Distance & Speed Alert (DSA)
Distance & Speed Alert (DSA) (Some Models)
The DSA is a system in which the screen display notifies the driver that the distance between your vehicle and a vehicle ahead is close.

Warnings and Cautions for Using the Distance & Speed Alert (DSA)
Do not rely completely on the DSA.
The DSA may not be able to detect a vehicle ahead depending on the type of vehicle ahead and its conditions, the weather conditions, and the road 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 surrounding conditions and depress the brake pedal or accelerator pedal while keeping a safe distance from a vehicle ahead or a vehicle following behind you.
How to Use the Distance & Speed Alert (DSA)
Operating the DSA
The DSA operates when the system determines that the distance between your vehicle and the vehicle ahead is close at a speed of about 30 km/h (19 mph) or faster.
When the DSA operates, the screen display notifies the driver that the distance between your vehicle and a vehicle ahead is close.
