Diesel Particulate Filter(SKYACTIV-D 2.2)
The diesel particulate filter collects and
removes most of the particulate matter
(PM) in the exhaust gas of a diesel engine.
PM collected by the diesel particulate
filter is cleared during normal driving,
however, PM may not be removed and the
diesel particulate filter indicator light may
illuminate under the following conditions:
If the vehicle is driven at 15 km/h (9
mph) or less continuously.
If the vehicle is repeatedly driven for a
short period of time (10 minute or less)
or driven while the engine is cold.
If the vehicle is idled for a long time.
When “DPF Clogged” is indicated
The particulate matter (PM) cannot be
removed automatically and the amount of
collected PM reaches a specified amount.
After the engine has sufficiently warmed
up (engine coolant temperature of 80 °C
(176 °F) or more), depress the accelerator
pedal and drive the vehicle at a speed of
20 km/h (12 mph) or more for about 15 to
20 minutes to eliminate the PM.
When “DPF malfunction” is indicated
Contact an Authorized Mazda Dealer.
CAUTION
If the vehicle continues to be driven with
“DPF Clogged” indicated in the display, the
particulate matter (PM) increases and the
indication may change to “DPF
malfunction”. If the indication changes to
“DPF malfunction”, have the vehicle
inspected immediately at an Authorized
Mazda Dealer. If the vehicle is not
inspected and continues to be driven, the
engine may malfunction.
NOTE
When “DPF malfunction” is indicated
in the display, the engine output is
restricted to protect the diesel
particulate filter.
The engine sound and exhaust gas smell
may change when PM is being removed
while driving.

Engine Coolant
▼Inspecting Coolant Level
WA R N I N G
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the engine has
been running, parts of the engine
compartment can become very hot. You
could be burned. Carefully inspect the
engine coolant in the coolant reservoir, but
do not open it.
Pull over to a safe location, then switch
the ignition off and make sure the fan is
not running before attempting to work
near the cooling fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if the
engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and radiator
are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot out
under pressure and cause serious injury.
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.

Rinse the wheels thoroughly with
lukewarm or cold water. Also, be sure to
clean the wheels after driving on dusty
or salted roads to help prevent
corrosion.
Avoid washing your vehicle in an
automatic car wash that uses high-speed
or hard brushes.
(19-inch wheel vehicle)
If your aluminum wheels lose luster,
apply wax which contains no polishing
powder.
▼ Plastic Part Maintenance
When cleaning the plastic lenses of the
lights, do not use
gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents or fluids using a
soft cloth immediately.
High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint.
Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage.
In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result in
deformation of plastic parts or paint
damage.
