10Airbag sensor assembly
The SRS front airbag system consists mainly of the above
components, and their locations are shown in the illustration.
The airbag sensor assembly consists of a safing sensor and
airbag sensor.
The airbag sensors constantly monitor the forward
deceleration of the vehicle. If an impact results in a forward
deceleration beyond the designed threshold level, the system
triggers the airbag inflators. At this time a chemical reaction in
the inflators very quickly fills the airbags with non− toxic gas to
help restrain the forward motion of the occupants. The front
airbags then quickly deflate, so that there is no obstruction of
the driver’s vision should it be necessary to continue driving. When the airbags inflate, they produce a loud noise and
release some smoke and residue along with non
−toxic gas.
This does not indicate a fire. This smoke may remain inside the
vehicle for some time, and may cause some minor irritation to
the eyes, skin or breathing. Be sure to wash off any residue as
soon as possible to prevent any potential skin irritation with
soap and water. If you safely exit from the vehicle, you should
do so immediately.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, primarily to the
head and chest, it may also cause other, less severe injuries
to the face, chest, arms and hands. These are usually in the
nature of minor burns or abrasions and swelling, but the force
of a deploying airbag can cause more serious injuries,
especially if an occupant’s hands, arms, chest or head are in
close proximity to the airbag module at the time of deployment.
This is why it is important for the occupant to: avoid placing any
object or part of the body between the occupant and the airbag
module; sit straight and well back into the seat; wear the
available seat belt properly; and sit as far as possible from the
airbag module, while still maintaining control of the vehicle.
Parts of the airbag module (steering wheel hub, airbag cover
and inflator) may be hot for several minutes after deployment,
so do not touch! The airbags inflate only once. The windshield
may be damaged by absorbing some of the force of the
inflating airbag.

SRS SIDE AIRBAGS AND CURTAINSHIELD AIRBAGS
The SRS (Supplemental Restraint System) side airbags
and curtain shield airbags are designed to provide further
protection for the driver, front passenger and rear
outboard passengers in addition to the primary safety
protection provided by the seat belts.
In response to a severe side impact, the SRS side airbags and
curtain shield airbags work with the seat belts to help reduce
injury by inflating. The SRS side airbags help reduce injuries
mainly to the driver’s or front passenger’s torso and the SRS
curtain shield airbags help reduce injuries mainly to the
driver’s, front passenger’s or rear outboard passenger’s head. The SRS side airbag on the passenger seat will not activate if
there is no passenger sitting in the front passenger seat.
However,
the side airbag on the passenger seat may deploy if
luggage is put in the seat, or the seat belt is buckled up
regardless of the presence of the occupant in the seat. (As for
the front passenger occupan t classification system, see “Front
passenger occupant classification system” on page 168.)
Roll sensing function:
In response to a vehicle rollover, the curtain shield airbags on
both sides work with the seat belts to help reduce injury by
inflating. The curtain sh ield airbags help reduce injuries mainly
to the driver’s, front passenger’s or second passenger’s head
and help prevent them from being thrown out of the vehicle.
(This function can be turned off if inflation is not desired. See
“Roll sensing of curtain shield airbags off switch” on page 174.)
The SRS curtain shield airbag on the passenger side are
activated even with no passenger in the front seat or second
outboard seat.
The SRS curtain shield airbags may activate even when the
side airbags are not activated.
Always wear your seat belt properly.

CAUTION
SRS side airbags and curtain shield airbags inflate with
considerable force. To reduce the possibility of death
or serious injury when they inflate, the driver, front
passenger and rear outboard passengers must:
Wear their seat belts properly.
 Remain properly seated with their backs upright and
against the seats at all times.
Do not allow anyone to lean against the door when
the vehicle is in use, since the side airbag and curtain
shield airbag could inflate with considerable speed
and force. Otherwise, he/she may be killed or
seriously injured. Special care should be taken
especially when you have a small child in the vehicle.
 Sit up straight and well back in the seat, distributing
your weight evenly in the seat. Do not apply
excessive weight to the outer side of the seats with a
side airbag and to the front pillar, rear pillar and roof
side rail with a curtain shield airbag.
 Improper sitting and wearing of the seat belts may
not retain you inside the vehicle.

Make sure the “RSCA OFF” indicator light is off. The
curtain shield airbags will not inflate in a vehicle
rollover if this indicator light is on and you may be
killed or seriously injured. For details, see “Roll
sensing of curtain shield airbags off switch” on page
174. Do not allow anyone to get his/her head closer to the
area where the side airbag and curtain shield airbag
inflate, since these airbags could inflate with
considerable speed and force. Otherwise, he/she
may be killed or seriously injured. Special care
should be taken especially when you have a small
child in the vehicle.
 Do not allow anyone to kneel on the passenger seat,
facing the passenger’s side door, since the side
airbag and curtain shield airbag could inflate with
considerable speed and force. Otherwise, he/she
may be killed or seriously injured. Special care
should be taken especially when you have a small
child in the vehicle.

OCCUPANT RESTRAINT SYSTEMS

Do not allow anyone to get his/her head or hands out
of windows, since the curtain shield airbags could
inflate with considerable speed and force.
Otherwise, he/she may be killed or seriously injured.
Special care should be taken especially when you
have a small child in the vehicle. Do not attach a cupholder or any other device or
object on or around the door. When the side airbag
and curtain shield airbag inflate, the cupholder or any
other device or object will be thrown with great force,
or the side airbag and curtain shield airbag may not
activate correctly, resulting in death or serious injury.
Likewise, the driver and front passenger should not
hold objects in their arms or on their knees.

STEERING WHEEL AND MIRRORS
206
INSIDE REAR VIEW MIRROR
Adjust the mirror so that you can just see the rear of your
vehicle in the mirror.
Pushing the “MIRROR” switch changes the mode
between AUTO and DAY.
The indicator comes on when the automatic function mode is
selected.
DAY mode: The mirror surface is normal.
AUTO 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 ignition key is inserted and turned on, the inside rear
view mirror always turns on in the automatic function 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.
Doing so may cause the
driver to mishandle the vehicle
and an accident may occur resulting in death or serious
injuries.
To ensure correct functioning of antiglare mirror sensors
located on both sides of the mirror, do not touch or cover
the sensors with your finger or a piece of cloth, etc.
