Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage).
Recycled engine coolant
Mazda Motor Corporation does NOT recommend the use of recycled
engine coolant in vehicles originally equipped with Mazda Premium Gold
Engine Coolant since a Mazda-approved recycling process is not yet
available.
Used engine coolant should be disposed of in an appropriate
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 Maintenance product specifications and capacities in this chapter.
Fill your engine coolant reservoir as outlined in Adding engine coolant
in this section.
Severe climates
If you drive in extremely cold climates (less than –34°F [–36°C ]):
• 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.
FUEL FILTER
For fuel filter replacement, see your authorized dealer. Refer to
scheduled maintenance information for the appropriate intervals for
changing the fuel filter.
Replace the fuel filter with an authorized Mazda part. The
customer warranty may be void for any damage to the fuel system
if an authorized Mazda fuel filter is not used.
WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS
Important safety precautions
WARNING: Do not overfill the fuel tank. The pressure in an
overfilled tank may cause leakage and lead to fuel spray and
fire.
WARNING: The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap.
Otherwise, fuel may spray out and injure you or others.
WARNING: If you do not use the proper fuel filler cap,
excessive vacuum in the fuel tank may damage the fuel system
or cause the fuel cap to disengage in a collision, which may
result in possible personal injury.
WARNING: Automotive fuels can cause serious injury or death
if misused or mishandled.

MERCON V ATF.4Fill to 1/4 inch to 9/16 inch (6mm to 14mm) below bottom of fill hole.54WD vehicles exposed for prolonged periods to temperatures less than -40° C (-40° F) should
change out the rear axle fluid to SAE 75W-140 axle lubricant.6The Power Transfer Unit is lubricated for life with synthetic lube. Lubricant levels are not to be
checked or changed unless a leak is suspected or repair required. Replace Power Transfer Unit
lubricant with specified synthetic lubricant anytime the unit is submerged in water.
