2015 Hyundai Sonata refuelling

FUEL REQUIREMENTS
F8
Introduction
Petrol engine
Unleaded
Your new vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 / AKI (Anti-Knock Index)
87 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.
Petrol containing ethanol
Ethanol [E-10], a mixture of petrol
and ethanol (also known as grain
alcohol), is marketed along with or
instead of leaded or unleaded petrol.
Do not use petrol containing more
than 10% ethanol, and do not use
petrol or ethanol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine con-
trol system and emission control sys-
tem.
Discontinue using ethanol of any
kind if driveability problems occur.
Vehicle damage or driveability prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Petrol containing more than 10%
ethanol.
2. Petrol or ethanol containing
methanol.
3. Leaded fuel or leaded ethanol.
•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
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental
to the catalytic converter and
will damage the engine control
system’s oxygen sensor and
affect emission control.
Never add any fuel system
cleaning agents to the fuel tank
other than what has been speci-
fied. (We recommend that you
consult an authorised HYUNDAI
dealer for details.)

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.i
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.

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.

•When refuelling, always move
the shift lever to the P (Park)
position (for automatic
transaxle) or first gear or R
(Reverse, for manual
transaxle), 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.
(Continued)
(Continued)
•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.
•Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
(Continued)
•Use only approved portable
plastic fuel containers designed
to carry and store petrol.
•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.

Information
• If the vehicle is not on level ground
or 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 regis-
ter additional fuel if less than 6 litres
(1.6 gallons) 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 from the total driving distance
and fuel consumption since the last
average fuel economy reset.
- Fuel economy range:
0.0 - 99.9 L/100km, km/L
• 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
second when the average fuel econo-
my is displayed.
Automatic reset
To adjust the average fuel economy
to reset automatically whenever refu-
elling, select the “Auto Reset” mode
in User Setting menu of the LCD dis-
play (Refer to “LCD Display”).
Under “Auto Reset” mode, the aver-
age fuel economy will be cleared to
zero (---) when the vehicle speed
exceeds 1 km/h after refuelling more
than 6 litres (1.6 gallons).
Information
The average fuel economy is not dis-
played if the vehicle has not been driv-
en for more than 10 seconds or 300
metres, since the ignition switch or the
Engine Start/Stop button was turned
on.
Instant Fuel Economy (3)
• This mode displays the instant fuel
economy during the last few sec-
onds when the vehicle speed is
more than 10 km/h.
- Fuel economy range:
0 - 30 L/100km, km/L
