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

FUEL REQUIREMENTS
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you to use unleaded gasoline with an octane rating of RON
(Research Octane Number) 95 / AKI
(Antiknock Index) 91 or higher.
You may use unleaded gasoline with an octane rating of RON 91~94 / AKI 87~90
but it may result in slight performance
reduction of the vehicle. (Do not use methanol blended fuels.)
Except Europe
Your new Kia vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane Num‐ ber) 91 / AKI (Antiknock Index) 87 or
higher. (Do not use methanol blended
fuels.)
Your new vehicle is designed to obtain maximum performance with UNLEA‐
DED FUEL, as well as minimize exhaust
emissions and spark plug fouling.
CAUTION
NEVER USE LEADED FUEL. The useof leaded fuel is detrimental to thecatalytic converter and will damagethe engine control system’s oxygensensor and affect emission control.Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (We recom‐mend that you consult an authorizedKia dealer for details.)
WARNING
•Do not "top off" after the nozzleautomatically shuts off when re‐fueling.
•Always check that the fuel cap isinstalled securely to prevent fuelspillage in the event of an acci‐dent.
Leaded (if equipped)
For some countries, your vehicle is de‐
signed to use leaded gasoline. When you are going to use leaded gasoline,
we recommend that you ask an au‐
thorized Kia dealer whether leaded gasoline in your vehicle is available or
not.
Octane Rating of leaded gasoline is
same with unleaded one.
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol), and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or in‐ stead of leaded or unleaded gasoline.
Do not use gasohol containing more
than 10% ethanol, and do not use gas‐
oline or gasohol containing any metha‐ nol. Either of these fuels may cause
drivability problems 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 problems
may not be covered by the manufac‐ turer’s warranty if they result from the
use of:

Introduction

1. Gasohol containing more than 10%ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
CAUTION
Never use gasohol which containsmethanol. Discontinue use of anygasohol product which impairs driva‐bility.
Other fuels
Using fuels such as - Silicone (Si) contained fuel,
- MMT (Manganese, Mn) contained
fuel,
- Ferrocene (Fe) contained fuel, and
- Other metalic additives contained
fuels, may cause vehicle and engine
damage or cause plugging, misfiring,
poor acceleration, engine stalling, catalyst melting, 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 cov‐
ered by your New Vehicle Limited
Warranty.
Use of MTBE
Kia recommends avoiding fuels contain‐
ing MTBE (Methyl Tertiary Butyl Ether) over 15.0% vol. (Oxygen Content 2.7%
weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may re‐ duce vehicle performance and produce
vapor lock or hard starting.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuelsystem and any performance prob‐lems that are caused by the use offuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol. (OxygenContent 2.7% weight.)
Do not use methanol
Fuels containing methanol (wood alco‐ hol) should not be used in your vehicle.
This type of fuel can reduce vehicle
performance and damage components of the fuel system, engine control sys‐
tem and emission control system.
Fuel Additives
Kia recommends that you use unleaded
gasoline which has an octane rating of RON (Research Octane Number) 95 /
AKI (Antiknock Index) 91 or higher (for
Europe) or Octane Rating of RON (Rea‐ search Octane Number) 91 / AKI (Anti‐
knock Index) 87 or higher (except Eu‐
rope).
For customers who do not use good quality gasolines including fuel additives
regularly, and have problems starting
or the engine does not run smoothly, one bottle of additives added to the
fuel tank at every 15,000 km (For Eu‐
rope)/ 10,000 km (Except Europe). Addi‐
tives are available from your authorized
Kia dealer along with information on
how to use them. Do not mix other ad‐
ditives.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
