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).

35CHANGING WELDED PANELS – ALUMINIUM ALLOY PANELS
ALUMINIUM ALLOY PANELS
Repairing Aluminium Alloy Panels
Precautions when working on sheet metal
1. The main differences to working with sheet steel. (Assuming an ordinary body shop)
OperationAluminium alloy panelSheet steel
HammeringWood or plastic hammerSheet steel hammer
Washer weldingNot possiblePossible
Gas weldingWorkability is poor but possiblePossible
Spot weldingNot possiblePossible
MIG weldingPossible with welder using argon gas and equipment for
aluminium weldingPossible with CO2gas and normal welding
equipment
2. At low temperatures, if subjected to a major impact, strength will deteriorate and it will crack.
3. Coefficient of elasticity is high, so springback (force acting to make material regain original form) is high.
4. Rate of heat transmission is high, and this can cause local thermal expansion.
5. If overheated, it becomes brittle, and strength deteriorates. If heated further, it will melt without discolouration.
(Heat treatment temperature: approx. 250˚C)
MaterialWelding temperature
Aluminium475˚C~660˚C (varies depending on alloy composition)
Sheet steel1500˚C~2500˚C
6. Material is soft, so be careful when selecting polish to use.
Also, since polishing powder is light and easily airborne, wear dust mask and goggles.
7. If strong pressure is used when using a disk sander on the alloy, the friction could cause the aluminium alloy to peel off,
and cause clogging.
8. Disk sanders that become clogged will cause deep scratching on aluminium alloy panels, so replace promptly.
9.Do not use general tools or sanders for sanding sheet steel.
(steel fragments or dust will remain on the sander, causing electrocorrosion with other metal)
10.With MIG welding, shield the local area.Sparks, often difficult to see, can be generated and dispersed over a wide area.
Repairing unevenness
This is basically the same as for sheet steel.However, bear in mind
aluminium alloy characteristics when carrying out this work.
1.Repairing sheet metal
(1) Heat with a torch
Note
a. Heat to the point where heat can be felt on the rear side
of panel with hand wearing a glove.
b. Keep torch moving so as not to overheat one area.
