Maintenance
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 an authorised
HYUNDAI dealer.
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 an authorised
HYUNDAI dealer.
Cooling system
Check the cooling system parts,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

Maintenance
4. Replace the air cleaner filter. 5. Pull up the lever(1) to the LOCK
position.
6. Rise up the cover (2) until the
hooks on the cover are securely
fastened into the latches (3).
7. Check if the cover is firmly
installed.
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-
ment more often than the usual rec-
ommended intervals (refer to
“Maintenance Under Severe Usage
Conditions” in this chapter).
Do not drive with the air cleaner
filter removed. This will result in
excessive engine wear.
When removing the air cleaner
filter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
Use HYUNDAI genuine parts,
use of non-genuine parts could
damage the air flow sensor.

Filter inspection
If the vehicle is operated in the
severely air-polluted cities or on
dusty rough roads for a long period,
it should be inspected more fre-
quently and replaced earlier. When
you, the owner, replace the climate
control air filter, replace it performing
the following procedure, and be care-
ful to avoid damaging other compo-
nents.
Replace the filter according to the
Maintenance Schedule.
Install a new climate control air filter
in the correct direction with the
arrow symbol(
↓ ↓) facing downwards.
Otherwise, the climate control
effects may decrease, possibly
with a noise.
Filter replacement
1.With the glove box open, remove
the stoppers on both sides.
2.Open the glove box and remove
the support strap (1).3. Remove the climate control air fil-
ter case whilst pressing the lock
on the left side of the cover.

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
Australian Design Rules (ADR)
requirements.
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
vehicle inspected and maintained by
an authorised 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 con-
trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the
atmosphere. For the Inspection and
Maintenance Test (With
Electronic Stability Control
(ESC) system)
To prevent the vehicle from
misfiring during dynamome-
ter testing, turn the Electronic
Stability Control (ESC) sys-
tem off by pressing the ESC
switch.
After dynamometer testing is
completed, turn the ESC sys-
tem back on by pressing the
ESC switch again.
