A child in a rear-facing child restraint can be
seriously injured or killed if the right front passenger’s air bag inflates. This
is because
the back of the rear facing child restraint
would be very close
to the inflating air bag.
Be sure the air bag is
off before using a
rear-facing child restraint
in the right front seat
position.
Even though the passenger sensing system is
designed to turn
off the passenger’s frontal air
bag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an air bag will not deploy under some unusual circumstance, even
though
it is turned off. General Motors
therefore recommends that rear-facing child restraints be secured in the rear seat whenever
possible, even
if the air bag is off.
You’ll be using the lap-shoulder belt. See Top Strap on
page
1-57 if the child restraint has one. Be sure to
follow the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Because your vehicle has a right front passenger
air bag, always move the seat as far back as it will
go before securing a child restraint,
if you need
to secure a forward-facing child restraint in the right
front seat position. See
Power Seats on page 1-3.
If your vehicle has the passenger sensing
system and you are using a rear-facing child
restraint in this seat, make sure the frontal air bag
is
off. See Passenger Sensing System on
page
1-8 1.
When the passenger sensing system has turned off
the right front passenger’s frontal air bag, the off
indicator on the inside rearview mirror will light and
stay lit when you turn the ignition to RUN or
START.
2. Put the restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show
you how.

Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a passenger
sensing system. The indicator will be visible when you
turn your ignition key
to START or RUN. The words ON
and OFF or the symbol for on and off, will be visible on
the rearview mirror during the system check. When the
system check
is complete, either the word ON or the word
OFF, or the symbol for on or the symbol for off will be
visible. See Passenger
Air Bag Status Indicator on
page 3-32. If your rearview mirror doesn’t have either of
the indicators pictured, then your vehicle doesn’t have the
passenger sensing system.
L
Passenger Air Bag Status Indicator - United States Passenger
Air Bag
Status Indicator
- Canada
The passenger sensing system will turn off the right
front passenger’s frontal air bag under certain
conditions. The driver’s air bag and the side air bags
are not part
of the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence of
a properly-seated occupant and determine
if the
passenger’s frontal air bag should be enabled
(may inflate) or not.
Accident statistics show that children are safer
if they
are restrained in the rear rather than the front seat.
General Motors, therefore, recommends that child
restraints be secured in a rear seat including an infant
riding in a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding in a
booster seat. Never put a child in rear facing child

Mirrors
Automatic Dimming Rearview Mirror
with Onstar@, Compass
and
Temperature Display
Your vehicle may have this feature. When on, an
electrochromic mirror automatically dims to the proper
level to minimize glare from lights behind you after dark.
The mirror also includes a duel display in the upper
right corner of the mirror face. The compass reading and
the outside temperature will both appear in the display
at the same time.
Temperature and Compass Display
Press the on/off button, located to the far left, briefly to
turn the comp/temp display on or
off.
If the display reads CAL, you will need to calibrate the
compass. For more information on calibration, see
below.
To adjust between Fahrenheit and Celsius do the
following:
1.
2. Press and hold the
on/off button for approximately
four seconds until either a flashing OF, or "C
appears.
Press the button again to change the display to the
desired unit
of measurement. After approximately
four seconds of inactivity, the new unit will be locked
in and the compass/temperature display will
return.
6 (On/Off): This is the on/off button.

Outside Heated Mirrors
You vehicle may have this feature.
When you press this
button, a defogger warms
the heated driver’s and passenger’s outside rearview mirrors
to help
clear them of ice, snow and
condensation.
Your vehicle’s rear window defogger will also operate
when you press this button. See “Rear Window
Defogger” under Electronic Climate Control System on
page
3-79 for more information.
Outside Automatic Dimming Mirror
with Curb View Assist
The driver’s outside mirror will adjust for the glare of the
headlamps behind you. See Automatic Dimming
Rearview Mirror with OnStap, Compass and
Temperature Display on page
2-31 earlier in this
section.
Your vehicle’s mirrors will also be capable of performing
the curb view assist mirror function. This feature will
cause the passenger’s and/or driver’s mirror
to tilt to a
preselected position when the vehicle is in
REVERSE
(R). This feature may be useful in allowing
you
to view the curb when you are parallel parking.
When the vehicle is shifted out of REVERSE
(R) and a
short delay has occurred, the passenger’s and/or
driver’s mirror will return
to its original position.
To change the preselected tilt position, adjust the
mirrors
to the desired position while the vehicle is in
REVERSE
(R). When the vehicle is shifted out of
REVERSE
(R), this new position is saved in memory as
the tilt position.
This feature can be enabled/disabled through the Driver
lnformation Center. See Driver lnformation Center
@IC) on page
3-43 for more information.

the rear-facing child restraint would be very close to the inflating air bag. Don’t use a
