Introduction
▼Introduction
Be careful not to hurt yourself when
inspecting your vehicle
, replacing a tire, or
doing some kind of maintenance such as
car washing. In partic ular, wear thick work
gloves such as cotton gloves when
touching areas that are difficult to see
while inspecting or working on your
vehicle. Doing inspections or procedures
with your bare hands 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, preferably an
Authorized Mazda Dealer.

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

For expert advice and quality service,
consult an Authorized Mazda 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 must keep your maintenance
records, receipts, repair orders and any
other documents a s evidence this
maintenance was performed. You must
present these documents, should any
warranty coverage disagreement occur.
Failure to do so ca n result in your
warranty being voided either in whole or
in part.

This evidence may consist of the
following:
The Mazda Scheduled Maintenance
Record, refer to the Warranty Booklet,
must be completely filled out showing
mileage, repair order number, date for
each service, and signed by a qualified
automotive service technician who
service vehicles.
Original copies of rep air 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 maintenance
yourself, displaying mileage and the
date the work was performed. Also,
receipts for the repla cement parts (fluid,
filters, etc.) indi cating 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
workmanship, will not be honored.

Any auto repair shop using parts
equivalent to your Mazda's original
equipment may perform maintenance. But
we recommend that it always be done
by an Authorized M azda Dealer using
genuine Mazda parts.
Selecting “Vehicle Status Monitor”
enables the system t o notify you of your
vehicle's approaching inspection/servicing
period. Refer to the In formation section in
the Mazda Connect Owner's Manual.

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 malfunction diagnosis
devices for servicing. If any device other
than the malfunction diagnosis device is
connected, it may affect the vehicle's
electrical devices or lead to damage such
as battery depletion.
