2021 MAZDA MODEL 3 HATCHBACK warning

▼When a tire pressure decreases
If the TPMS warning light turns on, a
tire pressure may be low. Inspect the
tire pressures and adjust them to the
correct in
flation pressure.
Refer to Tire Pressure Monitoring
System (TPMS) Warning Indication/
Warning Light (Turns on) on page
7-37.
▼ Tires and Wheels
CAUTION
When inspecting/adjusting the tire
pressures, do not apply excessive force
to the air valve of the tire pressure
sensor. Otherwise, the tire pressure
sensor could be damaged.
When changing tires and wheels
When changing the tires or wheels
(such as installing winter tires), it will
be necessary to regi
ster the ID signal
code of the tire pressure sensor to the
TPMS.
Have an Authorized Mazda Dealer do
the registration or register the ID signal
codes of the tire pressure sensors using
the following procedure.
NOTE
The tire pressure sensors on each
wheel have a unique ID signal code.
For the TPMS to operate correctly, the
ID signal codes of the tire pressure
sensors need to be registered to the
system.
1. Wait more than 19 minutes after changing a tire or wheel.
2. After more than 19 minutes havepassed, drive the vehicle at a speed
of about 25 km/h (16 mph) or
faster for 3 minutes or longer. While
driving, the ID signal codes of the
tire pressure sensors are
automatically registered.
NOTE
If you drive the vehicle within 19
minutes of changing a tire or wheel,
the TPMS warning light will fl ash
because the ID signal codes for the tire
pressure sensors were not registered.
In this case, stop the vehicle and
register the ID signal codes of the tire
pressure sensors following the
procedure.
When replacing tires and wheels
CAUTION
 When replacing the tires and wheels,
consult an Authorized Mazda Dealer
Otherwise, the tire pressure sensors
could be damaged when replacing
them.
 Do not install non-genuine wheels. If
wheels other than genuine ones are
installed, it may not be possible to
install the tire pressure sensors.
When replacing a tire or wheel, always
install the tire pressure sensor. The
following combinations of tires,
wheels, or tires and wheels are
possible.
The tire pressure sensor from the old
wheel is removed and it is installed
to the new wheel.
Only a tire is replaced without
replacing the tire pressure sensor and
wheel.
A new tire pressure sensor is installed
to a new wheel.

Rear View Monitor*
▼Rear View Monitor
The rear view monitor provides visual
images of the rear of the vehicle when
reversing.
WARNING
Always drive carefully con
firming the
safety of the rear and the surrounding
conditions by looking directly with
your eyes:
Reversing the vehicle by only looking at
the screen is dangerous as it may cause
an accident or a collision with an
object. The rear view monitor is only a
visual assist device when reversing the
vehicle. The images on the screen may
be different from the actual conditions.
CAUTION

Do not use the rear view monitor
under the following conditions:
Using the rear view monitor under
the following conditions is
dangerous and could result in injury
or vehicle damage or both.
 Icy or snow-covered roads.
 Tire chains or a temporary spare
tire is installed.
 The vehicle is on a road incline.
 When the display is cold, images
may course across the monitor or the
screen and may be dimmer than
usual, which could cause di fficulty in
con firming the surrounding
conditions of the vehicle. Always
drive carefully confirming the safety
of the rear and the surrounding
conditions by looking directly with
your eyes.
 Do not apply excessive force to the
camera. The camera position and
angle may deviate.
 Do not disassemble, modify, or
remove it as it may no longer be
waterproof.
 The camera cover is made of plastic.
Do not apply degreasing agents,
organic solvents, wax, or glass
coating agents to the camera cover.
If any are spilled on the cover, wipe
o ff with a soft cloth immediately.
 Do not rub the camera cover
forcefully with an abrasive or hard
brush. The camera cover or lens may
be scratched which might aff ect the
images.
NOTE
If water, snow, or mud is stuck on
the camera lens, wipe it off using a
soft cloth. If it cannot be wiped o ff,
use a mild detergent.
If the camera temperature changes
rapidly (Hot to cold, cold to hot), the
rear view monitor may not operate
correctly.
When replacing the tires, consult an
Authorized Mazda Dealer. Replacing
the tires could result in deviation of
the guide lines which appear on the
display.
If the vehicle's front, side, or rear has
been involved in a collision, the
alignment of the rear view parking
camera (location, installation angle)
may have deviated. Always consult
an Authorized Mazda Dealer to have
the vehicle inspected.
If “No camera signal.” is indicated in
the display, there could be a
problem with the camera. Have your
vehicle inspected at an Authorized

Parking Sensor System*
▼Pa r k i n g S e n s o r Sys t e m
The parking sensors use ultrasonic sensor
s which detect obstructions around the
vehicle when the vehicle is driven at low speeds, such as during garage or parallel
parking , and a buzzer sound and detection indicator notify the driver of the
approximate distance from the vehicle to the surrounding obstruction.

1. Front ultrasonic sensor*
2. Front corner ultrasonic sensor*
3. Rear ultrasonic sensor
4. Rear corner ultrasonic sensor
5. Rear side ultrasonic sensor
*
WARNING
Do not rely completely on the parking sensor system and be sure to con firm the
safety around your vehicl e visually when driving:
This system can assist the driver in operating the vehicle in the forward and
backward directions while parking. The detection ranges of the sensors are limited,
therefore, driving the vehicle while relying only on the system may cause an
accident. Always con firm the safety around your vehicle visually when driving.
