brakes MAZDA MODEL CX-3 2021 Owners Manual

Break-In Period
No special break-in is necessary, but a few
precautions in the first 1,000 km (600
miles) may add to the performance,
economy, and life of the vehicle.
Do not race the engine.
Do not maintain one constant speed,
either slow or fast, for a long period of
time.
Do not drive constantly at full-throttle or
high engine rpm for extended periods of
time.
Avoid unnecessary hard stops.
Avoid full-throttle starts.
Saving Fuel and Protectionof the Environment
How you operate your Mazda determines
how far it will travel on a tank of fuel. Use
these suggestions to help save fuel and
reduce CO
2.
Avoid long warm-ups. Once the engine
runs smoothly, begin driving.
Avoid fast starts.
Drive at lower speeds.
Anticipate when to apply the brakes
(avoid sudden braking).
Follow the maintenance schedule (page
6-4) and have an Authorized Mazda
Dealer perform inspections and
servicing.
Use the air conditioner only when
necessary.
Slow down on rough roads.
Keep the tires properly inflated.
Do not carry unnecessary weight.
Do not rest your foot on the brake pedal
while driving.
Keep the wheels in correct alignment.
Keep windows closed at high speeds.
Slow down when driving in crosswinds
and headwinds.
WA R N I N G
Never stop the engine when going down a
hill:
Stopping the engine when going down a
hill is dangerous. This causes the loss of
power steering and power brake control,
and may cause damage to the drivetrain.
Any loss of steering or braking control
could cause an accident.

Hazardous Driving
WARNING
Be extremely careful if it is necessary to
downshift on slippery surfaces:
Downshifting into lower gear while driving
on slippery surfaces is dangerous. The
sudden change in tire speed could cause
the tires to skid. This could lead to loss of
vehicle control and an accident.
When driving on ice or in water, snow,
mud, sand, or similar hazards:
Be cautious and allow extra distance for
braking.
Avoid sudden braking and sudden
maneuvering.
Do not pump the brakes. Continue to
press down on the brake pedal.
Refer to Antilock Brake System (ABS)
on page 4-65.
If you get stuck, select a lower gear and
accelerate slowly. Do not spin the front
wheels.
For more traction in starting on slippery
surfaces such as ice or packed snow, use
sand, rock salt, chains, carpeting, or
other nonslip material under the front
wheels.
NOTE
Use snow chains only on the front wheels.
Floor Mat
We recommend the use of Genuine
Mazda floor mats.
WA R N I N G
Make sure the floor mats are hooked on the
retention pins to prevent them from
bunching up under the foot pedals:
Using a floor mat that is not secured is
dangerous as it will interfere with the
accelerator and brake pedal operation,
which could result in an accident.
Do not install two floor mats, one on top of
the other, on the driver's side:
Installing two floor mats, one on top of the
other, on the driver's side is dangerous as
the retention pins can only keep one floor
mat from sliding forward.
Loose floor mat(s) will interfere with the
foot pedals and could result in an accident.
If using an all-weather mat for winter use
always remove the original floor mat.
When setting a floor mat, position the
floor mat so that its grommets are inserted
over the pointed end of the retention posts.

Drive slowly. Braking performance can
be adversely affected if snow or ice
adheres to the brake components. If this
situation occurs, drive the vehicle
slowly, releasing the accelerator pedal
and lightly applying the brakes several
times until the brake performance
returns to normal.
▼Snow Tires
Use snow tires on all 4 wheels
Do not go faster than 120 km/h (75 mph)
while driving with snow tires. Inflate snow
tires 30 kPa (0.3 kgf/cm
2, 4.3 psi) more
than recommended on the tire pressure
label (driver's door frame), but never more
than the maximum cold-tire pressure
shown on the tires.

Mexico
The vehicle is originally equipped with
summer tires desi gned for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
Except Mexico
The vehicle is originally equipped with all
season radials designed to be used all year
around. In some extreme climates you
may find it necessary to replace them with
snow tires during the winter months to
further improve traction on snow and ice
covered roads.
WA R N I N G
Use only the same size and type tires (snow,
radial, or non-radial) on all 4 wheels:
Using tires different in size or type is
dangerous. Your vehicle's handling could
be greatly affected and result in an
accident.
CAUTION
Check local regulations before using
studded tires.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using
tires with steel wire reinforcement in the
sidewalls (page 4-141).
▼ Tire Chains
Check local regulations before using tire
chains.
CAUTION

Chains may affect handling.
 Do not go faster than 50 km/h (30 mph)
or the chain manufacturer's
recommended limit, whichever is lower.
 Drive carefully and avoid bumps, holes,
and sharp turns.
 Avoid locked-wheel braking.
 Do not use chains on a temporary spare
tire; it may result in damage to the
vehicle and to the tire.
 Do not use chains on roads that are free
of snow or ice. The tires and chains could
be damaged.

Chains may scratch or chip aluminum
wheels.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using
tire chains.
Install the chains on the front tires only.
Do not use chains on the rear tires.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. If your vehicle is equipped with wheel covers remove them, otherwise the
chain bands will scratch them.
2. Secure the chains on the front tires as
tightly as possible.
Always follow the chain
manufacturer's instructions.
3. Retighten the chains after driving 1/2―1 km (1/4 ―1/2 mile).
Driving In Flooded Area
WA R N I N G
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
affected.
CAUTION
Do not drive the vehicle on flooded roads
as it could cause short circuiting of
electrical/electronic parts, or engine
damage or stalling from water absorption.
If the vehicle has been immersed in water,
consult an Authorized Mazda Dealer.

on the slightest incline unless the parking
brake or brakes are on.
WARNING
If the engine is running faster than idle, do
not shift from N or P into a driving gear:
It's dangerous to shift from N or P into a
driving gear when the engine is running
faster than idle. If this is done, the vehicle
could move suddenly, causing an accident
or serious injury.
Do not shift into N when driving the
vehicle:
Shifting into N while driving is dangerous.
Engine braking cannot be applied when
decelerating which could lead to an
accident or serious injury.
CAUTION
Do not shift into N when driving the
vehicle. Doing so can cause transaxle
damage.
NOTE
Apply the parking brake or depress the
brake pedal before moving the selector
lever from N position to prevent the
vehicle from moving unexpectedly.
D (Drive)
D is the normal driving position. From a
stop, the transaxle wi ll automatically shift
through a 6-gear sequence.
M (Manual)
M is the manual shift mode position.
Gears can be shifted up or down by
operating the selector lever. Refer to
Manual Shift Mode on page 4-32.
▼ Shift Position Indication
The selector position is indicated when the
ignition is switched ON.
Gear position indication
In manual shift mode, the “M” of the shift
position indication illuminates and the
numeral for the selected gear is displayed.
▼Active Adaptive Shift (AAS)
Active Adaptive
Shift (AAS)
automatically controls the transaxle shift
points to best suit the road conditions and
driver input. This improves driving feel.
The transaxle may switch to AAS mode
when driving up and down slopes,
cornering, driving at high elevations, or
depressing the accelerator pedal quickly
while the selector lever is in the D
position. Depending on the road and
driving conditions/ve hicle operations, gear
shifting could be delayed or not occur,
however, this does not indicate a problem
because the AAS mode will maintain the
optimum gear position.

Driving Tips
WARNING
Do not let the vehicle move in a direction
opposite to the direction selected by the
selector lever:
Do not let the vehicle move backward with
the selector lever in a forward position, or
do not let the vehicle move forward with
the selector lever in the reverse position.
Otherwise, the engine may stop, causing
the loss of the power brake and power
steering functions, and make it difficult to
control the vehicle which could result in an
accident.
Passing
For extra power when passing another
vehicle or climbing steep grades, depress
the accelerator fully. The transaxle will
shift to a lower gear, depending on vehicle
speed.
NOTE
(Some models)
The accelerator pedal may initially feel
heavy as it is being depressed, then feel
lighter as it is depressed further. This
change in pedal force aids the engine
control system in determining how much
the accelerator pedal has been
depressed for performing kickdown, and
functions to control whether or not
kickdown should be performed.
While the selector lever is in the M
position and the TCS is turned off,
manual shift mode does not switch to
automatic shift mode even if the
accelerator pedal is completely
depressed. Operate the selector lever.
Climbing steep grades from a stop
To climb a steep grade from a stopped
position:
1. Depress the brake pedal.
2. Shift to D or M1, depending on the load weight and grade steepness.
3. Release the brake pedal while gradually accelerating.
Descending steep grades
When descending a steep grade, shift to
lower gears, depending on load weight and
grade steepness. Descend slowly, using the
brakes only occasionally to prevent them
from overheating.

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 engine stalled or
turned
off,
find a safe place to stop:
Coasting with the engi ne stalled or turned
off is dangerous. Braking will require more
effort, 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
affected.
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
affect 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 insufficient braking
operation.

Wear shoes appropriate for driving in
order to avoid your shoe contacting the
brake pedal when depressing the
accelerator pedal.

▼Warning Light
The warning light turns on when the
system has a malfunction.
Refer to Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-29.
▼Brake Pad Wear Indicator
When the disc brake pads become worn,
the built-in wear i
ndicators 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.
WA R N I N G
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 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.

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 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.
 The brake pedal operation demand warning light (red) flashes and the warning sound is
activated at the same time.
