brakes MAZDA CX3 2023 Owner's Manual

When entering and exiting
interchanges, service areas, and
parking areas of highways (If you exit
a highway 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 ice or
snow-bound 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.)
 Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly, your vehicle may slide
while stopped by the stop hold
control, and it may accelerate
suddenly after it starts moving.)
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
For safety purposes, switch the MRCC
with Stop & Go function system off
when it is not being used.
Leaving the MRCC with Stop & Go
function system turned on when it is
not in use is dangerous as it could
operate unexpectedly, resulting in an
accident.
Do not get out of the vehicle while
the stop hold control is operating: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 MRCC with Stop & Go
function system off, shift the selector
lever to the P position, and apply the
parking brake.
CAUTION
 If your vehicle is towed or you are
towing something, switch the MRCC
with Stop & Go function system off
to prevent an unexpected operation.
 Turn the system
off when the vehicle
is running on a chassis roller.
NOTE
The MRCC with Stop & Go function
system does not detect the following
as physical objects.
Vehicles approaching in the
opposite direction
Pe de st r ia ns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 off the ground in front of
the vehicle, the system may operate.
Therefore, do not use the MRCC

During headway control travel, the
system accelerates and decelerates
your vehicle in conjunction with the
speed of the vehicle ahead.
However, if it is necessary to
accelerate for a lane change or if 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 MRCC with Stop & Go
function system is in use, it does not
cancel even if the selector lever is
operated and any intended engine
braking does not occur. If
deceleration is required, lower the
set speed or depress the brake
pedal.
While braking by the MRCC with
Stop & Go function 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 MRCC with Stop &
Go function 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.
Stop the headway control function to
switch the system to the cruise
control function.

Traffic Jam Assist (TJA)*
▼Tra ffi c
Jam Assist (TJA)
The TJA is a system which consists of a
headway control function and a
steering assist function for reducing
driver fatigue during traffic jams when
driving on expressways or highways.
This system performs headway control
to maintain a constant distance
between your vehicle and a vehicle
ahead at a preset vehicle speed
without you having to use the
accelerator or brake pedal. Even
further, with the steering assist
function, when vehicle lane lines are
detected, the function assists the driver
in keeping the vehicle within the lane
lines. If lane lines are not detected, the
function provides the driver driving
assistance in keeping the vehicle along
the motion path with the vehicle
ahead.
WARNING
Do not rely completely on TJA:

The TJA is not an automated driving
system. In addition, the functions
have limitations. Do not rely
completely on the system and always
stay on course using the steering
wheel.
 Set a vehicle speed within the speed
limit according to the road
conditions and the weather
conditions.
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
sufficiently if a vehicle ahead applies
the brakes suddenly, another vehicle
cuts into the driving lane, or the difference 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
TJA off 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 traffic is heavy with
insufficient 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

 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 different specified size are
used, such as a temporary spare tire.
 Tires with
insufficient tread are used.
 The tire pressures are not adjusted to
the specified 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.
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 off, 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 off when the vehicle
is running on a chassis roller.
 Do not modify the vehicle's
suspensions.
 Always use wheels of the specified
size for the front and rear wheels.

Smart Brake Support(SBS)
*
▼Smart Brake Support (SBS)
The SBS is a system designed to detect
target objects using sensors and
cameras equipped on the vehicle, and
to reduce damage in the event of a
collision by operating the brake control
if there is the possibi
lity of your vehicle
colliding with a target object.
One part of the SBS functions when
you are driving forward and the other
part functions when you are driving in
reverse.
Refer to Forward drive detection on
page 4-156.
Refer to Reverse drive detection on
page 4-158.
▼ Forward drive detection
When you are driving forward, the
following functions of the Smart Brake
Support (SBS) operate.
Forward detection function
WARNING
Do not rely completely on the
SBS:
The SBS is only designed to reduce
damage in the event of a collision.
The system may not operate normally
depending on the target object,
weather conditions, or traffic
conditions. Over reliance on the
system leading to the accelerator pedal
or brake pedal being mistakenly
operated could result in an accident.
CAUTION
In the following cases, turn the SBS off
to prevent a mis-operation.
 The vehicle is being towed or towing
another vehicle.
 The vehicle is driven on rough roads
such as in areas where there is grass
and foliage or off-road.
Refer to Stopping the Smart Brake
Support (SBS) System Operation on
page 4-163.
Forward detection function
The forward detection function is
designed to reduce damage in the
event of a collision with target objects
at the front.
The forward detection function detects
target objects (vehicles ahead,
pedestrians, and bicycles) using the
front radar sensor and the Forward
Sensing Camera (FSC). If there is a
possibility of your vehicle colliding with
a target object at the front, you are
notified of possible danger by a
warning sound and a warning
indication on the display.
Furthermore, if the possibility of a
collision increases, the brake control is
performed to reduce damage in the
event of a collision. In addition, when
the driver depresses the brake pedal,
the brakes are applied firmly and
quickly to assist.

(Vehicles with Driver Monitoring
(DM))
If the system determines that the driver
is not paying attention to the road, it
activates the collision warning earlier
than normal.
Operation conditions
The forward detection function
operates when all of the following
conditions are met.
The ignition is switched ON.The SBS is on.(Object is vehicle ahead)
