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.

Diesel Particulate Filter (if equipped)
The Diesel Particulate Filter (DPF) sys-
tem removes the soot emitted from the
vehicle.
Unlike a disposable air filter, the DPF
system automatically burns (oxidizes)
and removes the accumulated soot
according to the driving condition. In
other words, the active burning by engine
control system and high exhaust gas
temperature caused by normal/high driv-
ing condition burns and removes the
accumulated soot.
However, if the vehicle continues to be
driven at low speed for long time, the
accumulated soot may not be automati-
cally removed because of low exhaust
gas temperature. In this particular case,
the amount of soot is out of detection
limit, the soot oxidation process by
engine control system may not happen
and the malfunction indicator light may
blink.
When the malfunction indicator light
blinks, it may stop blinking by driving the
vehicle at more than 60km/h (37 mph) or
at more than second gear with 1500 ~
2000 engine rpm for a certain time (for
about 25 minutes).If the malfunction indicator light contin-
ues to be blinked in spite of the proce-
dure, please visit an authorized
HYUNDAI dealer and then check the
DPF system.
If you continue to drive with the malfunc-
tion indicator light blinking for a long
time, the DPF system can be damaged
and fuel consumption can be worsen.
CAUTION - Diesel Fuel
(if equipped with DPF)
It is recommended to use the regu-
lated automotive diesel fuel for
diesel vehicle equipped with the
DPF system.
If you use diesel fuel including high
sulfur (more than 50 ppm sulfur)
and unspecified additives, it can
cause the DPF system to be dam-
aged and white smoke can be emit-
ted.
