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 inad vertent firing of the air bag) or to the driver and
paassenger (from renderin g 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 th is manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before begi nning 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 (*).

Power steering has been adopted in all vehicles to
make the steering system easier to handle.
FEATURES
•A 4-spoke steering wheel is used.
•MOMO leather-wrapped 3-spoke steering wheel
is used.
•A steering column has a shock absorbing mecha-
nism and a tilt steering mechanism.
•Integral-type rack and pinion gear with high rigid-
ity and excellent response is used.
•A vane type pump with a fluid flow rate control
system which change steering effort according to
the engine speed is used.
•The separate plastic resin oil reservoir is used to
reduce weight and to make the fluid level check
-
ing easier.

6. Check whether or not the hydraulic pressure is the standard value when no-load conditions are
created by fully opening the shut-off valve of the
pressure gauge.
Standard value: 0.2 − 0.7 MPa
7. If it is not within the standard value, the probable cause is a malfunction of the oil line or steering
gear, so check these parts and repair as
necessary.
8. Turn the steering wheel all the way to the left or right; then check whether or not the retention
hydraulic pressure is the standard value.
Standard value: 8.8 − 9.5 MPa
9. If not the standard value, overhaul the steering gear. Remeasure fluid pressure.
10. Remove the special tools, and then tighten the
pressure hose to the specified torque.
Tightening torque: 57 ± 7 N⋅m
11. Bleed the system (Refer to P.37-14).

WARNING
•If the vehicle continues to be driven after
the collision absorbing mechanism has
operated, the steering column shaft may
be damaged while it is in use.
•If there is a slack in the one-way capsule,
do not attempt to repa ir it but replace the
steering column shaft assembly.
Inspection Procedure
1. Remove the lower and upper column covers.
CAUTION
Do not release the tilt lever until the steering col-
umn has been installed to complete this inspec-
tion procedure.
2. Ensure that the tilt lever is in the lock position.
NOTE: If not, place the tilt lever in the lock posi-
tion.

4. Hold the one way capsule as shown, and then try
to lock them. If there is a slack in either of the
capsules, replace the steering column shaft
assembly.
NOTE: When installing a new steering column
shaft assembly, place the tilt lever in the lock posi
-
tion, if it is not in place.
CAUTION
•Be careful that nothing is pinched between
the one-way capsules and the body.
•Do not release the tilt lever until the steering
column has been installed to complete this
inspection procedure.
5. If no problem is found during the inspection, tighten the steering column mounting bolts to the
specified torque.
Tightening torque: 12 ± 2 N⋅m

ASSEMBLY REMOVAL
CAUTION
The tilt lever should be held in the lock position
until the steering column shaft is installed to the
vehicle. If the steering column is removed with
the tilt lever released, or the tilt lever is released
after the steering column shaft was removed
from the vehicle, the steering column can not be
reinstalled correctly. If the steering column is
installed incorrectly, the collision energy absorb
-
ing mechanism may be damaged.
1. Ensure that the tilt lever is in the lock position, and remove the steering column mounting bolts.
