2018 Hyundai Ioniq Plug-in Hybrid oil

F10
Introduction
This vehicle is equipped with an
event data recorder (EDR). The
main purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an
air bag deployment or hitting a
road obstacle, data that will assist
in understanding how a vehicle’s
systems performed. The EDR is
designed to record data related to
vehicle dynamics and safety sys-
tems for a short period of time,
typically 30 seconds or less. The
EDR in this vehicle is designed to
record such data as:
vehicle were operating;
passenger safety belts were
buckled/fastened;
depressing the accelerator
and/or brake pedal; and,
ing. These data can help provide a bet-
ter understanding of the circum-
stances in which crashes and
injuries occur. NOTE: EDR data
are recorded by your vehicle only
if a non-trivial crash situation
occurs; no data are recorded by
the EDR under normal driving
conditions and no personal data
(e.g., name, gender, age, and
crash location) are recorded.
However, other parties, such as
law enforcement, could combine
the EDR data with the type of per-
sonally identifying data routinely
acquired during a crash investiga-
tion.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such
as law enforcement, that have the
special equipment, can read the
information if they have access to
the vehicle or the EDR.

Malfunction IndicatorLamp (MIL)
This warning light illuminates:
When you place the Engine Start/
Stop button to the ON position.
- It illuminates for approximately 3seconds and then goes off.
When there is a malfunction with the emission control system.
In this case, have the vehicle inspect-
ed by an authorized HYUNDAI deal-
er.
Driving with the Malfunction
Indicator Lamp (MIL) on may
cause damage to the emission
control system which could affect
drivability and/or fuel economy. If the Malfunction Indicator Lamp
(MIL) illuminates, potential catalyt-
ic converter damage is possible
which could result in loss of
engine power.
In this case, have the vehicle inspect-
ed by an authorized HYUNDAI dealer
as soon as possible.
Charging System
Warning Light
When this warning light illuminates
while running the engine, the battery
is not being charged. Immediately
turn OFF all electrical accessories.
Try not to use electrically operated
controls, such as the power win-
dows. Keep running the engine.
Have the vehicle inspected by an
authorized HYUNDAI dealer as soon
as possible.
Engine Oil PressureWarning Light
This warning light illuminates:
When the engine oil pressure is low.
If the engine oil pressure is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. Turn the engine off and check the engine oil level (For more details,
refer to "Engine Oil" in chapter 7) .
If the level is low, add oil as required.
If the warning light remains on
after adding oil or if oil is not avail-
able, have the vehicle inspected
by an authorized HYUNDAI dealer
as soon as possible.

Convenient features of your vehicle
If the engine does not stopimmediately after the Engine Oil
Pressure Warning Light is illumi-
nated, severe damage could
result.
If the warning light stays on while the engine is running, it
indicates that there may be seri-
ous engine damage or malfunc-
tion. In this case:
1. Stop the vehicle as soon as it is safe to do so.
2. Turn off the engine and check the oil level. If the oil level is
low, fill the engine oil to the
proper level.
3. Start the engine again. If the warning light stays on after the
engine is started, turn the
engine off immediately. In this
case, have the vehicle inspect-
ed by an authorized HYUNDAI
dealer.
Low Fuel LevelWarning Light
This warning light illuminates:
When the fuel tank is nearly empty.
Add fuel as soon as possible.
Driving with the Low Fuel Level
warning light on or with the fuel
level below "E" can cause the
engine to misfire and damage the
catalytic converter (if equipped).
Engine Coolant Temperature WarningLight
This warning light illuminates:
When the engine coolant temper-
ature is above 248°F (120°C). This
means that the engine is overheat-
ed and may be damaged.
If your vehicle is overheated, refer
to "Overheating" in chapter 6.

Air conditioning system operation
tips
If the vehicle has been parked indirect sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
After sufficient cooling has been achieved, switch back from the
recirculated air to the fresh outside
air position.
To help reduce moisture inside of the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the win-
dows and sunroof closed.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
If you operate air conditioner excessively, the difference between
the temperature of the outside air
and that of the windshield could
cause the outer surface of the
windshield to fog up, causing loss
of visibility. In this case, set the
mode selection knob or button to
the position and fan speed
control to the lower speed.
System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through the
heating and air conditioning system.
Have the climate control air filter be
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the vehicle is being driv-
en in severe conditions such as dusty
or rough roads, more frequent air
conditioner filter inspections and
changes are required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur.

Air conditioning refrigerant label
The actual Air Conditioning refriger-
ant label in the vehicle may differ
from the illustration.
Each symbols and specification on
air conditioning refrigerant label
means as below :
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri- cant
Refer to chapter 8 for more detail
location of the air conditioning refrig-
erant label.
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used, oth-
erwise damage to the vehicle
and personal injury may occur.
