SNOWPLOW
2500/3500 Models Only
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 recommenda -
tions contained within the current Body Builders Guide. See
your authorized dealer, installer or snowplow manufacturer
for this information. There are unique electrical systems that
must be connected to properly assure operator safety and
prevent overloading vehicle systems. 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 in (6 cm to 1.2 cm) above
ground in snow plowing position.
• Check that snowplow lighting is connected and func -
tioning properly.
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.

Guide.
1. The maximum number of occupants in the truck shouldnot exceed two.
2. The total GVWR or the 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 neces
-
sary 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 equip -
ment following the recommendations provided by the
specific snowplow manufacturer.

434 STARTING AND OPERATING
7. Release the brake pedal for five seconds and ensure thatthere is no vehicle movement.
8. Repeat steps 6 and 7 with automatic transmission in DRIVE.
9. Shift the transmission to NEUTRAL. Firmly 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.
10. Shift the transmission into PARK. On 8-speed transmis -
sions the shifter will automatically select PARK when the
engine is turned off.
11. Turn the ignition to the OFF mode, then cycle the ignition to the RUN mode and back to the OFF mode. Remove the
key fob from the ignition.
12. Attach the vehicle to the tow vehicle using a suitable tow bar.
13. Release the parking brake. NOTE:
With electronic shift transfer case:
• Steps 2 through 3 are requirements that must be met before
pushing the NEUTRAL (N) button, and must continue to
be met until the shift has been completed. If any of these
requirements are not met before pushing the NEUTRAL
(N) button or are no longer met during the shift, the
NEUTRAL (N) indicator light will flash continuously until
all requirements are met or until the NEUTRAL (N) 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 oper -
able. 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 NEUTRAL (N) position indicator light indi -
cates that shift requirements have not been met.
• If the vehicle is equipped with air suspension, the engine should be started and left running for a minimum of 60
seconds (with all the doors closed) at least once every 24
hours. This process allows the air suspension to adjust the
vehicle’s ride height to compensate for temperature
effects.

SOS Call System Limitations
Vehicles sold in Mexico DO NOT have SOS Call system
capabilities.
SOS or other emergency line operators in Mexico may not
answer or respond to SOS system calls.
If the SOS Call system detects a malfunction, any of the
following may occur at the time the malfunction is detected,
and at the beginning of each ignition cycle:
• The overhead console light located between the ASSIST and SOS buttons will continuously be illuminated red.
• The Device Screen will display the following message: “Vehicle device requires service. Please contact your
dealer.”
• An In-Vehicle Audio message will state “Vehicle device requires service. Please contact your dealer.” Even if the SOS Call system is fully functional, factors
beyond FCA US LLC’s control may prevent or stop the SOS
Call system operation. These include, but are not limited to,
the following factors:
• Delayed accessories mode is active.
• The ignition is in the OFF position.
• The vehicle’s electrical systems are not intact.
• The SOS Call system software and/or hardware are
damaged during a crash.
• The vehicle battery loses power or becomes disconnected during a vehicle crash.

Hub Caps/Wheel Covers — If Equipped
The hub caps must be removed before raising the vehicle off
the ground.
For 2500/3500 single rear wheel (SRW) models, use the flat
end of the lug wrench to hook and pull off the hub cap. Find
the opening in the hub cap, insert the lug wrench, and pull
off the cap. If you need to pry against the wheel, protect the
wheel surface.Lug Wrench Insertion Location — Hub Cap
On 3500 models with dual rear wheels (DRW), you must first
remove the hub caps—use the procedure noted for the single
rear wheel. For the wheel covers (wheel skins), insert the flat
end of the lug wrench between the outer edge of the wheel
cover and the wheel. Pry against the wheel to remove the
wheel cover. Repeat this procedure around the wheel until
the cover pops off.

494 IN CASE OF EMERGENCY
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front wheels.
Then shift back and forth between DRIVE and REVERSE,
while gently pressing the accelerator. Use the least amount ofaccelerator pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing the engine.
NOTE:
• For trucks equipped with an 8–speed transmission, shifts
between DRIVE and REVERSE can only be achieved at
wheel speeds of 5 mph (8 km/h) or less. Whenever the
transmission remains in NEUTRAL for more than two
seconds, you must press the brake pedal to engage DRIVE
or REVERSE.
• Push the "ESC Off" switch, to place the Electronic Stability Control (ESC) system in "Partial Off" mode, before rocking
the vehicle. Refer to “Electronic Brake Control” in “Safety”
for further information. Once the vehicle has been freed,
push the "ESC Off" switch again to restore "ESC On" mode.
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!

Fast spinning tires can be dangerous. Forces generated by
excessive wheel speeds may cause damage, or even failure,
of the axle and tires. A tire could explode and injure
someone. Do not spin your vehicle's wheels faster than
30 mph (48 km/h) or for longer than 30 seconds continuously
without stopping when you are stuck and do not let anyone
near a spinning wheel, no matter what the speed.
