Changing the engine oil and
filter
Have engine oil and filter changed by
an authorized HYUNDAI dealer
according to the Maintenance
Schedule at the beginning 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.
WARNING
-
California proposition 65
Engine oil contains chemicals
known to the State of California
to cause cancer, birth defects
and reproductive harm. Used
engine oil may cause irritation or
cancer of the skin if left in con-
tact with the skin for prolonged
periods of time. Always protect
your skin by washing your
hands thoroughly with soap and
warm water as soon as possible
after handling used oil.
ENGINE COOLANT
WARNING - Cooling fan
Use caution when
working near the
blade of the cooling
fan. The electric
motor (cooling fan) is
controlled by engine coolant
temperature, refrigerant pres-
sure and vehicle speed. It may
sometimes operate even when
the engine is not running.
Your vehicle equipped with GDI,
the electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.
Not heeding these warnings
could result in serious injuries.

Maintenance
Checking the coolant level
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) marks
on the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring
the level to F (Full), but do not overfill.
If frequent additions are required, see
an authorized HYUNDAI dealer for a
cooling system inspection.
Recommended engine coolant
When adding coolant, use onlydeionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol-
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.

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 con-
tinue turning counterclockwise to
remove it.
Changing the coolant
Have the coolant changed by an
authorized HYUNDAI dealer accord-
ing to the Maintenance Schedule at
the beginning of this section.
Put a thick cloth around the radiator
cap before refilling the coolant in
order to prevent the coolant from
overflowing into engine parts such as
the alternator.
WARNING - Radiator cap
Do not remove the
radiator cap when the
engine and radiator
are hot. Scalding hot
coolant and steam
may blow out under pressure
causing serious injury.
OHG071006L
CAUTION - Removing
radiator cap
Never attempt to remove the radiator cap while the engineis operating or hot.Doing so might lead
to cooling system and engine damage.

Maintenance
BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.If the level is low, add fluid to the
MAX (Maximum) level. The level will
fall with accumulated mileage. This is
a normal condition associated with
the wear of brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized HYUNDAI dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsor capacities” in section 8.)
Never mix different types of fluid.
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized HYUNDAI dealer.
Brake fluid, which has been exposed
to open air for an extended time
should never be used as its quality
cannot be guaranteed. It should be
disposed of properly.
OVG079007L
CAUTION - Proper fluid
Only use brake fluid in brakesystem. Small amounts ofimproper fluids (such as engineoil) can cause damage to thebrake system.
CAUTION - Brake fluid
Do not allow brake fluid to con-tact the vehicle's body paint, aspaint damage will result.
WARNING - Brake fluid
When changing and adding
brake fluid, handle it carefully.
Do not let it come in contact with
your eyes. If brake fluid should
come in contact with your eyes,
immediately flush them with a
large quantity of fresh tap water.
Have your eyes examined by a
doctor as soon as possible.

WASHER FLUID
Checking the washer fluid
level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if wash-
er fluid is not available. However, use
washer solvent with antifreeze char-
acteristics in cold climates to prevent
freezing.
Checking the parking brake
Check the stroke of the parking brake
by counting the number of “clicks’’
heard while fully applying it from the
released position. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade.
If the stroke is more or less than
specified, have the parking brake
adjusted by an authorized HYUNDAI
dealer.
Stroke : 5 “clicks’’ at a force of
66 lbs (30 kg, 294 N).

WARNING - Windshield
fluid
Do not drink the windshield
washer fluid. The windshield
washer fluid is poisonous to
humans and animals.
WARNING - Coolant
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.
WARNING - Flammable
fluid
Do not allow the washer fluid to
come in contact with open
flames or sparks. The windshield
washer fluid is flammable under
certain circumstances. This can
result in a fire which could result
in serious injuries.

WIPER BLADES
Blade inspection
Commercial hot waxes applied by
automatic car washes have been
known to make the windshield diffi-
cult to clean. Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the win-
dow and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water
Blade replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.
