Speed Sensitive Power Steering
The steering system in your vehicle is speed
sensitive. This means that the steering effort is
light for parking and heavier for highway
driving. However, if you have to swerve around
an object or another vehicle, your steering will
have full power assist.
Rear Air Suspension System
(If equipped)
If your vehicle is equipped with an automatic
load leveling rear air suspension system, it will
maintain the rear vehicle height at a constant
level by automatically adding air or releasing air
from the rear air springs to offset changes in
vehicle loads.
A shutoff switch is located in the trunk on the
right hand vertical trim panel. If this switch is in
the OFF position, the automatic leveling system
will not operate. The switch should be OFF
whenever jacking up or towing the vehicle. If
you have the mechanical cluster, "AIR SUSP"
will appear in the cluster, if you have an
electronic cluster, "CHECK AIR SUSPENSION"
will appear in the message center when the
ignition switch is in the ON position, and either
the shutoff switch is in the OFF position, or a
system fault has been detected.
Normal vehicle operation does not require any
action by the driver.
On vehicles equipped with Air
Suspension, turn OFF the Air Suspension
switch prior to jacking, hoisting or towing
your vehicle.
