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).

AXLE LOCK SYSTEM — IF EQUIPPED
This vehicle is equipped with an electronically locking rear
differential. When engaged, this differential locks the axle
shafts forcing the wheels to spin at an equal rate. The
locking of the rear differential should only be engaged
during low-speed, extreme off-road situations 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.
AXLE LOCK Button
The locking rear axle is controlled by the AXLE LOCK
button.
Under normal driving conditions, the rear axle should be
unlocked.
During the command to lock the rear axle, the indicator
light will flash until the axle is locked. After the lock
command has been successfully executed, the light will
remain on solid.
Operating in 4WD LOW the locker can be engaged up to
40 mph (64 km/h) and will remain engaged throughout
the 4WD LOW speed range.
Operating the locker in 2WD, 4WD AUTO, and 4WD
LOCK/HIGH, the locker can be engaged up to 20 mph
(32 km/h). While driving with the locker engaged, if speed
exceeds 25 mph (40 km/h), the locker will automatically disengage, but will automatically re-engage at 20 mph
(32 km/h).
NOTE:Left to right wheel speed difference may be necessary to
allow the rear axle to fully lock. If the indicator light is
flashing after selecting the rear axle lock mode, drive the
vehicle in a turn or on loose gravel to expedite the locking
action.
The axle locker could become torque locked due to side to
side loads on the rear axle. Driving slowly while turning the
steering wheel from a left hand turn to a right hand turn or
driving in REVERSE for a short distance may be required to
release the torque lock and unlock the axles.
To unlock the rear axle, push the AXLE LOCK button.
The AXLE LOCK indicator light will go out when the rear
axle is unlocked.
LIMITED-SLIP DIFFERENTIAL —
IF EQUIPPED
The limited-slip differential provides additional traction on
snow, ice, mud, sand and gravel, particularly when there is
a difference between the traction characteristics of the
surface under the right and left rear wheels. During
normal driving and cornering, the limited-slip unit
performs similarly to a conventional differential. On
slippery surfaces, however, the differential delivers more
of the driving effort to the rear wheel having the better
traction.
CAUTION!
Do not lock the rear axle on hard surfaced roads. The
ability to steer the vehicle is reduced and damage to
the drivetrain may occur when the axle is 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.

STARTING AND OPERATING185
BEFORE PLOWING
Check the hydraulic system for leaks and proper fluid
level.
Check the mounting bolts and nuts for proper tight -
ness.
Check the runners and cutting edge for excessive wear.
The cutting edge should be ¼ to ½ inches
(6 cm to 1.2 cm) above ground in snow plowing
position.
Check that snowplow lighting is connected and
functioning properly.
SNOWPLOW PREP PACKAGE MODEL
A
VAILABILITY
For Information about snowplow applications visit
www.ramtrucks.com or refer to the current Body Builder’s
Guide.
1. The maximum number of occupants in the truck
should not exceed one.
2. The total GVWR, Front GAWR or the Rear GAWR should never be exceeded.
3. Cargo capacity will be reduced by the addition of options or passengers, etc.
The loaded vehicle weight, including the snowplow
system, all aftermarket accessories, driver, passengers,
options, and cargo, must not exceed either the Gross
Vehicle Weight (GVWR) or Gross Axle Weight (GAWR)
ratings. These weights are specified on the Safety Compliance Certification Label on the driver's side door
opening.
NOTE:Detach the snowplow when transporting passengers.
Vehicle front end wheel alignment was set to
specifications at the factory without consideration for the
weight of the plow. Front end toe-in should be checked
and reset if necessary at the beginning and end of the
snowplow season. This will help prevent uneven tire wear.
The blade should be lowered whenever the vehicle is
parked.
Maintain and operate your vehicle and snowplow
equipment following the recommendations provided by
the specific snowplow manufacturer.
OVER THE ROAD OPERATION WITH
S
NOWPLOW ATTACHED
The blade restricts air flow to the radiator and causes the
engine to operate at higher than normal temperatures.
Therefore, when transporting the plow, angle the blade
completely and position it as low as road or surface
conditions permit. Do not exceed 40 mph (64 km/h). The
operator should always maintain a safe stopping distance
and allow adequate passing clearance.
NOTE:Lane Departure Warning / Lane Keep Assist is not
available when a snow plow is attached.
OPERATING TIPS
Under ideal snow plowing conditions, 20 mph (32 km/h)
should be maximum operating speed. The operator should
be familiar with the area and surface to be cleaned.
Reduce speed and use extreme caution when plowing
unfamiliar areas or under poor visibility.
GENERAL MAINTENANCE
Snowplows should be maintained in accordance with the
plow manufacturer's instructions.
Keep all snowplow electrical connections and battery
terminals clean and free of corrosion.
When plowing snow, to avoid transmission and drivetrain
damage, the following precautions should be observed:
Operate with transfer case in 4WD LOW when plowing
small or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4WD HIGH.
Vehicles with automatic transmissions should use
4WD LOW when plowing deep or heavy snow for
extended periods of time to avoid transmission over -
heating.
Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal while shifting
the transmission.
