ABS/TCS/DSC/Trailer Stability Control (TSC)
Antilock Brake System (ABS)
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 Contact Authorized Mazda Dealer and Have Vehicle Inspected (Search).
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.
-
Braking 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.
-
The 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.
TCS/DSC Indicator Light
This indicator light stays on for a few seconds when the ignition is switched ON. If the TCS, DSC or the Trailer Stability Control (TSC) 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.
-
In addition to the indicator light flashing, a slight lugging sound will come from the engine. This indicates that the TCS/DSC is operating properly.
-
On slippery surfaces, such as fresh snow, it will be impossible to achieve high rpm when the TCS is on.
TCS OFF Indicator Light
This indicator light stays on for a few seconds when the ignition is switched ON.
It also illuminates when the TCS OFF switch is pressed and TCS is switched off.
Refer to TCS OFF Switch (Search).
If the light remains illuminated and the TCS is not switched off, take your vehicle to an Authorized Mazda Dealer. The DSC may have a malfunction.
