What Does Regenerative
Braking Do?
It uses an electric motor when decel-
erating and when braking and trans-
forms kinetic energy to electrical
energy in order to charge the high
voltage battery.
Battery
Hybrid
- The vehicle is composed of a
high voltage battery that drives
the motor and air conditioner, and
an integrated 12V lithium ion
polymer battery with the HEV
battery that drives the lamps,
wipers, and audio system.
- The integrated 12V battery is auto-
matically charged when the vehicle
is in the ready ( ) mode.
Plug-in hybrid vehicle
- The vehicle is composed of a
high voltage battery that drives
the motor and air-conditioner,
and an auxiliary battery (12 V)
that drives the lamps, wipers, and
audio system.
- The auxiliary battery is automati-
cally charged when the vehicle is
in the ready ( ) mode.
Hybrid System Gauge
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.

CS (Charge Sustaining, Hybrid)
mode : The high-voltage (hybrid)
battery and petrol engine is used to
drive the vehicle.
Information
Even when the battery charging rate
is high and driving in electric mode is
possible, engine may turn on in some
areas to protect the system.
Infotainment system Screen

(if equipped)
Press [PHEV] on the [Home] screen
or the [All menus] screen and the
menus related to plug-in hybrid

are displayed.
For more information, please refer
to the Multimedia System Manual
that was separately supplied with
your vehicle.
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 aux-
iliary battery level is low, the main
high voltage battery charges the aux-
iliary 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, bonnet and tailgate 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 sta-
tus 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 vehi-
cle 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
unauthorised electronic devises are
used.
• If the Aux. Battery Saver+ function
was activated, the high voltage bat-
tery level may have decreased.
System Setting
The driver can activate the Aux.
Battery Saver+ function by placing
the ignition switch to the ON position
and by selecting:
'User Settings →Other → Aux.
Battery Saver+'
The Aux. Battery Saver+ function
deactivates, when the driver cancels
the system setting.
