What is VSC and TRAC

i just picked up my new taco! 2010 access cab 4WD 2.7.

i'm wondering... can anyone tell me what VSC and TRAC are and when one might use them?

 

VSC = Vehicle Stability Control. This general butt-saver looks at yaw rates, steering angle and throttle inputs to keep you pointed straight through selective brake use.

TRAC = Traction Control. This prevents your drive wheels from being over-powered and spinning.

Both systems are VERY handy for street driving, especially in less than ideal conditions.

 

can you expand on that? how is it used for street driving?
after reading the manual, i was under the impression that they are only to be used in 4Low.

thanks for your comments!

 

Ive always wondered about this too. The owners Manual doesnt explain it very well in my opinion.

 

Street, in this context, just means normal driving on public roads. There is lots of discussion around here about off-roading, and I was just adding that for clarification.

Both of these systems are on full-time in 2Hi and 4Hi, except when you choose to disable them using the button to the low left of the steering wheel to disable them. 4-Lo automatically disables both of these assistants, perhaps under the assumption that you are off-road.

When driving on ice, if you use too much power, you will overcome the available traction of the tires and they will spin. TRAC prevents this. Once spinning, it is likely that the rear of your truck will start to go sideways. VSC prevents this slip (or drift) from becoming excessive and will correct it for you.

 

from another thread; just more details...

 

when should you use auto LSD?
