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 Centre (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.
4. 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.
