(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

STEERING – 

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.
