Flat Tire
NOTE
 If an emergency flat tire repair has been
performed using the emergency flat tire
repair kit, Mazda recommends that the
tire be replaced with a new one as soon
as possible. 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.
Mexico
1. Move the vehicle off the right-of-way
to a safe place on a level and hard
surface where the vehicle does not
obstruct traffic.
2. Shift the shift lever to the 1 or Reverse
(R) position for a manual transmission,
and shift the selector lever to the P
position for an automatic transmission.
3. Apply the parking brake with the brake
pedal depressed and turn off the engine.
4. If necessary, flash the hazard warning
lights and set up the roadside
emergency triangle.
5. Unload passengers and cargo and
remove the emergency flat tire repair
kit.
6. Shake the tire sealant well.
CAUTION
If the bottle is shaken after the
injection hose is screwed on, tire
sealant could spray out from the
injection hose. Tire sealant contacting
clothing or other objects may be
impossible to remove. Shake the bottle
before screwing on the injection hose.
NOTE
The sealant hardens easily and injecting
it will be difficult under cold weather
conditions (0 °C (32 °F) or below). Warm
the sealant inside the vehicle to facilitate
injection.
7. Remove the cap from the bottle. Screw
on the injection hose with the bottle's
inner cap left on to break the inner cap.

Locking Lug Nuts*
If your vehicle has Mazda optional
antitheft wheel lug nuts, one on each
wheel will lock the tires and you must
use a special key to unlock them. This
key will attach to the lug wrench.
Register them with the lock manufacturer
by filling out the card provided in the
glove compartment and mailing it in the
accompanying envelope. If you lose this
key, consult an Authorized Mazda Dealer
or use the lock manufacturer's order form,
which is with the registration card.
Accessory wheel locks cannot be used on
steel wheels. This includes situations when
the spare tire is installed. If the spare tire
is installed, one of the original lug nuts
(which should still be in the vehicle) must
be installed in place of the wheel lock.
Special ke y
Antitheft lug nut
To remove an antitheft lug nut
1. Obtain the special key for the antitheft
lug nut.
2. Place the special key on top of the
antitheft lug nut, and be sure to hold
the key square to it. If you hold the key
at an angle, you may damage both key
and nut. Do not use a power impact
wrench.
3. Place the lug wrench on top of the key
and apply pressure. Turn the wrench
counterclockwise.

Jump-Starting
Jump-starting is dangerous if done incorrectly. So follow the procedure carefully. If you
feel unsure about jump-starting, we strongly recommend that you have a c\
ompetent service
technician do the work.
WARNING
Follow These Precautions Carefully:
To ensure safe and correct handling of the battery, read the following precautions
carefully before using the battery or inspecting it.
Do not allow the positive () terminal to contact any other metal object that
could cause sparks: Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced
during normal battery operation, could ignite and cause the battery to explode. An
exploding battery can cause serious burns and injuries. When working near a battery, do
not allow metal tools to contact the positive (
) or negative () terminal of the battery.
Keep all flames, including cigarettes, and sparks away from open battery cells:
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced
during normal battery operation, could ignite and cause the battery to explode. An
exploding battery can cause serious burns and injuries.
Do not jump-start a frozen battery or one with a low fluid level: Jump-starting a frozen battery or one with a low fluid level is dangerous. It may rupture
or explode, causing serious injury.
Connect the negative cable to a good ground point away from the battery: Connecting the end of the second jumper cable to the negative (
) terminal of the
discharged battery is dangerous.
A spark could cause the gas around the battery to explode and injure someone.
Route the jumper cables away from parts that will be moving: Connecting a jumper cable near or to moving parts (cooling fans, belts) is dangerous. The
cable could get caught when the engine starts and cause serious injury.

Emergency Starting
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
five seconds on the first try, wait ten
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.

the above procedure, have your vehicle
inspected by an Authorized Mazda Dealer.
Push-Starting
Do not push-start your Mazda.
WARNING
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 two 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.

If Trouble Arises
Overheating
Overheating
If the high engine coolant temperature
warning light illuminates, 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 high engine coolant temperature
warning light illuminates:
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.
7. When cool, check the coolant level.
If it is low , look for coolant leaks from
the radiator and hoses.
