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.

A protective coating is provided over the
aluminum wheels. Special care is needed
to protect t
his coating.
CAUTION
Do not use any detergent other than mild
detergent. Before using any detergent,
verify the ingredients. Otherwise, the
product could discolor or stain the

cleaner, polishing compound, or solvent
on aluminum wheels. They may damage
the coating.

▼ Plastic Part Maintenance
When cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents
or fluids using a
soft cloth immediately.
High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint.
Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage.
In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result in
