Precautions on Service and Diagnosis of Seat
Belt

S6JB0B8100001

WARNING

If replacing seat belt is necessary, replace
buckle and seat belt assembly together as a
set. This is for the reason of ensuring locking
of tongue plate with buckle. If these parts are
replaced individually, such a locking
condition may become unreliable. For this
reason, SUZUKI will supply only the spare
buckle and seat belt assembly in a set part.

Before servicing or replacing seat belts, refer to the
following precautionary items.

• Seat belts should be normal relative to strap retractor

and buckle portions.

• Keep sharp edges and damaging objects away from

belts.

• Avoid bending or damaging any portion of belt buckle

or latch plate.

• Do not bleach or dye belt webbing. (Use only mild

soap and lukewarm water to clean it.)

• When installing a seat belt anchor bolt, it should be

tightened by hand at first to prevent cross-threading
and then to specified torque.

• Do not attempt any repairs on retractor mechanisms

or retractor covers. Replace defective assemblies with
new replacement parts.

• Keep belts dry and clean at all times.
• If there exist any parts in question, replace such parts.
• Replace belts whose webbing is cut or otherwise

damaged.

• Do not put anything into trim panel opening which seat

belt webbing passes through.

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 which operates in linkage with
the air bag in addition to the 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 (if equipped)
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 ignition 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.
