Inspection
Notice
DWhen charging the battery, do not leave the inflam-
mable objects around it.
DWhen checking the electrolyte of battery, put on an
eye protector and gloves.
1. Inspect the surface of the battery and replace if any
defects were found on it.
2. Check if the specific gravity of the electrolyte is within
the specified value.
Battery capacity(Ah)
90
Battery specific gravity≥1.24
Max. tolerance between cells≥0.04
Notice
DReplace the battery if the maximum tolerance of the
electrolyte between cells is out of the specified value.
DMeasure the specific gravity in the approx. 20°Cof
ambient temperature
3. Replenish the electrolyte if necessary.

CAUTION: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless other -
wise noted.

FUEL SYSTEM SPECIFICATION
Use Only Unleaded Fuel Rated at 89
Octane or Higher
Fuel quality and additives contained in fuel have a s ig n if i-
cant effect on power output, drivability, and life of the en-
gine.
Fuel with too low an octane number can cause engine
knock.
Caution: Use of fuel with an octane number lower
than 89 may damage engine and exhaust system.
Notice:To prevent accidental use of leaded fuel, the
nozzles for leaded fuel are larger, andwill not fit the fuel
filler neck of your vehicle.
Do Not Use Methanol
Fuels containing methanol (wood alcohol) should not be
used in vehicle.This type of fuel can reduce vehicle performance and
damage components of the fuel system.
Caution: Use of methanol may damage the fuel sys -
tem.
Vehicle Fueling from Drums or Storage
Containers
For safety reasons (particularly when using noncom-
mercial fueling systems) fuel containers, pumps and
hoses must be properly earthed.
Static electricity build up can occur under certain atmo-
spheric and fuel flow conditions if unearthed hoses, par-
ticularly plastic, are fitted to the fuel-- dispensing pump.
It is therefore recommended that earthed pumps with in-
tegrally earthed hoses be used, and that storage con-
tainers be properly earthed during all noncommercial
fueling operations.
