Air Suspension (Remote Lowering Of The
Vehicle) — If Equipped
For easy entry and loading, your
vehicle can be lowered by push-
ing the key fob air suspension
lowering button two times. When
key fob lowering is requested,
the vehicle will send a series of chirps and
flashes to alert the customer that the opera-
tion has begun and will continue these alerts
until it successfully lowers. The following conditions must be met for the
vehicle to lower remotely:
• The vehicle must not already be in Entry/
Exit (Park) ride height.
• The vehicle battery must be fully charged.
• All doors must be closed.
• The key fob must be out of the vehicle.
Canceling Remote Lowering
Vehicle lowering can be cancelled at any-
time. When vehicle lowering is canceled, the
vehicle will raise up to the next defined level
and lock out the remote lowering feature until
the ignition has been cycled ON/OFF.
To cancel vehicle lowering, push the key fob
air suspension lowering button one time dur-
ing the lowering process. When vehicle low-
ering is canceled, the horn will chirp two
times and the turn signal lamps will flash four
times. Once raising is completed, the horn
will chirp one time.

AIR SUSPENSION SYSTEM
(1500 MODELS) — IF EQUIPPED
Description
The air suspension system provides full time
load leveling capability along with the benefit
of being able to adjust vehicle height by the
push of a button.Automatic height changes will occur based
on vehicle speed and the current vehicle
height. The indicator lamps and instrument
cluster messages will operate the same for
automatic changes and user requested
changes.
•
Normal Ride Height (NRH) – This is the stan-
dard position of the suspension and is
meant for normal driving.
• Off-Road 1 (OR1) (Raises the vehicle approxi-
mately 1 in (26 mm)) - This position should
be the primary position for all off-road driv-
ing 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 ve-
hicle 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 pay-
load, an instrument cluster message will be
displayed when this occurs. Refer to “In- strument Cluster Display” in “Getting To
Know Your Instrument Panel” in the Own-
er’s Manual for further information.
• Off-Road 2 (OR2) (Raises the vehicle approxi-
mately 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 instru-
ment cluster message will be displayed
when this occurs. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” in the Owner’s Manual
for further information.
• Aero Mode (Lowers the vehicle approximately
.6 in [15 mm]) – This position provides
improved aerodynamics by lowering the ve-
hicle. 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). The vehicle will return to NRH
from Aero Mode if the vehicle speed re-
mains between 30 mph (48 km/h) and
35 mph (56 km/h) for greater than 20 sec-
onds or if the vehicle speed falls below
30 mph (48 km/h).
NOTE:
Automatic Aero Mode may be disabled
through vehicle settings in the instrument
cluster when equipped with Uconnect 3.0, or
your Uconnect Radio when equipped with
Uconnect 5.0, 8.4A, or 8.4AN.
• Entry/Exit Mode (Lowers the vehicle approxi-
mately 2 in (51 mm)) - This position lowers
the vehicle for easier passenger entry and
exit as well as lowering the rear of the
vehicle for easier loading and unloading of
cargo. To enter Entry/Exit Mode, push the
“Down” button once from the NHR 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 instru-
ment cluster message will be displayed
when this occurs. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” in the Owner’s Manual
for further information.
Air Suspension Modes
The Air Suspension system has multiple
modes to protect the system in unique situa-
tions:
AERO Mode
To improve aerodynamics, the air suspension
system has a feature which will put the ve-
hicle into AERO height automatically. Refer
to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” in the Own-
er’s Manual for further information.
NOTE:
This mode is intended to be enabled with
engine running.
Tire/Jack Mode
To assist with changing a tire, the air suspen-
sion system has a feature which allows the
automatic leveling to be disabled. Refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” in the Owner’s
Manual for further information.
NOTE:
This mode is intended to be enabled with
engine running.
Transport Mode
For towing your vehicle with four wheels off
the ground, the air suspension system has a
feature which will put the vehicle into Entry/
Exit height and disable the automatic load
leveling system. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instru-
ment Panel” in the Owner’s Manual for fur-
ther information.

NOTE:
This mode is intended to be enabled with
engine running.
Wheel Alignment Mode
Before performing a wheel alignment, this
mode must be enabled. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” in the Owner’s Manual for
further information.
NOTE:
This mode is intended to be enabled with
engine running.
Protection Strategy
In order to “protect” the air suspension sys-
tem, the vehicle will disable load leveling as
required (suspension overloaded, battery
charge low, etc.). Load leveling will automati-
cally 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 fur-
ther information.AIR SUSPENSION SYSTEM (REBEL
