2022 KIA NIRO HYBRID EV fuel

H2
HEV (HYBRID ELECTRIC VEHICLE) SYSTEM
The Kia Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the electric motor for power. The electric
motor is run by a 240V high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between the engine and the electric
motor or even both at the same time.
Fuel efficiency increases when the engine is at idle, or when the vehicle is driven by the electric motor with the HEV
battery.
The HEV battery charge must be maintained because, at times, the engine may come on even at idle to act as a gen-
erator. Charging also occurs when decelerating or by regenerative braking.

Coasting guide (if equipped)
A chime will sound and the coasting
guide indicator will blink four times to
inform the driver when to take the foot
off from the accelerator by anticipat-
ing a decelerating event* based on
the analysis of driving routes and
road conditions according to the nav-
igation system. It encourages the
driver to remove foot from accelerator
pedal and allow coasting down the
road with EV motor only. This helps
prevent unnecessary fuel consump-
tion and increases fuel efficiency.
❈Examples of a deceleration events
is going down an extended hill,
slowing down while approaching a
toll booth, and approaching
reduced speed zones.
Press the Engine Start/Stop button
and put the shift lever in P(Park). In
the User Settings Mode, select
Driving Assist, Coasting Guide, and
then On to turn on the system.
Cancel the selection of coasting
guide to turn off the system. For the
explanation of the system, press and
hold the [OK] button.

To activate the system, take the fol-
lowing procedures. Enter your desti-
nation information on the navigation
and select the driving route. Then,
satisfy the following.
- The driving speed should be
between 60 km/h (37 mph) and 160
km/h (99 mph).
❈The operating speed may vary due
to difference between instrument
cluster and navigation effected by
tire inflation level.
✽ ✽
NOTICE
Coasting guide is only a supplemen-
tal system to assist with fuel-efficient
driving. Thus, the operating condi-
tions may be different in accordance
with traffic/road conditions (i.e.
driving in a traffic jam, driving on a
slope, driving on a curve). Thus,
take the actual driving conditions
into consideration, such as distances
from the vehicles ahead/ behind,
while referring to the coasting guide
system as guidance.

H33
Refuel to prevent Hybrid battery
Damage
This message is displayed when the
fuel tank is nearly empty.
You should refill the fuel tank to pre-
vent hybrid battery damage.
Check Virtual Engine Sound
System
This message is displayed when
there is a problem with the Virtual
Engine Sound System (VESS).
In this case, have the system
inspected by an authorized Kia deal-
er.
Charging stopped. Check the
cable connection
This warning message is displayed
when charging is stopped because
the charging connector is not cor-
rectly connected to the charging inlet
In this case, separate the charging
connector and re-connect it and
check whether there is any problem
(external damage, foreign sub-
stances, etc.) with the charging con-
nector and charging inlet.

charging door is open.
(Driving with the charging door open
may result in moisture inflow or dam-
age. This message is used to prevent
such occurrences.)
DRIVING THE HYBRID/PLUG-IN HYBRID VEHICLE (CONT.)

H50
When the hybrid vehicle shuts
off
When the high voltage battery or 12-
volt battery discharges, or fuel tank is
empty, the hybrid system may not
operate.
If the Hybrid system stops operating
while the vehicle is moving, reduce
the vehicle speed gradually, pull your
vehicle off the road to a safe area,
and shift the transmission in to Park
(P) position and;
1. Turn on the hazard warning flashers.
2. Set the start button at OFF, and try
to start the Hybrid system by
applying the brake pedal and
pushing the start button.
3. If the Hybrid system will not oper-
ate, refer to "EMERGENCY
STARTING" in chapter 6.
Before you try to jump start the vehi-
cle, confirm the fuel level. If the fuel
level is low add more fuel before
attempting as emergency start.
WARNING
If submersion in water occurs:
If your vehicle was flooded and
has soaked carpeting or water
on the flooring, you should not
try to start the Hybrid system.
Never touch the high voltage
cables, connectors or package
modules, because an electrical
shock may occur causing injury
or death. High Voltage cables
are orange in color.
If this occurs. have the vehicle
towed to and inspected by an
authorized Kia dealer.
WARNING - Vehicle
Accident
Never touch electric wires or
cable. If exposed electric wires
or cables are visible inside or
outside of your vehicle, an elec-
tric shock may occur.
WARNING - Putting out
fire
Never use a small quantity of
water to put out a fire in your
vehicle. If a fire occurs, evacu-
ate the car immediately and
contact the fire department.

Introduction
2 1
Your new vehicle is designed to use
only unleaded fuel having a pump
octane number ((R+M)/2) of 87
(Research Octane Number 91) or
higher. (Do not use methanol blend-
ed fuels.)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult an
authorized Kia dealer for details.)
• Tighten the cap until it clicks one
time, otherwise the Check Engine
light will illuminate.
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol), and gasoline or gasohol con-
taining methanol (also known as
wood alcohol) are being marketed
along with or instead of leaded or
unleaded gasoline.Pursuant to EPA regulations, ethanol
may be used in your vehicle.
Do not use gasohol containing more
than 15% ethanol, and do not use
gasoline or gasohol containing any
methanol. Ethanol provides less
energy than gasoline and it attracts
water, and it is thus likely to reduce
your fuel efficiency and could lower
your MPG results.
Methanol may cause drivability prob-
lems and damage to the fuel system,
engine control system and emission
control system.
Discontinue using gasohol of any
kind if drivability problems occur.
Vehicle damage or drivability prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Gasoline or gasohol containing
methanol.
2. Leaded fuel or leaded gasohol.
3. Gasohol containing more than
15% ethanol.
WARNING - Refueling
• Do not “top off” after the noz-
zle automatically shuts off.
Attempts to force more fuel
into the tank can cause fuel
overflow onto you and the
ground, causing a risk of fire.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage, especially
in the event of an accident.
FUEL REQUIREMENTS

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. Kia recom-
mends that customers do not use
fuel with an ethanol content exceed-
ing 15 percent.
✽ ✽

NOTICE
Your New Vehicle Limited Warranty
does not cover damage to the fuel sys-
tem or any performance problems
caused by the use of “E85” fuel.
✽ ✽

NOTICE
Never use any fuel containing
methanol. Discontinue use of any
methanol containing product which
may inhibit proper drivability.
Other fuels
Using fuels that contain Silicone (Si),
MMT (Manganese, Mn), Ferrocene
(Fe), and Other metalic additives,
may cause vehicle and engine dam-
age or cause misfiring, poor acceler-
ation, engine stalling, catalyst melt-
ing, clogging, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
✽ ✽

NOTICE
Damage to the fuel system or per-
formance problem caused by the use
of these fuels may not be covered by
your New Vehicle Limited
Warranty.
Gasoline containing MMT
Some gasoline contains harmful man-
ganese-based fuel additives Such as
MMT(Methylcyclopentadienyl
Manganese Tricarbonyl). Kia does not
recommend the use of gasoline con-
taining MMT. This type of fuel can
reduce vehicle performance and affect
your emission control system. The
Malfunction Indicator Lamp on the
cluster may come on.
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.
