may be turned back on when road
conditions allow. TCS and StabiliTrak/ESC will
automatically turn on when cruise control
is set.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See If the
Vehicle Is Stuck 0 198 and Turning the
Systems Off and On later in this section.
The indicator light for both systems is in the
instrument cluster. This light:
Will flash when TCS is limiting wheel spin
Will flash when StabiliTrak/ESC is
activated
Will turn on and stay on when either
system is not working
May flash when ABS is active
If either system fails to turn on or to
activate, a message may display 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.
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.
