If the tire is to be repaired or reused,
consult an Authorized Mazda
Dealer.
The wheel can be reused if the
sealant adhering to it is removed.
However, replace the valve with a
new one.

Changing a Tire
WA R N I N G
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 seriously injure someone.
No person should place any portion of their
body under a vehicle th at 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, le vel surface off the
right-of-way and firm ly set the parking
brake.
2. Put a vehicle with an automatic
transmission in Park (P), a manual
transmission in Reve rse (R) or 1, 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 and traffic.
5. Remove the jack and tool (page 7-3).
6. Block the wheel diagonally opposite the tire to be changed. When blocking
a wheel, place a tire block both in front
and behind the tire.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size if
possible to hold the tire in place.
▼Removing a Tire
WA R N I N G
When jacking-up a vehicle, always shift the
shift lever to 1st or R (manual transmission
vehicle) or shift the selector lever to P
(automatic transmission vehicle), apply the
parking brake, and place wheel blocks in
the position diagonally opposed to the
jack:
Changing a
flat tire without using wheel
blocks is dangerous because the vehicle
may move and fall off the jack even with
the shift lever in 1st or R, or the select lever
is in P, which could result in an accident.

Starting a Flooded Engine
If the engine fails to start, it may be
flooded (excessive fuel in the engine).

Follow this procedure:

1. If the engine does not start within 5seconds on the first try, wait 10
seconds and try again.
2. Make sure the parking brake is on.
3. Depress the accelerator all the way and hold it there.
4. Depress the clutch pedal (Manual transmission) or the brake pedal
(Automatic transmission), then press
the push button start. If the engine
starts, release the accelerator
immediately because the engine will
suddenly rev up.
5. If the engine fails to start, crank it
without depressing the accelerator.

If the engine still does not start using the
previous procedure, have your vehicle
inspected by an Authorized Mazda Dealer.
Push-Starting
Do not push-start your Mazda.
WA R N I N G
Never tow a vehicle to start it:
Towing a vehicle to start it is dangerous.
The vehicle being towed could surge
forward when its engine starts, causing the
2 vehicles to collide. The occupants could
be injured.
CAUTION
Do not push-start a vehicle that has a
manual transmission. It can damage the
emission control system.
NOTE
You cannot start a vehicle with an
automatic transmission by pushing it.

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 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 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 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.

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.
Government and local laws must be
followed.

A towed vehicle usually should have its
drive wheels (rear wheels) off the ground.
If excessive damage or other conditions
prevent this, use wheel dollies.
Wheel dollies

When towing with the rear wheels on the
ground, release the parking brake.
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.

▼Manual closing
Before closing manually
WA R N I N G
Verify that the ignition is switched
off
before manually operating the roof:
Manually closing the roof with the ignition
not switched off is dangerous as the
motors could turn on suddenly and cause
injury resulting from hands or fingers being
pinched in the mechanism.
1. Park on a hard, le vel surface off the
right-of-way and firm ly set the parking
brake.
2. Put a vehicle with an automatic transmission in Park (P), a manual
transmission in Neutral.
3. Switch the ignition off while
depressing the brake pedal.
4. Turn on the hazard w arning flasher if it
is needed.

 Because the clearance with the stored
front roof is narrow, be careful not to let
the L-shape hexagonal wrench contact
the roof when turning the bolt.
NOTE
Moving the seats as far forward as
possible and folding the seatbacks forward
will facilitate the procedure.
