WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING
•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
paassenger (from rendering the SRS inoperative).
•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, air bag module,
clock spring, and interconnecting wiring. Other SRS-related components (that may have to be removed/installed in connection
with SRS service or maintenance) are indicated in the table of contents by an asterisk (*).

ON-VEHICLE SERVICE
STEERING WHEEL FREE PLAY CHECKM1372001000311
1. With the engine running (hydraulic operation), set
the front wheels straight ahead.
2. Measure the play on the steering wheel
circumference before the wheels start to move
when slightly moving the steering wheel in both
directions.
Limit: 30 mm
3. When the play exceeds the limit, check for the
play on the steering shaft and steering linkage
connection. Correct or replace.
4. If the free play still exceeds the limit value, set the
steering wheel straight ahead with the engine
stopped. Load 5 N towards the steering wheel
circumference and check the play.
Standard value (steering wheel play with the
engine stopped): 10 mm or less
5. If the play exceeds the standard value, remove
the steering gear (Refer to P.37-24) and check
the total pinion torque (Refer to P.37-27).
STEERING ANGLE CHECKM1372001100374
1. Place the front wheel on a turning radius gauge
and measure the steering angle.
Standard value:
2. If the steering angle is not within the standard
value, adjust the toe-in as follows.
Standard value:
at the centre of tyre tread: 1 ± 2 mm
Toe angle (per wheel): 0°03' ± 06'
3. Loosen the lock nut, and unclip the bellows.
4. Adjust the toe-in by turning the left and right tie
rod turnbuckles by the same amount (in opposite
directions).
NOTE: The toe will move out as the left
turnbuckle is turned toward the front of the vehicle
and the right turnbuckle is turned toward the rear
of the vehicle.
5. Tighten the lock nut to the specified torque, and
tighten the bellows by the clip.
Tightening torque: 40 ± 5 N⋅m
6. Recheck the steering angle.

STEERING WHEEL RETURN TO CENTRE
CHECK
M1372001800317
Conduct a road test:
1. Make both gradual and sudden turns and check
the steering wheel return.
2. At a vehicle speed of approximately 35 km/h, turn
the steering wheel 90°, hold a few seconds, then
release. If the steering wheel then returns 70° or
more, the return can be judged satisfactory.
NOTE: There will be a momentary feeling or
"heaviness" when the wheel is turned quickly, but
this is not abnormal (Oil pump discharge amount
is especially apt to be insufficient during idling).
DRIVE BELT TENSION CHECKM1372001900392
For vehicles with 1300 and 1600 engine, refer to
GROUP 11A, On-vehicle Service − Drive Belt
Tension Check P.11A-7.
For vehicles with 2000 engine, refer to GROUP 11C,
On-vehicle Service − Drive Belt Tension Check
P.11C-7.
FLUID LEVEL CHECKM1372002000284
1. Park the vehicle on a flat, level surface.
2. Start the engine, and then turn the steering wheel
several times to raise the temperature of the fluid
to approximately 50 − 60°C.
3. With the engine running, turn the wheel all the
way to the left and right several times.4. Check the fluid in the oil reservoir for foaming or
milkiness. Check the difference of the fluid level
when the engine is stopped, and while it is
running. If the change of the fluid level is 5 mm or
more, air bleeding should be done.
FLUID REPLACEMENTM1372002100333
1. Raise and support the front wheels.
2. Disconnect the return hose connection, and then
connect a vinyl hose to the return hose, and drain
the fluid into a container.
3. Disconnect the ignition coil connectors (Refer to
GROUP 16, Ignition Coil P.16-38or P.16-39).
4. While operating the starter motor intermittently,
turn the steering wheel all the way to the left and
right several times to drain all of the fluid.
5. Connect the return hose securely, and then
secure with the clip.
6. Fill the oil reservoir with specified fluid up to
between "MAX" and "MIN" marks, and then bleed
the air.
Specified fluid: ATF DEXRON III or DEXRON
II
POWER STEERING SYSTEM AIR
BLEEDING
M1372002200330
Perform air bleeding procedure as necessary after
replacing the steering gear or the steering fluid lines.
1. Raise and support the front wheels.
2. Disconnect the ignition coil connectors (Refer to
GROUP 16, Ignition Coil P.16-38 or P.16-39).
