Attention: The assistance systems described below do not relieve the driver of the need to pay attention while driving, especially when reversing. Some objects that are thin, less than 30 cm away, or above or below the detection range of the sensors may not be detected and damage the vehicle. Ultrasonic waves at the frequency of the sensors, heavy precipitation and / or other conditions in which wave distortion occurs (e.g. heavy rain), can interfere with the ability of the sensors to detect obstacles. In addition, due to unfavorable surface characteristics, ultrasonic absorbing objects are not always detected. In some cases, water on the sensors of the parking assistance system may be mistaken for an obstacle. Uneven asphalt or cobblestones can lead to false alarms of the sensors.
Parking assistance
Depending on the equipment, a parking assistance system can be installed (rear or front and rear) with acoustic or visual indication. On models with a graphical instrument cluster display, the tone of the warning sounds can be adjusted via its menu.
The rear parking assistance system uses ultrasonic sensors in the rear bumper to operate (see illustration 17.1). If front and rear parking assistance is installed, sensors are also installed in the front bumper (see illustration 17.2). Each bumper can be fitted with 4 sensors: with Parking Pilot, two additional side sensors are installed in the front bumper. The ultrasonic waves emitted by the sensors are reflected from obstacles. At the subsequent hit of waves back to the sensor, the distance to obstacles is determined. The front sensors detect an obstacle up to 120 cm forward and the rear sensors detect an obstacle up to 160 cm in the rear. Keep the sensors clean for proper system operation. When washing, it is allowed to direct a jet of water under high pressure at the sensors from a distance of no more than 10 cm and only for a short time.

17.3 Parking assist display
The parking assistance system is switched on/off automatically when reverse gear is engaged/disengaged if the ignition is on. On models with front sensors, there is an additional button on the center console to turn on the system " " (30 in illustration 12.1) with power indicator. Successful activation of the system is accompanied by a short beep. If the signal is given within 3 seconds after the reverse gear is engaged, and there are no obstacles near the car, then the system is faulty. A system malfunction is additionally indicated by the flashing of the indicator in the key (in the presence of). On models with front sensors, the system is turned off automatically when accelerating to a speed of more than 10 km / h. When connecting the trailer's electrical wiring to the connector of the standard tow hitch, the sensors in the rear bumper do not turn on; in some equipment versions, the image of the trailer appears on the display of the audio/navigation system.
When the parking assist system is on, it will not beep when the DSG mode selector lever is in the "R".
On models with acoustic signaling, an intermittent sound signal is given when an obstacle is detected. As the obstacle is approached, the duration of the pauses of this signal decreases, and at a critical approach, a continuous signal sounds. On models without standard drawbar (TSU) the critical distance is 30 cm, and on models with a standard drawbar, this distance is increased by 5 cm.
If there is a standard audio / navigation unit of a certain model, its display can display a visual indication of the data coming from the sensors, and using the audio / navigation system, you can set their volume to mute when the parking assistance system is turned on. The closer the vehicle is to the obstacle, the closer the corresponding segment is to the vehicle image. The display of the penultimate segment means that the collision zone has been reached. The red segment on the color display lights up at a critical distance to an obstacle.
Parking Pilot "Park Assist"
Parking Pilot is designed to assist the driver in finding and entering a suitable free parking space. The parking space must be at least 1.4 m longer than the length of the vehicle (see subsection above), which provides the driver with assistance when entering a parking space.
In addition to the particularities of using the parking aid, the following points should be kept in mind when using the parking aid.
- The parking assist is based on parked vehicles and does not take into account the position of curbs and other conditions, so be careful not to damage the wheels.
- The accuracy of the estimation of the parking space gap can be affected by an erroneous signal of the air temperature overboard (from the corresponding sensor), for example, due to the strong influence of thermal radiation from the engine.
- Parking Pilot cannot provide automatic parking on tight curves.
- If the parking aid becomes less effective after a wheel change, it must be adapted to the new wheel circumference. Adaptation occurs automatically while driving.
When connecting the trailer wiring to the connector of the standard tow hitch, the parking autopilot does not turn on.
Follow these steps to prepare for parking.
- Make sure the ESP system is on (K/L ESP off).
- Moving at a distance of 0.5-2 m along parked cars at a speed of no more than 30 km/h, press the button " " park assist (29 in illustration 12.1), - the autopilot indication appears on the display in the instrument cluster, and the indicator in the button lights up.
- If you press the autopilot button at speeds between 30 and 50 km/h, the instrument cluster display will show an overspeed message to register a free parking space. The autopilot indication will appear when the speed drops below 30 km/h. If the speed exceeds 50 km/h, the indication must be reactivated by pressing the autopilot button again.
- After turning on the autopilot, the search for a free parking space is performed on both sides of the car, but by default, the indication is displayed only for the right side. If you intend to park on the left side of the road, turn on your left turn signals.
- If a free parking spot is found, its parameters are memorized and stored until another suitable gap is found or until the distance from the first spot exceeds 10 m. information about whether this place is suitable for parking is displayed.
To park, follow the steps below for 3 minutes.
- As soon as the park assist detects a free parking space during the above steps, the display will show (And in illustration 17.3). After that, you should continue driving until the indication appears (IN).
- After the indication (IN) stop the vehicle for about a second, and then engage reverse gear.
- As soon as the message appears on the display "Automatic taxiing. Look around!", release the steering wheel, the system takes over the steering.
- Carefully watching the surrounding area, start reversing at a speed of no more than 7 km / h. If it is not possible to complete the parking at one time, it continues with further actions.
- If the display shows (WITH), engage a forward gear and, carefully watching the surrounding area, start moving forward at a speed of no more than 7 km/h. If after that the parking is not completed again, it continues with further actions.
- If the display shows (D) Engage reverse gear, and, carefully watching the surrounding area, start moving forward at a speed of no more than 7 km / h.
- The actions described in the last two paragraphs can be repeated several times. Complete the parking maneuver according to the information from the parking assistance system. As soon as parking is completed, an audible signal sounds and the display shows the message "Auto steering completed. Take control!"
The park assist will disengage if any of the following occurs:
- the parking aid button is pressed;
- the speed when searching for a free place exceeded 30 km/h;
- parking speed exceeded 7 km/h;
- time is up (3 minutes) for parking;
- the parking assistance system has been activated;
- the ASR function is disabled;
- the driver prevents the steering wheel from turning, or turns it himself;
- if it is necessary to move in reverse, the DSG selector lever is moved out of position "R".
The following are descriptions of the possible parking assist messages that can be displayed on the instrument cluster display.
