considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the operation of a cellular
phone in your vehicle can cause erratic or noisy perfor-
mance from your radio. This condition may be lessened
or eliminated by relocating the cellular phone antenna.
This condition is not harmful to the radio. If your radio
performance does not satisfactorily “clear” by the repo-
sitioning of the antenna, it is recommended that the radio
volume be turned down or off during cellular phone
operation.
CLIMATE CONTROLS
The controls for the heating and ventilation system in this
vehicle consist of a series of rotary knobs. These comfort
controls can be set to obtain desired interior conditions.

Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases
turning on the Air-conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using MIX Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. Higher blower
speeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.

Block Heater Usage
A.Temperatures below 0°F (-18°C)
•Block Heater Required for 15W-40
•Block Heater Recommended for 5W-40
B. Temperatures below - 20°F (-29°C)
•Block Heater Required for 5W-40
Winter Front Usage
If a winter front or cold weather cover is to be used, a
percentage of the total grille opening area must be left
uncovered to provide sufficient air flow to the charge air
cooler and automatic transmission oil cooler. The per-
centage of opening must be increased with the increasing
ambient air temperature and/or engine load. If the
cooling fan can be heard cycling frequently, increase the
size of the opening in the winter front. A suitable cold
weather cover is available from your Mopar dealer.
Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized Mopar dealer.
Arctic Operation
Where there are no provisions to keep the engine warm
when it is operating in ambient temperatures consistently
below (-10°F/-23°C), use 5W-40 syntheticengine oil and
fuel that meets the requirements in Section 7, “Mainte-
nance Procedures,” Engine Oil Selection.
262 STARTING AND OPERATING

The alarm will continue for 3 minutes if the driver’s door
is closed but none of the other conditions listed above are
met.
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.
This transmission has a “creeper” 1st gear which should
be used to start from a standing position when carrying
a payload or towing a trailer. Damage to the clutch can
result from starting in 2nd or 3rd gear with a loaded
vehicle. An unloaded vehicle may be launched in 2nd
gear. Use each gear in numerical order – do not skip a
gear.
For most city driving you may find it easier to use only
1st through 5th gear ranges. For steady highway driving
with light accelerations, 6th gear is recommended. To
shift into 5th gear, move the shift lever to the right
beyond the spring pressure point and push it forward.
When shifting from 5th to 4th gear, pull the lever down
274 STARTING AND OPERATING

toward you in one motion. Do not pull the lever sharply
left as you may shift accidentally into 2nd gear and
damage the transmission.
You should use 1st gear when starting from a standing
position if under heavy load or when pulling a trailer.
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.Downshifting
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. Downshift progressively. Do not skip gears to
avoid overspeeding the engine and clutch. For accelera-
tion at speeds less than 15 mph (25 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

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.
