Deployment / Activation Outside of Vehicle
When you intend to return the vehicle to service, deploy
the air bag (inflator) module(s) or activate seat belt
pretensioner(s) outside of the vehicle.
1) Turn ignition switch to LOCK position and remove
key.
2) Wear safety glasses during this deployment /
activation procedure.
3) Check that there is no open, short or damage in
special tools (deployment harness (A) and adapter
cable (B)). If any faulty is found, do not use it and be
sure to use new special tool.
Special tool
(A): 09932–75031
(B): 09932–76510
4) Short two deployment harness leads (1) together by
fully seating one banana plug into the other.
WARNING!
Deployment harness (A) shall remain shorted
and not be connected to 12 volts vehicle
battery till you are ready to deploy air bag
module or activate seat belt pretensioner.

5) Remove air bag (inflator) module(s) or seat belt
pretensioner(s) from vehicle referring to “Driver Air
Bag (Inflator) Module Removal and Installation”,
“Passenger Air Bag (Inflator) Module Removal and
Installation”, “Side-Air Bag (Inflator) Module Removal
and Installation”, “Side Curtain-Air Bag (Inflator)
Module Removal and Installation” or “Front Seat Belt
Removal and Installation in Section 8A”.
WARNING!
• For handing and storage of live air bag
(inflator) module, select place where
ambient temperature below 65 °C (150 °F),
without high humidity and away from
electric noise.
• Always carry live air bag (inflator) module
with trim cover away from you.
• When storing live air bag (inflator) module
or when leaving live air bag (inflator)
module unattended on bench or other
surface, always face trim cover up and
away from surface. It is also prohibited to
place anything on top of the trim cover and
stack air bag (inflator) modules. This is
necessary so that free space is provided to
allow air bag (inflator) module to expand in
the unlikely event of accidental
deployment.
Failure to follow procedures may result in
personal injury.

I4RS0A820084-01
[A]: Always carry air bag (inflator) module with trim cover (air bag opening)
away from body.
[B]: Always place air bag (inflator) module on workbench with trim cover (air
bag opening) up, away from loose objects.

21) Wash your hands with mild soap and water
afterward.
NOTE
Remaining steps are to be followed in the
unlikely event that air bag (inflator) module
did not deploy or seat belt pretensioner did
not activate.

22) Ensure that deployment harness has been
disconnected from 12 volts vehicle battery and that
its two banana plugs have been shorted together by
fully seating one banana plug into the other.
23) Disconnect deployment harness and adapter cable
from air bag (inflator) module or seat belt
pretensioner.
24) Temporarily store undeployed air bag (inflator)
module referring to “Precautions on Service and
Diagnosis of Air Bag System” for details.
25) Contact your local distributor for further assistance.
Deployment / Activation Inside of Vehicle
When the vehicle will be destroyed, or salvaged for
component parts, deploy the air bag modules and/or
activate seat belt pretensioners installed on vehicle.
NOTE
If equipped with the seat belt pretensioners,
activate both side of seat belt pretensioners
at the same time when using special tool (C).

1) Turn ignition switch to LOCK position, remove key
and put on safety glasses.
2) Remove all loose objects from front seats and
instrument panel.
3) Disconnect air bag (inflator) module or seat belt
pretensioner connector as follows.
• For driver air bag (inflator) module [A]
Remove driver side front pillar lower trim and
disconnect driver air bag (inflator) module
connector (1).
• For passenger air bag (inflator) module [B]
Remove passenger side front pillar lower trim and
disconnect passenger air bag (inflator) module
connector (2).
• For side-air bag (inflator) module [C]
Disconnect side-air bag (inflator) module
connectors (3) under front seat cushion.
• For side curtain-air bag (inflator) module [D]
Remove right-side rear quarter lower trim and
disconnect side curtain-air bag (inflator) module
connector (4).
• For seat belt pretensioners (right and left) [E]
Remove both side (driver and passenger side)
center pillar lower trim and disconnect seat belt
pretensioner connectors (5).4) Confirm that each air bag (inflator) module and/or
seat belt pretensioners is securely mounted.

Igniter
Igniter generates high voltage needed to turn on the discharge headlight. It is charged with high voltage raised by the
ballast and it applies voltage pulse as high as about 20,000V to the tungsten electrode in the discharge headlight bulb.
After the discharge headlights light up, the ballast supplies voltage to bulbs.
Discharge headlight bulb
Discharge headlight bulb is used for the low beam. It does not have a filament but xenon gas (1), mercury (3) and
metal iodide (2) sealed in it. It lights up when its tungsten electrodes (4) apply high voltage to these contents.
Fail-safe function of discharge headlight
As the ballast has a fail-safe function which stops supply of the voltage to the igniter when it detects any of the
following condition.
• Ignition switch is set to “HEAD” position while igniter is not connected to discharge headlight bulb
• Discharge headlight does not light up even when lighting switch is set to “HEAD” position.
• Ballast detects a short in the circuit between discharge headlight bulb and ballast when lighting switch is at “HEAD”
position.
Headlight Auto Leveling System Description (If Equipped)S6RW0D9201002
Headlight Auto Leveling System adjusts the optical axis of the headlight automatically to be suitable for the varied
vehicle position while the headlights are lit. It consists of front height sensor (1), rear height sensor (2), headlight
leveling control module (3), headlight leveling actuator (4) and headlight leveling warning light (5).
