Luggage Carrier
If your vehicle has this feature, you can load cargo
on your vehicle.
The luggage carrier consists of siderails attached
to the roof. The crossrails attach into the
siderails and can be moved back and forth to
accommodate various cargo sizes.
Notice:Loading cargo on the luggage carrier
that weighs more than 250 lbs. (113 kg) or
hangs over the rear or sides of the vehicle may
damage your vehicle. Load cargo only on
top of the crossrails and tie the cargo down to
the crossrail support cargo tie-down loops,
making sure to fasten it securely
Do not exceed the maximum vehicle capacity
when loading your vehicle. For more information
on vehicle capacity and loading, seeLoading Your
Vehicle on page 289.
Adjusting the Crossrails
Adjust the crossrails to t your load by doing the
following:
1. Use the provided crossrail key to unlock the
crossrail end cap by turning it
counterclockwise.
144

Stop Tabs
If your vehicle has a sunroof, it will have a
crossrail stop tab placed in the siderail. This tab
prevents you from moving the crossrails past
the opening of the sunroof and loading cargo too
far forward.
Your vehicle may have cargo tie downs. Once you
load the cargo onto the crossrails, secure it by
tying it down to the cargo tie downs. Do not load
cargo directly on the roof of your vehicle. See
Cargo Tie Downs on page 146for more
information.
Rear Storage Area
Your vehicle has a rear storage area located on
the passenger’s side of the cargo area. To
open, pull the two tabs out and open lid.
Convenience Net
Your vehicle may have a convenience net in the
rear of the vehicle. Put small loads behind the net.
The net is not for heavier loads. Store them as
far forward as you can.
Cargo Cover
Notice:If you put items onto the cargo cover,
the weight of the items could cause the
attachment clips to break. You would no longer
be able to attach and use the cargo cover.
The repairs would not be covered by your
warranty. Never put anything on top of
the cargo cover.
If your vehicle has a cargo cover, you can use it
to cover items in the rear of the vehicle. Remove
the cover from its pouch and place the loops
found on each corner of the cover, over the
two pegs in each corner of the rear if the vehicle.
When it is not in use, fold up the cover and
return it to the pouch.
Cargo Tie Downs
Your vehicle may have four cargo tie-downs.
These tie-downs are located in tracks on the roof
of the vehicle. Each tie-down can be moved to
anywhere on the track. To loosen, turn the
tie-down counterclockwise until it moves freely in
the track. To tighten, turn the tie-down clockwise.

{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint,
no system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger
sensing system has turned off the right front
passenger’s frontal airbag. SeePassenger Sensing
System on page 75for more on this, including
important safety information.If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag readiness
light ever come on together, it means that
something may be wrong with the airbag
system. If this ever happens, have the
vehicle serviced promptly, because an
adult-size person sitting in the right
front passenger seat may not have the
protection of the frontal airbag. See
Airbag Readiness Light on page 178.

While driving on a surface with reduced traction,
try your best to avoid sudden steering, acceleration,
or braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to
make a mirrored surface — and slow down when
you have any doubt.
Remember: Any Anti-Lock Brake System (ABS)
helps avoid only the braking skid.
Off-Road Driving
This off-road guide is meant to provide advice
for when you drive your vehicle off paved roads.
Also, seeBraking on page 238.
Off-road driving can be great fun. But it does have
some denite hazards. The greatest of these is
the terrain itself.
“Off-roading” means you have left the great
North American road system behind. Traffic
lanes are not marked. Curves are not banked.There are no road signs. Surfaces can be slippery,
rough, uphill or downhill. In short, you have
gone right back to nature.
Off-road driving involves some new skills. And
that is why it is very important that you read
this guide. You will nd many driving tips and
suggestions. These will help make your off-road
driving safer and more enjoyable.
Before You Go Off-Roading
There are some things to do before you go out.
For example, be sure to have all necessary
maintenance and service work done. Check to
make sure all underbody shields are properly
attached. Make sure any equipment you
may need — rst aid kit, cell phone, ashlight,
etc. — is securely stored in the vehicle.
Be sure you read all the information about your
four-wheel-drive vehicle in this manual. Is
there enough fuel? Is the spare tire fully inated?
Are the uid levels up where they should be?
What are the local laws that apply to off-roading
where you will be driving? If you do not know, you
should check with law enforcement people in
the area. Will you be on someone’s private land?
If so, be sure to get the necessary permission.

Loading Your Vehicle for Off-Road
Driving
{CAUTION:
Cargo on the load oor piled higher
than the seatbacks can be thrown
forward during a sudden stop. You
or your passengers could be injured.
Keep cargo below the top of the
seatbacks.
Unsecured cargo on the load oor can
be tossed about when driving over
rough terrain. You or your passengers
can be struck by ying objects.
Secure the cargo properly.
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 injured if the
vehicle rolls over. Put heavy loads
inside the cargo area, not on the roof.
Keep cargo in the cargo area as far
forward and low as possible.There are some important things to remember
about how to load your vehicle.
The heaviest things should be on the
load oor and forward of your rear axle.
Put heavier items in the rear area, as far
forward as you can.
Be sure the load is secured properly, so
driving on the off-road terrain does not
toss things around.
You will nd other important information in this
manual. SeeLoading Your Vehicle on page 289
andTires on page 367.
