Battery
09``221 Battery maintenance
Driving habits and conditions, climate, the
number of starts, etc., all affect the service life
and function of the battery. In order for your
battery to perform satisfactorily, keep the fol-
lowing in mind:
Check the fluid level in each cell in the battery
every 24 months or every 15,000
1 miles
(24,000 km), whichever is sooner.
•
Use a screw driver to open the caps or
cover and a flashlight to inspect the level.
•
If necessary, add distilled water. The level
should never be above the indicator.
•
The fluid level should be checked if the
battery has been recharged.
•
After inspection, be sure the cap over each
battery cell or the cover is securely in
place.
•
Check that the battery cables are correctly
connected and properly tightened.
•
Never disconnect the battery when the
engine is running, or when the key is in the
ignition. This could damage the vehicle's
electrical system.
•
The battery should be disconnected from
the vehicle when a battery charger is used
directly on the battery.
