 When the fuel filler lid is frozenand does not open after 20 seconds
at freezing temperature, slightly
tap the fuel filler lid and then
attempt to open it.
Fuel door open (Plug-in hybrid)
This message is displayed when the fuel filler lid is opened. Also means "Ready to refuel".
Check fuel door (Plug-in hybrid)
This message is displayed when the
fuel filler lid is open or an abnormal-ity has occurred.
Refuel after stopping
(Plug-in hybrid)

when a vehicle equipped with a plug-
in hybrid seal-type fuel tank is in
motion (vehicle speed is greater than0 km/h(mi/h)).
Open fuel door after disconnectingcharging cable (Plug-in hybrid)
This message is displayed when you
press fuel filler lid open button whilecharging.
This message explains that refueling
is allowed to finish charging. Fuel lid is not opened when charging
cable is connected to vehicle.

This message indicates that the
charging door is open while in driv-
ing-ready state to encourage you to
inspect and close the door.
(Driving with the charging door open
may result in moisture inflow or dam-
age. This message is used to prevent
such occurrences.)

Hybrid Battery SOC (State of Charge) Gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the “L (Low) or 0” level, the vehi-
cle automatically operates the
engine to charge the battery. However, if the Service Indicator
( ) and Malfunction Indicator
Lamp (MIL) ( ) turn on when the
SOC gauge is near the “L (Low) or 0”
level, we recommend the vehicle be
checked by an authorized Kia dealer.
✽✽
NOTICE
Never try to start the vehicle if the
fuel tank is empty. In this condition,
the engine cannot charge the high
voltage battery of the hybrid system.
If you try to start the vehicle when
the fuel is empty, the high voltage
battery will become discharged and
be damaged.

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 270V 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 for the times when the engine acts as a generator, such as when stopped at idle.
Charging also occurs when decelerating or by regenerative braking.

Hybrid system warning
light
This warning light illumi‐nates:
When there is a malfunction with the
hybrid system.
In this case, we recommend that you
have the vehicle inspected by an au‐ thorized Kia dealer.
When the warning light illuminates
while driving, or does not go OFF after
starting the vehicle, have your vehicle inspected by an authorized Kia dealer.
EV mode indicator
This indicator illuminateswhen the vehicle is driven
by the electric motor.EV
Charging cable
connection indicator
(Plug-in hybrid)
This indicator illuminates in red when the charging cable is connec‐
ted. ❈ 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.NOTICE
Coasting guide is only a supplemen‐
tal system to assist with fuel-effi‐
cient driving. Thus, the operating
conditions may be different in ac‐
cordance with traffic/road condi‐
tions (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.
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.
Shift to P to charge (Plug-in 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.
