heating (Plug-in hybrid)
• When the coolant temperature is lower than -14 °C (57 °F), and you
turn the climate control On for heat‐
ing, the above message will be dis‐
played in the cluster. Then, the vehi‐ cle will automatically switch to HEV
mode.
• When the coolant temperature is higher than -14 °C (57 °F), or you

Your vehicle at a glance

You should refill the fuel tank to pre‐
vent hybrid battery damage.
Refill inverter coolant
This warning message illuminates when
the inverter coolant is nearly empty.
You should refill the inverter coolant.
Check brakes
This warning message illuminates when
the brake performance is low or the re‐ generative brake does not work prop‐
erly due to a failure in the brake sys‐
tem.
In this case, it may take longer for the brake pedal to operate and the braking
distance may become longer.
Stop vehicle and check brakes
This warning message is displayed
when a failure occurs in the brake sys‐ tem.
In this case, park the vehicle in a safe
location and we recommend you to tow
your vehicle to the nearest authorized Kia dealer and have the vehicle inspec‐
ted.
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 anticipating
a decelerating event* based on the analysis of driving routes and road con‐
ditions of the navigation. It encourages
the driver to remove foot from the pedal and allow coasting down the road
with EV motor only. This helps prevent
unnecessary fuel consumption and in‐ creases fuel efficiency. ❈ Example of a deceleration event is
going down an extended hill, slow‐ ing down approaching a toll booth,
and approaching reduced speed
zones.
• User settings
Press the Engine Start/Stop button
and put the shift lever in P (Park). In
the User Settings Mode, select Driv‐
ing 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.
• Operation conditions To activate the system, take the fol‐
lowing procedures. Enter your desti‐
nation information on the navigation
and select the driving route. Select the ECO mode in the Integrated Driv‐
ing Control System. Then, satisfy the
following. - The driving speed should be be‐ tween 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.
Unplug vehicle to start (Plug-in
Hybrid)
The message is displayed when you
start the engine without unplugging
the charging cable. Unplug the charging
cable, and then start the vehicle.
Remaining charge time (Plug-in
Hybrid)
The message is displayed to notify the
remaining time to fully charge the bat‐ tery.

Hybrid)
The message is displayed when the
charging connector is plugged with the
shift lever in R (Reverse), N (Neutral) or
D (Drive). Move the shift lever to P
(Park) and re-start the charging proc‐ ess.

BEFORE DRIVING
Before entering vehicle
• Be sure that all windows, outsidemirror(s), and outside lights are clean.
• Check the condition of the tires.
• Check under the vehicle for any sign of leaks.
• Be sure there are no obstacles behind you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil, engine
coolant, brake fluid, and washer fluid should be checked on a regular basis,
with the exact interval depending on
the fluid. Further details are provided in Chapter 9, Maintenance.
WARNING
Driving while distracted can result ina loss of vehicle control, that maylead to an accident, severe personalinjury, and death. The driver’s pri‐mary responsibility is in the safe andlegal operation of a vehicle, and useof any handheld devices, otherequipment, or vehicle systems which

take the driver’s eyes, attention andfocus away from the safe operationof a vehicle or which are not permis‐sible by law should never be usedduring operation of the vehicle.
Before starting
• Close and lock all doors.
• Position the seat so that all controls
are easily reached.
• Adjust the inside and outside rear‐ view mirrors.
• Be sure that all lights work.
• Check all gauges.
• Check the operation of warning lights when the engine start/stop button
switch is turned to the ON position.
• Release the parking brake and make sure the brake warning light goes
out.
For safe operation, be sure you are fa‐ miliar with your vehicle and its equip‐
ment.
WARNING
All passengers must be properly bel‐ted whenever the vehicle is moving.Refer to L

• When the coolant temperature is low:The system will be limited until en‐
gine performance becomes normal.
• When driving up a hill: The system will be limited to gain
power when driving uphill because the engine torque is restricted.
• When using manual mode: The system will be limited according
to the shift location.
• When the accelerator pedal is deeply depressed for a few seconds:
The system will be limited, judging
that the driver wants to speed up.
SPORT mode
SPORT
SPORT mode focu‐ ses on dynamic driv‐ing by automatically
controlling thesteering wheel, en‐gine and transaxlesystem.
• When the DRIVE MODE button is pressed and the SPORT mode is se‐
lected, the SPORT indicator (yellow) will illuminate. • Whenever the hybrid system is re‐
started, the Drive Mode will revert
back to ECO mode. If SPORT mode is
desired, re-select SPORT mode from
the DRIVE MODE button
• If the system is activated: - After speeding, it maintains the gear and RPM for some time even
though the accelerator pedal is not depressed.
- Up-shifting is delayed.
NOTICE
In Sport drive mode, the fuel effi‐
ciency may decrease.

Plug-in hybrid vehicle
0+')1-
The drive mode may be selected ac‐
cording to the driver’s preference or road condition.
The system resets to be in the ECO
mode, when the hybrid system is re‐
started.
If there is a problem with the instru‐ ment cluster, the drive mode will be in
ECO mode and may not change to NOR‐
MAL mode.
The mode changes whenever the DRIVE MODE button is pressed.

❈ When normal mode is selected, it is
not displayed on the cluster.
ECO mode (Active ECO)
ECO
Active ECO helps
improve fuel effi‐
ciency by control‐ling certain en‐gine and trans‐axle system op‐erating parame‐ters. Fuel effi‐ciency depends
on the driver'sdriving habit and
road condition.
• When the DRIVE MODE button is pressed and the ECO mode is selec‐
ted, the ECO indicator (green) will illu‐ minate to show that the Active ECO
is operating.
• When the Active ECO is activated, it does not turn off even though the
engine is restarted again. To turn off
the system, press the DRIVE MODE button again.
When Active ECO is activated:
• The acceleration may slightly be re‐ duced eventhough you depress the
accelerator fully.
• The air conditioner performance may be limited
• The shift pattern of the automatic transaxle may change.
• The engine noise may get louder.
The above situations are normal condi‐
tions when the active eco system is ac‐
tivated to improve fuel efficiency.
Limitation of Active ECO operation:
If the following conditions occur while Active ECO is operating, the system op‐
eration is limited even though there is
no change in the ECO indicator. • When the coolant temperature is low: The system will be limited until en‐
gine performance becomes normal.
• When driving up a hill: The system will be limited to gainpower when driving uphill because
the engine torque is restricted.
• When using manual mode: The system will be limited according
to the shift location.
