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 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.
Trailer Stability Control (TSC)
If the vehicle sways while being driven and towing a trailer, the Trailer Stability Control (TSC) automatically controls braking and engine torque to suppress the swaying and enhance vehicle stability.
The Trailer Stability Control (TSC) is operable at a vehicle speed of about 65 km/h (40 mph) or more.
When the Trailer Stability Control (TSC) operates while driving the vehicle, the TCS/DSC indicator light flashes.
Refer to TCS/DSC Indicator Light (Search).
Do not rely solely on the Trailer Stability Control (TSC)
Assured vehicle stability is limited even if the Trailer Stability Control (TSC) is operating. Drive carefully to prevent accidents.
In particular, if the TCS/DSC indicator light is flashing, drive the vehicle carefully as it is in a less stable condition and could sway more easily. Drive with caution and in accordance with the road, vehicle and trailer conditions.
-
The Trailer Stability Control (TSC) 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 Trailer Stability Control (TSC) may not operate correctly when tire chains are used or a temporary spare tire is installed because the tire diameter changes.
-
The Trailer Stability Control (TSC) uses the TCS/DSC functions. The Trailer Stability Control (TSC) does not operate if there is a malfunction in the TCS/DSC (the TCS/DSC indicator light turns on).
-
When the Trailer Stability Control (TSC) is operating, the brake lights may turn on.
-
