2004 GMC Sierra Denali Owner ManualM

Rear Seat Passengers
It's very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in the
rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who aren't safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.
Rear Seat Outside Passenger Positions
Lap-Shoulder Belt
The positions next to the windows have lap-shoulder
belts. Here's how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
1-24

A forward-facing child seat (C-E) provides restraint for
the child's body with the harness and also sometimes
with surfaces such as T-shaped or shelf-like shields.A booster seat (F-G) is a child restraint designed to
improve the ®t of the vehicle's safety belt system. Some
booster seats have a shoulder belt positioner, and
some high-back booster seats have a ®ve-point harness.
A booster seat can also help a child to see out the
window.

{CAUTION:
When an air bag in¯ates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
can't get out of the vehicle after an air bag
in¯ates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an air bag deployment, you
should seek medical attention.
In many crashes severe enough to in¯ate the air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
·Air bags are designed to in¯ate only once. After
they in¯ate, you will need some new parts for
your air bag system. If you do not get them, the air
bag system will not be there to help protect you
in another crash. A new system will include air bagmodules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
·Your vehicle is equipped with electronic frontal
sensors which help the sensing system distinguish
between a moderate and a more severe frontal
impact. Your vehicle is also equipped with a crash
sensing and diagnostic module, which records
information about the frontal air bag system. The
module records information about the readiness of
the system and when the system commands air
bag in¯ation. It records the status of the driver's
safety belt usage in a crash in which the air
bag deploys or a crash in which the air bag nearly
deploys. The module also records speed, engine
rpm, brake and throttle data.
·Let only quali®ed technicians work on your air bag
systems. Improper service can mean that an air
bag system will not work properly. See your dealer
for service.
Notice:If you damage the covering for the driver's
or the right front passenger's air bag, the bag
may not work properly. You may have to replace the
air bag module in the steering wheel or both the
air bag module and the instrument panel for
the right front passenger's air bag. Do not open or
break the air bag coverings.

could operate the power windows or other
controls or even make the vehicle move. The
children or others could be badly injured or
even killed. Do not leave the keys in a vehicle
with children.
2-2

Windows
{CAUTION:
Leaving children, helpless adults, or pets in a
vehicle with the windows closed is dangerous.
They can be overcome by the extreme heat
and suffer permanent injuries or even death
from heat stroke. Never leave a child, a
helpless adult, or a pet alone in a vehicle,
especially with the windows closed in warm or
hot weather.
2-13

Power Windows
A power window control is located on the inside of each
front door.The driver's door has a switch for the passenger
window as well. Your power windows will work when the
ignition has been turned to ACCESSORY or RUN or
when Retained Accessory Power (RAP) is active.
See ªRetained Accessory Powerº under
Ignition
Positions on page 2-18.
Press the rear of the switch with the power window
symbol on it to lower the window or press the front of
the switch to raise the window.
Express-Down Windows
The driver and passenger windows also has an express
down feature that allows the windows to be lowered
without holding the switch. Press and hold the front edge
of the window switch for one second to activate the
express down mode. The express down mode can be
canceled at any time by pulling up on the switch.
To open the window partway, lightly tap the switch until
the window is at the desired position.
2-14

Swing-Out Windows
To open a rear swing-out
window, ¯ip the latch open
and swing the glass out.
The latch will catch when the window is fully open and it
will also hold it in the open position.
Sun Visors
To block out glare, you can swing down the top and
bottom visors. You can also swing the bottom visor from
side-to-side. The visors may also have an extension
that can be pulled out for additional glare protection.
Illuminated Visor Vanity Mirrors
Your vehicle may have this feature. If it does, pull the
sun visor down and lift the mirror cover to turn on
the lamps. There is a slide switch to adjust the intensity
of the lamps.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
2-15

Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window
and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the security message to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound and the headlamps do not
¯ash, you may have the feature turned off. See
DIC
Operation and Displays on page 3-46for more
information.
Passlockž
Your vehicle is equipped with the
Passlockžtheft-deterrent system.
Passlock
žis a passive theft-deterrent system.
Passlockženables fuel if the ignition lock cylinder is
turned with a valid key. If a correct key is not used or the
ignition lock cylinder is tampered with, fuel is disabled.
If the engine stalls and the security light ¯ashes,
wait until the light stops ¯ashing before trying to restart
the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock
žsystem is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
žat this
time. You may also want to check the fuse. See
Fuses and Circuit Breakers on page 5-105. See your
dealer for service.
In an emergency, call the GM Roadside Assistance
Center. See
Roadside Assistance Program on page 7-6.
