position. If the brake system warning light does not illuminate at this
time, seek service immediately from your dealership. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your servicing dealership.WARNING: Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the
vehicle. Have the vehicle checked by your dealer immediately.
Anti-lock brake system: If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.
Air bag readiness: If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also
sound when a malfunction in the supplemental restraint system has been
detected.
Safety belt: Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt. Refer to the Seating
and safety restraints chapter.
Charging system: Illuminates when
the battery is not charging properly.
Check gage: Illuminates when any
of the following conditions has
occurred:
• The engine coolant temperature
is high.
• The engine oil pressure is low.

until the engine has warmed up. Consult your fuel distributor for the
availability of winter grade (E
d85) ethanol. High-quality blends of winter
grade (E
d85) ethanol will produce satisfactory cold weather starting and
driving results.
Cold starting performance can also be improved by using an engine block
heater. Engine block heaters are available as an option and can be
obtained from your Mazda dealer. Consult the engine block heater
section for proper use of the engine block heater.
If you experience cold weather starting problems on (E
d85) ethanol, and
neither an alternative brand of (E
d85) ethanol nor an engine block
heater is available, adding unleaded gasoline to your tank will improve
cold starting performance. Your vehicle is designed to operate on (E
d85)
ethanol, unleaded gasoline alone, or any mixture of the two.
If the engine fails to start using the preceding instructions (flexible
fuel vehicles only)
1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then crank the engine.
2. When the engine starts, release the key, then gradually release the accelerator pedal as the engine speeds up. If the engine still fails to
start, repeat Step 1.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant which aids in starting
and heater/defroster performance. 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. The heater can be plugged in the
night before starting the vehicle. WARNING: To reduce the risk of electrical shock, do not use
your heater with ungrounded electrical systems or two-pronged
(cheater) adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.

Driving while you tow
When towing a trailer:
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Consult your local motor vehicle speed regulations for towing a trailer.
• To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5–speed automatic transmission section in this
chapter.
• Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gauge in theInstrument cluster
chapter.
• Anticipate stops and brake gradually.
• Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your service maintenance section for
more information.

4. Check whether coolant or steam is escaping from under the hood orfrom the engine compartment.
• If steam is coming from the engine compartment:do not 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 does not lower the temperature, stop
the engine and let it cool.
5. Check the coolant level. If it is 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.
See Adding coolant in theMaintenance and specifications section. If
you find no problems, the engine is cool and no leaks are obvious,
carefully add coolant as required.
WARNING: When the engine and radiator are hot, scalding
coolant and steam may shoot out under pressure and cause
serious injury. Do not remove the cooling system cap when the
engine and radiator are hot.
Note: If the engine continues to overheat or frequently overheats, have
the cooling system inspected. The engine could be seriously damaged
unless repairs are made.
CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
WARNING: The use of tire sealants is not recommended and
may compromise the integrity of your tires.

WINDSHIELD WASHER FLUID
Windshield washer fluid
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets Mazda specification . Refer to
Lubricant specificationsin this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
WARNING: If you operate your vehicle in temperatures below
4.5° C (40° F), use washer fluid with antifreeze protection.
Failure to use washer fluid with antifreeze protection in cold
weather could result in impaired windshield vision and increase
the risk of injury or accident.
Note: Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.

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.
A 50/50 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.

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.
