Maintenance and Care
Owner Maintenance
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year—at the beginning of the
winter season—and before traveling where
temperatures may drop below freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the F and L marks
on the coolant reservoir when the engine
is cool.
If it is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Securely tighten the coolant reservoir tank
cap after adding coolant.

Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WARNING
Do not install the temporary spare tire
on the front wheels (driving wheels): Driving with the temporary spare tire
on one of the front driving wheels is
dangerous. Handling will be aff ected.
You could lose control of the vehicle,
especially on ice or snow bound roads,
and have an accident. Move a regular
tire to the front wheel and install the
temporary spare tire to the rear.
CAUTION
