A: CAUTION
•When servicing a vehicle, be sure to turn the ig-
nition switch to OFF, disconnect the ground cable
from battery, and wait for more than 20 seconds
before starting work.
•The airbag system is fitted with a backup power
source. After disconnecting the battery ground ca-
ble, the airbag may deploy if you do not wait for
more than 20 seconds before starting the service of
airbag system.
•If sensors, airbag module, airbag control module,
pretensioner or harness is deformed or damaged,
replace with new part.
•Do not use the airbag system and pretensioners
on other vehicles. When replacing parts, be sure to
replace them with new ones.
•When checking the airbag system, be sure to
use a digital circuit tester. Use of an analog circuit
tester may cause the airbag to activate erroneously
due to a minimal current inside tester.
•When checking, use a test harness (1). Damage
to connector terminal causes malfunction. Do not
directly put the tester probe on airbag connector
terminal.
•Do not drop the airbag system parts, or keep
them at high temperature over 93°C (199°F), or let
water, oil or grease get on them; the internal parts
may be damaged and reliability greatly lowered.

•When painting or performing sheet metal work
on the front part of the vehicle, including the front
wheel apron, front fender and front side frame, re-
move the front sub sensors and wire harness of air-
