2005 Chevrolet Avalanche Owner ManualM

Horizontal Control:This control adjusts the seat
cushion.
Raise or lower the front of the seat by raising or
lowering the forward edge of the control. Raise or
lower the rear of the seat by raising or lowering the
rear edge of the control.
Move the seat forward or rearward by moving the
whole control toward the front or toward the rear of
the vehicle.
Lower or raise the entire seat cushion by moving the
whole control up or down.
Vertical Control:This control adjusts the seatback.
Move the reclining front seatback rearward or forward by
moving the control toward the rear or the front of the
vehicle. This adjusts the angle of the seatback.
For more information on the reclining seatbacks, see
Reclining Seatbacks on page 1-5.
Your vehicle may have a memory function which allows
seat settings to be saved and recalled. SeeMemory
Seat on page 2-82for more information.
Power Lumbar
If your vehicle has power
lumbar adjustment, you
can use it to increase
or decrease lumbar
support in the lower
seatback. The control is
located on the outboard
side of the seat cushion.
To increase support in the lower back area, press
and hold the front of the control. Let go of the
control when the lower seatback reaches the
desired level of support.
To decrease support in the lower back area, press
and hold the rear of the control. Let go of the
control when the lower seatback reaches the
desired level of support.
1-3

Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.
The rear seat head restraints in your vehicle are
adjustable. They work the same as the front seat head
restraints.
Rear Seats
Rear Seat Operation
The rear seat is a 60/40 split rear seat that can be
folded to give you more cargo space and access to the
folding midgate. SeeMidgate on page 2-11for more
information on operation of the folding midgate.
To fold either side of the seat do the following:
1. Push the rear head restraints all the way down.
2. Pull the seat loop
located where the
seatback and seat
cushion meet. The seat
cushion will release and
allow you to tilt it toward
the front of the vehicle.
1-7

3. Grasp the seatback and pull it toward the front of
the vehicle. Push it down until it is at. You may
have to move the front seats forward slightly to
do this.
4. Repeat the procedure for the other side.
To return the seats to the normal position, pull the
seatback up and fold the seat cushion down.
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it is
locked.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted will not provide
the protection needed in a crash. The person
wearing the belt could be seriously injured.
After raising the rear seatback, always check
to be sure that the safety belts are properly
routed and attached, and are not twisted.
1-8

{CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can not properly spread the impact
forces. In a crash, the two children can be
crushed together and seriously injured. A belt
must be used by only one person at a time.
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A:If the child is sitting in a rear seat outside position,
move the child toward the center of the vehicle.
If the child is sitting in the center position, move the
child toward the safety belt buckle. In either
case, be sure that the shoulder belt still is on the
child’s shoulder, so that in a crash the child’s upper
body would have the restraint that belts provide.
SeeRear Safety Belt Comfort Guides for Children
and Small Adults on page 1-26.
If the child is so small that the shoulder belt is still
very close to the child’s face or neck, you might
want to place the child in a seat that has a lap belt,
if your vehicle has one.
1-30

{CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child’s
hip bones are still so small that the vehicle’s
regular safety belt may not remain low on the
hip bones, as it should. Instead, it may settle
up around the child’s abdomen. In a crash, the
belt would apply force on a body area that is
unprotected by any bony structure. This alone
could cause serious or fatal injuries. Young
children always should be secured in
appropriate child restraints.
Child Restraint Systems
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed
to restrain or position a child on a continuous at
surface. Make sure that the infant’s head rests toward
the center of the vehicle.
1-35

How Does an Airbag 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 airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. But the frontal
airbags would not help you in many types of collisions,
including rollovers, rear impacts, and many side impacts,
primarily because an occupant’s motion is not toward the
airbag. Side impact airbags 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 airbags.
Airbags 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 airbags, and only in
moderate to severe side collisions for vehicles with a
driver’s and right front passenger’s side impact airbag.
What Will You See After an Airbag
Inates?
After the airbag inates, it quickly deates, so quickly
that some people may not even realize the airbag
inated. Some components of the airbag module will be
hot for a short time. These components include the
steering wheel hub for the driver’s frontal airbag and the
instrument panel for the right front passenger’s frontal
airbag. For vehicles with side impact airbags, the side of
the seatback closest to the driver’s and/or right front
passenger’s door will be hot. 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 deated airbags.
Airbag ination does not prevent the driver from seeing
or being able to steer the vehicle, nor does it stop
people from leaving the vehicle.
1-58

{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
airbag system. If this ever happens, have the
vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the frontal airbag. SeeAirbag Readiness
Light on page 3-31for more on this, including
important safety information.
Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or other
aftermarket equipment if your vehicle has the passenger
sensing system. SeeAdding Equipment to Your
Airbag-Equipped Vehicle on page 1-64for more
information about modications that can affect how the
system operates.
{CAUTION:
Stowing of articles under the passenger’s seat
or between the passenger’s seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.
