Clean the battery with a solution of baking soda and water.
NOTE:
Care should be taken to avoid situations that can lead to potential battery discharge and potential no-start conditions such as: 1. Installation or extended use of electronic accessories that consume battery power when the engine is not running (Phone chargers, GPS, DVD players, etc.).
2. Vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to be charged to maintain battery health.
WARNING
Explosive gases can cause blindness or injury. Do not allow battery fluid to contact your skin, eyes, fabrics or painted surfaces. Sulfuric acid can cause blindness or injury. After touching a battery or battery cap, do not touch or rub your eyes. Thoroughly wash your hands. If the acid contacts your eyes, skin or clothing, immediately flush with water for at least 15 minutes and seek medical attention.
Wash hands after handling.

1. Remove the vent caps with a screwdriver as shown. Use a cloth to protect the battery case.

2. Check the fluid level in each cell. If it is necessary to add fluid, add only distilled water to bring the level up to the bottom of the filler opening. Do not overfill. Reinstall the vent caps.
Vehicles operated in high temperatures or under severe conditions require frequent checks of the battery fluid level.
Jump starting
If jump starting is necessary, refer to "Jump starting" in the "In case of emergency" section of this manual. If the engine does not start by jump starting, the battery may have to be replaced. It is recommended that you visit a NISSAN dealer for this service.
