How do i drive up a hill in snow with traction control on ? my engine almost shuts down

That's normal operation for automatic traction control.

that is your traction control system known as (TCS) ,,it is simply used for when you are driving up hills or in snow ,,also wet roads ..I never really seen the need for this ,,but they put them in vehicles

Have it checked for DTC'S - diagnostic trouble code's.

All vehicles will slide in the snow. Traction control or not. What traction control does, in simple terms...Is when your wheel start to slip, which is detected by some sensors, it lowers the vehicles throttle position, slows the RPM's down, even if your foot is still on the gas, for a matter of seconds, until the wheels stop slipping. So when you feel or hear your vehicles engine slowing down on its own, its best to just let off the gas and let it go for a couple seconds. A way to test the traction control...From a stop, if you are in the snow, and you push the gas down a good bit, make it spin, and the vehicle should seem to power down on its own, while the light comes on, if it does not do this, then traction control would not be working. Hope this helped.

Hi Correia,
Having four wheel drive built onto a vehicle gives traction through all four wheels, meaning that if one of the four wheels looses traction all the driving motion is directed through that spinning wheel. When driving on snow, ice or mud, gently does it all the time! Gentle acceleration and slow down using gentle gear changes. Use the brakes as little as possible. Remember if you lock up the brakes and the vehicle begins to slide you'll have no control at all! Traction control is entirely different than four wheel drive. Traction control will control any wheel which begins to slip and thereby keep you in control.

Don't turn off traction control - it helps the car maintain traction.
A 350Z isn't a car that should be driven in the snow.
If you are rolling down a hill you have other issues.
Does it roll back if it's on dry pavement?

And remember snow makes tires slip.

With all due respect, what the H___ are you doing driving in 2 Feet of SNOW? The rumbling noise you hear is most likely caused from Snow being impacted in the CV Joints, Wheel Wells and anywhere else from freezing in place after driving in the "Deep Snow". The solution is to have the care raised on a Hoist and Pressure Washed to remove all Snow and Ice from the the entire Bottom Side of the Vehicle. It then should be allowed to dry thoroughly in that building before being driven. Additionally, if any noises occur upon exiting that facility turn around and have it repaired before it costs you untold thousands of dollars to repair.

Next time you have "DEEP SNOW" wait until the Roads have been cleared, salted or sanded and are back down to pavement before driving on them.

no theres a problem with the abs, when abs doesnt work it turns on both those lights, you have to have computer scaned to get codes to diagnose the problem, it maybe just a wheel sensor. you cant turn it on or off, but you can still drive like that you just wont have abs trac-control when lights on computer shuts it down, so its like you shut it off, if you dont need it then dont fix it,wont affect running of engine .good luck.

Traction control systems measure wheel speed differences by various methods to determine if one wheel is rotating faster than the other. A heavier buildup of ice/snow could be affecting wheel rotation speed causing the TCS to engage. ABS works by sensing slippage at the wheels during braking, and continually adjusting braking pressure to ensure maximum contact between the tires and the road. Suggest clearing out the wheel wells now and periodically throughout the winter. Also remove ice/snow build up between the wheel and the brake pads/rotor.

Are the new tires rated for ice & snow? They are a softer compound & grip better in cold weather.
