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.
Manual transmission fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
Automatic transmission fluid
Automatic transmission fluid should
not 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.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
CAUTION
The use of a non-specified fluidcould result in transmissionmalfunction and failure.
Use only specified automatictransmission fluid. (Refer to“Recommended lubricants andcapacities” in section 8.)

Maintenance
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.Checking the coolant level
ENGINE COOLANT
(Continued)
Even if the engine is not oper-ating, do not remove the radi-
ator 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 radiator cap while the engine
is operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal
injury from escaping 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
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.

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 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) 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.
Recommended engine coolant
When adding coolant, use only
deionized 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.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 temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.

Maintenance
For mixture percentage, refer to the
following table.Changing the coolant
Have coolant changed by an author-
ized HYUNDAI dealer according to
the Maintenance Schedule at the
beginning of this section.
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.
CAUTION
Put a thick cloth around the radiator cap before refilling thecoolant in order to prevent thecoolant from overflowing intoengine parts such as the gener-ator.
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.

Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve
(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control
system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust gas precautions
(carbon monoxide)
Carbon monoxide can be present with other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your vehi-
cle, have it inspected and repaired
immediately. If you ever suspect
exhaust fumes are coming into
your vehicle, drive it only with all
the windows fully open. Have your
vehicle checked and repaired
immediately.
Do not operate the engine in con- fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in or
out of the area.
When the vehicle is stopped in an open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
Never sit in a parked or stopped vehicle for any extended time with
the engine running.

RECOMMENDED LUBRICANTS AND CAPACITIES
These lubricants and fluids are recommended for use in your vehicle.
*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo my by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
*
3If the API service SM engine oil is not available in your country, you are able to use API service SL, ILSAC GF-4, ACEA 3.
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
