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. Anytype of fuel spilled on paintedsurfaces may damage the paint.

Features of your vehicle
Electric Power Steering
(EPS)
The power steering uses a motor to
assist you in steering the vehicle. If
the engine is off or if the power steer-
ing system becomes inoperative, the
vehicle may still be steered, but it will
require increased steering effort.
The EPS is controlled by a power
steering control unit which senses
the steering wheel torque and vehi-
cle speed to command the motor.
The steering becomes heavier as the
vehicle’s speed increases and
becomes lighter as the vehicle’s
speed decreases for optimum steer-
ing control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power
steering checked by an authorized
Kia dealer. If the Electric Power Steering
System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steering
wheel may require increased
steering effort. Take your vehicle to
an authorized Kia dealer and have
the vehicle checked as soon as
possible.
When you operate the steering
wheel in low temperature, noise
may occur. If temperature rises, the
noise will likely disappear. This is a
normal condition.
When the vehicle is stationary, and
the steering wheel is turned all the
way to the left or right continuous-
ly, the steering wheel becomes
harder to turn. The power assist is
limited to protect the motor from
overheating.
As time passes, the steering wheel
will return to its normal condition.
✽ ✽
NOTICE
The following symptoms may occur
during normal vehicle operation:
• The EPS warning light does not
illuminate.
• The steering gets heavy immedi-
ately after turning the ENGINE
START/STOP button is ON posi-
tion. This happens as the system
performs the EPS system diagnos-
tics. When the diagnostics are
completed, the steering wheel will
return to its normal condition.
• A click noise may be heard from
the EPS relay after turning the
ENGINE START/STOP button is
ON or OFF position.
• A motor noise may be heard when
the vehicle is at a stop or at a low
driving speed.
• If the Electric Power Steering
System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steer-
ing wheel may become difficult to
control or operate abnormally.
Take your vehicle to an authorized
Kia dealer and have the vehicle
checked as soon as possible.
