The Traction Control™ system will allow your vehicle to make better use
of available traction on slippery surfaces while you are trying to
accelerate or while your foot is on the accelerator pedal. The system is a
driver aid which makes your vehicle easier to handle primarily on snow
and ice covered roads.
During Traction Control™ operation,
the traction control active light will
illuminate. If your vehicle is
equipped with a message center, a
message will display during Traction
Control™ operation. You may hear
an electric motor type of sound coming from the engine compartment
and the engine will not “rev-up” when you push further on the
accelerator. This is normal system behavior and should be no reason for
concern.
The Traction Control™ switch,
located above the radio, illuminates
when the system is off. The Traction
Control™ system will automatically
turn on every time the ignition is
turned off and on.
If you should become stuck in snow
or ice or on a very slippery road
surface, try switching the Traction
Control™ system off. This may allow excess wheel spin to “dig” the
vehicle out and enable a successful “rocking” maneuver.
The traction control on/off status is shown by an indicator lamp on the
traction control switch. If the system is off, the indicator will be
illuminated. If a system fault is detected, the traction control active light
will illuminate, the Traction Control™ button will also illuminate and will
not turn the system on or off and your vehicle should be serviced by an
authorized dealer.
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.
