High Voltage Battery

The High Voltage battery gradually discharges even if the vehicle is not in use. As a
result, if your vehicle is parked for an extended period of time, the battery level may
get low. Keeping your vehicle's battery level low can shorten the battery life. To
maintain the battery while the vehicle is not in use, recharge the battery at least
once every three months.
The High Voltage battery life can also be affected by ambient temperature. In
particular, when it is cold outside, the vehicle's driving range on electric power can
be reduced, and a longer battery charging time is required. In addition, parking in
extremely hot or cold environments can accelerate battery drain.
To help extend the lifespan of the battery, it is recommended that you fully charge
the battery each time prior to driving.
U.S. models
Store the vehicle in a garage to insure that the temperature of the High Voltage
battery does not drop too low.

Battery Warming System
Designed to prevent the temperature of the battery from dropping when outside
temperatures drop, thereby maintaining starting and running efficiency.
If the vehicle is plugged in when outside temperatures are low, the battery warming
system will use the power from the charging equipment to maintain the
temperature of the battery until the next time the vehicle is driven.

1High Voltage Battery
The High Voltage battery drains over time, and under
some conditions, drains faster. When the battery life
is shortened, this changes the vehicle's driving
distance.
Be careful not to let the High Voltage battery drain
too much. If the battery level becomes close to zero,
it will make it impossible to start the engine.
1Battery Warming System
If the vehicle is left unplugged in cold temperatures,
the temperature of the battery will drop, possibly
resulting in a loss of running efficiency.
If left for an extended period of time in extremely
cold temperatures, the vehicle may not start. We
recommend that you plug in your vehicle when you
are parking or storing your vehicle in cold
temperatures.
