DRIVING AND OPERATING 235
Remember: Antilock brakes help avoid
only the braking skid.
Off-Road Driving
Four-wheel-drive vehicles can be used
for off-road driving. Vehicles without
four-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. For contact information about
the original equipment tires, see the
warranty manual.
One of the best ways for successful
off-road driving 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
four-wheel-drive vehicles in this
manual.
.Know the local laws that apply to
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.
.Keep cargo in the cargo area as
far forward and as low as
possible. The heaviest things
should be on the floor, forward
of the rear axle.
.Heavy loads on the roof raise the
vehicle's center of gravity,
making it more likely to roll over.
You can be seriously or fatally(Continued)
Warning (Continued)
injured if the vehicle rolls over.
Put heavy loads inside the cargo
area, not on the roof.
For more information about loading
the vehicle, see Vehicle Load Limits
0 241 and
Tires 0402.
Environmental Concerns
.Always use established trails, roads,
and areas that have been set aside
for public off-road recreational
driving and obey all posted
regulations.
.Do not damage shrubs, flowers,
trees, or grasses or disturb wildlife.
.Do not park over things that burn.
See Parking over Things That Burn
0 251.
Driving on Hills
Driving safely on hills requires good
judgment and an understanding of
what the vehicle can and cannot do.

DRIVING AND OPERATING 245
{Warning
Things you put 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. 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.
.Do not leave an unsecured
child restraint in the vehicle.
.When you carry something
inside the vehicle, secure it
whenever you can.
.Do not leave a seat folded
down unless you need to. There is also important loading
information for off-road driving in
this manual. See
“Loading the
Vehicle for Off-Road Driving”
under Off-Road Driving 0235.
Add-On Equipment
There may be a limit on how
many people can be inside the
vehicle when carrying removable
items. Be sure to weigh the vehicle
before buying and installing the
new equipment.
Caution
Overloading the vehicle may cause
damage. Repairs would not be
covered by the vehicle warranty. Do
not overload the vehicle.
Remember not to exceed the
Gross Axle Weight Rating (GAWR)
of the front or rear axle.
Starting and Operating
New Vehicle Break-In
Caution
The vehicle does not need an
elaborate break-in. But it will
perform better in the long run if
you follow these guidelines:
.Do not drive at any one constant
speed, fast or slow, for the first
800 km (500 mi). Do not make
full-throttle starts. Avoid
downshifting to brake or slow the
vehicle.
.Avoid making hard stops for the
first 300 km (200 mi) or so.
During this time the new brake
linings are not yet broken in.
Hard stops with new linings can
mean premature wear and earlier
replacement. Follow this
breaking-in guideline every time
you get new brake linings. (Continued)

trailer brake controller to check the
trailer brakes work. During the trip,
occasionally check that the cargo and
trailer are secure and that the lamps
and any trailer brakes are working.
Towing with a Stability Control
System
When towing, the stability control
system might be heard. The system
reacts to vehicle movement caused by
the trailer, which mainly occurs
during cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving without a trailer. This can help
to avoid heavy braking and sudden
turns.
Passing
More passing distance is needed when
towing a trailer. The combination of
the vehicle and trailer will not
accelerate as quickly and is much
longer than the vehicle alone. It is
necessary to go much farther beyondthe passed vehicle before returning to
the lane. Pass on level roadways.
Avoid passing on hills if possible.
Backing Up
Hold the bottom of the steering wheel
with one hand. To move the trailer to
the left, move that hand to the left. To
move the trailer to the right, move
that hand to the right. Always back up
slowly and, if possible, have someone
guide you.
Making Turns
Caution
Turn more slowly and make wider
arcs when towing a trailer to
prevent damage to your vehicle.
Making very sharp turns could
cause the trailer to contact the
vehicle.
Make wider turns than normal when
towing, so trailer will not go over soft
shoulders, over curbs, or strike road
signs, trees, or other objects. Always
signal turns well in advance. Do not
steer or brake suddenly.
Driving on Grades
Reduce speed and shift to a lower gear
before starting down a long or steep
downhill grade. If the transmission is
not shifted down, the brakes may
overheat and result in reduced braking
efficiency.
The vehicle can tow in D (Drive). Shift
the transmission to a lower gear if the
transmission shifts too often under
heavy loads and/or hilly conditions.
When towing at higher altitudes,
engine coolant will boil at a lower
temperature than at lower altitudes.
If the engine is turned off immediately
after towing at high altitude on steep
uphill grades, the vehicle could show
signs similar to engine overheating. To
avoid this, let the engine run,
preferably on level ground, with the
transmission in P (Park) for a few
minutes before turning the engine off.
If the overheat warning comes on, see
Engine Overheating 0381.

344 DRIVING AND OPERATING
If a cargo carrier is used in the trailer
hitch receiver, choose a carrier that
positions the load as close to the
vehicle as possible. Make sure the
total weight, including the carrier, is
no more than half of the maximum
allowable tongue weight for the
vehicle or 227 kg (500 lb), whichever
is less.
Rear Gross Axle Weight Rating
(GAWR-RR)
The GAWR-RR is the total weight that
can be supported by the rear axle of
the vehicle. Do not exceed the
GAWR-RR for the vehicle, with the
tow vehicle and trailer fully loaded for
the trip including the weight of the
trailer tongue. If using a
weight-distributing hitch, do not
exceed the GAWR-RR after applying
the weight distribution spring bars.The GAWR-RR for the vehicle is on
the Trailering Information Label.
Ask your dealer for trailering
information or assistance.
Towing Equipment
Hitches
{Warning
In order to avoid serious injury or
property damage, always follow the
hitch manufacturer's instructions
when securing your draw bar/
coupling device to the vehicle's
hitch receiver.
Ensure that the draw bar/coupling
device is secured with a locking
retainer pin or other means such
that rotation of the pin or locking
mechanism will not cause the pin
to back out or loosen during use.
Failure to correctly secure the draw
bar/coupling device to the receiver
can result in separation of the
hitch/receiver while towing.
