engine braking when descending moderately steep
grades. To prevent excessive engine speed do not exceed
40 mph (64 km/h) in this range.
“2” Second
Use this position for driving on more severe conditions
and lower speeds than “3” third. To prevent excessive
engine speed do not exceed 25 mph (40 km/h) in this
range.
“1” First
Use this position for driving up very steep hills and for
engine braking at low speeds 15 mph (24 km/h) or less
when going downhill. To prevent excessive engine speed,
do not exceed 15 mph (24 km/h) in this range.
NOTE: Use caution when operating a heavily loaded
vehicle in “2” Second or “1” First gear selections in high
ambients as torque converter slip can impose significant
additional heat load on the cooling system. Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled 5th and 6th (if equipped) speed
(Overdrive). The transmission will automatically shift
from Drive to Overdrive if the following conditions are
present:
• the transmission selector is in Drive;
• the engine coolant has reached normal operating tem-
perature;
• vehicle speed is above approximately 38 mph (61
km/h) for 5th gear and 55 mph (89 km/h) for 6th gear;
• the “TOW HAUL O/D OFF” switch has not been
activated;
• transmission has reached normal operating tempera-
ture. STARTING AND OPERATING 275

When To Use “TOW HAUL” and “O/D OFF”
Modes
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the “TOW HAUL O/D OFF” button once to
select TOW HAUL. This will improve performance and reduce the potential for transmission overheating or
failure due to excessive shifting. When operating in
“TOW HAUL” mode, 6th gear (if equipped) is disabled
and 2-3 and 3-4 and 4–5 shift patterns are modified. Shifts
into Overdrive (5th gear) are allowed during steady
cruise (for improved fuel economy). Pressing the “TOW
HAUL O/D OFF” button a second time to select O/D
OFF will disable 5th and 6th gear completely, which
should eliminate any excessive transmission shifting.
The “TOW HAUL” or “O/D OFF” light will illuminate in
the instrument cluster to indicate when the switch has
been activated. Pressing the switch a third time restores
normal operation. If the “TOW HAUL” or “O/D OFF”
modes are desired, the button must be pressed each time
the engine is started.Tow Haul O/D Off Switch STARTING AND OPERATING 277

NOTE: If the vehicle has not been driven in several
days, the first few seconds of operation after shifting the
transmission into gear may seem sluggish. This is due to
the fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds of shifting from Park into
any other gear position.
MANUAL TRANSMISSION
WARNING!You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the
vehicle, especially on an incline. Truck models with manual transmission are equipped
with a clutch interlocking ignition system. The clutch
pedal must be fully depressed to start the vehicle.
Fully depress the clutch pedal before shifting gears. As
you release the clutch pedal, lightly depress the accelera-
tor pedal.
To shift into Reverse, come to a complete stop. Depress
the clutch and pause briefly to allow the gear train to
stop. Move the shift lever from the Neutral position
straight across and back into Reverse.
Never drive with your foot resting on the clutch pedal, or
attempt to hold the vehicle on a hill with the clutch pedal
partially engaged, as this will cause abnormal wear on
the clutch. STARTING AND OPERATING 279

Moving from a high gear down to a lower gear is
recommended to preserve brakes when driving down
steep hills. In addition, downshifting at the right time
provides better acceleration when you desire to resume
speed. For acceleration at speeds less than 20 mph (30
km/h), 2nd gear is recommended.
CAUTION!When descending a hill, be very careful to downshift
one gear at a time to prevent overspeeding the
engine which can cause valve damage.
To prevent clutch and transmission damage, your vehicle
should be downshifted at speeds no greater than those
listed in the Maximum Recommended Downshifting
Speed chart. STARTING AND OPERATING 281

FOUR-WHEEL- DRIVE OPERATION — IF
EQUIPPED
Four-Wheel-Drive Dodge Ram Trucks are equipped with
either a Manually Shifted transfer case or an Electroni-
cally Shifted transfer case. See the operating instructions
for your transfer case, located within this section. Manually Shifted Transfer Case Operating
Information/Precautions
The transfer case provides 4 mode position s-2(r ear)-
wheel-drive high range, 4-wheel-drive high range, neu-
tral, and 4-wheel-drive low range.
This transfer case is intended to be driven in the 2-wheel-
drive position (2H) for normal street and highway con-
ditions such as dry hard surfaced roads.
When additional traction is required the transfer case 4H
and 4L positions can be used to lock the front and rear
driveshafts together and force the front and rear wheels
to rotate at the same speed. This is accomplished by
simply moving the shift lever to the desired positions.
The 4H and 4L positions are intended for loose, slippery
road surfaces only. Driving in the 4H and 4L positions on
dry hard surfaced roads may cause increased tire wear
and damage to the driveline components. STARTING AND OPERATING 283

Snowplow Prep Package Model Availability
For Information about snowplow applications visit
www.dodge.com or refer to the current Dodge Body
Builders 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. The snowplow prep packages are not available with
the Sport Package.
4. 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 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 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. STARTING AND OPERATING 357

NOTE: Items 1 through 5 are requirements that must be
met prior to depressing the Neutral (N) selection button,
and must continue to be met until 1 second elapses and
the shift has been completed. If any of these requirements
(with the exception of 3 - key ON) are not met prior to
depressing the Neutral (N) button or are no longer met
during the 1 second time, then all of the mode position
indicator lights will flash continuously until all require-
ments are met or until the Neutral (N) button is released.
NOTE: The ignition key must be ON for a shift to take
place and for the position indicator lights to be operable.
If the key is not ON, the shift will not take place and no
position indicator lights will be on or flashing.
NOTE: Flashing neutral (N) position indicator light
indicates that shift requirements have not been met. WARNING!You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging the
parking brake. The transfer case Neutral (N) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
despite the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.366 STARTING AND OPERATING

VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
• Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Integrated Power Module, located in the
engine compartment. The I.O.D. cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
• The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
• As an alternative to the above steps you may, discon-
nect the negative cables from both batteries.
• Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
NOTE: When reinstalling the IOD fuse push firmly until
fully seated, the gages in the Instrument Cluster will do
a full sweep, when the ignition key is cycled to RUN. This
is a normal condition.
