Simple inspection and service
CAUTION
•
Whenever battery fluid has been added,
either charge the battery or run the vehicle
for a while. It is especially important in cold
weather as the battery can freeze up and be
damaged.
•
Do not add so much fluid that the fluid in the
battery rises above the "UPPER" level line.
With the fluid above the "UPPER" level, fluid
could leak out and corrode the battery termi-
nals.
3 Checking specific gravity of battery fluid
You can determine the battery's state of charge by
checking the specific gravity of its fluid.
Use a hydrometer to measure the specific gravity of
the battery fluid. If the specific gravity is lower than
1.220 (battery fluid temperature at 20°C), the bat-
tery must be recharged.
If the battery fluid temperature is higher or lower
than 20°C, you may convert a specific gravity mea-
surement into its 20°C temperature equivalent by
Z11155
using the following formula:
S = St + 0.0007 (t – 20)
20
S : specific gravity at fluid temperature of 20°C
20
St: specific gravity measurement
t: battery fluid temperature
4 Connected condition of terminals
•
Make sure the battery cables are securely
attached to the battery terminals.
•
Clean the battery terminals if they become dirty
or corroded.

5 Cleaning the terminals
Use warm water to wash and wipe off any white
powder caused by corrosion.
If a terminal is seriously corroded, remove the bat-
tery cable and clean the terminal with a wire brush
or sandpaper.
After cleaning, apply a thin coat of grease to the ter-
minals.
