Service or maintenance of any SRS component or SRS-related component must be performed only at an

authorized MITSUBISHI dealer.

•

MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental

Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any

SRS-related component.

NOTE

The SRS includes the following components: SRS air bag control unit, SRS warning light, front impact sensors, driver’s and

passenger’s (front) air bag modules, knee air bag module, side-airbag module, curtain air bag module, side impact sensors,

seat belt pre-tensioners, clock spring, and interconnecting wiring. Other SRS-related components (that may have to be
