2003 GMC YUKON DENALI ecu

Second Row
The center seat position in the second row has a
lap-shoulder belt which works the same way as the
safety belt in the rear outside seat positions. For
instructions on how to secure a child restraint using a
lap-shoulder belt see Securing a Child Restraint in
a Rear Outside Seat Position on page
1-63.
Third Row
The center seat position in the third row has a lap belr.
Be sure to follow the instructions that came with the
child restraint. Secure the child in the child restraint
when and as the instructions say.
See Top Strap on page
1-57 if the child restraint
has one.
1. Make the belt as long as possible by tilting the latch
plate and pulling it along the belt.
2. Put the restraint on the seat.
3. Run the vehicle’s safety belt through or around the
restraint. The child restraint instructions will show
you how.

4. Buckle the belt. Make sure the release button is
positioned
so you would be able to unbuckle the
safety belt quickly
if you ever had to.
5. T3 tighten the belt, pull its free end whi!e you push
down on the child restraint. If you’re using a
forward-facing child restraint, you may find it helpful
to use your knee to push down on the child
restraint
as you tighten the belt.
6. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle’s
safety belt. It will be ready to work for an adult or
larger child passenger.

Securing a Child Restraint in the Right Front Seat Position
Your vehicle has a right front passenger air bag. A rear
seat is a safer place
to secure a forward-facing child
restraint. Unless your vehicle has the passenger sensing
system, never put a rear-facing child restraint in this
seat. Here’s why:
A vnnnnu nn a rear-facing child restraint Call be
seriously injured or killed
if the right front
passenger’s air bag inflates. This is because
the back of the rear-facing child restraint
would be very close to the inflating air bag.
Always secure a rear-facing child restraint in a rear seat unless the air bag
is off.
If your vehicle has the passenger sensing system and
you need
to secure a rear-facing child restraint in
the right front passenger’s seat, the passenger’s air bag
must be
off. See Passenger Sensing System on
page
7-87 and Passenger Air Bag Status Indicator on
page
3-32 for more information on this including
important safety information.

A child in a rear-facing child restraint can be
seriously injured or killed if the right front passenger’s air bag inflates. This
is because
the back of the rear facing child restraint
would be very close
to the inflating air bag.
Be sure the air bag is
off before using a
rear-facing child restraint
in the right front seat
position.
Even though the passenger sensing system is
designed to turn
off the passenger’s frontal air
bag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an air bag will not deploy under some unusual circumstance, even
though
it is turned off. General Motors
therefore recommends that rear-facing child restraints be secured in the rear seat whenever
possible, even
if the air bag is off.
You’ll be using the lap-shoulder belt. See Top Strap on
page
1-57 if the child restraint has one. Be sure to
follow the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Because your vehicle has a right front passenger
air bag, always move the seat as far back as it will
go before securing a child restraint,
if you need
to secure a forward-facing child restraint in the right
front seat position. See
Power Seats on page 1-3.
If your vehicle has the passenger sensing
system and you are using a rear-facing child
restraint in this seat, make sure the frontal air bag
is
off. See Passenger Sensing System on
page
1-8 1.
When the passenger sensing system has turned off
the right front passenger’s frontal air bag, the off
indicator on the inside rearview mirror will light and
stay lit when you turn the ignition to RUN or
START.
2. Put the restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show
you how.
1-69

6. To tighten the belt, feed the shoulder belt back into
the retractor while you push down on the child
restraint. If you are using a forward-facing child
restraint, you may find it helpful to use your knee to
push down on the child restraint as you tighten the
belt. You should not be able to pull more of the belt
out of the retractor once the lock has been set.
7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If your vehicle has the passenger sensing system
and you’re using a rear-facing child restraint in this
seat, check to be sure the right front passenger’s
frontal air bag is off before you begin to drive.
If the
air bag has been turned off the
off indicator will
light and stay lit when the key is turned to RUN or
START.
If the on indicator is lit, the passenger’s frontal air
bag has not been turned
off. If this ever happens,
turn off the vehicle, unbuckle the safety belt
and perform the steps to install the rear-facing
restraint again. After restarting the vehicle,
if the air
bag still doesn’t turn off, install the infant restraint
in
a rear seat position of the vehicle and have your
vehicle serviced as soon as possible.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.

An,,ne who is up against, or very close to,
any air bag when
it inflates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its air bag system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly
in your vehicle. To read how,
see the part of this manual called “Older
Children” or
“Infants and Young Children”.
There is a air bag readiness light on the
instrument panel cluster,
which shows the air
bag symbol. The
system checks the air bag electrical system for
malfunctions. The light tells you
if there is an electrical
problem. See
Air Bag Readiness Light on page 3-31
for more information.
Where Are the Air Bags?
The driver’s frontal air bag is in the middle of the
steering wheel.

Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a passenger
sensing system. The indicator will be visible when you
turn your ignition key
to START or RUN. The words ON
and OFF or the symbol for on and off, will be visible on
the rearview mirror during the system check. When the
system check
is complete, either the word ON or the word
OFF, or the symbol for on or the symbol for off will be
visible. See Passenger
Air Bag Status Indicator on
page 3-32. If your rearview mirror doesn’t have either of
the indicators pictured, then your vehicle doesn’t have the
passenger sensing system.

The passenger sensing system will turn off the right
front passenger’s frontal air bag under certain
conditions. The driver’s air bag and the side air bags
are not part
of the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence of
a properly-seated occupant and determine
if the
passenger’s frontal air bag should be enabled
(may inflate) or not.
Accident statistics show that children are safer
if they
are restrained in the rear rather than the front seat.
General Motors, therefore, recommends that child
restraints be secured in a rear seat including an infant
riding in a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding in a
booster seat. Never put a child in rear facing child
