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 the vehicle (
indicator on), operate the vehicle
safely outdoors in ready mode
stopped and/or drive it for 30 min-
utes total to charge the 12V bat-
tery 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.

What to do in an emergency
If your engine coolant 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. Turn ON the hazard warning flash-
er, 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 brake.
3. 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 authorized
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, while 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 authorized
HYUNDAI dealer.

7. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
8. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
Your vehicle is
equipped with a pres-
surized coolant
reserve tank. NEVER
remove the coolant
reserve tank cap or the radiator
drain plug while the engine and
radiator are HOT. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the coolant reserve tank
cap. Wrap a towel or thick rag
around it, and turn it counter-
clockwise slowly to release
some of the pressure from the
system. Step back while the
pressure is released.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.

When the tire pressure monitoring
system warning indicators are illumi-
nated and the warning message is
displayed on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The LCD posi-
tion indicator will indicate which tire
is significantly under-inflated by illu-
minating the corresponding position
light.If any of your tire pressures are indi-
cated as being low, immediately
reduce your speed, avoid hard cor-
nering, and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle's placard or tire inflation pressure
label located on the driver's side cen-
ter pillar outer panel.
