Cautionary Note regarding servicing of vehicles fitted with SRS airbags and/or seatbelts with
pre-tensioner systems.
Warnings:
1. Incorrect inspection or servicing of a component part of the SRS airbag system or seatbelt pre-tensioner system, or
a part relating to these systems, may cause accidental operation (deployment) of the SRS airbag or seatbelt pre-
tensioners, or may cause these systems to be disabled, leading in either case the risk of serious injury.
2. If parts may be affected by heat during painting operations, then those parts must be removed in advance. This
applies to the SRS-ECU, airbag modules (driver’s sear and front passenger’s seat), clock springs, front impact
sensors, side impact sensors, and pre-tensioner seatbelts.
• 93ºC or above : SRS-ECU, airbag modules (driver’s sear and front passenger’s seat), clock springs, front impact
sensors, side impact sensors
• 90ºC or above : Pre-tensioner seatbelts
3. The component parts of the SRS airbag system or seatbelt pre-tensioner system, and parts relating to these
systems, must always be inspected and serviced by a Mitsubishi dealer.
4. Service personnel must read the relevant service manuals (particularly, Section 52B – SRS Airbags) carefully and
thoroughly, before inspecting or servicing the component parts of the SRS airbag system or seatbelt pre-tensioner
system, and parts relating to these systems.
