(Park) position, pull it toward you, push it
completely counterclockwise against the stop,
and then push it toward the instrument panel.

Four-Wheel Drive (4WD)
System (If equipped)
*
[GF15500(F )01/96]
When you select the 4WD mode, your light
truck uses all four wheels to power itself. This
increases traction, enabling you to drive your
4x4 over terrain and road conditions two-wheel
drive vehicles cannot.
*
[GF15600(F )01/96]
Power is supplied to all four wheels through a
transfer case that allows you to select four-wheel
drive when necessary. Methods for engaging and
disengaging 4WD and low range will depend on
which system your vehicle has.

4x4 Systems Ð Lever Operated
*
[GF15800(F )01/96]
The lever operated transfer case can be placed
into four positions. The 2H position is the
two-wheel drive position in which power is
delivered only to the rear axle. The 4H position
provides four-wheel drive with power delivered
to the front and rear axles for increased traction.
The 4L position provides four-wheel drive with
power delivered to the front and rear axles
when the above average power is required at
reduced speeds. In the N (neutral) position, there
is no power delivered to either axle.
[GF15850(F )05/96]
When the transfer case is in the N (Neutral)
position, the engine and transmission are

All utility-type and Four-Wheel Drive vehicles
have special design and equipment features to
make them capable of performing in a wide
variety of off-road applications. Specific design
characteristics give them higher centers of
gravity than ordinary passenger cars.
*
[GF20650(F )01/96]
RWARNING
Utility and four-wheel drive vehicles are
NOT designed for cornering at speeds as
high as passenger cars any more than
low-slung sports cars are designed to
perform satisfactorily under off-road
conditions. Avoid sharp turns or abrupt
maneuvers in these vehicles.

[GF20700(F )01/96]
Driving With a Heavy Load
*
[GF20710(F )01/96]
There are limits to the amount of weight your
vehicle can carry or tow. The total weight of
your vehicle, plus the weight of the passengers
and cargo, should never be more than the Gross
Vehicle Weight Rating (GVWR). Also, the weight
that your vehicle carries over the front axle and
rear axle should never be more than the Gross
Axle Weight Rating (GAWR) for the respective
axle.
*
[GF20715(F )01/96]
The weight limits of your vehicle's tires affect
the GVWR or GAWR limitations. Usage of
replacement tires with higher weight limits than
originals does not increase GVWR or GAWR.
Usage of lower capacity replacement tires may
lower GVWR and GAWR limitations.
*
[GF20720(F )01/96]
RWARNING
Do not exceed the GVWR or the GAWR
specified on the Safety Compliance
Certification Label.

RWARNING
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 safety belts. Be sure
everyone in your vehicle is in a seat and
using a safety belt properly.
*
[GF20840(FM)05/96]
RWARNING
Cargo should always be secured to
prevent it from shifting and causing
damage to the vehicle or harm to
passengers.
*
[GF20842(FM)01/96]
Trucks, unlike passenger cars, are basically
custom vehicles designed to carry a load. Most
owners start with a base vehicle and add
production and dealer installed and/or
aftermarket components to suit their tastes and
purposes. Even trucks that are purchased for
personal transportation only are likely to have
considerable optional equipment, such as step
bumpers and light bars, for example.
*
[GF20845(FM)01/96]
Each additional item of equipment affects how
much cargo a vehicle can carry. If a vehicle is
overloaded, performance will suffer and service
concerns may arise.

Trailer Brakes
*
[GF22100(FM)01/96]

system directly to your vehicle's brake
system. Your vehicle may not have
enough braking power and your chances
of having a collision greatly increase.
