FULL
LOW
If it is at or near LOW, add enough
coolant to the coolant reservoir to
provide freezing and corrosion
protection and to bring the level to
FULL.
Securely tighten the coolant reservoir
tank cap after adding coolant.
CAUTION
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
If the “FL22” mark is shown on or
near the cooling system cap, use of
FL-22 is recommended when
replacing engine coolant. Using
engine coolant other than FL-22 may
cause serious damage to the engine
and cooling system.
If the coolant reservoir is empty or new
coolant is required frequently, consult
an Authorized Mazda Dealer.
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 level 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.

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 fr om 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 dama ge 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 th e 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 se curely connected so that they do not
disconnect due to engine vibrations.

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 isoperating, 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.

If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required
(page 6-19).
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.

WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light turns
on or flashes:
Driving the vehicle at high speeds
while the TPMS warning light is turned
on or flashing is dangerous because
the brake performance and the
steering wheel operability will be
reduced. If the vehicle is driven at high
speeds or the brakes are suddenly
applied, it could lead to an accident.
Gradually apply the brakes to lower the
vehicle's speed.
Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to drive the vehicle while
ignoring the illumi nation/flashing of
the TPMS warning light is dangerous
because a tire may burst which could
lead to an accident. Take appropriate
measures as soon as possible.
NOTE
While the TPMS is learning the tire
positions, such as immediately after a
tire position has been changed, the tire
pressure at the tire position prior to it
being changed is displayed until the
system completes the learning. For this
reason, the tire pressures displayed for
the tire positions may be different from
the actual tire pressures at the tire
positions.
Action to be taken
Adjust the tire pressures to the
appropriate pressures.
Refer to Tire Inflation Pressure on page
6-33.
CAUTION
Adjust the tire pressures while the
tires are cool. Because the air
pressure in the tires fluctuates
depending on the temperature,
before adjusting the tire pressures,
let the vehicle sit for an hour or drive
it only within a 1.6 km (1 mile)
distance. If the tire pressures are
adjusted while the tires are warm,
the tire pressures may decrease
below the
specified air pressure after
cooling down which could turn on
the warning light. In addition,
because the air pressure in the tires
decreases when the ambient
temperature is low, if the ambient
temperature increases, an
illuminated TPMS warning light may
turn off. Under any circumstances,
always adjust the tire pressures while
the tires are cool.
After adjusting the tire pressures, the
TPMS warning light turns off. If the
TPMS warning light does not turn
off,
drive the vehicle at a speed of about
25 km (16 mph) or faster for 3
minutes or longer and make sure the
warning light turns off.
If the TPMS warning light remains on
even after adjusting the tire pressures,
one of the tires may have a puncture.
