Irregular and/or Premature Wear DescriptionS6RW0D2401003
Irregular and premature wear has many causes. Some
of them are as follows: incorrect inflation pressures, lack
of tire rotation, driving habits, improper alignment.
If the following conditions are noted, tire rotation is
necessary:
• Front tire wear is different from rear’s.
• Uneven wear exists across tread of any tires.
• Both sides of front tire wears are not even.
• Both sides of rear tire wears are not even.
• There is cupping, flat spotting, etc.
A wheel alignment check is necessary if following
conditions are noted:
• Both sides of front tire wears are not even.
• Wear is uneven across the tread of any front tire.
• Front tire treads have scuffed appearance with
“feather” edges on one side of tread ribs or blocks.
Wear Indicators DescriptionS6RW0D2401004
Original equipment tires have built-in tread wear
indicators (1) to show when they need replacement.
These indicators (1) will appear as 12 mm (0.47 in.) wide
bands when the tire tread depth becomes 1.6 mm (0.063
in.).
When the indicators (1) appear in 3 or more grooves at 6
locations, tire replacement is recommended.
Radial Tire Waddle DescriptionS6RW0D2401005
Waddle is side to side movement at the front and/or rear
of the vehicle. It is caused by the steel belt not being
straight within the tire. It is most noticeable at a low
speed, 8 to 48 kph (5 to 30 mph).
It is possible to locate the faulty tire by road testing the
vehicle. If it is on the rear, the rear end of the vehicle
shakes from side to side or “waddles”. To the driver in
the seat, it feels as though someone is pushing on the
side of vehicle.
If the faulty tire is on the front, waddling is more visual.
The front sheet metal appears to be moving back and
forth and the driver feels as though he is at the pivot
point in vehicle.
Waddle can be quickly diagnosed by using Tire Problem
Detector (TPD) and following the equipment
manufacture’s recommendations.
If TPD is not available, an alternative method of
substituting known-good tire / wheel assemblies can be
used as follows, although it takes a longer time.
1) Ride vehicle to determine whether the front or rear
waddles.
2) Install tires and wheels that are known to be good
(on similar vehicle) in place of those on waddling end
of vehicle. If waddling end cannot be identified,
substitute rear ones.
3) Road test again. If improvement is noted, reinstall
originals one at a time till waddle causal tire is found.
If no improvement is noted, install known-good tires
in place of all four. Then reinstall originals in the
same manner.
[A]: Hard Cornering, under inflation or lack of tire rotation
[B]: Incorrect wheel alignment, tire construction not uniform or wheel
heavy acceleration

Equipment manufacture’s recommendations
Radial Tire Lead / Pull DescriptionS6RW0D2401006
“Lead / Pull” is the deviation of the vehicle from a straight
path on a level road even with no pressure on the
steering wheel.
Lead is usually caused by the following conditions.
• Improper tire and wheel alignment.
• Uneven brake assemblies.
• Tire construction.
The way in which a tire is built can produce lead in a
vehicle. An example of this is placement of the belt. Off
center belts on radial tires can cause the tire to develop
a side force while rolling straight down the road. If one
side of the tire has a little larger diameter than the other,
the tire will tend to roll to one side. This will develop a
side force which can produce vehicle lead.
The procedure in the figure (Lead Diagnosis) should be
used to make sure that wheel alignment is not mistaken
for tire lead.
• Part of the lead diagnosis procedure is different from
the proper tire rotation pattern currently in the owner
and service manuals. If a medium to high mileage tire
is moved to the other side of the vehicle, be sure to
check that ride roughness has not developed
• Rear tires will not cause lead.
Balancing Wheels DescriptionS6RW0D2401007
There are two types of wheel and tire balance: static and
dynamic. Static balance, as shown in figure, is the equal
distribution of weight around the wheel. Wheels that are
statically unbalanced cause a bouncing action called
tramp. This condition will eventually cause uneven tire
wear.Dynamic balance, as shown in figure, is the equal
distribution of weight on each side of the wheel
centerline so that when the tire spins there is no
tendency for the assembly to move from side to side.
Wheels that are dynamically unbalanced may cause
shimmy.
Inflate tires to recommended pressure
Road test vehicle on level unrouned road in both directions
Switch front tires side to side and road test again
Lead corrected,
if roughness results, replace tiresLeads in same directionLeads reverses direction
Put tires back in original position
and check alignmentInstall a known-good tire on one front side
Lead remains install a known-good
tire in place of other front tire
Lead remains known-good tires are not goodLead corrected replace tire
Lead corrected replace tire

General Description
Steering Wheel and Column ConstructionS6RW0D6201001
This double tube type steering column has the following three important features in addition to the steering function:
• The column is energy absorbing, designed to compress in a front-end collision.
• The ignition switch and lock are mounted conveniently on this column.
• With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important that only the specified screws, bolts and nuts be used as
designated, and that they are tightened to the specified torque. When the column assembly is removed from the
vehicle, special care must be taken in handling it. Use of a steering wheel puller other than the recommended puller in
this manual or a sharp blow on the end of the steering shaft, leaning on the assembly, or dropping the assembly could
shear the plastic shear pins which maintain column length and position.
The driver air bag (inflator) module is one of the supplemental restraint (air bag) system components and is mounted
to the center of the steering wheel. During certain frontal crashes, the air bag system supplements the restraint of the
driver’s and passenger’s seat belts by deploying the air bags. The air bag (inflator) module should be handled with
care to prevent accidental deployment. When servicing, be sure to observe “Precautions on Service and Diagnosis of
Air Bag System in Section 8B”.

A/C System Relay InspectionS6RW0D7216017
NOTE
Do not use blue relay for the substitute of
white relay because internal durability of a
blue relay is different from the durability of a
white relay.

1) Disconnect negative (–) cable from battery.
2) Remove compressor relay (1) or condenser cooling
fan relay (2) from main fuse box (3).
3) Check that there is no continuity between terminal
“c” and “d”. If there is continuity, replace relay.
4) Connect battery positive (+) terminal to terminal “b”
of relay and battery negative (–) terminal to terminal
“a” of relay, and then check continuity between
terminal “c” and “d”. If there is no continuity, replace
relay.
Compressor Drive Belt Inspection and
Adjustment
S6RW0D7216018
Inspection
• Check compressor drive belt (1) for wear, crack,
deformation and cleanliness. If any defect is found,
replace the belt with new one referring to
“Compressor Drive Belt Removal and Installation”.
• Check compressor drive belt tension by measuring
how much it deflects when pushed intermediate point
between magnet clutch pulley (6) and crankshaft
pulley (3) with about 100 N (10 kg) force after rotating
crankshaft pulley 360°. If belt tension is out of
specification, adjust belt tension referring to
“Adjustment”.
Compressor drive belt tension
“a”
: 7 – 8 mm (0.28 – 0.31 in.)
NOTE
When replacing drive belt, adjust drive belt
tension to the following specifications.

New compressor drive belt tension “a”
: 6 – 7 mm (0.24 – 0.28 in.)
Adjustment
1) Loosen tension pulley nut (4).
2) Adjust belt tension by tighten or loosen tension
pulley adjusting bolt (5).
3) Tighten tension pulley nut.
4) Rotate the crankshaft pulley 360°, and then recheck
belt tension.
