What to do in an emergency
Hybrid vehicle
Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
This vehicle does not have a regu- lar 12V battery that needs periodic
replacement. It is lithium ion poly-
mer type integrated into the HEV
high voltage battery. The vehicle
has a 12V battery protection sys-
tem that cuts 12V battery from
vehicle draw to prevent full dis-
charge. If vehicle will not start, first
try pressing the 12V Battery Reset
switch (left side of the steering
wheel near the fuel door open
switch) to reconnect the 12V bat-
tery, but you must start vehicle
within 15 seconds of pressing the
12V Battery Reset switch. After
starting vehicle, operate the vehi-
cle safely outdoors in ready mode
stopped and/or drive it for 30 min-
utes total to charge the 12V battery
fully. Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, we
recommend that you call a HYUNDAI
authorised repairer for assistance.

Check the battery connections to be sure they are clean and tight.
Turn on the interior light. If the light dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.
Check the fuel level and add fuel if necessary.
If the vehicle still does not start, we
recommend that you call a HYUNDAI
authorised repairer for assistance. Push or pull starting the vehicle
may cause the catalytic convert-
er to overload which can lead to
damage to the emission control
system.

may cause the catalytic con-
verter to overload which can
lead to damage to the emission
control system.

What to do in an emergency
Before jump starting
This vehicle does not have a regular
12V battery that needs periodic
replacement. It is lithium ion polymer
type integrated into the HEV high
voltage battery. The vehicle has a
12V battery protection system that
cuts 12V battery from vehicle draw to
prevent full discharge.
Using the 12V battery resetswitch
1. Press the 12V Battery Reset
switch to reconnect the 12V bat-
tery.
2. Start the vehicle within 15 sec- onds of pressing the 12V Battery
Reset switch.
3. After starting vehicle ( indica- tor on), operate the vehicle safely
outdoors in ready mode stopped
and/or drive it for 30 minutes total
to charge the 12V battery fully. If you do not start the vehicle imme-
diately after pressing the 12V Battery
Reset switch, the power of 12V bat-
tery is automatically disconnected
after few seconds to save the 12V
battery from additional discharge. If
the 12V battery is disconnected prior
to starting the vehicle, press the 12V
Battery Reset switch again and then
immediately start the vehicle as
explained.
Repeated use of the 12V Battery
Reset switch without a sufficient
engine ON cycle (30 Min+) may
cause over discharge of the 12V bat-
tery, which will prevent the vehicle
from starting. If the 12V battery is
over discharged to a point that the
reset does not work, try to jump-start
the vehicle.
Information
After starting the vehicle ( indica-
tor on), the 12V battery is being
charged whether the engine is running
or not. Although there is no engine-
sound, it is unnecessary to depress the
accelerator pedal.
