2021 MAZDA MODEL 6 maintenance

Selective Catalytic Reduction (SCR) System(SKYACTIV-D 2.2)
The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify
the exhaust gas by injecting it w ith 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.
Refer to Selective Catalytic Reduction (SCR) System Indications on page 4-237.
In this case, consult an Authorized Mazda De aler. If DEF needs to be replenished, add DEF
following the specified procedure.
Refer to Diesel Exhaust Fluid (DEF) Replenishment on page 6-30.
NOTE
DEF needs to be replenished periodically according to the scheduled maintenance
information.
Normally, the vehicle can be driven about 12,000 km (7,500 miles) before the DEF needs
to be replenished. However, it may need to be replenished earlier depending on the
driving and environmental conditions (such as putting a high load on the engine while
driving or driving the vehicle at high altitudes).
The sound of the SCR system operating may be heard from the area 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, t he SCR system notifies
the driver using the fo llowing indications.
The vehicle speed may be restric ted for a while even if the warning light turns off after
replenishing the DEF. To cancel the vehicle speed restriction i mmediately, switch the
ignition OFF after the warning li ght turns off and then switch the ignition ON again.

Operating Tips
Operate the climate control system with
the engine running.
To prevent the battery from being
discharged, do not leave the fan control
switch on for a long period of time with
the ignition switched ON when the
engine is not running.
Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
Use the climate control system to defog
the windows and dehumidify the air.
The recirculate mode should be used
when driving through tunnels or while
in a traffic jam, or when you would like
to shut off outside air for quick cooling
of the interior.
Use the outside air position for
ventilation or windshield defrosting.
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the climate control system.
Run the air cond itioner about 10
minutes at least once a month to keep
internal parts lubricated.
Have the air conditioner checked before
the weather gets hot . Lack of refrigerant
may make the air conditioner less
efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. If the
wrong type of refrigerant is used, it
could result in a ser ious malfunction of
the air conditioner. Consult a
professional, government certified
repairer for the inspection or repair
because a special device is required for
the air conditi oner maintenance.
For details, consult an Authorized
Mazda Dealer.

Introduction
Be careful not to hurt yourself when inspecting your vehicle, replacing a tire, or doing some
kind of maintenance such as car w ashing. In particular, wear thick work gloves such as
cotton gloves when touching areas that are difficult to see whi le inspecting or working on
your vehicle. Doing inspections or procedures with your bare ha nds could cause injury.

If you are unsure about any procedure this manual describes, we strongly urge you to have a
reliable and qualified service shop perform the work, preferabl y an Authorized Mazda
Dealer.

Factory-trained Mazda technicians and genuine Mazda parts are b est for your vehicle.
Without this expertise and the parts that have been designed an d made especially for your
Mazda, inadequate, incomplete, and insufficient servicing may r esult in problems. This
could lead to vehicle damage or an accident and injuries.

For expert advice and quality service, consult an Authorized Ma zda Dealer.

To continue warranty eligibility and to protect your investment , it is your responsibility to
properly maintain your vehicle according to factory recommended schedules outlined in this
manual. As part of this you mu st keep your maintenance records, receipts, repair orders and
any other documents as evidence this maintenance was performed. You must present these
documents, should any warranty coverage disagreement occur. Fai lure to do so can result in
your warranty being voided ei ther in whole or in part.

This evidence may consist of the following:
The Mazda Scheduled Maintenance Record, refer to the Warranty B ooklet, must be
completely filled out showing mileage, repair order number, dat e for each service, and
signed by a qualified automotive service technician who service vehicles.
Original copies of repair orders or other receipts that include the mileage and date the
vehicle was serviced. Each receipt should be signed by a qualified automotive service
technician.
For self maintenance, a statement that you completed the mainte nance yourself,
displaying mileage and the date t he work was performed. Also, receipts for the
replacement parts (fluid, filters , etc.) indicating the date and mileage must accompany this
statement.

NOTE
If you elect to perform maintenance yourself or have your vehicle serviced at a location
other than an Authorized Mazda Dealer, Mazda requires that all fluids, parts and materials
must meet Mazda standards for durability and performance as described in this manual.

Claims against the warranty resulting from lack of maintenance, as opposed to defective
materials or authorized Mazda wo rkmanship, will not be honored.

Any auto repair shop using parts equivalent to your Mazda's ori ginal equipment may
perform maintenance. But we recommend that it always be done by an Authorized
Mazda Dealer using ge nuine Mazda parts.
Selecting “Maintenance Monitor” enables the system to notify yo u of your vehicle's
approaching inspection/servicing period, refer to the Informati on section in the Mazda
Connect Owner's Manual for the details.

The malfunction diagnosis connector is designed exclusively for connecting the specially
designed device to perform on-board diagnosis.
Do not connect any devices other than the specially designed ma lfunction diagnosis devices
for servicing. If any device othe r than the malfunction diagnosis device is connected, it may
affect the vehicle's electrical devices or lead to damage such as battery depletion.
