Storage Compartments
WA R N I N G
Keep storage boxes closed when driving:
Driving with the storage boxes open is
dangerous. To reduce the possibility of
injury in an accident or a sudden stop, keep
the storage boxes closed when driving.
When loading cargo, make sure that it is
completely secured:
If the cargo is not completely secured, it
may move or collapse while driving or
during sudden braking, resulting in injury
or an accident.
Do not put articles in storage spaces with
no lid:
Putting articles in st orage spaces with no
lid is dangerous as they could be thrown
around the cabin if the vehicle is suddenly
accelerated and cause injury depending on
how the article is stored.
CAUTION
Do not leave lighters or eyeglasses in the
storage boxes while parked under the sun.
A lighter could explode or the plastic
material in eyeglasses could deform and

NOTE
Changing the coolant should be done by
an Authorized Mazda Dealer.
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.
SKYACTIV-G 2.5

SKYACTIV-G 2.5T

SKYACTIV-D 2.2

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.
