Precautions
Precautions on Service and Diagnosis of Seat BeltS6RW0D8100001
WARNING!
If replacing seat belt is necessary, replace buckle and seat belt 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.

Downloaded from www.Manualslib.com manuals search engine 8A-3 Seat Belts:
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 described ELR.The pretensioner is incorporated in retractor 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) 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) that has activated. Replace it with
a new seat belt 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 inform that
driver’s seat belt is unfastened. Seat belt reminder light
located in combination meter 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.
Diagnostic Information and Procedures
Repair and Inspection Required after AccidentS6RW0D8104001
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”.
