accelerator pedal may be required after shifting. This will
induce a torque interrupt and allow full engagement of
the newly selected position. With the vehicle stationary it
may be necessary to shift the automatic transmission
from D (Drive) to R (Reverse) and back to D (Drive) after
shifting. This will allow full engagement of the newly
selected position. Apply a constant force when shifting
the transfer case lever.
4 PART TIME to 4 FULL TIME or 4 FULL TIME to
4 PART TIME
Shifting between 4 PART TIME and 4 FULL TIME can be
made with the vehicle stopped or in motion. If the vehicle
is in motion shifts can be made up to 55 mph (88 km/h).
With the vehicle in motion two momentary releases of the
accelerator pedal may be required after shifting. This will
induce a torque interrupt and allow full engagement of
the newly selected position. With the vehicle stationary it
may be necessary to shift the automatic transmission
from D (Drive) to R (Reverse) and back to D (Drive) aftershifting. This will allow full engagement of the newly
selected position. Apply a constant force when shifting
the transfer case lever.
4 FULL TIME to 4 LO or 4 LO to 4 FULL TIME
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift
an automatic transmission to N (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 N (Neutral).
NOTE:To shift from 4 FULL TIME to 4LO, the shift
lever should be pushed away from the driver, and then
rearward into 4LO. In 4 FULL TIME, there is a neutral
stop to prevent shifting into N (Neutral) by accident.
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

PARKING BRAKE
To set the parking brake, pull the lever up as firmly as
possible. When the parking brake is applied with the
ignition ON, the “Brake Warning Light” in the instru-
ment cluster will light. To release the parking brake, pull
up slightly, press the center button, then lower the lever
completely.
NOTE:The instrument cluster “Brake Warning Light”
indicates only that the parking brake is applied. You must
be sure the parking brake is fully applied before leaving
the vehicle.
Be sure the parking brake is firmly set when parked, and the
gear shift lever is in the P (Park) position (automatic
transmission) or R (Reverse) or 1st gear (manual transmis-
sion). When parking on a hill, you should apply the parking
brake before placing the gear shift lever in P (Park), other-
wise the load on the transmission locking mechanism may
make it difficult to move the selector out of P (Park).
Parking Brake
240 STARTING AND OPERATING

WARNING!
•Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also, be certain to leave an automatic trans-
mission in P (Park), a manual transmission in R
(Reverse) or 1st gear. Failure to do so may allow the
vehicle to roll and cause damage or injury.
•Leaving children in a vehicle unattended is danger-
ous for a number of reasons. A child or others could
be injured. Children should be warned not to touch
the parking brake or the gear selector lever. Don’t
leave the keys in the ignition. A child could operate
power windows, other controls, or move the vehicle.
•Be sure the parking brake is fully disengaged before
driving, failure to do so can lead to brake problems
due to excessive heating of the rear brakes.
When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should always be applied whenever
the driver is not in the vehicle.
ANTI-LOCK BRAKE SYSTEM — IF EQUIPPED
The Anti-Lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lock-up and help avoid skidding on slippery surfaces.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.

Refer to local laws for maximum trailer towing speeds.
288 STARTING AND OPERATING

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. With a manual transmission, shift the
transmission into reverse. And with four-wheel-drive
vehicles, make sure the transfer case is not in neutral.
Always, block orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:

If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Towing Tips — Automatic Transmission
The “D” range can be selected when towing. However, if
frequent shifting occurs while in this range, the “3” range
should be selected.
NOTE:Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See Schedule “B” in
section 8 of this manual for transmission fluid change
intervals.NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — O/D OFF (If Equipped)
To reduce potential for automatic transmission overheat-
ing, press the “O/D OFF” button when driving in hilly
areas or shift the transmission to Drive position 2 on
more severe grades. Refer to “Transmission Shifting” in
this section.
Towing Tips — Electronic Speed Control (If
Equipped)

Don’t use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.

CAUTION!
Transmission damage may occur if the automatic
transmission is shifted into P (Park) with the transfer
case in N (Neutral) and the engine running. With the
transfer case in N (Neutral) ensure that the engine is
OFF prior to shifting the transmission into P (Park)
(refer to steps7–8above).
Shifting Out Of Neutral (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Shift transmission into N (Neutral).
2. Turn engine off.
3. Shift transfer case lever to desired position.
4. Shift automatic transmission into P (Park).5. Start engine.
6. Shift automatic transmission into D (Drive) or manual
transmission into any forward gear.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (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.
298 STARTING AND OPERATING

WARNING!
Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or clothing.
Don’t lean over battery when attaching clamps or
allow the clamps to touch each other. If acid splashes
in eyes or on skin, flush contaminated area immedi-
ately with large quantities of water.
A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away
from the vent holes.
Do not use a booster battery or any other booster
source that has a greater than 12 volt system, i.e. Do
not use a 24 volt power source.
1. Remove all metal jewelry such as watch bands or
bracelets which might make an unintended electrical
contact.2. Park the booster vehicle within cable reach but with-
out letting the vehicles touch. Set the parking brake on
both vehicles, place the automatic transmission in P
(Park) or the manual transmission in N (Neutral), and
turn the ignition OFF.
3. Turn off the heater, radio, and all unnecessary electri-
cal loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
