Maintenance
Air cleaner filter
A Genuine HYUNDAI air cleaner fil-
ter is recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. An authorized HYUNDAI dealer
should perform the operation.
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 mainte-
nance schedule.
Automatic transaxle fluid
Automatic transaxle fluid does not
need to be checked under normal
usage conditions.
But in severe conditions, the fluid
should be changed at an authorized
HYUNDAI dealer in accordance to
the scheduled maintenance at the
beginning of this chapter.
✽ ✽NOTICE
Automatic transaxle fluid color is
basically red.
As the vehicle is driven, the auto-
matic transaxle fluid will begin to
look darker.
This a 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 malfunction
and failure.
Use only specified automatic transaxle
fluid. (Refer to “Recommended lubri-
cants and capacities” in section 8.)

Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” and “MAX” marks on
the side of the reservoir. Use only
hydraulic brake fluid conforming to
DOT 3 or DOT 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake pedal or
lever and cables.
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.

for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on levelground.
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 re-insert it fully.
5. Pull the dipstick out again and check the level. The level should
be between F (Full) and L (Low). 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 lubricantsand capacities” in section 8.)

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.

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.

Filter inspection
If the vehicle is operated in the
severely air-polluted cities or on
dusty rough roads for a long period,
it should be inspected more fre-
quently and replaced earlier. When
you, the owner, replace the climate
control air filter, replace it performing
the following procedure, and be care-
ful to avoid damaging other compo-
nents.
Replace the filter according to the
maintenance Schedule.
Filter replacement
1. Open the glove box and remove
the support strap (1).
CAUTION - Air filter
maintenance
