102 INSTRUMENT PANEL AND CONTROLS

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

WARNING!
²Remove the fuel tank filler tube cap (gas cap)
slowly to prevent fuel spray from the filler neck
which may cause injury.
²The volatility of some gasolines may cause a
buildup of pressure in the fuel tank that may
increase while you drive. This pressure can result
in a spray of gasoline and/or vapors when the cap
is removed from a hot vehicle. Removing the cap
slowly allows the pressure to vent and prevents
fuel spray.
²Never allow any lit smoking materials near the
vehicles while removing the cap or filling the
tank.
²Never add fuel to the vehicle when the engine is
running.
Fuel Tank Filler Tube
NOTE:
On some models, the fuel tank filler tube has a
restricting door about 2 inches (50 mm) down from the
opening. If fuel is poured from a portable container, the
container should have a flexible nozzle long enough to
force open the restricting door.
CAUTION!
To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling.
NOTE:When the fuel nozzle ªclicksº or shuts off, the
fuel tank is full.
NOTE:Tighten the gas cap until you hear a ªclickingº
sound. This is an indication that the gas cap is properly
tightened.
The Check Engine light will come on if the gas cap is
not properly secured. Make sure that the gas cap is
tightened each time the vehicle is refueled.

Heavier axles or suspension components sometimes
specified by purchasers for increased durability do not
necessarily increase the vehicle's GVWR.
Tire Size
This is the minimum allowable tire size for your vehicle.
Replacement tires must be equal to the load capacity of
this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure (Cold)
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the front
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.
192 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%

4.GAWR ratings
NOTE:
Towing a trailer equipped with more than the
standard lighting (turn, tail, stop and backup lights) may
cause an abnormally high electrical current draw through
the headlight switch, causing the switch to fail. To
prevent a recurring switch failure install a trailer tow
wiring harness overlay kit with relay to bypass headlight
switch (available from your dealer).

Trailer Towing Requirements
All Dodge Dakota trucks are intended to tow trailers up
to 2,000 lbs. without added equipment or alterations to
standard equipment. Your vehicle may be factory
equipped for safe towing of trailers weighing over 2,000
lbs. with the Trailer Tow Package. The electrical part of
this package includes an instruction sheet, a 7/4 pin
adaptor, a wiring pigtail for an aftermarket electric trailer
brake controller, and three relays that must be installed
into the power distribution center. These items are stored
in the glove box. Also included in the Trailer Tow
Package are two fuses and a relay that are located on the
driver's side of the engine compartment on a harness
near the Power Distribution Center. This relay and the
fuses power up the trailer towing option. See your Dodge
dealer for further information.
If you regularly pull a trailer, regardless of the trailer size,
stop and turn signals on the trailer are recommended for
motoring safety. To handle the additional electrical load

210 WHAT TO DO IN EMERGENCIES

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.
NOTE:Fluids such as oil, power steering fluid, and
brake fluid are used during assembly plant operations to
ease the assembly of hoses to couplings. Therefore, oil
wetness at the hose-coupling area is not necessarily an
indication of leakage. Actual dripping of hot fluid when
systems are under pressure (during vehicle operation),
should be noted before hose is replaced based on leakage.
You are urged to use only manufacturer specified hoses
and clamps, or their equivalent in material and specifi-
cation, in any fuel system servicing. It is mandatory to
replace all clamps that have been loosened or removed
during service. Care should be taken in installing 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 thePCV 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
attempt to clean the oil PCV valve!Check ventilating
hose for indication of damage or plugging with deposits.
Replace if necessary.
