2023 MAZDA CX30 service

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 Mazda 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
Information 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.

Wiper Blades
▼Wiper Blades
CAUTION

Hot waxes applied by automatic car
washers have been known to
affect
the wiper's ability to clean windows.
 An operation malfunction may occur
or the wiper
effectiveness may be
reduced if a water-repellent coating
is used.
 To prevent damage to the wiper
blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.
 When the wiper lever is in the AUTO
position and the ignition is switched
ON, the wipers may move
automatically in the following cases:
 If the windshield above the rain
sensor is touched.
 If the windshield above the rain
sensor is wiped with a cloth.
 If the windshield is struck with a
hand or other object.
 If the rain sensor is struck with a
hand or other object from inside
the vehicle.
Be careful not to pinch hands or fingers as it may cause injury, or
damage the wipers. When washing
or servicing the vehicle, make sure
the wiper lever is in the OFF
position.
 Before lifting the windshield wiper
blades
off the windshield, always
follow the procedur e for moving the
windshield wiper blades. Otherwise,
a wiper blade, wiper arm, or the
hood could be damaged.
Refer to the Replacing Windshield
Wiper Blades (page 6-22) section
for the procedure on how to move
the windshield wipe r blades to the
service position.
Contamination of either the
windshield or the b lades with foreign
matter can reduce wiper effectiveness.
Common sources are insects, tree sap,
and hot wax treatments used by some
commercial car washes.
If the blades are not wiping properly,
clean the window and blades with a
good cleaner or mild detergent; then
rinse thoroughly with clean water.
Repeat if necessary.
▼ Replacing Windshield Wiper
Blades
When the wipers no longer clean well,
the blades are probably worn or
cracked.
Replace them.
CAUTION

To prevent damaging a windshield
wiper blade, wiper arm, or the hood,
perform the following procedure.
 Before lifting the windshield wiper
blades off the windshield, always
move them to the service position.
 When putting the windshield
wiper blades back on the
windshield, make sure that they
are in the service position before
switching the ignition ON and
operating the windshield wipers.
 Replace with Mazda genuine wiper
blades. If they are replaced with
wiper blades other than a Mazda
genuine product, they may not wipe
with the same efficiency as the
genuine product.
