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.
WA R N I N G
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.
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.
Open the bonnet 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 temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on:
1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic transaxle in park (P), a manual
transaxle in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is escaping from the engine
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 bonnet and start the engine.
If neither coolant nor steam is
escaping:
Open the bonnet 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 expert repairer, we
recommend an Authorised Mazda
Repairer.
6. Make sure the cooling fan is operating, then turn off the engine after the
temperature has decreased.

This could damage your vehicle. Use
wheel-lift or
flatbed equipment.
If the electric parking brake (EPB) cannot
be released when towing the vehicle,
transport the vehicle with all front and
rear wheels raised
off the ground as

damaged.
Wheel dollies
If towing service is not available in an
emergency, the vehicle may be towed with
all four wheels on the ground using the
towing hook at the front of the vehicle.
Only tow the vehicle on paved surfaces for
short distances at low speeds.
CAUTION
Follow these instructions when towing the
vehicle with all wheels on the ground.
1. Shift to neutral (Manual transaxle), or the N position (Automatic transaxle).
2. Switch the ignition to ON.
3. Release the parking brake.
Refer to Electric Parking Brake (EPB) on
