2010 GMC SIERRA DENALI Owners Manual

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.
For vehicles with a roof rack, the 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/retailer for additional
information.
Notice: Loading cargo on the roof rack that weighs
more than 91 kg (200 lbs) 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
Loading the Vehicle
on
page 5‑31.
.If small heavy objects are placed on the roof, cut a
piece of 3/8 inch plywood to fit inside the crossrails
and siderails to spread the load. Tie the plywood to
the siderail supports.
.Tie the load and secure it to the crossrails or the
siderail supports. Use the crossrails only to keep
the load from sliding. To move a crossrail, lift the
release lever up, on both sides of the rail. Then
slide the crossrail to the desired position balancing
the force side to side. Press the release lever
down on both sides of the rail, down to tighten it.
Try to slide the crossrail back and forth slightly to
make sure it is tight.
3-59

.To carry long items, move the crossrails as far
apart as possible. Tie the load to the crossrails and
the siderails or siderail supports. Also tie the load
to the bumpers, but do not tie the load so tightly
that the crossrails or siderails are damaged.
.After moving a crossrail, be sure it is securely
locked into the siderail.
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.
Rear Seat Armrest
Vehicles with a rear seat armrest have two cupholders.
Pull the armrest down from the rear seatback to access
the cupholders.
Cargo Management System
For vehicles with a cargo management system, it is
located in the bed of the truck. The system contains
three rails located on the front and sides of the bed.
The system has four adjustable cargo tie-downs, that
can be placed on the upper and lower slides of the rail.
To adjust a tie-down, pull the locator pin out and move
the tie-down to another location making sure the locator
pin lines up with a locator hole on the rail. The tie-down
pin may not be installed correctly if the pin does not line
up, turn it over and reinstall. The tie-down will not move
when the pin is completely installed. The maximum load
for each rail is 500 lbs (227 kg).
The rails are notched at each end which allows the
tie-downs to be removed and placed on another rail. To
remove, pull the locator pin out and slide the tie-down to
the end of the rail and pull back.
3-60

To remove or install cargo tie-downs at the front of the
bed, slide the corner cap towards the center of the bed
to expose the rail notches. To remove the corner cap,
pull either edge away from the rail.
To remove the system, loosen the toggle bolts on each
rail until they can be removed from the bed of the truck.
To replace the system, place the toggle bolts and rails
into their original locations and tighten them to a torque
setting of 12.5 ft lbs (17Y).
If the system is removed to install a bed liner, make
sure there is no bed liner material in the installation
points.
Notice: If cargo is tied down using the horizontal
slots on the top of the pickup box, the box could be
damaged. Using the horizontal slots on the top of
the pickup box for tie-down locations may cause
damage to the pickup box and would not be
covered by the vehicle warranty. Only use the
tie-down loops if the vehicle does not have the
cargo management system.Sunroof
On vehicles with a power sliding sunroof, the ignition
needs to be turned to RUN, or the Retained Accessory
Power (RAP) must be activated to open or close the
sunroof. When RAP is active, the sunroof will work for
10 minutes after the ignition is turned off, or until the
driver's door is opened. See Retained Accessory Power
(RAP)
on page 3‑24for more information.
There are two sunroof
switches located in the
overhead console above
the rearview mirror.
Vent : From the closed position, press the rear of the
passenger's side switch to vent the sunroof. To close
the sunroof, press and hold the front of the passenger's
side switch.
3-61

Manual-Open/Manual-Close :To open the sunroof
press and hold the rear of the driver's side switch until
the sunroof reaches the desired position. To close the
sunroof, press and hold the front of the driver's side
switch until the sunroof reaches the desired position.
When the sunroof is opened, an air deflector will
automatically raise. The air deflector will retract when
the sunroof is closed.
Express-Open/Express-Close : To express-open the
sunroof, fully press and release the rear of the driver's
side switch. The sunroof will open automatically. To stop
the sunroof partway, press the switch a second time. To
express-close the sunroof, fully press and release the
front of the driver's side switch. The sunroof will close
automatically. To stop the sunroof partway, press the
switch a second time.
The sunroof also has a sunshade which you can pull
forward to block sun rays. The sunshade must be
opened and closed manually. Anti-Pinch Feature :
If an object is in the path of the
sunroof while it is closing, the anti-pinch feature will
detect the object and stop the sunroof from closing at
the point of the obstruction. The sunroof will then open
halfway, and the air deflector will raise. To close the
sunroof once it has re-opened, refer to the
Express-Close or Manual-Close functions described
previously. If the sunroof is in the vent position, and
there is an object in the path of the sunroof when it
closing, the anti-pinch feature will detect the object and
stop the sunroof. To close the sunroof once it has
re-opened, refer to the Manual-Close or Express-Close
functions described previously.
Do not keep the sunroof open for long periods of time
while the vehicle is not in use. Debris can collect in the
tracks which can damage the sunroof operation, and
plug the water draining system.
