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 4-35.
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,

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.
Your vehicle has a Center High-Mounted Stoplamp
(CHMSL) located above the rear glass.
If items are loaded on the roof of the vehicle, care
should be taken not to block or damage the CHMSL unit.

If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger’s frontal airbag is enabled (may inate).
{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 1-85
for more on this, including important safety information.
