Antilock Brake System(ABS)
▼Antilock Brake System (ABS)
The ABS control unit continuously
monitors the speed of each wheel. If
one wheel is about to lock up, the ABS
responds by automatically releasing
and reapplying that wheel's brake.

The driver will feel a slight vibration in
the brake pedal and may hear a
chattering noise from the brake system.
This is normal ABS system operation.
Continue to depress the brake pedal
without pumping the brakes.

The warning light turns on when the
system has a malfunction.
Refer to ABS Warning Indication/
Warning Light on page 7-26.
WARNING
Do not rely on ABS as a substitute for
safe driving:
The ABS cannot compensate for unsafe
and reckless driving , excessive speed,
tailgating (following another vehicle
too closely), driving on ice and snow,
and hydroplaning (reduced tire friction
and road contact because of water on
the road surface). You can still have an
accident.
NOTE
Braking distances may be longer on
loose surfaces (snow or gravel, for
example) which usually have a hard
foundation. A vehicle with a normal
braking system may require less
distance to stop under these
conditions because the tires will
build up a wedge of surface layer
when the wheels skid.
You might hear the sound of a motor
when starting the EV system or
immediately after starting to drive
the vehicle. However, it does not
indicate a problem.

Mazda Radar Cruise
Control with Stop & Go function (MRCC with
Stop & Go function)
*
▼ Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function)
The MRCC with Stop & Go function is
a system designed to enable
constant-speed driving at a set speed
and headway control to maintain a
constant distance with a vehicle ahead
according to your vehicle speed. The
system automatically accelerates,
decelerates, and stops your vehicle
without you having to depress the
accelerator or brake pedal.

Also refer to the following information
before using the MRCC with Stop &
Go function.
Refer to Forward Sensing Camera
(FSC) on page 4-71.
Refer to Front Radar Sensor on page
4-77.
WARNING
Do not rely completely on the MRCC
with Stop & Go function and always
drive carefully:
The MRCC with Stop & Go function
may not be able to detect a vehicle
ahead depending on the type of
vehicle and its conditions, the weather
conditions, and the road conditions.
Additionally, the system might be
unable to decelerate su
fficiently if the
vehicle ahead applies the brakes
suddenly or another vehicle cuts into
your lane, which could result in an
accident.
Always check the surrounding
conditions and depress the brake
pedal or accelerator pedal while
keeping a safe distance from a vehicle
ahead or a vehicle following behind
you.
Do not use the system under the
following conditions. Otherwise, it
may result in an accident:
 The vehicle is driven on roads other
than highways.
 The vehicle is driven on roads with
sharp curves or with heavy tra ffic
where su fficient distances between
vehicles cannot be kept.
 The vehicle is driven on roads where
acceleration and deceleration are
frequently repeated.
 The vehicle is exiting the main lane
on an expressway to enter an
interchange, a rest area, or a parking
area.
 The vehicle is driven on slippery
roads such as icy roads,
snow-covered roads, and unpaved
roads.
 The vehicle is driven on a long
downslope.
 The vehicle is driven on a steep
slope.
 A two-wheeled vehicle such as a
motorcycle or bicycle is traveling
ahead.
 The vehicle is being towed.
 Proximity warnings activate
frequently.
Switch the MRCC with Stop & Go
function off when it is not being used.
Leaving the MRCC with Stop & Go
function on when it is not in use is
dangerous as it could operate
unexpectedly, resulting in an accident.

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 leaving the vehicle, switch the
MRCC with Stop & Go function off,
shift the selector lever to the P

Traffic Jam Assist (TJA)*
▼ Tra
ffic Jam Assist (TJA)
The TJA is a system designed to reduce
driver fatigue during
traffic jams when
driving on expressways or highways.
The TJA consists of a headway control
function and a steering assist function.

Headway control function
The function performs headway
control to maintain a constant distance
between your vehicle and a vehicle
ahead at a preset vehicle speed
without you having to depress the
accelerator or brake pedal.

Steering assist function
When vehicle lane lines are detected,
the function assists your steering
operation to follow the vehicle lane
lines.
When vehicle lane lines are not
detected, the function assists your
steering operation to follow the
trajectory of the vehicle ahead.

Also refer to the fo llowing information
before using the TJA.
Refer to Forward Sensing Camera
(FSC) on page 4-71.
Refer to Front Radar Sensor on page
4-77.
WARNING
Do not rely completely on the TJA and
always drive carefully:
 The TJA is not an automated driving
system. Therefore, the function has
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
suffi ciently if the vehicle ahead
applies the brakes suddenly or
another vehicle cuts into your lane,
which could result in an accident.
Do not use the system under the
following conditions. Otherwise, it
may result in an accident:
 The vehicle is driven on roads other
than expressways and highways.
 The vehicle is driven on roads with
sharp curves or with heavy tra ffic
where su fficient distances between
vehicles cannot be kept.
 The vehicle is driven on roads where
acceleration and deceleration are
frequently repeated.
 The vehicle is exiting the main lane
on an expressway to enter an
interchange, a rest area, or a parking
area.
 The vehicle is driven on slippery
roads such as icy roads,
snow-covered roads, and unpaved
roads.
 The vehicle is driven on a long
downslope.
 The vehicle is driven on a steep
slope.
 A two-wheeled vehicle such as a

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 4-136.
Refer to Reverse drive detection on
page 4-138.
▼ 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 tra ffic
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 o ff
to prevent a mis-operation.
 The vehicle is being towed.
 The vehicle is driven on rough roads
such as in areas where there is grass
and foliage or o ff-road.
Refer to Stopping the Smart Brake
Support (SBS) System Operation on
page 4-143.
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
noti fied 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 power switch is switched ON.The SBS is on.(Object is vehicle ahead)
