belt GMC YUKON DENALI 2003 Workshop Manual

When the passenger sensing system has turned off the
passenger’s frontal air bag, the
off indicator will light
and stay lit to remind you that the air bag is
off.
The passenger sensing system is designed to turn off
the passenger’s frontal air bag when a rear facing infant
seat, a forward-facing child restraint or a booster seat
is detected. If the child restraint has been installed
and the on indicator is lit, turn the vehicle
off, remove
the child restraint from the vehicle and reinstall the
restraint following the child restraint manufacturer’s
directions and refer to Securing
a Child Restraint in the
Right Front Seat Position
on page 7-68 of this manual.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, secure the child in
the child restraint in a rear seat position in the vehicle
and check with your dealer.
The passenger sensing system is designed to enable
(may inflate) the right front passenger’s frontal air
bag anytime the system senses that a person of adult
size is sitting properly in the right front passenger’s seat.
When the passenger sensing system has allowed the
air bag to be enabled, the on indicator will light and stay
lit to remind you that the air bag is active. For
some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn
off the right front passenger’s
frontal air bag, depending upon the person’s seating
posture and body build. Everyone in your vehicle
who has outgrown child restraints should wear a safety
belt properly
- - whether or not there is an air bag
for that person.
If a person of adult-size is sitting in the right front
passenger’s seat, but the
off indicator is lit, it could be
because that person isn’t sitting properly in the seat. If
this happens, turn the vehicle
off and ask the person to
place the seatback in the full upright position, then sit
upright in the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about two
minutes. This will allow the system to detect that person
and then enable the passenger’s air bag.

Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired. Torn
or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Replacing Restraint System Parts
After a Crash
A crash can damage the restraini ystems in
your vehicle.
A damaged restraint system may
not properly protect the person using
it,
resulting in serious injury or even death in a
crash.
To help make sure your restraint
systems are working properly after a crash,
have them inspected and any necessary
replacements made as
soon as possible. If
you’ve had a crash, do
YOU need new belts or LATCH
system parts?
After a very minor collision, nothing may be necessary.
But
if the belts were stretched, as they would be if
worn during a more severe crash, then you need new
parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even
if the belt
or LATCH system wasn’t being used at the time of
the collision.
If an air bag inflates, you’ll need to replace air bag
system parts. See the part on the air bag system earlier
in this section.

Doors and Locks
Door Locks
doors can be dangerous.
Passengers - especially children - can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won’t open
it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors aren’t locked. So,
wear safety belts properly and lock the
doors whenever you drive.
vehicles may be unable to get out.
A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave
it.
CAUTION: (Continued)
Young children who get into unlocked
Outsiders can e ~ ily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.
There are several ways
to lock and unlock your vehicle.
To unlock the door from the outside, use the keyless
entry system
or the key.
To unlock the door from
the inside, slide the
manual lever
forward.
To lock the door, slide the

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your vehicle’s odometer works together with the driver information center. You can set
a personal trip
and business trip odometer. See “Trip Information” under
DIC Operation and Displays on page 3-43.
The odometer mileage can be checked without the
vehicle running. Simply press the trip stem
on the
instrument panel cluster.
If your vehicle ever needs a new odometer installed, the
new one will be set
to the correct mileage total of the
old odometer.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come
on for several seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds,
then it will flash for
several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come
on.
Notice: Do not operate the engine with the
tachometer in the shaded warning area, or engine
damage may occur.

If the word OFF or the off symbol is lit on the air bag
status indicator,
it means that the passenger sensing
system has turned
off the right front passenger’s frontal
air bag. See Passenger Sensing System on page
7 -8 7
for more on this, including important safety information.
If, after several seconds, all status indicator lights
remain on, or
if there are no lights at all, there may be a
problem with the lights or the passenger sensing
system. See your dealer for service.
__ -he ofl ..jdicator and the air bag readiness
light ever come on together, it means that
something may be wrong with the air bag
system.
If this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front passenger seat
may not have the protection of the frontal air
bag. See “Air Bag Readiness Light” in the
Index.
Charging System Light
The charging system light
will come on briefly when you turn on the ignition,
but the engine is
not
running, as a check to
show you it
is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system.
It could indicate
that you have problems with a generator drive belt, or
another electrical problem. Have it checked right
away. Driving while this light is on could drain your
battery.
When this light comes on the DIC will also display the
battery not charging message. See
DIC Warnings
and Messages
on page 3-52.
If you must drive a short distance with the light on, be
certain to turn
off all your accessories, such as the radio
and air conditioner.

For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealer
(GM Part No. 12344789).
The cut tape detection feature of your cassette tape
player may identify the cleaning cassette as a damaged
tape, in error. To prevent the cleaning cassette from
being ejected, use the following steps:
1.
2.
3.
4.
5.
Turn the ignition on.
Turn the radio
off.
Press and hold the CD TAPE button for five
seconds. The tape symbol on the display will flash
for two seconds.
Insert the scrubbing action cleaning cassette.
Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
After the cleaning cassette is ejected, the cut tape detection feature will be active again.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt
to
clean the tape head. This type of cleaning cassette will
not eject on its own. A non-scrubbing action cleaner
may not clean as thoroughly as the scrubbing type
cleaner. The use of a non-scrubbing action, dry-type
cleaning cassette is not recommended. After
you clean the player, press and hold the EJECT
button for five seconds to reset the CLN indicator.
The radio will display
--- to show the indicator was reset.
Cassettes are subject
to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.
Care of Your CDs and DVDs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen
a clean, soft cloth in a mild, neutral detergent solution
and clean it, wiping from the center to the edge.
Be sure never
to touch the side without writing when
handling discs. Pick up discs by grasping the outer
edges or the edge of the hole and the outer edge.
Care of Your CD Changer
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens
of the CD optics
with lubricants internal
to the CD mechanism.

Your Driving, the Road, and
Your Vehicle
Defensive Driving
The best advice anyone can give about driving is: Drive
defensively.
Please start with a very important safety device in your
vehicle: Buckle up. See Safety Belts: They Are for
Everyone on page
1-25.
Defensive driving really means “be ready for anything.”
On city streets, rural roads or freeways,
it means
“always expect the unexpected.”
Assume that pedestrians or other drivers are going
to
be careless and make mistakes. Anticipate what
they might do. Be ready for their mistakes.
Rear-end collisions are about the most preventable of
accidents. Yet they are common. Allow enough following
distance. It’s the best defensive driving maneuver,
in
both city and rural driving. You never know when
the vehicle in front of
you is going to brake or turn
suddenly.
Defensive driving requires that a driver concentrate on
the driving task. Anything that distracts from the
driving task
- such as concentrating on a cellular
telephone call, reading, or reaching for something on the
floor
- makes proper defensive driving more
difficult and can even cause a collision, with resulting
injury. Ask
a passenger to help do things like this, or pull
off the road in a safe place to do them yourself.
These simple defensive driving techniques could save
your life.
Drunken Driving
Death and injury associated with drinking and driving is
a national tragedy.
It’s the number one contributor to
the highway death toll, claiming thousands of victims
every year.
Alcohol affects four things that anyone needs to drive
a vehicle:
0 Judgment
Muscular Coordination
Vision
Attentiveness.
Police records show that almost half of all motor
vehicle-related deaths involve alcohol. In most cases,
these deaths are the result of someone who was
drinking and driving. In recent years, more than
16,000 annual motor vehicle-related deaths have been
associated with the use of alcohol, with more than
300,000 people injured.

Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds
are based on good weather and road conditions. Under
less favorable conditions you’ll want to go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try
to adjust your speed so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and find
a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front
of you. You
can avoid these problems by braking
- if you can stop
in time. But sometimes you can’t; there isn’t room.
That’s the time for evasive action
- steering around the
problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes.
See
Braking on page 4-6. It is better to remove as much
speed as you can from a possible collision. Then
steer around the problem, to the left or right depending
on the space available.
4-1

An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended
9 and 3 o’clock positions, you
can turn it a full
180 degrees very quickly without
removing either hand. But you have to act fast, steer
quickly, and just as quickly straighten the wheel
once you have avoided the object.
The fact that such emergency situations are always
possible is a good reason
to practice defensive driving
at all times and wear safety belts properly.
