G050500AUN Timing belt (if equipped)
Inspect all parts related to the timing belt
for damage and deformation. Replace
any damaged parts immediately.
G050600AUN-EA
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or fuelfiller cap is correctly replaced. G050700AUN
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. 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 contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.G050800AFD
Air cleaner filter
A Genuine HYUNDAI air cleaner filter is recommended when the filter isreplaced.
G050900AUN-EA
Spark plugs (for petrol engine)
Make sure to install new spark plugs of
the correct heat range. G051000AFD-EA
Valve clearance (if equipped)
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorised HYUNDAI dealer should
perform the operation.
G051100AUN Cooling system
Check the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
G051200AUN Coolant The coolant should be changed at the
intervals specified in the maintenance
schedule.

FUEL FILTER (FOR DIESEL)
G150100AFD-EA
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 itsbottom.
If water accumulates in the fuel filter, the
warning light comes on when the ignition
switch is in the ON position.
If the light is turned on, take your car to
the authorised HYUNDAI dealer and
have drain the water and checked thesystem. G150200AFD
Fuel filter cartridge replacement
✽✽NOTICE
When replacing the fuel filter cartridge, use HYUNDAI genuine parts.
ONF055004
CAUTION
If the water accumulated in the fuel filter is not drained at proper times,
damages to the major parts such asthe fuel system can be caused bywater permeation in the fuel filter.

EMISSION CONTROL SYSTEM
G270000AFD-EA
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Service Passport
in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all Australian
Design Rules (ADR) requirements. There are three emission control sys-
tems 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 rec-
ommended that you have your car
inspected and maintained by an autho-
rised HYUNDAI dealer in accordancewith the maintenance schedule in this
manual. Caution for the Inspection and
Maintenance Test (With Electronic
Stability Program (ESP) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability
Program (ESP) system off by press-
ing the ESP switch.
After dynamometer testing is com- pleted, turn the ESP system back on
by pressing the ESP switch again.
G270100AUN
1. Crankcase emission control system
The positive crankcase ventilation sys-
tem 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 valveinto the induction system. G270200AFD-EA
2. Evaporative emission control
System
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the atmos-
phere.
G270201AUN-EA
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.

Engine 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.
