equipment to repair. Replace the faulty harness
with a new genuine part.

• Install the wiring harness securely with the spec-
ified clips to avoid interference or tangled with other
parts.

• 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 wiring harness of
airbag system.
• When painting or performing sheet metal work
on the side of the vehicle or floor pan, around rear
crossmember, including the side sill, center pillar
and front and rear doors, remove the side airbag
sensors, curtain airbag sensor, satellite safing sen-
sor and wiring harness of the airbag system.

• Do not use the airbag or pretensioner parts from
other vehicles. Always replace the defective parts
with new parts.
• Never reuse a deployed airbag module and pre-
tensioner.
