If frost or other conditions prevent
closing, override the feature by
closing the sunroof or power
sunshade in manual mode. To stop
movement, release the switch.
Dirt and debris may collect on the
sunroof seal or in the track. This
could cause an issue with sunroof
operation or noise. It could also plug
the water drainage system.
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.

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.
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.

Storage 97
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 0174.
