OPERATION

Air Suspension Switch

The indicator lamps 1 through 5 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 position
the system is working to achieve.
When lowering, if multiple indicators are flashing, the
lowest solid indicator lamp is the position the system is
working to achieve. Pushing the height selector up once will move the
suspension one position higher from the current position,
assuming all conditions are met (i.e., ignition 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 OR2 or the highest
position allowed based on current conditions
(i.e., vehicle speed, etc.).
Pushing the height selector down once will move the
suspension one position lower from the current level,
assuming all conditions are met (i.e., ignition 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.

AIR SUSPENSION SYSTEM
(OFF-ROAD GROUP) — 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 using the toggle switch.

Rebel Air Suspension Controls

Off-Road (OR) (Raises the vehicle approximately 1 inch
[26 mm]) – This position is intended for off-roading use
only where maximum ground clearance is required. To
enter OR, push the height selector switch up once from
the NRH position while vehicle speed is below 20 mph
(32 km/h). While in OR, if the vehicle speed exceeds
25 mph (40 km/h) the vehicle height will be automati -
cally lowered to NRH. Off-Road may not be available
due to vehicle payload, an instrument cluster display
message is shown when this occurs
Úpage 98. 
Normal Ride Height (NRH) – This is the standard posi -
tion of the suspension and is meant for normal driving.
 Aero Height (Lowers the vehicle approximately
0.6 inches [15 mm]) – This position provides improved
aerodynamics by lowering the vehicle. The vehicle will
automatically enter Automatic 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 remains between 30 mph (48 km/h)
and 35 mph (56 km/h) for greater than 20 seconds or
if the vehicle speed falls below 30 mph (48 km/h).
NOTE:

 Automatic Aero mode will be disabled if a trailer is
detected to prevent shifting loads.
 Speed thresholds for raising or lowering the vehicle
only apply if Automatic Aero Mode is enabled
through vehicle settings on your Uconnect Radio.
 To enter Aero Height manually push the height
selector switch down once from NRH at any vehicle
speed. To return to NRH push the height selector
switch up once while vehicle speed is less than
56 mph (90 km/h).
 Automatic Aero Mode may be disabled through
vehicle settings on your Uconnect Radio.

138STARTING AND OPERATING
Entry/Exit Height (Lowers the vehicle approximately
3 inches [73 mm]) – This position lowers the vehicle
for easier passenger entry and exit as well as lowering
the vehicle for easier loading and unloading of cargo.
To enter Entry/Exit Mode, push the height selector
switch down twice 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 canceled. 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 Height may not be available due to vehicle payload, an
instrument cluster display message is shown when this
occurs
Úpage 98.
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
Úpage 191.
Default Ride Height:
 Select Aero Height or Normal Ride Height as the default
for all vehicle speeds and operation. This is the
selected height that the suspension will level for speed
changes (e.g. raising from Entry/Exit Height at speed,
lowering from Off-Road Height at speed, etc.).
 Default ride height can be changed by manually
adjusting the Air Suspension switch to Normal Ride
Height or Aero Ride Height and staying in the selected
height for 2.5 seconds. It will be stored as the default
ride height and the height will be maintained until a
new default ride height is selected.
NOTE:If equipped with a touchscreen radio, all enabling/
disabling of air suspension features must be done through
the radio
Úpage 191.
AIR SUSPENSION MODES
The air suspension system has multiple modes to protect
the system in unique situations:
Automatic Aero Mode
To improve aerodynamics, the air suspension system has
a feature which will put the vehicle into Aero height
automatically at higher speeds

STARTING AND OPERATING151
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster displays
“ACC/FCW Unavailable Service Required” or “Cruise/FCW
Unavailable Service Required”, there may be an internal
system fault or a temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable under
normal conditions, ACC will be temporarily unavailable.
If this occurs, try activating ACC again later, following an
ignition cycle. If the problem persists, see an authorized
dealer.
Precautions While Driving With ACC
NOTE:
Aftermarket add-ons such as snowplows, lift kits, and
brush/grille bars can hinder module performance.
Ensure the radar/camera has no obstructions in the
field of view.
 Height modifications can limit module performance
and functionality.
 Do not put stickers or easy passes over the camera/
radar field of view.
 Any modifications to the vehicle that may obstruct the
field of view of the radar/camera are not recom -
mended.
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or
unexpectedly. The driver needs to stay alert and may need
to intervene. The following are examples of these types of
situations:
TOWING A TRAILER
ACC while towing a trailer is recommended only with an
Integrated Trailer Brake Controller. Aftermarket trailer
brake controllers will not activate the trailer brakes when
ACC is braking.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may not be sufficient distance
to the vehicle ahead. The offset vehicle may move in and
out of the line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.

Offset Driving Condition Example

TURNS AND BENDS
When driving on a curve with ACC engaged, the system
may increase or decrease the vehicle speed for stability,
with no vehicle ahead detected. Once the vehicle is out of
the curve, the system will resume your original set speed.
This is a part of normal ACC system functionality.
NOTE:On tight turns ACC performance may be limited.
USING ACC ON HILLS
ACC performance may be limited when driving on hills.
ACC may not detect a vehicle in your lane depending on
the speed, vehicle load, traffic conditions, and the
steepness of the hill.

STARTING AND OPERATING173
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR
Úpage 172.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or
temporary) loaded in or on the trailer in its “loaded and
ready for operation” condition.
The recommended way to measure GTW is to put your fully
loaded trailer on a vehicle scale. The entire weight of the
trailer must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your vehicle and
trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR
Úpage 172.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball by
the trailer. You must consider this as part of the load on
your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that can be
installed between the hitch receiver and the trailer tongue
that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
The electronic TSC (If equipped) recognizes a swaying
trailer and automatically applies individual wheel brakes
and/or reduces engine power to attempt to eliminate the
trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some
other connecting point of the vehicle. These kinds of
hitches are commonly used to tow small and medium
sized trailers.
WARNING!
If the gross trailer weight is 5,000 lb (2,267 kg) or
more, it is recommended to use a weight-distributing
hitch to ensure stable handling of your vehicle. If you
use a standard weight-carrying hitch, you could lose
control of your vehicle and cause a collision.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose control
of the vehicle and have a collision.

STARTING AND OPERATING175
RECOMMENDED DISTRIBUTION HITCH
ADJUSTMENT
Towing With Air Suspension — If Equipped

1. Verify that the vehicle is at the 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. Enable tire jack mode through the instrument cluster or touchscreen radio settings. Tire jack mode will be
canceled and the procedure must be restarted if the
vehicle is driven at speeds above 5 mph (8 km/h).
4. Measure the height from the top of the front wheel opening on the fender to ground; this is height H1.

Measuring Height (H)

5. Attach the trailer to the vehicle without the weight-distributing bars connected.
6. Measure the height from the top of the front wheel opening on the fender to the ground; this is height H2.
7. Install and adjust the tension in the weight-distributing bars per the manufacturer’s
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]). 8. Use the instrument cluster or touchscreen radio
settings and switch off tire jack mode. Make sure the
truck returns to normal ride height. Perform a visual
inspection of the trailer and weight-distributing hitch
to confirm the manufacturer’s recommendations
have been met.
9. The truck can now be driven.
NOTE:For all towing conditions, we recommend towing with
Tow/Haul mode engaged.
