Maintenance
•
Use a screw driver to open the caps or cover and a flashlight to inspect the level.
• If necessary, add distilled water. The levelshould never be above the indicator.

• If the battery is fully discharged a numberof times, this may shorten its service life.Keeping the battery fully charged helpsprolong its service life.
• The service life of a battery is affected byfactors such as driving conditions and cli-mate. Extreme cold may also furtherdecrease the battery’s starting capacity.
• Because the battery’s starting capacitydecreases with time, it may be necessaryto recharge it if the vehicle is not drivenfor an extended period of time or if thevehicle is usually only driven short dis-tances.
