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
Page 272 of 450

The ABS 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 (ABS) — If
Equipped
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer 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 ABS includes an amber “ABS Warning Light.” When
the light is illuminated, the ABS is not functioning. The
system reverts to standard non-anti-lock brakes. Turning
the ignition OFF and ON again may reset the ABS if the
fault detected was only momentary.

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. Do not 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. 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.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without
stopping when you are stuck.
Refer to “Freeing A Stuck Vehicle” in “What To Do In
Emergencies” for further information.
286 STARTING AND OPERATING

•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE:It is particularly important for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
•Receiver module
•Four tire pressure monitoring sensors
•Tire Pressure Monitoring Telltale Light The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more of
the four active road tire pressures are low. Should this
occur, you should stop as soon as possible, check the
inflation pressure of each tire on your vehicle, and inflate
each tire to the vehicle’s recommended cold placard
pressure value. The system will automatically update
and the “Tire Pressure Monitoring Telltale Light” will
extinguish once the updated tire pressures have been
received. The vehicle may need to be driven for up to
20 minutes above 15 mph (25 km/h) to receive this
information.
The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. The “Tire
Pressure Monitoring Telltale Light” will turn off when
296 STARTING AND OPERATING

the fault condition no longer exists. A system fault can
occur by any of the following scenarios: 1) Jamming due
to electronic devices or driving next to facilities emitting
the same radio frequencies as the TPM sensors; 2) Install-
ing some form of aftermarket window tinting that affects
radio wave signals; 3) Lots of snow or ice around the
wheels or wheel housings; 4) Using tire chains on the
vehicle; 5) Using wheels/tires not equipped with TPM
sensors.
NOTE: Your vehicle is equipped with a non-matching
full size spare wheel and tire assembly.
1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.
2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warninglimit, upon the next ignition key cycle a chime will sound
and the “TPM Telltale Light” will still turn ON due to the
low tire.
3. However, after driving the vehicle for up to 20 min-
utes above 15 mph (25 km/h), the “TPM Telltale Light”
will flash on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition key cycle, a chime will
sound and the “TPM Telltale Light” will flash on and off
for 75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the full size spare tire,
the TPMS will update automatically and the “TPM
Telltale Light” will turn OFF, as long as no tire pressure is
below the low-pressure warning limit in any of the four
active road tires. The vehicle may need to be driven for
up to 20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.

WARNING! (Continued)
•When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis 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 PARK. For four-wheel drive ve-
hicles, make sure the transfer case is not in NEU-
TRAL. Always, block or\bchock\bthe trailer wheels.
(Continued)
WARNING! (Continued)
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer so that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch uti-
lized (This requirement may limit the ability to
always achieve the 10% to 15% range of tongue
weight as a percentage of total trailer weight.)

WARNING!
Do not add a snow plow, winches, or any other
aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Two-Wheel Drive Models
Recreational towing of two-wheel drive models is not
allowable. Towing the vehicle with the transmission in
NEUTRAL can cause severe transmission damage. Re-
moval of the driveshaft for towing is not recommended,
since this would allow fluid to drain from the
transmission.
Four-Wheel Drive Models
CAUTION!
•Internal damage to the transfer case will occur if a
front or rear wheel lift is used when recreational
towing.
•The transfer case must be shifted into NEUTRAL
for recreational towing. The NEUTRAL button is
located on the lower left hand corner of the trans-
fer case switch. Shifts into and out of transfer case
NEUTRAL can take place with the transfer case
switch in any mode position.
•Automatic transmissions must be placed in PARK
position for recreational towing.
•Failure to follow these procedures can cause se-
vere transmission and/or transfer case damage.
