WARNING (Continued)
Never carry something longer or
wider than the roof rack on top of
the vehicle unless using a GM
Certified accessory carrier.
This vehicle may be equipped with a
roof rack. For roof racks that do not
have cross rails included, GM
Certified cross rails can be
purchased as an accessory. See
your dealer/retailer for additional
information.
Notice: Loading cargo on the
roof rack that weighs more than
100 kg (220 lbs) or hangs over the
rear or sides of the vehicle may
damage the vehicle. Load cargo
so that it rests evenly between
the crossrails, making sure to
fasten cargo securely.
To prevent damage or loss of cargo
when driving, check to make sure
cross rails and cargo are securely
fastened. Loading cargo on the roof
rack will make the vehicle's center
of gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden
braking or abrupt maneuvers,
otherwise it may result in loss of
control. If driving for a long distance,
on rough roads, or at high speeds,
occasionally stop the vehicle to
make sure the cargo remains in its
place. Do not exceed the maximum
vehicle capacity when loading the
vehicle. For more information on
vehicle capacity and loading, see
Vehicle Load Limits on page 8 ‑ 22 .
The roof rack crossrails can be
locked in four positions along the
roof rack side rails.
