below 15 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/Exit change will be cancelled. To return to
Normal Height Mode, push the “Up” button twice 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 display message
will be shown when this occurs. Refer to “Instrument
Cluster Display” in “Getting To Know Your Instrument
Panel” for further information.
CAUTION!
When in ENTRY/EXIT setting, be aware of your sur-
roundings, you may not have the clearance required for
certain areas and vehicle damage may occur.
The system requires that the ignition be in 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 oncom-
ing 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
information.
NOTE:
If equipped with a touch screen radio all enabling/
disabling of air suspension features must be done through
the radio. Refer to “Uconnect Settings” in “Multimedia” for
further information.
WARNING!
The air suspension system uses a high pressure vol-
ume of air to operate the system. To avoid personal

NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turn on
if the gas cap is not secured properly. Make sure that the
gas cap is tightened each time the vehicle is refueled.
WARNING!
Static electricity can cause an ignition of flammable
liquid, vapor or gas in any vehicle or trailer. To reduce
risk of serious injury or death when filling containers:
•Always place container on the ground before filling.
• Keep the pump nozzle in contact with the container
when you are filling it.
• Use only approved containers for flammable liquid.
• Do not leave container unattended while filling.
• A static electric charge could cause a spark and fire
hazard.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed,
or damaged, a loose gascap indicator will dis-
play in the instrument cluster telltale display
area. Refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
Tighten the fuel filler cap properly and push the RIGHT
button to turn off the message. If the problem continues,
the message will appear the next time the vehicle is started.
VEHICLE LOADING
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.
