170 Starting and driving Saab Parking Assistance 1 WARNING Responsibility always lies with the driver when reversing. IB1299 IB1300 • Saab Parking Assistance can facilitate reversing at low speeds, such as when reverse parking. • Bear in mind that small and/or narrow objects cannot always be detected by the system. The parking aid system facilitates parking and reversing. There are four sensors in the rear bumper that detect objects up to 6 feet (1.8 metres) behind the car. Area monitored by the sensors seen from the side The system uses four sensors in the rear bumper. These emit ultrasound signals that bounce back to the sensors off any objects behind the car. The system, however, cannot always detect small or narrow objects or objects that do not reflect ultrasound back towards the car, such as pipes, or the corner of a house or rectangular post. Area monitored by the sensors seen from above The system is activated automatically when reverse is engaged or selected. When the sensors detect an object within the monitored area, the SID will display the text "PARK ASSIST" and pulses of sound will be heard. The frequency of the pulses increases as the car comes closer to the object. When the distance to the object is less than 12 in. (30 cm), a continuous tone will be heard.
