• If the vehicle will not be in use for
an extended period of time, charge
the high voltage battery once every
three months to prevent it from dis-
charging. Also, if the charge
amount is not enough, immediate-
ly charge to full and store the vehi-
cle.
• Normal charge is recommended to
keep the high voltage battery in
optimal condition.
If the high voltage battery charge
amount is below 20%, you can
keep the high voltage battery per-
formance in optimal condition if
you charge the high voltage battery
to 100%. (Once a month or more is
recommended.)
High Voltage Battery Warmer
System
The high voltage battery warmer
system prevents reduction of battery
output when battery temperature is
low. If the charging connector is con-
nected, the warmer system automat-
ically operate according to the bat-
tery temperature.
Charging time may shorten compare
to vehicles without the high voltage
battery warmer system. But, electric-
ity charge may increase because of
high voltage battery warmer system
operation.
•Make sure to use a designated
charger when charging the
high voltage battery. Using dif-
ferent types of chargers may
have a serious impact on vehi-
cle durability.
•Make sure that the high volt-
age battery charger gauge
does not reach ''L (Low) or 0".
If the vehicle is kept at ''L (Low)
or 0" for a long period, it may
damage the high voltage bat-
tery and the high voltage bat-
tery may have to be replaced
depending on the level of
degradation.
•If the vehicle is in a collision,
we recommend that you con-
tact an authorized HYUNDAI
dealer to inspect whether the
high voltage battery is still
connected.
CAUTION
The high voltage battery warmer
system operates when the charg-
ing connector is connected to
the vehicle.
However, the high voltage
warmer system may not operate
when battery temperature drops
below -35°C (-31°F).
