maintenance MAZDA MODEL 3 HATCHBACK 2020 (in English) Repair Manual

▼Active Driving Display
Maintenance*
The dust-proof sheet has a coating. When
cleaning, do not use a hard or
rough-surface cloth, or cleaning detergent.
In addition, if a chemical solvent gets on
the active driving display, wipe it off
immediately. The dust-proof sheet could
be damaged and the surface coating could
be scratched. Use a fine, soft cloth such as
those used for cleaning eyeglasses.
NOTE
Use of compressed air when cleaning the
dust-proof sheet is recommended.
▼Panel Maintenance
If a panel becomes soiled, wipe it off with
a soft cloth soaked in clean water and
thoroughly wrung out.
If some areas require further cleaning, use
the following procedure:
1. Wipe the soiled area with a soft cloth
soaked in a mild detergent (approx.
5 %) diluted with water.
2. Wipe off the remaining detergent using a cloth soaked in clean water and
wrung out well.
NOTE
Be particularly careful when cleaning
shiny surface panels and metallic parts
such as plating as they can be scratched
easily.
▼Cleaning the Window Interiors
If the windows become covered with an
oily, greasy, or waxy film, clean them with
glass cleaner. Follow
the directions on the
container.
CAUTION
 Do not scrape or scratch the inside of the
window glass. It could damage the
thermal filaments and the antenna lines.
 When washing the inside of the window
glass, use a soft cloth dampened in
lukewarm water, gently wiping the
thermal filaments and the antenna lines.
Use of glass cleaning products could
damage the thermal filaments and the
antenna lines.
▼ Cleaning the Floor Mats
Rubber floor mats should be cleaned with
mild soap and water only.
WA R N I N G
Do not use rubber cleaners, such as tire
cleaner or tire shine, when cleaning rubber
floor mats:
Cleaning the rubber floor mats with rubber
cleaning products makes the
floor mats
slippery.
This may cause an accident when
depressing the accelerator, brake, or clutch
(Manual transmission) pedal or when
getting in or out of the vehicle.
After removing the floor mats for
cleaning, always reinstall them securely
(page 3-46).

5–Door
Perform the removal procedure in reverse.
Maintenance
Always keep the jack clean.
Make sure the moving parts are kept
free from dirt or rust.
Make sure the screw thread is
adequately lubricated.
▼Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WA R N I N G
Do not install the temporary spare tire on
the front wheels (driving wheels):
Driving with the temporary spare tire on
one of the front driving wheels is
dangerous. Handling will be
affected. You
could lose control of the vehicle, especially
on ice or snow bound roads, and have an
accident. Move a regular tire to the front
wheel and install the temporary spare tire
to the rear.
CAUTION
 When using the temporary spare tire,
driving stability may decrease compared
to when using only the conventional tire.
Drive carefully.
To avoid damage to the temporary spare
tire or to the vehicle, observe the
following precautions:
 Do not exceed 80 km/h (50 mph).
 Avoid driving over obstacles. Also, do
not drive through an automatic car
wash. This tire's diameter is smaller
than a conventional tire, so the ground
clearance is reduced.
 Do not use a tire chain on this tire
because it will not
fit properly.
 Do not use your temporary spare tire
on any other vehicle, it has been
designed only for your Mazda.
 Use only one temporary spare tire on
your vehicle at the same time.
To remove the spare tire
4–Door
1. Remove the trunk mat.

“Key Not Detected” is displayed
If the presence of the key cannot be
detected (dead battery, battery
malfunction, no key), it is displayed
when the driver attempts to start the
engine (push button start operation,
brake pedal depression).
Displayed when it is determined that a
key that was in the vehicle has been
removed from the vehicle. (Key taken
out warning. Other than IG-OFF)
▼ High Beam Control System (HBC)
Warning Indication/Warning Light
(Amber)
*
The light remains turned on if there is a
problem with the system. Have your
vehicle inspected at an Authorized Mazda
Dealer.
▼i-ACTIVSENSE Warning
Indication/Warning Light*
The indication displays
if the system has a
malfunction.
Check the reason for the indication
displaying on the center display or
multi-information display.
Refer to If a Warnin g Light Turns On or
Flashes on page 7-27.
▼ Exterior Light Warning Indication/
Wa r n i n g L i g h t
This light illuminates if there is a
malfunction in the exterior lights (except
license plate lights). Have your vehicle
inspected by an Authorized Mazda Dealer.
CAUTION
Do not drive the vehicle while an exterior
light has a malfunction. Poor visibility, and
not being able to signal braking and turns
may cause an accident. In addition, if the
vehicle is driven with the lights not turned
on, it may
conflict with laws and
regulations due to poor maintenance.
▼ Low Fuel Warning Indication/
Wa r n i n g L i g h t
The light turns on when the remaining fuel
is about 9.0 L (2.3 US gal, 1.9 Imp gal). If
you continue to drive after the light turns
on without refueling and the fuel gauge
reaches nearly empty
, the light flashes.
NOTE
The light illumination timing may vary
because fuel inside the fuel tank moves
around according to the driving conditions
and the vehicle posture.

Tire Maintenance
▼Tire Maintenance
Improper or inad
equate vehicle
maintenance can cause tires to wear
abnormally. Here are some important
maintenance points:
▼ Tire Inflation Pressure
Inspect all tire p
ressure monthly
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, top handling, and minimum
tire wear. Use the pressures specified on
the vehicle tire inform ation placard or tire
label for optimum service.
▼ Tire Rotation
To equalize tread wear, rotate the tires
every 16,000 km (10,000 miles) at the
latest or sooner if irregular wear develops.
Mazda recommends to rotate every 8,000
km (5,000 miles) to help increase tire life
and distribute wear more evenly.
1. Forward
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.

Inspect the tires for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel
Severe braking
After rotation, inflate all tire pressures to
specification (page 9-9) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial tires
that have an asymmetrical tread pattern or
studs only from front to rear, not from side
to side. Tire performance will be weakened
if rotated from side to side.
▼ Replacing a Tire
WA R N I N G
Always use tires that are in good condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and traction
could result in an accident.
If a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.
1. New tread
2. Worn tread
3. Tread wear indicator

You should replace the tire before the band
crosses the entire tread.
