ARNING REGARDING THE SERVICING OF VEHICLES FITTED WITH SRS AIR BAGS AND SEATBELTS WITH PRE-
TENSIONERS
W arning
1. Improper servicing or maintenance of any SRS air bag or pre-tensioner fi\
tted seatbelt component, or related parts, could cause serious injury through the SRS air bag or pre-tensioner fitt\
ed seatbelt being activated unintentionally
or accidentally.
2. The SRS-ECU, the driver’s side air bag module, the passenger side air bag module, the pre-tensio\
ner fitted seatbelts and the clock spring, should be removed if there is a chance o\
f them being affected by heat during
painting work.
• 93ºC and above: the SRS-ECU, the driver’s air bag module, the passenger’s air bag module and the clock spring should be removed.
• 90ºC and above: the pre-tensioner fitted seatbelts should be rem\
oved.
3. Servicing and maintenance of any SRS air bag or pre-tensioner fitted sea\
tbelt components, or related parts, must be performed by an authorized Mitsubishi dealer.
4. Servicing and maintenance of any SRS air bag or pre-tensioner fitted sea\

Caution
1. If Brembo brake callipers are being used take care that they are not scratched by other components or tools
because there is a chance that the paint might peel off. In addition, if any brake fluid gets on the callipers, it
should be wiped off immediately.
2. Parts marked with * should be removed and then fitted for each cylinder in turn.
Jobs to be completed before removal and after fitting
• Removal and refitting of the undercover (Ref Section 51: Front bumper)
• Checking the tension of the drive belt (only after fitting)
• Draining and refilling of the coolant
• Removal and refitting of the air duct
• Removal and refitting of air pipe C
