When Driving -> ABS/TCS/DSC for Your Mazda 3 4 Door Third Generation (2014-2018)

When Driving  
ABS/TCS/DSC  
NOTE  
Antilock Brake System  
(ABS)  
yBraking distances may be longer on  
loose surfaces (snow or gravel, for  
example) which usually have a hard  
foundation. A vehicle with a normal  
braking system may require less  
distance to stop under these conditions  
because the tires will build up a wedge  
of surface layer when the wheels skid.  
yThe sound of the ABS operating may  
be heard when starting the engine  
or immediately after starting the  
vehicle, however, it does not indicate a  
malfunction.  
The ABS control unit continuously  
monitors the speed of each wheel. If  
one wheel is about to lock up, the ABS  
responds by automatically releasing and  
reapplying that wheel's brake.  
The driver will feel a slight vibration in  
the brake pedal and may hear a chattering  
noise from the brake system. This is  
normal ABS system operation. Continue to  
depress the brake pedal without pumping  
the brakes.  
The warning light turns on when the  
system has a malfunction.  
Refer to Warning Lights on page 4-21.  
WARNING  
Do not rely on ABS as a substitute for  
safe driving:  
The ABS cannot compensate for unsafe  
and reckless driving, excessive speed,  
tailgating (following another vehicle  
too closely), driving on ice and snow,  
and hydroplaning (reduced tire friction  
and road contact because of water on  
the road surface). You can still have an  
accident.

When Driving  
ABS/TCS/DSC  
NOTE  
Traction Control System  
(TCS)  
To turn off the TCS, press the DSC OFF  
switch (page 4-81).  
The Traction Control System (TCS)  
enhances traction and safety by controlling  
engine torque and braking. When the TCS  
detects driving wheel slippage, it lowers  
engine torque and operates the brakes to  
prevent loss of traction.  
TCS/DSC Indicator Light  
This means that on a slick surface, the  
engine adjusts automatically to provide  
optimum power to the drive wheels,  
limiting wheel spin and loss of traction.  
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.  
The warning light turns on when the  
system has a malfunction.  
Refer to Warning Lights on page 4-21.  
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.  
WARNING  
Do not rely on the Traction Control  
System (TCS) as a substitute for safe  
driving:  
NOTE  
yIn addition to the indicator light  
flashing, a slight lugging sound will  
come from the engine. This indicates  
that the TCS/DSC is operating properly.  
yOn slippery surfaces, such as fresh  
snow, it will be impossible to achieve  
high rpm when the TCS is on.  
The Traction Control System (TCS)  
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.  
Use snow tires or tire chains and drive at  
reduced speeds when roads are covered  
with ice and/or snow:  
Driving without proper traction devices  
on snow and/or ice-covered roads  
is dangerous. The Traction Control  
System (TCS) alone cannot provide  
adequate traction and you could still  
have an accident.

When Driving  
ABS/TCS/DSC  
Dynamic Stability  
Control (DSC)  
CAUTION  
¾ꢀ  
The DSC may not operate correctly  
unless the following are observed:  
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.  
¾ꢀ  
Use tires of the correct size speciꢀed  
for your Mazda on all four wheels.  
¾ꢀ  
Use tires of the same manufacturer,  
brand and tread pattern on all four  
wheels.  
¾ꢀ  
Do not mix worn tires.  
¾ꢀ  
Refer to ABS (page 4-78) and TCS (page  
4-79).  
The DSC may not operate correctly when  
tire chains are used or a temporary spare  
tire is installed because the tire diameter  
changes.  
DSC operation is possible at speeds  
greater than 20 km/h (12 mph).  
TCS/DSC Indicator Light  
The warning light turns on when the  
system has a malfunction.  
Refer to Warning Lights on page 4-21.  
WARNING

Control as a substitute for safe driving:

because of water on the road surface).  
You can still have an accident.  
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

When Driving  
ABS/TCS/DSC  
NOTE  
DSC OFF Indicator Light  
yWhen 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.  
yIf the TCS/DSC is off when the engine  
is turned off, it automatically activates  
when the ignition is switched ON.  
yLeaving the TCS/DSC on will provide  
the best traction.  
yIf 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.  
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 4-81.  
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 Switch  
Press 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.
