NV 244 Generation II Transfer Case Operating
Information / Precautions
The NV 244 Generation II is an electric shift transfer case
and is operated by the 4WD Control Switch, which is
located on the instrument panel.
The NV 244 Generation II transfer case provides 4 mode
positions - Normal four-wheel-drive (4WD) high range,
four-wheel-drive lock (4WD LOCK), four-wheel-drive
low (4WD LOW) range, and neutral (N).
This transfer case is equipped with an inter-axle differ-
ential that allows driving the vehicle in the normal
all-wheel-drive position (4WD) at all times on any given
road surface, including dry hard surfaced roads. The
4WD 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 4WD LOCK position on dry hard surfacedroads. This feature provides the safety, security, and
convenience of operating in all-wheel drive at all times
regardless of road conditions.
When additional traction is required, the 4WD LOCK
and 4WD LOW positions can be used to lock the front
and rear driveshafts together through the transfer case
inter-axle differential 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
4WD LOCK and 4WD LOW positions are intended for
loose, 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 (N) position is selected by
depressing the recessed button located on the lower left
hand corner of the 4WD Control Switch.

or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met.
Store heavier items down low and be sure that the weight
is distributed equally. Stow all loose items securely before
driving.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.WARNING!
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. This could
cause you to lose control. Also, overloading can
shorten the life of your vehicle.
A loaded vehicle is shown in the following example. Note
that neither GVWR nor GAWR capabilities are exceeded.
Overloading can cause potential safety hazards and
shorten service life.
NOTE: The weights shown in this chart are not the
weights for your vehicle. Also, the amount of load
added to both the front and rear axles can be computed
250 STARTING AND OPERATING

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 orchockthe 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

WARNING!
•Never allow any lit smoking materials near the
vehicles while removing the cap or filling the
tank.
•Never add fuel to the vehicle when the engine is
running.
•A fire may result if gasoline is pumped into a
portable container that is in a vehicle or on a truck
bed. You could be burned. Always place gas
containers on the ground while filling.
CHANGING A FLAT TIRE
Jack Location
In the Dakota, the scissor jack and tire changing tools for
Club Cab models are stowed in a compartment under the
rear passenger seat. Quad Cab model scissor jack and tire
changing tools are accessed by lifting up the rear passen-
ger seat.
The jack is secured in place by turning the jack screw
until the jack is secured into place.
A finger operated helper tool is provided to assist re-
moval and stowage of the jack. This tool must be
removed to operate the jack for changing the spare tire.
WHAT TO DO IN EMERGENCIES 273

WARNING!
Carefully follow these tire changing warnings to help
prevent personal injury or damage to your vehicle:
•Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.
•Block the wheel diagonally opposite the wheel to be
raised.
•Apply the parking brake firmly before jacking.
•Never start the engine with the vehicle on a jack.
•Do not let anyone sit in the vehicle when it is on a
jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated.
•If working on or near a roadway, be extremely
careful of motor traffic.
•To assure that spare tires, flat or inflated are securely
stowed, spares must be stowed with the value stem
facing the ground.
To Stow The Flat Or Spare
Turn the wheel so that the valve stem is down. Slide the
wheel retainer through the center of the wheel and
position it properly across the wheel opening.
For convenience in checking the spare tire inflation, stow
with the valve stem toward the rear of the vehicle.
Rotate the winch mechanism until the wheel is drawn
into place against the underside of the vehicle. Continue
to rotate until you feel the winch mechanism slip or click
3 times. It cannot be overtightened. Push against the tire
several times to be sure it is firmly in place.
To Stow the Flat or Spare: Wheel retainer does not fit
through the center of the aluminum wheel. The tire must
be stored in a safe manner in the bed of the truck.
282 WHAT TO DO IN EMERGENCIES

•Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor gas
mileage, and increased emissions.
Emission Related Components
Fuel System Hoses And Vapor/Vacuum Harnesses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, checking, tears, cuts, abrasions, and excessive
swelling suggest deterioration of the rubber. Particular
attention should be given to examining hose surfaces
nearest to high heat sources, such as the exhaust mani-
fold.
Insure nylon tubing in these areas has not melted or
collapsed.Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
You are urged to use only the manufacturer’s specified
hoses and clamps, or their equivalent in material and
specification, in any fuel system servicing. It is manda-
tory to replace all clamps that have been loosened or
removed during service. Care should be taken in install-
ing new clamps to insure they are properly torqued.
Positive Crankcase Ventilation (PCV) Valve
Proper operation of the crankcase ventilation system
requires that the PCV valve be free of sticking or plug-
ging because of deposits. Deposits can accumulate in the
PCV valve and passage with increasing mileage. Have
the PCV valve, hoses, and passages checked for proper
operation at the intervals specified. If the valve is
plugged or sticking, replace with a new valve –Do not
