tailgate CHEVROLET AVALANCHE 2008 2.G Owners Manual

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 he or she cannot
wear a safety belt properly. If you are in a
crash and you are not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle harder or be ejected
from it and 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 3-34.

using the power door lock switch, or the Remote
Keyless Entry (RKE) transmitter, if the vehicle
has one.

Midgate®
{CAUTION:
It can be dangerous to drive with the cargo
area covered and the tailgate and the Midgate®
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the cargo
covers on and the tailgate and Midgate
®
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the Midgate
®:
Make sure all windows are shut.
Turn the fan on your heating or cooling
system to its highest speed on the setting
that brings in outside air. This will force
outside air into your vehicle. SeeDual
Automatic Climate Control System on
page 3-24.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-48.
2-12

Tailgate
{CAUTION:
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.
Use the Remote Keyless Entry (RKE) transmitter or
power door lock switch to lock and unlock the tailgate.
Open the tailgate by lifting up on its handle while pulling
the tailgate toward you.
To shut the tailgate, push it rmly upward until it
latches. Push and pull on the tailgate to be sure it is
latched securely.
Tailgate Removal
The tailgate is not to be removed. This may cause
damage to electrical connector resulting in loss
of lock/unlock and rear vision camera function.
Power Running Boards
Your vehicle may have power running boards.
The power running boards automatically extend from
beneath the vehicle on the side in which the door
has been opened. Once the door is closed, the running
boards will automatically move back under the vehicle
after a brief delay. The vehicle must not be moving
for the running boards to extend or retract.
The switch used to disable
the power running boards
is located on the center
console below the climate
control system.
The running boards cannot be disabled in the extended
position.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however,
they do not make it impossible to steal.
Content Theft-Deterrent
Your vehicle has a content theft-deterrent alarm system.
This is the security light.
To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote Keyless Entry (RKE)
transmitter or the power door lock switch. The
security light will come on to inform the driver the
system is arming. If a door is open when the doors
are locked, the security light will ash.If the delayed locking feature is turned on, the
theft-deterrent system will not start the arming
process until the last door is closed and the delay
timer has expired. SeeDelayed Locking on
page 2-10.
3. Close all doors. The security light should go off
after about 30 seconds. The alarm is not armed
until the security light goes off.
The content theft deterrent system does not
sense if the midgate or tailgate are open or ajar,
therefore, vehicle contents may not be protected
if the midgate is left open or ajar.
If a locked door is opened without using the RKE
transmitter, a ten second pre-alarm will occur. The horn
will chirp and the lights will ash. If the key is not placed
in the ignition and turned to START or the door is not
unlocked by pressing the unlock button on the RKE
transmitter during the ten second pre-alarm, the alarm
will go off. Your vehicle’s headlamps will ash and the
horn will sound for about two minutes, then will turn off
to save the battery power.

The display is located
above the rear window and
can be seen by looking
over your right shoulder.
URPA uses three color-coded lights to provide distance
and system information.
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 20 inches (0.5 m) and 8 feet (2.5 m)
away. Beeping will occur for a short time when the
vehicle is closer than 1 foot (0.3 m) from the 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 23 in 0.6 m
amber/amber/red lights
ashing and beep for
three seconds1 ft 0.3 m
2-59

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 PARKING
ASSIST OFF displays
on the
Driver Information Center (DIC) to indicate that URPA is
off, seeDIC Warnings and Messages on page 3-59
for 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 PARKING 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 parking brake pedal is depressed.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow, ice and
slush. For cleaning instructions, seeWashing Your
Vehicle on page 5-102.
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.
