Periodically open the sunroof and
remove any obstacles or loose debris.
Wipe the sunroof seal and roof sealing
area using a clean cloth, mild soap,
and water. Do not remove grease from
the sunroof.

Cargo Tie-Downs
The vehicle has four cargo tie-downs
in the rear compartment.
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 (Continued)
Warning (Continued)
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.
If equipped, the roof 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.
Caution
Loading cargo on the roof rack that
weighs more than 100 kg (220 lb) or
hangs over the rear or sides of the
vehicle may damage the vehicle. Do
not load cargo exceeding 100 kg
(220 lbs) and always load cargo so
that it rests evenly between the
crossrails and does not block the
vehicle lamps or windows. Fasten
the 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
