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 aluminum engine parts and must be protected by
an ethylene-glycol-based coolant to pre-
vent corrosion and freezing.
 DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
 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 authorized 
HYUNDAI dealer according to theMaintenance Schedule at the beginningof 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.
OLM079007
CAUTION
Put a thick cloth around the radiator cap before refilling the coolant inorder to prevent the coolant from
overflowing into engine parts suchas 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 windshield and may cause 
loss of vehicle control or damage 
to paint and body trim.
