CAUTION:

Prolonged and repeated contact with engine oil will cause removal of natural oils from the skin,
leading to dryness, irritation and dermatitis. In addition, used engine oil contains potentially
harmful contaminants which may cause skin cancer.

Precautions should be taken when replacing engine oil to minimize the risk of your skin making
contact with used engine oil. Wear protective clothing and gloves. Wash your skin thoroughly
with soap and water, or use water-less hand cleaner to remove any used engine oil. Do not use
gasoline, thinners, or solvents.

For environmental protection used oil and used oil filter must be disposed of at designated dis-
posal sites.

ON-VEHICLE INSPECTION
1. INSPECT BATTERY (MAINTENANCE- FREE BAT-
TERY)
(a) Check the battery electrolyte level.
(1) Check the electrolyte quantity of each cell.
If the electrolyte quantity is below the recommended amount,
replace the battery.
(b) Check the battery voltage.
(1) If it has been less than 20 minutes since you
stopped driving the vehicle or since the engine was
stopped, turn the ignition switch and electrical sys-
tems (headlight, blower motor, rear defogger etc.)
to the ON position for 60 seconds. This will remove
the surface charge on the battery.
(2) Turn the ignition switch and electrical systems OFF.
(3) Using a voltmeter, measure the battery voltage be-
tween the negative (-) and positive (+) terminals of
the battery.
Standard voltage: 12.5 to 12.9 V at 20C (68F)
If the voltage is less than the specification, charge the battery.
(c) Check the indicator as shown in the illustration.
HINT:

Blue: OK

White: Charging Necessary

Red: Insufficient Water
2. INSPECT BATTERY (EXCEPT MAINTENANCE-FREE
BATTERY)
(a) Check the battery electrolyte level.
(1) Check the electrolyte quantity of each cell.
If the electrolyte quantity is below the recommended amount,
add distilled water.
