Avoid refueling the vehicle
while charging the (high-volt-
age) hybrid battery. It may
cause a fire or an explosion due
to static electricity.
WARNING
Before refueling, be sure to
check what type of fuel is used

If you put diesel fuel into a
gasoline-powered vehicle or
gasoline into a diesel-powered
vehicle, it may affect the fuel
system and cause serious dam-
age to the vehicle.

WARNING- Cell phone
fires
Do not use cellular phones
while refueling. Electric current
and/or electronic interference
from cellular phones can poten-
tially ignite fuel vapors causing
a fire.
WARNING- Portable fuel
container
When using an approved
portable fuel container, be sure
to place the container on the
ground prior to refueling. Static
electricity discharge from the
container can ignite fuel vapors
causing a fire. Once refueling
has begun, contact with the
vehicle should be maintained
until the filling is complete. Use
only approved portable plastic
fuel containers designed to
carry and store gasoline.
Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.
WARNING- Fire/explo-
sion risk
Read and follow all warnings
posted at the gas station facili-
ty. Failure to follow all warnings
may result in severe personal
injury, severe burns or death
due to fire or explosion.
WARNING- Static
electricity
Before touching the fuel noz-
zle, you should eliminate
potentially dangerous static
electricity discharge by touch-
ing another metal part of the
vehicle, a safe distance away
from the fuel filler neck, noz-
zle, or other gas source.
Do not get back into a vehicle
once you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or
fabric (polyester, satin, nylon,
etc.) capable of producing stat-
ic electricity. Static electricity
discharge can ignite fuel
vapors resulting in rapid burn-
ing. If you must reenter the
vehicle, you should once again
eliminate potentially danger-
ous static electricity discharge
by touching a metal part of the
vehicle, away from the fuel filler
neck, nozzle or other gasoline
source.WARNING- Refueling
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap. If
pressurized fuel sprays out, it
can cover your clothes or skin
and subject you to the risk of
fire and burns.

Features of your vehicle
Make sure to refuel your vehicle
according to the “Fuel requirements”
suggested in chapter 1.
If the fuel filler cap requires replace-
ment, use only a genuine Kia cap or
the equivalent specified for your vehi-
cle. An incorrect fuel filler cap can
result in a serious malfunction of the
fuel system or emission control sys-
tem.
WARNING- Smoking
DO NOT use matches or a
lighter and DO NOT SMOKE or
leave a lit cigarette in your vehi-
cle while at a gas station espe-
cially during refueling.
Automotive fuel is highly flam-
mable and can, when ignited,
result in fire.
WARNING- Refueling &
Vehicle fires
When refueling, always shut the
engine off. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire. Once
refueling is complete, check to
make sure the filler cap and
filler door are securely closed,
before starting the engine.
WARNING
In case of using EV drive mode
for a certain time without run-
ning Engine, EMM(Engine
Maintenance Mode) will auto-
matically activate by the system
to protect fuel system and the
engine.
Therefore, even though if it is
possible to use EV drive mode
with enough battery power, the
engine may run by the system
to protect fuel system and the
engine.
If you leave the fuel without
refueling or using for over 6
months, the remained fuel in the
fuel system may be deteriorat-
ed. From this, corrosion or
blocking problem may occur.
It is recommended using mini-
mum 40% of remained fuel at
least every 6 months by select-
ing Hybrid (CS) mode and refu-
el the vehicle with new fuel.
CAUTION- Exterior paint
Do not spill fuel on the exterior
surfaces of the vehicle. Any
type of fuel spilled on painted
surfaces may damage the paint.
