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 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  
recommend that you call a HYUNDAI  
authorised repairer for assistance.  
2. Place the shift lever in P (Park, for  
automatic transmission/dual clutch  
transmission vehicle) or neutral (for  
manual transmission/dual clutch  
transmission 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 radiator  
cap or the drain plug whilst  
the engine and radiator are  
hot. Hot coolant 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 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.  
WARNING  
Whilst the engine is  
running, keep hands,  
clothing and tools away  
from the moving parts such  
as the cooling fan and drive  
belt to prevent serious  
injury.

Emergency situations  
6.If you cannot find the cause of the  
overheating, wait until the engine  
temperature has returned to normal.  
Then, if coolant has been lost,  
carefully add coolant to the reservoir  
to bring the fluid level in the reservoir  
up to the halfway mark.  
7. Proceed with caution, keeping alert  
for further signs of overheating.  
If overheating happens again, we  
recommend that you call a HYUNDAI  
authorised repairer for assistance.
