Maintenance
Changing the coolant
Have coolant changed by an authorized
HYUNDAI dealer according to the
Maintenance Schedule at the beginning
of this section.
OBH072005L
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 pres-
sure causing serious injury.
CAUTION
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 generator.
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 solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es so that evaporated 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 performance.
Vehicle modifications
• This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or dura-
bility and may even violate governmen-
tal safety and emissions regulations.
In addition, damage or performance
problems resulting from any modifica-
tion may not be covered under warran-
ty.
• If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage, bat-
tery discharge and fire. For your safety,
do not use unauthorized electronic
devices.
Engine exhaust gas precautions (car-
bon monoxide)
• Carbon monoxide can be present with
other exhaust fumes. Therefore, if you
smell exhaust fumes of any kind inside
your vehicle, have it inspected and
repaired immediately. If you ever sus-
pect exhaust fumes are coming into
your vehicle, drive it only with all the
windows fully open. Have your vehicle
checked and repaired immediately.
WARNING- Exhaust
Engine exhaust gases contain car-
bon monoxide (CO). Though color-
less and odorless, it is dangerous
and could be lethal if inhaled.
Follow the instructions on this
page to avoid CO poisoning.

Refer to “Fuel requirements” in section 1
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.
These lubricants and fluids are recommended for use in your vehicle.
*
1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econ-
omy 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.

3: If the API service SM or ACEA A5 engine oil is not available in your country, you are able to use API service SL or ACEA A3.
