Maintenance
Automatic transmission fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid changed by an
authorised HYUNDAI dealer accord-
ing to the maintenance schedule.
Automatic transmission fluid
colour is basically red.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker.
It is normal condition and you
should not judge the need to
replace the fluid based upon the
colour change.
Manual transmission fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
Dual clutch transmission fluid
(if equipped)
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake/Clutch fluid
(if equipped)
Check brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” and “MAX” marks on
the side of the reservoir. Use only
hydraulic brake fluid conforming to
DOT 3 or DOT 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake lever (or
pedal) and cables.
NOTICE
The use of a non-specified fluid
could result in transmission
malfunction and failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended lubricants and
capacities” in section 8.)
CAUTION

Maintenance
Brake pads, calipers and
rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and the
engine off, check for excessive free-
play in the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant/
compressor
Check the air conditioning lines and
connections for leakage and dam-
age.

Checking the engine oil level
(Petrol engine)
1. Be sure the vehicle is on level
ground.2. Start the engine and allow it to
reach normal operating tempera-
ture.
3. Turn the engine off and wait for a
few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean,
and re-insert it fully.
5. Pull the dipstick out again and
check the level. The level should
be between F and L.

Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.
WARNING
Do not overfill the engine oil.
It may damage the engine.
Do not spill engine oil, when
adding or changing engine
oil. If you drop the engine oil
on the engine compartment,
wipe it off immediately.
When you wipe the oil level
gauge, you should wipe it with
a clean cloth. When mixed
with debris, it can cause
engine damage.
CAUTION

If it is near or at L, add enough oil to
bring the level to F.Do not overfill.
Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil.

Checking the engine oil and
filter
We recommend that the engine oil
and filter be replaced by an autho-
rised HYUNDAI dealer.
Used engine oil may cause irri-
tation or cancer of the skin if
left in contact with the skin for
prolonged periods of time. Used
engine oil contains chemicals
that have caused cancer in lab-
oratory animals. Always protect
your skin by washing your
hands thoroughly with soap
and warm water as soon as pos-
sible after handling used oil.

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.Checking the coolant level
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 MAX and 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 MAX, but do not
overfill.
If frequent additions are required, we
recommend that the system be
inspected by an authorised
HYUNDAI dealer.
When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
Do not drive without engine
coolant. It may cause water
pump failure and engine
seizure, etc.
CAUTION

Removing coolant
cap
Never attempt to remove the
coolant 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.
WARNING

7-36
Maintenance
Turn the engine off and wait
until it cools down. Use
extreme care when removing
the coolant 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.
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
coolant 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.
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 a 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.
WARNING
Make sure the coolant cap is
properly closed after refilling
coolant. Otherwise the engine
could be overheated whilst
driving
1. Check if the coolant cap label
is straight In front.
