NOTE
If the Electric Parking Brake (EPB)
switch is pulled while the AUTOHOLD
is operating, the parking brake is
applied and the AUTOHOLD is
released. In addition, if the parking
brake is released under this condition,
the AUTOHOLD operates to hold the
brakes.
Under the following conditions, the
parking brake is automatically applied
and the AUTOHOLD is released. The
AUTOHOLD is re-enabled when the
conditions before the AUTOHOLD is
released are restored.
The driver’s seat belt is unfastened.
The driver’s door is opened.
When about 10 minutes or longer have
passed since the AUTOHOLD operation
started, the parking brake is
automatically applied. Because the
AUTOHOLD is restored when releasing
the parking brake, the hold on the
brakes by AUTOHOLD function
resumes.
(Manual transaxle vehicle)
When starting to drive the vehicle
forward or in reverse on a down slope,
depress the clutch pedal and shift the
shift lever to the appropriate position for
driving in the desired direction, and then
depress the accelerator pedal to release
the AUTOHOLD.
▼AUTOHOLD System is Turned Off
Depress the brake pedal and press the
AUTOHOLD switch. The AUTOHOLD is

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 Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-29.
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.
The sound of the ABS operating may be
heard when starting the engine or
immediately after starting the vehicle,
however, it does not indicate a
malfunction.

Traction Control System(TCS)
The Traction Cont rol System (TCS)
enhances traction and safety by controlling
engine torque and braking. When the TCS
detects driving wheel slippage, it lowers
engine torque and operates the brakes to
prevent loss of traction.

This means that on a slick surface, the
engine adjusts automatically to provide
optimum power to the drive wheels,
limiting wheel spin and loss of traction.

The warning light turns on when the
system has a malfunction.
Refer to Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-29.
WA R N I N G
Do not rely on the Traction Control System
(TCS) as a substitute for safe driving:
The Traction Control System (TCS) cannot
compensate for unsafe and reckless
driving, excessive speed, tailgating
(following another vehicle too closely), and
hydroplaning (reduced tire friction and
road contact because of water on the road
surface). You can still have an accident.
Use snow tires or tire chains and drive at
reduced speeds when roads are covered
with ice and/or snow:
Driving without proper traction devices on
snow and/or ice-covered roads is
dangerous. The Traction Control System
(TCS) alone cannot provide adequate
traction and you could still have an
accident.
NOTE
To turn off the TCS, press the TCS OFF
switch (page 4-67).
▼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
If the TCS or DSC is operating, the
indicator light flashes.

If the light stays on, the TCS, DSC or the
brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.
NOTE
In addition to the indicator light
flashing, a slight lugging sound will
come from the engine. This indicates
that the TCS/DSC is operating properly.
On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

Mazda Radar Cruise Control with Stop & Go function
(MRCC with Stop & Go function)
*
The MRCC with Stop & Go function system is designed to maintain headway control*1
with a vehicle ahead according to your vehicle's speed using a radar sensor (front) to detect
the distance to the vehicle ahead and a preset vehicle speed without you having to use the
accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead such as if the vehicle
ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a sufficient distance between the vehicles.
If the vehicle ahead stops while you are following behind it, your vehicle will stop and be
held stopped automatically (stop hold control), and headway control will resume when you
resume driving the vehicle such as by pressing the RES switch.
Also refer to the following before using the MRCC with Stop & Go function.
AUTOHOLD (page 4-59)
Forward Sensing Camera (FSC) (page 4-126)
Radar sensor (front) (page 4-131)
WA R N I N G
Do not rely completely on the MRCC with Stop & Go function:
The MRCC with Stop & Go function system has detection limitations depending on the type of
vehicle ahead and its conditions, the weather conditions, and the road conditions.
Additionally, the system may be unable to dece lerate sufficiently to avoid hitting the vehicle
ahead if the vehicle ahead applies the brakes sudd enly or another vehicle cuts into the driving
lane, which could result in an accident.
Always drive carefully and verify the surroundi ng conditions and depress the brake pedal or
accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
Do not use the MRCC with Stop & Go function system in the following locations, using the
MRCC with Stop & Go function system at the following locations may result in an unexpected
accident:
 General roads other than high ways (Driving under these conditions using the MRCC with
Stop & Go function system is not possible.)
 Roads with sharp curves and where vehicle
traffic is heavy and there is
insufficient space
between vehicles.
When Driving
i-ACTIVSENSE
4-104*Some models.
CX-3_8JL1-EA-20G_Edition1_old 2020-5-22 15:31:00

Roads where frequent and repetitive accelerati on and deceleration occur (Driving under
these conditions using the MRCC with Stop & Go function system is not possible).
 When entering and exiting interchanges, servic e 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 a ccelerate 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 ahea d 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.)
For safety purposes, switch the MRCC with Stop & Go function system off when it is not being
used.
Do not get out of the vehicle while the stop hold control is operating:
Getting out of the vehicle while the stop hold co ntrol 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 a mis-operation.
NOTE
The MRCC with Stop & Go function system do es not detect the following as physical
objects.
Vehicles approaching in the opposite direction
Pedestrians
Stationary objects (stopped vehicles, obstructions)
If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
During headway control travel, do not set the system for detection of two-wheeled
vehicles such as motorcycles and bicycles.
Do not use the MRCC with Stop & Go function system under conditions in which close
proximity warnings are frequently activated.

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.
The sound of the automatic brakes operating may be heard, however, it does not indicate
a problem.
The brake lights turn on while the MRCC with Stop & Go function automatic braking is
operating, however, they may not turn on while the vehicle is on a downslope at the set
vehicle speed or traveling at a constant speed and following a vehicle ahead.

Advanced Smart City Brake Support (Advanced SCBS)*
The Advanced SCBS alerts the driver of a possible collision using the display and a warning
sound when the Forward Sensing Camera (FSC) detects a vehicle ahead or pedestrian and
determines that a collision with the object is unavoidable while the vehicle is driven at a
vehicle speed of about 4 to 80 km/h (2 to 50 m ph) if the object is a vehicle ahead and about
10 to 80 km/h (6.2 to 50 mph) if the object is a pedestrian. In addition, the system reduces
damage in the event of a collision by operating the brake control (Advanced SCBS brake)
when the system determines that a collision is unavoidable. In addition, when the driver
depresses the brake pedal, the brakes are appl ied firmly and quickly to assist. (Brake Assist
