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 securing
various cargo sizes.
See your dealer/retailer for more information.
Notice: Loading cargo on the luggage carrier that
weighs more than 300 lbs. (136 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, see Loading Your Vehicle on
page 4-44.

Your vehicle has a rear seat armrest with cupholders.
To access, pull the tab on the armrest forward.
Cargo Tie Downs (SUT)
There are four oval shaped openings (A) in the cargo
bed that allow access to four tie downs. You can
use these tie downs to secure cargo.
