reducing vehicle speed by
shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes
help avoid only the
braking skid.
Off-Road Driving
All-Wheel Drive vehicles can
be used for off-road driving.
Vehicles without All-Wheel
Drive and vehicles not
equipped with All Terrain (AT)
or On-Off Road (OOR) tires
must not be driven off-road
except on a level, solid
surface. To contact the tire
manufacturer for more
information about the original
equipment tires, see the
Limited Warranty and Owner
Assistance Information
manual.
Controlling the vehicle is the
key to successful off-road
driving. One of the best ways
to control the vehicle is to
control the speed.
{Warning
When driving off-road,
bouncing and quick changes
in direction can easily throw
you out of position. This
could cause you to lose
control and crash. You and
your passengers should
always wear seat belts.
Before Driving Off-Road
.Have all necessary
maintenance and service
work completed.
.Fuel the vehicle, fill fluid
levels, and check inflation
pressure in all tires, including
the spare, if equipped.
.Read all the information
about All-Wheel Drive
vehicles in this manual.
.Make sure all underbody
shields, if equipped, are
properly attached.
.Know the local laws that
apply to off-road driving. To gain more ground
clearance if needed, it may be
necessary to remove the front
fascia lower air dam. However,
driving without the air dam
reduces fuel economy.
Caution
Operating the vehicle for
extended periods without
the front fascia lower air
dam installed can cause
improper airflow to the
engine. Reattach the front
fascia air dam after off-road
driving.
Loading the Vehicle for
Off-Road Driving
{Warning
.Unsecured cargo on the
load floor can be tossed
about when driving over
rough terrain. You or your
passengers can be struck
by flying objects. Secure
the cargo properly.

The Tire and Loading
Information label also
shows the size of the
original equipment tires (3)
and the recommended cold
tire inflation pressures (4).
For more information
on tires and inflation see
Tires0400 and
Tire Pressure 0408.
There is also important
loading information on the
vehicle Certification/Tire
label. It may show the
Gross Vehicle Weight
Rating (GVWR) and the
Gross Axle Weight Rating
(GAWR) for the front and
rear axle. See
“Certification/Tire Label”
later in this section.
“Steps for Determining
Correct Load Limit– 1.
Locate the statement
"The combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs." on
your vehicle’s placard.
2.Determine the combined
weight of the driver and
passengers that will be
riding in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from
XXX kg or XXX lbs.
4.The resulting figure
equals the available
amount of cargo and
luggage load capacity.
For example, if the
"XXX" amount equals
1400 lbs. and there will
be five 150 lb
passengers in your
vehicle, the amount of
available cargo and
luggage load capacity is
650 lbs. (1400-750 (5 x
150) = 650 lbs.)
5.Determine the combined
weight of luggage and
cargo being loaded on
the vehicle. That weight
may not safely exceed
the available cargo and
luggage load capacity
calculated in Step 4.
6.If your vehicle will be
towing a trailer, load
from your trailer will be
transferred to your
vehicle. Consult this
manual to determine
how this reduces the
available cargo and
luggage load capacity of
your vehicle.”
See Trailer Towing 0351
for important information
on towing a trailer, towing
safety rules and
trailering tips.

and seating positions. The
combined weight of the
driver, passengers, and
cargo should never exceed
the vehicle's capacity
weight.
Certification/Tire Label
Label Example
A vehicle-specific
Certification/Tire label is
attached to the center
pillar (B-pillar).
The label may show the
size of the vehicle's original
tires and the inflationpressures needed to obtain
the gross weight capacity
of the vehicle. The label
shows the gross weight
capacity of the vehicle. This
is called the Gross Vehicle
Weight Rating (GVWR). The
GVWR includes the weight
of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label
may also show the
maximum weights for the
front and rear axles, called
the Gross Axle Weight
Rating (GAWR). To find out
the actual loads on the
front and rear axles, weigh
the vehicle at a weigh
station. Your dealer can
help with this. Be sure to
spread the load equally on
both sides of the
centerline.
Caution
Overloading the vehicle may
cause damage. Repairs
would not be covered by the
vehicle warranty. Do not
overload the vehicle.
{Warning
Things inside the vehicle
can strike and injure
people in a sudden stop
or turn, or in a crash.
.Put things in the cargo
area of the vehicle. In
the cargo area, put
them as far forward as
possible. Try to spread
the weight evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so
that some of them are
above the tops of the
seats.

additional information refer
to the tire manufacturer.
{Warning
.Poorly maintained and
improperly used tires
are dangerous.
.Overloading the tires
can cause overheating
as a result of too much
flexing. There could be
a blowout and a serious
crash. See Vehicle Load
Limits0252.
.Underinflated tires
pose the same danger
as overloaded tires. The
resulting crash could
cause serious injury.
Check all tires
frequently to maintain

should be checked
when the tires are cold.
.Overinflated tires are
more likely to be cut,
punctured, or broken by
a sudden impact —such
as when hitting a
pothole. Keep tires at
the recommended
pressure.
.Worn or old tires can
cause a crash. If the
tread is badly worn,
replace them.
.Replace any tires that
have been damaged by
impacts with potholes,
curbs, etc.
.Improperly repaired
tires can cause a crash.

center should repair,
replace, dismount, and
mount the tires.
.Do not spin the tires in
excess of 56 km/h
(35 mph) on slippery
surfaces such as snow,
mud, ice, etc. Excessive
spinning may cause the
tires to explode.
