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.
Diagnostic Information and Procedures
Repair and Inspection Required after AccidentS7RS0B8104001
After an accident, whether the seat belt pretensioner has been activated or not, be sure to perform checks and repairs
described on “Repair and Inspection Required after Accident in Section 8B”.

Precautions
Precautions in Diagnosing Troubles for Combination MeterS7RS0B9300001
Combination meter uses signals (information) from each control module by CAN communication to control
speedometer, tachometer, engine coolant temp meter, warning light and indicator light (other than air bag warning
light, high beam indicator light, EPS warn ing light and turn signal indicator light). Therefore, check that no DTC is
detected in each module before performing combination me ter symptom diagnosis. If any DTC is detected, correct
trouble indicated by that DTC troubleshooting first.
