2019 MAZDA MODEL CX-3 engine

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 4-67) and TCS (page
4-68).

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 Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-30.
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 four wheels.
 Use tires of the same manufacturer,
brand and tread pattern on all four
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.
▼ 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.

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 mak e maneuvers such as lane
changes, merging onto freeways, or passing other vehicles.
CAUTION
Do not use the sport mode when driving on slip pery roads such as wet or snow-covered roads.
It may cause tire slipping.
NOTE
•When 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.
•Drive mode cannot be switched in the following conditions:
•ABS/TCS/DSC is operating
•The Mazda Radar Cruise Control with St op & Go function (MRCC with Stop & Go
function) System/cruise control is operating.
•Steering wheel is being operated abruptly
▼ Drive Selection Switch
Press the drive selection switch forward
(“
”) to select the sport mode.
Pull the drive selection switch back

•Depending on the driving conditions
when sport mode is selected, the vehicle
may perform shift-down or slightly
accelerate.
▼ Select Mode Indicator Light
When the sport mode is selected, the select
mode indicator light turns on in the
instrument cluster.

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 light not ifies the driver of
system abnormalities and operation
conditions.
In addition, the buzzer may also activate
depending on the system abnormality or
operation condition.
Refer to Stop Vehicle in Safe Place
Immediately on page 7-27.
Refer to Power Steering Warning
Buzzer on page 7-46.
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.

•During 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.
•While the MRCC with Stop & Go function system is in use, it does not cancel even if the
selector lever is operated and any intended engine braking does not occur. If deceleration
is required, lower the set speed or depress the brake pedal.
•The sound of the automatic brakes operating may be heard, however, it does not indicate
a problem.
•The brake lights turn on while the MRCC with Stop & Go function automatic braking is
operating, however, they may not turn on while the vehicle is on a downslope at the set
vehicle speed or traveling at a constant speed and following a vehicle ahead.
