Precautions on Disposal of Air Bag and Seat
Belt Pretensioner
S6RW0D8200003
Do not dispose of the live (undeployed) air bag (inflator)
modules and the live (inactivated) seat belt
pretensioners.
When disposal is necessary, be sure to deploy / activate
the air bag and seat belt pretensioner according to
deployment / activation procedure described in “Air Bag
(Inflator) Module and Seat Belt Pretensioner Disposal”.
WARNING!
Failure to follow proper air bag (inflator)
module and seat belt pretensioner disposal
procedures can result in air bag deployment
and pretensioner activation which could
cause personal injury. Undeployed air bag
(inflator) module and inactivated seat belt
pretensioner must not be disposed of
through normal refuse channels.
The undeployed air bag (inflator) module and
inactivated seat belt pretensioner contain
substances that can cause severe illness or
personal injury if the sealed container is
damaged during disposal.

General Description
Air Bag System ConstructionS6RW0D8201001
There are two types of air bag system in this model
depending on vehicle specification.
One is 4-channel air bag system and other is 8-channel
air bag system.
4-channel air bag system consists of the following parts.
• Driver and passenger air bag (inflator) modules
• Driver and passenger seat belt pretensioners
• Forward impact-sensor
•SDM
8-channel air bag system consists of the following
component.
• Driver and passenger air bag (inflator) modules
• Driver and passenger seat belt pretensioners
• Driver and passenger side-air bag (inflator) modules
• Driver and passenger side curtain-air bag (inflator)
modules
• Forward impact-sensor
• Driver and passenger side impact-sensors
•SDM
With the air bag system which includes front air bags for
both the driver’s and passenger’s sides as well as the
seat belt pretensioners, the sag of the seat belt is taken
up (for seat belt with pretensioner), the driver air bag
(inflator) module is deployed from the center of the
steering column and the passenger air bag (inflator)
module from the top of the instrument panel in front of
the front passenger seat in occurrence of a front collision
with an impact larger than a certain set value to
supplement protection offered by the driver and front
passenger seat belts.
In addition, with the air bag system which includes side-
air bags and side curtain-air bags for both the driver’s
and passenger’s side (8-channel system).
Side-air bag (inflator) module is deployed from the side
of the seat back in occurrence of a sideward collision
with an impact larger than a certain set value.Side curtain-air bag (inflator) module is deployed from
the roof side in occurrence of a sideward collision with
an impact larger than a certain set value.
For details of air bag system input / output, refer to “Air
Bag System Input / Output Table”.

• Improperly formed or damaged terminals.
Check each connector terminal in problem circuits
carefully to ensure good contact tension by using the
corresponding mating terminal included in the
connector test adapter kit (special tool).
If contact tension is not enough, reform the terminal to
increase contact tension or replace it.
Special tool
(A): 09932–76010 Connector test adapter kit
• Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor
connection by shaking it by hand lightly. If any
abnormal condition is found, change the wire harness
assembly or component parts with new ones.
• Wire insulation which is rubbed through, causing an
intermittent short as the bare area touches other
wiring or parts of the vehicle.
• Wire broken inside the insulation. This condition could
cause a continuity check to show a good circuit, but if
only 1 or 2 strands of a multi-strand-type wire are
intact, resistance could be far too high.
Repair and Inspection Required after AccidentS6RW0D8204048
CAUTION!
• All air bag system components, including
the electrical harness (component
mounting points), must be inspected after
an accident. If any components are
damaged or bent, they must be replaced
even if air bag system activation did not
occur.
• Never use air bag system parts from
another vehicle.
• Do not attempt to service the parts below.
Service of these parts is by replacement
only.
– Driver / Passenger air bag (inflator)
modules
– Driver / Passenger side-air bag (inflator)
modules
– Driver / Passenger side curtain-air bag
(inflator) modules
– Driver / Passenger seat belt
pretensioners
– Forward impact-sensor
– Driver / Passenger side impact-sensors
–SDM
– Contact coil and combination switch
assembly
– Air bag wire harness in main harness,
instrument panel harness, floor harness,
passenger air bag harness, side-air bag
harness and side curtain-air bag
harness.
• Proper operation of the sensors and air
bag system requires that any repairs to the
vehicle structure return it to its original
production configuration.

With more passenger(s) or luggage in the vehicle, the vehicle position differs from that in such vehicle state with one
person and no load in the vehicle and angle of the headlight optical axis varies accordingly. This system automatically
adjusts the varied angle to maintain the optical axis properly.
Front and rear height sensors
Front height sensor (1) is installed to the front suspension frame (2) respectively and connected to the lower arm (4)
with the link (3). Also rear height sensor is installed to the rear floor center cross member (5) respectively and
connected to the rear axle (6) with the link (3). Each height sensor converts vertical movement of the lower arm into
the resistance value and outputs the detected change in the vehicle position as a voltage signal to the headlight
leveling control module.
Headlight leveling control module
Headlight leveling control module is installed at the inside of the glove box. It uses the headlight ON signal from the
lighting switch, vehicle speed signal from BCM and vehicle position signal from height sensors to calculate the angle
of the headlight optical axis to be corrected. Then it adjusts the optical axis angle of headlight based on the calculated
angle value by driving the headlight leveling actuator so that proper headlight aiming is obtained. Also, when any
abnormality is detected in the system, the headlight leveling control module makes the headlight leveling warning light
in the combination meter light up to warn the driver of an abnormality in the system.
Fail-safe function of headlight leveling control module
Headlight leveling control module has a fail-safe function which operates as follows.
