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 height selector
switch up 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.
330 STARTING AND OPERATING

Protection Strategy
In order to “protect” the air suspension system, the vehicle
will disable load leveling as required (suspension over-
loaded, battery charge low, etc.). Load leveling will auto-
matically resume as soon as system operation requirements
are met. See your authorized dealer if system does not
resume.
NOTE:If towing with air suspension refer to “Trailer
Towing” in “Starting And Operating” for further informa-
tion.
Instrument Cluster Display Messages
When the appropriate conditions exist, a message will
appear in the instrument cluster display. Refer to “Instru-
ment Cluster Display” in “Getting To Know Your Instru-
ment Panel” for further information.
An audible chime will be heard whenever a system error
has been detected.
See your authorized dealer for system service if normal
operation does not resume.

332 STARTING AND OPERATING

The indicator lamps 1 through 4 will illuminate to show the
current position of the vehicle. Flashing indicator lamps
will show a position which the system is working to
achieve. When raising or lowering, the flashing indicator
lamp is the position the system is working to achieve.
Pushing the height selector switch up once will move the
suspension one position higher from the current position,
assuming all conditions are met (i.e. key in ON/RUN
position, engine running, speed below threshold, etc). The
height selector switch can be pushed up multiple times,
each push will raise the requested level by one position up
to a maximum position of OR or the highest position
allowed based on current conditions (i.e. vehicle speed,
etc).
Pushing the height selector switch down once will move
the suspension one position lower from the current level,
assuming all conditions are met (i.e. key in ON/RUN
position, engine running, doors closed, speed below
threshold, etc). The height selector switch can be pushed
down multiple times, each push will lower the requested
level by one position down to a minimum of Entry/Exit
Mode or the lowest position allowed based on current
conditions (i.e. vehicle speed, etc.)Automatic height changes will occur based on vehicle
speed and the current vehicle height. The indicator lamps
and instrument cluster display messages will operate the
same for automatic changes and user requested changes.
•
Off-Road 1 (OR1) – Indicator lamps 4, 3, 2, and 1 will be
illuminated when the vehicle is in OR1.
• Normal Ride Height (NRH) – Indicator lamps 4, 3, and

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.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires must
be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
406 STARTING AND OPERATING

Recommended Distribution Hitch Adjustment
Towing With 1500 Air Suspension
1. Set air suspension to normal ride height. No action isrequired if already in normal ride height.
NOTE: The vehicle must remain in the engine run position
with all doors closed while attaching a trailer for proper
leveling of the air suspension system.
2. Position the truck to be ready to connect to the trailer (do not connect the trailer).
3. Under the instrument cluster or touch screen radio settings, enable tire jack mode. Tire jack mode will be
canceled and procedure must be restarted if the vehicle
is driven at speeds above 5mph (8 kmh).
4. Measure the height of the top of the front wheel opening on the fender to ground, this is height H1. 5. Attach the trailer to the vehicle without the weight
distribution bars connected.
6. Measure the height of the top of the front wheel opening on the fender to ground, this is height H2.
7. Install and adjust the tension in the weight distributing bars per the manufacturers’ recommendations so that
the height of the front fender is approximately (H2-H1)/
3+H1 (about 1/3 the difference between H2 and H1
above normal ride height [H1]).
