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 .
