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

Cargo Management System
Lift the load floor to access the cargo
management system.
After storing items, make sure to properly
secure the load floor.
The cargo management system has a height
adjustment. Place the load floor on the
holders.
To access the spare tire, lift the load floor
and place it into the load floor holding slots.
SeeTire Changing 0294.
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 75 kg (165 lb) or hangs
over the rear or sides of the vehicle may
damage the vehicle. Do not load cargo
exceeding 75 kg (165 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.

84 Storage
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, seeVehicle
Load Limits 0181.

Driving and Operating 213
Do not use ACC when driving on steep hills
or when towing a trailer. ACC will not detect
a vehicle in the lane while driving on steep
hills. If the brakes are applied, ACC
disengages.
Disengaging ACC
There are three ways to disengage ACC:
.Step lightly on the brake pedal.
.Press*.
.Press5.
Erasing Speed Memory
The ACC set speed is erased from memory if
5is pressed or if the ignition is turned off.
Weather Conditions Affecting ACC
If the interior temperature is extremely
high, the instrument cluster may indicate
that ACC is temporarily unavailable. This can
be caused by extreme hot weather
conditions with direct sunlight on the front
camera. ACC will return to normal operation
once the cabin temperature is lower.
Conditions that are associated with low
visibility, such as fog, rain, snow, or road
spray, may limit ACC performance. Waterdroplets from rain or snow that remain on
the windshield may also limit ACC’s ability
to detect objects.
{Warning
Camera visibility may be limited and the
ACC system may not work properly if the
windshield is not clear. Do not use ACC if
moisture is present on the inside of the
windshield or the windshield washer is
used in cold weather. Turn on the front
defroster and make sure the windshield is
clear before using ACC. Before driving,
check that the windshield wipers are in
good condition and replace them if worn.
Lighting Conditions Affecting ACC
The ACC front camera can be affected by
poor lighting conditions, and ACC may have
limited performance when:
.There are changes in brightness, such as
entering and exiting tunnels, bridges, and
overpasses.
.Low sun angles cause the camera to not
detect objects, or it is more difficult to
detect objects in the same traffic lane.
.Lighting is poor in the evening or early
morning
.There are multiple changes in brightness
or shadows along the vehicle roadway.
.In a tunnel without the headlamps on,
or in a tunnel when there is a vehicle in
front that does not have its taillamps on.
.Subjected to strong light from opposing
lane traffic in the front of the vehicle,
such as high-beam headlamps from
oncoming traffic.
Accessory Installations and Vehicle
Modifications
Do not install or place any object around
the front camera windshield area that would
obstruct the front camera view.
Do not install objects on top of the vehicle
that overhang and obstruct the front
camera, such as a canoe, kayak, or other
items that can be transported on a roof rack
system. See
Roof Rack System 083.
Do not modify the hood, headlamps, or fog
lamps, as this may limit the camera’s ability
to detect an object.
