on ice and snow, i just use the simple rule. go slow, no sudden actions, and anticipate everything.

never heard of gasing or brakeing to test traction. i dont live in canada either. so dumb question. wont gasing give you the same indication as braking? i mean traction is exactly the same either way. hell, in engineering braking is just negative acceleration. why do you need to do both?
 
You are not very Happy today!
I'm very happy! I just really don't like the sort of misleading misinformation that was getting tossed around here, because it might lead someone out there to approach winter driving in an unsafe manner and get them (OR MORE IMPORTANTLY THEIR PRECIOUS PRECIOUS SPEED3) hurt.

Oh, and yea, the profile of the tire hurts us a bit, as does tire width and contact patch. A taller tire can flex more to contour better to broken pavement or broken ice on the road, and a narrower tire allows you to put more weight on a smaller contact patch which can help get the tire down throw heavy or packed snow to the stable base where you are more likely to find traction. You can "hydroplane" on snow, and a wider tire makes that easier.

When I said the 'speed3 was fantastic in the snow, I meant that it is well balanced and predictable when you do lose grip in the front, easy to catch and correct when the back end gets out, and the TCS can really help with stop and go stuff on icy roads. A big part of that was the Blizzak WS-60's I run (greaaat winter tire), but I was impressed with how well composed it was considering how low and rigid it is and how much power it has.
 
Well oddly enough I live in Regina too and had no issues driving, my car. I had no issues driving the car in this weather, I was driving around the whole weekend and, not once did I need to test the traction control, nor did my car experience any of the stuff you mentioned in the first post, it more or less was just slushy snow, the temp was not cold enough to harden the tires to a point where they were completely useless, they definitely had less grip, but nothing compared to when I had the car with the stockers in the middle of december.

This is my first car with any traction/stability aids and let me tell yah they are great when paired up with the appropriate tires, simple as that.

I will admit only one winter with this car and it is the best winter car I have ever driven.
 
I too grew up driving in the worst of winter conditions (read: not totally frozen and not usually thawed... that dangerous wet ice in-between stuff that you get across northern michigan, wisconsin, ontario, etc).

A good winter driver DEFINITELY tests the traction constantly. And by test we're not talking about swerving or slamming on the brakes or flooring the throttle. We're talking about finding the limit of traction in any direction and then backing off... The car needn't even leave its path or lift its ass in the air. All you need is to feel how good the grip is.

I'm not saying we should all drive like Sebastien Loeb but if you ever watch world rally championship racing, you'll see them constantly checking traction with little twitches of the steering wheel. That feeds them back a continuous flow of realtime information about the surface they are driving on.

Now as for the issue encountered by the OP, it was definitely a result of the stock tires. All these traction and stability control systems on cars are designed to work within some general parameters... a certain minimal amount of grip. Trying to run summer tires on glare ice means you are asking the system to perform well outside of its range of capability. With allseason or better yet, winter tires on, it would certainly do much better, as has been attested by everybody else in this thread.

The same thing happens with ABS in certain conditions. If you catch it just right, you can sometimes lock up all 4 wheels at once and trick a car's computer into thinking it has stopped... and thus the car ABS controller does not intervene and reduce braking pressure. Similarly, operating a DSC well out of its normal parameters can result in similar unexpected behavior. Seeing as how vehicle dynamics is one of the most difficult aspects of automobile design, I think the least you can do is operate the thing as intended.

Quit being a putz, put your winter tires on, and enjoy the car. s***. RE050A's in late fall Saskatchewan. What were you thinking?
 
I have absolutely no experience in driving in the snow, hell I hadn't seen the stuff in person until 2006 when I went on vacations to the province of Quebec (gorgeous place btw, I want to go there again). But I can relate a bit to what people are talking about "testing" the surface for grip. Over here there's usually sand on the road, and if you add to that fine surface of sand some water from an old water main that burst, things can get pretty interesting. On the previous car I had without TC/DSC I used to spin the tires a bit from a dead stop in order to clean the mud off them, but a little spin is all that is nessesary, and with the MS3's grip it has been unnecessary so far.

The only time DSC has engaged is on an ocassion I took a corner too fast and there was a fine layer of water in the middle of it, the car snapped sideways and altough I managed to countersteer and remove opposite lock on time, I'm still pretty sure DSC saved my ass. The reason I'm not 100% sure it saved my ass is that I was looking towards where I wanted to go, not at the instrument panel and not into what I was going to crash, and that's the main problem I have with what the OP says. It's stated someting along the lines of "I gave up and closed my eyes", and I'm of the idea that if you are driving and run into a problem, you should keep diving, and you MUST keep staring at where you want to go. It sounds obviously simple, but hand-eye coordination can have more influence that what one might think it has.

I hope I'm making sense...
 
I've been driving in heavy snowfall saskatchewan winters (5-6 months of knee deep snow and -30 C conditions), cutting my teeth with my first driving experiences at 14 in the middle of january. I have been driving day in day out for over 11 years since I got my license. I have never been at fault in an accident, of which I've only been in one, which was one lady who decided to drive into me with her RAV4 in gridlock.

I know what I'm doing.

And not testing your traction in icy conditions is like driving blindfolded. If you could be doing 30 mph safely on one road, while another one might only be safe at 10 mph. Anyone not testing their traction clearly has never driven in extremely poor conditions - I've passed countless cars in the ditch from people going 60 mph in unsafe conditions, only realizing they are going too fast when they fly off the road.

Anyways, I didn't expect to be giving winter driving lessons, my point is that ECS can get confused very easily, and with winter coming I wanted to let people know to be careful - you might think you're controlling your vehicle in an emergency or sudden ice situation, when the computers might be taking it from you.

And yes this was on stock tires - but thats irrelevant. I have winters in my shed - but I knew it was going to go back to warm weather immediately after, so no sense switch out rims for 24 hours of driving. I was midly curious to see how the Potenzas and TCS would deal with non-ideal conditions. I was surprised how well the car could go (probably due to the limited slip diff) but I was equally surpised at how poorly it could stop. Literally football field lengths from 10 mph.

I certainly wouldnt recommended this experiment to anyone with poor conditions driving experience. But I knew what I was getting into. Just didn't expect the ESC to try and kill me.

From past experience the fact that you were on the stock (summer only) tires were a major part of the issue. As a side note, I"ve driven Alberta winters for 23 years...so, snow ice, black ice rain you name it. I once took my old sentra se-r spec v out for a brief spin in regular snow (no ice buildup but packed down some)...I went as far as 5 houses before I gently applied the brakes at 20km/hr..and went totally sideways instantly. The electronic nannies in the speed 3 saved your car, since you didn't think it necessary to change over to winter tires at the time.
They cannot be totally disabled btw, but can be dialed back some via the one button. I don't care how much of a veteran driver you are, driving with summer only tires in winter is a huge no no. Thank goodness you didn't do any damage to your car or any one else's. I recall more than one story from the old nissan boards of people driving their cars over curbs and into parked vehicles since they didn't think the 'warning' summer tires only bit applied to them.

laters,

Take note of the final article. Thats the last I'm going to argue with anyone about winter driving techniques. Also, to Happy and Angry who said I was a "brake checker"??? Please stop taking everything I wrote GREATLY out of context, and please read the "Use Defensive Braking" article. In fact I think this whole article would help you out. Everything I mentioned is in there somewhere, so you should probably go after CanadianDriver for "Encouraging people to brake check and swerve on snow and ice to constantly re-evaluate conditions."

Now where's that "SOMEONE IS WRONG ON THE INTERNET" avatar? It needs to be posted.

I am VERY happy that the countless years of combined experiences from various safety institutes, car manufacturers, researchers, statisticians, engineers and emergency services strongly disagree with the opinion of two guys on the internet who are stupid enough to run summer rubber in winter conditions and then b**** about the consequences.

I am too. I'm just trying to warn people of a danger. This is me trying to help. And, in the tradition of taking things I say out of context, I never bitched about the consequences of using summer rubber in winter. I was bitching about DSC operating erratically and illogically. DSC will probably save a lot of SUV drivers from rolling over on their roof, no argument there. Just like how ABS will allow people to steer when their foot is stomped on the brake pedal. However without the proper parameters provided to it, it needs to be defeated.


All these traction and stability control systems on cars are designed to work within some general parameters... a certain minimal amount of grip. Trying to run summer tires on glare ice means you are asking the system to perform well outside of its range of capability

Thats an explanation. I'll keep the system turned off if I get caught up in another freak snowstorm like that. For winter proper I'll have snow tires and I'll see if there is any computer shenanigans. For what its worth, I've done some water cooler talk around here with work colleagues and they all agree - the guys anyway - that it has made a bad situation worse instead of correcting it, probably because it was never designed for arctic winter wasteland.

Hey to the posters from Ontario; what are you guys doing to protect your MS3's from salt damage? They don't use the stuff here.
 
For what its worth, I've done some water cooler talk around here with work colleagues and they all agree - the guys anyway - that it has made a bad situation worse instead of correcting it,
All due respect, asking a couple guys around work is about as useless as asking a third grader.

The average guy doesn't possess the most basic understanding of how vehicles make it from point A to point B, let alone understanding the very fine intricacies of vehicle dynamics.

Even car guys are typically clueless on this topic so all you'll get is a bunch of opinions that amount to your basic grunts and scratches from a caveman. Ugh! Me make fire! Me drive car! TSC is for pussies!

The TSC actually works quite well! It allows some slip, lets the car drag along without bogging. I'm also pretty confident that some dudes around a water cooler are the scientific experts in all fields. But seriously, there are some conditions here that you actually need to slide a little bit. Giant ruts for instance - your tires are going to be those grooves even if it means your yaw is off kilter, and you can't stop in an interstection like that. You have to slide through it if you have to. If DSC tries to stop you in those giant ruts, its going to take a tow truck to get you out. So I still don't buy all this DSC defense, and I never will.

But, again this isnt a DSC: Better without it? thread. This is a - hey man watch out - thread.
 
have you ever driven any non-DSC equipped cars with summer only tires in similar conditions and taken a similar action to see how the car reacted?
 
Go Canada. I'm with LukeP on the testing. It's hard to tell if the shine on the road is either ice or just glare from the sun. When I start driving in the winter, I usually give it a bit of gas of the start to establish the traction limits of acceleration, which is what LukeP said, then do the same with braking, it gives you a great starting point, but always driving with caution is the best bet.

And with driving with summer tires on, it can be done. Definitely not recommended, but again, just use caution. I love people that drive like they do in the summer for the first snow fall. Hilarious amount of accidents.

Where in Sask you from LukeP? I have family near Kindersley.
