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 
conditions. In such cases, the trailer may need to 
recalibrate. 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 
conditions. In sunny conditions, the perfor
-
mance may be degraded as shadows pass over 
the trailer.
The driver is always responsible for safe opera -
tion 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.
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.

220STARTING AND OPERATING  
(Continued)
Perform the maintenance listed in the Scheduled 
Servicing section for the proper maintenance 
intervals  
Úpage 393. 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  Ú page 444.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system 
or vacuum system of your vehicle with that of 
the trailer.
An electronically actuated trailer brake 
controller is required when towing a trailer with 
electronically actuated brakes. When towing a 
trailer equipped with a hydraulic surge actuated 
brake system, an electronic brake controller is 
not required.
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 
overload your vehicle or trailer. Overloading 
can cause a loss of control, poor performance 
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure 
or tires.
CAUTION!
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.
WARNING!

STARTING AND OPERATING221
Trailer brakes are recommended for trailers 
over 1,000 lb (453 kg) and required for trailers 
in excess of 2,000 lb (907 kg).Integrated Trailer Brake Module (ITBM) —
If Equipped 
Your vehicle may have an ITBM for electric and 
Electric Over Hydraulic (EOH) trailer brakes.
NOTE:This module has been designed and verified with 
electric trailer brakes and new EOH systems. 
Some previous EOH systems may not be 
compatible with ITBM.
Integrated Trailer Brake Module (ITBM)
 The user interface consists of the following:
GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control 
power output to the trailer brakes in 
0.5 increments. The GAIN setting can be increased 
to a maximum of 10 or decreased to a minimum of 
0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer brake 
control for the specific towing condition and should 
be changed as towing conditions change. Changes 
to towing conditions include trailer load, vehicle 
load, road conditions and weather.
Manual Brake Control Lever
Slide the manual brake control lever to the left to 
activate power to the trailer's electric brakes 
independent of the tow vehicle's brakes. If the 
manual brake control lever is activated while the 
brake is also applied, the greater of the two inputs 
determines the power sent to the trailer brakes.
The trailer and the vehicle’s stop lamps will come 
on when braking normally with the vehicle brake 
pedal. Only the trailer stop lamps will come on 
when the manual brake control lever is applied.
WARNING!
Do not connect trailer brakes to your vehicle's 
hydraulic brake lines. It can overload your 
brake system and cause it to fail. You might 
not have brakes when you need them and 
could have an accident.
Towing any trailer will increase your stopping 
distance. When towing, you should allow for 
additional space between your vehicle and the 
vehicle in front of you. Failure to do so could 
result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg) 
loaded, it should have its own brakes and they 
should be of adequate capacity. Failure to do 
this could lead to accelerated brake lining wear, 
higher brake pedal effort, and longer stopping 
distances.

8. In a traffic-free environment, tow the trailer on  a dry, level surface at a speed of 20–25 mph 
(30–40 km/h) and squeeze the manual brake 
control lever completely.
9. If the trailer wheels lockup (indicated by  squealing tires), reduce the GAIN setting; 
if the trailer wheels turn freely, increase the 
GAIN setting.
Repeat steps 8 and 9 until the GAIN setting is at a 
point just below trailer wheel lockup. If towing a 
heavier trailer, trailer wheel lockup may not be 
attainable even with the maximum GAIN setting
of 10.
*The suggested selection may change depending on the customer preferences for braking performance. Condition of the trailer brakes, driving and road state 
may also affect the selection.

instrument cluster display. Display messages, 
along with a single chime, will be displayed 
when a malfunction is determined in the trailer 
connection, trailer brake control, or on the trailer  
Ú page 114.
NOTE:
An aftermarket controller may be available for 
use with trailers with air or EOH trailer brake 
systems. To determine the type of brakes on 
your trailer and the availability of controllers, 
check with your trailer manufacturer or dealer.
Removal of the ITBM will cause errors and it 
may cause damage to the electrical system and 
electronic modules of the vehicle. See an autho -
rized dealer if an aftermarket module is to be 
installed.
Towing Requirements — Trailer Lights And 
Wiring
Whenever you pull a trailer, regardless of the trailer 
size, stop lights and turn signals on the trailer are 
required for motoring safety.
The Trailer Tow Package may include a four-pin 
and seven-pin wiring harness. Use a factory 
approved trailer harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring 
harness.
The electrical connections are all complete to the 
vehicle but you must connect the harness to a 
trailer connector. Refer to the following 
illustrations.
NOTE:
Disconnect trailer wiring connector from the 
vehicle before launching a boat (or any other 
device plugged into vehicle’s electrical connect) 
into water.
Be sure to reconnect once clear from water 
area.
Four-Pin Connector
WARNING!
Connecting a trailer that is not compatible with 
the ITBM system may result in reduced or 
complete loss of trailer braking. There may be a 
increase in stopping distance or trailer instability 
which could result in personal injury.
CAUTION!
Connecting a trailer that is not compatible with

STARTING AND OPERATING225
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 experience 
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  
Úpage 165. Selecting Tow/Haul or connecting a 
trailer with an Integrated Trailer Brake Module 
(ITBM) will disable Automatic Aero mode to avoid 
height changes while towing and shifting loads or 
tongue weights.
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 recom -
mended that the owner/installer obtain and follow 
the recommendations contained within the current 
Body Builder’s Guide. See an authorized dealer, 
installer or snowplow manufacturer for this infor -
mation. There are unique electrical systems that 
must be connected to properly ensure operator 
safety and prevent overloading vehicle systems.
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.

226STARTING 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 exces -
sive 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 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.
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.
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 overheating.
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.

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.
CAUTION!
Towing with the rear wheels on the ground will 
cause severe transmission damage. Damage 
from improper towing is not covered under the 
New Vehicle Limited Warranty.
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 transmission damage 
will result, if the transfer case is not in N 
(Neutral) during towing.
The transmission must be in PARK for recre -
ational towing.
Ensure that the Electric Park Brake is 
released, and remains released, while being 
towed.
Towing this vehicle in violation of the above 
requirements 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.
