Controls in detail Driving systems i Pressing the switch twice in quick succession will cause the vehicle to immediately raise or lower according to the starting level. The selected vehicle level setting remains stored in memory even if the engine is turned off and restarted. Normal level (see table) Speed dependent lowering of vehicle chassis (approximate values): between 0 mph (0 km/h) and 40 mph (65 km/h) - none between 40 mph (65 km/h) and 87 mph (140 km/h) - lowered progressively by approx. 0.4 in (11 mm). Raised level 1 (see table) Speed dependent lowering of vehicle chassis (approximate values) between 0 mph (0 km/h) and 38 mph (60 km/h) - raised by approx. 0.55 in (14 mm) between 38 mph (60 km/h) and 100 mph (160 km/h) - lowered progressively by approx. 0.55 in (14 mm) Raised level 2 (see table) Speed dependent lowering of vehicle chassis (approximate values): between 0 mph (0 km/h) and 18 mph (30 km/h) - raised by approx. 0.95 in (24 mm) between 18 mph (30 km/h) and 38 mph (60 km/h) - lowered progressively by approx. 0.4 in (10 mm) between 38 mph (60 km/h) and 100 mph (160 km/h) - lowered progressively by additional approx. 0.55 in (14 mm). Parktronic system* (Parking assist) Warning! G Parktronic is a supplemental system. It is not intended to, nor does it replace, the need for extreme care. The responsibility during parking and other critical maneuvers always rests with the driver. Special attention must be paid to objects with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, or road curbs). Such objects may not be detected by the system and can damage the vehicle. The operational function of the Parktronic can be affected by dirty sensors, especially at times of snow and ice, see "Cleaning the Parktronic system sensors" ( page 259). Interference caused by other ultrasonic signals (e.g. working jackhammers or the air brakes of trucks) can cause the system to send erratic indications, and should be taken into consideration. 193
