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+ activates
according to the auxiliary battery
status.
Automatic Mode :
When the Engine Start/Stop button
is in the ON position with the charg-
ing connector plugged in, the func-
tion activates according to the auxil-
iary battery status to prevent
overdischarge of the auxiliary bat-
tery.Information
• The Aux. Battery Saver+ activates maximum of 20 minutes. If the Aux.
Battery Saver+ function activates
more than 10 times consecutively
when in the automatic mode, the
function will stop activating, judg-
ing that there is a problem with the
auxiliary battery. In this case, drive
the vehicle for some period of time
or if the auxiliary battery returns to
normal, the function will start acti-
vating.
• 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 devises are
used.
• If the Aux. Battery Saver+ function was activated, a message will be dis-
played on the instrument cluster
and the high voltage battery level
may have decreased.

The cooling duct cools down the
high-voltage battery. When the high-
voltage battery cooling duct is
blocked, the high-voltage battery
may be overheated and the vehicle
performance may become limited
and set a hybrid warning lamp. Do
not obstruct the cooling duct with any
other objects.
Information
Clean the cooling duct for the hybrid
battery with a dry cloth on a regular
basis.
i
(Continued)
Do not put any objects into
the cooling duct of the hybrid
battery. Doing so may cause
loss of cooling duct volume to
the hybrid battery. When the
cooling duct is blocked with
any objects, immediately con-
tact your HYUNDAI dealer.
Never place a container of liq-
uid on or near the cooling
duct. If the liquid spills, the
hybrid battery located in the
luggage compartment may be
damaged.
Secure all loads in the luggage
compartment to prevent them
from being tossed about
before driving. If a sharp or
heavy load impacts or pierces
the interior luggage compart-
ment wall, the hybrid battery
system may be damaged, dete-
riorating its performance.
Never clean the cooling duct
of the hybrid battery with a
wet cloth. If any water enters
in the cooling duct of the
hybrid battery, the hybrid bat-
tery may cause an electric
shock, serious damage, injury
or death.
The hybrid battery is com-
posed of lithium-ion polymer.
If the hybrid battery is improp-
erly handled, it is dangerous
to the environment. Also it
may cause electrical shock
and severe burns, resulting in
serious injury or death.
Do not spill liquid over the
cooling duct of the hybrid bat-
tery. Doing so is very danger-
ous. It may cause electric
shock or serious injury.
Do not cover the cooling duct
with objects.(Continued)
