When Driving
Brake
NOTE
 When the brake pedal is depressed hard
or depressed more quickly, the pedal
will feel softer but the brakes will apply
more firmly. This is a normal effect of
the brake assist operation and does not
indicate a malfunction.
 When the brake pedal is depressed
hard or depressed more quickly, a
motor/pump operation noise may be
heard. This is a normal effect of the
brake assist and does not indicate a
malfunction.
 The brake assist equipment does not
supersede the functionality of the
vehicle's main braking system.
Hill Launch Assist (HLA)
Hill Launch Assist (HLA) is a function
which assists the driver in accelerating
from a stop while on a slope. When
the driver releases the brake pedal and
depresses the accelerator pedal while
on a slope, the function prevents the
vehicle from rolling. The braking force is
maintained automatically after the brake
pedal is released on a steep grade.
For vehicles with a manual transaxle,
Hill Launch Assist (HLA) operates on a
downward slope when the shift lever is in
the reverse (R) position, and on an upward
slope when the shift lever is in a position
other than the reverse (R) position.
For vehicles with an automatic transaxle,
Hill Launch Assist (HLA) operates on a
downward slope when the selector lever
is in the reverse (R) position, and on an
upward slope when the selector lever is in
a forward gear.

When Driving
ABS/TCS/DSC
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 Warning Indication/Warning
Lights on page 4-33.
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.

When Driving
ABS/TCS/DSC
Traction Control System
(TCS)
The Traction Control 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 Warning Indication/Warning
Lights on page 4-33.
WARNING
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 DSC OFF
switch (page 4-79).
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.

*Some models.
Mazda Radar Cruise Control (MRCC)*
The Mazda Radar Cruise Control (MRCC) system is designed to maintain headway control*1
according to the vehicle speed using a radar sensor (front) to detect \
the distance to a vehicle
ahead, and by presetting the vehicle speed between 30 km/h (19 mph) an\
d 145 km/h (90
mph), the driver is freed from having to constantly use the accelerator\
or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and the ve\
hicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for ex\
ample, 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.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration.
WARNING
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always
drive carefully:
The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the driver,
and although it maintains a constant vehicle speed, or specifically, it maintains a constant
distance between your vehicle and the detected vehicle ahead according to the vehicle
speed, the 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 decelerate sufficiently to avoid hitting the vehicle ahead if the vehicle ahead
applies the brakes suddenly or another vehicle cuts into the driving lane, which could result in
an accident. Always verify the safety of the surrounding area and depress the brake pedal or
accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
 Roads with sharp curves and where vehicle traffic is heavy and there is insufficient
space between vehicles. Roads where frequent and repetitive acceleration and
deceleration occur (Driving under these conditions using the Mazda Radar Cruise
Control (MRCC) system is not possible).
 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 (The tires could spin causing you to
lose vehicle control).
 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).
For the purposes of safety, switch the Mazda Radar Cruise Control (MRCC) system off
when it is not being used.

 The following are not detected 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 on two-wheeled vehicles such as
motorcycles and bicycles.
 Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which
the 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.

Smart City Brake Support (SCBS)*
The Smart City Brake Support (SCBS) system alerts the driver of a possible collision using
an indication in the display and a warning sound when the Forward Sensin\
g Camera (FSC)
detects a vehicle ahead and determines that a collision with a vehicle a\
head is unavoidable
while the vehicle is being driven at a vehicle speed of about 4 to 80 km\
/h (2 to 50 mph).
In addition, the system reduces damage in the event of a collision by op\
erating the brake
control (SCBS brake) when the system determines that a collision is unavoidable while the
vehicle is being driven at a vehicle speed of about 4 to 30 km/h (2 to \
18 mph). It may also
be possible to avoid a collision if the relative speed between your vehi\
cle and the vehicle in
front of you is less than about 20 km/h (12 mph). In addition, when th\
e driver depresses the
brake pedal while the system is in the operation range at about 4 to 30 \
km/h (2 to 18 mph),
the brakes are applied firmly and quickly to assist. (Brake Assist (SCBS brake assist))
