ENGINE COOLANT
Removing radiator
cap
•Never attempt to remove the
radiator cap while the engine
is operating or hot.
(Continued)
WARNING
(Continued)
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 while
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.
•Even if the engine is not oper-
ating, do not remove the radia-
tor cap or the drain plug while
the engine and radiator are
hot. Hot coolant and steam
may still blow out under pres-
sure, causing serious injury.
OAD075009
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 traveling
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.Checking the engine coolant

Maintenance
•Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
•Engine coolant can severely
obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control or damage to paint
and body trim.
WARNING
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-
minum engine parts and must be
protected by an phosphate based
ethylene-glycol 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.
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 authorized 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 generator.

*1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econ-
omy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure
in everyday driving, but in a year’s time, they can offer significant cost and energy savings.

3: If the ACEA A5 engine oil is not available in your country, you are able to use ILSAC GF-3 (or above) or ACEA A3 (or above).
*4: If the API service SM engine oil is not available in your country, you are able to use API service SL.
*5: If the ACEA C2 or C3, B4 engine oil is not available in your country, you are able to use API CH-4 (or above).
