Hummer 2010 H3 - Manual (Page 112)

4-4 Storage
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 HUMMER
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, HUMMER
Certified crossrails can be
purchased as an accessory.
See your dealer for additional
information.
Notice: Loading cargo on the
roof rack that weighs more than
113 kg (250 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 9‑27.
