2006 KIA Optima engine oil

3) Sub key
Similar to the master key, this key
will only function in the ignition and
the door locks, but it will not operate
the trunk and the glove box.
One side of the key has the Kia logo
and the other side has the “S”
symbol.
IMMOBILIZER SYSTEMYour vehicle is equipped with an
electronic engine immobilizer system to
reduce the risk of unauthorized vehicle
use.
Your immobilizer system is comprised
of a small transponder in the ignition
key, and antenna coil in the key cylinder
and IU (Immobilizer Unit) in the
instrument panel.
With this system, whenever you insert
your ignition key into the ignition switch
and turn it to ON, the antenna coil in the
ignition switch receives a signal from the
transponder in the ignition key and then
sends the signal to the IU (Immobilizer
Unit).
The IU (Immobilizer Unit) checks the
signal and determines whether 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 immobilizer system:
Insert the ignition key into the key
cylinder and turn it to the ON position.
To activate the immobilizer system:
Turn the ignition key to the OFF
position. The immobilizer system
activates automatically. Without a valid
ignition key for your vehicle, the engine
will not start.

CAUTION
Don’t lose your ID key or forget the
password.
Always keep your ID key in a place
where you remember and record
your password. If you don’t have
both the password and ID key,
consult your authorized Kia dealer.
✻
NOTICE
When starting the engine, do not
use the key with other immobilizer
keys around. Otherwise the engine
may not start or may stop soon
after it starts. Keep each key
separately not to have any
malfunction after you receive your
new vehicle.

MALFUNCTION
INDICATOR LIGHT
(IF EQUIPPED)The CHECK ENGINE or malfunction
indicator light is installed in your
vehicle’s instrument panel and responds
to signals from the vehicle’s On Board
Diagnostic (OBD -II) System. The OBD-
II System monitors the performance of the
vehicle’s Emission Control System
(ECS), which is designed to reduce the
amount of air pollutants in engine exhaust
to the levels required by government
regulations.
When you first start the engine, the check
engine light will illuminate briefly as a
system check to confirm that the OBD-II
System is operating properly. As the
engine starts, this light turns off.
However, if at any time the OBD-II
system detects a faulty signal or
determines that the ECS is not performing
to specification, the CHECK ENGINE
light will illuminate continuously or flash.
Continuously ON :If the CHECK ENGINE light comes ON
while driving and illuminates continuously,
a potential problem has been discovered in
the ECS or one of the exhaust system
components. Generally, the vehicle will
continue to be driveablebut it should
be checked by an Authorized Kia Dealer
as soon as possible. This condition is
unlikely to lead to engine damage unless
a decrease in vehicle power or poor
running conditions is immediately
apparent.
Flashing ON and OFF :If the CHECK ENGINE light begins to
flash ON and OFF, a more serious
problem with the ECS or exhaust system
component has been detected. If this
happens, and there is no degradation
to performance, the vehicle is still
driveable(avoid high speeds) but should
be checked by an Authorized Kia Dealer
at your earliest possible convenience. If
the flashing CHECK ENGINE light is
accompanied by a decrease in power or
poor running conditions, safely stop the
vehicle and immediately contact Kia
Roadside Assistance.
Note that the CHECK ENGINE light
will illuminate for a problem like a loose
or missing gas cap, but will not
illuminate as a result of low engine oil or
coolant, low automatic transaxle fluid or
engine overheating. The driver will be
alerted to these conditions by other
indicators on the instrument panel.
DRIVING YOUR VEHICLE
4-24
CHECK
MS-CNA-Eng 4(~39).QXD 7/25/2005 5:16 PM Page 24

DRIVING TIPS
5-4 Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.
 Do not misuse or abuse the engine.
Examples of misuse are coasting
with the ignition off and descending
steep grades in gear with the ignition
off.
 Do not operate the engine at high idle
speed for extended periods (5
minutes or more).
 Do not modify or tamper with any
part of the engine or emission control
system. All inspections and
adjustments must be made by a
qualified technician.
Failure to observe the above precautions
could result in damage to the catalytic
converter and to your vehicle and could
void your warranties.
BEFORE DRIVINGBefore entering vehicle:
 Be sure that all windows, outside
mirror(s), and outside lights are clean.
 Check the condition of the tires.
 Check under the vehicle for any sign
of leaks.
 Be sure there are no obstacles behind
you if you intend to back up.NECESSARY
INSPECTIONSFluid levels, such as engine oil, engine
coolant, brake/clutch fluid, and washer
fluid should be checked on a regular
basis, with the exact interval depending
on the fluid. Further details are provided
in Maintenance, Section 7.
BEFORE STARTING Close and lock all doors.
 Position the seat so that all controls
are easily reached.
 Adjust the inside and outside
rearview mirrors.
 Be sure that all lights work.
 Check all gauges.
 Check the operation of warning
lights when the ignition switch is
turned to the ON position.
 Release the parking brake and make
sure the brake warning light goes out.
For safe operation, be sure you are
familiar with your vehicle and its
equipment.

5-9
 If you believe you may have gottenyour brakes wet, apply them lightly
while driving until normal braking
operation returns.WINTER DRIVING We recommend that you carryemergency equipment. Some things
you might include are tire chains, a
window scraper, windshield de-icer,
a bag of sand or salt, flares, a small
shovel and jumper cables.
 Make sure you have sufficient ethylene glycol coolant in the
radiator.
 Check the battery condition and cables. Cold temperatures reduce the
capacity of any battery, so it must be
in top shape to provide enough
winter starting power.
 Make sure the engine oil viscosity is suitable for cold weather.
 Check the ignition system for loose connections and damage.  Use antifreeze-formulated windshield
washer fluid and make sure you have
sufficient fluid for your trip. (Do not
use engine coolant antifreeze.)
 Do not use the parking brake if it might freeze. This is most likely to
happen after driving in slushy or wet
conditions and temperatures drop into
the freezing range. When parking,
shift to P (Park) with automatic
transaxle, or to 1 (First) or R
(Reverse) with a manual transaxle
and block the rear wheels.
SNOW TIRESWhen snow tires are used, select the size
and construction specified on the Tire
Pressure Label. It is strongly
recommended that snow tires be used on
all four wheels, or poor handling may
result. Snow tires should not be operated
at speeds exceeding 120 km/h (75 mph).
These tires should be inflated 4 psi (28
kPa, 0.3 kg/cm
2) above the recommended pressures shown on the Tire
Specification/Pressure Label, but inflation
should never exceed the maximum cold-
tire pressure shown on the tire sidewalls.
Do not install studded tires without first
checking local, provincial and municipal
regulations for possible restrictions
against their use.
WARNING - Snow Tire
Size
Snow tires should be
equivalent in size and type to
the vehicle’s standard tires.
Otherwise, the safety and
handling of your vehicle may be
adversely affected.

ROAD WARNINGHAZARD WARNING FLASHERThe hazard warning flasher serves as a
warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle. It
should be used whenever emergency
repairs are being made or when the vehicle
is stopped near the edge of a roadway.Depress the flasher switch with the
ignition switch in any position.
All turn signal lights will flash
simultaneously.
• The hazard warning flasher will
operate whether your vehicle is
running or not.
 The turn signals do not operate when
the hazard flasher is on.
 Care must be taken when using the
hazard warning flasher while the
vehicle is being towed. Local
regulations may prohibit using it in
this manner.
OVERHEATINGIf your temperature gauge indicates
overheating, if you experience a loss of
power, or if you hear a loud knocking or
pinging noise, the engine has probably
overheated. You should follow these
procedures if you experience any of
these symptoms.
1. Turn the hazard warning flasher on,
then drive to the nearest safe location
and stop your vehicle; set the
automatic transaxle in P (Park), or
shift the manual transaxle to neutral
and apply the parking brake.
2. Make sure the air conditioner is off.
3. If coolant or steam is boiling out of
the radiator, stop the engine, then
turn the ignition switch to the ON
position. Do not restart the engine.
The radiator cooling fan will
automatically operate with the
ignition switch in the ON position. If
the cooling fan does not operate, call
an Authorized Kia Dealer for

assistance. If coolant is not boiling
out, allow the engine to idle and open
the hood to permit the engine to cool
gradually. If the temperature does not
go down with the engine idling, stop
the engine and allow sufficient time
for it to cool.
4. The coolant level should then be
checked. If the level in the reservoir
is low, look for leaks at the radiator
hoses and connections, heater hoses
and connections, radiator, and water
pump. If you find a major leak or
another problem that may have
caused the engine to overheat, do not
operate the engine until the problem
has been corrected. Call an
Authorized Kia Dealer for assistance.
If you do not find a leak or other
problem, carefully add coolant to the
reservoir.If the engine frequently overheats, have
the cooling system checked and repaired.
EMERGENCY STARTINGJUMP STARTINGJump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting
procedures on the next page. If in doubt,
we strongly recommend that you have a
competent technician or towing service
jump start your vehicle.
6-3
WARNING - Removing
Radiator Cap
Do not remove the radiator cap
when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause
serious injury.
✻
NOTICE
Use only a 12volt jumper system.
You can damage a 12volt starting
motor, ignition system, and other
electrical parts by using a 24-volt
power supply (two 12-volt batteries
in series or a 24-volt motor
generator set).
