2006 KIA Optima engine oil

7-21
BODY LUBRICATIONAll moving points of the body, such as
doors, hood hinges and locks, should be
lubricated each time the engine oil is
changed.
Use a non-freezing lubricant on locks
during cold weather.
Make sure the engine hood secondary
latch keeps the hood from opening when
the primary latch is released.
AIR CLEANERELEMENT REPLACEMENTA paper air cleaner filter is used. It must
be replaced when necessary, and should
not be cleaned and reused.
1. Remove the four (4) air cleaner cover
attaching clips.
2. Wipe the inside of the air cleaner
housing with a clean, damp cloth.
3. Replace the air cleaner element.

WARNING
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
Radiator coolant can severely
obscure visibility when
sprayed on the windshield
and may cause loss of
vehicle control or damage to
paint and body trim.
Windshield washer fluid
agents contain some
amounts of alcohol and can
be flammable under certain
circumstances. Do not allow
sparks or flame to contact
the washer fluid or the
washer fluid reservoir.
Damage to the vehicle or it's
occupants could occur.
Windshield washer fluid is
poisonous to humans and
animals. Do not drink and
avoid contacting windshield
washer fluid. Serious injury
or death could occur.

TIRES AND WHEELSTIRE CAREFor proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within the
load limits and weight distribution
recommended for your vehicle.INFLATION PRESSURESCheck all tire pressures (including the
spare) monthly when the tires are cold.
“Cold tires” means the car has not been
driven for at least three hours or driven
less than one mile (1.6 km).
Recommended pressures must be
maintained to ensure ride quality, vehicle
handling, and minimum tire wear.
Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gasing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 120°F (49°C).
Wear eye protection when
checking the battery during
charging.
Disconnect the battery
charger in the following
order.
1. Turn off the battery
charger main switch.
2. Unhook the negative
clamp from the negative
battery terminal.
3. Unhook the positive clamp
from the positive battery
terminal.
✻
NOTICE
• Before performing battery
maintenance or recharging, turn
OFF all accessories and stop the
engine.
• When remounted battery,
disconnect the negative (-)
battery cable first. When re-
installing the battery, reconnect
the negative (-) battery cable
last.

REPLACEMENT (IF EQUIPPED)1. Remove the trunk room lamp cover
using flat blade screw driver.
2. After replacement of bulb, install the
cover.
LUBRICANT
SPECIFICATIONSRECOMMENDED
LUBRICANTSTo help achieve proper engine and
powertrain performance and durability,
use only lubricants of the proper quality.
The correct lubricants also help promote
engine efficiency which results in
improved fuel economy.
Engine oils labeled Energy Conserving
Oil are now available. Along with other
additional benefits, they contribute to
fuel economy by reducing the amount of
fuel necessary to overcome engine
friction. Often, these improvements are
difficult to measure in everyday driving,
but in a year’s time they can offer
significant cost and energy savings.

RECOMMENDED SAE
VISCOSITY NUMBEREngine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operation (starting and oil flow). Lower
viscosity engine oils can provide better fuel
economy and cold weather performance,
however, higher viscosity engine oils are
required for satisfactory lubrication in hot
weather. Using oils of any viscosity other
than those recommended could result in
engine damage.
These lubricants and fluids are recommended for use in your vehicle.*1)
Refer to the recommended SAE viscosity numbers on the this page.
* Recommended for the Canadian climate.
Lubricant Classification
Engine oil* API Service SJ, SL or above,
ILSAC GF-3 or above
Manual transaxle oil* API Service GL-4 (SAE 75W-85)
Automatic trasaxle fluid SK ATF SP-III or Diamond ATF SP-III
Power steering fluid PSF-IV
Brake/clutch fluid SAEJ1703 or FMVSS116 DOT-3 DOT-4
✻
NOTICE
Always be sure to clean the area
around any filler plug, drain plug,
or dipstick before checking or
draining any lubricant. This is
especially important in dusty or
sandy areas and when the vehicle is
used on unpaved roads. Cleaning
the plug and dipstick areas will
prevent dirt and grit from entering
the engine and other mechanisms
that could be damaged.

7-42HEADLIGHT AIMING
ADJUSTMENTBefore performing aiming adjustment,
make sure of the following.
1. Keep all tires inflated to the correct
pressure.
2. Place the vehicle on level ground and
press the front bumper & rear
bumper down several times.
3. See that the vehicle is unloaded
(except for full levels of coolant,
engine oil and fuel, and spare tire, jack,
and tools). Have the driver sit in the
driver’s seat or use equivalent weight.4. Clean the headlight lenses and turn
on the headlight (Low beam).
5. Open the hood.
6. Draw a vertical line (through the
center of each headlight) and the
horizontal line (through the center of
each headlight) on the aiming screen.
1) Horizontal line dimension from
ground: 628 mm (24.72 in)
2) Distance between each vertical
line : 1,306 mm (49.17 in)
And then, draw a parallel line at 30
mm (1.18 in) place under the
horizontal line.
7. Adjust each cut-off line of the low
beam to the parallel line with a
Phillips screwdriver.
ADJUSTMENT AFTER
HEADLIGHT ASSEMBLY
REPLACEMENTIf the vehicle has had front body repair
and the headlight assembly has been
replaced, the headlight aiming should be
checked using the aiming screen as
shown in the illustration. Turn on the
headlight switch. (Low Beam Position)
1. Adjust headlights so that main axis of
light is parallel to center line of the
body and is aligned with point “P”
shown in the illustration.
