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
NV233/243 GII Transfer Case Operating
Information/Precautions
The NV233/243 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 NV233/243 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 NV233/243 transfer case is designed to be driven in
the 2 wheel drive position (2WD) 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 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
position - see Shifting Procedure section for specific
shifting instructions. The 4HI and 4LO positions are
designed for loose or 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.
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 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.
Four-Wheel Anti-Lock Brake System — If
Equipped
This 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.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The Anti-Lock Brake System includes an amber ABS
warning light. When the light is illuminated, the Anti-
Lock Brake System is not functioning. The system reverts
to standard non-anti-lock brakes. Turning the ignition
OFF and ON again may reset the Anti-Lock Brake System
if the fault detected was only momentary.

loading may be required for high speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious accident. Don’t drive a vehicle loaded to the
maximum capacity at continuous speeds above 75
mph (120 km/h).
Radial-Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four (or 6, in case
of trucks with dual rear wheels). Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.

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 or chockthe 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:
1. GVWR

Preparations
Park the vehicle on a firm level surface, avoiding ice or
slippery areas. Set the parking brake and place the gear
selector in PARK (automatic transmission). On Four
Wheel Drive vehicles, shift the transfer case to the “4L”
position.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if the right front
wheel is being changed, block
the left rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.
Instructions
1. Lower and remove the spare wheel, jack, and tools
from stowage.
2. Using the wheel wrench, loosen, but do not remove,
the wheel nuts by turning them counterclockwise one
turn while the wheel is still on the ground.
3. When changing a front wheel, place the jack under the
frame rail behind the wheel. Locate the jack as far
forward as possible on the straight part of the frame prior

CAUTION!
Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle.
TOWING A DISABLED VEHICLE
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use of safety chains is recom-
mended. Attach towing device to main structural mem-
bers of the vehicle — not to bumpers or associated
brackets. State and local laws applying to vehicles
under tow must be observed.
Four-Wheel Drive Vehicles
The manufacturer recommends towing with all wheels
OFF the ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of the vehicle raised
and the opposite end on a towing dolly.
Two-Wheel Drive Vehicles
Provided that the transmission is operable, tow with the
transmission in Neutral and the ignition key in the OFF
position along with the front wheels raised and the rear
wheels on the ground. The speed must not exceed 30
mph (50 km/h) and the distance must not exceed 15
miles (25 km).
