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. 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.
FOUR-WHEEL DRIVE OPERATION
NV 233 Transfer Case Operating
Information/Precautions
The NV233 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 NV233 transfer case provides 4 mode positions: 2
(rear) wheel drive high range, 4 wheel drive high range,
4 wheel drive low range, and neutral.
The NV233 transfer case is designed to be driven in the 2
wheel drive position (2WD) for normal street and high-
way conditions (dry hard surfaced roads).
When additional traction is required, the transfer case
4HI and 4LO 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 rotating the 4WD Control Switch to the desired
206 STARTING AND OPERATING

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:
2WD
Rear Wheel Drive High Range - Normal street and
highway driving. Dry hard surfaced roads.4HI
4 Wheel Drive High Range - Locks the front and rear
driveshafts together. Forces the front and rear wheels to
rotate at the same speed. Additional traction for loose,
slippery road surfaces only.
4LO
4 Wheel Drive Low Range - Low speed 4 wheel drive.

Shifting Procedure - NV233 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 indicator
light will continue to flash until all the requirements for
the selected position have been met. To retry a shift:return the control knob back to the original position,
make certain all shift requirements have been met, wait
five (5) seconds and try the shift again.
2WD to 4HI or 4HI to 2WD
Rotate the 4WD Control Switch to the desired position.
Shifts between 2WD and 4HI 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 turning
the control 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 accessory position.
NOTE:On vehicles equipped with Anti-Lock Brake
Systems, the 4x4 system will not allow shifts between
2WD/ 4HI if the rear wheels are spinning (no traction). In
this situation the selected position indicator light will
flash and the original position indicator light will remain
210 STARTING AND OPERATING
Page 213 of 392

When additional traction is required, the 4HI and 4LO
positions can be used to lock the front and rear drive-
shafts together through the transfer case inter-axle differ-
ential and force the front and rear wheels to rotate at the
same speed. This is accomplished by rotating the 4WD
Control Switch to these positions. The 4HI and 4LO
positions are intended for loose, slippery road surfaces
only. Driving in the 4HI and 4LO positions on dry hard
surfaced roads may cause increased tire wear and dam-
age to the driveline components.
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.
NOTE:The transfer case Neutral (N) position is to be
used for recreational towing only. (See Recreational Tow-
ing section for specific procedures on shifting into and
out of Neutral (N).Transfer Case Position Indicator Lights
Transfer case position indicator lights are located on the
instrument cluster. If there are no indicator lights on or
flashing the transfer case position is all-wheel drive
(AWD). If an indicator light is on, the desired position
(4HI or 4LO) has been met.
If One or More Shift Requirements are not Met
1. An indicator light will flash until conditions are met.
2. The transfer casewill 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 control knob back to the current position, wait five (5)
seconds, and retry selection. To find the shift require-
ments, refer to theShifting Procedurefor your transfer
case, located in this section of the owner’s manual.

Shifting Procedure - NV244 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 indicator
light will continue to flash until all the requirements for
the selected position have been met. To retry a shift:return the control knob back to the original position,
make certain all shift requirements have been met, wait
five (5) seconds and try the shift again.
AWD to 4HI or 4HI to AWD
Rotate the 4WD Control Switch to the desired position.
Shifts between AWD and 4HI 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 turning
the control 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 accessory position.
NOTE:On vehicles equipped with a Anti-Lock Brake
Systems, the 4x4 system will not allow shifts between
AWD/ 4HI if the rear wheels are spinning (no traction).
In this situation an indicator light will flash until condi-
tions are met. At this time, reduce speed and stop
216 STARTING AND OPERATING

Care should be taken to avoid sudden accelerations when
both rear wheels are on a slippery surface. This could
cause both rear wheels to spin, and allow the vehicle to
slide sideways on the crowned surface of a road or in a
turn.
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.
Be sure the parking brake is firmly set when parked and
the gear-shift lever is in PARK position. When parking on
a hill you should apply the Parking Brake before placing
the gear shift lever in PARK; otherwise the load on the
transmission locking mechanism may make it difficult to
move the selector out of PARK.

BRAKE SYSTEM
In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
off), the brakes will still function. The effort required to
brake the vehicle will be significantly increased over that
required with the power system operating.
If either the front or rear hydraulic system loses normal
capability, the remaining system will still function with
some loss of braking effectiveness. This will be evident by
increased pedal travel during application, greater pedal
force required to slow or stop, and activation of the Brake
Warning light and the ABS light during brake use.
Rear Wheel Anti-Lock Brake System — (If
Equipped)
This Anti-Lock Brake System provides increased vehicle
stability and brake performance under most braking
conditions. The system automatically controls the opera-
tion of the rear brakes to prevent rear wheel lockup.The system remains operational in the four-wheel drive
mode. The level of performance is reduced when the
front brakes are locked up. This will cause the rear brakes
to lock-up through the drivetrain, which may reduce the
effectiveness of the anti-lock system.
During severe braking conditions, particularly with
changing road surfaces, such as ice to concrete, a slight
drop or minor pulsation may be felt in the brake pedal.
WARNING!
Both Anti-Lock Brake Systems contain sophisticated
electronic equipment. It may be susceptible to inter-
ference caused by improperly installed or high out-
put radio transmitting equipment. This interference
can cause possible loss of anti-lock braking capabil-
ity. Installation of such equipment should be done
by qualified professionals.
