OMD044048
■Type A
■Type BWARNING
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could cause severe
burns. Wait until the engine is
cool before adding coolant to
the reservoir.
CAUTION
If the gauge pointer moves
beyond the normal range area
toward the “H” position, it indi-
cates overheating that may
damage the engine.
Do not continue driving with an
overheated engine. If your vehi-
cle overheats, refer to “If the
Engine Overheats” in chapter 6.

6.If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7.Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call an
authorised HYUNDAI dealer for
assistance.

What to do in an emergency
CAUTION
• Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked 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.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed at the frequencies indicated
to help ensure safe, dependable
operation of your vehicle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labour, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check the coolant level in the
coolant reservoir.
• Check the windscreen washer fluid
level.
• Look for under-inflated tyres.
• Check the radiator and condenser.
Check if the front of the radiator
and condenser are clean and not
blocked with leaves, dirt or insects
etc.
If any of the above parts are
extremely dirty or you are not sure
of their condition, we recommend
that you contact an authorised
HYUNDAI dealer.
Whilst operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
• Notice if your vehicle constantly
turns slightly or “pulls” to one side
when travelling on a smooth, level
road.
• When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or a “hard-to-push” brake pedal.
• If any slipping or changes in the
operation of your transaxle occurs,
check the transaxle fluid level.
• Check automatic transaxle P
(Park) function.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injuries.

Maintenance
8 7
At least monthly:
• Check the coolant level in the
engine coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flash-
ers.
• Check the inflation pressures of all
tyres including the spare.
At least twice a year
(i.e., every Spring and Autumn):
• Check the radiator, heater and air
conditioning hoses for leaks or
damage.
• Check the windscreen washer
spray and wiper operation. Clean
wiper blades with clean cloth
dampened with washer fluid.
• Check the headlight alignment.
• Check the muffler, exhaust pipes,
shields and clamps.
• Check the lap/shoulder belts for
wear and function.
• Check for worn tyres and loose
wheel nuts.
At least once a year:
• Clean the body and door drain
holes.
• Lubricate the door hinges and
checks, and bonnet hinges.
• Lubricate the door and bonnet
locks and latches.
• Lubricate the door rubber weather-
strips.
• Check the air conditioning system.
• Inspect and lubricate automatic
transaxle linkage and controls.
• Clean the battery and terminals.
• Check the brake/clutch fluid level.

Maintenance
Cooling system
Check cooling system components,
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.
Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance sched-
ule.
Automatic transaxle fluid
(if equipped)
Automatic transaxle fluid should not
be checked under normal usage
conditions.
We recommend that the automatic
transaxle fluid changed by an autho-
rised HYUNDAI dealer according to
the maintenance schedule.
✽NOTICE
Automatic transaxle fluid colour is
basically red.
As the vehicle is driven, the auto-
matic transaxle fluid will begin to
look darker.
It is a normal condition and you
should not judge the need to replace
the fluid based upon the changed
colour.
CAUTION
The use of a non-specified fluid
could result in transaxle mal-
function and failure.
Use only specified automatic
transaxle fluid. (Refer to
“Recommended lubricants and
capacities” in section 8.)

ENGINE COOLANT
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 level at least once a year, at
the beginning of the winter season,
and before travelling to a colder cli-
mate.Checking the coolant level(Continued)
• 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
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 anticlock-
wise to remove it.
• Even if the engine is not oper-
ating, do not remove the radi-
ator 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 injuries.
WARNING
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.
(Continued)
CAUTION
• Do not drive with no engine
coolant. It may cause water
pump failure and engine
seizure, etc.
• 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.

727
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 (Full) and L (Low)
marked 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 (Full), but do not overfill. If
frequent additions are required, we
recommend that the system be
inspected by an authorised
HYUNDAI dealer.
Recommended engine coolant
• Use only soft (distilled) water in the
coolant mixture.
• The engine in your vehicle has alu-
minium 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 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.WARNING
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.

Changing the coolant
We recommend that the coolant be
replaced by an authorised HYUNDAI
dealer.
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 injuries.
OMD071005L
CAUTION
Put a thick cloth or fabric
around the radiator cap before
refilling the coolant in order to
prevent the coolant from over-
flowing into engine parts such
as the alternator.
WARNING -Coolant
• Do not use radiator coolant or
antifreeze 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.
