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 isencountered, 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.
NOTE:On models equipped with Diesel engines, the
idle speed will automatically increase to 1000 rpm at
elevated coolant temperatures to improve engine cooling.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.

When To Use ªTOW/HAULº Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the ªTOW/HAULº button. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in ªTOW/HAULº mode, 5th gear (ifequipped) is disabled and 2-3 and 3-4 shift patterns are
modified. Shifts into Overdrive (4th gear) are allowed
during steady cruise (for improved fuel economy) and
automatic closed-throttle downshifts to 3rd gear (for
improved braking) will occur during steady braking.
The ªTOW/HAULº light will illuminate in the instru-
ment cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the ªTOW/HAULº mode is desired,
the button must be pressed each time the engine is
started.
Torque Converter Clutch
A feature, designed to improve fuel economy, has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in

Manual Transmission ± 5±Speed (NV4500)
2500 and 3500 models are equipped with the NV4500
manual transmission. This transmission has a ªcreeperº
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 4th gear
ranges. For steady highway driving
with light accelerations, 5th gear is rec-
ommended. 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 toward you in
one motion. Do not pull the lever sharply left as you may
shift accidentally into 2nd gear and damage the trans-
mission.
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.

Electronically Shifted Transfer Case Operating
Information/Precautions
This is an electric shift transfer case and is operated by
the 4WD Control Switch (Transfer Case Switch), which is
located on the instrument panel.
The Electronically Shifted transfer case provides 4 mode
positions: 2 (rear) wheel drive high range or all wheel
drive high range, 4 wheel drive high range, 4 wheel drive
low range, and neutral.
The Electronically Shifted transfer case is designed to be
driven in the 2 wheel drive position (2WD) or all wheel
drive position (AWD) for normal street and highway
conditions (dry hard surfaced roads).
When additional traction is required, the transfer case
4HI and 4LO positions can be used to lock the front andrear driveshafts together and force the front and rear
wheels to rotate at the same speed. This is accomplished
by rotating the 4WD Control Switch to the desired
position - see Shifting Procedure section for specific
shifting instructions. The 4HI and 4LO positions are
designed for loose, slippery road surfaces only. Driving
in the 4HI and 4LO positions on dry hard surfaced roads
may cause increased tire wear and damage to the driv-
eline components.
NOTE:The transfer case Neutral (N) position is selected
by depressing the recessed button located on the lower
left hand corner of the 4WD Control Switch. The transfer
case Neutral (N) position is to be used for recreational
towing only. See the Recreational Towing section for
specific procedures on shifting into and out of Neutral
(N).

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
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
For additional information on the appropriate use of each
transfer case mode position see the information below:
