Driving
TRACTION CONTROL (IF EQUIPPED)
Your vehicle may be equipped with a traction control system which helps
you maintain stability and steerability, especially on slippery road
surfaces such as snow- or ice-covered roads and gravel roads, by
reducing engine power and/or selectively applying the rear brakes.
Note: The traction control system does not apply the brakes when
vehicle speed is above 25 mph (40 km/h).
When the traction control switch is
pressed, standard traction control
changes to Off Road or Mud/Snow
traction mode and the traction
control light illuminates and flashes
slowly. If a traction event occurs, in
either mode, the light flashes
rapidly. The standard traction
control can be selected by pressing
the traction control switch again or
is automatically selected at next
ignition cycle.
During traction control operation,
the traction control light flashes
rapidly and the engine does not
"rev-up" when you press further on
the accelerator; this is normal
system behavior and should be no
reason for concern. If the traction
control light does not flash during a
traction control event or stays illuminated, the system is not functioning
properly, take your vehicle to your dealer for service.
If you should become stuck in snow or ice or on a very slippery road
surface, try switching to the Off Road or Mud/Snow mode. This may
allow excess wheel spin to "dig" the vehicle out and enable a successful
"rocking" maneuver.
WARNING: Aggressive driving in any road conditions can cause
you to lose control of your vehicle increasing the risk of severe
personal injury or property damage. The occurrence of a traction
control event is an indication that at least some of the tires have
exceeded their ability to grip the road; this may lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death. If you experience a severe road event, SLOW DOWN.
