STARTING AND OPERATING147
2H OR 4H TO 4L
NOTE:
When shifting into or out of 4L some gear noise
may be heard. This noise is normal and is not detri -
mental to the vehicle or occupants.
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h),
shift the transmission into NEUTRAL. While the
vehicle is coasting at 2 to 3 mph (3 to 5 km/h),
shift the transfer case lever firmly to the desired
position. Do not pause in transfer case Neutral.
NOTE:
Pausing in transfer case N (Neutral) in vehicles
equipped with an automatic transmission may
require shutting the engine OFF to avoid gear
clash while completing the shift. If difficulty
occurs, shift the transmission into Neutral, hold
your foot on the brake, and turn the engine OFF.
Complete the range shift to the desired position.

Shifting into or out of 4L is possible with the
vehicle completely stopped, however difficulty
may occur due to the mating teeth not being prop -
erly aligned. Several attempts may be required for
teeth alignment and shift completion to occur.
The preferred method is with the vehicle rolling 2
to 3 mph (3 to 5 km/h). Avoid attempting to
engage or disengage 4L with the vehicle moving
faster than 2 to 3 mph (3 to 5 km/h).

Do not attempt to shift into or out of 4L while the
transmission is in gear.
Transfer Case Position Indicator Light
The Transfer Case Position Indicator Light in the
instrument cluster is used to alert the driver that
the front axle is fully engaged and all four wheels
are driving.
LIMITED-SLIP DIFFERENTIAL
The limited-slip differential provides additional
traction on snow, ice, mud, sand and gravel,
particularly when there is a difference between the
traction characteristics of the surface under the
right and left rear wheels. During normal driving
and cornering, the limited-slip unit performs
similarly to a conventional differential. On slippery
surfaces, however, the differential delivers more of
the driving effort to the rear wheel having the
better traction.
The limited-slip differential is especially helpful
during slippery driving conditions. With both rear
wheels on a slippery surface, a slight application of
the accelerator will supply maximum traction.
When starting with only one rear wheel on an
excessively slippery surface, slight momentary
application of the parking brake may be necessary
to gain maximum traction. Care should be taken to avoid sudden
accelerations when both rear wheels are on a
slippery surface. This could cause both rear wheels
to spin, and allow the vehicle to slide sideways on
the crowned surface of a road or in a turn.
POWER TAKE OFF (PTO) OPERATION —
IF EQUIPPED
This vehicle when equipped with PTO Prep and the
AS66RC/AS69RC automatic 6-speed, will allow for
an aftermarket upfit with a transmission driven
PTO. The customer will have the ability to operate
the PTO in either a “stationary”, “mobile” or
“remote” mode. The vehicles will be factory set to
the “stationary” mode. To select a different mode,
or to change any other PTO setting, you will need to
enter the commercial vehicle menu on the
instrument cluster screen. Details of the PTO
selection modes and further PTO information is
available at the Ram Truck Body Builder’s web site:

body-builders-guide.html
WARNING!
On vehicles equipped with a limited-slip
differential never run the engine with one rear
wheel off the ground since the vehicle may drive
through the rear wheel remaining on the ground.
You could lose control of the vehicle.

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 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 Rating (GVWR) or
Gross Axle Weight Rating (GAWR). 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.
