Resetting the Power Folding
Mirrors
Reset the power folding mirrors if:
.The mirrors are accidentally
obstructed while folding.
.They are accidentally manually
folded/unfolded.
.The mirrors will not stay in the
unfolded position.
.The mirrors vibrate at normal
driving speeds.
Fold and unfold the mirrors one time
using the mirror controls to reset
them to their normal position.
A popping noise may be heard
during the resetting of the power
folding mirrors. This sound is normal
after a manual folding operation.
Manual Folding
Fold the mirrors inward to prevent
damage when going through an
automatic car wash. To fold, pull the
mirror toward the vehicle. Push the
mirror outward, to return to its
original position.

Automatic Dimming
Mirror
If the vehicle has the automatic
dimming mirror, the driver outside
mirror automatically adjusts for the
glare of the headlamps from behind.
This feature is controlled by the
on and off setting on the inside
rearview mirror. See Automatic
Dimming Rearview Mirror on
page 2‑22.
Park Tilt Mirrors
If the vehicle has the memory
package, the exterior mirrors tilt to
a preselected position when the
vehicle is in R (Reverse). This
feature lets the driver view the curb
when parallel parking. The mirrors
return to the original position
when the vehicle is shifted out of
R (Reverse), or the ignition is turned
off or to OFF/LOCK.
This feature can be programed
through the Driver Information
Center (DIC). See Vehicle
Personalization (With DIC Buttons)
on page 5‑44 for more information.

3-10 Seats and Restraints
Rear Seats
The rear seatbacks can be folded to
provide more cargo space and
access to the midgate. See
Midgate
®on page 2‑8.
To fold the seatback:
1. Push the rear seat headrests all the way down.
2. Pull the loop in the crease wherethe seatback and seat cushion
meet to release the seat cushion. Tilt the seat cushion
forward toward the front of the
vehicle.
Notice: Folding a rear seat with
the safety belts still fastened may
cause damage to the seat or the
safety belts. Always unbuckle the
safety belts and return them to
their normal stowed position
before folding a rear seat.3. Fold the seatback forward until it is flat. If necessary, move the
front seats forward slightly to
allow the seatback to fold
completely. 4. Repeat the procedure for the
other seatback, if desired.
To return the seats to the normal
position, lift the seatback up and
fold the seat cushion down.
{WARNING
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.

Black plate (15,1)Chevrolet Avalanche Owner Manual - 2013 - CRC - 8/27/12
Seats and Restraints 3-15
To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger positions.Adjust the height so the shoulder
portion of the belt is on the shoulder
and not falling off of it. The belt
should be close to, but not
contacting, the neck. Improper
shoulder belt height adjustment
could reduce the effectiveness of
the safety belt in a crash. See
How
to Wear Safety Belts Properly on
page 3‑12.Squeeze the buttons (A) on the
sides of the height adjuster and
move the height adjuster to the
desired position. The adjuster can be moved up just
by pushing up on the shoulder belt
guide.
After the adjuster is set to the
desired position, try to move it down
without squeezing the buttons to
make sure it has locked into
position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety belt
pretensioners cannot be seen, they
are part of the safety belt assembly.
They can help tighten the safety
belts during the early stages of a
moderate to severe frontal, near
frontal, or rear crash if the threshold
conditions for pretensioner
activation are met. And, if the
vehicle has side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or a rollover event.

Black plate (26,1)Chevrolet Avalanche Owner Manual - 2013 - CRC - 8/27/12
3-26 Seats and Restraints
Frontal airbag modules are located
inside the steering wheel and
instrument panel. For vehicles with
seat‐mounted side impact airbags,
there are airbags modules in the
side of the front seatbacks closest
to the door. For vehicles with
roof-rail airbags, there are airbag
modules in the ceiling of the vehicle,
near the side windows that have
occupant seating positions.
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.
Airbags supplement the protection
provided by safety belts. Frontal
airbags distribute the force of the
impact more evenly over the
occupant's upper body, stopping the
occupant more gradually. Seat‐mounted side impact and roof-rail
airbags distribute the force of the
impact more evenly over the
occupant's upper body.
Rollover capable roof-rail airbags
are designed to help contain the
head and chest of occupants in the
outboard seating positions in the
first and second rows. The rollover
capable roof-rail airbags are
designed to help reduce the risk of
full or partial ejection in rollover
events, although no system can
prevent all such ejections.
But airbags would not help in many
types of collisions, primarily
because the occupant's motion is
not toward those airbags. See
When
Should an Airbag Inflate? on
page 3‑24 for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See after
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at least
partially inflated for some time after
they deploy. Some components of
the airbag module may be hot for
several minutes. For location of the
airbag modules, see What Makes
an Airbag Inflate? on page 3‑25.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not
prevent the driver from seeing out of
the windshield or being able to steer
the vehicle, nor does it prevent
people from leaving the vehicle.
