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.

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.

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.

Maintenance
✽NOTICE
“C” (COLD) range is for reference only
and should NOT be used to determine
transaxle fluid level.
✽NOTICE
New automatic transaxle fluid should be
red. The red dye is added so the assem-
bly plant can identify it as automatic
transaxle fluid and distinguish it from
engine oil or antifreeze. The red dye,
which is not an indicator of fluid quali-
ty, is not permanent. As the vehicle is
driven, the automatic transaxle fluid
will begin to look darker. The colour
may eventually appear light brown.
Therefore, have an authorised
HYUNDAI dealer change the automatic
transaxle fluid according to the
Scheduled Maintenance at the begin-
ning of this section.
Use only the specified automatic
transaxle fluid. (Refer to “Recommended
lubricants and capacities” in section 8.)
Changing the automatic transaxle
fluid
Have automatic transaxle fluid changed
by an authorised HYUNDAI dealer
according to the Maintenance Schedule
at the beginning of this section.
WARNING - Transaxle fluid
The transaxle fluid level should be
checked when the engine is at nor-
mal operating temperature. This
means that the engine, radiator,
radiator hose and exhaust system
etc., are very hot. Exercise great
care not to burn yourself during
this procedure.
WARNING- Parking brake
To avoid sudden movement of the
vehicle, apply parking brake and
depress the brake pedal before
moving the shift lever.
CAUTION
• Low fluid level can cause poor
shifting gear. Overfilling can cause
foaming, loss of fluid and transaxle
malfunction.
• The use of a non-specified fluid
could result in transaxle malfunc-
tion and failure.
