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 four mode posi-
tions: 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
4WD LOCK and 4WD LOW positions can be used to lockthe 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 - Refer to ªShifting Procedureº in this
section. The 4WD LOCK and 4WD LOW positions are
designed for loose or slippery road surfaces only. Driving
in the 4WD LOCK and 4WD LOW positions on dry
hard-surfaced roads may cause increased tire wear and
damage to the driveline components.
The transfer case NEUTRAL 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 position is to be
used for recreational towing only. Refer to ªRecreational
Towingº in Section 5 for specific procedures on shifting
into and out of NEUTRAL.

NOTE: Before raising the wheel off the ground, make
sure that the jack will not damage surrounding truck
parts and adjust the jack position as required.
5. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
6. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel. Lightly tighten the nuts. To
avoid risk of forcing the vehicle off the jack, do not fully
tighten the nuts until the vehicle has been lowered.
7. Using the wheel wrench, finish tightening the nuts in
a crisscross pattern. Correct nut tightness is 120 to 160 ft
lbs (163 to 217 N´m). If in doubt about the correct
tightness, have them checked with a torque wrench by
your authorized dealer or at a service station.
