If this message comes on and stays on or comes on
while you are driving, there's a problem with your
traction control system.
See "Service Traction System Warning Message" in
the Index. When this warning message is on, the
TRAC OFF light will come on to remind you that
the system will not limit wheel spin. Adjust your
driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to.
