2019 Hyundai Ioniq Plug-in Hybrid refuelling

F6
Introduction
Petrol engine
Unleaded
For the optimal vehicle performance,
we recommend you use unleaded
petrol which has an octane rating of
RON (Research Octane Number) 95 /
AKI (Anti Knock Index) 91 or higher.
You may use unleaded petrol with an
octane rating of RON 91-94 / AKI 87-
90 but it may result in slight perform-
ance reduction of the vehicle. (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 detrimental to
the catalytic converter and will
damage the engine control sys-
tem’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 a
HYUNDAI authorised repairer for
details.)

3. Pull the fuel filler door (1) out tofully 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.

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 gas station.
Before refuelling, note the
location of the Emergency
Petrol Shut-Off, if available, at
the gas 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.

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.(Continued)

Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter.
Do not spill fuel on the exteriorsurfaces 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.

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)
(Continued)
Do not use matches or a
lighter and do not smoke or
leave a lit cigarette in your
vehicle whilst at a gas station,
especially during refuelling.
Do not over-fill or top-off your
vehicle tank, which can cause
petrol spillage.
If a fire breaks out during refu-
elling, leave the vicinity of the
vehicle, and immediately con-
tact 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 com-
pletely removing the cap.(Continued)

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.
Close the fuel filler door after
fuelling the vehicle. If you
start the vehicle with the fuel
filler door opened, the mes-
sage, "Check fuel door", illu-
minates on the LCD display.
Avoid refuelling the vehicle
whilst charging the (high-volt-
age) hybrid battery. It may
cause a fire or an explosion
due to static electricity.

Distance to empty/Average fuel economy/Instant fuel economy
Distance to Empty (1)
The distance to empty is the esti-
mated distance the vehicle can be
driven with the remaining fuel.
If the estimated distance is below 1 mi. (1 km), the trip computer will
display "----" as distance to empty.
Information
• If the vehicle is not on level groundor the battery power has been inter-
rupted, the distance to empty func-
tion may not operate correctly. • The distance to empty may differ
from the actual driving distance as
it is an estimate of the available
driving distance.
• The trip computer may not register additional fuel if less than 2 gallon (6
litres) of fuel are added to the vehicle.
• The fuel economy and distance to empty may vary significantly based
on driving conditions, driving habits,
and condition of the vehicle.
Average Fuel Economy (2)
The average fuel economy is calcu-lated by the total driving distance
and fuel consumption since the last
average fuel economy reset.
The average fuel economy can be reset both manually and automati-
cally.
Manual reset
To clear the average fuel economy
manually, press the OK button on the
steering wheel for more than 1 sec-
ond when the average fuel economy
is displayed.
Automatic reset
To automatically reset the average
fuel economy, select between "After
Ignition" or "After Refuelling" in the
User Settings mode on the LCD dis-
play.
- After Ignition: When the engine hasbeen OFF for 4 hours or longer the
average fuel economy will reset
automatically.
- After Refuelling: The average fuel economy will reset automatically
after adding 1.6 gallons (6 litres) of
fuel or more and after driving speed
exceeds 1 mph (1 km/h).
Information
The vehicle must be driven for a min-
imum of 0.19 miles (300 meters) since
the last ignition key cycle before the
average fuel economy will be recalcu-
lated.
Instant Fuel Economy (3)
This mode displays the instanta- neous fuel economy whilst driving.
