2013 Acura TL Owner's Manual - Page 581

Checking the Battery The sensor on the negative terminal monitors your vehicle's battery condition. If there is a problem with the sensor, you will see a ''CHECK BATTERY SENSOR'' message on the multiinformation display. Have the vehicle checked by your dealer. To see the battery label, remove the left side engine compartment cover (see page 542 ). Check the terminals for corrosion (a white or yellowish powder) after removing all engine compartment covers (see page 542 ). To remove corrosion, cover the terminals with a solution of baking soda and water. It will bubble up and turn brown. When this stops, wash it off with plain water. Dry off the battery with a cloth or paper towel. Coat the terminals with grease to help prevent further corrosion. If additional battery maintenance is needed, see your Acura dealer or a qualified technician. WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds. Wash your hands after handling. If you need to connect the battery to a charger, disconnect both cables to prevent damaging your vehicle's electrical system. Always disconnect the negative ( ) cable first, and reconnect it last. The battery gives off explosive hydrogen gas during normal operation. A spark or flame can cause the battery to explode with enough force to kill or seriously hurt you. Wear protective clothing and a face shield, or have a skilled technician do the battery maintenance.
