If you Have a Flat Tire While
Driving
If a tire goes flat while you are driving:

[Take your foot off the accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake carefully
and pull off the road. Drive off the
road as far as possible and park on
firm, level ground. If you are on a
divided highway, do not park in the
median area between the two traffic
lanes.

[ When the vehicle is stopped, press
the hazard warning flasher button,
move the shift lever into P (Park), and
apply the parking brake, and place
the ignition switch in the LOCK/OFF
position.

[ Have all passengers get out of the
vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.

[ When changing a flat tire, follow the
instructions provided later in this
chapter.
[Be sure to shift the gear to P (Park).
The vehicle starts only when the gear
is in P (Park).

[ 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. 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
battery, but you must start vehicle
within 15 seconds of pressing the 12V
Battery Reset switch. After starting
the vehicle (
indicator ON ),
operate the vehicle safely outdoors in
ready mode stopped and/or drive it
for 30 minutes total to charge the 12V
battery fully.

[ Check the fuel level and add fuel if
necessary.

NOTICE
External power source using 12V battery
The use of external power accessories
may reduce performance and function
of the vehicle. Especially, the use of
dash cameras 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 instructions.
CAUTION
Jump starting can be dangerous if
done incorrectly. Follow the jump
starting procedure in this section to
avoid serious injury or damage to
your vehicle. If in doubt about how to
properly jump start your vehicle, we
strongly recommend that you have a
service technician or towing service do
it for you.
1. Position the vehicles close enough that the jumper cables will reach, but
do not allow the vehicles to touch.
Avoid fans or any moving parts in the
engine compartment at all times, even
when the vehicles are turned off.
2. 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.
OCN7H070001
3. Connect the jumper cables in the exact sequence shown in the
illustration. First connect one jumper
cable to the red, charging terminal
inside the engine compartment fuse
panel (1).
4. Connect the other end of the jumper cable to the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
5. Connect the second jumper cable to the black, negative (-) battery/chassis
ground of the assisting vehicle (3).
6. Connect the other end of the second jumper cable to the black, negative (-)
chassis ground of your vehicle (4).
Do not allow the jumper cables to
contact anything except the correct
battery or jumper terminals or the
correct ground. Do not lean over the
battery when making connections.

7. Press the 12V Battery Reset switch.
8. Start the engine of the assisting vehicle and let it run for a few
minutes.
9. Start your vehicle as soon as possible. After starting the vehicle
(
indicator 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 your vehicle will not start after a few
attempts, it probably requires service.
In this event please seek qualified
assistance. If the cause of your battery
discharging is not apparent, have your
vehicle checked by an authorized
HYUNDAI dealer.
Disconnect the jumper cables in the
exact reverse order you connected them:
1. Disconnect the jumper cable from the black, negative (-) chassis ground of
your vehicle (4).
2. Disconnect the other end of the jumper cable from the black, negative
(-) battery/chassis ground of the
assisting vehicle (3).
3. Disconnect the second jumper cable from the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
4. Disconnect the other end of the jumper cable from the red,
charging terminal inside the engine
compartment fuse panel (1).
Information
The voltage range of the charger should be
13.3~14V and its current range should be
less than 60A. (13.8V is recommended).
CAUTION

[The use of an improper charger
with a voltage and current range
higher than specified may cause
overheating and damage to the 12V
battery.

[ The use of an incorrect charger will
lead to a power shut-off to save the
12V battery. Stop using the incorrect
charger once the power of the
vehicle is shut off.
Information
An inappropriately disposed
battery can be harmful to
the environment and human
health. Dispose of the battery
according to your local law(s) or
regulations.
NOTICE
To prevent damage to your vehicle:

[Only use a 12-volt power supply
(battery or jumper system) to jump
start your vehicle.

[ Do not attempt to jump start your
vehicle by push-starting.
CAUTION
Do not jump start another vehicle with
your hybrid vehicle. Jump starting
another vehicle will damage the
hybrid vehicle’s 12 volt battery (lithium
polymer type).

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Shift the gear to P (Park) and set the parking brake
3. Turn off the air conditioner.
4. When the coolant or hot steams gush out of the reservoir, stop the
engine and we recommend that
you call an authorized HYUNDAI
dealer for assistance. If the coolant
does not flow out, leave the engine
compartment opened, while running
the engine. Check the coolant
temperature gauge on the instrument
cluster and turn off the engine to
make sure the coolant temperature is
sufficiently cooled down. 5. Cool down the engine sufficiently
and check the coolant level. When it
is insufficient, 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 coolant leakages,
the cooling-fan malfunction or the
water pump drive belt damages,
immediately stop the engine, and
have your vehicle checked by an
authorized HYUNDAI dealer.

[ You should mix antifreeze and water in
a proper ratio to make coolant. If the
antifreeze ratio is too high or low, it
may cause overheating due to the lack
of cooling function.
(Refer to the Mix Ratio in “Checking
the coolant level” in chapter 9.)

[ If overheating happens repeatedly,
we recommend that you have
your vehicle to be checked by an
authorized HYUNDAI dealer.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury.
IF THE ENGINE OVERHEATS

Emergency Situations8-8
WARNING
Never remove the engine
coolant cap and/or inverter
coolant cap or the drain plug
while the engine and radiator
are hot.
Hot coolant and steam may blow out
under pressure, causing serious injury.
Turn the hybrid system off and wait until
the engine cools down. Use extreme
care when removing the engine coolant
cap and/or inverter coolant cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure is
released from the cooling system. When
you are sure all the pressure has been
released, press down on the cap, using
a thick towel, and continue turning
counterclockwise to remove it.
CAUTION

[ Serious loss of coolant indicates a
leak in the cooling system and should
be checked as soon as possible by an
authorized HYUNDAI dealer.

[ When the engine overheats from
low engine coolant, suddenly adding
engine coolant may cause cracks
in the engine. To prevent damage,
add engine coolant slowly in small
quantities.
