SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-3

GENERAL DESCRIPTION

M1524000100730

.

WARNING

Improper service could result in serious 
injury of the service personnel or the pas-
senger.

.

The SRS is designed to supplement the front seat 
belts. It reduces injury to the driver(s) and the front 
passenger(s) by deploying air bag(s) in case of a 
head-on collision.
The SRS front air bags from an advanced air bag 
system together with sensors at the vehicle and sen-
sors attached to front seats.

.

Side-airbag systems in the front seats are activated 
when side impacts exceed a criteria to protect the 
occupants’ upper bodies.

.

The seat belts with pre-tensioner work simulta-
neously with the SRS. The seat belt incorporating the 
pre-tensioner automatically winds the seatbelt upon 
front impact to reduce forward shifting of the driver’s 
and passenger’s. The seat belt use status is used to 
control the activation and deactivation of the pre-ten-
sioner.

.

The SRS consists of four air bag modules, SRS air 
bag control unit (SRS-ECU), two front impact sen-
sors, two side impact sensors, SRS warning light, 
clock spring, seat belt pre-tensioner, seat belt switch, 
seat slide sensor. Air bag modules are located in the 
center of the steering wheel and above the glove 
box. Side-airbags are located inside the front seat-
back assemblies. Each air bag consists of a folded 
air bag and an inflator unit. The SRS-ECU placed on 
the forefront of the floor monitors the system and has 
a front air bag safing G-sensor, front air bag analog 
G-sensor and a side-airbag safing G-sensor. The 
front impact sensor is assembled in the radiator sup-
port panel to monitor impact in case of front impact. 
The side impact sensors inside the center pillars 
monitor the shock incurred by the sides of the vehi-
cle. The SRS warning light on the combination meter 
indicates the operational status of the SRS. The 
clock spring is installed in the steering column. The 
seat belt pre-tensioner is built into the driver's and 
passenger'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.
