Brake system– While travelling in rain or snow, the front brakepads are applied periodically (every 185 seconds)to the brake discs at a minimum pressure (0.5 -1.5 bar) for a short time (approx. 2.5 seconds).This cleans the brake pads and discs, therebyimproving braking response. To do this, thewindscreen wiper must be switched on and thevehicle speed must be > 70 km/h.– The opening cross-section of the ESP switch-overvalves can now be varied by changing theactivating signal as required. (For details of howthis works, see SSP285, page 49.)As a result, the brake pressure can be regulatedmore specifically, the acoustics are improved andpulsations on the brake pedal are significantlyreduced.– The so-called ”hill holder” function is used forvehicles with Multitronic transmission. If thedriver takes his/her foot off the brake pedal afterstopping on a slope, the momentary brakingpressure is kept constant by closing the ABSoutlet valves. If the driver puts his/her foot on tothe accelerator pedal within a time period ofmax. one second, the brake is then opened if theavailable engine torque is sufficient to preventthe vehicle from rolling back.If the accelerator pedal is not pressedimmediately after letting off the brake pedal, thebrake is opened again after one second. Thisfunction helps the driver to take off again afterstopping for a short time on a slope.Unlike ”traditional” automatic gearboxes,Multitronic gearboxes do not have a creepfunction for when the vehicle is stationary andin gear.30
