ahead, and then using it for the measurement. Consequently, the Smart City Brake
Support (SCBS) may not operate under the following conditions:
Refl ection of the laser is poor due to the shape of the vehicle ahead.
The vehicle ahead is signifi cantly dirty.
Under bad weather condition, such as rain, fog and snow.

Elongated luggage or cargo is loaded onto installed roof rails and covers the laser
sensor.
Exhaust gas from the vehicle in front, sand, snow, and water vapour rising from
manholes and grating, and water splashed into the air.
When towing a malfunctioning vehicle.

In the following cases, the laser sensor may inadvertently determine that there is a
vehicle ahead and the Smart City Brake Support (SCBS) system may operate.
