Distance & Speed Alert (DSA)

The DSA is a system which provides advice for maintaining the appropriate distance between vehicles and notifies the driver of the recommended, safe distance to maintain with a vehicle ahead. The system measures the distance between your vehicle and a vehicle ahead while the vehicle speed is about 30 km/h (19 mph) or faster. If the distance between your vehicle and the vehicle ahead is continuously close, the system alerts the driver of a possible collision using an indication on the display and suppresses your vehicle speed*1 to prevent it from approaching the vehicle ahead too closely.

  1. The function which suppresses your vehicle speed is not available in some markets.

 

Do not rely completely on the DSA:

The ability of the system to detect a vehicle ahead is limited depending on the type of vehicle ahead, weather conditions, or traffic conditions. In addition, the system is not for maintaining the distance between your vehicle and a vehicle ahead. If you neglect to operate the accelerator and brake pedals correctly, it could lead to an accident. Always check the safety of the surrounding area and depress the brake pedal or accelerator pedal while keeping a safe distance from vehicles ahead or on-coming vehicles.
