Diagnostic Information and Procedures
Battery InspectionS7RS0B1A04001
Common Causes of Failure
A battery is not designed to last indefinitely; however, with proper care, it will provide many years of service. If the
battery performs satisfactorily during te st but fails to operate properly for no apparent reason, the following are some
factors that may point to the cause of trouble:
• Accessories left on overnight or for an extended period without the generator operating.
• Slow average driving speeds for short periods.
• Electrical load exceeding generator output partic ularly with addition of aftermarket equipment.
• Defects in charging system such as high resistance, s lipping drive belt, loose generator output terminal, faulty
generator or voltage regulator, Refer to “Generator Symptom Diagnosis”.
• Battery abuse, including failure to keep battery cable terminals clean and tight or loose battery hold down.
• Mechanical problems in electrical sys tem such as shorted or pinched wires.
Visual Inspection
Check for obvious damage, such as cracked or broken case or cover, that could permit loss of electrolyte. If obvious
damage is noted, replace battery. Determine cause of damage and correct as needed.

emergency flat tire repair.
General Description
Tires DescriptionS7RS0B2401001
The tire is of tubeless type. The tire is designed to
operate satisfactorily with loads up to the full rated load
capacity when inflated to the recommended inflation
pressures.
Correct tire pressures and driving habits have an
important influence on tire life. Heavy cornering,
excessively rapid acceleration, and unnecessary sharp
braking increase tire wear.
Tire Placard
The “Tire Placard” is located on the left or right door lock
pillar and should be referred to tire information.
The placard lists the maximum load, tire size and cold
tire pressure where applicable.
NOTE
Whether rim size and/or maximum load are
listed or not depends on regulations of each
country.
Inflation of Tires
The pressure recommended for any model is carefully
calculated to give a satisfacto ry ride, stability, steering,
tread wear, tire life and resistance to bruises.
Tire pressure, with tires cold, (after vehicle has set for 3
hours or more, or driven less than one mile) should be
checked monthly or before any extended trip. Set to the
specifications on the “Tire Placard” located on the left
door lock pillar.
It is normal for tire pressure to increase when the tires
become hot during driving.
Do not bleed or reduce tire pressure after driving.
Bleeding reduces the “Cold Inflation Pressure”.
Higher than recommended pressure can cause:
• Hard ride
• Tire bruising or carcass damage
• Rapid tread wear at center of tire
Unequal pressure on same axle can cause:
• Uneven braking
• Steering lead
• Reduced handling
• Swerve on acceleration
Page 469 of 1496
Downloaded from www.Manualslib.com manuals search engine Wheels and Tires: 2D-2
Lower than recommended pressure can cause:
• Tire squeal on turns
• Hard Steering
• Rapid and uneven wear on the edges of the tread
• Tire rim bruises and rupture
• Tire cord breakage
• High tire temperature
• Reduced handling
• High fuel consumption
Replacement Tires
When replacement is necessary, the original equipment
type tire should be used. Refer to the Tire Placard.
Replacement tires should be of the same size, load
range and construction as those originally on the vehicle.
Use of any other size or type tire may affect ride,
handling, speedometer / odometer calibration, vehicle
ground clearance and tire or snow chain clearance to the
body and chassis.
It is recommended that new tires be installed in pairs on
the same axle. If necessary to replace only one tire, it
should be paired with the tire having the most tread, to
equalize braking traction.
WARNING!
Do not mix different types of tires on the
same vehicle such as radial, bias and bias-
belted tires except in emergencies, because
handling may be seriously affected and may
result in loss of control.
The metric term for tire infl ation pressure is the kilo
pascal (kPa). Tire pressures is usually printed in both
kPa and kgf/cm
2 on the “Tire Placard”.
Metric tire gauges are available from tool suppliers.
The chart, shown the table, converts commonly used
inflation pressures from kPa to kgf/cm
2 and psi.
Wheels DescriptionS7RS0B2401002
Wheel Maintenance
Wheel repairs that use welding, heating, or peening are
not approved. All damaged wheels should be replaced.
Replacement Wheels
Wheels must be replaced if they are bent, dented, have
excessive lateral or radial runout, air leak through welds,
have elongated bolt holes, if lug wheel bolts won’t stay
tight, or if they are heavily rusted. Wheels with greater
runout than shown in the following may cause
objectional vibrations.
Replacement wheels must be equivalent to the original
equipment wheels in load capacity, diameter, rim with
offset and mounting configuration. A wheel of improper
size or type may affect wheel and bearing life, brake
cooling, speedometer / odometer calibration, vehicle
ground clearance and tire clearance to body and
chassis.
How to Measure Wheel Runout
To measure the wheel runout, it is necessary to use an
accurate dial indicator. The tire may be on or off the
wheel. The wheel should be installed to the wheel
balancer of the like for proper measurement.
Take measurements of both lateral runout “a” and radial
runout “b” at both inside an d outside of the rim flange.
With the dial indicator set in place securely, turn the
wheel one full revolution slowly and record every reading
of the indicator.
When the measured runout exceeds the specification
and correction by the balancer adjustment is impossible,
replace the wheel. If the reading is affected by welding,
paint or scratch, it should be ignored.

Metric lug nuts and wheel studs size
M12 x 1.25
If broken stud or nut are found, be sure to replace both
stud and nut with new one.
Irregular and/or Premature Wear DescriptionS7RS0B2401003
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 DescriptionS7RS0B2401004
Original equipment tires have built-in tread wear
indicators (1) to show when they need replacement.
These indicators (1) will app ear 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 DescriptionS7RS0B2401005
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 f aulty 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 w addle 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.
