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.
