When either the passenger sensing system and/or
the AIR BAG
OFF switch has turned off the
right front passenger’s frontal air bag, the
off
indicator in the passenger air bag status indicator
on the rearview mirror will light and stay lit
when
y-” 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.
If the air bag readiness light
in the instrument
panel cluster ever comes
on when you have
turned
off the air bag, it means that something
may be wrong with the air bag system. The
right front passenger’s air bag could inflate
even though the switch
is off. If this ever
happens, have the vehicle serviced promptly.
Until
you have the vehicle serviced, don’t let
anyone whom the national government has identified as a member of a passenger air bag
risk group sit in the right front passenger’s
position (for example, don’t secure a
rear-facing child restraint
in your vehicle). See
”Air Bag
Off Switch” in the Index. 4. Buckle the belt. Make sure the release button is
positioned
so you would be able to unbuckle the
safety belt quickly
if you ever had to.
1-53

if your vehicle has the passenger sensing system and
you’re using a rear-facing child restraint in this seat,
check to be sure the right front passenger’s frontal air
bag is
off before you begin to drive. If the air bag
has been turned
off, the off indicator wiii iight and stay
lit in the rearview mirror.
If the on indicator is lit, the passenger’s frontal air bag
has not been turned
off by the passenger sensing
system. If this ever happens, turn the vehicle
off,
unbuckle the safety belt and perform the steps to install
the rear-facing restraint again. After restarting the
vehicle,
if the air bag still doesn’t turn off, install the
infant restraint in a rear seat position of the vehicle or
check to make sure the AIR
BAG OFF switch has been
turned to
off. See Air Bag Off Switch on page 1-64
and Passenger Sensing System on page 1-68.
If the air bag ON indicator comes on when you
have a rear-facing child restraint installed in
the right front passenger’s seat, it means that
the passenger sensing system has not turned
off the passenger’s frontal air bag. 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. Don’t use a
rear-facing child restraint
in the right front
passenger’s seat unless the air bag
is off.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will remove freely again and be ready to work for an
adult or larger child passenger.

The words ON and
OFF or the symbol for on and off,
will be visible on the rearview mirror during the system

the symbol for
off will be visible. See Passenger Air

Outside Power Mirrors
If your vehicle is equipped
with outside power mirrors,
the controls are located
on the driver’s door
armrest.
Move the selector switch located above the control pad
to the left or right to choose the mirror you want to
adjust, then press the dots located on the four-way
control pad to adjust the mirror.
The mirrors include ground illumination lamps (puddle
lamps) in the base of the mirror. For more information on
these lamps, see
Puddle Lamps under Exterior Lamps
on page 3-1
1.
The mirrors also include a memory function which works
in conjunction with the memory seats. See “Memory
Seats” in the Index for more information.
Outside Power Foldaway Mirrors
If your vehicle is equipped with outside power foldaway
mirrors the mirrors can be folded in toward the body
of the vehicle.
To fold
in the mirrors, move the upper selector switch,
located above the mirror control, to the middle position.
Press the right side of the mirror control to fold the
mirrors toward the body
of the vehicle. The mirror glass
on one or both sides of the vehicle may automatically
adjust before the mirror folds inward. When the
mirror glass or mirror starts moving, you can release the
mirror control.
To return the mirrors and the mirror glass to their
normal position press the left side of the mirror control.
If the mirrors are manually folded, use the power
mirror control to return it to it’s original position.
Outside Automatic Dimming Mirror
The driver’s outside mirror will adjust for the glare of any
headlamps behind you. This feature is controlled by
the on and
off settings on the electrochromic mirror. See
“Electrochromic Mirror Operation” under
Automatic
Dimming Rearview Mirror with Onstat? Compass and
Temperature Display on page
2-28.

Outside Curb View Assist Mirrors
If your vehicle has the optional memory package
you may have this feature.
The vehicle’s mirrors are 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.
You may be able to enabled/disable this feature through
the Driver Information Center. See
Driver Information
Center (DIC) on page
3-43.
Outside Convex Mirror
Your passenger’s side mirror is convex. A convex
mirror’s surface is curved
so you can see more from the
driver’s seat.
A convex mirror can make things (like other
vehicles)
look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Heated Mirrors
The outside rearview mirrors with this option have a
defrost mode.
To turn on the defrost feature, press the rear window
defogger button. See “Rear Window Defogger”
under
Dual Automatic Climate Control System on
page 3-18 for further information.
