I. TECHNICAL FEATURES
Common Rail Injection System
1. The common rail fuel injection system stores fuel pressurized by the supply pump in
the common rail and injects fuel into each cylinder using fuel injectors based on
control from the PCM.
2. Fuel is atomized by extremely high fuel injection pressure and the generation of
particulate matter (PM) is reduced by the dissipation of unburnt fuel.
3. There is a high degree of flexibility in the fuel injection amount, fuel injection timing
and fuel injection pattern. NOx/PM is reduced by controlling the fuel conditions
based on vehicle conditions.
MGSS:
COMMON RAIL
INJECTION
SYSTEM
[SKYACTIV-D

Diesel Particulate Filter (DPF)
1. Diesel particulate elimination equipment (DPF) has been adopted to eliminate PM
from the exhaust gas.
2. When the amount of accumulated particulate matter (PM) in the diesel particulate
filter exceeds a certain value, the PCM acts to combust and eliminate the PM.

Before Driving
▼Fuel Requirements
The vehicle will operate efficiently on diesel fuel with specification Ultra-Low Sulfur Diesel
(ULSD, 15 ppm sulfur or less) fuel that meets the ASTM D975 standard or the equivalent.
Fuel grade labels are visible on the fuel-filler lid, therefore, always verify the fuel grade
before refueling. If the fuel grade cannot be verified, ask the gas station attendant.
CAUTION:
1. Never use fuel other than specification Ultra-Low Sulfur Diesel (ULSD, 15 ppm sulfur or
less) fuel that meets the ASTM D975 standard or the equivalent for your vehicle. Use
of gasoline or kerosene in diesel engines will result in fuel system and engine damage.
2. Never use diesel fuel with concentrations of methyl ester bio-diesel higher than 5%
(B5), such as B20 or B100.
3. Never add fuel system additives, otherwise, the emission control system could be
damaged.
4. If any type of incorrect fuel is accidentally pumped into the fuel tank, do not turn on
the engine or drive the vehicle, instead, consult an Authorized Mazda Dealer.
5. Turning on the engine or driving the vehicle with the incorrect fuel could cause
damage to the fuel pump and fuel injectors.
6. Do not mistake the refueling port for the DEF filler port. If fuel is added to the DEF
filler port by mistake, do not turn on the engine or drive the vehicle, instead, consult
an Authorized Mazda Dealer.
7. Turning on the engine or driving the vehicle with fuel in the DEF filler port could cause
damage to the emission control system.
NOTE:
1. Fuel for winter driving is available. Ask the gas station attendant for details.
2. When refueling, always add at least 2.6 US gal (10 L, 2.2 Imp gal) of fuel.
Low outside temperatures
When the outside temperature is low, diesel fuel (which is a light oil) may freeze and clog
the fuel pipe, leading to problems such as the engine not starting. When driving to a cold
region, add winter grade diesel fuel as soon as possible.

Starting the Engine
1. The starter motor will not engage until the glow indicator light turns off.
2. If the ignition switch is left ON for a long period of time without the engine running,
the glow plugs could have cooled down. The glow plugs may require warming up
again, which will illuminate the glow indicator light.
3. When starting the engine, do not release the brake pedal until the glow indicator light
in the instrument cluster turns off and the engine starts.
(Technical Background)
1. Heating the glow plugs is controlled by the PCM through the glow control module to
improve engine start ability.
2. Energization time to the glow plugs is determined according to the engine coolant
temperature and engine starting conditions.

The engine speed will increase while the
engine is running an internal cleaning cycle
with the selector lever in the P or N position.
Do not stop the engine while the engine speed
is high. When the cleaning cycle is completed,
the engine speed will return to normal.
(Technical Background)
1. The PCM implements fuel injection control when it determines that the ignition switch
is being switched OFF repeatedly while the engine has not been warmed up sufficiently.
2. To prevent condensation accumulation in the fuel injection system, the combustion
chamber temperature is increased by increasing idle speed to approximately 1,500 rpm
under no-load. When the temperature in the combustion chamber increases to the
specified temperature, the idle speed increase is automatically canceled.

When Driving
▼Diesel Particulate Filter
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:
1. If the vehicle is driven at 9 mph (15 km/h) or less continuously.
2. If the vehicle is repeatedly driven for a short period of time (10 minute or less) or
driven while the engine is cold.
3. If the vehicle is idled for a long time.
When “DPF Clogged” is indicated
When the particulate matter (PM) cannot be removed automatically and the amount of
collected PM has reached a specified amount, perform the following to clear the PM from
the DPF.
1. After the engine has sufficiently warmed up (engine coolant temperature of 176 °F
(80 °C) or more), drive the vehicle at a speed of 12 mph (20 km/h) or more for about
15 to 20 minutes.
CAUTION:
1. 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.
2. If the vehicle is not inspected and continues to be driven, the engine may malfunction.
NOTE:
1. When “DPF malfunction” is indicated in the display, the engine output is restricted to
protect the diesel particulate filter.
2. The engine sound and exhaust gas smell may change when PM is being removed while
driving.
(Technical Background)
1. When the amount of accumulated particulate matter (PM) in the diesel particulate
filter exceeds a certain value, the PCM controls post fuel injection to combust and
eliminate PM.
2. Two methods are available to combust and eliminate PM, one is automatic DPF
regeneration control which is performed by the PCM automatically. The other method
is compulsory DPF regeneration control which can be forcibly performed externally
(using the Mazda Modular Diagnostic System (M-MDS)).
3. During DPF regeneration control, fuel is injected after the main injection to increase the
temperature (follow-up injection, post injection).

4. The value displayed, as the current fuel economy increases, shows a lower MPG value
during DPF regeneration.
▼Selective Catalytic Reduction (SCR) System
The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify
the exhaust gas by injecting it with Diesel Exhaust Fluid (DEF).
WARNING:
Be careful not to allow the DEF to run out. If the DEF completely runs out, the SCR
system will not operate normally. When the remaining DEF is low, a message is displayed
on the multi-information display, and the SCR warning light turns on/flashes. If DEF needs
to be replenished, add DEF following the specified procedure.
NOTE:
1. DEF needs to be replenished periodically according to the scheduled maintenance
information.
2. Normally, the vehicle can be driven about 7,500 miles (12,000 km) before the DEF
needs to be replenished. However, it may need to be replenished earlier depending on
the driving and environmental conditions (i.e. high load on the engine while driving or
driving the vehicle at high altitude).
3. The sound of the SCR system operating may be heard from under the vehicle,
however, this does not indicate a problem.
▼Selective Catalytic Reduction (SCR) System Indications
As the remaining amount of Diesel Exhaust Fluid (DEF) lowers, the SCR system notifies the
driver using the following indications. The vehicle speed may be restricted for a while,
even if the warning light turns off after replenishing the DEF. To cancel the vehicle speed
restriction immediately, switch the ignition OFF after the warning light turns off, then
switch the ignition ON again.

Maintenance
▼Diesel Exhaust Fluid (DEF) Handling
CAUTION:
1. Store DEF in a place out of the reach of children. If DEF gets in your mouth, wash your
mouth with a large amount of water immediately and seek medical attention. If DEF is
mistakenly swallowed, drink 1 to 2 cups of water immediately and seek medical
attention. If DEF gets in your eyes, rinse them with running water immediately and
seek medical attention.
2. Do not use DEF when 2 years have elapsed from the production date indicated on the
container or the use period has expired. If DEF with an expired use period is used, the
Selective Catalytic Reduction (SCR) System may not operate normally.
3. Do not store DEF in the vehicle. DEF may deteriorate or the interior may be damaged
due to fluid leakage from the container.
4. If DEF gets on the painted surface or the interior, wash it off with water or wipe it off
with a wet cloth immediately, otherwise, it may damage the painted surface or the
interior.
5. Do not put DEF into a different container. There may be foreign matter in the
container. If DEF containing foreign matter is used, it could cause a problem with the
SCR system. In addition, changing containers is dangerous because it increases the risk
of accidental ingestion.
NOTE:
1. Store DEF in a cool, dark place. DEF freezes at 12 °F (–11 °C), however, when the
temperature increases, the DEF returns to its original condition.
2. DEF is a colorless, transparent, odorless, and nonpoisonous solution (urea: 32.5 %,
aqueous solution (AUS32)). When opening the container, there may be a smell of
ammonia. Open the container in a well-ventilated area.
3. If DEF gets on your hands, wash them with running water immediately.
▼Diesel Exhaust Fluid (DEF) Replenishment
CAUTION:
1. Use a Mazda genuine product or a product conforming to ISO22241-1 for DEF. If
incompatible DEF is used, the Selective Catalytic Reduction (SCR) system may not
operate normally.
2. Do not dilute DEF with water. If diluted DEF is used, it could cause a problem with the
SCR system or damage it. Do not add any fluid other than DEF to the urea tank. If any
fluid other than DEF is added, it could cause a problem with the SCR system or damage
it. Do not switch the ignition ON, and contact an Authorized Mazda Dealer.

3. When adding DEF, use a bottle with an anti-spill nozzle. If a bottle without an anti-spill
nozzle or a commercial dispenser at a gasoline station is used, it could cause leakage
or the DEF could spray out.
4. Do not overfill the DEF. If the DEF is overfilled, it may freeze during cold temperatures
of 12 °F (–11°C) or less. When urea freezes, it expands and could cause tank breakage.
Always use a bottle with an auto-stop function and stop adding fluid when the autostop function operates.
NOTE:
1. When adding DEF during low temperatures of 12 °F (–11°C) or less, move the vehicle
to a warm location. If the DEF starts to freeze, it may not flow correctly, and the
correct amount may not have been added. In addition, if the fluid freezes in the urea
tank, you may not be able to tell if the correct amount of fluid was added.

▼Recommended Oil
SKYACTIV-D SAE 0W-30 engine oil
Mazda Genuine Oil is used in your Mazda vehicle and is the recommended SKYACTIV-D
SAE 0W-30 lubricant. Mazda Genuine SKYACTIV-D SAE 0W-30 Oil is exclusively for
SKYACTIV-D and required to achieve optimum fuel economy and durability for the Diesel
Particulate Filter. If Mazda Genuine SKYACTIV-D SAE 0W-30 Oil is not available, ACEA C3
0W-30 may be used for oil level maintenance and oil changes however, it is strongly
recommended to replace with Mazda Genuine SKYACTIV-D SAE 0W-30 at the next oil
change to maintain optimum performance.

CAUTION:
SKYACTIV-D 2.2L uses specified oil. Please confirm the specification in owner’s manual. If
engine oil other than the specified oil is used, the Diesel Particulate Filter effective period
of use will be shortened or the Diesel Particulate Filter may be damaged.
NOTE:
Whenever the engine oil is replaced, the vehicles engine control unit needs to be reset as
soon as possible. Otherwise, the engine oil warning light or the wrench indicator light may
display at the wrong time.
(Technical Background)
1. During DPF regeneration, soot or particulate matter (PM) inside the DPF is burnt off
and as a result, ash accumulates inside the DPF. The main sources of soot comes from
engine oil additives. The accumulation of ash in the DPF is an important factor limiting
the service life of the DPF. Since the DPF used in the SKYACTIV-D is light and compact,
its capacity is relatively small. Therefore, in order to retain DPF longevity, the use of
low ash oil is very important.
2. The DPF capacity is diminished when using oils other than Mazda Genuine SKYACTIV-D
SAE as they contain too much ash.
3. Use of non-specified oils also results in premature oil dilution due to the frequent DPF
regeneration attempts to remove the ash.
▼Inspecting Engine Oil Level
When inspecting the engine oil level, pull out the dipstick straight without twisting. In
addition, when inserting the dipstick, always insert it without twisting so that the “X” mark
faces the front of the vehicle.

1. Be sure the vehicle is on a level surface.
2. Warm up the engine to normal operating temperature.
3. Turn it off and wait at least 5 minutes for the oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and reinsert it fully.
5. Pull it out again and examine the level. The level is normal if it is between the MIN and
MAX marks. If it is near or below MIN, add enough oil to bring the level to MAX.
CAUTION:
Do not overfill the engine oil. This may cause engine damage.
6. Make sure the O-ring on the dipstick is positioned properly before reinserting the
dipstick.
7. Reinsert the dipstick fully.
NOTE:
1. Inspect the engine oil level periodically. When inspecting the engine oil, if the engine
oil level exceeds the “X” mark on the dipstick, replace the engine oil. This should be
done by an Authorized Mazda Dealer.
2. When replacing the engine oil, inspect the oil level using the dipstick and refill so that
the engine oil level is within the MIN and MAX range, as shown below.
(Technical Background)

Diesel Particulate Filter (DPF) Regeneration
In order to prevent generating white smoke from the exhaust system after delivery,
burn off protective coating by
performing a DPF Regeneration as instructed in the PDI CX-5 VEHICLE RECEIVING
PROCESS form.
Pressing and holding the “TCS OFF” switch starts a compulsory DPF Regeneration only
when no DPF
Regeneration history has been logged into the PCM.
WARNING:
1. High temperature exhaust gas is emitted during DPF regeneration. People near the
vehicle could be seriously burned, or flammable objects could catch fire. Always
perform compulsory DPF regeneration away from people and flammable objects.
2. If large amounts of exhaust gas are inhaled, it may cause carbon monoxide
poisoning. Always perform compulsory DPF regeneration in a well-ventilated place
(avoid using an exhaust air duct indoors and perform compulsory DPF regeneration
in the open air).
CAUTION:
1. Perform compulsory DPF regeneration with the hood opened to prevent engine

2. If an electrical load is applied, the post injection amount of the fuel injection control
changes and compulsory DPF regeneration cannot be performed normally. Do not
apply an electrical load such as turning on the headlights or the rear window
defroster during compulsory DPF regeneration (A/C cut control is performed during
compulsory DPF regeneration, and A/C is stopped).
3. If there are obstructions such as a wall around the tailpipe, it will obstruct the
exhaust gas passage (airflow), and compulsory DPF regeneration may not be
performed correctly due to the increase in exhaust gas temperature. Always
perform compulsory DPF regeneration with no obstructions around the tailpipe.
4. The temperature in the rear cargo area increases because high temperature exhaust
gas is emitted during DPF regeneration. If an object which can be easily damaged by
heat is in the rear cargo area, such as an electronic device, it could be damaged by
the temperature increase. If compulsory DPF regeneration is performed, do not
place objects such as electronic devices which can be easily damaged by heat in the
rear cargo area.
5. If any DTC other than P2458:00, P2463:00, and P242F:00 is stored, the PCM may
inhibit compulsory DPF regeneration. Before performing compulsory DPF
regeneration, resolve the malfunction and clear the DTC.
