COMFORT ADJUSTMENT
129 Adjust the mirror so that you can just see the rear of
your vehicle in the mirror.
Pushing the switch changes the mode between
ºAUTOº and ºDAYº.
The indicator comes on when the ºAUTOº mode is
selected.
ºDAYº mode: The mirror surface is normal.
ºAUTOº mode: If the mirror detects light from the
headlights of the vehicle behind you, the mirror
surface darkens slightly to reduce the reflected
light.
When the inside rear view mirror surface changes, the
outside rear view mirror surfaces will also become
darker.
When the ignition key is inserted and turned on, the
inside rear view mirror always turns on in the ºAUTOº
mode.When the outside air temperature is low, it may take a
little longer for the mirror to darken in response to the
detection of headlights.
CAUTION
Do not adjust the mirror while the vehicle is moving. It
may cause the driver to mishandle the vehicle and an
accident may occur resulting in personal injuries.

Driver and front passenger airbags, and seat belt
pretensioners
Driver and front passenger airbags:In response to a severe frontal impact, the driver and
front passenger airbags work together with the seat
belts to help preventing or reduce injury by inflating,
in order to decrease the likelihood of the driver's or
front passenger's heads or chests from directly
hitting the steering wheel or dashboard.
Seat belt pretensioners:
In response to a severe frontal impact, the seat belts
are quickly drawn back in by the retractors so that
the belts snugly restrain the driver and front
passenger.
The front passenger airbag is activated even with no
passenger in the front seat.
The seat belt pretensioners are activated even with no
passenger in the front seat.
Be sure to wear your seat belt.

COMFORT ADJUSTMENT

Side airbags
Side airbags:In response to a severe side impact, the side airbag
for the driver or front passenger works together with
the seat belt to help preventing or reducing injury by
inflating, in order to decrease the impact mainly on
the driver or front passenger's chest.
The side airbag on the passenger seat is activated even
with no passenger in the front seat.
Be sure to wear your seat belt.

COMFORT ADJUSTMENT
146The driver and front passenger airbags and seat belt
pretensioners are designed to activate in response
to a severe frontal impact within the shaded area
between the arrows in the illustration.
There may be the case that the driver and passenger
airbags and seat belt pretensioners will not activate with
such an impact in which the occupant wearing the seat
belt correctly would not get serious injury.
The driver and front passenger airbags and seat belt
pretensioners will work if the severity of the impact is
above the designed threshold level, comparable to an
approximate 25 km/h (15 mph) collision in the U.S.A.
and 30 km (18 mph) collision in Canada when impacting
straight into a fixed barrier that does not move or deform.
If the severity of the impact is below the above threshold
level, the driver and front passenger airbags and seat
belt pretensioners may not work.However, this threshold velocity will be considerably
higher if the vehicle strikes an object, such as a parked
vehicle or sign pole, which can move or deform on
impact, or if it is involved in an underride collision (e.g.
a collision in which the nose of the vehicle ºunderridesº,
or goes under, the bed of a truck, etc.).
It is possible with collision severity at the marginal level
of driver and passenger airbag sensor detection and
activation that only one of your vehicle's driver and front
passenger airbags and seat belt pretensioners will work.
For the safety of all occupants, be sure to always wear
seat belts.
