warning MAZDA MODEL 3 HATCHBACK 2019 (in English) Workshop Manual

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 automatically to provide
optimum power to the drive wheels,
limiting wheel spin and loss of traction.

The warning light turns on when the
system has a malfunction.
Refer to TCS/DSC Indication/Indicator
Light (Turns on) on page 7-31.
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 co uld still have an
accident.
NOTE
To turn off the TCS, press the DSC OFF
switch (page 4-77).
▼ 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 4-74) and TCS (page
4-75).

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 I ndication/Indicator
Light (Turns on) on page 7-31.
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 w ith the DSC, the Hill
Launch Assist (HLA) may not operate.
Refer to Hill Launch Assist (HLA) on page
4-72.
▼ 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.

i-ACTIV AWD Operation*
▼i-ACTIV AWD Operation
AWD provides excellent drivability on
snow-covered and ice-packed roads, sand
and mud, as well as on steep slopes and
other slippery surfaces.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Contact Authorized Mazda
Dealer and AWD Warning Indication/
Warning Light on page 7-30.
WA R N I N G
Never spin a wheel that is
off the ground:
Spinning a wheel that is off the ground as a
result of the vehicle being stuck or in a
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 veh icle 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.
▼ To w i n g
If the vehicle requires towing, have it
towed with all 4 wheels completely off the
ground.
Refer to Towing Description on page
7-22.

Power Steering
▼Power Steering
Power steering is only operable when
the engine is running. If the engine is off
or if the power steering system is
inoperable, you can still steer, but it
requires more physical effort.
If the steering feels stiffer than usual
during normal driving or the steering
vibrates, consult an Authorized Mazda
Dealer.
The warning indication notifies the
driver of system abnormalities and
operation conditions.
Refer to Power Steering Malfunction
Indication/Indicator Light on page
7-28.
CAUTION
Never hold the steering wheel to the
extreme left or right for more than 5
seconds with the engine running. This
could damage the power steering system.

i-ACTIVSENSE*
▼i-ACTIVSENSE
i-ACTIVSENSE is a collective term
covering a series of advanced safety and
driver support systems which make use of
cameras and sensors. The systems consist
of active safety and pre-crash safety
systems.
These systems are designed to assist the
driver in safer drivi
ng by reducing the load
on the driver and helping to avert
collisions or reduce their severity.
However, because each system has its
limitations, always drive carefully and do
not rely solely on the systems.
