When Driving
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
 


¾ The DSC may not operate correctly
unless the following are observed:
 


¾ Use tires of the correct size specifi ed
for your Mazda on all four wheels.
 


¾ Use tires of the same manufacturer,
brand and tread pattern on all four
wheels.
 


¾ Do not mix worn tires. 



¾ 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 À ashes.

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.

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

N O T E
 


y 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 dif¿ cult. When this
happens, turn off the TCS/DSC.
 


y If the TCS/DSC is off when the engine
is turned off, it automatically activates
when the ignition is switched ON.
 


y Leaving the TCS/DSC on will provide
the best traction.
 


y 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.

 When the vehicle speed is less than
about 20 km/h (12 mph), the High Beam
Control System (HBC) switches the
headlights to low beams.
 


y The low beams may not switch to high
beams when cornering.
 


y Operation of the High Beam Control
System (HBC) function can be disabled.
