3WARNING  
Removing the radiator cap while the  
engine is hot can cause the coolant to spray  
out, seriously scalding you.  
2. Once the engine has cooled down, inspect  
the coolant level and check the cooling  
system components for leaks.  
u If the coolant level in the reserve tank is  
low, add coolant until it reaches the  
MAX mark.  
u If there is no coolant in the reserve tank,  
check that the radiator is cool. Cover the  
radiator cap with a heavy cloth and open  
the cap. If necessary, add coolant up to  
the base of the filler neck, and put the  
cap back on.  
Always let the engine and radiator cool  
down before removing the radiator cap.
