into four-wheel drive mode (if equipped), the traction control system will
be automatically disabled. Traction control operation will resume when
the vehicle is placed back into two-wheel drive mode.
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.
The Traction Control™ switch,
located on the instrument panel to
the left of the climate control
system, has an indicator light that
illuminates when the system is off.
The Traction Control™ system will
automatically turn on every time the
ignition is turned off and on. The
Traction Control™ system should normally be left 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.
If a system fault is detected, the traction control active light will
illuminate, the Traction Control™ button will not turn the system on or
off and your vehicle should be serviced by an authorized dealer.
STEERING
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than three to five seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If excessive, check for low
power steering pump fluid level before seeking service by your dealer.
•Heavy or uneven efforts may be caused by low power steering fluid.
Check for low power steering pump fluid level before seeking service
by your dealer.
