Hybrid Battery SOC (State of Charge) Gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the “L (Low) or 0” level, the vehi-
cle automatically operates the
engine to charge the battery. However, if the Service Indicator
( ) and Malfunction Indicator
Lamp (MIL) ( ) turn on when the
SOC gauge is near the “L (Low) or 0”
level, we recommend the vehicle be
checked by an authorized Kia dealer.
