parking brake MAZDA MODEL 3 HATCHBACK 2021 Owner's Guide

The TJA may not be able to detect a
vehicle ahead depending on the type
of vehicle ahead and its conditions,
the weather conditions, and the road
conditions. Additionally, the system
might be unable to decelerate
su fficiently if a vehicle ahead applies
the brakes suddenly, another vehicle
cuts into the driving lane, or the di fference in vehicle speed between
your vehicle and the vehicle ahead is
larger, which could result in an
accident. Check the surrounding
conditions and always drive carefully
while keeping a safe distance from
vehicles ahead and on-coming
vehicles.

For the purposes of safety, switch the
TJ A o ff when it is not being used.
Leaving the TJA turned on when it is
not in use is dangerous as it could
operate unexpectedly, resulting in an
accident.

Do not use the TJA under the
following conditions. Otherwise, it
may result in an accident.
 General roads other than
expressways or highways (Driving
under these conditions using the TJA
is not possible.)
 Roads with sharp curves and where
vehicle traffi c is heavy with
insuffi cient space between vehicles,
or roads where frequent and
repetitive acceleration and
deceleration occur (Driving under
these conditions using the TJA is not
possible). When entering and exiting
interchanges, service areas, and
parking areas of expressways (If you
exit an expressway while headway
control is in use, the vehicle ahead
will no longer be tracked and your
vehicle may accelerate to the set
speed).
 Slippery roads such as icy or
snow-covered roads (Tires could spin
causing you to lose vehicle control,
or the stop hold control may not
operate.)
 Long, descending slopes (to
maintain distance between vehicles,
the system automatically and
continuously applies the brakes
which could result in the loss of
brake power.)
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
 (Automatic transmission vehicle)
Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly, your vehicle may slip while
stopped by the stop hold control, or
it may accelerate suddenly after it
starts moving.)
 Driving under bad weather
conditions (rain, fog , and snow).
 The vehicle is driven on slippery
roads such as icy or snow -covered
roads and unpaved roads (Tires
could spin causing you to lose
vehicle control, or the stop hold
control may not operate.)
 Tires of a di fferent specified size are
used, such as a temporary spare tire.
 Tires with insu fficient tread are used.
 The tire pressures are not adjusted to
the
speci fied pressure.
 The vehicle is being used to tow a
camper or boat trailer.
 Tire chains are used.

The vehicle is driven on roads with
lane lines other than white (yellow)
lines, such as an expressway.

Do not get out of the vehicle while
the stop hold control is operating.
(Automatic transmission vehicle)
Getting out of the vehicle while the
stop hold control is operating is
dangerous as the vehicle may move
unexpectedly and result in an accident.
Before getting out of the vehicle,
switch the TJA o ff, apply the parking
brake, and then shift the selector lever
to the P position.

CAUTION
Turn the system off when the vehicle is
running on a chassis roller.
Heed the following cautions so that
the TJA can operate normally.
 Turn the system o ff when the vehicle
is running on a chassis roller.
 Do not modify the vehicle's
suspensions.
 Always use wheels of the speci fied
size for the front and rear wheels.
Consult an Authorized Mazda Dealer
for tire replacement.

NOTE
The headway control does not detect
the following as physical objects.
Vehicles approaching in the
opposite direction
Pe d e s t r i a n sStationary objects (stopped
vehicles, obstructions)
If a vehicle ahead is traveling at an
extremely low speed, the system may
not detect it correctly.
If there is a structure on the road or
an object (such as a monorail) at a
low height o ff the ground in front of
the vehicle, the system may operate.
Therefore, do not use the TJA.
Do not use the TJA under conditions
in which close proximity warnings
are frequently activated.
If it is necessary to accelerate for a
lane change or the vehicle ahead
brakes suddenly causing you to close
in on the vehicle rapidly, accelerate
using the accelerator pedal or
decelerate using the brake pedal
depending on the conditions.
While the TJA is in use, any intended
engine braking does not occur even
if you shift the shift lever (manual
transmission) or the selector lever
(automatic transmission). If
deceleration is required, lower the
vehicle speed setting or depress the
brake pedal.
While braking by the TJA control is
operating , you might hear an
operation sound, however, this does
not indicate a problem.
The brake lights turn on while
braking by the TJA control is
operating , however, they may not
turn on while the vehicle is on a
down slope at the set vehicle speed
or traveling at a constant speed and
following a vehicle ahead.
Under the following conditions, the
TJA may not be able to detect white
(yellow) lines or vehicles ahead
correctly and the TJA may not
operate normally.
The forward sensing camera (FSC)
cannot recognize the area in front
of the vehicle due to soiling or fog.

Smart Brake Support
[Rear Crossing] (SBS -RC)
*
▼ Smart Brake Support [Rear
Crossing]
(SBS-RC)
The SBS -RC is a system designed to
assist the driver in avoiding collisions
and to reduce damage in the event of
a collision by applying the brakes if
there is the possibility of collision with
a vehicle approaching from the rear
while you are reversing out of parking
space.
The SBS -RC system detects vehicles
approaching from the rear left and
right sides of the vehicle, and the rear
of the vehicle while the vehicle is being
reversed out of a parking space, the
system reduces damage in the event of
a collision by operating the brake
control when the system determines
that a collision is unavoidable.
SBS -RC operation
1. The
SBS-RC system operates when
the shift lever (manual
transmission) or the selector lever
(automatic transmission) is shifted
to the reverse (R) position.
2. If there is the possibility of a
collision with an approaching
vehicle, the SBS-RC system applies
brake and displays “BRAKE!” on the
active driving display and the
multi-information display.
WARNING
Always check the surrounding area
visually before actually putting the
vehicle in reverse:
The system is only designed to assist
you in backing out of the lot when
putting the vehicle in reverse. Due to
certain limitations with the operation
of this system, the SBS -RC system may
not operate brake or it might be
delayed even though a vehicle is
behind your vehicle. Always make it
your responsibility as a driver to check
the rear.
Do not rely completely on the SBS -RC
system:
 The
SBS-RC system is only designed
to reduce damage in the event of a
collision. Over reliance on the system
leading to the accelerator pedal or
brake pedal being mistakenly
operated could result in an accident.
 The
SBS-RC system operates in
response to a vehicle. The system
does not operate in response to
obstructions such as a wall,
pedestrians, or animals.
