If your temperature gauge indicates  
overheating, you experience a loss  
of power, or hear loud pinging or  
knocking, the engine may be over-  
heating. If this happens, you should:  
WARNING  
WARNING  
While the engine is run-  
ning, keep hands,  
clothing and tools away  
from the moving parts  
such as the cooling fan  
and drive belt to pre-  
vent serious injury.  
NEVER remove the  
radiator cap or the  
drain plug while the  
engine and radiator are  
hot. Hot coolant and  
1.Pull off the road and stop as soon  
as it is safe to do so.  
2.Place the shift lever in P (Park, for  
Continuously Variable Transaxle  
vehicle) or neutral (for Manual  
Transaxle vehicle) and set the  
parking brake. If the air condition-  
ing is ON, turn it OFF.  
steam may blow out under pres-  
sure, causing serious injury.  
Turn the engine off and wait until  
the engine cools down. Use  
extreme care when removing the  
radiator cap. Wrap a thick towel  
around it, and turn it counterclock-  
wise slowly to the first stop. Step  
back while the pressure is  
released from the cooling system.  
When you are sure all the pres-  
sure has been released, press  
down on the cap, using a thick  
towel, and continue turning coun-  
terclockwise to remove it.  
4.Check for coolant leaking from the  
radiator, hoses or under the vehi-  
cle. (If the air conditioning had  
been in use, it is normal for cold  
water to be draining from it when  
you stop.)  
3.If engine coolant is running out  
under the vehicle or steam is com-  
ing out from the hood, stop the  
engine. Do not open the hood until  
the coolant has stopped running or  
the steaming has stopped. If there  
is no visible loss of engine coolant  
and no steam, leave the engine  
running and check to be sure the  
engine cooling fan is operating. If  
the fan is not running, turn the  
engine off.  
5.If engine coolant is leaking out,  
stop the engine immediately and  
we recommend that you call an  
authorized HYUNDAI dealer for  
assistance.  
!ꢀ!  
6.If you cannot find the cause of the  
overheating, wait until the engine  
temperature has returned to nor-  
mal. Then, if coolant has been lost,  
carefully add coolant to the reser-  
voir to bring the fluid level in the  
reservoir up to the halfway mark.  
NOTICE  
Serious loss of coolant indicates a  
leak in the cooling system and we  
recommend the system be  
checked by an authorized  
HYUNDAI dealer.  
• When the engine overheats from  
low engine coolant, suddenly  
adding engine coolant may cause  
cracks in the engine. To prevent  
damage, add engine coolant slow-  
ly in small quantities.  
7.Proceed with caution, keeping  
alert for further signs of overheat-  
ing. If overheating happens again,  
we recommend that you call an  
authorized HYUNDAI dealer for  
assistance.
