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 iscool. 
If the coolant level is low, add enough 
specified coolant to provide protection 
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent 
additions are required, see an authorized 
HYUNDAI dealer for a cooling systeminspection.

(Continued) 
 Turn the engine off and wait untilit 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 operat- ing, do not remove the radiator cap or the drain plug while the 
engine and radiator are hot. Hot 
coolant and steam may still blow
out under pressure, causing seri- 
ous injury.WARNING 
The electric motor (cooling fan) is con-
trolled by engine
coolant temperature, 
refrigerant pressure
and vehicle speed. It may some- 
times 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 tem- 
perature decreases, the electric
motor will automatically shut off. This is a normal condition.

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.

WASHER FLUID
Checking the washer fluid level  
Check the fluid level in the washer fluid 
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not 
available. However, use washer solvent 
with antifreeze characteristics in cold cli-
mates to prevent freezing.
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.
 Windshield washer fluid agents contain some amounts of alcohol 
and can be flammable under cer- 
tain circumstances. Do not allow sparks or flame to contact thewasher fluid or the washer fluid 
reservoir. Damage to the vehicle 
or occupants could occur.
 Windshield washer fluid is poi- sonous to humans and animals. 
Do not drink and avoid contacting 
windshield washer fluid. Serious
injury or death could occur.
