Ride Control Systems
Traction Control/Electronic
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
wh
eel brakes to assist the driver in keeping the
vehicle on the intended path.
If cruise control is being used and the traction
or stability control system begins to limit
wheel spin, cruise control will disengage. 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178 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
•
Will flash when the StabiliTrak/Electronic
Stability Control system 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, and d 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 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, the vehicle may
need more time to diagnose the problem. If the
condition persists, see your dealer.
