If high-pressure car-washing equipment or steam
car-washing equipment is used to wash the vehicle,
be sure to note the following information in order to
avoid damage to plastic components, etc.
• Spray nozzle distance: Approx. 40 cm or more
• Spray pressure: 3,900 kPa or less
• Spray temperature: 82°C or less
• Time of concentrated spray to one point: within
30 sec.
PRECAUTIONS FOR INSTALLATION OF
ON-VEHICLE RADIO TRANSMISSION
EQUIPMENT
M1001015500095
The computers (control unit) for various on-vehicle
electronic equipment are provided with sufficient pro-
tective measures against external radio wave inter-
ference. However, because the on-vehicle radio
transmission equipment may affect adversely the
computers (control unit), pay attention to the follow-
ing precautions for installation.
• Install radio transmission equipment and antenna
(including coaxial cables) 200 mm or more away
from the computers (control unit) for on-vehicle
electronic equipment.
• Because radio wave is radiated from the coaxial
cables of the antenna for radio transmission
equipment, do not route the cables in parallel with
the vehicle wiring harness.
• Install only radio transmission equipment with the
frequencies, output, and radio wave types
described in the table.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
M1001009801120
The driver’s and passenger’s air bag and seat belt
with pre-tensioner is designed to supplement the
driver's and front passenger's seat belts to help
reduce the risk or severity of injury to the driver and
front passenger by activating and deploying both
front air bags in certain frontal collisions. The side-air
bag and the curtain air bag are activated when an
impact exceeds the threshold upon a side collision,
and inflates to protect the heads of the occupants in
the front and rear seats.
The Supplemental Restraint System (SRS) consists
of air bag modules, SRS air bag control unit (SRS-
ECU), front impact sensors, side impact sensor, SRS
warning lamp, clock spring, passenger’s air bag cut
off switch, passenger’s air bag cut off indicator lamp
and seat belt with pre-tensioner. Front air bags are
located in the centre of the steering wheel and above
the glove box. Side-airbags are located inside the
front seatback assemblies. The curtain air bag mod-
ule is installed in the roof side sections (from the

driver's and the passenger's front pillars to the rear
pillars). Each air bag is made up of a folded air bag
and an inflator unit. The SRS-ECU is mounted on the
front of the floor console and has a front air bag saf-
ing G-sensor, front air bag analogue G-sensor. The
front impact sensor is installed out side of the head-
lamp support panel. The side impact sensor is
installed in the lower parts of the centre pillars. The
warning lamp on the instrument panel indicates the
operational status of the SRS. The clock spring is
installed in the steering column. The passenger’s air
bag cut off switch is located above inside the glove
box. The passenger’s air bag cut off indicator lamp is
located above the centre upper panel. The seat belt
pre-tensioner is built into the driver's and passen-
ger's front seat belt retractor.
Only authorized service personnel should do work on
or around the SRS components. Those service per-
sonnel should read this manual carefully before start-
ing any such work.

DANGER
In order to avoid injury to yourself or others
from accidental deployment of the air bag
during servicing, read and carefully follow all
the precautions and procedures described in
this manual.
CAUTION
Do not use any electrical test equipment on or
near SRS components, except those specified on
.
CAUTION
Never attempt to repair the following compo-
nents:
1. SRS-ECU
2. Front impact sensor
3. Clock spring
4. Driver's and passenger's (front) air bag mod-
ules
5. Seat belt with pre-tensioner
6. Side impact sensor
7. Front seatback assembly incorporating side-
airbag module
8. Curtain air bag module
NOTE: If any of these components are diagnosed as
faulty, they should only be replaced, in accordance
with the INDIVIDUAL COMPONENTS SERVICE pro-
cedures in this manual, starting at page .
