Stability Control
The vehicle has aTraction Control System
and aStabiliTrak/Electronic Stability Control
system. These systems help limit wheel spin
and assist the driver in maintaining control,
especially on slippery road conditions. Both
systems come on automatically when the
vehicle is started and begins to move.
The Traction Control System activates if it
senses that any of the drive wheels are
spinning or beginning to lose traction. When
this happens, the traction system applies the
brakes to the spinning wheels and reduces
engine power to limit wheel spin.
The StabiliTrak/Electronic Stability Control
system activates when the vehicle senses
adifference between the intended path and
the direction the vehicle is actually traveling.
The stability control system selectively applies
braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping the
vehicle on the intended path.
Cruise control will disengage if the traction
sy
stem or stability control system begins to
limit wheel spin. Cruise control may be turned
back on when road conditions allow.
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 the Traction Control System
off if the vehicle gets stuck in sand, mud, ice,
or snow. See If the Vehicle Is Stuck 3160 and
“Turning the Systems Off and On” later in
this section.
The indicator light for both systems is in the
in
strument cluster. This light will:
•
Flash when the Traction Control System is
limiting wheel spin.
•
Flash when the StabiliTrak/Electronic
Stability Control system is activated.
•
Tu
rn on and stay on when either system is
not working. See Traction Control System
(TCS)/Electronic Stability Control Light
398.
If either system fails to turn on or to activate,
amessage displays in the Driver Information
Center, and d comes on and stays on to
indicate that the system is inactive and is not
assisting the driver in maintaining control.
Adjust driving accordingly.
If d 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 d comes on and stays on, see your dealer as
soon as possible.
