the liftgate, or trunk/hatch open:
.Close all of the windows.
.Fully open the air outlets on
or under the instrument
panel.(Continued)

system to a setting that
brings in only outside air and
set the fan speed to the
highest setting. See “Climate
Control Systems” in the

you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.

Automatic Dimming
Rearview Mirror
The vehicle has an automatic
dimming inside rearview mirror.
Automatic dimming reduces the
glare from the headlamps of the
vehicle behind you.

control buttons located at the
bottom of the mirror. See your
dealer for more information about
OnStar and how to subscribe to it.
See OnStar Overview on page 14‑1.
Cleaning the Mirror
Do not spray glass cleaner directly
on the mirror. Use a soft towel
dampened with water.
Windows
{WARNING
Leaving children, helpless adults,
or pets in a vehicle with the
windows closed is dangerous.
They can be overcome by the
extreme heat and suffer
permanent injuries or even death
from heat stroke. Never leave a
child, a helpless adult, or a pet
alone in a vehicle, especially with
the windows closed in warm or
hot weather.
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when a window is
partially open. To reduce the sound,
open another window or the sunroof
(if equipped).

3-2 Seats and Restraints
Head Restraints
The vehicle's front and rear seats
have adjustable head restraints in
the outboard seating positions.
{WARNING
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.
Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the
chance of a neck injury in a crash.

press the release button located on
the side of the head restraint and
pull up or push the head restraint
down and release the button.
Pull and push on the head restraint

3-6 Seats and Restraints
Reclining Seatbacks
{WARNING
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled
up, the safety belts cannot do
their job when reclined like this.
The shoulder belt cannot do its
job because it will not be against
your body. Instead, it will be in
front of you. In a crash, you could
go into it, receiving neck or other
injuries.
The lap belt cannot do its job
either. In a crash, the belt could
go up over your abdomen. The
belt forces would be there, not at
your pelvic bones. This could
cause serious internal injuries.(Continued)
WARNING (Continued)
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
safety belt properly.
Do not have a seatback reclined if
the vehicle is moving.
Manual Reclining Seatbacks
{WARNING
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.

change or pain to the skin, the
seat heater may cause burns
even at low temperatures. To
reduce the risk of burns, people
with such a condition should use
care when using the seat heater,
especially for long periods of
time. Do not place anything on
the seat that insulates against
heat, such as a blanket, cushion,
cover, or similar item. This may
cause the seat heater to
overheat. An overheated seat
heater may cause a burn or may
damage the seat.

3-10 Seats and Restraints
Raising the Seatback
{WARNING
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.
{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.To raise a seatback:
1. Lift the seatback up and push it
rearward to lock it in place.
Make sure the safety belt is in
the retainer clip (if equipped)
and is not twisted or caught in
the seatback.
A tab near the seatback lever
retracts when the seatback is
locked in place.
2. Push and pull the top of the seatback to be sure it is locked
into position.
3. Repeat the steps to raise the other seatback, if necessary.
When the seat is not in use, it
should be kept in the upright, locked
position.
Safety Belts
This section of the manual
describes how to use safety belts
properly. It also describes some
things not to do with safety belts.
{WARNING
Do not let anyone ride where a
safety belt cannot be worn
properly. In a crash, if you or your
passenger(s) are not wearing
safety belts, injuries can be much
worse than if you are wearing
safety belts. You can be seriously
injured or killed by hitting things
inside the vehicle harder or by
being ejected from the vehicle. In
addition, anyone who is not
buckled up can strike other
passengers in the vehicle. (Continued)
