check engine KIA Optima 2015 4.G Owner's Manual

Introduction
Your new Kia vehicle is designed to
use only unleaded fuel having a
pump octane number ((R+M)/2) of
87 (Research Octane Number 91) or
higher.
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.)Gasoline containing alcohol andmethanol
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.
Pursuant to EPA regulations, ethanol
may be used in your vehicle.
Do not use gasohol containing more
than 10% ethanol, and do not use
gasoline or gasohol containing any
methanol. Ethanol provides less
energy than gasoline and it attracts
water, and it is thus likely to reduce
your fuel efficiency and could lower
your MPG results.
Methanol may cause drivability prob-
lems and damage to the fuel system.
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.
"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. “E85” is not compati-
ble with your vehicle. Use of “E85”
may result in poor engine perform-
ance and damage to your vehicle's
engine and fuel system. Kia recom-
mends that customers do not use
fuel with an ethanol content exceed-
ing 10 percent.
✽ ✽

NOTICE
Your New Vehicle Limited
Warranty does not cover damage to
the fuel system or any performance
problems caused by the use of “E85”
fuel.
FUEL REQUIREMENTS
WARNING - Refueling
• Do not "top off" after the nozzle 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 prevent
fuel spillage in the event of an
accident.

With a smart key, you can lock or
unlock a door and even start the
engine without inserting the key.
The functions of the buttons on a
smart key are similar to the remote
keyless entry. (Refer to the "Remote
keyless entry" in this chapter.)
Smart key functions
Carrying the smart key, you may lock
and unlock the vehicle doors. Also,
you may start the engine. Refer to
the following, for more details.
Locking
Pressing the button of the front out-
side door handles with all doors
closed and any door unlocked, locks
all the doors. The hazard warning
lights will blink and the chime will
sound once to indicate that all doors
are locked. The button will only oper-
ate when the smart key is within
0.7~1 m (28~40 in.) from the outside
door handle. If you want to make
sure that a door has locked or not,
you should check the door lock but-
ton inside the vehicle or pull the out-
side door handle.

The transmitter or smart key is
designed to give you years of trou-
ble-free use, however it can mal-
function if exposed to moisture or
static electricity. If you are unsure
how to use or replace the battery,
contact an authorized Kia dealer.
Using the wrong battery can cause the transmitter or smart key to mal-
function. Be sure to use the correct
battery.
An inappropriately dis- posed battery can be harm-
ful to the environment and
human health. Dispose the
battery according to your
local law(s) or regulation.Immobilizer system
Your vehicle may be equipped with
an electronic engine immobilizer sys-
tem to reduce the risk of unautho-
rized vehicle use.
Your immobilizer system is com-
prised of a small transponder in the
ignition key and electronic devices
inside the vehicle.
With the immobilizer system, when-
ever you insert your ignition key into
the ignition switch and turn it to ON,
it checks and determines and verifies
that the ignition key is valid.
If the key is determined to be valid,
the engine will start.
If the key is determined to be invalid,
the engine will not start.
CAUTION- Transmitter
damage
Do not drop, wet or expose thekeyless entry system transmit-ter to heat or sunlight.

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.Emergency fuel filler lid release
If the fuel filler lid does not open
using the remote fuel filler lid
release, you can open it manually.
Remove the panel in the cargo area.
Pull the handle out slightly.
CAUTION- Exterior paint
Do not spill fuel on the exterior
surfaces of the vehicle. Anytype of fuel spilled on paintedsurfaces 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 - 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.
CAUTION
Do not pull the handle exces- sively, otherwise the luggagecompartment area trim orrelease handle may be damaged.

Electric power steering
Power steering uses the 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 the power steering con-
trol unit which senses the steering
wheel torque and vehicle speed to
command the motor.
The steering wheel becomes heavier
as the vehicle’s speed increases and
becomes lighter as the vehicle’s
speed decreases for better control of
the steering wheel.
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.
✽ ✽
NOTICE
The following symptoms may occur
during normal vehicle operation:
• The steering effort is increased
immediately after turning the igni-
tion switch on. This happens as the
system 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 ignition
switch is turned to the ON or
LOCK position.
• Motor noise may be heard when the vehicle is at a stop or at a low
driving speed.
• The steering effort increases if the steering wheel is rotated continuous-
ly when the vehicle is not in motion.
However, after a few minutes, it will
return to its normal conditions.
• When you operate the steering wheel in low temperature, abnor-
mal noise could occur. If tempera-
ture rises, the noise will disappear.
This is a normal condition.
If the Electric Power Steering System
does not operate normally, the warn-
ing light will illuminate on the instru-
ment cluster. The steering 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.
