Luggage Carrier
The vehicle may have a luggage carrier that can
be used to load things on top of the vehicle.
The luggage carrier has siderails attached to the
roof. It may also have crossrails which can be
moved back and forth to help secure cargo. Tie the
load to the siderails or siderail supports.
Notice:Loading cargo on the luggage carrier
that weighs more than 200 lbs (91 kg) or
hangs over the rear or sides of the vehicle
may damage your vehicle. Load cargo so that
it rests on the slats as far forward as
possible and against the side rails, 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 425.
To prevent damage or loss of cargo while you are
driving, check to make sure the luggage and
cargo are still securely fastened.Be sure the cargo is properly loaded.If small heavy objects are placed on the roof,
cut a piece of 3/8 inch plywood to t inside
the crossrails and siderails to spread the load.
Tie the plywood to the siderail supports.
Tie the load to the crossrails or the siderail
supports. Use the crossrails only to keep the
load from sliding. To move a crossrail, lift the
release lever, on both sides of the rail, up to
loosen it. Slide the crossrail to the desired
position balancing the force side to side. Press
the release lever on both sides of the rail, down
to tighten it. Try to slide the crossrail back and
forth slightly to be sure it is tight.
If you need to carry long items, move the
crossrails as far apart as they will go. Tie the
load to the crossrails and the siderails or
siderail supports. Also tie the load to the
bumpers. Do not tie the load so tightly that the
crossrails or siderails are damaged.
After moving a crossrail, be sure it is securely
locked into the siderail.

This light will go off when you turn the airbag on.
SeeAirbag Off Switch on page 93for more on
this, including important safety information.
{CAUTION:
If the right front passenger’s airbag is
turned off for a person who is not in a risk
group identied by the national
government, that person will not have the
extra protection of an airbag. In a crash,
the airbag will not be able to inate and
help protect the person sitting there.
Do not turn off the passenger’s airbag
unless the person sitting there is in a risk
group identied by the national
government. SeeAirbag Off Switch on
page 93for more on this, including
important safety information.
{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front
passenger’s seat) until you have your
vehicle serviced. SeeAirbag Off Switch on
page 93andAirbag Readiness Light on
page 250for more on this, including
important safety information.
251

{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag. A
child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the right
front 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 97for more on this,
including important safety information.

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 the rear axle. Put
heavier items 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 425
andTires on page 550.
