Battery – maintenance
Proper battery maintenance can help prolong its service life.
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.
• The fluid level should be checked if the bat-tery has been recharged.
• After inspection, be sure the cap over eachbattery cell or the cover is securely in place.
• Check that the battery cables are correctlyconnected and properly tightened.
• Never disconnect the battery when theengine is running, or when the key is in theignition. This could damage the vehicle'selectrical system.
• The battery should be disconnected from thevehicle when a battery charger is useddirectly on the battery.
• To help keep the battery in good condition,the vehicle should be driven for at least 15minutes a week or connected to a chargerwith an automatic charging function.
• If the battery is fully discharged a number oftimes, this may shorten its service life. Keep-ing the battery fully charged helps prolong itsservice life.
