This information replaces the
information under“Roof Rack
System” found in the Storage
Section of the owner ’s manual.
The vehicle is equipped with
side-rails for a roof rack system.
Cargo must be secured with
properly installed cross rails and
other accessories designed to carry
cargo. These can be purchased
from your dealer.
{Warning
Before driving and occasionally
during a trip, check that cargo is
securely fastened, rests evenly
between the cross rails and does
not block the vehicle's lamps or (Continued)
Warning (Continued)
windows. Never load cargo
directly on the roof of the vehicle
or allow cargo to hang over the
rear or sides of the vehicle. Never
load cargo without first properly
installing cross rails and other
accessories designed to carry
cargo. Personal injury, death or
damage to the vehicle or other
property may occur.
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.
Cargo Weight Limits
Do not exceed the maximum cargo
weight for the roof rack system,
including the weight of the cross
rails and any other accessories
used to carry the cargo such as bike
racks or roof boxes.
For all trim levels except Denali, the
maximum cargo weight that can be
loaded onto the roof rack system is
100 kg (220 lb).
For Denali, the maximum weight is
as follows:
Front-Wheel Drive
.With Sunroof: 40 kg (88 lb)
. Without Sunroof: 65 kg (143 lb)

All-Wheel Drive
.With Sunroof: 25 kg (55 lb)
. Without Sunroof: 50 kg (110 lb)
{Warning
Never load the roof rack with
more weight than specified in this
section or in the instructions that
came with cross rails and other
roof rack accessories, whichever
is less. Loading cargo on the roof
rack will make the vehicle's center
of gravity higher. To avoid losing
control of the vehicle, avoid high
speeds, sudden starts, sharp
turns, sudden braking, or abrupt
maneuvers when carrying cargo
on the roof rack. The weight of any cargo carried on
the roof rack system must be
included in calculating the loaded
weight of the vehicle. Do not exceed
the maximum vehicle capacity when
loading the vehicle, including cargo
carried on the roof rack system,
passengers and cargo carried in the
vehicle. For more information on
vehicle capacity and loading, see
Vehicle Load Limits.

When the sunroof is opened, an air
deflector will automatically raise.
The air deflector will retract when
the sunroof is closed.
The sunroof cannot be opened or
closed if the vehicle has an
electrical failure.
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 the object, stop, and
open the sunroof slightly.
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.

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 with side rails or docking
stations, GM certified crossrails can
be purchased as an accessory and
used to load items. 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.
1. Side Rails
2. Docking Stations
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 0175.

Driving and Operating 229
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 093.
Do not modify the hood, headlamps,
or fog lamps, as this may limit the
camera’s ability to detect an object.
Cleaning the Sensing System
The camera sensor on the
windshield behind the rearview
mirror can become blocked by
snow, ice, dirt, mud, or debris. This
area needs to be cleaned for ACC
to operate properly. The vehicle headlamps may need to
be cleaned due to dirt, snow, or ice.
Objects that are not illuminated
correctly may be difficult to detect.
If ACC will not operate, regular
cruise control may be available. See
“Switching Between ACC and
Regular Cruise Control”
in this
section. Always consider driving
conditions before using either cruise
control system.
For cleaning instructions, see
“Washing the Vehicle” under
Exterior Care 0356.
