2019 MAZDA MODEL CX-30 Owners Manual (in English)

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).

Charging the M Hybrid battery
The M Hybrid battery is charged
automatically by the engine power and
deceleration regeneration. Therefore, it
is not necessary to charge the battery
from outside of the vehicle.
CAUTION
Drive the vehicle for about 30 minutes
once every few months because
self-discharge occurs gradually if the
vehicle is not driven for a long period
of time. If the M Hybrid battery
becomes completely discharged and
M Hybrid cannot be activated, contact
an expert repairer (we recommend an
Authorised Mazda Repairer).
▼M Hybrid Precautions
For vehicle maintenance or repairs, or
when scrapping the vehicle, consult an
expert repairer (we recommend an
Authorised Mazda Repairer).
Handling the M Hybrid battery
Technical knowledge and skill are
necessary in handling the M Hybrid
battery.

To ensure safe and correct handling of
the M Hybrid battery, always heed the
following precautions:
¾Do not remove the M Hybrid battery.
¾Do not resell, transfer, or modify the
M Hybrid battery.
¾Do not use the battery on vehicles
other than those equipped with the
M Hybrid battery.
If the M Hybrid battery is not handled
properly, the following may occur and
cause serious injury:
¾Touching an unattended or illegally
abandoned M Hybrid battery may
cause electrocution.
¾If the M Hybrid battery is used on a
vehicle other than one equipped
with M Hybrid (including modified
vehicles), accidents such as
electrocution, heat generation,
smoking, combustion, and
explosions, or an electrolyte leakage
may occur.
Scrapping Your Vehicle and Disposing
of the M Hybrid battery
The M Hybrid battery is salvaged to
prevent accidents involving it. When
scrapping your vehicle, replacing the M
Hybrid battery, or disposing of the M
Hybrid battery, consult an expert
repairer (we recommend an
Authorised Mazda Repairer). Please
cooperate in ensuring that the vehicle's
M Hybrid battery is salvaged.
WARNING
Dispose of the M Hybrid battery
appropriately:
If the M Hybrid battery is not salvaged
and disposed of appropriately, such as
by leaving it unattended or illegally
abandoning it, some other person may
touch it which could cause
electrocution leading to serious injury.
If an Accident Occurs
If the vehicle receives an impact of a
certain level or greater in a collision, M
Hybrid may stops. In this case, the
charging system warning light turns on
and M Hybrid cannot activate. Park the
vehicle in a safe place immediately and
contact an expert repairer (we
When Driving
M Hybrid
4-88

recommend an Authorised Mazda
Repairer).
WARNING
Never touch the areas where high
current is flowing:
Never touch a M Hybrid related part.
Otherwise, it could lead to an
electrical shock or burns causing
serious injury.
Never touch electrical wiring that may
be protruding into or outside of the
cabin:
Otherwise, it could lead to an
electrical shock or burns causing
serious injury.
Never touch any area where
electrolyte is visible or electrolyte is
leaking from the area:
If any electrolyte from the M Hybrid
battery gets in the eyes or on the skin,
it could cause loss of vision or skin
reactions. In the unlikely event that
electrolyte comes into contact with the
eyes or skin, flush with large quantities
of water immediately and seek
immediate medical attention.
Do not come near the vehicle if
electrolyte is leaking from the M
Hybrid battery:
Even if the M Hybrid battery is
damaged, large quantities of
electrolyte will not flow out due to the
internal structure of the battery,
however, in the unlikely event that it
does, it will produce steam. The steam
contains properties that can irritate the
eyes and skin, and could cause acute
poisoning if absorbed.
Never approach objects that are on
fire or extremely hot:
Electrolyte in the M Hybrid battery may
cause a fire.
If the vehicle catches fire, extinguish
the fire using an ABC fire
extinguisher:
Only extinguish a fire with water when
large amounts of water is available
such as from a fire hydrant.
