which can be pulled forward to block
sun rays. The sunshade must be
opened and closed manually when
the sunroof is in the vent or fully
closed position.
Automatic Reversal System The sunroof has an automatic
reversal system that is only active
when the sunroof is operated in
express-close mode.
If an object is in the path while
express closing, the reversal system
will detect an object, stop, and open
the sunroof again.
If frost or other conditions prevent
closing, override the feature by
closing the sunroof 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.
If water is seen dripping into the
water drainage system, this is
normal.

See Power Outlets 0 127 and the

Features Cargo Tie-Downs
There are four cargo tie-downs in
the rear cargo area. These can be
used to strap cargo down and keep
it from moving inside the vehicle.
Convenience Net Use the convenience net, located in
the rear, to store small loads as far
forward as possible. The net should
not be used to store heavy loads. Roof Rack System
{ WarningIf 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 for additional
information.

Canada/Mexico-11349262) - 2018 - crc - 6/21/17
Storage 121CautionLoading 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. 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 0 200 .
A Center High-Mounted Stoplamp
(CHMSL) is located above the rear
window glass. Make sure items
loaded on the roof of the vehicle do
not block or damage the CHMSL.
