2009 GMC SIERRA tailgate

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.
{CAUTION:
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.
{CAUTION:
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.
{CAUTION:
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. SeeSafety Belt Reminders on page 3-36.

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. SeeRear
Vision Camera (RVC) on page 2-65for more information.
To remove the tailgate, do the following:
1. Raise the tailgate
slightly 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.

How the System Works
URPA comes on automatically when the shift lever
is moved into R (Reverse). The rear display briey
illuminates to indicate the system is working.
URPA operates only at speeds less than 5 mph
(8 km/h). If the vehicle is above this speed, the red light
on the rear display will ash.
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below tailgate level.
Objects must also be within 8 feet (2.5 m) from the
rear bumper. This distance may be less during warmer
or humid weather.
A single beep will sound the rst time an object is
detected between 40 inches (1 m) and 8 feet (2.5 m)
away. Beeping will occur continuously when the vehicle
is at 23 inches (0.6 m) or closer to an object.The following describes what will occur with the URPA
display as the vehicle gets closer to a detected object:
Description English Metric
amber light 8 ft 2.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights
and continuous beeping
for ve seconds23 in 0.6 m
amber/amber/red lights
ashing and continuous
beeping for ve seconds1 ft 0.3 m
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, seeDIC Warnings and
Messages on page 3-66for information about clearing
the message.
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 message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on
the rear URPA display when the shift lever is moved into
R (Reverse). This occurs under the following conditions:
The driver disables the system.
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 5-117.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the tailgate during the
last drive cycle, the red light may illuminate in the
rear display. Once the attached object is removed,
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.
If the system is still disabled, after driving forward
at least 15 mph (25 km/h), take the vehicle to your
dealer/retailer.

The camera does not display objects which are close
to either corner of the bumper or under the bumper.
The area displayed on the screen can vary according
to vehicle orientation or road conditions.
The following illustration shows the eld of view that the
camera provides.
