Information
• The Aux. Battery Saver+ activatesmaximum 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, a message will be dis-
played on the instrument cluster
and the high voltage battery 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 Features →
Aux. Battery Saver+'
The Aux. Battery Saver+ function
deactivates, when the driver cancels
the system setting.
LCD Message
This message is displayed when the
Aux. Battery Saver+ function has
been completed when the vehicle is
turned ON.
However, if the LCD message pops
up frequently, we recommend that
your vehicle’s auxiliary battery or
electric/electronic components be
serviced by a HYUNDAI authorised
repairer.

Do not drop water or liquid on
to HPCU, HSG, motor and
fuses. The hybrid system com-
ponents are covered. If you
drop water or liquid on to
hybrid system compone nts, it
may result in electric shock.
This hybrid vehicle uses the
hybrid battery system inverter
and converter to generate high
voltage. High voltage in the
hybrid battery system is very
dangerous and may cause
severe burns and electric
shock. This may result in seri-
ous injury or death.
For your safety, never touch,
replace, disassemble or remove
the hybrid battery system
including components, cables
and connectors. Severe burns
or electric shock may result in
serious injury or death when
you fail to follow this warning.
When the hybrid battery sys-
tem operates, the hybrid bat-
tery system can be hot. Always
be careful because burns or
electric shock may be caused
by high voltage.

WARNING

H54
If an Accident Occurs(Continued)Using small amount of water
or fire extinguishers not
meant for electrical fires
could cause serious injury or
death from electrical shocks.
Upon witnessing any sparks,
gases, flames, or fuel leakage
of your vehicle, immediately
call emergency services or
contact a HYUNDAI autho-
rised repairer. Also, advise
them that a hybrid vehicle is
involved.

(Continued)
When the vehicle is severely
damaged, remain a safe dis-
tance of 15 meter or more
between your vehicle and other
vehicles/flammables.
If a fire occurs :
If a small scale fire occurs,
use a fire extinguisher (ABC,
BC) that is meant for electrical
fires.
If it is impossible to extin-
guish the fire in the early
stage, remain a safe distance
from the vehicle and immedi-
ately call your local fire emer-
gency responders. Also,
advise them that a hybrid
vehicle is involved.
If the fire spreads to the high
voltage battery, large amount
of water is needed to put out
the fire.
(Continued)
WARNING
For your safety, do not touch
high voltage cables, connec-
tors and package modules.
High voltage components are
orange in colour.
Exposed cables or wires may
be visible inside or outside of
the vehicle. Never touch the
wires or cables, because an
electrical shock, an injury, or a
death may occur.
Any gas or electrolyte leakage
from your vehicle is not only
poisonous but also flamma-
ble. Upon witnessing one of
those, open the windows, and
remain a safe distance from
the vehicle out of the road.
Immediately call an emergency
services or contact a HYUNDAI
authorised repairer and advise
