Toyota Yaris: ABS/TCS/DSC / 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 Your Toyota Dealer and Have Vehicle Inspected.
- 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.
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.
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...
