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 4-64) and TCS (page
4-65).

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 7-36.
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.
▼ 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.

Blind Spot Monitoring (BSM)*
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on
both sides during lane changes by alerting the driver to the pr esence of vehicles approaching
from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while traveling in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and turns o n the BSM warning lights
equipped on the door mirrors depending on the conditions. If th e turn signal lever is
operated to signal a lane change in the direction in which the BSM warning light is
illuminated, the system warns the driver of a vehicle in the de tection area by flashing the
BSM warning light and activating a beep sound.
The detection area on this system covers the driving lanes on b oth sides of the vehicle and
from the rear part of the doors to about 50 m (164 ft) behind t he vehicle.
