EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the car is being
driven in severe conditions, more fre-
quent oil and filter changes are required.
Drive belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation
and replace if necessary. Drive belts
should be checked periodically for proper
tension and adjusted as necessary.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven, damage
the emission system and cause multiple
issues such as hard starting. If an exces-
sive amount of foreign matter accumu-
lates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections. Fuel filters should be installed
by an authorized HYUNDAI dealer.
Fuel lines, fuel hoses and connec-
tions
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have an
authorized HYUNDAI dealer replace any
damaged or leaking parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.
Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. 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 contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present.Hoses should be replaced immediately if
there is any evidence of deterioration or
damage.
Air cleaner filter
A Genuine HYUNDAI air cleaner filter is
recommended when the filter is replaced.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.

Maintenance

Changing the engine oil and filter
Have engine oil and filter changed by an
authorized HYUNDAI dealer according to
the Maintenance Schedule at the begin-
ning of this section.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 climate.
ENGINE COOLANT
CALIFORNIA PROPOSI-
TION 65 WARNING
Engine oil contains chemicals
known to the State of California to
cause cancer, birth defects, and
reproductive harm.
Used engine oil may cause irrita-
tion 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 ani-
mals. Always protect your skin by
washing your hands thoroughly
with soap and warm water as soon
as possible after handling used oil.

Maintenance
Checking the coolant level
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine is cool.
If the coolant level is low, add enough
distilled (deionized) or soft water. Bring
the level to F, but do not overfill. If fre-
quent additions are required, see an
authorized HYUNDAI dealer for a cooling
system inspection.

(Continued)
Even if the engine is not operat-ing, do not remove the radiator
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.
WARNING
Removing radiator
cap
Never attempt to remove the radi-ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
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 cool-
ing system. When you are sure all
the pressure has been released,
press down on the cap, using a
thick towel, and continue turning
counterclockwise to remove it.
(Continued)
WARNING
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 tem-
perature decreases, the electric
motor will automatically shut off.
This is a normal condition. If your
vehicle is equipped with GDI, the
electric motor (cooling fan) may
operate until you disconnect the
negative battery cable.
