Electronic Speed Control — If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed. Air Conditioning
Turn off temporarily.
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
recommended that the owner/installer obtain and follow
the recommendations contained within the current Ram
Body Builders Guide. See your authorized dealer, in-
staller or snowplow manufacturer for this information.
There are unique electrical systems that must be con-
nected to properly assure operator safety and prevent
overloading vehicle systems.524 STARTING AND OPERATING
Page 528 of 675

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 Com-
pliance Certification Label on the driver’s side door
opening.
NOTE: Detach the snowplow when transporting pas-
sengers.
Vehicle front end wheel alignment was set to specifica-
tions 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 equip-
ment following the recommendations provided by the
specific snowplow manufacturer.
Over The Road Operation With Snowplow
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.526 STARTING AND OPERATING
Page 529 of 675
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 drive-
train damage, the following precautions should be ob-
served. • Operate with transfer case in 4LO when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4HI.
• Vehicles with automatic transmissions should use 4LO
range 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. 5STARTING AND OPERATING 527
Page 533 of 675

CAUTION! (Continued)• Do not disconnect the rear driveshaft because fluid
will leak from the transfer case, causing damage to
internal parts.
• Do not use a bumper-mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for
recreational towing.
WARNING!You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging (Continued) WARNING! (Continued)the parking brake. The transfer case NEUTRAL (N)
position disengages both the front and rear drive
shaft from the powertrain, and will allow the vehicle
to roll, even if the automatic transmission is in PARK
(or manual transmission is in gear). The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal
parts.
1. Bring the vehicle to a complete stop, with the engine
running. Firmly apply the parking brake. 5STARTING AND OPERATING 531
Page 534 of 675

2. Shift the transmission to NEUTRAL.
3. Press and hold the brake pedal.
4. Depress the clutch pedal on a manual transmission.
5. Shift the transfer case into NEUTRAL:
• With manual shift transfer case, shift the transfer
case lever into NEUTRAL (N).
• With electronic shift transfer case, push and hold the
transfer case NEUTRAL (N) button. Some models
have a small, recessed N button (at the center of the
transfer case switches) that must be pressed using a
ballpoint pen or similar object. Other models have a
rectangular NEUTRAL switch, below the rotary
transfer case control knob. The NEUTRAL (N) indi-
cator light will blink while the shift is in progress.
The light will stop blinking (stay on solid) when the
shift to NEUTRAL (N) is complete. After the shift is
completed and the NEUTRAL (N) light stays on,
release the NEUTRAL (N) button. 6. Release the parking brake.
7. Shift the transmission into REVERSE.
8. Release the brake pedal (and clutch pedal on manual
transmissions) for five seconds and ensure that there is
no vehicle movement.
9. Repeat steps 7 and 8 with automatic transmission in
DRIVE or manual transmission in first gear.
10. 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 EN-
GINE START/STOP button until the engine shuts off.
11. Shift the transmission into PARK or place manual
transmission in gear (NOT in NEUTRAL).
12. Turn the ignition switch to the OFF position, and
remove the Key Fob.532 STARTING AND OPERATING
Page 535 of 675

13. Attach the vehicle to the tow vehicle using a suitable
tow bar.
14. Release the parking brake.
NOTE: With electronic shift transfer case:
• Steps 2 through 5 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 push-
ing 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 switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing. • A flashing NEUTRAL (N) position indicator light
indicates that shift requirements have not been met.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Bring the vehicle to a complete stop, leaving it con-
nected to the tow vehicle.
2. Firmly apply the parking brake.
3. Turn the ignition switch to the ON/RUN position, but
do not start the engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
• With manual shift transfer case, shift the transfer
case lever to the desired position. 5STARTING AND OPERATING 533
