04 Driver supportCollision Warning with Auto Brake & Pedestrian Protection* 04178* Option/accessory, for more information, see Introduction.For the sensors to work correctly, they must bekept clear of dirt, ice and snow, and be cleanedregularly with water and car shampoo.NOTEDirt, ice and snow covering the sensors willreduce their function and may preventmeasurement.LimitationsCollision Warning with Auto Brake and Pedes-trian Detection is active from approx. 4 km/h.The visual warning signal (no. [1] in the illustra-tion on page 174) may be difficult to notice inthe event of strong sunlight, reflections, whensunglasses are being worn or if the driver is notlooking straight ahead. The warning soundshould therefore always be activated.On slippery road surfaces the braking distanceis extended, which may reduce the capacity toavoid a collision. In such situations the ABSand DSTC systems will provide best possiblebraking force with maintained stability.NOTEThe visual warning signal can be temporarilydisengaged in the event of high passengercompartment temperature caused bystrong sunlight for example. If this occursthen the warning sound is activated even ifit is deactivated in the menu system.•Warnings may not appear if the dis-tance to the vehicle in front is small or ifsteering wheel and pedal movementsare large, e.g. a very active driving style.WARNINGWarnings and brake interventions could beimplemented late or not at all if the trafficsituation or external influences mean thatthe radar or camera sensor cannot detect apedestrian or a vehicle in front correctly.The sensor system has a limited range forpedestrians and the system therefore pro-vides effective warnings and brake inter-ventions at vehicle speeds up to 50 km/h.For stationary or slow-moving vehicles,warnings and brake interventions are effec-tive at vehicle speeds up to 70 km/h.Warnings for stationary or slow-movingvehicles could be disengaged due to dark-ness or poor visibility.Warnings and brake interventions forpedestrians are switched off at vehiclespeeds exceeding 80 km/h.The collision warning system uses the sameradar sensors as adaptive cruise control. Formore information on the radar sensor and itslimitations, see page 179.If warnings are perceived as being too frequentor disturbing then the warning distance can bereduced. This then leads to the system provid-ing a warning at a later stage, which reducesthe total number of warnings; see the section"Set warning distance" on page 177.
