NOTE:The vehicle will automatically enter Aero Mode
when the vehicle speed remains between 62 mph
(100 km/h) and 66 mph (106 km/h) for greater than 20
seconds or if the vehicle speed exceeds 66 mph
(106 km/h).
• Normal Ride Height (NRH) – This is the standard
position of the suspension and is meant for normal
driving.
• Off-Road 1 (OR1) (Raises the vehicle approximately
1 in [26 mm]) – This position should be the primary
position for all off-road driving until Off Road 2 (OR2)
is needed. A smoother and more comfortable ride will
result. To enter OR1, push the “Up” button once from
the NRH position while the vehicle speed is below
35 mph (56 km/h). When in the OR1 position, if the
vehicle speed remains between 40 mph (64 km/h) and
50 mph (80 km/h) for greater than 20 seconds or if the
vehicle speed exceeds 50 mph (80 km/h), the vehicle will be automatically lowered to NRH. Off-Road 1
may not be available due to vehicle payload, an
EVIC/DID message will be displayed when this oc-
curs. Refer to “Electronic Vehicle Information Center
(EVIC) or Driver Information Display (DID)” in “Un-
derstanding Your Instrument Panel” for further infor-
mation.
• Off-Road 2 (OR2) (Raises the vehicle approximately
2 in [51 mm]) – This position is intended for off-
roading use only where maximum ground clearance is
required. To enter OR2, push the “Up” button twice
from the NRH position or once from the OR1 position
while vehicle speed is below 20 mph (32 km/h). While
in OR2, if the vehicle speed exceeds 25 mph (40 km/h)
the vehicle height will be automatically lowered to
OR1. Off-Road 2 may not be available due to vehicle
payload, an EVIC/DID message will be displayed

button once from the NRH while the vehicle speed is
below 33 mph (53 km/h). Once the vehicle speed goes
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
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 EVIC/DID mes-
sage will be displayed when this occurs. Refer to
“Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID)” in “Understanding
Your Instrument Panel” for further information.
NOTE: Entry/Exit mode may be achieved using your
key fob for easier entry/loading. Refer to “A Word About
Your Keys” in “Things To Know Before Starting Your
Vehicle” for further information. •
When in ENTRY/EXIT setting, be aware of your
surroundings, you may not have the clearance re-
quired 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 on-
coming 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.

516 STARTING AND OPERATING

The indicator lamps 3 through 6 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, if multiple indicator lamps are
flashing, the highest flashing indicator lamp is the posi-
tion the system is working to achieve. When lowering, if
multiple indicators are flashing, the lowest solid indica-
tor lamp is the position the system is working to achieve.
Pushing the “UP” button 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 “UP”
button can be pushed multiple times, each push will raise
the requested level by one position up to a maximum
position of OR2 or the highest position allowed based on
current conditions (i.e. vehicle speed, etc).
Pushing the “DOWN” button once will move the suspen-
sion 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 “DOWN” button can be pushed 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 EVIC/DID messages will operate the same for
automatic changes and user requested changes.

— IF EQUIPPED
Description
The air suspension system is a rear leveling ride height
system. The main purpose of this system is to maintain
the truck’s rear ride height level.
Rear Leveling Ride Height Switch
518 STARTING AND OPERATING

Normal Ride Height (NRH)– This is the standard
position of the suspension and is meant for normal
driving.
Trailer Mode (Lowers the vehicle approximately 1 in (25
mm) – This position will lower the rear suspension and
provide load leveling for all loading conditions including
towing a trailer. After the “ALT TRAILER HEIGHT”
button has been pushed, it will blink continuously until
the trailer height has been achieved.
The system requires that the ignition be in ON/RUN
position or the engine running with zero vehicle speed
for all user requested changes.
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. 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
“Understanding Your Instrument Panel” for further in-
formation.
WARNING!
The air suspension system uses a high pressure
volume of air to operate the system. To avoid per-
sonal injury or damage to the system, see your
authorized dealer for service.
Air Suspension Modes
The Air Suspension system has multiple modes to protect
the system in unique situations:
Tire/Jack Mode
To assist with changing a spare tire, the air suspension
system has a feature which allows the automatic leveling

AXLE LOCKER SYSTEM — POWER WAGON
MODELS ONLY (IF EQUIPPED)
This vehicle is equipped with electronically locking front
and rear differentials. These differentials, when engaged,
mechanically lock together the axle shafts forcing the
wheels to spin at an equal rate. This allows the vehicle to maintain its momentum and prevents it from becoming
stuck. The locking front and rear differentials should only
be engaged during low-speed, extreme off-road situa-
tions where one wheel is likely to not be in contact with
the ground. It is not recommended to drive the vehicle
with the differentials locked on pavement due to the
reduced ability to turn and speed limitations.
CAUTION!
•
Do not lock the front or rear axle on hard surfaced
roads. The ability to steer the vehicle is reduced
and damage to the drivetrain may occur when the
axles are locked on hard surfaced roads.
• Do not try to lock the rear axle if the vehicle is
stuck and the tires are spinning. You can damage
drivetrain components. Lock the rear axle before
attempting situations or navigating terrain, which
could possibly cause the vehicle to become stuck.
