Cargo Tie-Downs
1. Convenience Net Retainers
2. Cargo Tie-Downs
The vehicle may be equipped with two
cargo tie-downs and two convenience net
retainers in the rear compartment.
Convenience Net
This vehicle may have a convenience net in
the rear of the vehicle. Attach it to the
convenience net retainers for storing small
loads.
Do not use the net to store heavy loads.
Roof Rack System
The vehicle may be 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
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(Continued)
Warning (Continued)
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)

Mexico-16540740) - 2023 - CRC - 6/16/22
Storage 79
.Without Sunroof: 50 kg (110 lb)
{Warning
Never load the roof rack with more
weight than specified in this section.
Loading cargo on the roof rack will make
the vehicle's center of gravity higher. To
avoid losing control of the vehicle, avoid
overloading, 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 0196.

Driving and Operating 231
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. Water
droplets 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 078.
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” underExterior Care 0319.
