SIDE AND CURTAIN AIR BAGS 

M2521000800573

SRS-ECU uses data of the side impact sensor and 
G-sensor (in SRS-ECU) to calculate collision sever-
ity, during side collision. SRS-ECU judges necessity 
of side-airbag and curtain air bag based on the cal-
culated collision severity.

The airbag module is equipped with an inflator that 
does not contain sodium azide.

The air bag is made of nylon and is inflated by the 
gas from the inflator. Then, as the air bag contacts 
the passenger, the gas is discharged through two 
openings of backside of air bag, thus deflating the air 
bag to reduce the impact on the passenger.

PASSENGER'S (FRONT) AIR BAG MODULE

M2521003000628

The passenger’s (front) air bag module consists of 
an air bag, and their fasteners.
The air bag is made from nylon and inflates by the 
gas from the inflator. As a passenger is being 
pressed to the air bag, it deflates, discharging gas 
from two vents at the side of the air bag to reduce the 
shock from the impact.

For the inflator, the gas which is harmless to the 
human body has been used.

The knee air bag module consists of a cover, an air 
bag, an inflator, and the fixing gear relating to those 
parts, and is installed under the steering column. 
Like the driver's and front passenger's air bags, the 
knee air bag is inflated upon a frontal collision for 
better protection of the driver.

For the inflator, the gas which is harmless to the 
human body has been used.

 SIDE-AIRBAG MODULE

M2521004000557

The side-airbag module consists of an air bag, air 
bag cover, inflator and their fasteners. The modules 
are installed in the outer side supports of the driver’s 
and front passenger’s seatbacks. The side-airbags 
help protect the occupants regardless of the seat 
position and seatback angle.

The air bags are compactly folded and stored under 
the cover. On the side of the air bag, there are holes 
through which gas is partially released to alleviate 
shock to the occupant when the air bag is deployed.
For the inflator, the gas which is harmless to the 
human body has been used.

CURTAIN AIR BAG MODULE

M2521000500431

The curtain air bag module consists of an air bag, an 
inflator, and the fixing gear relating to those parts, 
and is installed in the roof side sections (from the 
driver's and the passenger's front pillars to the rear 
pillars).
An inflator that does not contain sodium azide is 
used.

FRONT IMPACT SENSOR

M2521005000646

• The front impact sensor is installed on the head-

lamp support panel upper in the engine room, 
and the analogue G-sensor is housed in the front 
impact sensor.

• The front impact sensor transmits the coded 

acceleration data to SRS-ECU. Based on the 
data, SRS-ECU determines the deployment 
stage of the front air bag, then energises appro-
priate squib.

• SRS-ECU performs the diagnostics of the front 

impact sensor internal components. If a malfunc-
tion occurs, it sets the diagnosis code.

SIDE IMPACT SENSOR

M2521006000575

• The side impact sensors are installed to the lower 

part of the centre pillars on both sides, and the 
analogue G-sensor is housed in the side impact 
sensor.
