2010 GMC SIERRA DENALI tailgate

Rear Vision Camera (RVC)
The rear vision camera displays a view of the area
behind the vehicle when the vehicle is shifted into
R (Reverse) on the inside rear view mirror or the
navigation screen, if equipped.
To clean the camera lens, located in the bezel for the
tailgate handle, rinse it with water and wipe it with a soft
cloth.
For more information, seeRear Vision Camera (RVC)
on page 3‑45.
Ultrasonic Parking Assist
This feature uses sensors on the rear bumper to detect
objects while parking the vehicle. It operates at speeds
less than 8 km/h (5 mph). URPA uses audio beeps to
provide distance and system information.
Keep the sensors on the vehicle's rear bumper clean to
ensure proper operation.
The system can be disabled by pressing the rear park
aid disable button located next to the radio.
SeeUltrasonic Rear Parking Assist (URPA)
on
page 3‑43for more information.
Power Outlets
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone.
There are two accessory power outlets on the
instrument panel, one inside the center floor console
and one on the rear of the center floor console.
The accessory power outlets are powered, even when
the ignition is in LOCK/OFF. Continuing to use power
outlets while the ignition is in LOCK/OFF may cause the
vehicle's battery to run down.
Universal Remote System
The Universal Home Remote System allows for garage
door openers, security systems, and home automation
devices to be programmed to work with these buttons in
the vehicle.

Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety belts
properly. It also tells you some things you should not do
with safety belts.
{WARNING:
Do not let anyone ride where a safety belt cannot
be worn properly. In a crash, if you or your
passenger(s) are not wearing safety belts, the
injuries can be much worse. You can hit things
inside the vehicle harder or be ejected from the
vehicle. You and your passenger(s) can be
seriously injured or killed. In the same crash, you
might not be, if you are buckled up. Always fasten
your safety belt, and check that your passenger(s)
are restrained properly too.
{WARNING:
People riding on the tailgate (if equipped) can
easily lose their balance and fall even when the
vehicle is operated at low speeds. Falling from a
moving vehicle may result in serious injuries or
death.
{WARNING:
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision,
people riding in these areas are more likely to be
seriously injured or killed. Do not allow people to
ride in any area of your vehicle that is not
equipped with seats and safety belts. Be sure
everyone in your vehicle is in a seat and using a
safety belt properly.
Your vehicle has indicators as a reminder to buckle your
safety belts. See Safety Belt Reminders on page 4‑30.

Lockout Protection
This feature protects you from locking the key in the
vehicle when the key is in the ignition and a front door
is open.
If the driver's side power door lock switch is pressed
when the driver's door is open and the key is in the
ignition, all of the doors will lock and then the driver's
door will unlock.
If the passenger's side power door lock switch is
pressed when the front passenger's door is open and
the key is in the ignition, all of the doors will lock and
then the front passenger's door will unlock.
Rear Doors
You can open your doors from the inside or outside.
Your vehicle may also have a feature which prevents
children from opening the rear doors. SeeRear Door
Security Locks
on page 3‑12for more information.
Tailgate
{WARNING:
It is extremely dangerous to ride on the tailgate,
even when the vehicle is operated at low speeds.
People riding on the tailgate can easily lose
their balance and fall in response to vehicle
maneuvers. Falling from a moving vehicle may
result in serious injuries or death. Do not allow
people to ride on the tailgate. Be sure everyone in
your vehicle is in a seat and using a safety belt
properly.
On vehicles with a lock on the tailgate, use the key to
lock or unlock the tailgate.
Open the tailgate by lifting up on its handle while pulling
the tailgate toward you.
To shut the tailgate, firmly push it upward until it latches.
After you put the tailgate back up, pull it back towards
you to be sure it latches securely.
3-13

Tailgate Removal
The tailgate can be removed to allow for different
loading situations. Although the tailgate can be removed
without assistance, you may want someone to assist
you with the removal to avoid possible damage to the
vehicle.
On vehicles with a rear vision camera, it must be
disconnected before removing the tailgate.
To remove the tailgate, do the following:
1. Raise the tailgateslightly and release
both retaining cable
clips. To release the
retaining cable clips, lift
the cable so it points
straight out. Lift the clip
over the bolt, and push
the cable forward then
rotate down. 2. With the tailgate about halfway open, lift the right
edge of the tailgate from the lower pivot.
On vehicles with the tailgate assist feature, raise
the tailgate nearly all the way to the closed position
prior to removing the left edge.
3. Move the tailgate to the right to release the left edge.
Reverse this procedure to reinstall the tailgate. Make
sure the tailgate is secure.

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the Ultrasonic Rear Parking Assist
(URPA) system, it operates at speeds less than
8 km/h (5 mph), and assists the driver with parking and
avoiding objects while in R (Reverse). The sensors on
the rear bumper are used to detect the distance to an
object up to 2.5 m (8 ft) behind the vehicle, and at least
25.4 cm (10 in) off the ground.
{WARNING:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision. It cannot
detect:
.Objects that are below the bumper,
underneath the vehicle, or if they are too close
or far from the vehicle
.Children, pedestrians, bicyclists, or pets.(Continued)
WARNING: (Continued)
If you do not use proper care before and while
backing; vehicle damage, injury, or death could
occur. Even with URPA, always check behind the
vehicle before backing up. While backing, be sure
to look for objects and check the vehicle's mirrors.
How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). A single tone sounds to
indicate the system is working.
URPA operates only at speeds less than
5 mph (8 km/h).
An obstacle is indicated by audible beeps. The interval
between the beeps becomes shorter as the vehicle gets
closer to the obstacle. When the distance is less than
30 cm (12 in) the beeps are continuous.
To be detected, objects must be at least 25.4 cm (10 in)
off the ground and below tailgate level. Objects must
also be within 2.5 m (8 ft) from the rear bumper. This
distance may be less during warmer or humid weather.
3-43

The system can be
disabled by pressing the
rear park aid disable
button located next to the
radio.
The indicator light will come on and PARK ASSIST OFF
displays on the Driver Information Center (DIC) to
indicate that URPA is off, see DIC Warnings and
Messages on page 4‑57.
Notice: If you use URPA while the tailgate is
lowered, it may not detect an object behind your
vehicle, and you might back into the object and
damage your vehicle. Always verify the tailgate is
closed when using URPA or turn off URPA when
driving with the tailgate lowered.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the messages PARK ASSIST OFF or PARK
ASST BLOCKED SEE OWNERS MANUAL will be
displayed on the DIC.
SERVICE PARK ASSIST : If this message occurs, take
the vehicle to your dealer/retailer to repair the system. PARK ASSIST OFF :
This message occurs if the driver
disables the system.
PARK ASST BLOCKED SEE OWNERS MANUAL :
This message can occur under the following conditions:
.The ultrasonic sensors are not clean. Keep the
vehicle's rear bumper free of mud, dirt, snow, ice
and slush. For cleaning instructions, see Washing
Your Vehicle on page 6‑108.
.The park assist sensors are covered by frost or
ice. Frost or ice can form around and behind the
sensors and may not always be seen; this can
occur after washing the vehicle in cold weather.
The message may not clear until the frost or ice
has melted.
.A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the tailgate during the
last drive cycle. Once the attached object is
removed and the tailgate is raised, URPA will
return to normal operation.
.A tow bar is attached to the vehicle.
.The vehicle's bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
.Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
