PROGRAMMING HOMELINK® TO A
M
ISCELLANEOUS DEVICE
The procedure on how to program HomeLink® to a
miscellaneous device follows the same procedure
as programming to a garage door opener
Ú page 51. Be sure to determine if the device has
a rolling code, or non-rolling code before beginning
the programming process.
NOTE:Canadian Radio Frequency (RF) laws require trans -
mitter signals to time-out (or quit) after several
seconds of transmission, which may not be long
enough for HomeLink® to pick up the signal during
programming. Similar to this Canadian law, some
U.S. gate operators are designed to time-out in the
same manner. The procedure may need to be
performed multiple times to successfully pair the
device to your HomeLink® buttons.
REPROGRAMMING A SINGLE
H
OMELINK® BUTTON
To reprogram a single HomeLink® button that has
been previously trained, without erasing all the
channels, follow the procedure below. Be sure to
determine whether the new device you want to
program the HomeLink® button to has a rolling
code, or non-rolling code.
1. Place the ignition in the ON/RUN position,
without starting the engine.

2. Push and hold the desired HomeLink® button until the HomeLink® indicator light begins to
flash after 20 seconds. Do not release the
button.
3. Without releasing the button , proceed with
Step 2 in “Programming HomeLink® To A
Garage Door Opener” Ú page 51, and follow
all remaining steps.
CANADIAN/GATE OPERATOR
P
ROGRAMMING
For programming transmitters in Canada/United
States that require the transmitter signals to
“time-out” after several seconds of transmission:
Canadian Radio Frequency (RF) laws require
transmitter signals to time-out (or quit) after
several seconds of transmission, which may not be
long enough for HomeLink® to pick up the signal
during programming. Similar to this Canadian law,
some U.S. gate operators are designed to time-out
in the same manner. It may be helpful to unplug the device during the
cycling process to prevent possible overheating of
the garage door or gate motor.

1. Place the ignition in the ON/RUN position.

NOTE:For vehicles equipped with Keyless Enter ‘n Go™,
place the ignition in the RUN position. Make sure
while programming HomeLink® with the engine on
that your vehicle is outside of your garage, or that
the garage door remains open at all times.
2. Place the hand-held transmitter 1 to 3 inches
(3 to 8 cm) away from the HomeLink® button
you wish to program while keeping the
HomeLink® indicator light in view.
3. Continue to push and hold the HomeLink® button while you push and release (cycle) your
hand-held transmitter every two seconds until
HomeLink® has successfully accepted the
frequency signal. The indicator light will flash
slowly and then rapidly when fully trained.
4. Watch for the HomeLink® indicator to change flash rates. When it changes, it is
programmed. It may take up to 30 seconds or
longer in rare cases. The garage door may
open and close while you are programming.

equipped.
OPERATING TIPS
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected with
a high-quality antifreeze coolant to provide proper
corrosion protection and to protect against engine
overheating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Ú page 461.
Window Fogging
Vehicle windows tend to fog on the inside in mild,
rainy, and/or humid weather. To clear the
windows, select Defrost or Mix mode and increase
the front blower speed. Do not use the
Recirculation mode without A/C for long periods,
as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of
the windshield, is free of obstructions, such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control system
may automatically adjust airflow to maintain cabin
comfort. Customer settings will be maintained
upon return to an engine running condition.

Four-Position/On-Demand Transfer Case

WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.
WARNING!
Do not use the TOW/HAUL feature when driving
in icy or slippery conditions. The increased
engine braking can cause the rear wheels to
slide, and the vehicle to swing around with the
possible loss of vehicle control, which may
cause an accident possibly resulting in personal
injury or death.

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.

Refueling Funnel

Emergency Gas Can Refueling:
Most gas cans will not open the flapper doors. A
funnel is provided to allow emergency refueling
with a gas can.
See below steps for refueling:

1. Retrieve funnel from the spare tire storage area.

2. Insert funnel into same filler pipe opening as the fuel nozzle.
Inserting Funnel

3. Ensure funnel is inserted fully to hold flapper doors open.
4. Pour fuel into funnel opening.
5. Remove funnel from filler pipe, clean off prior to putting back in the spare tire storage area.
IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be
serviced by an authorized dealer.
In any of the following situations, you can reduce
the potential for overheating by taking the
appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
WARNING!

390IN CASE OF EMERGENCY
NOTE: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 (N) for more than two seconds, you must
press the brake pedal to engage DRIVE or
REVERSE.
Push the ESC OFF button to place the Electronic
Stability Control (ESC) system in “Partial OFF”
mode, before rocking the vehicle Ú page 314.
Once the vehicle has been freed, push the ESC OFF
button to restore “ESC On” mode.TOWING A DISABLED VEHICLE
This section describes procedures for towing a
disabled vehicle using a commercial towing
service.
If the transmission and drivetrain are operable,
disabled vehicles may also be towed as described
on Ú page 227.
NOTE:
Vehicles equipped with the Active-Level Four
Corner Air Suspension System must be placed in
Transport mode, before tying them down (from the
body) on a trailer or flatbed truck Ú page 165. If
the vehicle cannot be placed in Transport mode
(for example, engine will not run), tie-downs must
be fastened to the axles (not to the body). Failure
to follow these instructions may cause fault codes
to be set and/or cause loss of proper tie-down
tension.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis -
sion failure during prolonged efforts to free a
stuck vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or
drivetrain damage may result.
Revving the engine or spinning the wheels too
fast may lead to transmission overheating and
failure. It can also damage the tires. Do not
spin the wheels above 30 mph (48 km/h)
while in gear (no transmission shifting occur -
ring).
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.
