Features of your vehicle
Hybrid battery SOC (state of
charge) gauge
Type A
Type B
5-52
This gauge indicates the remaining hy‐
brid battery power. If the SOC is near
the L (Low) or 0 level, the vehicle au‐
tomatically 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 recom‐
mend the vehicle be checked by an au‐
thorized Kia dealer.
NOTICE

fuel tank is empty. In this condition,
the engine cannot charge the high
voltage battery of the hybrid sys‐
tem. If you try to start the vehicle
when the fuel is empty, the high
voltage battery will become dis‐
charged and be damaged.
