Engine coolant temperature gauge
This gauge shows the temperature of the
engine coolant when the engine
start/stop button is ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in section 6.
State of charge (SOC)
The state of charge (SOC) gauge indi-
cates the hybrid battery's charge level. If
the SOC is near L level, the vehicle auto-
matically operates the engine to charge
the battery. However, if the service indi-
cator and MIL(Malfunction indicator
lamp) turn on when the State of
Charge(SOC) is near L(Low), the vehicle
should be towed. Refer to the chapter 6.

the normal range area toward the
“H” position, it indicates overheat-
ing that may damage the engine.
