Toyota Yaris: ABS/TCS/DSC / Dynamic Stability Control (DSC)

Toyota Yaris XP210 (2020-2026) Owner's Manual / 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 and TCS.

DSC operation is possible at speeds greater than 12 mph (20 km/h).

The warning light turns on when the system has a malfunction. Refer to Contact Your Toyota Dealer and Have Vehicle Inspected.

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.

NOTICE

The DSC may not operate correctly unless the following are observed:
- Use tires of the correct size specified for your Toyota on all 4 wheels.
- Use tires of the same manufacturer, brand and tread pattern on all 4 wheels.
- Do not mix worn tires.
The DSC may not operate correctly when tire chains are used or a temporary spare tire is installed because the tire diameter changes.

Traction Control System (TCS)

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 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...
