Maintenance
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.
僅 Even if the engine is not operating, do
not remove the radiator cap or the
drain plug whilst the engine and radi-
ator are hot. Hot coolant and steam
may still blow out under pressure,
causing serious injury.
WARNING
The electric motor (cooling fan)
is controlled by engine coolant
temperature, 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 a rotating fan blades. As the
engine coolant temperature decreases,
the electric motor will automatically shut
off. This is a normal condition.
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 MAX and MIN (F and L) marks
Engine coolant ((petrol 1.0 MPI/1.0 FFV/1.2 MPI, Smartstream
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 MAX (F), but
do not overfill.
If frequent additions are required, have
the system inspected by a professional
workshop. Kia recommends to visit an
authorised Kia dealer/service partner.
Recommended engine coolant
僅 When adding coolant, use only deion-
ized water or soft water for your vehi-
cle and never mix hard water in the
coolant filled at the factory. An
improper coolant mixture can result in
serious malfunction or engine dam-
age.
僅 The engine in your vehicle has alumi-
num engine parts and must be pro-
tected by an ethylene-glycol with
phosphate based coolant to prevent
corrosion and freezing.
僅 DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
僅 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.
