WARNING
• Before refueling, be sure to check
what type of fuel is used for your
vehicle. If you put diesel fuel into
a gasoline-powered vehicle or
gasoline into a diesel-powered
vehicle, it may affect the fuel system
and cause serious damage to the
vehicle.
• Add fuel into the fuel tank within
20 minutes after opening the fuel
filler door. After 20 minutes, the fuel
tank may shut off, causing fuel to
overflow. In this case, re-press the
fuel filler door opening button.
• Do not leave the fuel filler door
opened for an extended period of
time. It may discharge the battery.
• Close the fuel filler door after fueling
the vehicle. If you start the vehicle
with the fuel filler door opened,
the message, “Check fuel door”,
illuminates on the LCD display.
• Avoid refueling the vehicle while
charging the (high-voltage) hybrid
battery. It may cause a fire or an
explosion due to static electricity.
Closing the fuel filler door
1. To install the cap, turn it clockwise
until it “clicks” once. This indicates
that the cap is securely tightened.
2. Close the fuel filler lid and push it in lightly making sure that it is securely
closed.
WARNING
Automotive fuel 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 gas station.
• Before refueling, note the location
of the Emergency Fuel Shut-Off, if
available, at the gas station.
• Before touching the fuel nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.
• Do not use mobile phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire.
• Do not get back into a vehicle
once you have begun refueling.
You can generate a buildup of
static electricity by touching,
rubbing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapors
causing a fire. If you must re-enter
the vehicle, you should once again
eliminate potentially dangerous
static electricity discharge by
touching a metal part of the vehicle,
away from the fuel filler neck, nozzle
or other fuel source, with your bare
hand.

Convenience Features5-82
• When using an approved portable
fuel container, be sure to place the
container on the ground prior to
refueling. Static electricity discharge
from the container can ignite fuel
vapors causing a fire.
Once refueling has begun, contact
between your bare hand and the
vehicle should be maintained until
the filling is complete.
• Use only approved portable plastic
fuel containers designed to carry and
store fuel.
• When refueling, always shift the
gear to the P (Park) position, set
the parking brake, and press the
Engine Start/Stop button to the
OFF position. Sparks produced by
electrical components related to the
engine can ignite fuel vapors causing
a fire.
• Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle while at a gas station,
especially during refueling.
• Do not over-fill or top-off your
vehicle tank, which can cause fuel
spillage.
• If a fire breaks out during refueling,
leave the vicinity of the vehicle, and
immediately contact the manager
of the gas station and then contact
the local fire department. Follow any
safety instructions they provide.
• If pressurized fuel sprays out, 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 completely removing the cap.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident. Information
Make sure to refuel your vehicle according
to the “Fuel Requirements” section in
suggested in chapter 1.
NOTICE
• Do not spill fuel on the exterior
surfaces of the vehicle. Any type of
fuel spilled on painted surfaces 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.
WARNING
In case of using EV drive mode for a
certain time without running engine,
EMM (Engine Maintenance Mode) will
automatically activate by the system to
protect the fuel system and the engine.
Therefore, even though if it is possible
to use EV drive mode with enough
battery power, the engine may run by
the system to protect fuel system and
the engine. If you leave the fuel without
refueling or using for over 6 months, the
remained fuel in the fuel system may
be deteriorated. From this, corrosion
or blocking problem may occur. It is
recommended using minimum 40 % of
remained fuel at least every 6 months
by selecting Hybrid (CS)mode and
refuel the vehicle with new fuel.
