2018 Hyundai Ioniq Hybrid Owner's Manual

Your vehicle is equipped with a cat-
alytic converter emission control
device.
To prevent damage to the catalytic
converter and to your vehicle, take
the following precautions:
• Use only UNLEADED FUEL for
gasoline engines.
• Do not operate the vehicle when
there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
• Do not misuse or abuse the
engine. Examples of misuse are
coasting with the hybrid system off
and descending steep grades in
gear with the hybrid system off.
• Do not operate the engine at high
idle speed for extended periods (5
minutes or more).
• Do not modify or tamper with any
part of the engine or emission con-
trol system. All inspections and
adjustments must be made by an
authorized HYUNDAI dealer.• Avoid driving with an extremely low
fuel level.
Running out of fuel could cause
the engine to misfire, damaging
the catalytic converter. Maintenance

PROCEDURE FOR ENTERING FORCED ENGINE ACTIVATION MODE
If the engine needs to be kept run-
ning while the vehicle is stopped to
inspect emission gas or perform
vehicle maintenance, follow below
procedure to enter forced engine
activation mode.
1. Place the shift lever in P (Park)
position with the vehicle stopped.
Engage the parking brake. Then,
follow the steps (1) to (5).
Information
Below steps from (1) to (5) must be
completed within 60 sec. If not, the
process is reset and you must start
again from step (1).(1) Turn the ignition switch to the ON
position. Vehicles equipped with
the smart key, press the Engine
Start/Stop button twice without
depressing the brake pedal.
(2) Place the shift lever in P (Park)
position and depress the acceler-
ator pedal twice.
(3) Place the shift lever in N (Neutral)
position and depress the acceler-
ator pedal twice.
(4) Place the shift lever in P (Park)
position and depress the acceler-
ator pedal twice.
(5) With the brake pedal depressed,
start the engine, and maintain
idling state.
Information
The engine remains in idle state and
the forced engine activation mode is
maintained even when the gear is
shifted to a different position.2. " " indicator on the instrument
cluster blinks when the vehicle is
in forced engine activation mode.
Check the " " indicator blinking
to ensure that the forced engine
activation mode is correctly
entered.
Information
The " " indicator continues blink-
ing until the forced engine activation
mode is cancelled. When the mode is
cancelled the " " indicator will
stop blinking.
3. To cancel the forced engine acti-
vation mode, turn the vehicle off.

When replacing tires, use the same size originally supplied with the vehicle.
Using tires of a different size can damage the related parts or not work properly.

• It is permissible to add 20 kPa (3 psi) to the standard tire pressure specification if colder temperatures are
expected soon. Tires typically lose 7 kPa (1 psi) for every 7°C (12°F) temperature drop. If extreme temperature
variations are expected, recheck your tire pressure as necessary to keep them properly inflated.
• An air pressure generally decreases, as you drive up to a high-altitude area above sea level. Thus, if you plan
to drive a high-altitude area, check the tire pressures in advance. If necessary, inflate them to a proper level
(Air inflation per altitude: +10 kPa/1 km (+2.4 psi/1 mile).

*1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
