WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES

WARNING!

(1) Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to personal

injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and passenger (from
rendering the SRS inoperative).

(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized

MITSUBISHI dealer.

(3) 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-ECU, SRS warning lamp, air bag module, clock spring and interconnecting

General Information

37A-2

GENERAL INFORMATION

A 4-spoke type steering wheel has been mounted.
The power steering is an integral rack and pinion
type that combines the steering gear and linkage
into one light-weight and compact assembly.

The steering system uses a vane oil pump with
a fluid flow control system, so that steering effort
varies with engine speed.
