INFLATION OF TIRES
Tire pressure, in cold condition (after vehicle has setfor
three hours or more, and driven less than one mile),
should
be checked monthly or before any extended
trip. Tire pressure increases
approximately 15% when
the tires become hot during driving. Tire pressure
specification is shown on the
label located on the left
door lock pillar (Fig. 3E-5).
Fig.
3E-5
NOTE:
Check the tire pressure whenever irregular wear is
found. Tire
inflation greatly affects tire wear. If the
alignment check does not reveal any alignment
problems,
check the condition of the shock absorbers
and
wheel/tire balance.
WHEELS AND TIRES 3E-3
DIAGNOSIS LIST
If the following conditions are noted, rotation is
required.
1. Front tire wear is different from rear.
2. Uneven wear exists across the tread of any tire.
3. Left and right front tire wear is unequal.
4. Left and right rear tire wear is unequal.
If
the following conditions are noted, check the wheel
alignment.
1. Left and right front tire wear is unequal.
2. Uneven wear exists across the tread of any tire.
3. Front tire treads have scuffed appearance with
"feather" edges on one side of tread ribs or
blocks.
4. There is cupping, flat spotting etc.
Higher than recommended pressure can cause:
1. Hard ride.
2. Poor steering stability.
3. Rapid and uneven wear at center of the tread.
Lower than recommended pressure can cause:
1. Tire squeal on turns.
2. Hard steering.
3. Rapid and uneven wear on the edges of the tread.
4. Tire rim bruises and rupture.
5. Tire cord breakage.
6. High tire temperatures.
7. Reduced handling.
8. Reduced fuel economy.
Unequal pressure on same axle can cause:
1. Uneven braking
2. Steering lead.
3. Reduced handling.
4. Swerve on acceleration

W CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were removed.
If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct
part
number fastener is not available, a fastener of equal size and strength (or stronger) may be used.
Fasteners
that are not reused, and those requiring thread locking compound, will be called out. The correct
torque value must be used when installing fasteners that require it. If the above conditions are not
followed, parts or system damage could result.

W WARNING
TO AVOID DEPLOYMENT WHEN TROUBLE­
SHOOTING
THE SRS SYSTEM, DO NOT USE
ELECTRICAL TEST EQUIPMENT, SUCH AS
BATTERY-POWERED OR A/C-POWERED VOLT­
METER, OHMMETER, ETC., OR ANY TYPE OF
ELECTRICAL EQUIPMENT OTHER THAN SPE­
CIFIED IN THIS MANUAL. DO NOT USE A NON­
POWERED
PROBE-TYPE TESTER.
INSTRUCTION IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PER­
SONAL INJURY MAY RESULT.
This steering
wheel and column repair section covers
the Supplemental Restraint System (SRS) steering
column. The following repair procedures are specific
to SRS Components. When servicing a vehicle
equipped with Supplemental Restraint System, pay
close attention to all WARNINGS and CAUTIONS.
For detailed explanation about SRS, refer to Section
9J "SUPPLEMENTAL
RESTRAINT SYSTEM (SRS)" of
this manual.
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of injury to the driver of the vehicle.
2. The ignition switch and lock are mounted con­
veniently on the column.
3. With the column mounted lock, the ignition and
steering operation can be
locked to prevent theft
of the vehicle.
The column may be disassembled and reassembled.
To insure the energy absorbing action, it is important
that the specified screws, bolts and nuts be used only
as designated and that they are tightened to the
specified torque.
When the column is removed from the vehicle, a
sharp
blow on the end of steering shaft or shift lever,
leaning
on the column assembly, or dropping the
assembly could shear or loosen the fasteners that
maintain column rigidity.

\f' WARNING
THE INFLATOR MODULE SHOULD ALWAYS BE
CARRIED WITH THE URETHANE COVER AWAY
FROM YOUR BODY AND SHOULD ALWAYS BE
LAID ON A FLAT SURFACE WITH THE URE­
THANE SIDE UP. THIS IS NECESSARY BE­
CAUSE A FREE SPACE IS PROVIDED TO ALLOW
THE AIR CUSHION TO EXPAND IN THE UN­
LIKELYEVENT OF ACCIDENTAL DEPLOYMENT.
OTHERWISE, PERSONAL INJURY
MAY RESULT
(FIG. 3F4-5).
Fig. 3F4-5
The
Inflator module consists of a cover, air bag,
inflator, and retainer.
Inspect the Inflator module
mainly for the following:
1) Check for holes, cracks, severe blemishes and
deformation on the cover.
2) Check that the retainer is not deformed.
3) Check for defects such as damage and breakage in
the lead
wire ofthe squib.
If an abnormality is found as the result of the in­
spection, replace the
Inflator module with a new one.

STEERING WHEEL REPLACEMENT
\f' CAUTION:
Once the steering column is removed from the
vehicle, the
column is extremely susceptible to
damage. Dropping the column assembly on its
end
could collapse the steering shaft or loosen
the
slide block which maintains column rigidity.
Leaning on the column assembly could cause the
jacket
to bend or deform. Any of the above
damage could
impair the column's collapsible
design. If it is necessary to remove the steering
wheel, use
only the specified steering wheel
puller.
Under no conditions should the end of the
shaft be hammered upon,
as hammering could
loosen
slide block which maintains column
rigidity.
