The hybrid system gauge indicates
whether the current driving condition is
fuel efficient or not.
• CHARGE: Shows that the energy made by the
vehicle is being converted to electrical
energy. (Regenerated energy)
• ECO: Shows that the vehicle is being driven
in an Eco-friendly manner.
• POWER:
Shows that the vehicle is exceeding
the Eco-friendly range.
According to the hybrid system gauge
area, the “EV” indicator comes on or off. - “EV” indicator ON : Vehicle is driven using the electric motor or the
gasoline engine is stopped.
- “EV” indicator OFF : Vehicle is driven using the gasoline engine.

This gauge indicates the remaining
hybrid battery power. If the SOC is
near the “L (Low)” level, the vehicle
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)” level, have the vehicle
be checked by an authorized HYUNDAI

Aux. Battery Saver+ (Plug-in
hybrid vehicle)
The Aux. Battery Saver+ is a function that
monitors the charging status of the 12 V
auxiliary battery. If the auxiliary battery
level is low, the main high voltage battery
charges the auxiliary battery.
Information
The Aux. Battery Saver+ function will
be ON when the vehicle is delivered. If
the function is not needed, you may turn
it off in the Users Settings mode on the
cluster. For more information, refer to the
following page.
Mode
• Cycle Mode:
When the vehicle is OFF with all doors,
hood and liftgate closed, the Aux. Battery
Saver+ periodically activates according
to the auxiliary battery status.
• Automatic Mode:
When the ignition switch is in the ON
position with the charging connector
plugged in, the function activates
according to the auxiliary battery status
to prevent overdischarge of the auxiliary
battery.

Information
• The Aux. Battery Saver+ activates
maximum of 20 minutes. If the Aux.
Battery Saver+ function activates
more than 10 times consecutively, in
the Automatic Mode the function will
stop activating, judging that there is
a problem with the auxiliary battery.
In this case, drive the vehicle for some
period of time. The function will start
activating if the auxiliary battery
returns to normal.
• The Aux. Battery Saver+ function
cannot prevent battery discharge if the
auxiliary battery is damaged, worn out,
used as a power supply or unauthorized
electronic devices are used.
• If the Aux. Battery Saver+ function was
activated, the high voltage battery level
may have decreased.
System Setting
