Operating in 2H with the hubs in the LOCK
position increases fuel consumption, noise,
vibration, and wear. For prolonged 2H operation
on dry pavement, set the manual locking hubs
to the FREE position.

[GF17750(F )01/96]
To shift between 4H and 4L:
[GF17800(F )04/96]
Stop the vehicle and place the automatic
transmission into NEUTRAL or depress the
clutch on manual transmission vehicles. Push the
transfer case shift knob down (toward the
ground) and at the same time pull or push the
lever straight forward or rearward (depending
on the desired position 4H or 4L) in order to
shift the transfer case. This shift should be with
one continuous motion without pausing in the N
(neutral) position. Pausing in the neutral position
can result in gear clash and difficult shifting. If,
while shifting between 4H and 4L, the transfer
case gets stuck in the N (neutral) position or is
difficult to shift into either 4H or 4L, it may be
necessary to let the vehicle roll slightly and/or
turn off the engine (particularly on vehicles
equipped with automatic transmission).

% [GF19350(F )04/96]Driving Off Road with 4-Wheel
Drive
[GF19400(F )04/96]
Most vehicles with four-wheel drive are
especially equipped for driving on sand, snow,
mud, or rough terrain and have operating
characteristics that are somewhat different from
conventional vehicles, both off and on the road.
The driving tips below will help you learn to
use four-wheel drive.
[GF19450(F )04/96]
q
Do not use 4WD LOW on dry, hard-surfaced
roads.
*
[GF19500(F )01/96]
q
Special maintenance procedures are necessary
after operating with drive components in
water.
*
[GF19550(F )01/96]
q
Manual locking hubs must be in LOCK
position before shifting into four-wheel drive.
[GF19600(F )04/96]
When using four-wheel drive, maintain steering
wheel control at all times, especially in rough
terrain. Since sudden changes in terrain can
result in abrupt steering wheel motion, make
sure you grip the steering wheel rim from the
outside. Do not grip the spokes.

Driving on Hill or Slope Terrain
[GF20300(F )04/96]
When driving on a hill, avoid driving crosswise
or turning on steep slopes, you could lose
traction and slip sideways. Drive straight up,
straight down or avoid the hill completely.
Know the conditions on the other side of a hill
before driving over the crest.
*
[GF20350(F )01/96]
When climbing a steep hill, start in a lower gear,
rather than finding it necessary to downshift
from a higher gear after the ascent has started.
This reduces strain on the engine and the
possibility of stalling.
*
[GF20400(F )01/96]
When descending a steep hill avoid sudden
braking. Rapid pumping of the brake pedal will
help slow the vehicle and still maintain steering
control.
*
[GF20450(F )01/96]
Driving on Snow or Ice
[GF20500(F )04/96]
A four-wheel drive vehicle has advantages over
two-wheel drive vehicles in snow and ice but
can skid like any other vehicle. If so equipped,
keep the vehicle in four-wheel drive if icy or
slippery conditions exist.
*
[GF20550(F )01/96]
Avoid sudden applications of power and quick
changes of direction on snow or ice. Apply the
accelerator slowly and steadily when starting
from a full stop.

Trailer Towing
*
[GF20772(FM)03/96]
All vehicles may tow a Class I trailer provided
the Gross Combined Weight (GCW) is less than
or equal to the GVWR shown on the Safety
Compliance Certification Label. For heavier
trailer applications, refer to the towing
information found later in this chapter.
*
[GF20775(FM)01/96]
Towing a trailer puts additional loads on your
vehicle's engine, transmission, axle, brakes, tires
and suspension. For your safety and for the
good of your vehicle, use the right equipment
for the type of trailer you tow.
[GF20780(F )01/96]
If your trailer is equipped with electric brakes,
auxiliary battery, or back-up lamps, the optional
7 wire trailer towing electrical hook-up will be
required on the vehicle.

[GF21090(FM)01/96]
Passenger car type tires when installed on light
trucks and multipurpose passenger vehicles are
rated at 10% lower load carrying capacity due to
the differences in vehicle usages.
*
[GF21100(F )01/96]
The vehicle must not be loaded to both the front
and rear GAWR because the GVWR will be
exceeded. The GAWR of the front and rear axles
exceeds the GVWR when added together to
allow flexibility in fore and aft loading of cargo.
*
[GF21110(FM)03/96]
With the tires inflated to the specified pressure,
the total weight of your vehicle must not exceed
the GVWR and GAWR specified on the Safety
Compliance Certification Label. This includes full
fuel tank(s), vehicle equipment, and occupants as
well as the cargo load.
*
[GF21120(FM)01/96]
GCWR (Gross Combined Weight Rating)
*
[GF21130(FM)01/96]
GCWR is the maximum combined weight of the
towing vehicle (including passengers and cargo)
and the loaded trailer. The GCWR is specified
by the manufacturer to indicate the combined
maximum loaded weight that the vehicle is
designed to tow.
*
[GF21140(FM)01/96]
Maximum Trailer Weight Rating
*
[GF21150(FM)01/96]
The maximum trailer weight rating is the
maximum weight of a trailer the vehicle is
permitted to tow. It is specified by the
manufacturer and is determined by subtracting
the vehicle curb weight for each
engine/transmission combination, any required
option weight for trailer towing and the weight
of the driver from the GCWR for the towing
vehicle.
