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.

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

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‐
