Introduction
Your new vehicle is designed to use
only unleaded fuel having a pump
octane number ((R+M)/2) of 87
(Research Octane Number 91) or
higher. (Do not use methanol blend-
ed fuels.)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult an
authorized Kia dealer for details.)
Tighten the cap until it clicks onetime, otherwise the Check Engine light will illuminate.Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol), and gasoline or gasohol con-
taining methanol (also known as
wood alcohol) are being marketed
along with or instead of leaded or
unleaded gasoline.
Do not use gasohol containing more
than 15% ethanol, and do not use
gasoline or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine con-
trol system and emission control sys-
tem.
Discontinue using gasohol of any
kind if drivability problems occur.
Vehicle damage or drivability prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Gasoline or gasohol containing methanol.
2. Leaded fuel or leaded gasohol.
3. Gasohol containing more than 15% ethanol.
WARNING - Refueling
• Do not "top off" after the noz- zle automatically shuts off.
Attempts to force more fuel
into the tank can cause fuel
overflow onto you and the
ground causing a risk of fire.
Always check that the fuel cap is installed securely to pre-
vent fuel spillage, especially
in the event of an accident.

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- Cell phonefires
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 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

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 electric power steering is con-
trolled by a power steering control
unit which senses the steering wheel
torque and vehicle speed to com-
mand the motor.
The steering becomes heavier as the
vehicle's speed increases and
becomes lighter as the vehicle's
speed decreases for improved 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 position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics are complet-
ed, the steering system 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. (Continued)
