2020 Hyundai Ioniq Hybrid fuel type

H32
What Does Regenerative
Braking Do?
It uses an electric motor when decel-
erating and when braking and trans-
forms kinetic energy to electrical
energy in order to charge the high
voltage battery.
Battery
Hybrid
- The vehicle is composed of a
high voltage battery that drives
the motor and air conditioner, and
an integrated 12V lithium ion
polymer battery with the HEV
battery that drives the lamps,
wipers, and audio system.
- The integrated 12V battery is auto-
matically charged when the vehicle
is in the ready ( ) mode.
Plug-in hybrid vehicle
- The vehicle is composed of a
high voltage battery that drives
the motor and air-conditioner,
and an auxiliary battery (12 V)
that drives the lamps, wipers, and
audio system.
- The auxiliary battery is automati-
cally charged when the vehicle is
in the ready ( ) mode.
Hybrid System Gauge
The hybrid system gauge indicates
whether the current driving condition
is fuel efficient or not.
CHARGE :
Shows that the energy made by
the vehicle is being converted
to electrical energy. (Regenerated
energy)
ECO :
Shows that the vehicle is being
driven in an Eco-friendly manner.
POWER :
Shows that the vehicle is exceeding
the Eco-friendly range.

Use of MTBE
HYUNDAI recommends avoiding
fuels containing MTBE (Methyl
Tertiary Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight) in
your vehicle.
Fuel containing MTBE over 15.0%
vol. (Oxygen Content 2.7% weight)
may reduce vehicle performance and
produce vapour lock or hard starting.
Your New Vehicle Limited
Warranty may not cover damage
to the fuel system and any per-
formance problems that are
caused by the use of fuels con-
taining methanol or fuels contain-
ing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen
Content 2.7% weight.)
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle.This type of fuel can reduce
vehicle performance and damage
components of the fuel system, engine
control system and emission control
system.
Fuel Additives
HYUNDAI recommends that you use
unleaded petrol which has an
Octane Rating of RON (Research
Octane Number) 91 or higher.
For customers who do not use good
quality petrols, and have problems
starting or the engine does not run
smoothly, one bottle of additive added
to the fuel tank is recommended
according to the maintenance sched-
ule (refer to chapter 7, “Normal
Maintenance Schedule”).
Additives are available from your
authorised HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.

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
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 service
station and then contact the
local fire department. Follow
any safety instructions they
provide.
If pressurised 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.

Power gauge
The power gauge indicates whether
the current driving condition is fuel
efficient or not.
CHARGE :
Shows that the energy made by the
vehicle is being converted to elec-
trical energy. (Regenerated energy) ECO :
Shows that the vehicle is being
driven in an Eco-friendly manner.
POWER :
Shows that the vehicle is exceed-
ing the Eco-friendly range.
Information
Accordance to the power gauge area
the “EV” indicator comes on or off.
- “EV” indicator ON : Vehicle is driv-
en using the electric motor or the
petrol engine is stopped.
- “EV” indicator OFF : Vehicle is
driven using the petrol engine.
Fuel gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.

Information
• The fuel tank capacity is given in
chapter 8.
• The fuel gauge is supplemented by a
low fuel warning light, which will
illuminate when the fuel tank is
nearly empty.
• On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier
than usual due to the movement of
fuel in the tank.
Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire
damaging the catalytic converter.
Hybrid battery SOC
(State of Charge) gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "0 or L (Low)" level, the
vehicle automatically operates the
engine to charge the battery.However, if the Service Indicator
( ) and Malfunction Indicator
Lamp (MIL) ( ) turn on when the
SOC gauge is near the "0 or L (Low)"
level, we recommend the vehicle be
checked by an authorised HYUNDAI
dealer.
❈The actual cluster in the vehicle
may differ from the illustration.
Never try to start the vehicle if the
fuel tank is empty. In this condi-
tion, the engine cannot charge the
high voltage battery of the hybrid
system. If you try to start the vehi-
cle when the fuel is empty, the
high voltage battery will become
discharged and be damaged.
NOTICE
NOTICE
i
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addi-
tional fuel as soon as possible
after the warning light comes
on or when the gauge indicator
comes close to the "0 or E
(Empty)" level.

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 register
additional fuel if less than 6 litres
(1.5 gallon) 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.
