The hazard warning flasher serves as
a warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle.
It should be used whenever emer-
gency repairs are being made or
when the vehicle is stopped near the
edge of a roadway.To turn the hazard warning flasher
on or off, press the hazard warning
flasher button with the ignition switch
in any position. The button is located
in the centre fascia panel. All turn
signal lights will flash simultaneously.
• The hazard warning flasher oper-
ates whether your vehicle is run-
ning or not.
The turn signals do not work when
the hazard flasher is on.
If the engine stalls whilst driv-
ing
Reduce your speed gradually,
keeping a straight line. Move cau-
tiously off the road to a safe place.
Turn on your hazard warning flasher.
Try to start the engine again. If your
vehicle will not start, we recom-
mend that you contact an autho-
rised HYUNDAI dealer.
If the engine stalls at a cross-
road or crossing
If the engine stalls at a crossroads or
crossing, if safe to do so, move the
shift lever to the N (Neutral) position
and then push the vehicle to a safe
location.

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 reset
switch
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.

The following items may need to be
reset after the battery has been dis-
charged or the battery has been dis-
connected.
See chapter 3 or 4 for:
Power Windows
Trip Computer
Climate Control System
Clock
Audio System
Sunroof
Driver Position Memory System
External power source using 12V
battery
The use of external power acces-
sories may reduce performance
and function of the vehicle.
Especially, the use of dash cam-
eras may shut off the power of the
vehicle prior to the dash camera's
automatic shut-down.
If the power of the vehicle is shut
off, start the vehicle as explained.
(refer to "Using the 12V Battery
Reset Switch")Jump starting
In the event vehicle still does not
have a functional 12V battery (check
if interior lights will not turn on) then
you can try a jump start to the engine
compartment jumper terminals using
a 12V booster pack or jumper cables
from another vehicle's 12V battery
according to the following instruc-
tions.1. Position the vehicles close enough
that the jumper cables will reach,
but do not allow the vehicles to
touch.
2. Avoid fans or any moving parts in
the engine compartment at all
times, even when the vehicles are
turned off.
3. Turn off all electrical devices such
as radios, lights, air conditioning,
etc. Put the vehicles in P (Park)
and set the parking brake. Turn
both vehicles OFF.
NOTICE
What to do in an emergency

ous if done incorrectly. Follow
the jump starting procedure in
this section to avoid serious

Information
An inappropriately disposed
battery can be harmful to the
environment and human
health. Dispose the battery
according to your local law(s)
or regulations.
Jump starting procedure
1. Position the vehicles close enough
that the jumper cables will reach,
but do not allow the vehicles to
touch.

What to do in an emergency
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Place the shift lever in P (Park)
and set the parking brake3. Make sure that there is no hot
steam gushing out of the engine
compartment. When it is safe to
do so, open the engine compart-
ment, and check the water-pump
connector. When the water-pump
connector is disconnected, stop
the engine, re-connect the water-
pump connector, and then re-start
the engine.
4. Set the temperature and the air
flow to the maximum, and turn ON
the air conditioner.5. When the Service warning light
( ) illuminates on the instru-
ment cluster, immediately stop the
engine, and contact an authorised
HYUNDAI dealer. When the
engine warning light ( ) illumi-
nates, or when the coolant or hot
steams gush out of the engine
compartment, leave the engine
compartment opened, whilst run-
ning the engine. This is to ventilate
the engine compartment and to
cool down the engine.
6. Check the coolant temperature
gauge on the instrument cluster to
make sure the coolant temperature
is sufficiently cooled down. Check
the coolant level. When it is insuffi-
cient, check its connection with the
radiator, the heater hose, and the
water pump for any leakage. When
there is no leakage, add the
coolant. However, if the problems
persists, such as the illumination of
the warning lights, leakages, or the
cooling-fan malfunction, which may
overheat the engine, immediately
stop the engine, and have your
vehicle checked by an authorised
HYUNDAI dealer.
