Cold weather starting (flexible fuel vehicles only)
In cold weather, ethanol fuel distributors should supply winter grade
(E
d85) ethanol. If summer grade (Ed85) ethanol is used in cold weather,
you may experience increased cranking times, rough idle or hesitation
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.

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.
Trailer towing tips
• Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
• Allow more distance for stopping with a trailer attached.
• The trailer tongue weight should be 10–15% of the loaded trailer
weight.

OVERHEATING
If the temperature gauge indicates overheating and you experience
power loss, 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 the automatic transmission into P (Park) or the manual transmission into the neutral position, and apply the parking brake.
3. Turn off the air conditioner.
WARNING: 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.
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: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 damage your tires.
Temporary spare tire information (if equipped)
Your vehicle may be equipped with a conventional spare tire that may be
different in size (smaller diameter and narrower width) than other tires
on your vehicle. If this is the case, your spare tire is considered
“temporary” and the spare wheel will be labeled as such. Replace this
tire with a tire of the same size, speed rating and load carrying capacity
as the other road tires as soon as possible.

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.

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.
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.

Fill your engine coolant reservoir as outlined inAdding 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.
What you should know about Limp to Safety cooling (2.3L I4
engines only)
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily to a place of safety. The distance it can be driven
depends on ambient temperatures, vehicle load and terrain, so when the
engine drops into this mode, it is because the engine has overheated and
you need to take special care to avoid it shutting down.
