that could damage drive
components.
If the transmission and transfer
case are submerged in water, their
fluids should be checked and
changed, if necessary.
All rear axle lubricants must be
replaced every 160,000 km
(100,000 miles) or if the axle has
been submerged in water.
Otherwise, check the lubrication of
the rear axle according to the
intervals in theService Guide.
Driving on hill or slope 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
Driving
105

heavy load. If vehicle speed drops
more than 15 - 25 km/h (8 - 14
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
ACCEL button or returning to
previous speed by pressing the
RESUME button (to resume
speeds over 50 km/h [30 mph]).
Automatic transmissions may shift
frequently while driving up on
steep grades. Eliminate frequent
shifting by shifting out of
D(Overdrive) into D (Drive).
Driving on snow and ice
An AWD vehicle has advantages
over two-wheel drive 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.
If the vehicle is stuck, shift the
transmission in a steady motion
Driving

between forward and reverse
gears. 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 55 km/h (35 mph).
The tires may fail and injure a
passenger or bystander.
VEHICLE LOADING
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.
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.
Driving
107

²Payload: Combined maximum
allowable weight of cargo,
passengers and optional
equipment. The payload equals
gross vehicle weight rating
(GVWR) minus base curb
weight.
²GVW (Gross Vehicle Weight):
Base curb weight plus the
payload weight (including
passengers, cargo, and optional
equipment). Remember, 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
particular vehicle and is listed
on the Safety Compliance
Certification Label on the
driver's door pillar.
²GAWR (Gross Axle Weight
Rating): Carrying capacity for
each axle system (front and
rear). This amount is specific to
each particular vehicle and is
listed on the Safety Compliance
Certification Label on the
driver's door pillar.
²GCWR (Gross Combined Weight
Rating): Maximum combined
weight of the towing vehicle
(including passengers and
cargo) and the trailer. The
GCWR indicates the maximum
loaded weight that the vehicle is
allowed to tow.
Driving
108

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 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.
If the GVWR or the GAWR
specified on the Safety
Compliance Certification Label is
exceeded, your vehicle may be
damaged or you may lose control
and injure someone.
To obtain correct weights, try
taking your vehicle to a shipping
company or an inspection station
for trucks.
Driving
109

Do not use replacement tires with
lower weight capacities than the
original 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.
TRAILER TOWING
Your vehicle may tow a Class I or
II trailer provided the maximum
trailer weight is less than or equal
to the maximum trailer weight
listed for your engine and rear axle
ratio. See theTrailer towing table
later in this chapter.
Do not exceed the maximum loads
stated on the Safety Compliance
Certification Label. Refer to
Vehicle loadingfor a definition of
the terms on the label.
Your vehicle's load capacity is
designated by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle.
Distribute the trailer load so that
only 10 to 15% of the total weight
of the trailer is on the tongue. Tie
down the load so that it does not
shift and change the weight on the
hitch.
Towing a trailer places an
additional load on your vehicle's
engine, transmission, axle, brakes,
tires and suspension. Inspect these
components carefully before and
after any towing operation.

If the GVWR or the GAWR
specified on the Safety
Compliance Certification Label is
exceeded, your vehicle may be
damaged or you may lose control
and injure someone.
Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limits of the vehicle and could
result in engine damage,
transmission/axle damage,
structural damage, loss of
control, and personal injury.
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

Preparing to tow
Use the proper equipment for
towing a trailer, and make sure it
is properly attached to your
vehicle. See your dealer or a
reliable trailer dealer if you require
assistance.
Hitches
Do not use or install hitches that
clamp onto the bumper or to the
axle. Underbody hitches are
acceptable if installed properly.
The rear bumper has an integral
hitch and only requires a ball with
a 3/4 inch shank diameter. The
