there is no power available to drive the vehicle. Contact Roadside assistance service shown in your NISSAN Warranty Information Booklet. See "If the Li-ion battery becomes completely discharged" in the "In case of emergency" section. While the vehicle is not in use When the EV (Electric Vehicle) system is off for an extended time, the 12-volt battery may be automatically charged for a short period of time on a regular basis. The Li-ion battery warmer uses electrical power from an external source when a charger is connected to the vehicle. The Li-ion battery warmer uses electrical power from the Li-ion battery when the charger is not connected to the vehicle. CHARGING THE 12-VOLT BATTERY The 12-volt battery is charged automatically using electricity stored in the Li-ion battery. When the 12-volt battery is being charged, the charge status indicator light on the instrument panel flashes. (except when charging the Li-ion battery or the power switch is in the READY to drive position.) See "Charge status indicator light" in the "Charge" section. LI-ION BATTERY WARMER CAUTION The Li-ion battery warmer does not operate if the available Li-ion battery charge is less than approximately 30% and the charger is not connected to the vehicle. To help prevent the Li-ion battery from freezing, do not leave the vehicle in an environment if temperatures may go below -1°F (-17°C) unless the vehicle is connected to a charger. The Li-ion battery warmer helps to prevent the Li-ion battery from freezing and helps to prevent significant reductions in the Li-ion battery output when the temperature is cold. The Li-ion battery warmer automatically turns on when the Li-ion battery temperature is approximately -1°F (-17°C) or colder. The Li-ion battery warmer automatically turns off when the Li-ion battery temperture is approximately 14°F (-10°C) or higher. NOTE: • Connect the charger to the vehicle and place the power switch in the OFF position when parking the vehicle if temperatures may go below -1°F (-17°C). This provides external power to the Li-ion battery warmer when it operates and does not discharge the Li-ion battery. • The charging status indicator lights illuminate in a specific pattern when the Li-ion battery warmer operates. The charging status indicator lights use the same pattern to indicate 12-volt battery charging, Climate Ctrl. Timer operation or Remote Climate Control operation (models with navigation system). The charging status indicator lights do not change if the Li-ion battery warmer operates at the same time as the above features. See "Charge status indicator light" in the "Charging" section. While vehicle is driven The Li-ion battery charges the 12-volt battery as necessary when the power switch is in the READY to drive position or ON position. The 12-volt battery is not charged in the following conditions. • When the power switch is in ACC position. • When the power switch is in ON position and shift position is in the N (Neutal) position.
