Maintenance
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-
rectly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
We recommend that the air cleaner
filter be replaced by an authorized
HYUNDAI dealer.
Spark plugs
(For gasoline engine)
Make sure to install new spark plugs
of the correct heat range.
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

Maintenance
Valve clearance
(For gasoline engine)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary.
We recommend that the system be
serviced by an authorized HYUNDAI
dealer.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.

transaxle fluid changed by an author-
ized HYUNDAI dealer according to
the maintenance schedule.
Information
Automatic transaxle fluid color is
basically red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.The use of a non-specified fluid
could result in transaxle malfunc-
tion and failure.
Use only specified automatic
transaxle fluid. (Refer to
"Recommended lubricants and
capacities" in chapter 8.)

Checking the engine oil level
1.Be sure the vehicle is on level
ground.
2.Start the engine and allow it to
reach normal operating tempera-
ture.3.Turn the engine off and wait for a
few minutes (about 5 minutes) for
the oil to return to the oil pan.
4.Pull the dipstick out, wipe it clean,
and reinsert it fully.
5.Pull the dipstick out again and
check the level. The level should be
between F (Full) and L (Low). Do not spill engine oil, when
adding or changing engine oil. If
you drop the engine oil on the
engine room, wipe it off immedi-
ately.
When you wipe the oil level gauge,
you should wipe it with a clean
cloth. When mixed with debris, it
can cause engine damage.
- Diesel Engine
Overfilling the diesel engine oil
may cause severe dieseling due to
the churning effect. It may damage
the diesel engine with the abrupt
engine speed incensement, com-
bustion noise, and white smoke
emission.
NOTICE
NOTICE
Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.

Maintenance
If it is near or at L (Low), add enough
oil to bring the level to F (Full).
Do not overfill.
Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil.
(Refer to "Recommended lubricants
and capacities" in chapter 8.)
Changing the engine oil and
filter
We recommend that the engine oil
and filter be replaced by an author-
ized HYUNDAI dealer.
Used engine oil may cause skin
irritation or cancer if left in con-
tact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory
animals. Always protect your
skin by washing your hands
thoroughly with soap and warm
water as soon as possible after
handling used oil.

The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season,
and before traveling to a colder cli-
mate.
Do not drive with no engine
coolant. It may cause water
pump failure and engine seizure,
etc.
When the engine overheats from
low engine coolant, suddenly
adding engine coolant may
cause cracks in the engine. To
prevent damage, add engine
coolant slowly in small quanti-
ties.Checking the coolant level
NOTICE
Removing radiator
cap
Never attempt to remove the
radiator cap while the engine
is operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hot
coolant or steam.
(Continued)
WARNING
(Continued)
Turn the engine off and wait
until it cools down. Use
extreme care when removing
the radiator cap. Wrap a thick
towel around it, and turn it
counterclockwise slowly to
the first stop. Step back while
the pressure is released from
the cooling system. When you
are sure all the pressure has
been released, press down on
the cap, using a thick towel,
and continue turning counter-
clockwise to remove it.
Even if the engine is not oper-
ating, do not remove the radi-
ator cap or the drain plug
while the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.

Maintenance
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F (Full) and L (Low)
marked on the side of the coolant
reservoir when the engine is cool.If the coolant level is low, add enough
distilled (deionized) water (except
Middle East) or add enough pre-
mixed coolant (for Middle East).
Bring the level to F (Full), but do not
overfill. If frequent additions are
required, we recommend that the
system be inspected by an author-
ized HYUNDAI dealer. The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use
extreme caution when working
near the blades of the cooling
fan so that you are not injured
by a rotating fan blades. As the
engine coolant temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.

Maintenance
Recommended engine coolant
Use only soft (distilled) water in the
coolant mixture.
The engine in your vehicle has alu-
minum engine parts and must be
protected by a phosphate-based
ethylene glycol coolant for alu-
minum radiator based coolant to
prevent corrosion and freezing.
DO NOT USE alcohol or methanol
coolant or mix them with the spec-
ified coolant.
Do not use a solution that contains
more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.
For mixture percentage, refer to the
following table.
Changing the coolant
We recommend that the coolant be
replaced by an authorized HYUNDAI
dealer.
Put a thick cloth or fabric around
the radiator cap before refilling
the coolant in order to prevent the
coolant from overflowing into
engine parts such as the alterna-
tor.
