system. These systems help limit wheel slip
and assist the driver in maintaining control,
especially on slippery road conditions.
TCS activates if it senses that any of the
drive wheels are spinning or beginning to
lose traction. When this happens, TCS
applies the brakes to the spinning wheels
and reduces engine power to limit
wheel spin.
StabiliTrak/ESC activates when the vehicle
senses a difference between the intended
path and the direction the vehicle is actually
traveling. StabiliTrak/ESC selectively applies
braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping
the vehicle on the intended path.
If cruise control is being used and TCS or
StabiliTrak/ESC 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 0 194 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/ESC 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
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
on, the vehicle may need more time to
diagnose the problem. If the condition
persists, see your dealer.
Turning the Systems Off and On
(Uplevel Cluster)
Do not repeatedly brake or accelerate
heavily when TCS is off. The vehicle
driveline could be damaged.
At speeds of 56 km/h (35 mph) or above,
this ability to turn off or on is disabled.
