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.

ator. • Even if the smart key is in the ve‐ hicle, if it is far away from you, the engine may not start. • When the engine start/stop but‐
ton is in the ACC or ON position, if
any door is open, the system
checks for the smart key. If the
smart key is not in the vehicle,
the warning, "Key is not in vehi‐
cle" will come on, and if all doors
are closed, the chime will also
sound for about 5 seconds. The
indicator will turn off while the

gine is on.
If the starting procedure is followed,the "READY" symbol on the instrumentcluster will turn on. For more details,please refer to L

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
