es) sit in the REAR seat properly restrained at
all times in a child restraint device or in a seat-
belt, whichever is appropriate for the child’s
age, height and weight.
Secure ALL types of child restraint devices (in-
cluding forward facing child seats) in the REAR
seats at all times.
According to accident statistics, children are
safer when properly restrained in the rear seat-
ing positions than in the front seating posi-
tions.
For instructions and precautions concerning
the child restraint system, see the “Child re-
straint systems” section in this chapter. "
NEVER INSTALL A REARWARD FACING
CHILD SEAT IN THE FRONT SEAT. DOING SO RISKS SERIOUS INJURY OR DEATH TO THE
CHILD BY PLACING THE CHILD’S HEAD TOO
CLOSE TO THE SRS AIRBAG." Never allow a child to stand up, or to kneel on
the front passenger’s seat, or never hold a child
on your lap or in your arms. The SRS airbag de-
ploys with considerable force and can injure or
even kill the child.
" When the SRS airbag deploys, some smoke
will be released. This smoke could cause
breathing problems for people with a history of
asthma or other breathing trouble. If you or
your passengers have breathing problems after
SRS airbag deploys, get fresh air promptly." A deploying SRS airbag releases hot gas. Oc-
cupants could get burnt if they come into direct
contact with the hot gas.
NOTE
When you sell your vehicle, we urge you to explain
to the buyer that it is equipped with SRS airbags
by alerting him to the applicable section in this
owner’s manual.

SRS frontal airbag
The driver’s SRS frontal airbag is stowed in the center
portion of the steering wheel. The passenger’s SRS
frontal airbag is stowed near the top of the dashboard
under an “SRS AIRBAG” mark.
In a moderate to severe frontal collision, the driver’s
and front passenger’s SRS frontal airbags deploy and
supplement the seatbelts by reducing the impact on
the driver’s and front passenger’s head and chest.

The SRS airbag deploys with considerable
speed and force. Occupants who are out of
proper position when the SRS airbag deploys
could suffer very serious injuries. Because the
SRS airbag needs enough space for deploy-
ment, the driver should always sit upright and
well back in the seat as far from the steering
wheel as practical while still maintaining full ve-
hicle control and the front passenger should
move the seat as far back as possible and sit
upright and well back in the seat.
It is also important to wear your seatbelt to help

avoid injuries that can result when the SRS air-
bag contacts an occupant not in proper posi-
tion such as one thrown toward the front of the
car during pre-accident braking.
Do not put any objects over the steering wheel
pad and dashboard. If the SRS frontal airbag
deploys, those objects could interfere with its
proper operation and could be propelled inside
the vehicle and cause injury.
Do not attach accessories to the windshield, or
fit an extra-wide mirror over the rear view mir-
ror. If the SRS airbag deploys, those objects
could become projectiles that could seriously
injure vehicle occupants.

Seat, seatbelt and SRS airbags
The SRS airbag can function only when the ignition
switch is in the “ON” position.
If the front sub sensors inside the both front fenders
and the impact sensors in the airbag control module
detect a certain predetermined amount of force during
a frontal collision, the control module sends signals to
the frontal airbag modules instructing them to inflate
the SRS frontal airbags. Then both airbag modules
produce gas, which instantly inflates driver’s and pas-
senger’s SRS frontal airbags. After the deployment,
the SRS airbags immediately start to deflate so that
the driver’s vision is not obstructed. The time required
from detecting impact to the deflation of the SRS air-
bag after deployment is shorter than the blink of an eye.
The front passenger’s SRS frontal airbag deploys to-
gether with driver’s SRS frontal airbag even when no
one occupies the front passenger’s seat.
Although it is highly unlikely that the SRS airbag would
activate in a non-accident situation, should it occur,
the SRS airbag will deflate quickly, not obscuring vi-
sion and will not interfere with the driver’s ability to
maintain control of the vehicle.
When the SRS airbag deploys, a sudden, fairly loud
inflation noise will be heard and some smoke will be
released. These occurrences are normal result of the
deployment. This smoke does not indicate a fire in the vehicle.
Do not touch the SRS airbag system compo-
nents around the steering wheel and dash-
board with bare hands right after deployment.
Doing so can cause burns because the compo-
nents can be very hot as a result of deployment.
The SRS frontal airbag is designed to deploy in the
event of an accident involving a moderate to severe
frontal collision. It is basically not designed to deploy
in lesser frontal impacts because the necessary pro-
tection can be achieved by the seatbelt alone. Also, it
is basically not designed to deploy in side or rear im-
pacts or in roll-over accidents because deployment of
the SRS frontal airbag would not help the occupant in
those situations. The SRS airbag is designed to func-
tion on a one-time-only basis.
SRS airbag deployment depends on the level of force
experienced in the passenger compartment during a
collision. That level differs from one type of collision to
another, and it may have no bearing on the visible

damage done to the vehicle itself. "When will the SRS frontal airbag most likely de-
ploy?
A head-on collision against a thick concrete wall at a
vehicle speed of 12 to 19 mph (20 to 30 km/h) or high-
er activates the SRS frontal airbag. The SRS frontal
airbag will also be activated when the vehicle is ex-
posed to a frontal impact similar in fashion and magni-
tude to the above-mentioned collision. "
At what other times might the SRS frontal air-
bag deploy?
The SRS frontal airbag may be activated when the ve-
hicle sustains a hard impact in the undercarriage area
from the road surface (such as when the vehicle
