Head Impact Protection Structure
The construction of the pillar trims and roof side adopted gives full consideration to protecting the heads of
the driver and passengers from injury in the event of a collision. In addition, impact absorbing material has
been built into the interior of each pillar trim and roof side which are most likely to be the cause of head
injuries in a collision.
SRS Airbag
SRS airbags are standard for the driver and front passenger seats on all models. In the event of a frontal collision,
the airbags function to support the seatbelts in reducing the impact to the driver and front passenger. Also,
SRS side airbags are available as a option. The SRS side airbags have been designed to help reducing the
impact energy that is transmitted to the driver and front passenger in the event of a side collision.
Seatbelt with Pre-tensioner and Force-limit-
ing Mechanism
Three-point type seatbelts with pre-tensioner and force limiter are standard on the front seats of all models.
An ELR-equipped seatbelt is provided on the driver's side and an ALR/ELR selectable one on the passenger
side.
Three sets of 3-point type
ALR/ELR selectable seatbelts are fitted on the rear seats.

INTERNAL TRUNK RELEASE HANDLE
An internal trunk release handle is included inside the trunk in case a person inadvertently locks himself with-
in the trunk and needs to free himself. The handle is made of phosphorescent so that it is visible in the trunk
for a while even after the trunk has been closed.

CRS (Child Restraint System) lower anchorage for securing child seats, which complies with FMVSS225,
has been provided behind the seat cushion of both outer rear seats.

Three CRS anchor brackets for securing a child seat have been provided above the package tray trim.

SEAT BELT
1. General

The front seats are provided with an electrical sensing type seat belt pretensioner and a seat belt force limit-
er. In the beginning of a collision, the seat belt pretensioner instantly pulls up the seat belt thus providing
the excellent belt's effectiveness in restraining the occupant.
When the impact of a collision causes the tension of the seat belt applied to the occupant to reach a predeter-
mined level, the force limiter restrains the tension, thus controlling the force applied to the occupant's chest
area.

In accordance with the ignition signal from the airbag sensor assembly, the seat belt pretensioner activates
simultaneously with the deployment of the SRS airbags for the driver and front passenger.

The passenger seats are provided with ALR (Automatic Locking Retractor) / ELR (Emergency Locking
Retractor) seat belts.
2. Seat Belt Pretensioner
General
The pretensioner mechanism mainly consists of a rack, pinion gear, planetary gear, clutch mechanism, and
a bobbin.
During the deployment of this pretensioner mechanism, the gas pressure from the gas generator pushes the
rack down and retracts the seat belt via the pinion gear, planetary gear, clutch mechanism, and bobbin.

(d) Check the valve overall length.
Standard overall length:
Intake 89.25 mm (3.5138 in.)
Exhaust 87.90 mm (3.4606 in.)
Minimum overall length:
Intake 88.95 mm (3.5020 in.)

11. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
(b) Check the valve seating position.
Apply a light coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate valve.
(c) Check the valve face and seat for the following:

If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.

If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.

Check that the seat contact is in the middle of the
valve face with the following width:
1.0 ± 1.4 mm (0.039 ± 0.055 in.)
If not, correct the valve seats as follows:
(1) If the seating is too high on the valve face, use 20°
and 45° cutters to correct the seat.
(2) If the seating is too low on the valve face, use 75°
and 45° cutters to correct the seat.
