Multi-Information Display HandsFreeLink™ Battery Charge Low When the battery's state of charge is low, the vehicle's battery management system triggers one of the following ''BATTERY CHARGE LOW'' messages if the ignition is on or off. Depending on how low the battery's state of charge dropped and how long it remained low, these messages may occur frequently. It may take a number of trips to sufficiently recharge the battery and the messages to no longer appear. You can receive or make phone calls from your cell phone through your vehicle's Bluetooth® HandsFreeLink® (HFL) system without touching your cell phone. IGN ON (II) － Immediately turn off all electrical devices (interior lights, air conditioning, audio, heated seats, etc.). Try not to operate other electrically operated controls such as the power windows. Driving the vehicle will recharge the battery. If the message continues to display while driving, see your dealer. 82 2011 MDX
