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 original 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 (page 6-15).

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.
