2018 KIA RIO check engine

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. Pursuant to EPA regulations, ethanol
may be used in your vehicle.
Do not use gasohol containing more
than 15% 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,
engine control system and emission
control 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.
3. Gasohol containing more than 15 percent ethanol
FUEL REQUIREMENTS
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.

Features of your vehicle
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.
To deactivate the immobilizersystem:
Insert the ignition key into the key
cylinder and turn it to the ON position.
To activate the immobilizer sys-tem:
Turn the ignition key to the OFF posi-
tion. The immobilizer system acti-
vates automatically. Without a valid
ignition key for your vehicle, the
engine will not start.
Your Immobilizer password is a cus-
tomer unique password and should
be kept confidential. Do not leave this
number anywhere in your vehicle.
✽ ✽ NOTICE
Keep each key separately in order to
avoid a starting malfunction.
Do not put metal accessories near
the ignition switch.
Metal accessories may interrupt the
transponder signal and may prevent
the engine from being started.
If you need additional keys or lose
your keys, consult an authorized Kia
dealer.
CAUTION - Immobilizer
damage
Do not expose your immobilizersystem to moisture, static elec-tricity and rough handling. Thismay damage your immobilizer.
CAUTION - Immobilizer
alterations
Do not change, alter or adjustthe immobilizer system becauseit could cause the immobilizersystem to malfunction.

following:
partment must be correctly
installed.
bustible material must be
removed from the engine com-
partment.
2. Return the support rod to its clip to prevent it from rattling.
3. Lower the hood until it is about 30 cm (1 ft ) above the closed position
and let it drop. Make sure that it
locks into place.
4. Check that the hood has engaged properly. If the hood can be raised
slightly, it is not properly engaged.
Open it again and close it with a lit-
tle more force.
Hood open warning
(if equipped)
The warning message will appear on
the LCD display when hood is open.

completely into the hole whenever
you inspect the engine compartment.
This will prevent the hood from falling
and possibly injuring you.
WARNING- Fire risk
Do not leave gloves, rags or any
other combustible material in the
engine compartment. Doing so
may cause a heat-induced fire.

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.
CAUTION- Exterior paint
Do not spill fuel on the exteriorsurfaces 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.

Features of your vehicle
Electric power steering (EPS)
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 electric power steering is con-
trolled by the power steering control
unit which senses the steering wheel
torque and vehicle speed to com-
mand 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 continu-
ously when the vehicle is not in
motion. However, after a few min-
utes, it will return to its normal
condition.
• When you operate the steering wheel in low temperature, noise
may occur. If the temperature
rises, the noise will likely disap-
pear. This is a normal condition. (Continued)(Continued)
• When the charging system warn-
ing light comes on or the battery
voltage is low (when the alternator
or battery does not operate nor-
mally), the steering wheel may get
heavy and become difficult to con-
trol operate abnormally.
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
require increased steering effort.
Take your vehicle to an authorized
Kia dealer and have the vehicle
checked as soon as possible.
