image and the seams where each of
the camera images merge are blind
spots where an obstruction may not be
visible. In addition, the extended
vehicle width lines and projected
vehicle path lines are only to be used

Introduction
▼Introduction
Be careful not to hurt yourself when
inspecting your vehicle, replacing a
tire, or doing some kind of
maintenance such as changing the oil
and
filter. 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. 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, and
insu fficient 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 as evidence this
maintenance was performed. You must
present these documents, should any
warranty coverage disagreement occur.
Failure to do so can 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 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 maintenance
yourself, displaying mileage and the
date the work was performed. Also,
receipts for the replacement parts ( fl uid, filters, etc.) indicating the date
and mileage must accompany this
statement.
