General Description
SEAT BELT SYSTEM
B: CAUTION
•Before starting the work, turn the ignition switch
to OFF, disconnect the battery ground cable and
wait for 20 seconds or more.
•The pretensioner system has a backup power
source. The pretensioner might deploy if you do not
wait for 20 seconds or more before starting work.
•Do not drop or apply any impact to the preten-
sioner.
•If oil, grease or water gets on the pretensioner,
wipe it off immediately with a dry cloth.
•Do not expose the pretensioner to high tempera-
ture or flame.
•Do not allow current to flow through or voltage to
reach the pretensioner. Do not use a circuit tester
to check resistance of the pretensioner.
•Do not disassemble or attempt to repair the pre-
tensioner. If it is dented, cracked or deformed, re-
place it with a new one.
•Do not use the airbag or pretensioner parts from
other vehicles. Always replace parts with new
parts.
•When handling a seat belt with deployed preten-
sioner, wear gloves and goggles. Wash your hands
afterwards.
•Do not reuse a seat belt with deployed preten-
sioner.
•If material from the airbag enters the eyes or con-
tacts skin during deployment, wash it away with
clean water, and then consult a doctor.
