gear (Overdrive). The transmission will automatically
shift from Drive to Overdrive, if the following conditions
are present:
•the shift lever is in DRIVE;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the TOW/HAUL switch has not been activated;
•transmission has reached normal operating
temperature.
NOTE:
•If the vehicle is started in extremely cold temperatures,
the transmission may not shift into Overdrive and will automatically select the most desirable gear for opera-
tion at this temperature. Normal operation will re-
sume when the transmission fluid temperature has
risen to a suitable level. Refer to “Torque Converter
Clutch” in this section.
•If the transmission temperature gets extremely hot, the
transmission will automatically select the most desir-
able gear for operation at this temperature. If the
transmission temperature becomes hot enough, the
“Transmission Temperature Warning Light” may illu-
minate and the transmission may downshift out of
Overdrive until the transmission cools down. After
cool down, the transmission will resume normal
operation.
The transmission will downshift from Overdrive to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).

STARTING AND OPERATING 255
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the TOW/HAUL mode is desired,
the switch must be pressed each time the engine is
started.
Torque Converter Clutch
A feature designed to improve fuel economy is included
in all automatic transmissions. A clutch, within the
torque converter, engages automatically at a calibrated
speed at light throttle. It engages at higher speeds under
heavier acceleration. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops below a calibrated
speed, or during acceleration, the clutch automatically
and smoothly disengages. The feature is operational in
Overdrive and in Drive.NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm (usu-
ally after 1-3 miles [1.6 - 4.8 km] of driving). Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into Overdrive when cold. This is
normal. Pressing the TOW/HAUL switch, when the
transmission is sufficiently warm, will demonstrate
that the transmission is able to shift into, and out of
Overdrive.
•If the vehicle has not been driven in several days, the
first few seconds of operation after shifting the trans-
mission 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 con-
verter will refill within five seconds of shifting from
PARK into any other gear position.

STARTING AND OPERATING 257
positions are designed for loose or slippery road surfaces
only. Driving in the 4WD LOCK and 4WD LOW posi-
tions on dry hard-surfaced roads may cause increased
tire wear and damage to the driveline components.
NOTE:The transfer case NEUTRAL position is selected
by pressing the recessed button located on the lower
left-hand corner of the transfer case switch. The transfer
case NEUTRAL position is to be used for recreational
towing only. Refer to “Recreational Towing” in “Starting
and Operating” for further information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) are located on the instrument cluster. If there is
no indicator light on or flashing, the transfer case is in
two-wheel drive (2WD). If the indicator light is on, the
desired position (4WD LOCK and 4WD LOW) has been
obtained. If one or more shift requirements are not met:
1. An indicator light will flash.
2. The transfer case
will notshift.
NOTE: Before retrying a selection, make certain that all
the necessary requirements for selecting a new transfer
case position have been met. To retry the selection, turn
the transfer case switch back to the current position, wait
five seconds, and retry selection. To find the shift require-
ments, refer to the Shifting Procedurefor further
information.
The “SVC 4WD Warning Light” monitors the electronic
shift four-wheel drive system. If this light remains on
after engine start-up or illuminates during driving, it
means that the four-wheel drive system is not function-
ing properly and that service is required.

STARTING AND OPERATING 259
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SVC 4WD Warning Light” is
illuminated. Not engaging the parking brake may
allow the vehicle to roll, which may cause personal
injury.
NOTE: Do not attempt to make a shift while only the
front or rear wheels are spinning. The NV233/243 trans-
fer case is not equipped with a synchronizer and there-
fore the front and rear driveshaft speeds must be equal
for the shift to take place. Shifting while only the front or
rear wheels are spinning can cause damage to the trans-
fer case. When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD or
4WD LOCK positions at a given road speed. Take care
not to overspeed the engine and do not exceed 25 mph
(40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
260 STARTING AND OPERATING
Shifting Procedure – NV233/243 Transfer Case
NOTE:If any of the requirements to select a new
transfer case position have not been met, the transfer case
will not shift, the indicator light for the previous position
will remain ON, and the newly-selected position indica-
tor light will continue to flash until all the requirements
for the selected position have been met. To retry a shift:
return the transfer case switch back to the original
position, make certain all shift requirements have been
met, wait five seconds, and try the shift again.
2WD-to-4WD LOCK or 4WD LOCK-to-2WD
Turn the transfer case switch to the desired position.
Shifts between 2WD and 4WD LOCK can be done with
the vehicle stopped, or in motion. With the vehicle in
motion, the transfer case will engage/disengage faster if
you momentarily release the accelerator pedal after turn-
ing the transfer case switch. If the vehicle is stopped, the ignition key must be in the ON position with the engine
either running or OFF. This shift cannot be completed if
the key is in the ACC position.
NOTE:
On vehicles equipped with Anti-Lock Brake
Systems, the four-wheel drive system will not allow
shifts between 2WD/ 4WD LOCK if the rear wheels are
spinning (no traction). In this situation, the selected
position indicator light will flash and the original posi-
tion indicator light will remain ON. At this time, reduce
speed and stop spinning the wheels to complete the shift.
There may be a delay up to 10 seconds for the shift to
complete after the wheels have stopped spinning.
4WD LOCK-to-4WD LOW or 4WD LOW-to-4WD
LOCK
NOTE: When shifting into or out of 4WD LOW, some
gear noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.
262 STARTING AND OPERATING
Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h), or completely stopped. USE
EITHER OF THE FOLLOWING PROCEDURES:
Preferred Procedure
1. With the engine running, slow the vehicle to 2 to
3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, turn the transfer case switch to the
desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission back into gear.
Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the key ON and the engine either OFF or
running, shift the transmission into NEUTRAL.3. Turn the transfer case switch to the desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission back into gear.
NOTE:
•If Steps 1 or 2 of the Preferred or Alternate Procedure
are not satisfied prior to attempting the shift, or if they
no longer are being met while the shift attempt is in
process, then the indicator light will flash and the
current transfer case position will be maintained. To
retry the selection, turn the transfer case switch back to
the current position, wait five seconds, and retry shift.
•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, then the shift will not take place and
no position indicator lights will be on or flashing.

WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
•Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.

STARTING AND OPERATING 267
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
PARKING BRAKE
The foot-operated parking brake is positioned below the
lower left corner of the instrument panel. To release the
parking brake, pull the parking brake release handle.
NOTE:The “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 shift lever is in the PARK position. When parking on
a hill, you should apply the parking brake before placing
the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK.
