The battery in your vehicle is located under the floor of the trunk.
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 following in mind:
Check the fluid level in each cell in the battery every 24 months or every 15,0001 miles (24,000 km), whichever is
sooner. The fluid should be at the level shown in the illustrations above (A)
2. Do not overfill.
1More frequently in warm climates.
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.
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. Route ventilation hose through opening in
floor (see page 199
)
2The level indicator inside the battery could be designed in various ways. See illustrations.
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 battery.
However, if the battery is being charged via the connecting points in the engine compartment (see page 199), the
battery must be connected.
