CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions:
■When working on the engine compartment:
● Keep hands, clothing and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.

Maintenance and care
Battery
Check the battery as follows:
■ Battery exterior
Make sure that the battery terminals are not corroded and that
there are no loose connections, cracks, or loose clamps.
Te r m i n a l s
Hold-down clamp
■ Checking battery fluid
Check that the level is between
the “UPPER LEVEL” and
“LOWER LEVEL” lines.
“UPPER LEVEL” line
“LOWER LEVEL” line
If the fluid level is at or below the
“LOWER LEVEL” line, add dis-
tilled water.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear out or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious proble\
m.

■Adding distilled water
Remove the vent plug.
Add distilled water.
If the “UPPER LEVEL” line cannot be seen, check the fluid level by
looking directly at the cell.
Put the vent plug back on and close it securely.
Low O.K.
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable
and explosive. Therefore, observe the following before recharging:
● If recharging with the battery installed on the vehicle, be sure to discon-
nect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.
CAUTION
■Chemicals in the battery

hydrogen gas which is flammable and explosive. To reduce the risk of death
or serious injury, take the following precautions while working on or near the
battery:
●Do not cause sparks by touching the battery terminals with tools.
