Brake/Clutch Fluid
▼Inspecting Brake/Clutch Fluid Level
WARNING
If the brake/clutch fluid level is low, have
the brakes inspected:
A low brake/clutch
fluid level is dangerous.
A low level could indicate brake lining wear
or a brake system leak which could cause
the brakes to fail and lead to an accident.
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid leve l in the reservoir
regularly. It should be kept between the
MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is excessively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.
Window Washer Fluid
▼ Inspecting Washer Fluid Level
WA R N I N G
Use only windshield washer fluid or plain
water in the reservoir:
Using radiator antifreeze as washer
fluid is
dangerous. If sprayed on the windshield, it
will dirty the windshield, affect your
visibility, and could result in an accident.
Using Washer Fluid Without Anti-freeze
Protection in Cold Weather:
Operating your vehicle in temperatures
below 4 °C (40 °F) using washer fluid
without anti-freeze prot ection is dangerous
as it could cause impaired windshield
vision and result in an accident. In cold
weather, always use washer fluid with
anti-freeze protection.
NOTE
State or local regulations may restrict the
use of volatile organic compounds
(VOCs), which are commonly used as
anti-freeze agents in washer fluid. A
washer fluid with limited VOC content
should be used only if it provides adequate
freeze resistance for all regions and
climates in which the vehicle will be
operated.

Use only a Mazda-genuine tire valve cap:
Use of a non-genuine part is dangerous as
the correct tire air pressure cannot be
maintained if the tire valve becomes
damaged. If the vehicle is driven under this
condition, the tire air pressure will decrease
which could result in a serious accident. Do
not use any part for the tire valve cap that
is not a Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handlin g, and minimum tire
wear.
Refer to the specification charts (page
9-7).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.
▼ Tire Rotation
WA R N I N G
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining good
performance in handling and braking,
rotate the tires every 12,000 km (7,500
miles). However Mazda recommends to
rotate every 8,000 km (5,000 miles) to help
increase tire life and distribute wear more
evenly.
Refer to Scheduled Maintenance on page
6-4.

During rotation, inspect them for correct
balance.

Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:

Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel

tire. This tire should be used only for an
emergency and only for a short distance.

Use the temporary spare tire only until the
conventional tire is repaired, which should
be as soon as possible.
Refer to Tires on page 9-7.

CAUTION
Do not use your temporary spare tire rim
with a snow tire or a conventional tire.
Neither will properly fit and could
damage both tire and rim.
 The temporary spare tire has a tread life
of less than 5,000 km (3,000 miles). The
tread life may be shorter depending on
driving conditions.
 The temporary spare tire is for limited
use, however, if the tread wear
solid-band indicator appears, replace the
tire with the same type of temporary
spare (page 6-38).
NOTE
Tires degrade over time, even when they
are not being used on the road. It is
recommended that tires generally be
replaced when they are 6 years or older.
Heat caused by hot climates or frequent
high loading conditions can accelerate the
aging process. You should replace the
spare tire when you replace the other road
tires due to the aging of the spare tire. The
period in which the tire was manufactured
(both week and year) is indicated by a
4-digit number.
Refer to Tire Labeling on page 8-25.
▼ Replacing a Wheel
WA R N I N G
Always use wheels of the correct size on
your vehicle:
Using a wrong-sized wheel is dangerous.
Braking and handling could be
affected,
leading to loss of control and an accident.
CAUTION
A wrong-sized wheel may adversely affect:
 Tire fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration
 Headlight aim
 Bumper height
 Tire Pressure Monitoring System
*
NOTE
When replacing a wheel, make sure the
new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
For details, contact an Authorized
Mazda Dealer.

Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

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.
CAUTION
Use only a 12 V booster system. You can damage a 12 V starter, ignition system, and other
electrical parts beyond repair with a 24 V power supply (two 12 V batteries in series or a 24 V
motor generator set).
1. Move the booster vehicle so that its battery is as close as possible to your vehicle's battery.
2. Make sure that the power such as for the headlights and air conditioner is turned off.
3. Remove the battery cover.
4. Turn off the booster vehicle's engine and connect the jumper cables in the following
order.
Make sure that the jumper cables are securely connected so that they do not disconnect
due to engine vibrations.

Overheating
If 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.
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 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 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.
