Care of battery
WARNING!
• Never expose battery to open flame or electric spark because of battery generate gas which is
flammable and explosive.
• Do not allow battery fluid to contact eyes, skin, fabrics, or painted surfaces as fluid is a corrosive
acid. Flush any contacted area with water immediately and thoroughly.
• Batteries should always be kept out of reach of children.
1) The battery is a very reliable component, but needs periodical attentions.
• Keep the battery carrier clean.
• Prevent rust formation on the terminal posts.
• Keep the electrolyte up to the upper level uniformly in all cells.
• When keeping battery on vehicle over a long period of time, follow instructions given below.
– Weekly, start the engine and run it until it reaches normal operating temperature with engine speed of 2000 to
3000 rpm. Make sure all electric switches are off before storing the vehicle.
– Recharge the battery twice a month to prevent it from discharging excessively. This is especially important
when ambient temperature is low.
The battery discharges even when it is not used, while vehicles are being stored. Battery electrolyte can
freeze and battery case can crack at cold ambient condition if battery is not properly charged.
2) Keep the battery cable connections clean.
The cable connections, particularly at the positive (+) terminal post, tend to become corroded. The product of
corrosion, or rust, on the mating faces of conductors resists the flow of current.
Clean the terminals and fittings periodically to ensure good metal-to-metal contact, and grease the connections
after each cleaning to protect them against rusting.
3) Be always in the know as to the state of charge of the battery. The simplest way to tell the state of charge is to
carry out a hydrometer test. The hydrometer is an instrument for measuring the specific gravity (S.G.) of the
battery electrolyte. The S.G. of the electrolyte is indicative of the state of charge. Refer to “Battery Inspection”.

Generator DescriptionS6RW0D1A01002
The basic charging system is the IC integral regulator charging system. The internal components are connected
electrically as shown below.
Charging System Circuit
The generator features a solid state regulator that is mounted inside the generator. All regulator components are
enclosed into a solid mold, and this unit along with the brush holder assembly is attached to the rear housing. The
regulator voltage is being controlled by ECM under some conditions while driving. Refer to “Generator Control System
Description in Section 1A” in related manual.
The generator rotor bearings contain enough grease to eliminate the need for periodic lubrication.
Two brushes carry current through the two slip rings to the field coil mounted on the rotor, and under normal conditions
will provide long period of attention-free service.
The stator windings are assembled inside a laminated core that forms part of the generator frame.
A rectifier bridge connected to the stator windings contains diodes, and electrically changes that stator AC. voltages to
a D.C. voltage which appears at the generator output terminal.

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 inflation 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 in the table, converts commonly used
inflation pressures from kPa to kgf/cm
2 and psi.
Wheels DescriptionS6RW0D2401002
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 and 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.
Lateral runout limit “a”
Aluminum wheel: 0.3 mm (0.012 in.)
Steel wheel: 0.9 mm (0.035 in.)
Radial runout limit “b”
Aluminum wheel: 0.3 mm (0.012 in.)
Steel wheel: 0.7 mm (0.028 in.)
Metric Lug Nuts and Wheel Studs
All models use metric lug nuts and wheel studs.
Metric lug nuts and wheel studs size
M12 x 1.25
If a broken stud is found, see “Front Wheel Hub, Disc,

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.
