Checking the Battery The sensor on the negative terminal monitors your vehicles 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. Check the terminals for corrosion (a white or yellowish powder). To remove it, 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 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. If the radio fuse is removed, the audio system will disable itself. The next time you turn on the radio you will see ''ENTER CODE'' in the frequency display. Use the preset buttons to enter the digit code (see page 308). Maintenance 547 2013 MDX
