Precautions
Precautions on Service and Diagnosis of Seat
Belt
S7RS0B8100001
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 repair s 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.

The air bag system is designed to activate only in severe
frontal and sideward collisions. It is not designed to
activate in rear impacts, rollovers, or minor frontal and
sideward collisions, since it would offer no protection in
those types of accidents.
