2008 DODGE RAM 2500 DIESEL stop start

of the plow. Front end tow-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.
Methods For Removing Snow
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.

NOTE:During snowplow usage on vehicles equipped
with an overhead console module, the outside tempera-
ture display will show higher temperatures than the
outside ambient temperature. The higher displayed tem-
perature is due to blocked or reduced airflow to the
underhood ambient temperature sensor by the snow-
plow. This is common and outside temperature display
operation will return to normal when the snowplow is
removed.
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 driv-
etrain damage, the following precautions should be ob-
served.
²Operate with transfer case in 4L when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4H.
²Vehicles with 68RFE transmissions should use 4L
range when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
²Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission.

Recreational Towing Procedure Ð Manual Shift
Transfer Case Ð If Equipped
Use the following procedure to prepare your vehicle for
recreational towing:
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL before recre-
ational towing to prevent damage to internal parts.
1. Bring the vehicle to a complete stop.
2. Shut OFF the engine.
3. Depress the brake pedal.
4. Shift automatic transmission to NEUTRAL, or depress
the clutch on manual transmissions.5. Shift transfer case lever into NEUTRAL.
6. Start the engine.
7. Shift automatic transmission into REVERSE.
8. Release brake pedal for five seconds and ensure that
there is no vehicle movement.
9. Repeat steps 7 and 8 with the transmission in DRIVE.
10. Shut OFF the engine and place the ignition key in the
unlocked OFF position.
11. Shift automatic transmission into PARK or 1st gear
on manual transmissions.
12. Apply the parking brake.
13. Attach vehicle to tow vehicle with tow bar.
14. Release the parking brake.
376 STARTING AND OPERATING

CAUTION!
Damage to the automatic transmission may occur if
the transmission is shifted into PARK with the trans-
fer case in NEUTRAL and the engine running. With
the transfer case in NEUTRAL ensure that the engine
is OFF prior to shifting the transmission into PARK.
Returning to Normal Operation Ð Manual Shift
Transfer Case
Use the following procedure to prepare your vehicle for
normal usage:
1. Bring the vehicle to a complete stop.
2. Apply the parking brake.
3. Shut OFF the engine.
4. Depress the brake pedal.5. Shift automatic transmission to NEUTRAL, or depress
the clutch on manual transmissions.
6. Shift transfer case lever to desired position.
7. Shift automatic transmission into PARK.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move,
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.

CAUTION!
²Do not use a bumper-mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
²Do not disconnect the rear driveshaft because
fluid will leak from the transfer case and damage
the internal parts.
Recreational Towing Procedure Ð Electronic Shift

6. Using the point of a ballpoint pen or similar object,
depress the recessed transfer case NEUTRAL button for
four seconds.
378 STARTING AND OPERATING

CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into PARK with the transfer case in
NEUTRAL and the engine running. With the transfer
case in NEUTRAL ensure, that the engine is OFF
prior to shifting the transmission into PARK.
Returning to Normal Operation Ð Electronic Shift

380 STARTING AND OPERATING

Start the engine and operate it at idle for several minutes.
Check for leaks at the lubricating oil filter and oil pan
drain plug.
Run the engine until it has reached operating tempera-
ture, stop the engine. Wait approximately 15 minutes to
let the oil in the upper parts of the engine drain back to
the pan. Check the oil level again.
Add oil as necessary to bring the level to the ªSAFEº
mark on the dipstick.
Disposing Of Used Engine Oil And Filter
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station, or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Drive Belt
Inspection
Check the belt for intersecting cracks.
²Transverse (across the belt width) cracks are accept-
able.
²Longitudinal (direction of belt length) cracks that
intersect with transverse cracks are NOT acceptable.
Replace the belt if it has unacceptable cracks, is frayed or
has pieces of material missing.
The engine speed sensor, located near the damper, should
be inspected for damage if a belt is frayed.
