the battery. In order for your battery to perform satisfactorily, keep the following in mind:
Check the fluid level in each cell in the battery every 24 months or every 15,000

overfill.
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 (A)
The fluid level should be checked if the battery has been recharged.

Never disconnect the battery when the engine is running, for example when changing the battery.
The battery should be disconnected from the vehicle when a battery charger is used directly on the
