Quick Reference Guide
High Voltage Battery
The High Voltage battery gradually discharges when the vehicle is not in use. If allowed to discharge too much, the battery may become 
damaged.
If your vehicle is parked for an extended period of time, du ring storage for example, periodically recharge the battery to main tain sufficient 
charge levels. At least once every three months, recharge the High Voltage battery.
Excessive heat can also damage the batter y. On hot, sunny days, try to avoid parking your vehicle under direct sunlight.
If the High Voltage battery becomes fully discharged or damaged  and you are unable to start the power system as a result, consult an 
authorized Honda Clarity Electric dealer.
Temperature
When storing the vehicle, make sure not to expose it to extrem ely low temperatures: If the temperature of the High Voltage batt ery drops 
to –22°F (–30°C) or below, the power system  may not start. Wait for the High Voltage batt ery to warm up, or warm it up by plugging in the 
vehicle.
If the temperature of the High Voltage battery drops to –31°F (– 35°C) or below, the power system will not start. Wait for the High Voltage 
battery to warm up or move the vehicle to a warmer location. Note plugging the vehicle in will not help in this case.
