Overheating
▼Overheating
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
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 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 coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning indication is displayed:

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.
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 hood and start the
engine.

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.
6. Make sure the cooling fan is operating, then turn off the engine
after the temperature has
decreased.

▼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.
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.

When towing a FWD vehicle with the
rear wheels on the ground, release the
parking brake.
Refer to Electric Parking Brake (EPB) on
page 4-64.

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:
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.
CAUTION

Do not tow the vehicle pointed
backward with driving wheels on the
ground. This may cause internal
damage to the transmission.
Do not tow with sling-type
equipment. This could damage your
vehicle. Use wheel-lift or flatbed
equipment.

If the parking brake cannot be
released when towing the vehicle,
transport the vehicle with all front
and rear wheels raised off the ground
as shown in the figure. If the vehicle
is towed without raising the wheels
off the ground, the brake system
could be damaged.
1. Wheel dollies
Tiedown Hooks*
▼ Tiedown Hooks
CAUTION
Do not use the front and rear tiedown
eyelets for towing the vehicle.
They have been designed only for
securing the vehicle to a transport
vessel during shipping.
Using the eyelets for any other purpose
could result in the vehicle being
damaged.
1. Remove the tiedown eyelet and the
lug wrench from the luggage
compartment (page 7-3).
2. Wrap a flathead screwdriver or similar tool with a soft cloth to
prevent damage to a painted
bumper, and open the cap located
on the front or rear bumper.
