Overheating  
If the temperature gauge indicates  
overheating or the high engine coolant  
temperature warning light turns on, the  
vehicle loses power, or you hear a loud  
knocking or pinging noise, the engine is  
probably too hot.  
1. Drive safely to the side of the road and  
park off the right-of-way.  
2. Shift into park (P).  
3. Apply the parking brake.  
4. Turn off the air conditioner.  
5. Check whether coolant or steam is  
escaping from the engine  
WARNING  
compartment.  
If steam is coming from the engine  
compartment:  
Do not go near the front of the vehicle.  
Stop the engine.  
Wait until the steam dissipates, then  
open the hood and start the engine.  
Pull over to a safe location, then switch  
the ignition off and make sure the fan is  
not running before attempting to work  
near the cooling fan:  
Working near the cooling fan when it is  
running is dangerous. The fan could  
continue running indefinitely even if the  
engine has stopped and the engine  
compartment temperature is high. You  
could be hit by the fan and seriously  
injured.  
If neither coolant nor steam is  
escaping:  
Open the hood and idle the engine  
until it cools.  
CAUTION  
If the cooling fan does not operate  
while the engine is running, the engine  
temperature will increase. Stop the  
engine and call an Authorized Mazda  
Dealer.  
Do not remove either cooling  
system cap when the engine and radiator  
are hot:  
When the engine and radiator are hot,  
scalding coolant and steam may shoot out  
under pressure and cause serious injury.  
6. Make sure the cooling fan is operating,  
then turn off the engine after the  
temperature has decreased.  
Open the hood ONLY after steam is no  
longer escaping from the engine:  
Steam from an overheated engine is  
dangerous. The escaping steam could  
seriously burn you.  
7. When cool, check the coolant level.

If it is low, look for coolant leaks from  
the radiator and hoses.  
CAUTION  
If the engine continues to overheat or  
frequently overheats, have the cooling  
system inspected. The engine could be  
seriously damaged unless repairs are  
made. Consult an Authorized Mazda  
Dealer.  
If you find a leak or other damage, or if  
coolant is still leaking:  
Stop the engine and call an Authorized  
Mazda Dealer.
