2019 MAZDA MODEL CX-30 engine

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 manoeuvring, enhancing
vehicle safety.

Refer to ABS (page 4-80) and TCS
(page 4-81).

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
7-55.
WARNING
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 tyre friction and road contact
because of water on the road surface).
You can still have an accident.
CAUTION
¾The DSC may not operate correctly
unless the following are observed:
¾Use tyres of the correct size
specified for your Mazda on all 4
wheels.
¾Use tyres of the same
manufacturer, brand and tread
pattern on all 4 wheels.
¾Do not mix worn tyres.
¾The DSC may not operate correctly
when tyre chains are used or a
temporary spare tyre is installed
because the tyre 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 4-79.
▼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
expert repairer (we recommend an
Authorised Mazda Repairer).

M Hybrid
▼M Hybrid
M Hybrid uses the Integrated Starter-Generator (ISG) with excellent power
generation efficiency to generate electricity from the kinetic energy generated when
the vehicle decelerates. The system uses the electrical power stored in the M Hybrid
battery, which is a large-capacity battery to improve driveability and fuel economy by
reducing engine load and providing motor assist. In addition, the ISG provides quiet
engine restarting after the engine is stopped by after the i-stop function (idling stop).

Drive Selection*
▼Drive Selection
Drive selection is a system to switch
the vehicle's drive mode. When the
sport mode is selected, vehicle's
response against accelerator operation
is enhanced. This provides additional
quick acceleration which may be
needed to safely make manoeuvres
such as lane changes, merging onto
freeways, or passing other vehicles.
CAUTION
Do not use the sport mode when
driving on slippery roads such as wet
or snow-covered roads. It may cause
tyre slipping.
NOTE
xWhen the sport mode is selected,
driving at higher engine speeds
increases and it may increase fuel
consumption. Mazda recommends
that you cancel the sport mode on
normal driving.
xDrive mode cannot be switched in
the following conditions:
xABS/TCS/DSC is operatingxCruise control* is operating.xThe Mazda Radar Cruise Control
(MRCC) system* is operating.xThe Mazda Radar Cruise Control

For safety purposes, switch the MRCC
system off when it is not being used.
Leaving the MRCC system turned on
when it is not in use is dangerous as it
could operate unexpectedly, resulting
in an accident.
CAUTION
¾Turn the system off when the vehicle
is running on a chassis roller.
¾If your vehicle is towed or you are
towing something , switch the MRCC
system off to prevent an unexpected
operation.
NOTE
xThe MRCC system does not detect
the following as physical objects.
xVehicles approaching in the
opposite direction
xPedestriansxStationary objects (stopped
vehicles, obstructions)
xIf a vehicle ahead is travelling at an
extremely low speed, the system
may not detect it correctly.
xIf there is a structure on the road or
an object (such as a monorail) at a
low height off the ground in front of
the vehicle, the system may operate.
Therefore, do not use the MRCC.
xDo not use the MRCC system under
conditions in which close proximity
warnings are frequently activated.
xDuring headway control travel, the
system accelerates and decelerates
your vehicle in conjunction with the
speed of the vehicle ahead.
However, if it is necessary to
accelerate for a lane change or if the
vehicle ahead brakes suddenly
causing you to close in on the vehicle
rapidly, accelerate using the
accelerator pedal or decelerate using
the brake pedal depending on the
conditions.
xWhile the MRCC system is in use, it
does not cancel even if the selector
lever (automatic transmission)/shift
lever (manual transmission) is
operated and any intended engine
braking will not occur. If deceleration
is required, lower the vehicle speed
setting or depress the brake pedal.
xWhile braking by the MRCC control
is operating, you might hear an
operation sound, however, this does
not indicate a problem.
xThe brake lights turn on while
braking by the MRCC control is
operating , however, they may not
turn on while the vehicle is on a
down slope at the set vehicle speed
or travelling at a constant speed and
following a vehicle ahead.
xStop the headway control function to
switch the system to the cruise
control function.
