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.

178STARTING AND OPERATING
Using TRSC

Trailer Reverse Steering Control Knob

To use the system, place the gear selector in PARK and put
your foot on the brake. Push the activation button located
above the TRSC knob in the center stack. The LED on the
button will glow solid and the instrument cluster display
will direct you to shift to REVERSE. Once in REVERSE the
system is active. Remove hands from the steering wheel
and slowly back up while turning the TRSC knob in the
direction you want the trailer to go. Turning the knob
clockwise will cause the trailer to turn right. Turning the
knob counterclockwise will cause the trailer to turn left.
If you release the knob, it will return to its center position,
and the trailer will back up in a straight line. Continue to control the accelerator and brake while
backing the trailer up.
NOTE:While active, TRSC will automatically disable the Rear Park
Assist system if it was previously enabled.
The system will limit the top speed your vehicle can travel
in REVERSE while using the feature. If needed, you can
shift to DRIVE or NEUTRAL to pull forward to get more
room or straighten out the trailer, and shift back to
REVERSE without the need to reactivate the feature.
The feature will cancel after 30 seconds in DRIVE or when
the vehicle speed reaches 8 mph (12 km/h).
To cancel out of the feature, come to a stop and shift to
PARK, or push the TRSC activation button.
Instrument Cluster Messages:

“Calibrate Trailer ” will display when a trailer is not
calibrated and the vehicle is at a standstill while the
button is pushed.
 “Calibrating Trailer” will display when the trailer is not
calibrated and the vehicle is moving while the button is
pushed.
 “To Activate Trailer Steering Shift To P” will display
when the trailer is calibrated successfully, the TRSC
activation button is pushed and the vehicle is not in
PARK.
 “Trailer Steering Ready, Shift To Reverse” will display
when the button is pushed, trailer is calibrated and the
vehicle is in PARK. 
“Trailer Steering Active” will display after the driver
shifts to REVERSE and indicates the feature is active.
 “Trailer Steering Unavailable” will display if there is a
fault in the system preventing activation, the driver’s
door is open, the driver’s seat belt is unbuckled, or the
tailgate is open.
Other reasons the feature may cancel:
 The driver overrides steering by placing hands on the
steering wheel.
 Trailer tracking is lost.
 If the trailer angle becomes excessive, the brakes apply
bringing the vehicle to a stop and then applying the
parking brake.
 Trailer steering button is pushed while active.
 Vehicle speed goes over 8 mph (12 km/h).
 Driver door is open and seat belt is unbuckled.
 Transmission shifted to PARK.
Trailer Memory
The trailer steering system will automatically retain the
calibration of the previous five trailers connected, so
recalibration will not be necessary when hooking up.
The next time the vehicle is started, place the vehicle in
DRIVE and drive a short distance. The TRSC system can
then be activated.
NOTE:Trailers may look different during day and night condi -
tions. In such cases, the trailer may need to recalibrate.
CAUTION!
Always observe the position of the trailer and
surroundings using the camera and mirrors to avoid
damage to the truck or trailer.

23_DT_OM_EN_USC_t.book Page 178

STARTING AND OPERATING179
(Continued)
Some trailers (such as boat trailers) will need to
recalibrate while loaded and unloaded.
NOTE:

The system may not detect a trailer in low light condi -
tions. In sunny conditions, the performance may be
degraded as shadows pass over the trailer.
 The driver is always responsible for safe operation of
truck and trailer.
 The driver is always in control of the truck as well as the
trailer and is responsible for controlling the throttle and
brakes.
 The system may not function when the camera lens is
blocked, blurred (covered with water, snow, ice, dirt,
etc) and will not work unless the tailgate is upright and
fully latched.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended. Perform the maintenance listed in the Scheduled
Servicing section for the proper maintenance intervals
Úpage 333. When towing a trailer, never exceed the
GAWR or GCWR ratings.
Towing Requirements — Tires
 Do not attempt to tow a trailer while using a compact
spare tire.
 Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
 Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle.
 Check the trailer tires for proper tire inflation pressures
before trailer usage.
 Check for signs of tire wear or visible tire damage
before towing a trailer.
 Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
 For further information
Úpage 370.
CAUTION!
Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
 Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps the
engine and other parts of the vehicle wear in at the
heavier loads.
WARNING!
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering cargo
that is not fully secured, dynamic load shifts can
occur that may be difficult for the driver to control.
You could lose control of your vehicle and have a
collision.
 When hauling cargo or towing a trailer, do not over -
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to
brakes, axle, engine, transmission, steering, suspen -
sion, chassis structure or tires.
 Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
 Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always, block or
"chock" the trailer wheels.
 GCWR must not be exceeded.
Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded :
 GVWR
 GTW
 GAWR
 Tongue weight rating for the trailer hitch utilized

Adjusting GAIN
NOTE:This should only be performed in a traffic free environment
at speeds of approximately 20–25 mph (30–40 km/h).
1. Make sure the trailer brakes are in good working
condition, functioning normally and properly
adjusted. See your trailer dealer if necessary.

2. Hook up the trailer and make the electrical connections according to the trailer manufacturer's
instructions.
3. When a trailer is plugged in with electric or EOH brakes, the trailer connected message should appear
in the instrument cluster display (if the connection is
not recognized by the ITBM, braking functions will not
be available), the GAIN setting will illuminate and the
correct type of trailer must be selected from the
instrument cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” appears on the screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”. 6. Push the UP or DOWN buttons until the Trailer Brake

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.

RECREATIONAL TOWING —
F
OUR-WHEEL DRIVE MODELS
NOTE:The transfer case must be shifted into N (Neutral) for
recreational towing. The transmission must be shifted into
PARK for recreational towing. Refer to the following for the
proper transfer case N (Neutral) shifting procedure for
your vehicle.
Shifting Into N (Neutral)
Use the following procedure to prepare your vehicle for
recreational towing.
1. Bring the vehicle to a complete stop on level ground,
with the engine running. Apply the parking brake.

2. Press and hold the brake pedal.
3. Shift the transmission to NEUTRAL. The driver's door must be closed (or the driver's seat belt buckled) so
that the transmission will remain in NEUTRAL when
the brake pedal is released.
NOTE:If vehicle is equipped with air suspension, 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.
CAUTION!
DO NOT dolly tow any 4WD vehicle. Towing with only
one set of wheels on the ground (front or rear) will
cause severe transmission and/or transfer case
damage. Tow with all four wheels either ON the
ground, or OFF the ground (using a vehicle trailer).
 Tow only in the forward direction. Towing this vehicle
backwards can cause severe damage to the transfer
case.
 Before recreational towing, the transfer case must
be in N (Neutral). To be certain the transfer case is
fully in N (Neutral), perform the procedure outlined
under “Shifting Into N (Neutral)”. Internal transmis -
sion damage will result, if the transfer case is not in
N (Neutral) during towing.
 The transmission must be in PARK for recreational
towing.
 Ensure that the Electric Park Brake is released, and
remains released, while being towed.
Towing this vehicle in violation of the above require -
ments can cause severe transmission and/or
transfer case damage. Damage from improper
towing is not covered under the New Vehicle Limited
Warranty.
 Do not disconnect the rear driveshaft because fluid
will leak from the transfer case, causing damage to
internal parts.
 Do not use a fascia/bumper-mounted clamp-on tow
bar on your vehicle. The fascia/bumper face bar will
be damaged.
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
powertrain 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!CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in N (Neutral) before
recreational towing to prevent damage to internal parts.

NOTE:
Steps 3 and 4 are requirements that must be met
before pushing the button to shift out of N (Neutral),
and must continue to be met until the shift has been
completed. If any of these requirements are not met
before pushing the button or are no longer met during
the shift, the N (Neutral) indicator light will flash contin -
uously until all requirements are met or until the button
is released.
 The ignition must be in the ON/RUN mode for a shift to
take place and for the position indicator lights to be
operable. If the ignition is not in the ON/RUN mode, the
shift will not take place and no position indicator lights
will be on or flashing.
 A flashing N (Neutral) position indicator light indicates
that shift requirements have not been met.
DRIVING TIPS
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the rear (driving)
wheels.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
Flowing/Rising Water
Shallow Standing Water
Although your vehicle is capable of driving through shallow
standing water, consider the following Cautions and
Warnings before doing so.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).
WARNING!
Do not drive on or across a road or path where water is
flowing and/or rising (as in storm run-off). Flowing water
can wear away the road or path's surface and cause
your vehicle to sink into deeper water. Furthermore,
flowing and/or rising water can carry your vehicle away
swiftly. Failure to follow this warning may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
WARNING!
Driving through standing water limits your vehicle’s
traction capabilities. Do not exceed 5 mph (8 km/h)
when driving through standing water.
 Driving through standing water limits your vehicle’s
braking capabilities, which increases stopping
distances. Therefore, after driving through standing
water, drive slowly and lightly press on the brake
pedal several times to dry the brakes.
 Failure to follow these warnings may result in injuries
that are serious or fatal to you, your passengers, and
others around you.
