EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter (cartridge)
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel filter be
replaced by a HYUNDAI authorised
repairer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connectionsr be
replaced by a HYUNDAI authorised
repairer.
WARNING - Diesel only
Never work on injection system
with engine running or within 30
seconds after shutting off
engine. High pressure pump,
rail, injectors and high pressure
pipes are subject to high pres-
sure even after the engine
stopped. The fuel jet produced
by fuel leaks may cause serious
injury, if it touch the body.
People using pacemakers
should not move than 30cm
closer to the ECU or wiring har-
ness within the engine room
whilst engine is running, since
the high currents in the
Common Rail system produce
considerable magnetic fields.
CAUTION
When you are inspecting the
belt, place the ignition switch in
the LOCK/OFF or ACC position.

Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapour hose or fuel filler cap is cor-
rectly replaced.
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 assure
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
We recommend that the air cleaner
filter be replaced by a HYUNDAI
authorised repairer.
Spark plugs
(for petrol engine)
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
(for petrol engine)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by a HYUNDAI autho-
rised repairer.
WARNING
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

FUEL FILTER (FOR DIESEL)
Draining water from fuel filter
The fuel filter for diesel engine plays
an important role of separating water
from fuel and accumulating the water
in its bottom.
If water accumulates in the fuel filter,
the warning light comes on when the
ignition switch is in the ON position.
If this warning light turned
on, we recommend that the
system be serviced by a
HYUNDAI authorised
repairer.
Fuel filter cartridge replace-
ment
✽NOTICE
When replacing the fuel filter car-
tridge, we recommend that you use
parts for replacement from a
HYUNDAI authorised repairer.
ODMNMC2025R
CAUTION
If the water accumulated in the
fuel filter is not drained at prop-
er times, damages to the major
parts such as the fuel system
can be caused by water perme-
ation in the fuel filter.

EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the
Warranty Booklet 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 sys-
tem
(2) Evaporative emission control sys-
tem
(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 a
HYUNDAI authorised repairer in
accordance with the maintenance
schedule.Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
• To prevent the vehicle from mis-
firing during dynamometer test-
ing, turn the Electronic Stability
Control (ESC) system off by
pressing the ESC switch.
• After dynamometer testing is
completed, turn the ESC system
back on by pressing the ESC
switch again.
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 con-
trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the
atmosphere.
Canister
Fuel vapours generated inside the
fuel tank are absorbed and stored in
the onboard canister. When the
engine is running, the fuel vapours
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 evap-
ourated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evapourated fuel
to the engine.
