240 DRIVING AND OPERATING
If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road conditions
allow.
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 0 212 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
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.
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.
Turning the Systems Off and On
Caution
Do not repeatedly brake or
accelerate heavily when TCS is off.
The vehicle driveline could be
damaged.
