Maintenance
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 ensure
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
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.
When assembling parts, be sure to
wipe out foreign substances inside
and outside of the boot bottom of the
ignition coil and the insulator of the
spark plug with a soft cloth to prevent
contamination of the spark plug insu-
lator.
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 mainte-
nance schedule.The use of a non-specified fluid
could result in transmission
malfunction and failure. Use
only the specified transmission
fluid (refer to "Recommended
Lubricants and Capacities" in
chapter 8).

Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake/Clutch Fluid
Check the brake/clutch fluid level in
the brake/clutch fluid reservoir. The
level should be between the MIN and
the MAX marks on the side of the
reservoir. Use only hydraulic
brake/clutch fluid conforming to DOT
3 or DOT 4 specification.
Parking Brake
Inspect the parking brake system
including the parking brake pedal
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.
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 connections or
replace parts as necessary.
Suspension Mounting Bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering Gear Box, Linkage &
Boots/Lower Arm Ball Joint
With the vehicle stopped and the
engine off, check for excessive free-
play in the steering wheel. Check the
linkage for bends or damage. Check
the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
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
Engine oil is used for lubricating,
cooling, and operating various
hydraulic components in the engine.
Engine oil consumption while driving
is normal, and it is necessary to
check and refill the engine oil regu-
larly. Also, check and refill the oil
level within the recommended main-
tenance schedule to prevent deterio-
ration of oil performance. Check the
engine oil following the below proce-
dure.
1. Follow all of the oil manufacturer's
precautions.
2. Be sure the vehicle is on the level
ground in P (Park) with the park-
ing brake set and the wheels
blocked.
3. Turn the engine on and warm the
engine up until the coolant tem-
perature reaches a constant nor-
mal temperature.
4. Turn the engine off, remove the oil
filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to
return to the oil pan.
5. Wipe the dipstick clean and re-
insert it fully.6. Pull the dipstick out again and
check the level.7. If the oil level is below L, add
enough oil to bring the level to F.
Use only the specified engine oil.
(refer to "Recommended Lubricants
and Capacities" in chapter 8).

Maintenance
To prevent damage to your
engine:
• Do not spill engine oil when
adding or changing engine oil.
Wipe off spilled oil immediately.
• The engine oil consumption may
increase while you break in a
new vehicle and it will be stabi-
lized after driving 4,000 miles
(6,000 km).
• The engine oil consumption can
be affected by driving habits, cli-
mate conditions, traffic condi-
tions, oil quality, etc. Therefore, it
is recommended that you
inspect the engine oil level regu-
larly and refill it if necessary.
Checking 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
chapter.
• If the maintenance schedule to
replace engine oil is exceeded, the
engine oil performance may deteri-
orate, and the engine condition
may be affected. Therefore,
replace the engine oil according to
the maintenance schedule.• To keep the engine in optimal con-
dition, use the recommended
engine oil and filter. If the recom-
mended engine oil and filter are
not used, replace it according to
the maintenance schedule under
severe usage conditions.
• The purpose of the maintenance
schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.
NOTICE
CALIFORNIA PROPOSITION 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 irritation
or cancer of the skin if left in
contact with the skin for pro-
longed periods of time. Always
protect your skin by washing
your hands thoroughly with

ENGINE COOLANT
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.
• 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.
• Do not drive with no engine
coolant. It may cause water
pump failure and engine seizure,
etc.Checking the Engine 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 MAX and MIN (or 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
distilled (deionized) water to bring the
level to the F mark, 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 only dis-
tilled (deionized) 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 damage.
• The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol
with phosphate 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.

Maintenance
For mixing percentage, refer to the
following table:
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest 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.

Maintenance
The electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature 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.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.
WARNING
Never remove the
engine coolant cap or
the drain plug while
the engine and radia-
tor are hot. Hot
coolant and steam may blow
out under pressure, causing
serious injury.
WARNING
OJSN078010
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the engine coolant 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 sys-
tem. When you are sure all the
pressure has been released,
press down on the cap, using a
thick towel, and continue turn-
ing counterclockwise to remove
it.

Maintenance
Changing Engine Coolant
Have coolant changed by an author-
ized 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 prevent the coolant
from overflowing into engine
parts, such as the alternator.
NOTICE
Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
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.
