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 vehicle. An
incorrect fuel filler cap can result in a
serious malfunction of the fuel system
or emission control system.
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.
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- 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- Smoking
DO NOT use matches or a lighter
and DO NOT SMOKE or leave a lit
cigarette in your vehicle while at
a gas station especially during
refueling. Automotive fuel is
highly flammable and can, when
ignited, result in fire.

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 motor driven power steering is
controlled by a power steering con-
trol unit which senses the steering
wheel torque and vehicle 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. 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 ignition
switch on. This happens as the sys-
tem performs the EPS system
diagnostics. 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 the ENGINE
START/STOP button is turned to
the 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 power
steering system will not operate
and steering effort can increase.
Take your vehicle to an authorized
Kia dealer and have the vehicle
checked as soon as possible.

travel and greater pedal pressure are
required to stop the vehicle.
Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
