SEAT BELT SYSTEM
General Description
B: CAUTION
 Before starting, turn the ignition switch to OFF,
disconnect the battery ground cable and wait for 20
seconds or more.
 The pretension 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 a deployed pre-
tensioner, wear gloves and goggles. Wash your
hands afterwards.
 Do not re-use a seat belt with a deployed preten-
sioner again.
 Be sure to deploy pretensioner before disposal.

 If the material gets in your eyes or on your skin
during deployment, wash it away with clean water,
and then consult a doctor.
