Roof Rack System

WARNING
If something is carried on top of
the vehicle that is longer or
wider than the roof rack — like
paneling, plywood, or a
mattress — the wind can catch it
while the vehicle is being driven.
The item being carried could be
violently torn off, and this could
cause a collision, and damage
the vehicle. Never carry
something longer or wider than
the roof rack on top of the vehicle
unless using a GM Certified
accessory carrier.
For vehicles with a roof rack, the
rack can be used to load items.
For roof racks that do not have
crossrails included, GM Certified
crossrails can be purchased as an
accessory. See your dealer/retailer
for additional information.
Notice: Loading cargo on the
roof rack that weighs more than
91 kg (200 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
crossrails 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 9‑12.
