If the power steering system breaks down (or if the engine is turned

off), you can steer the vehicle manually, but it takes more effort.

If the steering wanders or pulls, check for:

• Underinflated tire(s) on any wheel(s)

• Uneven vehicle loading

• High crown in center of road

• High crosswinds

• Wheels out of alignment

• Loose or worn suspension components

Variable assist steering

Your vehicle is equipped with variable assist power steering. At low

engine RPM, steering assist will adjust to reduce efforts and improve low

speed maneuverability. At high engine RPM, the assist will adjust to

improve steering feel at high speeds.

If the amount of effort required to steer your vehicle changes while

driving at a constant engine RPM, have the power steering system

checked by your authorized dealer.

AIR SUSPENSION SYSTEM (IF EQUIPPED)

The air suspension system is designed to improve ride, handling and

general vehicle performance during:

• Certain road conditions

• Steering maneuvers

• Acceleration

This system keeps the rear of your vehicle at a constant level by

automatically adding air or releasing air from the springs. If you exceed

the load limit, the rear air suspension may not operate. The air

suspension system will stay active for 40 minutes after the ignition is

turned off to accommodate any load changes. (The air compressor may

run when the vehicle is off; this is normal.)

The air suspension system can be enabled or disabled through the

message center. Refer to Message center in the Instrument cluster
