The indicator light for both systems
is in the instrument cluster. This
light will:
Flash when TCS is limiting
wheel spin.
Flash when StabiliTrak is
activated.
Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC),
and comes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If comes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait
15 seconds.
3. Start the engine.
Drive the vehicle. If comes on
and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.
