IF THE ENGINE OVERHEATS  
If your temperature gauge indicates  
overheating, you experience a loss of  
power, or hear loud pinging or knock-  
ing, the engine may be overheating. If  
this happens, you should:  
4. Check for coolant leaking from the  
radiator, hoses or under the vehicle.  
(If the air conditioning had been in  
use, it is normal for cold water to be  
draining from it when you stop.)  
1. Pull off the road and stop as soon as  
it is safe to do so.  
5. If engine coolant is leaking out, stop  
the engine immediately and we rec-  
ommend that you call a HYUNDAI  
authorised repairer for assistance.  
2. Place the shift lever in N (Neutral, for  
Automated manual transmission  
vehicle) or neutral (for Manual trans-  
mission vehicle) and set the parking  
brake. If the air conditioning is ON,  
turn it OFF.  
3. If engine coolant is running out under  
the vehicle or steam is coming out  
from the bonnet, stop the engine. Do  
not open the bonnet 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.  
WARNING  
NEVER remove the radia-  
tor cap or the drain plug  
whilst the engine and  
radiator are hot. Hot cool-  
ant and steam may blow  
out under pressure, 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 counterclockwise slowly  
to the first stop. Step back whilst the  
pressure is released from the cool-  
ing system. When you are sure all  
the pressure has been released,  
press down on the cap, using a thick  
towel, and continue turning counter-  
clockwise to remove it.  
WARNING  
Whilst the engine is run-  
ning, keep hands, cloth-  
ing and tools away from  
the moving parts such as  
the cooling fan and drive  
belt to prevent serious  
injury.
