STARTING AND OPERATING 321
33 mph (53 km/h). Once the vehicle speed goes below15 mph (24 km/h) the vehicle height will begin to lower. If
the vehicle speed remains between 15 mph (24 km/h) and
25 mph (40 km/h) for greater than 60 seconds, or the
vehicle speed exceeds 25 mph (40 km/h) the Entry/Exitchange will be cancelled. To return to Normal Height
Mode, push the height selector switch up once while in
Entry/Exit or drive the vehicle over 15 mph (24 km/h).
Entry/Exit mode may not be available due to vehicle
payload, an instrument cluster message will be displayed
when this occurs. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further
information.
NOTE:
Entry/Exit mode may be achieved using your key fob for
easier entry/loading. Refer to “Keys” in “Getting To Know
Your Vehicle” for further information. The system requires that the ignition be in the ON/RUN
position or the engine running for all user requested
changes. When lowering the vehicle all of the doors, must be
closed. If a door is opened at any time while the vehicle is
lowering the change will not be completed until the open
door(s) is closed.
This system uses a lifting and lowering pattern which keeps
the headlights from incorrectly shining into oncoming
traffic. When raising the vehicle, the rear of the vehicle will
move up first and then the front. When lowering the vehicle,
the front will move down first and then the rear.
After the engine is turned off, it may be noticed that the air
suspension system operates briefly, this is normal. The
system is correcting the position of the vehicle to ensure a
proper appearance.
To assist with changing a spare tire, the air suspension
system has a feature which allows the automatic leveling to
be disabled. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further infor
-
mation.
CAUTION!
When in ENTRY/EXIT setting, be aware of your
surroundings, you may not have the clearance required
for certain areas and vehicle damage may occur.
