should turn off. (A driving cycle consists of a cold engine startup
followed by mixed city/highway driving.) No additional vehicle service is
required.
If the light remains on, have your vehicle serviced at the first available
opportunity.
NOTE:The
CHECK
ENGINElight will illuminate if vehicle refueling is conducted
with the engine running.
WARNING: Never refuel vehicle with the engine running.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity. WARNING: Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components,
possibly causing a fire.
Check gage
Illuminates when the engine coolant
temperature is high, the engine oil
pressure is low or the fuel gauge is
at or near empty. Refer to Engine
coolant temperature gauge, Engine oil pressure gauge orFuel gauge
in this chapter for more information.
Brake system warning
To confirm the brake system
warning light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position
(alternatively for some vehicles
when the ignition is moved from the ON position to START position, the
light will momentarily illuminate prior to reaching the START position).
It also illuminates if the parking brake is engaged. If the brake system
warning light does not illuminate as described, seek service immediately.
Illumination after the parking brake is released indicates low brake fluid

GAUGES
Engine coolant temperature gauge
Indicates the temperature of the
engine coolant. At normal operating
temperature, the needle remains
within the normal area (the area
between the “H” and “C”).
If it enters the red section, the
engine is overheating. Stop the
vehicle as soon as safely
possible, switch off the engine
immediately and let the engine cool.
Refer toEngine coolant in theMaintenance and specifications
chapter.
WARNING: Never remove the coolant reservoir cap and/or the
radiator cap while the engine is running or hot, this may result
in serious burns.
NOTE: This gauge indicates the temperature of the engine coolant, not
the coolant level. If the coolant is not at its proper level the gauge
indication will not be accurate.

If you should experience cold weather starting problems on (Ed85)
ethanol, and neither an alternative brand of (E
d85) ethanol nor an
engine block heater is available, the addition of unleaded gasoline to your
tank will improve cold starting performance. Your vehicle is designed to
operate on (E
d85) ethanol alone, unleaded gasoline alone, or any mixture
of the two.
If the engine fails to start using the preceding instructions
1. Press the accelerator pedal 1/3 to 1/2 way to floor and hold.
2. Turn the key to START position.
3. When the engine starts, release the key, then release the accelerator pedal gradually as the engine speeds up.
4. If the engine still fails to start, repeat steps one through three.
5. After the engine starts, hold your foot on the brake pedal, put the gearshift lever in gear and release the parking brake. Slowly release
the brake pedal and drive away in a normal manner.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant, which improves
starting, warms up the engine faster and allows the heater-defroster
system to respond quickly. Use of an engine block heater is strongly
recommended if you live in a region where temperatures reach -23° C
(-10° F) or below.
For best results, plug the heater in at least three hours before starting
the vehicle. Using the heater for longer than three hours will not harm
the engine, so the heater can be plugged in the night before starting the
vehicle. WARNING: To prevent electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is present in exhaust
fumes. Take precautions to avoid its dangerous effects.

1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift lever in P (Park), turn off all accessories and startthe engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
• The vehicle may need to be driven to relearn the idle and fuel trim
strategy.
• If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
When the battery is disconnected or a new battery installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
• Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
ENGINE COOLANT
Checking engine coolant
Your engine’s cooling system has been factory-filled with a 50/50 mixture
of distilled water and Mazda Genuine Engine Coolant, or an equivalent
premium engine coolant that meets Mazda specification.

A50/50 mixture of distilled water and Mazda Genuine Engine Coolant
provides:
• maximum cooling system efficiency.
• freeze protection down to -36° C (-34° F).
• boiling protection up to 129° C (265° F).
• protection against rust and other forms of corrosion.
• an accurate temperature readout from the engine coolant
gauge.
The engine coolant must be maintained at the correct fluid level
and concentration to work properly. If the engine coolant fluid
level and concentration is not maintained correctly, damage to
the engine and cooling system may result.

Always dispose of used automotive fluids in a responsible manner.
Follow your community’s regulations and standards for recycling and
disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
to Refill capacities in this chapter.
Fill your engine coolant reservoir as outlined in Adding engine coolant
in this chapter.
Severe climates
If you drive in extremely cold climates (less than –36° C [–34° F]):
• It may be necessary to increase the coolant concentration
above 50%.
• NEVER increase the coolant concentration above 60%.
• Increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.
• Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
freeze protection at the temperatures in which you drive in the
winter months.
If you drive in extremely hot climates:
• It is still necessary to maintain the coolant concentration
above 40%.
• NEVER decrease the coolant concentration below 40%.
• Decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.
• Decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
• Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.

CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid.
Refer to the service maintenance
section for the service interval
schedules. If adding fluid is
necessary, use only MERCONAT F.
1. Start the engine and let it run until it reaches normal operating temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several times.
3. Turn the engine off.
4. If your vehicle is equipped with a 3.0L V6 engine, check the
fluid level on the dipstick. It should be within the FULL HOT range.
Do not add fluid if the level is within this range.
5. If your vehicle is equipped with a 4.0L SOHC V6 or 2.3L I4
engine, check the fluid level in the reservoir. It should be between
the MIN and MAX lines. Do not add fluid if the level is within this
range.
6. If the fluid is low, add fluid in small amounts, continuously checking the level until it reaches the FULL HOT range. Be sure to put the
dipstick back in the reservoir.
