Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle’s safety belts.
Q: What is the proper way to wear safety belts?
A: If possible, an older child should wear a
lap-shoulder belt and get the additional restraint a
shoulder belt can provide. The shoulder belt
should not cross the face or neck. The lap belt
should fit snugly below the hips, just touching the
top
of the thighs. It should never be worn over
the abdomen, which could cause severe or even
fatal internal injuries in a crash.
Accident statistics show that children are safer
if they
are restrained in the rear seat.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown
out of the vehicle. Older children need to use safety
belts properly.
If you have the choice, a child should sit in a seat that
has
a lap-shoulder belt to get the additional restraint
a shoulder belt can provide.

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 fit of the vehicle’s safety belt system. Some
booster seats have a shoulder belt positioner, and
some high-back booster seats have a five-point harness.
A booster seat can also help a child to see out the
window.

Top Strap Anchor Location
Yukon XL Denali models: A child restraint with a top
strap should only be used in the second or third
row. Don't use a child restraint with a top strap in the
front seat because there's no place to anchor the
top strap.

Yukon XL Denali Third Row Seat
An anchor loop bracket for a top strap is located at the
bottom rear of the seat cushion for each seating
position in the second row, for the center seating
position in the third row on bench seats.

Yukon Denali models: A child restraint with a top
strap should only be used in the second row or third row.
Don’t use a child restraint with a top strap in the right
front passenger’s position, because there’s no place to
anchor the top strap.
An anchor
loop bracket for a top strap is located at the
bottom rear of the seat cushion for each seating
position in the second row and in the outboard
passenger position in the third row for
50/50 split seats.

Lower Anchorages and Top Tethers
for Children (LATCH System)
Your vehicle ma.y have the LATCH system. If it does;
you’ll find anchors
(A) in the second row seats,
where the seatback meets the seat cushion.
To assist you in locating the lower anchors for this child
restraint system, each seating position with the
LATCH system will have a visible metal anchorage point
in the seat where the seatback meets the seat cushion. In order
to use
the system, you need either a
forward-facing child restraint that has attaching
points
(B) at its base and a top tether anchor (C), or a
rear-facing child restraint that has attaching points
(B),
as shown here.

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.

When Should an Air Bag Inflate?
Frontal Air Bags
The driver’s and right front passenger’s frontal air bags
are designed
to inflate in moderate to severe frontal
or near-frontal crashes. But they are designed to inflate
only
if the impact speed is above the system’s
designed “threshold level.”
In addition, your vehicle has “dual stage” frontal air
bags, which adjust the amount of restraint according to
crash severity. For moderate frontal impacts, these
air bags inflate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
If the front of your vehicle goes straight into a wall that
doesn’t move or deform, the threshold level for the
reduced deployment is about
10 to 16 mph
(16 to 25 km/h), and the threshold level for a full
deployment is about
20 to 25 mph (32 to 40 km/h).
The threshold level can vary, however, with specific
vehicle design,
so that it can be somewhat above
or below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will be
higher. The driver’s and right front passenger’s frontal
air bags are not designed
to inflate in rollovers, rear
impacts, or in many side impacts because inflation
would not help the occupant.
Seat Position Sensors
Vehicles with dual stage air bags are also equipped with
special sensors which enable the sensing system to
monitor
the position of both the driver and passenger
front seats. The seat position sensor provides information which is used
to determine if the air bags
should deploy at a reduced level or at full depoyment.
Side Impact Air Bags
Your vehicle may or may not have a side impact air
bag. See
Air Bag Systems on page 1-72. Side impact air
bags are designed
to inflate in moderate to severe
side crashes.
A side impact air bag will inflate if
the crash severity is above the system’s designed
“threshold level.” The threshold level can vary with
specific vehicle design. Side impact air bags are
not designed
to inflate in frontal or near-frontal impacts,
rollovers or rear impacts, because inflation would not
help the occupant.
A side impact air bag will only deploy
on the side of the vehicle that is struck.
Air Bag Systems
In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
For frontal air bags, inflation is determined by the angle
of the impact and how quickly the vehicle slows down

Outside Power Mirrors
The controls are located
on the driver’s door
armrest.
If the mirrors are accidently manually folded in, unfold
them using the mirror controls.
Do not unfold them
manually.
The mirrors also include a memory function which works
in conjunction with the memory seats. See
Memory
Seat on page 2-47 for more information.
Move the upper selector switch
to the left or right to
choose the mirror you want to adjust; then press
the dots located on the four-way control pad to adjust
the mirror.
To fold or unfold the mirrors, move the selector switch,
located above the mirror control,
to the middle
position. The mirror control will illuminate. Press the
right or left side of the mirror control to fold or unfold the
mirrors. You may notice the mirror glass adjust as the
mirrors fold in; this is normal. The mirror glass will
reposition itself once the mirrors are unfolded.
Outside Convex Mirror
Your passenger’s side mirror is convex. A convex
mirror’s surface is curved
so you can see more from the
driver’s seat.
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
