Tachometer
The tachometer shows engine speed in
thousands of revolutions per minute
(rpm).

Engine Coolant Temperature
Gauge
The engine coolant temperature gauge
shows the temperature of the engine
coolant.If the needle exceeds normal range toward
H, it indicates overheating.

Fuel Gauge
The fuel gauge shows approximately how
much fuel is in the tank. We recommend
keeping the tank over 1/4 full. When the
low fuel warning light illuminates or
when the needle is near E, refuel as soon
as possible.
Don’t run the engine with the
tachometer needle in the RED ZONE.
This may cause severe engine damage.

Overheating
If the temperature gauge indicates
overheating, you experience power loss,
or you hear a loud knocking or pinging
noise, the engine is probably too hot.
If this happens:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Shift into park (P) .
Apply the parking brake.
3. Turn off the air conditioner.
4. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment:
Don’t go near the front of the vehicle.
Stop the engine. Then turn the ignition
switch to the ON position without
starting the engine.
The radiator cooling fans will start to
cool the engine.
If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools. If this doesn’t lower the
temperature, stop the engine and let it
cool.5. Check the coolant level.
If it’s low, look for leaks in the radiator
hoses and connections, heater hoses
and connections, radiator, and water
pump.
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 8-12).
Overheating
Steam from Overheated Engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you. Open the hood
ONLY after steam is no longer
escaping from the engine.

3. Replace the plug tightly after the oil
has thoroughly drained.
4. Fill the engine with new oil to the F
mark on the dipstick.
5. Securely replace the oil-filler cap.
6. Start the engine and inspect around the
drain plug for leaks.
7. Turn it off and wait 5 minutes for the
oil to return to the oil pan.
Check the oil level and fill to the F mark if
necessary.
Oil capacity (General reference only,
refer to Specifications section for
capacities.)
Changing oil filter
Because you need a special tool to
retighten the filter, an Authorized Mazda
Dealer should do the work.

Inspecting Coolant Level
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year—at the beginning of the
winter season—and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the FULL and LOW
marks on the coolant reservoir when the
engine is cool.
NOTE
•The indicated engine oil capacities
are for general reference purposes
only. When adding or changing oil,
verify the engine oil level with the
oil dipstick.
•Use only specified engine oil (page
10-4).
Engine Coolant
Hot Engine:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Don’t
inspect the coolant system or add
coolant when the engine is hot.

7. At this point, wait until the engine
reaches normal operating temperature;
then depress the accelerator two or
three times. Add more coolant, if
necessary, until the system is full.
8. Install the cooling system cap. Inspect
all connections for leaks. Inspect the
level in the coolant reservoir one more
time.

Inspecting Brake Fluid Level
Inspect the fluid level in the reservoir
regularly. It should be kept at MAX.
The level normally drops with
accumulated distance, a condition
associated with wear of brake linings. If it
is excessively low, have the brake system
inspected by an Authorized Mazda
Dealer.
