Adding Oil
HGK211
DOHC CVVT V6
The engine oil and filter should be changed at
those intervals specified in the maintenance
schedule in Section 5. If the car is being driven
in severe conditions, more frequent oil and filter
changes are required.
The procedure for changing the oil and filter is
as follows:
1. Park the car on level ground and set the
parking brake. Start the engine and let it
warm up until the needle on the coolant
temperature gauge moves above the lowest
mark. Turn the engine off and place the gear
selector lever in "P" (automatic) or reverse
gear (manual transaxle).4. When the oil has stopped draining, replace
the drain plug using a new washer and
retighten by turning it clockwise.
Tightening torque is:
4.5 ~ 4.0 kgf.m (2.0L)
4.5 ~ 3.5 kgf.m (2.7L)
5. Remove the oil filter by turning it counter-
clockwise with a oil filter wrench of the proper
size. A certain amount of oil will come out
when you remove the filter. So be sure to
have your drain pan in place underneath it.
6. Install a new oil filter in accordance with the
instructions on the carton or on the filter itself.
Do not over-tighten. (Tightening torque :

CHECKING AND CHANGING THE
ENGINE COOLANT
!
G050A01A-AAT
WARNING:Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is
removed. You could be seriously burned if
you do not observe this precaution. Do not
remove the radiator cap until the radiator is
cool to the touch. Be sure that the mounting surface on the
engine is clean and that the old gasket is
removed completely. Lubricate the new
gasket on the filter with clean engine oil
before installation.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-
ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is
suggested that it be placed in a sealed
container and taken to a service station for
reclamation. Do not pour the oil on the
ground or put it in with the household
trash.
PROPOSITION 65 WARNING:Used engine oil may cause irritation or
cancer of the skin if left in contact with the
skin for prolonged periods of time. Used
engine oil contains chemicals that have
caused cancer in laboratory animals. Al-
ways protect your skin by washing your
hands thoroughly with soap and warm
water as soon as possible after handling
used oil.
G050B01A-AAT
Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts.
Additional corrosion inhibitors or additives should
not be used. The cooling system must be
maintained with the correct concentration and
type of engine coolant to prevent freezing and
corrosion. Never allow the concentration of
antifreeze to exceed the 60% level or go below
the 35% level, or damage to the cooling system
may result. For proper concentration when
adding or replacing the engine coolant, refer to
the following table.

5. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "LOW" and "FULL".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
WARNING:The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the coolant fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition.

Changing the Spark Plugs
You will find it easier to change spark plugs if the
engine is cold. Always change one spark plug
at a time. This helps avoid getting the wires
mixed up.
1. Remove the engine rocker cover.
NOTE:It is recommended that the spark plugs (For
2.7L Engines) should be changed by an
authorized Hyundai dealer.
2. Using a clean cloth, remove any dirt that has
accumulated around the base of the spark
plug so it cannot fall into the cylinder when the
spark plug is removed.
HGK256
WARNING:It is recommended that the engine be cool
or cold when changing the spark plugs. If
the engine is hot, you could burn yourself
on the insulated connector, the spark plug
or the engine itself.
4. When preparing to remove the old spark
plug, guide the socket down over the spark
plug, being careful not to damage the ce-
ramic insulator. 3. To remove the spark plug cable, pull straight
up on the insulated connector, not the cable.
Pulling on the cable may damage the carbon
core conductor.
HGK257 G060B02GK-AAT
Replacing the Spark Plugs
The spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine
performance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always use spark
plugs recommended by Hyundai. The use of
other spark plugs can result in loss of perfor-
mance, radio interference or engine damage.
NOTE:When replacing the spark plugs, genuine
Hyundai replacement parts are recom-
mended.

AIR CONDITIONING CARE
G140A01A-AAT
Keeping the Condenser Clean
The air conditioning condenser (and engine
radiator) should be checked periodically for
accumulation of dirt, dead insects, leaves, etc.
These can interfere with maximum cooling ef-
ficiency. When removing such accumulations,
brush or hose them away carefully to avoid
bending the cooling fins.
!
G140C01A-AATLubrication
To lubricate the compressor and the seals in the
system, the air conditioning should be run for at
least 10 minutes each week. This is particularly
important during cool weather when the air
conditioning system is not otherwise in use.
G140B01A-AAT
Checking the Air Conditioning Opera-
tion
1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning set
at the maximum cold setting.
2. If the air coming out of the in-dash vents is
not cold, have the air conditioning system
inspected by your Hyundai dealer.
CAUTION:Running the air conditioning system for
extended periods of time with a low refrig-
erant level may damage the compressor.

22CHECKING THE BATTERY
!CAUTION:A burned-out fuse indicates that there is a
problem in the electrical circuit. If you re-
place a fuse and it blows as soon as the
accessory is turned on, the problem is
serious and should be referred to a Hyundai
dealer for diagnosis and repair. Never re-
place a fuse with anything except a fuse
with the same or a lower amperage rating.
A higher capacity fuse could cause damage
and create a fire hazard.

!
G210A01A-AAT
WARNING:Batteries can be dangerous! When working
with batteries, carefully observe the follow-
ing precautions to avoid serious injuries.
The fluid in the battery contains a strong solution
of sulfuric acid, which is poisonous and highly
corrosive. Be careful not to spill it on yourself or
the car. If you do spill battery fluid on yourself,
immediately do the following:
o If battery fluid is on your skin, flush the
affected areas with water for at least 15
minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your
eyes with water and get medical assistance
as soon as possible. While you are being
driven to get medical assistance, continue to
rinse your eyes by using a sponge or soft
cloth saturated with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk of
magnesia, eat a raw egg or drink vegetable
oil. Get medical assistance as soon as
possible.
1. Turn off the ignition and all other switches.
2. Open the fuse box and examine each fuse.
Remove each fuse by pulling it toward you
(a small "fuse puller" tool is contained in the
fuse box to simplify this operation).
3. Be sure to check all other fuses even if you
find one that appears to have burned out.
HXDFL1026-1
4. Replace the blown fuse by pressing a new
fuse of the same rating into place. The fuse
should be a snug fit. If it is not, have the fuse
clip repaired or replaced by a Hyundai dealer.
If you do not have a spare fuse, you may be
able to borrow a fuse of the same or lower
rating from an accessory you can tempo-
rarily get along without (the radio or cigarette
lighter, for example). Always remember to
replace the borrowed fuse.
NOTE:See page 6-36 for the fuse panel descrip-
tions.
