for you to steer. This occurs to prevent internal overheating and
permanent damage to your steering system. If this should occur, you will
neither lose the ability to steer the vehicle manually nor will it cause
permanent damage. Typical steering and driving maneuvers will allow the
system to cool and steering assist will return to normal.
When a steering system error is detected, steering messages may appear
in the information display.
Steering Tips
If the steering wanders or pulls, check for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper vehicle alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
AUTO LEVELING SUSPENSION SYSTEM (if equipped)
The automatic leveling suspension system is designed to improve ride,
handling and general vehicle performance during:
• Certain road conditions
• Steering maneuvers
• Braking
• Acceleration
• Towing
This system keeps the rear of your vehicle at a constant level through a
hydraulic pump inside each rear shock. Depending on the payload or
road surface conditions it will take approximately 2 miles (3.2 km) for
the leveling to complete.
If the loaded vehicle is not moved for approximately 12 hours, the
leveling system may bleed down to a lower height. This can be especially
apparent if a trailer is left attached to the parked vehicle for long periods
of time. You must drive your vehicle in order to re-level the suspension.
If a self-equalizing hitch is being used, your vehicle should be drive
approximately 2 miles (3.2 km) with the trailer prior to adjusting
(leveling) the hitch.
