To unlatch the seat from the
back of the floor, pull up on
the release lever labeled 2
at the rear of the seat and
lift the rear of the seat up
from the floor.
Pull on the release lever located in the lower middle to
unlatch the seat from the front of the floor and pull the
seat out. Use one hand on the release lever and the other
on the handle to pull the seat out.
Suburban/Yukon XL: If your vehicle has third row
seating, it can be taken out for more cargo space.
To remove the seat, fully open the rear doors and enter
the rear of the vehicle.Fold the seatback forward into the seat cushion by using
the lever labeled 1. The seat cannot be removed unless
the seatback is folded.
To unlatch the seat from the floor, pull up on the release
lever labeled 2 at the rear of the seat and lift the rear of
the seat up, off of the floor.
Pull on the strap at the rear of the seat to release the
front seat latches. Then, pull the seat straight back,
towards the rear of the vehicle and remove it. There are
wheels at the front of the seat to assist you.
Replacing the Rear Seat (Third Row Seats)
Utility: To put the seat back in, place the front of
the seat on the load floor facing towards the front of
the vehicle. Slide the wheels into the slots on the floor
and lock into place using the hooks there. Once the
latches are engaged pull on lever 3 to let the seat drop
into place. Release the lever labeled 1 to return the seat
to its upright position. Push and pull on the seat to make
sure it is locked into place.

Suburban/Yukon XL: To put the seat back in,
place the front of the seat on the load floor, facing the
front of the vehicle. While holding the rear of the seat
up use the wheels on the front of the seat to roll it
towards the seat hooks in the floor. When the latches
are engaged in the hooks, let the seat drop into place.
Lift up on the carrying handle to make sure the seat is
locked in place.
Raise the seatback into the upright position. Push and
pull on the seat to make sure it is locked into place.
The seatback cannot be raised to the upright position
unless the seat is secured to the floor.
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.

1-17 Why Safety Belts Work
When you ride in or on anything, you go as fast as it goes.
Take the simplest vehicle. Suppose it's just a seat on wheels.
Put someone on it.

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.
Page 45 of 407
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.

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.
