Seat Belt with ELR
The seat belt with emergency locking retractor (ELR) is
designed so that it locks immediately (to prevent the
webbing from being pulled out of the retractor any
further) when any of the following items is detected as
exceeding each set value;
• Speed at which the webbing is pulled out of the retractor.
• Acceleration or deceleration of the vehicle speed.
• Inclination.
Seat Belt with A-ELR
The automatic and emergency locking retractor (A-ELR)
works as an Emergency Locking Retractor (ELR) till its
webbing is pulled all the way out and then on as an
Automatic Locking Retractor (ALR ) till it is retracted fully.
ALR: Automatically locks when the webbing is pulled out
from the retractor and allowed to retract even a little.
Then the webbing can not be pulled out any further,
unless it is wound all the way back into the retractor,
which releases the lock and allows the webbing to be
pulled out.
Seat Belt with ELR and Pretensioner
The seat belt with ELR and a pretensioner has a
pretensioner mechanism whic h operates in linkage with
the air bag in addition to the described ELR.
The pretensioner is incorporated in retractor assembly
and controlled by SDM as one of air bag system
components. It will be activated at the same time as the
driver and passenger air bag module when an impact at
the front of vehicle exceeds the specified value.
When servicing seat belt (retractor assembly) with
pretensioner, be sure to observe all WARNINGS and
CAUTIONS and “Precautions on Service and Diagnosis
of Air Bag System in Section 8B”. CAUTION!
Do not reuse the seat belt pretensioner
(retractor assembly) that has activated.
Replace it with a new seat belt assembly and
buckle together as a set. For checking
procedure of its activation, refer to “Repair
and Inspection Required after Accident in
Section 8B”.
Seat Belt Remainder
When driver’s seat belt is unfastened (under the
following conditions), seat belt reminder light and
warning buzzer inform that driver’s seat belt is
unfastened. Seat belt reminder light located in
combination meter and warning buzzer located inside
BCM operate as follows:
• Seat belt reminder light comes on when driver’s seat belt is unfastened while igni tion key switch is at ON
position.
• If vehicle speed exceeds 15 km/h with seat belt unfastened, warning buzzer operates for
approximately 95 seconds and seat belt reminder light
flashes synchronously with buzzer. When warning
buzzer stops operating, seat belt reminder light is
turned on.
• If driver’s seat belt state is changed from “fastened” to “unfastened” while vehicle speed is above 15 km/h,
warning buzzer operates for approximately 95
seconds and seat belt reminder light flashes
synchronously with buzzer. When warning buzzer
stops operating, seat belt reminder light is turned on.

SDM
WARNING!
Never power up air bag system when SDM is
not rigidly attached to the vehicle. Otherwise,
personal injury may result.
CAUTION!
After detecting one time of such collision as
to meet deployment conditions, SDM must
not be used. Refer to “Air Bag Diagnostic
System Check” when checking SDM.
• Never attempt disassembly of SDM.
• When storing SDM, select a place where neither high temperature nor high humidity is anticipated and oil,
water and dust are kept off.
• If SDM has been dropped, replace it with a new one.
• If SDM installation part of floor was damaged, repair that part completely before reinstallation.
• All SDM and mounting bracket fasteners must be carefully torqued and the arrow must be pointed
toward the front of the vehicle to ensure proper
operation of the air bag system. Live (Undeployed) Air Bag (Inflator) Modules
Special care is necessary when handling and storing a
live (undeployed) air bag (inflator) modules.
The rapid gas generation produced during deployment
of the air bag could cause the air bag (inflator) module,
or an object in front of the air bag (inflator) module, to be
thrown through the air in the unlikely event of an
accidental deployment.
WARNING!
Never attempt to measure the resistance of
the air bag (inflator) modules (driver,
passenger and side of both sides and curtain
of both sides). It is
very dangerous as the
electric current from the tester may deploy
the air bag.

• Never attempt disassembly of the air bag (inflator) modules.
• If any abnormality is found, be sure to replace it with
new one as an assembly.
• When an abnormality is noted as existing in the live (undeployed) air bag (inflator) module, be sure to
deploy it before discarding it.
• When grease, cleaning agent, oil, water, etc., got on the air bag (inflator) modules (driver, passenger, side
of both sides and curtain of both sides), wipe it off
immediately with a dry cloth.
• If air bag (inflator) module was dropped from a height of 90 cm (3 ft) or more, it should be replaced with a
new one as an assembly.
WARNING!
• For handling and storage of a live air bag (inflator) module, select a place where the
ambient temperature below 65 °C (150 ° F),
without high humidity and away from
electric noise.
• When carrying a live air bag (inflator) module, make sure the bag opening is
pointed away from you. In case of an
accidental deployment, the bag will then
deploy with minimal chance of injury.
Never carry the air bag (inflator) module by
the wires or connector on the underside of
the module.
Otherwise, personal injury may result.
WARNING!
When placing a live air bag (inflator) module
on bench or other surface, always face the
bag up, away from the surface. As the live
passenger air bag (inflator) module must be
placed with its bag (trim cover) facing up,
place it on the workbench with a slit (1) or
use the workbench vise (2) to hold it securely
at its lower mounting bracket (3).
It is also prohibited to place anything on top
of the trim cover and stack air bag (inflator)
modules.
This is necessary so that a free space is
provided to allow the air bag to expand in the
unlikely event of accidental deployment.
Otherwise, personal injury may result.
Live (Inactivated) Seat Belt Pretensioner
Special care is necessary when handling and storing a
live (inactivated) seat belt pretensioners.
Also, when the seat belt pretensioners activate, gas is
generated and the seat belt (1) is retracted into the
retractor assembly (2) quickly.
Note, therefore, that if they activate accidentally, the seat
belt pretensioners and other object(s) around them may
be thrown through the air.
