ABS/TCS/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 4-65 ) and TCS
(page 4-66 ).
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 Warning Indication/Warning
Lights on page 4-26 .
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 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.

ABS/TCS/DSC DSC OFF Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
It also illuminates when the DSC OFF
switch is pressed and TCS/DSC is
switched off.
Refer to DSC OFF Switch on page 4-68 .
If the light remains illuminated and the
TCS/DSC is not switched off, take your
vehicle to an Authorized Mazda Dealer.
The DSC may have a malfunction.
DSC OFF SwitchPress the DSC OFF switch to turn off the
TCS/DSC. The DSC OFF indicator light
in the instrument cluster will illuminate.
Press the switch again to turn the TCS/
DSC back on. The DSC OFF indicator
light will turn off. NOTE 
When DSC is on and you attempt to free
the vehicle when it is stuck, or drive
it out of freshly fallen snow, the TCS
(part of the DSC system) will activate.
Depressing the accelerator will not
increase engine power and freeing
the vehicle may be difficult. When this
happens, turn off the TCS/DSC. 
If the TCS/DSC is off when the engine
is turned off, it automatically activates
when the ignition is switched ON. 
Leaving the TCS/DSC on will provide
the best traction. 
If the DSC OFF switch is pressed and
held for 10 seconds or more, the DSC
OFF switch malfunction detection
function operates and the DSC system
activates automatically. The DSC OFF
indicator light turns off while the DSC
system is operative.

Depending on the driving conditions
when sport mode is selected, the vehicle
may perform shift-down or slightly
accelerate. Select Mode Indication When the sport mode is selected, the select
mode indication turns on in the instrument
cluster.

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 light notifies the driver
of system abnormalities and operation
conditions.
Refer to Warning Indication/Warning
Lights on page 4-26 .
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
*Some models. i-ACTIVSENSE *
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forward Sensing Camera (FSC) and ra dar sensors.
Because each system has its limitations, always drive carefully and do not rely solely on the
systems.

Camera and SensorsForward sensing camera (FSC)
The Forward Sensing Camera (FSC) determines the conditions ahea d of the vehicle while
traveling at night and detects traffic lanes. The following systems also use the Forward
Sensing Camera (FSC). 
High Beam Control system (HBC) 
Lane Departure Warning System (LDWS)
The Forward Sensing Camera (FSC) is installed at the top of the windshield near the
rearview mirror.
Refer to Forward Sensing Camera (FSC) on page 4-95 .
Radar sensors (rear)

*Some models.High Beam Control System (HBC) *
The High Beam Control System (HBC) determines the conditions in front of the vehicle
using the Forward Sensing Camera (FSC) while driving in darknes s to automatically switch
the headlights between high and low beams.
Refer to Warning/Indicator Lights on page 4-18 .
While driving the vehicle at a speed of about 30 km/h (19 mph) or more, the headlights are
switched to high beams when there are no vehicles ahead or approaching in the opposite
direction.
The system switches the headlights to low beams when one of the following occurs: 
The system detects a vehicle or the headlights/lights of a vehicle approaching in the
opposite direction. 
The vehicle is driven on roads lined with streetlamps or on roads in well-lit cities and
towns. 
The vehicle is driven at less than about 20 km/h (12 mph).
Forward Sensing
Camera (FSC)The recognition distance of the
Forward Sensing Camera (FSC)
varies according to the
surrounding conditions.
The warning light turns on when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-26 .
CAUTION 
Do not adjust the vehicle height, modify the headlight units, or remove the camera,
otherwise the system will not operate normally. 
Do not rely excessively on the High Beam Control System (HBC) and drive the vehicle while
paying sufficient attention to safety. Switch the headlights between the high beams and
low beams manually if necessary.

between high and low beams according to the visibility as well as road and traffic
conditions. 
When there are sources of light in the area such as street lamps, illuminated signboards,
and traffic signals. 
When there are reflective objects in the surrounding area such as reflective plates and
signs. 
