2020 Hyundai Ioniq Plug-in Hybrid fuel type

F8
Introduction
"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. "E85" is not compati-
ble with your vehicle. Use of "E85"
may result in poor engine perform-
ance and damage to your vehicle's
engine and fuel system. HYUNDAI
recommends that customers do not
use fuel with an ethanol content
exceeding 15 percent.
To prevent damage to your vehicle’s
engine and fuel system:
Never use gasohol which con-
tains methanol.
Never use gasohol containing
more than 15% ethanol.
Never use leaded fuel or leaded
gasohol.
Never use "E85" fuel.
Your New Vehicle Limited
Warranty does not cover damage
to the fuel system or any perform-
ance problems caused by the use
of "E85" fuel.
Using Fuel Additives (except
Detergent Fuel Additives)
Using fuel additives such as:
- Silicone fuel additive
- Ferrocene (iron-based) fuel additive
- Other metallic-based fuel additives
may result in cylinder misfire, poor
acceleration, engine stalling, dam-
age to the catalyst, or abnormal cor-
rosion, and may cause damage to
the engine resulting in a reduction in
the overall life of the powertrain.
- The Malfunction Indicator Lamp
(MIL) may illuminate.
Damage to the fuel system or per-
formance problem caused by the
use of these fuels or fuel additives
may not be covered by your New
Vehicle Limited Warranty.
Gasoline containing MMT
Some gasoline contains harmful
manganese-based fuel additives
such as
MMT (Methylcyclopentadienyl
Manganese Tricarbonyl
).
HYUNDAI does not recommend the
use of gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emis-
sion control system.
The malfunction indicator lamp on
the cluster may come on.
Detergent Fuel Additives
HYUNDAI recommends that you use
good quality gasolines treated with
detergent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance performance
of the Emission Control System. For
more information on TOP TIER
Detergent Gasoline, please go to the
website (www
.toptiergas.com).

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.
NOTICE

(Continued)
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
gasoline spillage.
If a fire breaks out during refu-
eling, 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)
(Continued)
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
(Continued)
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 gasoline.
When refueling, always move
the shift lever to the P (Park)
position, set the parking
brake, and place 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.

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
gasoline engine is stopped.
- "EV" indicator OFF : Vehicle is
driven using the gasoline 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.
Battery State of Charge (SOC)
gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "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 "L (Low)" level, have the
vehicle be checked by an authorized
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.
