Ta k i n g A c t i o n w i t hOverheating
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning light 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 vehicle power 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.

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
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.
7. When cool, check the coolant level. If it is low, look for coolant leaks
from the radiator and hoses.

If you find a leak or other damage, or
if coolant is still leaking:
Stop the engine and call an Authorized
Mazda Dealer.
1. Cooling system cap
2. Coolant reservoir
3. Cooling fan
4. Radiator
If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required
(page 9-14).
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.

could indicate a flat tire.
Steering becomes difficult.The vehicle begins to vibrate
excessively.
The vehicle pulls in one direction.
If you have a flat tire, drive slowly to a
level spot that is well off the road and
out of the way of traffic to change the
tire.
Stopping in traffic or on the shoulder
of a busy road is dangerous.
WARNING
Do not install the temporary spare tire
on the rear wheels (driving wheels).
Driving with the temporary spare tire
on one of the rear driving wheels is
dangerous. Handling will be affected.
You could lose control of the vehicle,
especially on ice or snow bound roads,
and have an accident. Move a regular
tire to the rear wheel and install the
temporary spare tire to the front.
Be sure to follow the directions for
changing a tire.
Changing a tire is dangerous if not
done properly. The vehicle can slip off
the jack and seriou sly injure someone.
No person should place any portion of
their body under a vehicle that is
supported by a jack.
Never allow anyone inside a vehicle
supported by a jack.
Allowing someone to remain in a
vehicle supported by a jack is
dangerous. The occupant could cause
the vehicle to fall resulting in serious
injury.
NOTE
Make sure the jack is well lubricated
before using it.
1. Park on a hard, level surface off the
right-of-way and firmly set the
parking brake.
2. Shift into Park (P) and turn off the
engine.
3. Turn on the hazard warning flasher.
4. Have passengers get out of the
vehicle and away from the vehicle

shift the selector lever to P position,
apply the parking brake, and place
wheel blocks in the position
diagonally opposed to the jack.

wheel blocks is dangerous because the
vehicle may move and fall off the jack
even with the selector lever is in P
position, which could result in an
accident.
1. Loosen the lug nuts by turning them counterclockwise one turn each,
but do not remove any lug nuts
until the tire has been raised off the
ground.
NOTE
If your Mazda is equipped with the
optional antitheft wheel lug nuts, a
special key must be used to unlock
the locking lug nut for each wheel.
For details, refer to “Locking Lug
Nuts” below.
2. Place the jack on the ground.
3. Turn the jack screw in the direction shown in the figure and adjust the
jack head so that it is close to the
jack-up position.
4. Place the jack under the jack-upposition closest to the tire being
changed with the jack head
squarely under the jack-up point.
5. Continue raising the jack headgradually by rotating the screw with
your hand until the jack head is
