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 to 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.
