1. Drive safely to the side of the road  
and park off the right-of-way.  
2. Put a vehicle with an automatic  
transmission in park (P), a manual  
transmission in neutral.  
If the engine coolant temperature  
gauge indicates overheating and the  
high engine coolant temperature  
warning indication is displayed, the  
vehicle loses power or you hear a loud  
knocking or pinging noise, the engine  
is probably too hot.

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.  
7. When cool, check the coolant level.  
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.

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.

Emergency Towing  
Towing an AWD vehicle with either the  
front or rear wheels on the ground is  
dangerous as the drive train could be  
damaged, or the vehicle could trail  
away from the tow truck and cause an  
accident. If the drive train has been  
damaged, transport the vehicle on a  
flatbed truck.  
Towing Description  
Towing Description  
We recommend that towing be done  
only by an Authorized Mazda Dealer  
or a commercial tow-truck service.  
Proper lifting and towing are necessary  
to prevent damage to the vehicle.  
Particularly when towing an AWD  
vehicle, where all the wheels are  
connected to the drive train, proper  
transporting of the vehicle is absolutely  
essential to avoid damaging the drive  
system. Government and local laws  
must be followed.  
CAUTION  
Do not tow the vehicle pointed  
backward with driving wheels on the  
ground. This may cause internal  
damage to the transmission.  
1. Wheel dollies  
A towed FWD vehicle should have its  
drive wheels (front wheels) off the  
ground. If excessive damage or other  
conditions prevent this, use wheel  
dollies.  
Do not tow with sling-type  
equipment. This could damage your  
vehicle. Use wheel-lift or flatbed  
equipment.  
When towing a FWD vehicle with the  
rear wheels on the ground, release the  
parking brake.  
Refer to Electric Parking Brake (EPB) on  
page 4-60.  
A towed AWD vehicle must have all its  
wheels off the ground.  
WARNING  
Always tow an AWD vehicle with all  
four wheels off the ground:
