NOTE
When canceling the parking brake
auto operation and parking the
vehicle, shift the shift lever to the 1st
gear or the R position for a manual
transmission, or shift the selector
lever to the P position for an
automatic transmission, and then
use wheel blocks.
The auto operation may not cancel if
the vehicle is parked on a steep
slope.
When the ignition is switched ON, the
parking brake auto operation is
restored.
▼ Warning Light
The warning light turns on when the
system has a malfunction.
Refer to Brake System Warning
Indication/Warning Light on page
7-27.
▼Brake Pad Wear Indicator
When the disc brake pads become
worn, the built-in wear indicators
contact the disc plates. This causes a
screeching noise to warn that the pads
should be replaced.
When you hear this noise, consult an
Authorized Mazda Dealer as soon as
possible.
WARNING
Do not drive with worn disc pads:
Driving with worn disc pads is
dangerous. The brakes could fail and
cause a serious accident. As soon as
you hear a screeching noise consult an
Authorized Mazda Dealer.
NOTE
In high humidity weather conditions,
brake noises, such as brake squeak or
brake squeal can be heard. It does not
indicate a malfunction.
▼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 eff ect 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 e ffect 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.

AUTOHOLD
▼AUTOHOLD
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 when 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 appropriately 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 vehicl
e not 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 position 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.
 “Depress Brake Pedal. Brake Hold Disabled” is displayed in the multi-information
display and the warning sound is activated at the same time.
Always apply the parking brake when parking the vehicle:
Not applying the parking brake when parking the vehicle is dangerous as the vehicle
may move unexpectedly and result in an accident. When parking the vehicle, shift
the selector lever to the P position (automatic transmission vehicle) and apply the
parking brake.

CAUTION
If you stop operating the accelerator pedal before the vehicle starts moving, the
force holding the vehicle in the stopped position may weaken. Firmly depress the
brake pedal or depress the accelerato r pedal to accelerate the vehicle.
NOTE
Under the following conditions, a problem with the AUTOHOLD is occurring.
Have your vehicle inspected at an Authorized Mazda Dealer as soon as possible.
A message is indicated on the multi-information display and a warning sound is
activated for about 5 seconds while the AUTOHOLD is operating or when you
press the AUTOHOLD switch.
If you switch the ignition OFF while the AUTOHOLD is operating, the parking
brake is applied automatically to assist you with parking the vehicle.
The AUTOHOLD is canceled when the selector lever/shift lever is shifted to R
position while the vehicle is on level ground , or facing up a hill or grade (as shown
below).

The ignition is switched OFF.There is a problem with the
AUTOHOLD function.
Hill Launch Assist (HLA)
▼ Hill Launch Assist (HLA)
The HLA functions to assist in
accelerating the vehicle from a stop on
slopes. When releasing the brake pedal
and depressing the accelerator pedal
to accelerate the vehicle from a stop
while on a slope, the function prevents
the vehicle from rolling. The HLA also
operates when reversing on a slope.
The braking force is maintained
automatically after releasing the brake
pedal on a steep slope.
For manual transmission vehicles, the
HLA operates when the vehicle is tilted
rearward with the shift lever in a
forward gear, and operates when the
vehicle is tilted forward with the shift
lever in the R position.
For automatic transmission vehicles,
the HLA operates when the vehicle is
tilted rearward with the selector lever
in a forward gear, and operates when
the vehicle is tilted forward with the
selector lever in the R position.
WARNING
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. In addition, for vehicles
with a manual transmission, the
vehicle could still roll depending on
how the clutch pedal or the accelerator
pedal is operated.
