Roof Rack System (Option) CAUTION: If you try to carry something on top of your vehicle that is longer or wider than the luggage carrier -- like paneling, plywood, a mattress, and so forth -- the wind can catch it as you drive along. This can cause you to lose control. What you are carrying could be violently torn off, and this could cause you or other drivers to have a collision, and of course damage your vehicle. You may be able to carry something like this inside. But, never carry something longer or wider than the luggage carrier on top of your vehicle. If you have the luggage carrier, you can load things on top of your vehicle. If you do load things on the top of your vehicle, you must load them on the luggage carrier crossrails. The luggage carrier has four tie-down loops on the inside of each right and left side rail. These let you secure cargo placed on the crossrails, as long as they are not wider or longer than the luggage carrier. NOTICE: Damage may be caused to the roof of your vehicle if anything is placed directly on the roof. 2-67
