MAZDA MODEL MX-30 EV 2022 Owners Manual

Brake System
▼Foot Brake
This vehicle has power-assisted brakes
that adjust automatically through
normal use.

Should power-assist fail, you can stop
by applying greater force than normal
to the brake pedal. But the distance
required to stop will be greater than
usual.
WARNING
Do not coast with the EV system
stopped and stop the vehicle in a safe
place:
Coasting the vehicle with the EV
system stopped is dangerous. Braking
will require more
eff ort, and the
brake's power-assist could be
depleted if you pump the brake. This
will cause longer stopping distances or
even an accident.
Shift to a lower gear when going
down steep hills:
Driving with your foot continuously on
the brake pedal or steadily applying
the brakes for long distances is
dangerous. This causes overheated
brakes, resulting in longer stopping
distances or even total brake failure.
This could cause loss of vehicle control
and a serious accident. Avoid
continuous application of the brakes.
Dry off brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been
a ff ected.
CAUTION
 Do not drive with your foot held on
the brake pedal. Doing so could
result in the following:
 The brake parts will wear out more
quickly.
 The brakes can overheat and
adversely
aff ect brake
performance.
 Always depress the brake pedal with
the right foot. Applying the brakes
with the unaccustomed left foot
could slow your reaction time to an
emergency situation resulting in
insu fficient braking operation.
 Wear shoes appropriate for driving in
order to avoid your shoe contacting
the brake pedal when depressing the
accelerator pedal.
▼ Electric Parking Brake (EPB)
The EPB system applies the parking
brake using an electric motor. The
system can operate automatically and
manually.
The EPB switch indicator light turns on
when applying the parking brake and it

▼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.
▼ Brake Override 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 and apply the parking brake.

Emergency Stop SignalSystem
▼Emergency Stop Signal System
If you apply the brakes suddenly while
driving at a speed of about 55 km/h
(34 mph) or faster, the emergency stop
signal system automatically and rapidly
fl
ashes all the turn signal lights to
caution drivers behind your vehicle of
the sudden braking situation.
NOTE
Flashing
When you bring your vehicle to a
complete stop while all the turn
signal lights are flashing rapidly, the
rapid flashing of all the turn signal
lights changes back to the normal
fl ashing pattern. The turn signal lights
turn o ff when you release your foot
from the brake pedal.
Operation
When the ABS operates, the
emergency stop signal system is
more likely to operate. Therefore, if
the brake pedal is depressed on a
slippery road, all of the turn signal
lights may flash.
The emergency stop signal system
does not operate when the hazard
warning light switch is pressed.
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.
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.
Always con firm 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.
