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.
