Distance Alert is active at speeds above approximately 18 mph (30 km/h) and only reacts to a vehicle ahead that is driving in the same direction. No information is provided for vehicles driving toward you, moving very slowly, or at a standstill.

An warning light in the windshield glows steadily if your vehicle is closer to the one ahead than the set time interval.
If your vehicle is equipped with the optional head-up display, a symbol will appear.
Note
Distance Alert only monitors distance to the vehicle ahead while Adaptive Cruise Control is in standby mode or off.
Warning
Distance Alert only indicates the distance to the vehicle ahead. It does not affect the speed of your vehicle.
