Overload and Overheat Protection
Overload protection is designed to protect the air
suspension system and is an indication to the driver
that the vehicle is overloaded.
If the rear suspension remains at a low height, the rear
axle load has exceeded GAWR (Gross Axle Weight
Rating). When the overload protection mode is
activated, the compressor operates for about 30 seconds
to one minute without raising the vehicle depending on
the amount of overload. This will continue each time the
ignition is turned on until the rear axle load is reduced
below GAWR. See “GAWR” in the Index.
If the system overheats, it will shut down and stop all
leveling functions until the system cools down. During
this time the SERVICE AIR SUSPENSION message
will appear in the DIC. See “Driver Information Center”
in the Index for more information.
Selectable Extended Rear Ride
Height (If Equipped)
This feature comes as part of the electronically
controlled air suspension system.
The selectable rear ride height allows you to raise the
rear of the vehicle approximately 2 inches (5 cm) over
the normal ride height. This can be helpful when driving
off
-road where you may need more ground clearance to
clear an obstacle.
The button that controls this
feature is located on the
instrument panel to the right
of the steering wheel.
