the outside. Do not grip the
spokes.
Drive cautiously to avoid vehicle
damage from concealed objects
such as rocks and stumps.
You should either know the terrain
or examine maps of the area
before driving. Map out your route
before driving in the area. For
more information on driving
off-road, read the ªFour Wheelingº
supplement in your owner's
portfolio.
If your vehicle gets stuck
If the vehicle is stuck, shift the
transmission in a steady motion
between forward and reverse
gears. Allow the transmission to
engage, then press lightly on the
accelerator.
Do not rock the vehicle for
more than a few minutes. The
transmission and tires may be
damaged or the engine can
overheat.
Do not spin the wheels at
over 56 km/h (35 mph).
The tires may fail and injure a
passenger or bystander.
Sand
When driving over sand, try to
keep all four wheels on the most
solid area of the trail. Do not
reduce the tire pressures but shift
to a lower gear and drive steadily
through the terrain. Apply the
Driving
111

accelerator slowly and avoid
spinning the wheels.
Mud and water
If you must drive through high
water, drive slowly. Traction or
brake capability may be limited.
When driving through water,
determine the depth; avoid water
higher than the bottom of the hubs
(if possible) and proceed slowly. If
the ignition system gets wet, the
vehicle may stall.
Once through water, always try the
brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes.
Drying can be improved by moving
your vehicle slowly while applying
light pressure on the brake pedal.
After driving through mud, clean
off residue stuck to rotating
driveshafts and tires. Excess mud
stuck on tires and rotating
driveshafts causes an imbalance
that could damage drive
components.
If the transmission and transfer
case are submerged in water, their
fluids should be checked and
changed, if necessary.
Water intrusion into the
transmission may damage the
transmission.
If the rear axle is submerged in
water, the rear axle lubricant
should be checked and changed, if
necessary. The rear axle is filled
with a synthetic lubricant and does
not normally require a lubricant
Driving
112

change for the life of the vehicle.
Rear axle lubricant quantities
should not need to be checked
unless a leak is suspected.
Driving on hilly or sloping
terrain
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.
When climbing a steep hill, start in
a lower gear rather than
downshifting to a lower gear from
a higher gear once the ascent has
started. This reduces strain on the
engine and the possibility of
stalling.
When descending a steep hill,
avoid sudden braking. Rapid
pumping of the brake pedal will
help slow the vehicle and still
maintain steering control.
When speed control is on and you
are driving uphill, your vehicle
speed may drop considerably,
especially if you are carrying a
heavy load.
If vehicle speed drops more than
16 km/h (10 mph), the speed
control will cancel automatically.
Resume speed with accelerator
pedal.
If speed control cancels after
climbing the hill, reset speed by
pressing and holding the SET
Driving
113

ACCEL button (to resume speeds
over 50 km/h (30 mph).
Automatic transmission may shift
frequently while driving up steep
grades. Eliminate frequent shifting
by shifting out of
(Overdrive)
into D (Drive).
Driving on snow and ice
A 4WD vehicle has advantages
over 2WD vehicles in snow and ice
but can skid like any other vehicle.
Avoid sudden applications of
power and quick changes of
direction on snow and ice. Apply
the accelerator slowly and steadily
when starting from a full stop.
When braking, apply the brakes as
you normally would. In order to
allow the anti-lock brake system
(ABS) to operate properly, keep
steady pressure on the brake
pedal.
Allow more stopping distance and
drive slower than usual. Consider
using one of the lower gears.
DRIVING THROUGH WATER
Do not drive quickly through
standing water, especially if the
depth is unknown. Traction or
brake capability may be limited
and if the ignition system gets wet,
your engine may stall. Water may
also enter your engine's air intake
and severely damage your engine.
If driving through deep or standing
water is unavoidable, proceed very
slowly. Never drive through water
that is higher than the bottom of
Driving
114

the hubs (truck)/wheel rims (car).
Once through the water, always try
the brakes. Wet brakes do not stop
the vehicle as effectively as dry
brakes. Drying can be improved by
moving your vehicle slowly while
applying light pressure on the
brake pedal.
VEHICLE LOADING
Before loading a vehicle, familiarize
yourself with the following terms:
²Base Curb Weight: Weight of
the vehicle including any
standard equipment, fluids,
lubricants, etc. It does not
include passengers or
aftermarket equipment.
²Payload: Combined maximum
allowable weight of cargo,
passengers and optional
equipment. The payload equals
the gross vehicle weight rating
minus base curb weight.
²GVW (Gross Vehicle Weight):
Base curb weight plus payload
weight. The GVW is not a limit
or a specification.
²GVWR (Gross Vehicle Weight
Rating): Maximum total weight
of the base vehicle, passengers,
optional equipment and cargo.
The GVWR is specific to each
vehicle and is listed on the
Safety Compliance Label on the
driver's door pillar.
²GAWR (Gross Axle Weight
Rating): Carrying capacity for
each axle system. The GAWR is
Driving
115

specific to each vehicle and is
listed on the Safety Compliance
Label on the driver's door pillar.
²GCWR (Gross Combined
Weight Rating): Maximum
combined weight of towing
vehicle (including passengers
and cargo) and the trailer. The
GCWR indicates the maximum
loaded weight that the vehicle is
allowed to tow.
²Maximum Trailer Weight
Rating: Maximum weight of a
trailer the vehicle is permitted
to tow. The maximum trailer
weight rating equals 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.
²Maximum Trailer Weight:
maximum weight of a trailer the
loaded vehicle (including
passengers and cargo) is
permitted to tow. It is
determined by subtracting the
weight of the loaded trailer
towing vehicle from the GCWR
for the towing vehicle.
²Trailer Weight Range:
Specified weight range that the
trailer must fall within that
ranges from zero to the
maximum trailer weight rating.
Remember to figure in the tongue
load of your loaded trailer when
figuring the total weight.
Driving
116

Do not exceed the GVWR
or the GAWR specified on
the Safety Compliance
Certification Label.
Do not use replacement tires with
lower weight capacities than the
originals because they may lower
the vehicle's GVWR and GAWR
limitations. Replacement tires with
a higher weight limit than the
originals do not increase the
GVWR and GAWR limitations.
Calculating the load your
vehicle can carry/tow
1. Use the Safety Compliance
Certification Label to find the axle
code number and engine type for
your vehicle.
2. Use the appropriate maximum
gross combined weight rating
(GCWR) chart to find the
maximum GCWR for your type
engine and rear axle ratio.
3. Weigh your vehicle as you
customarily operate the vehicle
without cargo. To obtain correct
weights, try taking your vehicle to
a shipping company or an
inspection station for trucks.
4. Subtract your loaded vehicle
weight from the maximum GCWR
on the following charts. This is the
maximum trailer weight your
vehicle can tow and must fall
below the maximum shown under
maximum trailer weight on the
chart.

Trailer towing with your vehicle
may require the use of a trailer
tow option package.
Trailer towing puts additional loads
on your vehicle's engine,
transmission, axle, brakes, tires,
and suspension. For your safety
and to maximize vehicle
performance, be sure to use the
proper equipment while towing.
Follow these guidelines to ensure
safe towing procedure:
²Stay within your vehicle's load
limits. If exceeded, cargo should
be removed from the trailer
and/or the vehicle until all
weights are within specified
limits.
²Thoroughly prepare your vehicle
for towing. Refer toPreparing
to towin this chapter.
²Use extra caution when driving
while trailer towing. Refer to
Driving while you towin this
chapter.
²Service your vehicle more
frequently if you tow a trailer.
Refer to the severe duty
schedule in the ªService Guideº.
²Do not tow a trailer until your
vehicle has been driven at least
800 km (500 miles).
²Refer to the instructions
included with towing accessories
for the proper installation and
adjustment specifications.

If your vehicle is equipped with
the optional heavy duty trailer tow
wiring, it is pre-wired for trailer
towing. An electrical connector is
provided under the instrument
panel for installing a
customer-supplied electric brake
controller. Another electrical
connector is provided at the hitch.
This connector provides power to
the trailer for taillamps, stop and
turn lamps, back up lamps, battery
charge, electric brakes (when a
customer provided controller is
installed) and ground. The kit
included with your vehicle
provides you with adaptors to
attach the brake controller and
convert the hitch connector for
Class I trailer usage.
