instrument cluster MAZDA MODEL 3 HATCHBACK 2021 Workshop Manual

WARNING
Do not rely completely on the DM
and always drive carefully:
The DM is a system which detects
driver fatigue and sleepiness, and
encourages the driver to take a rest.
This is not designed to prevent driver
fatigue and sleepiness, and
over-reliance on the system could lead
to an accident. Drive carefully and turn
the steering wheel appropriately.
In addition, the system may not be
able to detect driver fatigue and
sleepiness correctly depending on the
traffic and driving conditions. The
driver must take sufficient rest in order
to drive safely.
Operation conditions
The DM begins monitoring after 20
minutes have passed since the driver
began driving the vehicle and when
the vehicle speed is about 5 km/h (3
mph) or faster.
NOTE
If the vehicle speed decreases to less
than about 5 km/h (3 mph) while
the DM is monitoring, the DM stops
monitoring for 6 minutes even if the
vehicle speed returns to about 5
km/h (3 mph) or faster.
If the driver monitoring camera does
not recognize the driver correctly, the
DM may not monitor correctly.
Refer to Driver Monitoring Camera
on page 4-214.
After the DM has displayed the first
message encouraging the driver to
take a rest, it does not display it
again during the following periods.
After displaying the warning
pattern (caution), the next warning
pattern (caution) is not displayed
until 45 minutes have passed.
After displaying the warning
pattern (warning), the next
warning pattern (warning) is not
displayed until 15 minutes have
passed.
After displaying the warning
pattern (warning), the next
warning pattern (caution) is not
displayed until 45 minutes have
passed.
▼ Driver Monitoring (DM) Display
When the Driver Monitoring (DM)
detects driver fatigue or sleepiness, it
activates the warning sound and
displays an alert in the instrument
cluster.

▼Front Radar Sensor
Your vehicle is equipped with a front
radar sensor.

The front radar sensor functions by
detecting the radio waves re flected o ff
a vehicle ahead or an obstruction sent
from the radar sensor.
The front radar sensor is mounted
behind the front emblem.

Cruise Set Indication (Green)
The indication turns on (green) when a
cruising speed has been set.
▼Activation/Deactivation
WARNING
Always turn o
ff the cruise control
system when it is not in use:
Leaving the cruise control system in an
activation-ready state while the cruise
control is not in use is dangerous as the
cruise control could unexpectedly
activate if the activation button is
accidentally pressed, and result in loss
of vehicle control and an accident.
NOTE
When the ignition is switched OFF, the
system status before it was turned o ff is
maintained. For example, if the
ignition is switched OFF with the cruise
control system operable, the system
will be operable when the ignition is
switched ON the next time.
Activation
To activate the system, press the cruise
switch. The cruise standby indication
(white) turns on.
Deactivation
To deactivate the system, press the
cruise switch again.
The cruise standby indication (white)
turns off .
▼To Set Speed
1. Activate the cruise control system
by pressing the cruise switch. The
cruise standby indication (white)
turns on.
2. Accelerate to the desired speed, which must be more than 25 km/h
(16 mph).
3. Adjust the system to the desired vehicle speed using the accelerator
pedal. Press the RES switch up (SET
+) or down (SET -) to start cruise
control. The cruise control
indication (green) in the instrument
cluster turns on at the same time.
Quickly release the switch when the
cruise control indication (green)
turns on.
NOTE
If the RES switch is operated up (SET
+) or down (SET -) while the vehicle
speed is between 25 and 30 km/h
(16 to 19 mph), the set speed is set
to 30 km/h (19 mph).
The cruise control speed setting
cannot be performed under the
following conditions:
Any of the doors is opened.The driver's seat belt is unfastened.The brake pedal is depressed.The parking brake is applied.(Automatic transmission)
The selector lever is in the P, N, or
R position.
(Manual transmission)
The shift lever is in the neutral
position.
On a steep grade, the vehicle may
momentarily slow down while
ascending or speed up while
descending.

The cruise control will cancel if the
vehicle speed decreases below 20
km/h (12 mph) when the cruise
control is activated, such as when
climbing a steep grade.
The vehicle speed preset using the
cruise control is displayed in the
instrument cluster and the active
driving display (vehicles with active
driving display).

▼ Changing the Set Vehicle Speed
Follow either of these procedures.
To increase/decrease speed using
cruise control switch
When the RES switch is pressed up
(SET+), the vehicle accelerates and
when the RES switch is pressed down
(SET
-), it decelerates.
Press and release immediately: 1
km/h (1 mph)
Press and hold: 10 km/h (5 mph)
NOTE
Even after releasing the RES switch, the
cruise control accelerates/decelerates
continuously until the set speed
displayed in the instrument cluster and
on the active driving display is reached.
If you want to stop accelerating/
decelerating , change the set speed or
cancel the system (such as by
depressing the brake pedal).
To increase speed using accelerator
pedal
Depress the accelerator pedal and
press the RES switch up (SET+) or
down (SET
-) at the desired speed. If
the switch is not operated, the system
returns to the set speed after you
release your foot from the accelerator
pedal.
NOTE
Accelerate if you want to speed up
temporarily when the cruise control is
on. Greater speed will not interfere
with or change the set speed. Take
your foot o ff the accelerator to return
to the set speed.

Tire Pressure MonitoringSystem (TPMS)
▼Tire Pressure Monitoring System
(TPMS)
The TPMS monitors the air pressure of
each tire and if it decreases below the
speci
fied value, the system
notifies the
driver by turning on the TPMS warning
light in the instrument cluster and
indicating a message on the
multi-information display.
For the TPMS, the air pressure data
sent from the tire pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tire pressures.
1. Tire pressure sensors

In addition, the current tire pressures
can be checked using the center
display.
Refer to the Vehicle Status Monitor
section in the Mazda Connect
Owner's Manual.
NOTE
When the ambient temperature is
low, the tire temperatures also
decrease. If the tire temperatures
decrease, the air pressure in the tires
will also decrease which could turn
on the TPMS warning light.
Before driving, visually inspect the
tires for abnormalities. Additionally,
inspect the tire pressures monthly. A
digital type air pressure gauge is
recommended for inspecting the tire
pressures.
The TPMS is not a substitute for your
own periodic inspection of the tires.
Always inspect the tires yourself
periodically.
CAUTION
 Each tire, including the spare (if
provided), should be checked
monthly when cold and
inflated to
the in flation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire in flation pressure label, you
should determine the proper tire in flation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure telltale when one or more
of your tires is significantly
under-in flated. Accordingly, when
the low tire pressure telltale
illuminates, you should stop and
check your tires as soon as possible,
and in flate them to the proper
pressure. Driving on a signi ficantly
under-in flated tire causes the tire to
overheat and can lead to tire failure.
Under-in flation also reduces fuel
e ffi ciency and tire tread life, and may
a ff ect the vehicle's handling and
stopping ability.

Parking in an Emergency
▼Parking in an Emergency
The hazard warning lights should
always be used when you stop on or
near a roadway in an emergency.

The hazard warning lights warn other
drivers that your vehicle is a tra
ffic
hazard and that they must take
extreme caution when near it.

Depress the hazard warning flasher
and all the turn signals will flash. The
hazard warning indicator lights in the
instrument cluster flash simultaneously.
NOTE
The turn signals do not work when
the hazard warning lights are on.
Check local regulations about the
use of hazard warning lights while
the vehicle is being towed to verify
that it is not in violation of the law.

For an operation check, make sure that
the light turns on when the ignition is
switched on, and turns o
ff a few
seconds later or when the engine is
started.
When the light turns on
If the brake system warning light
