When the Hybrid Vehicle Shuts
Off
When the high voltage battery is dis-
charged, when the 12-volt battery is
discharged, or when the fuel tank is
empty, the hybrid system may not
operate whilst driving. When the
Hybrid system does not operate, do
the followings:
1.Gradually reduce the vehicle
speed. Pull over your vehicle off
the road in a safe area.
2. Locate the shift lever in P (Park).
3. Turn ON the hazard warning flashers.
4.Turn OFF the vehicle, and try to
start the hybrid system again,
whilst depressing the brake pedal
and turning on the ignition switch.5.When the hybrid system still does
not operate, refer to "If the 12 Volt
Battery Is Discharged" in chapter 6.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to "If the 12 Volt
Battery Is Discharged" in the chap-
ter 6. When the fuel level is low, do
not attempt to drive the vehicle only
with the battery power. The high
voltage battery may be discharged,
and the hybrid system will turn OFF.When a submersion in water
occurs:
When your vehicle is flooded in
water, a high-voltage battery
may cause shock or fires. Thus,
turn the hybrid system OFF, take
the key in your possession and
escape to a safe place. Never
attempt physical contact with
your flooded vehicle.
Immediately contact an autho-
rised HYUNDAI dealer and
advise them that a hybrid vehicle
is involved.
WARNING

Introduction
NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage.
Unleaded
Your new vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 or higher. (Do not use
methanol blended fuels)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as min-
imise exhaust emissions and spark
plug fouling.NEVER USE LEADED FUEL.
The use of leaded fuel is detrimen-
tal to the catalytic converter and
will damage the engine control
system’s oxygen sensor and
affect emission control.
Never add any fuel system clean-
ing agents to the fuel tank other
than what has been specified (We
recommend that you consult an
authorised HYUNDAI dealer for
details.)
NOTICE
NOTICE
Do not "top off" after the noz-
zle automatically shuts off
when refuelling.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.

Fuel filler door
(Hybrid vehicle)
Opening the fuel filler door
1. Turn the vehicle off.
2. Push the fuel filler door opener
button.3. Pull the fuel filler door (1) out to
fully open.
4. To remove the fuel tank cap (2),
turn it anticlockwise. You may hear
a hissing noise as the pressure
inside the tank equalizes.
5. Place the cap on the fuel filler door.
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break
the ice and release the door. Do not
pry on the door. If necessary, spray
around the door with an approved de-
icer fluid (do not use radiator anti-
freeze) or move the vehicle to a warm
place and allow the ice to melt.

Closing the fuel filler door
1. To install the fuel tank cap, turn it
clockwise until it “clicks” one time.
2. Close the fuel filler door until it is
latched securely.(Continued)When refuelling, always move
the shift lever to the P (Park)
position, set the parking
brake, and place the ignition
switch to the LOCK/OFF posi-
tion. Sparks produced by
electrical components related
to the engine can ignite fuel
vapours causing a fire.
When using an approved
portable fuel container, be sure
to place the container on the
ground prior to refuelling. Static
electricity discharge from the
container can ignite fuel
vapours causing a fire. Once
refuelling has begun, contact
between your bare hand and
the vehicle should be main-
tained until the filling is com-
plete.
Use only approved portable
plastic fuel containers designed
to carry and store petrol.
(Continued)
Petrol is highly flammable and
explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the service station.
Before refuelling, note the
location of the Emergency
Petrol Shut-Off, if available, at
the service station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.
(Continued)
WARNING
(Continued)
Do not use mobile phones
whilst refuelling. Electric cur-
rent and/or electronic interfer-
ence from mobile phones can
potentially ignite fuel vapours
and cause a fire.
Do not get back into a vehicle
once you have begun refu-
elling. You can generate a
build-up of static electricity by
touching, rubbing or sliding
against any item or fabric capa-
ble of producing static electric-
ity. Static electricity discharge
can ignite fuel vapours causing
a fire. If you must re-enter the
vehicle, you should once again
eliminate potentially danger-
ous static electricity discharge
by touching a metal part of the
vehicle, away from the fuel filler
neck, nozzle or other petrol
source, with your bare hand.

Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter.
Do not spill fuel on the exterior
surfaces of the vehicle. Any type
of fuel spilled on painted sur-
faces may damage the paint.
If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can
result in a serious malfunction
of the fuel system or emission
control system.

Do not use matches or a
lighter and do not smoke or
leave a lit cigarette in your
vehicle whilst at a service sta-
tion, especially during refu-
elling.
Do not over-fill or top-off your

it can cover your clothes or
skin and thus subject you to
the risk of fire and burns.
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap.

Add fuel into the fuel tank
within 20 minutes after open-
ing the fuel filler door. After 20
minutes, the fuel tank may
shut off, causing fuel to over-
flow. In this case, re-press the
fuel filler door opening but-
ton.
Do not leave the fuel filler
door opened for an extended
period of time. It may dis-
charge the battery.

filler door opened, the mes-
sage, "Check fuel door", illu-
minates on the LCD display.

whilst charging the (high-volt-
age) hybrid battery. It may
cause a fire or an explosion
due to static electricity.
