maintenance MAZDA MODEL 3 HATCHBACK 2018 (in English) User Guide

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 particular, wear thick work gloves such as cotton gloves when touching areas that are
difficult to see while inspecting or working on your vehicle. D oing inspections or
procedures with your bare hands could cause injury.

If you are unsure about any procedure it 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 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 (page 6-16).

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.
