What to do in an emergency  
IF THE ENGINE OVERHEATS  
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  
NEVER remove the  
running, keep hands,  
clothing and tools  
away from the mov-  
ing parts such as the  
cooling fan and drive  
belt to prevent seri-  
ous injury.  
radiator cap or the  
drain plug while the  
engine and radiator  
are hot. Hot coolant  
and steam may blow out under  
pressure, causing serious  
injury.  
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  
automatic transaxle vehicle) or  
neutral (for manual transaxle vehi-  
cle) and set the parking brake. If  
the air conditioning is ON, turn it  
OFF.  
Turn the engine off and wait  
until the engine cools down.  
Use extreme care when remov-  
ing 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 counterclock-  
wise 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.  
CAUTION  
Serious loss of coolant indi-  
cates a leak in the cooling  
system and we recommend  
the system be checked by an  
authorized HYUNDAI dealer.  
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.  
When the engine overheats  
from low engine coolant, sud-  
denly adding engine coolant  
may cause cracks in the  
engine. To prevent damage,  
add engine coolant slowly in  
small quantities.
