128GETTING TO KNOW YOUR INSTRUMENT PANEL  
What to do when an electrical load reduction 
action message is present (“Battery Saver On” or 
“Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if possible:
Turn off redundant lights (interior or exte -
rior).
Check what may be plugged in to power 
outlets +12 Volts, 115 Volts AC, USB ports.
Check HVAC settings (blower, temperature).
Check the audio settings (volume).
After a trip:
Check if any aftermarket equipment was 
installed (additional lights, upfitter electrical 
accessories, audio systems, alarms) and review 
specifications if any (load and Ignition Off Draw 
currents).
Evaluate the latest driving cycles (distance, 
driving time and parking time).
The vehicle should have service performed if 
the message is still present during consecutive 
trips and the evaluation of the vehicle and 
driving pattern did not help to identify the cause.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the 
instrument panel together with a dedicated 
message and/or acoustic signal when applicable. 
These indications are indicative and precautionary 
and as such must not be considered as exhaustive 
and/or alternative to the information contained in 
the Owner’s Manual, which you are advised to read 
carefully in all cases. Always refer to the 
information in this chapter in the event of a failure 
indication. All active telltales will display first if 
applicable. The system check menu may appear 
different based upon equipment options and 
current vehicle status. Some telltales are optional 
and may not appear.
RED WARNING LIGHTS
Air Bag Warning Light 
This warning light will illuminate to 
indicate a fault with the air bag, and will 
turn on for four to eight seconds as a bulb 
check when the ignition is placed in the 
ON/RUN or ACC/ON/RUN position. This light will 
illuminate with a single chime when a fault with the 
air bag has been detected, it will stay on until the 
fault is cleared. If the light is either not on during 
startup, stays on, or turns on while driving, have 
the system inspected at an authorized dealer as 
soon as possible.
Brake Warning Light 
This warning light monitors various brake 
functions, including brake fluid level and 
parking brake application. If the brake 
light turns on it may indicate that the 
parking brake is applied, that the brake fluid level 
is low, or that there is a problem with the Anti-Lock 
Brake System reservoir.
If the light remains on when the parking brake has 
been disengaged, and the fluid level is at the full 
mark on the master cylinder reservoir, it indicates 
a possible brake hydraulic system malfunction or 
that a problem with the Brake Booster has been 
detected by the Anti-Lock Brake System (ABS) / 
Electronic Stability Control (ESC) system. In this 
case, the light will remain on until the condition has 
been corrected. If the problem is related to the 
brake booster, the ABS pump will run when 
applying the brake, and a brake pedal pulsation 
may be felt during each stop.
The dual brake system provides a reserve braking 
capacity in the event of a failure to a portion of the 
hydraulic system. A leak in either half of the dual 
brake system is indicated by the Brake Warning 
Light, which will turn on when the brake fluid level 
in the master cylinder has dropped below a 
specified level.
The light will remain on until the cause is corrected.

STARTING AND OPERATING211
3. Stop filling the DEF tank immediately when any  of the following happen: DEF stops flowing 
from the fill bottle into the DEF tank, DEF 
splashes out the filler neck, or a DEF pump 
nozzle automatically shuts off.
4. Reinstall cap onto DEF tank.
Filling The Def Tank In Cold Climates
Your vehicle is equipped with an automatic DEF 
heating system. This allows the DEF injection 
system to operate properly at temperatures below 
12°F (-11°C). If your vehicle is not in operation for 
an extended period of time with temperatures 
below 12°F (-11°C), the DEF in the tank may 
freeze. Do not overfill the DEF tank. If the tank is 
overfilled and freezes, it could be damaged.
Extra care should be taken when filling with 
portable containers to avoid overfilling. Keep an 
eye on the DEF gauge in your instrument cluster. 
You may safely add a maximum of 2 gallons
(7.6 Liters) when your DEF gauge is reading at 
the half mark.
VEHICLE LOADING   
GROSS VEHICLE WEIGHT RATING 
(GVWR) 
The GVWR is the total permissible weight of your 
vehicle including driver, passengers, vehicle, 
options and cargo. The label also specifies 
maximum capacities of front and rear Gross Axle 
Weight Rating (GAWR). Total load must be limited 
so GVWR and front and rear GAWR are not 
exceeded.
PAYLOAD
The payload of a vehicle is defined as the allowable 
load weight a truck can carry, including the weight 
of the driver, all passengers, options and cargo.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum permissible load on the 
front and rear axles. The load must be distributed 
in the cargo area so that the GAWR of each axle is 
not exceeded.
Each axle GAWR is determined by the components 
in the system with the lowest load carrying capacity 
(axle, springs, tires or wheels). Heavier axles or 
suspension components sometimes specified by 
purchasers for increased durability does not 
necessarily increase the vehicle's GVWR.
When DEF is spilled, clean the area immedi -
ately with water and use an absorbent mate -
rial to soak up the spills on the ground.
Do not attempt to start your engine if DEF is 
accidentally added to the diesel fuel tank as it 
can result in severe damage to your engine, 
including but not limited to failure of the fuel 
pump and injectors.
Never add anything other than DEF to the tank 
– especially any form of hydrocarbon such as 
diesel fuel, fuel system additives, gasoline, or 
any other petroleum-based product. Even a 
very small amount of these, less than 
100 parts per million or less than 1 oz. per 
78 gallons (295 liters) will contaminate the 
entire DEF system and will require replace -
ment. If owners use a container, funnel or 
nozzle when refilling the tank, it should either 
be new or one that has only been used for 
adding DEF. Mopar® provides an attachable 
nozzle with its DEF for this purpose.
CAUTION!

212STARTING AND OPERATING  
TIRE SIZE
The tire size on the Vehicle Certification Label 
represents the actual tire size on your vehicle. 
Replacement tires must be equal to the load 
capacity of this tire size.
RIM SIZE
This is the rim size that is appropriate for the tire 
size listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your 
vehicle for all loading conditions up to full Gross 
Axle Weight Rating (GAWR).
CURB WEIGHT
The curb weight of a vehicle is defined as the total 
weight of the vehicle with all fluids, including 
vehicle fuel, at full capacity conditions, and with no 
occupants or cargo loaded into the vehicle. The 
front and rear curb weight values are determined 
by weighing your vehicle on a commercial scale 
before any occupants or cargo are added.
LOADING
The actual total weight and the weight of the front 
and rear of your vehicle at the ground can best be 
determined by weighing it when it is loaded and 
ready for operation.
The entire vehicle should first be weighed on a 
commercial scale to insure that the Gross Vehicle 
Weight Rating (GVWR) has not been exceeded. The 
weight on the front and rear of the vehicle should 
then be determined separately to be sure that the 
load is properly distributed over the front and rear 
axle. Weighing the vehicle may show that the Gross 
Axle Weight Rating (GAWR) of either the front or 
rear axles has been exceeded but the total load is 
within the specified GVWR. If so, weight must be 
shifted from front to rear or rear to front as 
appropriate until the specified weight limitations 
are met. Store the heavier items down low and be 
sure that the weight is distributed equally. Stow all 
loose items securely before driving.
Improper weight distributions can have an adverse 
effect on the way your vehicle steers and handles 
and the way the brakes operate.
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.
CAUTION!
Do not load your vehicle any heavier than the 
GVWR or the maximum front and rear GAWR. If 
you do, parts on your vehicle can break, or it can 
change the way your vehicle handles. This could 
cause you to lose control. Also, overloading can 
shorten the life of your vehicle.
22_DT_OM_EN_USC_t.book  Page 212   

STARTING AND OPERATING213
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  Ú page 211.
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 211.
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.

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!
22_DT_OM_EN_USC_t.book  Page 220   

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.

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.
