▼Brake Assist
During emergency braking situations
when it is necessary to depress the brake
pedal with greater force, the brake assist
system provides braking assistance, thus
enhancing braking performance.

When the brake pedal is depressed hard or
depressed more quickly, the brakes apply
more firmly.
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.

The AUTOHOLD function automatically holds the vehicle stopped, even if you take your
foot off the brake pedal. This function can be best used while stopped in traffic or at a traffic
light. The brakes are released w hen you start driving the vehicle.
WARNING
Do not rely completely on the AUTOHOLD function:
The AUTOHOLD function is only designed to assist the brake operation while the vehicle is
stopped. Neglecting to operate the brakes and relying only on the AUTOHOLD system is
dangerous and could result in an unexpected accident if the vehicle were to suddenly move.
Operate the brakes appr opriately in accordance with the road and surrounding conditions.
Do not release your foot from the brake pedal while the vehicle is stopped on a steep grade:
Because there is a possibility of the vehicle no t being held in the stopped position by the
AUTOHOLD function, the vehicle may move unexpectedly and result in an accident.
Do not use the AUTOHOLD function on slippery roads such as icy or snow-covered roads, or
unpaved roads:
Even if the vehicle is held in the stopped posi tion by the AUTOHOLD function, the vehicle may
move unexpectedly and result in an accident. Operate the accelerator pedal, brakes, or
steering wheel appropriately as necessary.
Immediately depress the brake pedal in the following cases:
Because the AUTOHOLD function is canceled forcibly, the vehicle may move unexpectedly
and result in an accident.

Hill Launch Assist (HLA)
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. T he braking force is
maintained automatically after the brake
pedal is released on a steep grade.
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.
WA R N I N G
Do not rely completely on HLA :
HLA is an auxiliary device for accelerating
from a stop on a slope. The system only
operates for about 2 seconds and
therefore, relying only on the system, when
accelerating from a stop is dangerous
because the vehicle may move (roll)
unexpectedly and cause an accident.
The vehicle could roll depending on the
vehicle's load or if it is towing something.
Always confirm the safety around the
vehicle before starting to drive the vehicle.
NOTE
HLA does not operate on a gentle slope.
In addition, the gradient of the slope on
which the system will operate changes
depending on the vehicle's load.
HLA does not operate if the parking
brake is applied, or if the vehicle has not
stopped completely.
HLA is operating, the brake pedal may
feel stiff and vibrate, however, this does
not indicate a malfunction.

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 7-28.
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.
