Maintenance
Vapour hose and fuel filler capThe 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 fuel
filler cap is correctly replaced.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 moving
component 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.
Air cleaner filterWe recommend that you use air cleaner
filter for replacement from a HYUNDAI
authorised repairer.Spark plugs (for petrol engine)Make sure to install new spark plugs of
the correct heat range.Cooling systemCheck the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.CoolantThe coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid
(if equipped)Inspect the manual transaxle fluid
according to the maintenance schedule.Automatic transaxle fluid
(if equipped)Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, we recommend
that the fluid be changed by a HYUNDAI
authorised repairer in accordance to the
scheduled maintenance at the beginning
of this chapter.✽ ✽NOTICEAutomatic transaxle fluid colour is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed colour.
WARNING
Do not disconnect and inspect
spark plugs when the engine is hot.
You may burn yourself.

ENGINE COOLANT
Changing the engine oil and filterWe recommend that the engine oil and
filter be replaced by a HYUNDAI autho-
rised repairer. The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant concentration level at least once
a year, at the beginning of the winter sea-
son, and before travelling to a colder cli-
mate.
WARNING
Prolonged and repeated contact
with used engine oils may result in
serious skin disorders including
dermatitis and cancer. Avoid con-
tact with skin as far as possible and
always wash thoroughly after any
contact. Keep used oils out of
reach of children. It is illegal to pol-
lute drains, water courses and soil.
Use only authorised waste collec-
tion facilities including civic ameni-
ty sites and garages for the dispos-
al of used oil and oil filters. If in
doubt, contact the local authority
for disposal instructions.
CAUTION
 When the engine overheats from
low engine coolant, suddenlyadding engine coolant may causecracks in the engine. To prevent damage, add engine coolantslowly in small quantities.
 Do not drive with no engine coolant. It may cause water pumpfailure and engine seizure, etc.

Maintenance
Checking the coolant level
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks on
the side of the coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (MAX), but do not overfill. If fre-
quent coolant refill is required, we rec-
ommend that the system be inspected by
a HYUNDAI authorised repairer.

(Continued)
 Even if the engine is not operat-ing, do not remove the radiator
cap or the drain plug whilst the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
WARNING
The electric motor (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate even
when the engine is not running.
Use extreme caution when working
near the blades of the cooling fan
so that you are not injured by a
rotating fan blades. As the engine
coolant temperature decreases, the
electric motor will automatically
shut off. This is a normal condition.
If your vehicle is equipped with
GDI, the electric motor (cooling fan)
may operate until you disconnect
the nagative battery cable.
WARNING
Removing radiator
cap
 Never attempt to remove the radi- ator cap whilst the engine is
operating or hot. Doing so might
lead to cooling system and
engine damage and could result
in serious personal injury from
escaping hot coolant or steam.
 Turn the engine off and wait until it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop.
Step back whilst the pressure is released from the cooling sys-
tem. When you are sure all the
pressure has been released,
press down on the cap, using a
thick towel, and continue turning
counterclockwise to remove it.

7Recommended engine coolant When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
 The engine in your vehicle has alumini- um engine parts and must be protected
by an ethylene-glycol-based coolant to
prevent corrosion and freezing.
 DO NOT USE alcohol or methanol coolant or mix them with the specified
coolant.
 Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.
Changing the coolantWe recommend that the coolant be
replaced by a HYUNDAI authorised
repairer.
WARNING
Radiator cap
Do not remove the radiator cap
when the engine and radiator are
hot. Scalding hot coolant and
steam may blow out under pres-
sure causing serious injury.

CAUTION
Put a thick cloth or fabric around
the radiator cap before refilling the coolant in order to prevent thecoolant from overflowing intoengine parts such as generator.
WARNING -
Coolant
 Do not use radiator coolant or anti -
freeze in the washer fluid reservoir.
 Radiator coolant can severely obscure visibility when sprayed
on the windscreen and may
cause loss of vehicle control or
damage to paint and body trim.

7EMISSION CONTROL SYSTEMThe 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 emission
regulations.
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 a
HYUNDAI authorised repairer in accor-
dance with the maintenance schedule. Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
 To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch.
 After dynamometer testing is com- pleted, turn the ESC system back on
by pressing the ESC switch again.
1. Crankcase emission control systemThe 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 valve
into the induction system.
2. Evaporative emission controlSystemThe Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the atmos-
phere.CanisterFuel 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 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.
