Antilock Brake System(ABS)
▼Antilock Brake System (ABS)
The ABS control unit continuously
monitors the speed o
f 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 brak e 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 7-29.
WA R N I N G
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 wi ll 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.

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.)
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
 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.)
For safety purposes, switch the MRCC
system off when it is not being used.
CAUTION
If your vehicle is towed or you are towing
something, switch the MRCC system off to
prevent an unexpected operation.
NOTE
The MRCC system does 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.
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.
Do not use the MRCC 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 system is in use, it
does not cancel even if the shift lever is
operated and any intended engine
braking will not occur. If deceleration is
required, lower the vehicle speed setting
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 tu
rn on while the
MRCC automatic braking is operating.

▼Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function)
The MRCC with St
op & Go function
system is designed to maintain headway
control
*1 with a vehicle ahead according
to your vehicle's speed using a front radar
sensor 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, y our vehicle will stop
and be held stopped automatically (stop
hold control), and he adway control will
resume when you resume driving the
vehicle such as by pressing the RES
switch.

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 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 drive carefully and verify the
surrounding conditions and depress the
brake pedal or accelerator pedal while
keeping a safe 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 highways
(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.
Roads where frequent and repetitive
acceleration and deceleration occur
(Driving under these conditions using the
MRCC with Stop & Go function 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 (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.
 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
