child closer to the belt buckle to help
provide a good shoulder belt fit. Care must
be taken to securely place the lap belt as
low as possible on the hips and not on thechild’s waist. If the shoulder portion of the
belt cannot be properly positioned, a child
restraint system should be used. Never
place the shoulder belt under the child ’s
arm or behind the child ’s back.
! Expectant mothers
Expectant mothers also need to use the
seatbelts. They should consult their doctor
for specific recommendations. The lap belt
should be worn securely and as low as
possible over the hips, not over the waist. &
Emergency Locking Retrac-
tor (ELR)
The driver ’s seatbelt has an Emergency
Locking Retractor (ELR).
The emergency locking retractor allows
normal body movement but the retractor
locks automatically during a sudden stop,
impact or if you pull the belt very quickly
out of the retractor. & Automatic/Emergency Lock-
ing Retractor (A/ELR)
Each passenger ’s seatbelt has an Auto-
matic/Emergency Locking Retractor (A/
ELR). The Automatic/Emergency Locking
Retractor normally functions as an Emer-
gency Locking Retractor (ELR). The A/
ELR has an additional locking mode“ Automatic Locking Retractor (ALR)
mode ”intended to secure a child restraint
system. When the seatbelt is once drawn
out completely and is then retracted even
slightly, the retractor locks the seatbelt in
that position and the seatbelt cannot be
extended. As the belt is rewinding, clicks
will be heard which indicate the retractor
functions as an ALR. When the seatbelt is
retracted fully, the ALR mode is released.
When securing a child restraint system on
the rear seats by the use of the seatbelt,
the seatbelt must be changed over to the Automatic Locking Retractor (ALR) mode.
When the child restraint system is re-
moved, make sure that the seatbelt
retracts fully and the retractor returned to
the Emergency Locking Retractor (ELR) mode.
For instructions on how to convert the
retractor to the ALR mode and restore it to
the ELR mode, refer to
“Installing child
restraint systems with A/ELR seatbelt ”
F 1-24.

& Fastening the seatbelt
WARNING
. Never use a belt that is twisted or
reversed. In an accident, this can
increase the risk or severity of
injury.
. Keep the lap belt as low as
possible on your hips. In a colli-
sion, this spreads the force of the
lap belt over stronger hip bones
instead of across the weakerabdomen.

A: Front passenger’s seat
You should not install a child restraint
system (including a booster seat) due to
the hazard to children posed by thepassenger ’s airbag.
B: Rear seat, window-side seatingpositions
Recommended positions for all types of
child restraint systems.
In these positions, Automatic/Emergency
Locking Retractor (A/ELR) seatbelts and
lower anchorages (bars) are provided for
installing a child restraint system.
Some types of child restraints might not be
able to be secured firmly due to projection
of the seat cushion.
In this seating position, you should use
only a child restraint system that has a
bottom base that fits snugly against the
contours of the seat cushion and can be
securely retained using the seatbelt.
C: Rear seat, center seating position
Installing a child restraint system is not
recommended, although the A/ELR seat-
belt and an upper anchorage (tether
anchorage) (except in Latin American
models) are provided in this position.
Some types of child restraints might not be
able to be secured firmly due to projection
of the seat cushion. In this seating position, you should use
only a child restraint system that has a
bottom base that fits snugly against the
contours of the seat cushion and can be
securely retained using the seatbelt.
If it is unavoidable to install a child
restraint system in the rear seat
’s center
seating position, lower the center head
restraint to the lowest position and install
the child restraint system by correctly
passing the rear center seatbelt through
the belt guide.
WARNING
Put children aged 12 and under in
the rear seat properly restrained at
all times. The SRS airbag deploys
with considerable speed and force
and can injure or even kill children,
especially if they are 12 years of age
and under and are not restrained or
improperly restrained. Because chil-
dren are lighter and weaker than
adults, their risk of being injured
from deployment is greater. For that reason, be sure to secure
ALL types of child restraint devices
(including forward facing child
seats) in the REAR seats at all times.
You should choose a restraint de-
vice which is appropriate for thechild
’s age, height and weight. Ac-
cording to accident statistics, chil-
dren are safer when properly re-
strained in the rear seating posi-
tions than in the front seating posi-tions.

SINCE YOUR VEHICLE IS
EQUIPPED WITH A PASSENGER ’S

8. If the child restraint system requires a
top tether, latch the hook onto the top
tether anchorage and tighten the top
tether. For additional instructions, refer to“ Top tether anchorages ”F 1-31.
9. To remove the child restraint system,
press the release button on the seatbelt
buckle and allow the belt to retract
completely. The belt will return to the
ELR mode. NOTE
When the child restraint system is no
longer in use, remove it and restore the
ELR function of the retractor. That
function is restored by allowing the
seatbelt to retract fully. & Installing a booster seat
WARNING
. Child restraint systems and seat-
belts can become hot in a vehicle
that has been closed up in sunny
weather; they could burn a small
child. Check the child restraint
system before you place a child
in it.
. Do not leave an unsecured child
restraint system in your vehicle.
Unsecured child restraint sys-
tems can be thrown around in-
side of the vehicle in a sudden
stop, turn or accident; they can
strike and injure vehicle occu-
pants as well as result in serious

*SRS airbag (Supplemental
Restraint System airbag)
*SRS: This stands for supplemental re-
straint system. This name is used be-
cause the airbag system supplements thevehicle’s seatbelts.
Your vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seatbelt by the front
passenger when any of the SRS frontal,
side and curtain airbags deploys. & Models with SRS airbags and
lap/shoulder restraints for
driver, front passenger, and
window-side rear passengers
Your vehicle is equipped with a supple-
mental restraint system in addition to a
lap/shoulder belt at each front seating
position and each rear window-side seat-
ing positions. The supplemental restraint
system (SRS) consists of six airbags.
The configurations are as follows. . Driver ’s and front passenger ’s frontal
airbags . Driver ’s and front passenger ’s side
airbags. Curtain airbags (for driver, front pas-
senger, and window-side rear passen- gers)
These SRS airbags are designed only
as a supplement to the primary protec-
tion provided by the seatbelt.
The system also controls front seatbelt
pretensioners. For operation instructions
and precautions concerning the seatbelt
pretensioner, refer to
“Front seatbelt pre-
tensioners ”F 1-19.
WARNING
. To obtain maximum protection in
the event of an accident, the
driver and all passengers in the
vehicle should always wear seat-
belts when the vehicle is moving.
The SRS airbag is designed only
as a supplement to the primary
protection provided by the seat-
belt. It does not do away with the
need to fasten seatbelts. In com-
bination with the seatbelts, it
offers the best combined protec-
tion in case of a serious accident.
Not wearing a seatbelt increases
the chance of severe injury or
death in a crash even when the
vehicle has the SRS airbag.
For instructions and precautions
concerning the seatbelt system, refer to
“Seatbelts ”F 1-11.
. Do not sit or lean unnecessarily
close to the SRS airbag. Because
the SRS airbag deploys with
considerable speed –faster than
the blink of an eye –and force to
protect in high speed collisions,
the force of an airbag can injure
an occupant whose body is too
close to SRS airbag.
It is also important to wear your
seatbelt to help avoid injuries
that can result when the SRS
airbag contacts an occupant not
in proper position such as one
thrown forward during pre-acci-
dent braking.
Even when properly positioned,
there remains a possibility that
an occupant may suffer minor
injury such as abrasions and
bruises to the face or arms
because of the SRS airbag de-
ployment force.
. The SRS airbags deploy 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-

!Examples of the types of accidents
in which the driver ’s/driver ’s and
front passenger ’s SRS frontal
airbag(s) will basically not deploy.
The driver ’s and front passenger ’s SRS
frontal airbags are designed basically not to deploy if the vehicle is struck from the
side or from behind, or if it rolls onto its
side or roof, or if it is involved in a low-
speed frontal collision.
1) First impact
2) Second impact
In an accident where the vehicle is
impacted more than once, the driver ’s
and/or front passenger ’s SRS frontal
airbag(s) will deploy only once on the firstimpact.
Example: In the case of a double collision,
first with another vehicle, then against a
concrete wall in immediate succession,
once either or both of the driver ’s and front
passenger ’s SRS frontal airbags is/are
activated on the first impact, it/they will not
be activated on the second impact. &
SRS side airbag and SRS
curtain airbag
The SRS side airbag is stored in the door
side of each front seat seatback, which
bears an “SRS AIRBAG ”label.
Inamoderatetoseveresideimpact
collision, the SRS side airbag on the
impacted side of the vehicle deploys
between the occupant and the door panel
and supplements the seatbelt by reducing
the impact on the occupant ’s chest and
waist. The SRS side airbag operates only
for front seat occupants.
The SRS curtain airbag on each side of
the cabin is stored in the roof side
(between the front pillar and a point over
the rear seat). An “SRS AIRBAG ”mark is
located at the top of each center pillar.
Inamoderatetoseveresideimpact
collision, the SRS curtain airbag on the
impacted side of the vehicle deploys
between the occupant and the side
window and supplements the seatbelt by
reducing the impact on the occupant ’s
head.
