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.
NOTE
• Only the trip meters record tenths of
kilometers (miles).
• The trip record will be erased when;

The power supply is interrupted
(blown fuse or the battery is
disconnected).
 The vehicle is driven over 999.9
km (mile).
Don ’t run the engine with the
tachometer needle in the RED ZONE.
This may cause severe engine damage.
Red zone
CAUTION
Driving with an overheated engine
can cause serious engine damage
(page 7-11).

Overheating
If the temperature gauge indicates
overheating, the vehicle loses power, or
you hear a loud knocking or pinging
noise, the engine is probably too hot.
If the temperature gauge indicates
overheating: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.
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.
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.
5. Make sure the cooling fan is operating, then turn off the engine after the
temperature has decreased.
Overheating
Cooling Fan and Engine
Inspection:
Inspecting the engine with the
ignition switch in the ON position is
dangerous. The cooling fan could
turn on unexpectedly even when the
engine isn ’t running. You could be
seriously injured by the fan. Turn the
ignition switch off and remove the key
from the ignition switch when you
inspect the engine.
Cooling System Cap:
When the engine and radiator are
hot, scalding coolant and steam may
shoot out under pressure and cause
serious injury. Don ’t remove the
cooling system cap when the engine
and radiator are hot.
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.
WARNING
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.

*1 Also inspect and adjust the power steering and air conditioner drive belts, if installed.
*2 Replacement of the timing belt is required at every 100,000 km {62,500 miles}. Failure to replace the timing belt may result in damage to the engine.
*3 If the vehicle is operated under any of the following conditions, change the engine oil and oil filter more often than recommended intervals.
a) Driving in dusty conditions.
b) Extended periods of idling or low speed operation.
c) Driving for long period in cold temperatures or driving regularly at short distance only.
*4 If the vehicle is operated in very dusty or sandy areas, inspect and if necessary, clean or replace the air filter more often than the recommended intervals.

Maintenance and Care
Owner Maintenance
Form No. 8S15-EA-03G
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.
If it ’s at or near LOW, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to FULL.
Do not overfill.
If new coolant is required frequently,
consult an Authorized Mazda Dealer.
Changing Coolant
Change coolant according to Scheduled
Maintenance (page 8-3).
For mixture percentage:
Radiator coolant will damage paint.
Rinse it off quickly.
CAUTION
• Use only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolant
’s effectiveness.
• Don
’t add only water. Always add a
proper coolant mixture.
• The engine has aluminum parts and
must be protected by an ethylene-
glycol-based coolant to prevent
corrosion and freezing.
• DO NOT USE alcohol or methanol
antifreeze. DO NOT MIX alcohol
or methanol with the coolant. This
could damage the cooling system.
• Don
’t use a solution that contains
more than 60 % antifreeze.
This would reduce effectiveness.

Maintenance and Care
Owner Maintenance
Form No. 8S15-EA-03G
To change coolant
1. Remove the cooling system cap.
2. Only when the engine is cool, remove the radiator drain plug and drain the
coolant into a suitable container.
Properly dispose of the used coolant.
3. Flush out the system with running water. 4. Drain the system completely. Insert
and tighten the plug. Add as much
ethylene-glycol-based coolant and
water as necessary to provide freezing
and corrosion protection.
5. In extremely cold climates, add the amount recommended in the coolant
manufacturer ’s instructions.
6. Run the engine at idle with the cooling system cap off. Slowly add additional
coolant if necessary.
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.
Removing the Cooling System Cap:
Removing the cooling system cap
while the engine is running or hot is
dangerous. This might lead to cooling
system and engine damage and could
result in serious injury from escaping
hot coolant or steam. Turn off the
engine and wait until it ’s cool. Even
then, be very careful when removing
the cap. Wrap a thick cloth around
the cap and slowly turn it
counterclockwise to the first stop.
Step back while the pressure escapes.
When you ’re sure all the pressure is
gone, press down on the cap — still
using a cloth — turn the cap, and
remove it.
