ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach
normal operating temperature.
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.
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 components.
Use only the specified engine oil. (Refer
to “Recommended lubricants and capaci-
ties” in section 8.)
WARNING - Radiator hose
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.
ORBC070003
CAUTION
• Do not overfill with engine oil.
Engine damage may result.
• Do not spill engine oil, when
adding or changing engine oil. If
you drop the engine oil on the
engine room, wipe it off immedi-
ately.
• When you wipe the oil level
gauge, you should wipe it with a
clean cloth. When mixed with
debris, it can cause engine dam-
age.
CAUTION - Diesel engine
Overfilling the engine oil may cause
severe dieseling. It may lead to
engine damage accompanied with
abrupt engine speed increment,
combustion noise and white smoke
emission.

ENGINE COOLANT
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 level at least once a year, at the
beginning of the winter season, and
before travelling to a colder climate.Checking the coolant level
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 system. 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.
(Continued)
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 rotat-
ing 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 negative battery cable.
(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.
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, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.

725
Maintenance
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 and L marks on the side of the
coolant reservoir when the engine is
cool.If the coolant level is low, add enough
distilled (deionized) or soft water.
Bring the level to F, but do not overfill. If
frequent additions are required, see an
authorised HYUNDAI dealer for a cooling
system inspection.
To add coolant follow the below steps:
(Petrol Engine only)
1. Open the cap.
2. Pull the sliding neck up and turn it in
the direction of the arrow to fix it in
place.
3. Add coolant.

Recommended 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 alu-
minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
• 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 coolant
Have coolant changed by an authorised
HYUNDAI dealer according to the
Maintenance Schedule at the beginning
of this section.
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 around the radiator
cap before refilling the coolant in
order to prevent the coolant from
overflowing into engine parts such
as the generator.
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.

BRAKE/CLUTCH FLUID
Checking the brake/clutch fluid
level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings.
If the fluid level is excessively low, have
the brake or clutch system checked by an
authorised HYUNDAI dealer.
Use only the specified brake fluid. (Refer
to “Recommended lubricants or capaci-
ties” in section 8.)
Never mix different types of fluid.
✽NOTICE
Before removing the brake/clutch filler
cap, read the warning on the cap.
WARNING - Brake fluid
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
WARNING - Loss of brake
fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorised HYUNDAI dealer.
CAUTION
Do not allow brake fluid to contact
the vehicle's body paint, as paint
damage will result. Brake fluid,
which has been exposed to open air
for an extended time should never
be used as its quality cannot be
guaranteed. It should be disposed
of properly. Don't put in the wrong
kind of fluid. A few drops of miner-
al-based oil, such as engine oil, in
your brake system can damage
brake system parts.
ORBI071007
WARNING
Clean filler cap before removing.
Use only DOT3 or DOT4 brake/
clutch fluid from a sealed container.
