Precautions to be taken when servicing vehicles with seatbelts fitted with SRS Airbag and Pretensioners
Precautions
1. Incorrect inspection or servicing of SRS airbag and pretensioner fitted seatbelt parts, as well as any related
components, could lead to major damage or nonoperation as a result of sudden, unintentional operation of SRS
airbag and pretensioner fitted seatbelts (incorrect deployment).
2.In cases where heating from painting processes occurs, the SRSECU, driver side airbag module, passenger side
airbag module, pretensioner fitted seatbelts, and cross springs, should be removed.
• 93°C and above: SRSECU, driver side airbag module, passenger side airbag module, cross springs
• 90°C and above: pretensioner fitted seatbelts3.Inspections and servicing of SRS airbag and pretensioner fitted seatbelt parts and any related components must,
without fail, be done by a Mitsubishi Motors authorized dealer.
4. Inspections and servicing of SRS airbag and pretensioner fitted seatbelt parts and any related components must be
done paying scrupulous attention to the relevant service manual (particularly in the case of Group 52B – SRS
airbags).
