A/C Button
Push the A/C button to engage the Air 
Conditioning (A/C). The A/C indicator 
illuminates when A/C is on.
NOTE:
For Manual Climate Controls, if the system is in 
Mix, Floor or Defrost mode, the A/C can be 
turned off, but the A/C system shall remain 
active to prevent fogging of the windows.
If fog or mist appears on the windshield or side 
glass, select Defrost mode, and increase blower 
speed if needed.
If your air conditioning performance seems 
lower than expected, check the front of the A/C 
condenser (located in front of the radiator), for 
an accumulation of dirt or insects. Clean with a 
gentle water spray from the front of the radiator 
and through the condenser.
Recirculation Button
Push the Recirculation button to change 
the system between recirculation mode 
and outside air mode. The Recirculation 
indicator and the A/C indicator illuminate 
when the Recirculation button is pressed. 
Recirculation can be used when outside 
conditions, such as smoke, odors, dust, or 
humidity are present. Recirculation can be used in 
all modes except for Defrost. Recirculation may be 
unavailable if conditions exist that could create  fogging on the inside of the windshield. The A/C 
can be deselected manually without disturbing the 
mode control selection. Continuous use of the 
Recirculation mode may make the inside air stuffy 
and window fogging may occur. Extended use of 
this mode is not recommended.
On systems with Manual Climate Controls, the 
Recirculation mode is not allowed in Defrost mode 
to improve window cleaning operation. 
Recirculation is disabled automatically if this mode 
is selected. Attempting to use Recirculation while 
in this mode causes the LED in the control button 
to blink and then turn off.
Front Defrost Setting
Turn the mode control knob to the Front 
Defrost mode setting. Air comes from the 
windshield and side window demist 
outlets. When the defrost button is 
selected, the blower level may increase. Use 
Defrost mode with maximum temperature settings 
for best windshield and side window defrosting 
and defogging.
Rear Defrost Button
Push and release the Rear Defrost 
Control button to turn on the rear window 
defroster and the heated outside mirrors 
(if equipped). The Rear Defrost indicator 
illuminates when the rear window defroster is on.  The rear window defroster automatically turns off 
after 10 minutes.
Temperature Control
Temperature Control regulates the temperature of 
the air forced through the climate system.
The temperature increases as you 
turn the temperature control knob 
clockwise.
The temperature decreases as you
turn the temperature control knob 
counterclockwise.
CAUTION!
Failure to follow these cautions can cause 
damage to the heating elements:
Use care when washing the inside of the rear 
window. Do not use abrasive window cleaners 
on the interior surface of the window. Use a 
soft cloth and a mild washing solution, wiping 
parallel to the heating elements. Labels can 
be peeled off after soaking with warm water.
Do not use scrapers, sharp instruments, or 
abrasive window cleaners on the interior 
surface of the window.
Keep all objects a safe distance from the 
window.

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.
22_DT_OM_EN_USC_t.book  Page 226   

232STARTING AND OPERATING  
OFF-ROAD DRIVING TIPS  
Care should be taken when attempting to climb 
steep hills or driving diagonally across a hill or 
slope. If natural obstacles force you to travel 
diagonally up or down a hill, choose a mild angle 
and keep as little side tilt as possible. Keep the 
vehicle moving and make turns slowly and 
cautiously.
If you must back down a hill, back straight down 
using REVERSE gear. Never back down in 
NEUTRAL or diagonally across the hill.
When driving over sand, mud, and other soft 
terrain, shift to low gear and drive steadily. Apply 
the accelerator slowly to avoid spinning the 
wheels.
Do not reduce the tire pressures for this type of 
driving.
After Driving Off-Road
Off-road operation puts more stress on your 
vehicle than does most on-road driving. After going 
off-road, it is always a good idea to check for 
damage. That way you can get any problems taken 
care of right away and have your vehicle ready 
when you need it.
Completely inspect the underbody of your 
vehicle. Check tires, body structure, steering, 
suspension, and exhaust system for damage.
Inspect the radiator for mud and debris and 
clean as required.
Check threaded fasteners for looseness, partic -
ularly on the chassis, drivetrain components, 
steering, and suspension. Retighten them, if 
required, and torque to the values specified in 
the Service Manual.
Check for accumulations of plants or brush. 
These things could be a fire hazard. They might 
hide damage to fuel lines, brake hoses, axle 
pinion seals, and propeller shafts.
After extended operation in mud, sand, water, or 
similar dirty conditions, have the radiator, fan, 
brake rotors, wheels, brake linings, and axle 
yokes inspected and cleaned as soon as 
possible.
If you experience unusual vibration after driving 
in mud, slush or similar conditions, check the 
wheels for impacted material. Impacted mate -
rial can cause a wheel imbalance and freeing 
the wheels of it will correct the situation.
WARNING!
Abrasive material in any part of the brakes may 
cause excessive wear or unpredictable braking. 
You might not have full braking power when you 
need it to prevent a collision. If you have been 
operating your vehicle in dirty conditions, get 
your brakes checked and cleaned as necessary.

IN CASE OF EMERGENCY385
Positive (+) Battery Post Location
NOTE:The positive battery post may be covered with a 
protective cap. Lift up on the cap to gain access to 
the positive battery post. Do not jump off fuses. 
Only jump directly off positive post which has a 
positive  (+) symbol on or around the post.
Follow the below steps to prepare for jump 
starting:
1. Shift the automatic transmission into PARK,  apply the parking brake and turn the ignition 
OFF.
2. Turn off the heater, radio, and all electrical  accessories. 3. If using another vehicle to jump start the 
battery, park the vehicle within the jumper 
cables’ reach, apply the parking brake and 
make sure the ignition is OFF.
4. Pull upward and remove the protective cover  over the positive  (+) battery post.
JUMP STARTING PROCEDURE
Connecting The Jumper Cables
1. Connect the positive 
 (+) end of the jumper 
cable to the positive  (+)
 post of the discharged 
vehicle.
NOTE:Do not jump off fuses. Only jump directly off 
positive post.
2. Connect the opposite end of the positive  (+) 
jumper cable to the positive  (+) post of the 
booster battery.
WARNING!
Do not allow vehicles to touch each other as this 
could establish a ground connection and 
personal injury could result.
WARNING!
Take care to avoid the radiator cooling fan 
whenever the hood is raised. It can start 
anytime the ignition switch is ON. You can be 
injured by moving fan blades.
Remove any metal jewelry such as rings, 
watch bands and bracelets that could make 
an inadvertent electrical contact. You could be 
seriously injured.
Batteries contain sulfuric acid that can burn 
your skin or eyes and generate hydrogen gas 
which is flammable and explosive. Keep open 
flames or sparks away from the battery.
WARNING!
Failure to follow this jump starting procedure 
could result in personal injury or property 
damage due to battery explosion.
CAUTION!
Failure to follow these procedures could result in 
damage to the charging system of the booster 
vehicle or the discharged vehicle.

388IN CASE OF EMERGENCY  
NOTE:There are steps that you can take to slow down an 
impending overheat condition: 
If your Air Conditioner (A/C) is on, turn it off. The 
A/C system adds heat to the engine cooling 
system and turning the A/C off can help remove 
this heat.
You can also turn the temperature control to 
maximum heat, the mode control to floor and 
the blower control to high. This allows the heater 
core to act as a supplement to the radiator and 
aids in removing heat from the engine cooling 
system.
MANUAL PARK RELEASE
In order to move the vehicle in cases where the 
transmission will not shift out of PARK (P) (such as 
a depleted battery), a Manual Park Release is 
available.
Follow these steps to activate the Manual Park 
Release:
1. Apply firm pressure to the brake pedal while 
seated in the driver’s seat.
2. Apply the parking brake if possible.
3. Using a small screwdriver or similar tool, open  the Manual Park Release cover, which is 
located to the lower left of the steering column.
Manual Park Release Access Cover
WARNING!
You or others can be badly burned by hot engine 
coolant (antifreeze) or steam from your radiator. 
If you see or hear steam coming from under the 
hood, do not open the hood until the radiator 
has had time to cool. Never try to open a cooling 
system pressure cap when the radiator or 
coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage 
your vehicle. If the temperature gauge reads 
HOT (H), pull over and stop the vehicle. Idle the 
vehicle with the air conditioner turned off until 
the pointer drops back into the normal range. If 
the pointer remains on HOT (H), and you hear 
continuous chimes, turn the engine off 
immediately and call for service.
WARNING!
Always secure your vehicle by fully applying the 
parking brake before activating the Manual Park 
Release. In addition, you should be seated in the 
driver’s seat with your foot firmly on the brake 
pedal when activating the Manual Park Release. 
Activating the Manual Park Release will allow 
your vehicle to roll away if it is not secured by the 
parking brake, or by proper connection to a tow 
vehicle. Activating the Manual Park Release on 
an unsecured vehicle could lead to serious 
injury or death for those in or around the vehicle.

SERVICING AND MAINTENANCE407
CHECKING OIL LEVEL
To ensure proper engine lubrication, the engine oil 
must be maintained at the correct level. Check the 
oil level at regular intervals, such as every fuel 
stop. The best time to check the engine oil level is 
about five minutes after a fully warmed up engine 
is shut off.
Checking the oil while the vehicle is on level ground 
will improve the accuracy of the oil level readings.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the low 
end of the range and MAX at the high end of the 
range.
Crosshatched zone marked with dimples at the 
MIN and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch 
markings on the dipstick.
Adding 1 quart (1.0 liter) of oil when the reading is 
at the low end of the dipstick range will raise the oil 
level to the high end of the range marking.
ADDING WASHER FLUID  
The fluid reservoir is located under the hood and 
should be checked for fluid level at regular 
intervals. Fill the reservoir with windshield washer 
solvent only (not radiator antifreeze). When 
refilling the washer fluid reservoir, take some 
washer fluid and apply it to a cloth or towel and 
wipe the wiper blades clean. This will help blade 
performance.
To prevent freeze-up of your windshield washer 
system in cold weather, select a solution or mixture 
that meets or exceeds the temperature range of 
your climate. This rating information can be found 
on most washer fluid containers. After the engine has warmed up, operate the 
defroster for a few minutes to reduce the 
possibility of smearing or freezing the fluid on the 
cold windshield. Windshield washer solution used 
with water as directed on the container, aids 
cleaning action, reduces the freezing point to avoid 
line clogging, and is not harmful to paint or trim.
CAUTION!
Overfilling or underfilling the crankcase will 
cause oil aeration or loss of oil pressure. This 
could damage your engine.
WARNING!
Commercially available windshield washer 
solvents are flammable. They could ignite and 
burn you. Care must be exercised when filling or 
working around the washer solution.

418SERVICING AND MAINTENANCE  
ACCESSORY DRIVE BELT INSPECTION
When inspecting accessory drive belts, small 
cracks that run across the ribbed surface of the 
belt from rib to rib, are considered normal. This is 
not a reason to replace the belt. However, cracks 
running along a rib (not across) are not normal. Any 
belt with cracks running along a rib must be 
replaced. Also have the belt replaced if it has 
excessive wear, frayed cords or severe glazing.
 Accessory Belt (Serpentine Belt)
Conditions that would require replacement:
Rib chunking (one or more ribs has separated 
from belt body)
Rib or belt wear
Longitudinal belt cracking (cracks between two 
ribs)
Belt slips
“Groove jumping" (belt does not maintain 
correct position on pulley)
Belt broken
Noise (objectionable squeal, squeak, or rumble 
is heard or felt while drive belt is in operation)
NOTE:Identify and correct problem before new belt is 
installed.
NOTE:If your vehicle is equipped with a Stop/Start, belt 
must be replaced with an OEM grade Mopar® belt.
Some conditions can be caused by a faulty 
component such as a belt pulley. Belt pulleys 
should be carefully inspected for damage and 
proper alignment.
Belt replacement on some models requires the 
use of special tools, we recommend having your 
vehicle serviced at an authorized dealer.
BODY LUBRICATION  
Locks and all body pivot points, including such 
items as seat tracks, door hinge pivot points and 
rollers, liftgate, tailgate, decklid, sliding doors and 
hood hinges, should be lubricated periodically. Use 
a lithium-based grease, such as Mopar® Spray 
White Lube to assure quiet, easy operation and to 
protect against rust and wear. Prior to the 
application of any lubricant, the parts concerned 
should be wiped clean to remove dust and grit; 
after lubricating excess oil and grease should be 
removed. Particular attention should also be given 
to hood latching components to ensure proper 
function. When performing other underhood 
services, the hood latch release mechanism, and 
safety catch should be cleaned and lubricated.
WARNING!
Do not attempt to inspect an accessory drive 
belt with vehicle running.
When working near the radiator cooling fan, 
disconnect the fan motor lead. The fan is 
temperature controlled and can start at any 
time regardless of ignition mode. You could be 
injured by the moving fan blades.
You can be badly injured working on or around 
a motor vehicle. Only do service work for which 
you have the knowledge and the proper equip -
ment. If you have any doubt about your ability 
to perform a service job, take your vehicle to a 
competent mechanic.

SERVICING AND MAINTENANCE421
(Continued)
Under normal operating conditions, the catalytic 
converter will not require maintenance. However, it 
is important to keep the engine properly tuned to 
assure proper catalyst operation and prevent 
possible catalyst damage.
NOTE:Intentional tampering with emissions control 
systems can result in civil penalties being 
assessed against you.
In unusual situations involving grossly 
malfunctioning engine operation, a scorching odor 
may suggest severe and abnormal catalyst 
overheating. If this occurs, stop the vehicle, turn off 
the engine and allow it to cool. Service, including a 
tune-up to manufacturer's specifications, should 
be obtained immediately. To minimize the possibility of catalytic converter 
damage:
Do not interrupt the ignition when the transmis
-
sion is in gear and the vehicle is in motion.
Do not try to start the vehicle by pushing or 
towing the vehicle.
Do not idle the engine with any ignition compo -
nents disconnected or removed, such as when 
diagnostic testing, or for prolonged periods 
during very rough idle or malfunctioning oper -
ating conditions.
COOLING SYSTEM 
Engine Coolant Checks 
Check the engine coolant (antifreeze) protection 
every 12 months (before the onset of freezing 
weather, where applicable). If the engine coolant is 
dirty or rusty in appearance, the system should be 
drained, flushed and refilled with fresh coolant. 
Check the front of the A/C condenser (if equipped) 
or radiator for any accumulation of bugs, leaves, 
etc. If dirty, clean by gently spraying water from a 
garden hose vertically down the face of the A/C 
condenser (if equipped) or the back of the radiator 
core.
Check the engine cooling system hoses for brittle 
rubber, cracking, tears, cuts and tightness of the 
connection at the coolant recovery bottle and 
radiator. Inspect the entire system for leaks.
DO NOT REMOVE THE COOLANT PRESSURE CAP 
WHEN THE COOLING SYSTEM IS HOT. 
Damage to the catalytic converter can result if 
your vehicle is not kept in proper operating 
condition. In the event of engine malfunction, 
particularly involving engine misfire or other 
apparent loss of performance, have your 
vehicle serviced promptly. Continued opera -
tion of your vehicle with a severe malfunction 
could cause the converter to overheat, 
resulting in possible damage to the converter 
and vehicle.
CAUTION!
WARNING!
You or others can be badly burned by hot 
engine coolant (antifreeze) or steam from your 
radiator. If you see or hear steam coming from 
under the hood, do not open the hood until the 
radiator has had time to cool. Never open a 
cooling system pressure cap when the radi -
ator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry away 
from the radiator cooling fan when the hood is 
raised. The fan starts automatically and may 
start at any time, whether the engine is 
running or not.
When working near the radiator cooling fan, 
disconnect the fan motor lead or turn the igni -
tion to the OFF mode. The fan is temperature 
controlled and can start at any time the igni -
tion is in the ON mode.
WARNING!
