2021 KIA NIRO HYBRID EV heater

H3
PHEV (PLUG-IN ELECTRIC VEHICLE) SYSTEM
The Kia Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both a conventional hybrid electric vehi-
cle and an all-electric vehicle.
When used as a conventional hybrid electric vehicle, the HEV computer selectively operates between the engine and
the electric motor or even both at the same time.
When it is operating in the electric vehicle mode, the vehicle is driven only using the electric motor over a certain dis-
tance until the hybrid battery becomes low. The driving distance in EV mode depends on customer driving style and road
conditions. Aggressive driving maneuvers may at times temporarily enable the engine to operate for maximum power.
The hybrid battery can be fully charged by connecting a plug to an external electric power source.
The engine can be turned on based on a number of factors such as heater usage and a frequent operation of the
accelerator pedal by a driver in Charge Depleting mode.

NOTICE
• Do not use car seat cushions that
cover up the surface of the seat
and aftermarket manufactured
passenger seat heaters.
• After conducting car interior
cleaning using steam or detergent,
the seat should be dried properly.
Afterward, check for normal
operation of the PASS AIR BAG
“ ” and air bag warning lights.
• Any service related to the passen-
ger seat and the ODS must be
done at Kia service center.
• After the passenger seat has been
removed or installed for repair
purposes, check for normal opera-
tion of the PASS AIR BAG “ ”
and air bag warning lights with a
person seated or not seated in the
passenger seat.
✽ ✽
NOTICE
When the PASS AIR BAG “ ”
symbol is illuminated, the passenger
air bag system will not operate. The
passenger air bag system will oper-
ate when necessary if the symbol is
not illuminated.
✽ ✽
NOTICE
Do not modify or replace the front
passenger seat. Don't place anything
on or attach anything such as a blan-
ket, front seat cover or after market
seat heater to the front passenger
seat. This can adversely affect the
occupant detection system.
WARNING - ODS system
Riding in an improper position or
placing items on or under the
passenger seat may interfere
with the normal operation of the
ODS (Occupant Detection
System). It is important for the
driver to instruct the passenger
as to the proper seating instruc-
tions as contained in this manual.

✽NOTICE
When starting the vehicle in cold
weather using manual temperature
control, operate the system in the fol-
lowing method to improve heating.
- Turn off or lower the blower, right
after starting the engine.
- Allow the engine to warm up dur- ing this time since the air flow
from the heater is still cold.
- After a few minutes of engine warm up, turn on or set the fan to
a higher level and adjust the tem-
perature setting to hot.
Adjusting the driver and passenger
side temperature equally
• Press the “SYNC” button to adjust
the driver and passenger side tem-
perature equally.
The passenger side temperature
will be set to the same temperature
as the driver side temperature.
Turn the driver side temperature control knob. The driver and pas-
senger side temperature will be
adjusted equally. Adjusting the driver and passenger
side temperature individually
Press the “SYNC” button again to
adjust the driver and passenger
side temperature individually. The
illumination of button turns off.
Operate the driver side tempera- ture control knob to adjust the driv-
er side temperature.
Operate the passenger side tem- perature control knob to adjust the
passenger side temperature.
Temperature conversion
You can switch the temperature
mode from Centigrade to Fahrenheit
as follows:
While pressing the OFF button,
press the AUTO button for 3 seconds
or more. The display will change from
Centigrade to Fahrenheit, or from
Fahrenheit to Centigrade. If the bat-
tery has been discharged or discon-
nected, the temperature mode dis-
play will reset to Fahrenheit.

Air intake control
This is used to select the outside
(fresh) air position or recirculated air
position.
To change the air intake control posi-
tion, push the control button. Outside (fresh) air position
With the outside (fresh)air position selected, air
enters the vehicle from
outside and is heated or
cooled according to the
function selected.
Recirculated air position With the recirculated airposition selected, air
from the passenger com-
partment will be drawn
through the heating sys-
tem and heated or
cooled according to the
function selected.
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side
windows and the air within the pas-
senger compartment may become
stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in exces-
sively dry air in the passenger com-
partment.
Fan speed control
The fan speed can be set to the
desired speed by operating the fan
speed control button.
To change the fan speed, press ( )
the button for higher speed, or push
( ) the button for lower speed. To
turn the fan speed control off, press
the front blower OFF button.

Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, have the climate control air fil-
ter replaced by an authorized Kia
dealer.
✽ ✽
NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent air
conditioner filter inspections and
changes are required.
• When the air flow rate suddenly
decreases, the system should be
checked at an authorized Kia
dealer.

CAUTION - AC Repair
It is important that the correct
type and amount of oil and
refrigerant is used, otherwise
damage to the vehicle may
occur. To prevent damage, the
air conditioning system in your
vehicle should only be serviced
by trained and certified techni-
cians.

For maximum defrosting, set the
temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired
while defrosting or defogging, set
the mode to the floor-defrost posi-
tion.
Before driving, clear all snow and
ice from the windshield, rear win-
dow, outside rear view mirrors, and
all side windows.
Clear all snow and ice from the
hood and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probabili-
ty of fogging up the inside of the
windshield.Automatic climate control
system
To defog inside windshield
1. Set the fan speed to the desired
position.
2. Select desired temperature.
3. Press the defroster button ( ).
4. The outside (fresh) air position will
be selected automatically and the
air conditioning will turn on accord-
ing to the detected ambient tem-
perature.
WINDSHIELD DEFROSTING AND DEFOGGING
WARNING - Windshield
heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and the
windshield could cause the
outer surface of the windshield
to fog up, causing loss of visi-
bility. If this occurs, set the
mode selection to the posi-
tion and fan speed control to
the lower speed.

Automatic climate control system
1. Turn the ignition switch to the ON
position.
2. Press the defroster button ( ).
3. While pressing the air conditioning
button (A/C), press the air intake
control button at least 5 times with-
in 3 seconds.
The recirculation indicator blinks 3
times with 0.5 second of interval. It
indicates that the defogging logic is
canceled or returned to the pro-
grammed status.
If the battery has been discharged or
disconnected, it resets to the defog
logic status.
Auto defogging system
Auto defogging reduces the probabil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture of inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on.This indicator illuminates
when the auto defogging
system senses the mois-
ture on the inside of the
windshield and operates.
If more moisture is in the vehicle,
higher steps operate as follow. For
example if auto defogging does not
defog inside the windshield at step 1
Outside air position, it tries to defog
again at step 2 Operating the air con-
ditioning.
Step 1 : Outside air position
Step 2 : Operating the air condition-
ing
Step 3 : Blowing air flow toward the
windshield
Step 4 : Increasing air flow toward
the windshield
