Maintenance
Air cleaner filter
We recommend that the air cleaner
filter be replaced by an authorised
HYUNDAI dealer.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check the cooling system parts,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transmission fluid
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid be changed by an
authorised HYUNDAI dealer accord-
ing to the maintenance schedule.
Information
Automatic transmission fluid colour is
basically red. As the vehicle is driven,
the automatic transmission fluid will
begin to look darker.
This is a normal condition. It does not
need to be replaced based on the
colour change.
The use of a non-specified fluid
could result in transmission mal-
function and failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended lubricants and
capacities” in section 8.)
NOTICE
i
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant concentration level at least
once a year, at the beginning of the
winter season, and before travelling
to a colder climate.
•When the engine overheats from
low engine coolant, suddenly
adding engine coolant may
cause cracks in the engine. To
prevent damage, add engine
coolant slowly in small quanti-
ties.
•Do not drive with no engine
coolant. It may cause water pump
failure and engine seizure, etc.

level
NOTICE
Removing radiator
cap
•Never attempt to remove the
radiator 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.
•Tu r n t h e e n g i n e o f f a n d w a i t
until it cools down. Use
extreme care when removing
the radiator cap. Wrap a thick
towel around it, and turn it
anticlockwise slowly to the
first stop. Step back whilst the
pressure is released from the
cooling system.

Maintenance
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated 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
distilled (deionized) water. Bring the
level to F (MAX), but do not overfill.
If frequent additions are required, we
recommend that the system be
inspected by an authorised HYUNDAI
dealer.
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times 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 rotating fan blades. As the
engine coolant temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.

(Continued)
When you are sure all the
pressure has been released,
press down on the cap, using
a thick towel, and continue
turning anticlockwise to
remove it.
•Even if the engine is not oper-
ating, do not remove the radia-
tor cap or the drain plug whilst
the engine and radiator are
hot. Hot coolant and steam
may still blow out under pres-
sure, causing serious injury.

Maintenance
Recommended engine coolant
•When adding coolant, use only
deionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
•The engine in your vehicle has alu-
minium engine parts and must be
protected a phosphate based eth-
ylene-glycol coolant to prevent cor-
rosion and freezing.
•DO NOT USE alcohol or methanol
coolant or mix them with the spec-
ified 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
following table.
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.
Changing the coolant
We recommend that the coolant be
replaced by an authorised HYUNDAI
dealer.
Put a thick cloth or fabric around
the radiator cap before refilling
the coolant in order to prevent the
coolant from overflowing into
engine parts such as the alterna-
tor.
NOTICE
i
•Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
•Engine coolant can severely
obscure visibility when
sprayed on the windscreen
and may cause loss of vehicle
control or damage to paint
and body trim.

Checking the washer fluid
level
The reservoir is translucent so that
you can check the level with a quick
visual inspection.
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary.
Plain water may be used if washer
fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
- Coolant
Do not use engine coolant or
antifreeze in the washer fluid
reservoir.

•Windscreen Washer fluid
agents contain some amounts
of alcohol and can be flamma-
ble under certain circum-
stances. Do not allow sparks
or flame to contact the washer
fluid or the washer fluid reser-
voir. Damage to the vehicle or
occupants could occur.
•Windscreen washer fluid is
poisonous to humans and
animals. Do not drink and
avoid contacting windscreen
washer fluid. Serious injury or

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-
orated 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.
3. Exhaust emission control
system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
whilst maintaining good vehicle per-
for mance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
•If you use unauthorised electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorised
electronic devices.

in everyday driving, but in a year’s time, they can offer significant cost and energy savings.
