easier entry. When a door or the liftgate is opened, the system
memorizes and maintains that height until either all doors are closed or
the vehicle’s speed exceeds 15 mph (24 km/h). The air suspension
system will then raise the vehicle’s height to its normal position when the
ignition is turned on, all doors are closed and the transmission is shifted
from P (Park).
When the vehicle is in motion, the air suspension will adjust the vehicle
ride height to normal operating position to maximize your ride comfort.
If your vehicle is equipped with four-wheel drive and you shift into 4WD
LOW, the air suspension will not move to it’s lowest position; instead, the
ride height is raised above the normal ride height position (at speeds
below 35 mph [56 km/h]) to improve ground clearance.
If a load is added to, or removed from the vehicle, the load leveling
feature of the air suspension system will adjust the suspension to keep
the vehicle at a constant level.
When exiting the vehicle, the air suspension will automatically lower the
vehicle to its lowest height to provide easier exit. You may hear a buzz or
click from the air suspension system when the ignition is turned off. 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 shut-off switch is
located behind an access panel on
the left rear quarter trim panel, near
the liftgate. To remove the panel,
turn the control counterclockwise.
On vehicles equipped with
air suspension, turn the air
suspension and the ignition switch
off prior to jacking, hoisting or
towing your vehicle.
