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 FCA 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 FCA recommendations have been
met. 9. The truck can now be driven.

TOWING TIPS
Before towing, practice turning, stopping, and
backing up the trailer in an area located away
from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include a drive
strategy to avoid frequent shifting when towing.
However, if frequent shifting does occur while in
DRIVE, select TOW/HAUL mode or select a lower
gear range (using the Electronic Range Select
(ERS) shift control).
NOTE:
Using TOW/HAUL mode or selecting a lower
gear range (using the ERS shift control) while
operating the vehicle under heavy loading
conditions will improve performance and extend transmission life by reducing excessive
shifting and heat build up. This action will also
provide better engine braking.
Tow/Haul Mode
To reduce potential for automatic transmission
overheating, activate TOW/HAUL mode when
driving in hilly areas, or select a lower gear
range (using the (ERS) shift control) on more
severe grades.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Cruise Control, if you experi
-
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Cruise Control in flat terrain and with
light loads to maximize fuel efficiency.
Air Suspension System
To aid in attaching/detaching the trailer from
the vehicle, the air suspension system can be
used Ú page 165. NOTE:
The vehicle must remain in the engine running
position while attaching a trailer for proper
leveling of the air suspension system.
SNOWPLOW
Snowplow Prep Packages are available as a
factory installed option. These packages
include components necessary to equip your
vehicle with a snowplow.
NOTE:
Before installation of a snowplow it is highly
recommended that the owner/installer obtain
and follow the recommendations contained
within the current Body Builders Guide. See an
authorized dealer, installer or snowplow manu
-
facturer for this information. There are unique
electrical systems that must be connected to
properly ensure operator safety and prevent
overloading vehicle systems.

228STARTING AND OPERATING
BEFORE PLOWING
Check the hydraulic system for leaks and
proper fluid level.
Check the mounting bolts and nuts for proper
tightness.
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 Builders Guide.

1. The maximum number of occupants in the
truck should not exceed two.

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.
WARNING!
Attaching a snowplow to this vehicle could
adversely affect performance of the airbag
system in a collision. Do not expect that the
airbag will perform as described earlier in this
manual.
CAUTION!
The “Lamp Out” indicator could illuminate if
exterior lamps are not properly installed.

ensure the vehicle is set to Normal Ride Height.
4. Using a ballpoint pen or similar object, push and hold the recessed transfer case N
(Neutral) button (at the center of the
transfer case switches). The N (Neutral)
indicator light will illuminate, and remain lit,
when the shift to N (Neutral) is complete.
After the shift is completed and the N
(Neutral) light stays on, release the N
(Neutral) button.
5. Release the parking brake. 6. Shift the transmission into REVERSE.
7. Release the brake pedal for five seconds
and ensure that there is no vehicle
movement.
8. Repeat steps 6 and 7 with the transmission in DRIVE.
9. Shift the transmission to NEUTRAL. Apply the parking brake. Turn off the engine. For
vehicles with Keyless Enter-N-Go, push and
hold the ENGINE START/STOP button until
the engine shuts off. The transmission will
automatically select PARK when the engine

13. Release the parking brake.
14. Turn the ignition OFF.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (Neutral) position without first
fully engaging the parking brake. The transfer
case N (Neutral) position disengages both the
front and rear driveshafts from the power -
train and will allow the vehicle to roll, even if
the transmission is in PARK. The parking
brake should always be applied when the
driver is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be cer -
tain that the transfer case is fully in N (Neu -
tral) before recreational towing to prevent
damage to internal parts.
