3. Pull the fuel filler door out (1) to fully
open.
4. To remove the fuel tank cap (2), turn
it counterclockwise. You may hear a
hissing noise as the pressure inside
the tank equalizes.
5. Place the cap on the fuel filler door (3).
WARNING
• Your diesel vehicle is equipped with
the specially-designed breakaway
valve inside the filler inlet to prevent
accidental fuel blending with petrol.
The fuel inlet of your diesel vehicle
cannot be fitted with a standard
petrol nozzle. Do not forcefully insert
a standard petrol nozzle into the filler
inlet of your diesel vehicle. It may
damage your vehicle.
• Some gas stations may still use
standard petrol nozzles for diesel
refueling. If you find that a diesel
nozzle is narrower than the fuel
filler inlet diameter of your diesel
vehicle, we recommend you to find/
visit another gas station, which
is equipped with standard diesel
nozzles.
• Fully insert a standard diesel nozzle
into the filler inlet to open the
breakaway valve. If the nozzle is not
fully inserted into the filler inlet, it
causes diesel fuels to flow out of the
fuel tank.
i Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break the
ice and release the door. Do not pry on the
door. If necessary, spray around the door
with an approved de-icer fluid (do not use
radiator anti-freeze) or move the vehicle
to a warm place and allow the ice to melt.

Maintenance
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
emission regulations.
There are three emission control systems
which are as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function
of the emission control systems, it
is recommended that you have your
car inspected and maintained by
an authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.1. Crankcase emission control
system
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase. This
system supplies fresh filtered air to the
crankcase through the air intake hose.
Inside the crankcase, the fresh air mixes
with blow-by gases, which then pass
through the PCV valve into the induction
system.
2. Evaporative emission control
system
The Evaporative Emission Control
System is designed to prevent
fuel vapors from escaping into the
atmosphere.
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 controlled by the Engine Control
Module (ECM); when the engine coolant
temperature is low during idling, the
PCSV closes 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.
