Maintenance
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner Maintenance Schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of exhaust fumes
in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
Notice if your vehicle constantly turns slightly or "pulls" to one side when trav-
eling on smooth, level road.
When stopping, listen and check for unusual sounds, pulling to one side,
increased brake pedal travel or "hard-
to-push" brake pedal.
If any slipping or changes in the oper- ation of your transmission occurs,
check the transmission fluid level.
Check the automatic transmission/ dual clutch transmission P (Park) func-
tion.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-
mal).
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious burns
and other injuries.

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 satu-
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces-
sary.
Fuel Filter
A clogged-up fuel filter may limit the vehi-
cle driving speed, damage the emission
system, and cause the hard starting.
When a considerable amount of foreign
substances are accumulated in the fuel
tank, the fuel filter should be replaced.
Upon installing a new fuel filter, operate
the engine for several minutes, and
check the connections for any leakages.
Fuel filters should be installed by an
authorized HYUNDAI dealer.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorized HYUNDAI dealer replace
any damaged or leaking parts immedi-
ately.
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
a new vapor hose or fuel filler cap is cor-
rectly replaced.
Vacuum Crankcase Ventilation
Hoses (if equipped)
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 couplings, to make sure they
are secure, and that no leaks are pres-
ent. Hoses should be replaced immedi-
ately if there is any evidence of deterio-
ration 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.
Engine Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.

The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
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.Checking the Engine 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 the F and the L marks on the
side of the coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring the
level to the F mark, but do not overfill. If
frequent additions are required, we rec-
ommend that you see an authorized
HYUNDAI dealer for a cooling system
inspection.
Recommended engine coolant
When adding coolant, use only deion-
ized water, distilled water or soft water
for your vehicle and never mix hard
water in the coolant filled at the factory.
An improper coolant mixture can result in severe malfunction or engine dam-
age.
The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol with phos-
phate based coolant to prevent corro-
sion and freezing.
Do not use alcohol or methanol coolant or mix them with the specified 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.OAD076125

For mixing percentage, refer to the fol-
lowing table:
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the easi-
est to mix together as it will be the same
quantity of each. It is suitable to use for
most temperature ranges of
- 31°F and higher.The electric motor for the cooling fan is
controlled by engine coolant tempera-
ture, refrigerant pressure and vehicle
speed. As the engine coolant tempera-
ture decreases, the electric motor will
automatically shut off. This is a normal
condition. If your vehicle is equipped with
GDI, the electric motor for the cooling fan
may begin to operate at any time and
continue to operate until you disconnect
the negative battery cable.

Never remove the radia-
tor cap or the drain plug
while the engine and
radiator are hot. Hot
coolant and steam may
blow out under pressure, causing
serious injury.
Turn the engine off and wait until
the engine cools down. Use
extreme care when removing the
radiator cap. Wrap a thick towel
around it, and turn it counterclock-
wise slowly to the first stop. Step
back while the pressure is released
from the cooling system.
(Continued)
WARNING
(Continued)
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.
OAD075009
The electric motor for
the cooling fan may
continue to operate or
start up when the
engine is not running
and can cause serious injury. Keep
hands, clothing and tools away
from the rotating fan blades of the
cooling fan.

Changing Engine Coolant
Have coolant changed by an authorized
HYUNDAI dealer according to the
Maintenance Schedule at the beginning
of this chapter.
To prevent damage to engine parts,
put a thick towel around the radiator
cap before refilling the coolant to pre-
vent the coolant from overflowing into
engine parts, such as the generator.
Checking the Brake/Clutch
Fluid Level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap and
adding brake/clutch fluid, clean the area
around the reservoir cap thoroughly to
prevent brake/clutch fluid contamination.
If the level is low, add the specified
brake/clutch fluid to the MAX level. The
level will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake/clutch linings.
If the fluid level is excessively low, have
the brake/clutch system checked by an
authorized HYUNDAI dealer.
NOTICE
Do not use engine coolant or
antifreeze in the washer fluid reser-
voir.
Engine coolant can severely
obscure visibility when sprayed on
the windshield and may cause loss
of vehicle control resulting in an
accident.
Engine coolant may also cause
damage to paint and body trim.
WARNING
If the brake system requires fre-
quent additions of fluid this could
indicate a leak in the brake system.
Have the vehicle inspected by an
authorized HYUNDAI dealer.
WARNING
Do not allow brake/clutch fluid to
come in contact with your eyes. If
brake/clutch fluid comes in contact
with your eyes, flush your eyes with
clean water for at least 15 minutes
and get immediate medical atten-
tion.
