■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will operate:
■Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
■Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and hill-start assist control systems
■Active Cornering Assist operation sounds and vibrations
When the Active Cornering Assist is operated, operation sounds and vibrations may be generated from the brake system, but this is not a malfunction.
■Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automatically re-enabled in the following situations:
■Operating conditions of Active Cornering Assist
The system operates when the following occurs.
■Secondary Collision Brake operating conditions
The system operates when the SRS airbag sensor detects a collision while the vehicle is in motion.
However, the system does not operate in any of the following situations.
■Secondary Collision Brake automatic cancellation
The Secondary Collision Brake is automatically canceled in the following situations:
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from overheating when there is frequent steering input over an extended period of time. The steering wheel may feel heavy as a result.
Should this occur, refrain from excessive steering input or stop the vehicle and turn the engine off. The EPS system should return to normal within 10 minutes.
■If a message about AWD is shown on the multi-information display
Perform the following actions.
■The ABS does not operate effectively when
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle's stopping distance. Always maintain a safe distance from the vehicle in front of you, especially in the following situations:
■TRAC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road surfaces, even if the TRAC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
■Active Cornering Assist does not operate effectively when
■Hill-start assist control does not operate effectively when
■When the TRAC/VSC is activated

As these are the systems to help ensure vehicle stability and driving force, do not turn the TRAC/VSC systems off unless necessary.
■Secondary Collision Brake
Do not overly rely solely upon the Secondary Collision Brake. This system is designed to help reduce the possibility of further damage due to a secondary collision, however, that effect changes according to various conditions.
Overly relying on the system may result in death or serious injury.
Make sure that all tires are of the specified size, brand, tread pattern and total load capacity. In addition, make sure that the tires are inflated to the recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires are installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may cause a system to malfunction.
