(if equipped) in Suburban/Yukon XL models also folds
down to create more cargo space.
To fold the seatback down, pull up on the release lever,
labeled 1, located on the rear of the seatback, then push
the seatback forward.To return the seat to the passenger position, pull up on
the release lever and then pull up on the seatback until
it locks into the upright position. Push forward on the
seatback to make sure it is locked into position.
If still more cargo space is desired, the third seat can
also be folded and tumbled forward by using the lever,
labeled 2. To return the seats to their original position,
reverse the above steps.
Fold and Tilt Feature (Suburban/Yukon XL
Third Seat)
Once the third seatback has been folded down, the
entire seat can be tilted forward to create a flat load
floor. To do this, you will need to enter the rear cargo
area of the vehicle. Make sure the head restraints have
been lowered completely.
With the seat folded, unlatch the seat from the floor by
pulling up on the lever located under the carrying handle
at the rear of the seat labeled 2. Lift the rear of the seat
up, off of the floor. You will not be able to unlatch the
seat from the floor unless the seatback is folded down.
Tilt the seat fully forward and secure it in place using
the support rod located on the underside of the seat,
passenger side. Make sure the support rod pin is fully
engaged in the lock.

Push and pull on the seat, making sure that the support
rod is holding it firmly in place. Use the seat in this
position only when necessary for additional cargo space.
CAUTION:
If the support rod isn't properly engaged, the
folded third row seat could come loose in a
sudden stop or crash. That could cause injury to
people and damage to your vehicle. Always be
sure the support rod is properly engaged when
the third row seat is folded forward.
To return the seat to its seating position, push forward
on the seat and release the support lock rod. Secure the
support rod in its stored position on the underside of the
seat. Lower the seat to the floor and let the seat drop into
place. Lift up on the carrying handle to make sure the
seat is locked in place.
Return the seatback to the upright position by pulling
up on the release lever labeled 1 before the back can be
folded upright. Pull the seatback forward to make sure it
is locked into place.Removing the Third Row Seats

CAUTION:
A seat that isn't locked into place properly can
move around in a collision or sudden stop. People
in the vehicle could be injured. Be sure to lock
the seat into place properly when installing it.
Safety Belts: They're 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.
And it explains the air bag system.
CAUTION:
Don't let anyone ride where he or she can't wear
a safety belt properly. If you are in a crash and
you're not wearing a safety belt, your injuries
can be much worse. You can hit things inside the
vehicle or be ejected from it. You can 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 passengers' belts
are fastened properly too.

How to Wear Safety Belts Properly
Adults
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, see the part of this manual called
ªChildren.º Follow those rules for everyone's protection.
First, you'll want to know which restraint systems your
vehicle has.
We'll start with the driver position.
Driver Position
This part describes the driver's restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here's how to
wear it properly.
1. Close and lock the door.
2. Adjust the seat (to see how, see ªSeatsº in the Index)
so you can sit up straight.
3. 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.
4. Push the latch plate into the buckle until it clicks.

1-31 How the Air Bag Systems Work
Where are the air bags?
The driver's frontal air bag is in the middle of the
steering wheel.
The right front passenger's frontal air bag is in the
instrument panel on the passenger's side.
The driver's side impact air bag is in the side of the
driver's seatback closest to the door.

1-32
The right front passenger's side impact air bag is in the
side of the passenger's seatback closest to the door.
CAUTION:
If something is between an occupant and an
air bag, the bag might not inflate properly or
it might force the object into that person. The
path of an inflating air bag must be kept clear.
Don't put anything between an occupant and an
air bag, and don't attach or put anything on the
steering wheel hub or on or near any other air
bag covering and don't let seat covers block the
inflation path of a side impact air bag.

1-33
When should an air bag inflate?
The driver's and right front passenger's frontal air bags
are designed to inflate in moderate to severe frontal or
near
-frontal crashes. The frontal air bags are designed
to inflate only if the impact speed is above the system's
designed ªthreshold level.º If your vehicle goes
straight into a wall that doesn't move or deform, the
threshold level is about 9 to 16 mph (14 to 26 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, side impacts, or rear impacts,
because inflation would not help the occupant.
The side impact air bags are designed to inflate in
moderate to severe side crashes involving a front door.
A side impact air bag will inflate if the crash severity
is above the system's designed ªthreshold level.º
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.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
in frontal and near
-frontal impacts. For side impact air
bags, inflation is determined by the location and severity
of the impact.
The air bag system is designed to work properly under
a wide range of conditions, including off
-road usage.
Observe safe driving speeds, especially on rough terrain.
As always, wear your safety belt. See ªOff
-Road
Drivingº in the Index for more tips on off
-road driving.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For both
frontal and side impact air bags, the sensing system
triggers a release of gas from the inflator, which inflates
the air bag. The inflator, air bag and related hardware
are all part of the air bag modules inside the steering
wheel, instrument panel and the side of the front
seatbacks closest to the door.

1-34
How does an air bag restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The air bag supplements the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant's upper body,
stopping the occupant more gradually. But the frontal
air bags would not help you in many types of collisions,
including rollovers, rear impacts, and side impacts,
primarily because an occupant's motion is not toward
the air bag. Side impact air bags would not help you
in many types of collisions, including frontal or near
frontal collisions, rollovers, and rear impacts, primarily
because an occupant's motion is not toward those air
bags. Air bags should never be regarded as anything
more than a supplement to safety belts, and then only in
moderate to severe frontal or near
-frontal collisions for
the driver's and right front passenger's frontal air bags,
and only in moderate to severe side collisions for the
driver's and right front passenger's side impact air bags.What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module
-- the
steering wheel hub for the driver's air bag, the instrument
panel for the right front passenger's bag, the side of the
seatback closest to the door for the driver and right front
passenger's side impact air bags
-- will be hot for a short
time. The parts of the bag that come into contact with you
may be warm, but not too hot to touch. There will be
some smoke and dust coming from the vents in the
deflated air bags. Air bag inflation doesn't prevent the
driver from seeing or being able to steer the vehicle,
nor does it stop people from leaving the vehicle.
CAUTION:
When an air bag inflates, 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 inflates, then get fresh air
by opening a window or a door.

1-35
In many crashes severe enough to inflate an 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 inflate only once. After an
air bag inflates, you'll need some new parts for your
air bag system. If you don't get them, the air bag
system won't be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for
your vehicle covers the need to replace other parts.

Your vehicle is 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, when
the system commands air bag inflation and driver's
safety belt usage at deployment. Some modules also
record speed, engine rpm, brake and throttle data.

Let only qualified technicians work on your air bag
systems. Improper service can mean that an air
bag system won't 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, or the air
bag covering on the driver's and right front
passenger's seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right
front passenger's air bag, or both the air bag
module and seatback for the driver's and right
front passenger's side impact air bag. Do not
open or break the air bag coverings.
