2020 MAZDA MODEL 3 HATCHBACK warning light

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 Li
ght 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.
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.
▼ Brake Override System
The brake override system applies the
brake first for safety if the brake pedal and
accelerator pedal are depressed at the same
time.

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 w hen you start driving the vehicle.
WA R N I N G
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.
 “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 transmi ssion vehicle) and apply the parking brake.

Antilock Brake System(ABS)
▼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 ABS Warning
Indication/Warning
Light on page 7-30.
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 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.

Traction Control System(TCS)
▼Traction Control System (TCS)
The Traction Control System (TCS)
enhances traction and safety by controlling
engine torque and braking. When the TCS
detects driving wheel slippage, it lowers
engine torque and operates the brakes to
prevent loss of traction.

This means that on a slick surface, the
engine adjusts autom
atically to provide
optimum power to th e drive wheels,
limiting wheel spin a nd loss of traction.

The warning light turns on when the
system has a malfunction.
Refer to TCS/DSC I ndication/Indicator
Light (Turns on) on page 7-32.
WA R N I N G
Do not rely on the Traction Control System
(TCS) as a substitute for safe driving:
The Traction Control System (TCS) cannot
compensate for unsafe and reckless
driving, excessive speed, tailgating
(following another vehicle too closely), and
hydroplaning (reduced tire friction and
road contact because of water on the road
surface). You can still have an accident.
Use snow tires or tire chains and drive at
reduced speeds when roads are covered
with ice and/or snow:
Driving without proper traction devices on
snow and/or ice-covered roads is
dangerous. The Traction Control System
(TCS) alone cannot provide adequate
traction and you could still have an
accident.
NOTE
To turn off the TCS, press the DSC OFF
switch (page 4-78).
▼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
If the TCS or DSC is operating, the
indicator light flashes.

If the light stays on, the TCS, DSC or the
brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.
NOTE
In addition to the indicator light
flashing, a slight lugging sound will
come from the engine. This indicates
that the TCS/DSC is operating properly.
On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

Dynamic Stability Control(DSC)
▼Dynamic Stability Control (DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such as
ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.

Refer to ABS (page 4
-75) and TCS (page
4-76).

DSC operation is possible at speeds
greater than 20 km/h (12 mph).

The warning light turns on when the
system has a malfunction.
Refer to TCS/DSC Indication/Indicator
Light (Turns on) on page 7-32.
WA R N I N G
Do not rely on the Dynamic Stability
Control as a substitute for safe driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and reckless
driving, excessive speed, tailgating
(following another vehicle too closely), and
hydroplaning (reduced tire friction and
road contact because of water on the road
surface). You can still have an accident.
CAUTION
 The DSC may not operate correctly
unless the following are observed:
 Use tires of the correct size
specified for
your Mazda on all 4 wheels.
 Use tires of the same manufacturer,
brand and tread pattern on all 4
wheels.
 Do not mix worn tires.
 The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.
NOTE
If there is a problem with the DSC, the Hill
Launch Assist (HLA) may not operate.
Refer to Hill Launch Assist (HLA) on page
4-73.
▼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
If the TCS or DSC
is operating, the
indicator light flashes.

If the light stays on, the TCS, DSC or the
brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an

ditch is dangerous. The drive assembly
could be seriously damaged which could
lead to an accident or could even lead to
overheating, oil leakage, and a fire.
▼ AWD Driving
This vehicle has not been designed for the
purpose of off-road driving or rallies. Do
not attempt to drive over uneven or rocky
surfaces, or across rivers.
Although this vehicle is equipped with
AWD, acceleration, steering and braking
operations should be conducted in the
same manner as with a non-AWD vehicle,
with the emphasis placed on safe driving.
▼Tires and Tire Chains
The condition of the tires plays a large role
in the performance of the vehicle.
Moreover, to prevent adverse effects to the
drive assembly, please note the following:
Tires
When replacing tires, always replace all
front and rear tires at the same time.
All tires must be of the same size,
manufacture, brand and tread pattern.
Pay particular attention when equipping
snow or other types of winter tires.
Do not mix tread-worn tires with normal
tires.
Inspect tire inflation pressures at the
specified periods adjust to the specified
pressures.
NOTE
Check the tire inflation pressure label
attached to driver's door frame for the
correct tire inflation pressure.
Make sure to equip the vehicle with
genuine wheels of the specified size, on
all wheels. With AWD, the system is
calibrated for all 4 wheels being of the
same dimensions.
Tire chains
Install tire chains to the front tires.
Do not use tire chains on the rear
wheels.
Do not drive the vehicle faster than 30
km/h (19 mph) with the tire chains
installed.
Do not drive the vehicle with tire chains
on road conditions other than snow or
ice.
