NV244 Transfer Case Operating Information /
Precautions
The NV244 is an electric shift transfer case and is
operated by the 4WD Control Switch, which is located on
the instrument panel.
The NV244 transfer case provides 4 mode positions -
Normal all wheel drive high range, 4 wheel drive high
range, 4 wheel drive low range, and neutral.
This transfer case is equipped with an inter-axle differ-
ential that allows driving the vehicle in the normal all
wheel drive position (AWD) at all times on any given
road surface, including dry hard surfaced roads. The
AWD mode allows the front and rear wheels to rotate at
different speeds. This eliminates driveline binding and
component wear normally associated with driving the
vehicle in the 4HI position on dry hard surfaced roads.
This feature provides the safety, security, and conve-
nience of operating in all wheel drive at all times
regardless of road conditions.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
Four-Wheel-Drive Control Switch, found on your instru-
ment panel, and indicate the current and desired transfer

from the powertrain. To be used for flat towing behind
another vehicle. See Recreational Towing for more infor-
mation.
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.
160 STARTING AND OPERATING

adhere to the loading conditions, tire size and cold tire
inflation pressures specified on the Tire and Loading
Information placard and the Vehicle Loading section of
this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWR's) for the front and rear
axles must not be exceeded. For further information on
GAWR's, vehicle loading and trailer towing, see the
Vehicle Loading section of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement ªThe combined weight of
occupants and cargo should never exceed XXX kg or XXX
lbs.º on the Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps for Determining Correct Load Limit
1. Locate the statement ªThe combined weight of occu-
pants and cargo should never exceed XXX poundsº on
your vehicle's placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.3. Subtract the combined weight of the driver and pas-
sengers from XXX kilograms or XXX pounds.
4.
The resulting figure equals the available amount of cargo
and luggage load capacity. For example, if ªXXXº amount
equals 1400 lbs. and there will be five 150 lb. passengers in
your vehicle, the amount of available cargo and luggage
load capacity is 650 lb. (1400±750 (5 x 150) = 650 lb.)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely
exceed the available cargo and luggage load capacity
calculated in step 4.
6. If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. Consult this
manual to determine how this reduces the available
cargo and luggage load capacity of your vehicle.
NOTE:The following table shows examples on how to
calculate total load, cargo/luggage and towing capacities
of your vehicle with varying seating configurations and
number and size of occupants. This table is for illustra-
tion purposes only and may not be accurate for the
seating and load carry capacity of your vehicle.

CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
As with any vehicle do not park or operate this vehicle in
areas where combustible materials such as grass or leaves
can contact a hot exhaust system.
A scorching odor may appear if you continue to run a
malfunctioning engine. The odor may indicate severe
and abnormal catalyst overheating. If this occurs, the
vehicle should be stopped, the engine shut off and the
vehicle allowed to cool. Service, including a tune-up to
manufacturer's specifications should be obtained imme-
diately.To minimize the possibility of catalytic converter dam-
age:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
²Do not try to start the engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing.
²Do not idle the engine for prolonged periods during
very rough idle or malfunctioning operating condi-
tions.
²Do not allow vehicle to run out of fuel.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
190 STARTING AND OPERATING

See your dealer or a reputable installer of aftermarket
equipment for further information on the installation of
these supports.
WARNING!
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat belts.
Be sure every one in your vehicle is in a seat and
using a seat belt properly
TRAILER TOWING
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
Definitions
The following trailer towing related terminology defini-
tions will assist in understanding the subsequent sec-
tions:
GROSS COMBINATION WEIGHT RATING (GCWR)
is the total permissible weight of your vehicle and trailer
when weighed in combination. (Note that GCWR ratings
include a 68 kg (150 lb.) allowance for the presence of a
driver.) Tongue Weight (of a trailer) is the weight placed
on a vehicle's trailer hitch by the trailer.
GROSS TRAILER WEIGHT (GTW)is the weight of the
trailer plus the weight of all cargo, consumables and
equipment (permanent or temporary) loaded in or on the
trailer in its9loaded and ready for operation9condition.
TRAILER SWAY CONTROLis a telescoping link that
can be installed between the hitch receiver and the trailer
STARTING AND OPERATING 195
5

tongue that typically provides adjustable friction associ-
ated with the telescoping motion to dampen any un-
wanted trailer swaying motions while traveling.
CAUTION!
²During the first 500 miles (805 km) your new
vehicle is driven, do not tow a trailer. Doing so
may damage your vehicle.
²When first towing a trailer, limit your speed to 50
mph (80 km/h) during the first 500 miles (805 km)
of towing.
Consider the following items when computing the
weight on the rear axle:
²the tongue weight of the trailer
²the weight of any other type of cargo or equipment put
in or on your vehicle
NOTE:Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options, or dealer-installed options,
must be considered as part of the total load on your
vehicle. Refer to the Certification label located at the
driver's door for the Gross Vehicle Weight Rating.
Perform maintenance services as prescribed in the Main-
tenance Schedules section. When your vehicle is used for
trailer towing, never exceed the gross axle weight rating
(GAWR) and GVWR.
WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
²Be sure the trailer is loaded heavier in front, with 60%
to 65% of the weight located ahead of the trailer's
axles(s) sufficiently to place result in tongue weights of
between 10% and 15% of the GTW loaded trailer
weight on the tow hitch of your vehicle. (For a95th
196 STARTING AND OPERATING

Wheel9style trailer, this range of loading on the9King
Pin9should be between 15% and 25%.) Loads balanced
over the wheels or biased toward9heavier in the rear9
can cause the trailer to sway severely side to side
which will cause loss of control of vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer accidents.
²Donotinterconnect the hydraulic brake system of
your vehicle with that of the trailer. This could cause
inadequate braking and possible personal injury.
²Trailer brakes are recommended for trailers over 1,000
lbs. (454 kg) and required for trailers in excess of 2,000
lbs. (907 kg).
²Use an approved trailer harness and connector. If a
hitch is ordered, the proper wiring will be provided.
²When 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.
²Make certain that the load is secured in the trailer and
will not shift during travel. When trailering cargo that
cannot be fully secured, dynamic load shifts can occur
that may be difficult for the driver to control.
²All trailer hitches should be professionally installed on
your vehicle.
²Safety chains must always be used between your
vehicle and trailer.
²Connect trailer lighting and brakes using factory har-
nesses only. Do not cut or splice any wiring to the
brake circuits.
Trailer and Tongue Weight
Gross Trailer Weight (GTW) means the weight of the
trailer plus the weight of all cargo and equipment loaded
on the trailer when in actual underway towing condition.
The recommended way to measure GTW is to put your
fully loaded trailer on a vehicle scale. The entire weight
of the trailer must be supported by the scale.
Tongue Weight is the weight placed on the vehicle's
trailer hitch by the trailer. Always load a trailer with 60%
STARTING AND OPERATING 197
5

to 65% of the weight in the front of the trailer. This places
10% to 15% of the GTW on the tow hitch of your vehicle.
Trailer sway control and equalizing hitch are required for
tongue weights above 350 lbs. (159 kg).
Trailer TowingÐHitches:
With a Class I Hitch, your vehicle can be equipped to tow
trailers with a Gross Trailer Weight (GTW) of 2,000 lbs.
(907 kg) maximum. Vehicles equipped with a rear step
bumper are rated for a Class I Hitch.With a Class II Hitch, your vehicle can be equipped to
tow trailers with a Gross Trailer Weight (GTW) of 3,500
lbs. (1,587 kg) maximum. Tongue weight must be equal to
at least 10% of GTW, but no more that 15% of GTW.
With a Class III Hitch, your vehicle can be equipped to
tow trailers with a Gross Trailer Weight (GTW) of 5,000
lbs. (2,268 kg) maximum. Tongue weight must be equal to
at least 10% of GTW, but no more that 15% of GTW.
With a Class IV Hitch, you can tow a trailer with a Gross
Trailer Weight of up to 6,700 lbs. (3039 kg.) depending on
your vehicle equipment. The Trailer Tow Package in-
cludes the platform hitch receiver, and a 7 lead wiring
harness mounted on the hitch.
NOTE:When towing a trailer, the following require-
ments must be adhered to:
²GCWR must not be exceeded
²Total weight must be distributed between the tow
vehicle and the trailer such that the following four
(4) ratings are not exceeded:
