234 DRIVING AND OPERATING
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
0 240 and
Tires 0393.
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
0 250.
Driving on Hills
Driving safely on hills requires good
judgment and an understanding of
what the vehicle can and cannot do.

244 DRIVING AND OPERATING
{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 0234.
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:
.Keep the vehicle speed at
88 km/h (55 mph) or less for the
first 805 km (500 mi).
.Do not drive at any one constant
speed, fast or slow, for the first
805 km (500 mi). Do not make
full-throttle starts. Avoid
downshifting to brake or slow the
vehicle.
.Avoid making hard stops for the
first 322 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)

DRIVING AND OPERATING 331
.Reverse Automatic Braking (RAB)
If equipped, the following driver
assistance features should be turned
to alert or off when towing a trailer:
.Automatic Emergency
Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian Braking (FPB)
If equipped with Lane Change Alert
(LCA), the LCA detection zones that
extend back from the side of the
vehicle do not move further back
when a trailer is towed. Use caution
while changing lanes when towing a
trailer.
If equipped with Rear Cross Traffic
Alert (RCTA), use caution while
backing up when towing a trailer, as
the RCTA detection zones that extend
out from the back of the vehicle do
not move further back when a trailer
is towed.
{Warning
When towing a trailer, exhaust
gases may collect at the rear of the
vehicle and enter if the liftgate,
trunk/hatch, or rear-most window
is open.
When towing a trailer:
.Do not drive with the liftgate,
trunk/hatch, or rear-most
window open.
.Fully open the air outlets on or
under the instrument panel.
.Also adjust the climate control
system to a setting that brings in
only outside air. See “Climate
Control Systems” in the Index.
For more information about carbon
monoxide, see Engine Exhaust
0 250.
Towing a trailer requires experience.
The combination of the vehicle and
trailer is longer and not as responsive
as the vehicle itself. Get used to the
handling and braking of the
combination by driving on a level road
surface before driving on public roads. The trailer structure, the tires, and the
brakes must be all be rated to carry
the intended cargo. Inadequate trailer
equipment can cause the combination
to operate in an unexpected or unsafe
manner. Before driving, inspect all
trailer hitch parts and attachments,
safety chains, electrical connectors,
lamps, tires, and mirrors. See
Towing
Equipment 0338. If the trailer has
electric brakes, start the combination
moving and then manually apply the
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.

338 DRIVING AND OPERATING
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.
Conventional Hitch
A conventional hitch is bolted to the
frame or cross member of the tow
vehicle, and is generally rated Class 2,
3, or 4. Always use the correct hitch
equipment for your vehicle.
Crosswinds, large trucks going by, and
rough roads can affect the trailer and
the hitch.
Proper hitch equipment for your
vehicle helps maintain control of the
vehicle-trailer combination. Many
trailers can be towed using a
weight-carrying hitch which has a
coupler latched to the hitch ball, or a
tow eye latched to a pintle hook.
Other trailers may require a
weight-distributing hitch that uses
spring bars to distribute the trailer
tongue weight between your vehicle
and trailer axles. See
“Maximum
Trailer Tongue Weight Rating” under
Trailer Towing 0334 for weight limits
with various hitch types.
Avoid sharp turns when using a
step-bumper hitch to prevent damage.
Make wider turns to prevent contact
between your trailer and your bumper.
