2. Slide the crossrails to the desired position, being sure
to align the lines in the side rails with the arrows on
the crossrail supports.
3. Tighten the lock knobs and then try to move
the crossrails back and forth to be sure that they
do not move.
4. Once you load the cargo onto the crossrails, secure it
by tying it down to the crossrail support cargo
tie
-down loops. Do not load cargo directly on the
roof or your vehicle.
Be sure you do not cover the roof marker lamps or
the Center
-High-Mounted Stoplamp (CHMSL),
located above the rear glass, with cargo.
To prevent damage or loss of cargo as you’re driving,
check often to make sure that the cargo is still securely
fastened and that the crossrails are tight.
Stop Tabs
If your vehicle has a sunroof, it will have crossrail stop
tabs placed in the siderails. These tabs prevent you from
moving the crossrails past the opening of the sunroof
and loading cargo too far forward. Cargo loaded too
far forward could fall onto the sunroof and into the
passenger compartment. Loading cargo too far forward
could also cause the OnStar and navigation system
(if equipped) to function improperly or not at all.
Vehicles with the off
-road lamps will have additional
stop tabs placed in the siderails to prevent you from
moving the lamps too far rearward, causing them to
shine into the optional sunroof opening.
