The concept

Cruise control

The system is functional at speeds beginning at approx. 20 mph/30 km/h .

It maintains the speed that was set using the control elements on the steering wheel.

The system brakes on downhill gradients if engine braking action is insufficient.

General information

Depending on the set driving program, the characteristics of the cruise control can change in certain areas.

The following parking assist systems provide assistance with parking and maneuvering:

PDC Park Distance Control

The concept

PDC Park Distance Control

PDC support when parking. Slowly approaching an object behind or, with the appropriate PDC equipment, also in front of your vehicle is signaled by:

General information

Measurements are made by ultrasound sensors in the bumpers.

The range, depending on the obstacle and environmental conditions, is approx. 6 ft/2 m .

An acoustic warning is first given:

Display

Signal tones

When approaching an object, an intermittent tone is sounded that indicates the position of the object. For example, if an object is detected to the left rear of the vehicle, a signal tone sounds from the left rear speaker.

The shorter the distance to the object becomes, the shorter the intervals.

If the distance to a detected object is less than approx. 10 in/25 cm , a continuous tone is sounded.

With front PDC: if objects are located both in front of and behind the vehicle, an alternating continuous signal is sounded.

The signal tone is switched off:

Volume

The volume of the PDC signal tone can be adjusted similar to the tone and volume settings of the radio.

The setting is stored for the remote control currently in use.

Visual warning

The approach of the vehicle to an object can be shown on the Control Display. Objects that are farther away are displayed on the Control Display before a signal tone sounds.

A display appears as soon as Park Distance Control (PDC) is activated.

The range of the sensors is represented in the colors red, green and yellow.

When the image of the rearview camera is displayed, the switch can be made to PDC:

System limits

Limits of ultrasonic measurement

The detection of objects can reach the physical limits of ultrasonic measurement, e.g., in the following circumstances:

Low objects already displayed, e.g., curbs, can move into the blind area of the sensors before or after a continuous tone sounds.

False warnings

PDC may issue a warning under the following conditions even though there is no obstacle within the detection range:

A Check Control message is displayed.

The range of the sensors is shown as a shaded area on the Control Display.

More than one assistance function can be active at the same time.

Pathway lines

  • Can be shown in the rearview camera image when in selector lever position R.

  • Help you to estimate the space required when parking and maneuvering on level roads.

  • Are dependent on the current steering angle and are continuously adjusted to the steering wheel movements.

Turning circle lines

  • Can be shown in the rearview camera image.

  • Show the course of the smallest possible turning circle on a level road.

  • Only one turning circle line is displayed after the steering wheel is turned past a certain angle.

Obstacle marking

General information

Marks for detected obstacles can be shown in the rearview camera image.

Their colored steps match the markings of the PDC. This simplifies estimation of the distance to the object shown.

Parking using pathway and turning circle lines

  1. 1.

    Position the vehicle so that the turning circle lines lead to within the limits of the parking space.

  2. 2.

    Turn the steering wheel to the point where the pathway line covers the corresponding turning circle line.

Detection of objects

Very low obstacles as well as high, protruding objects such as ledges may not be detected by the system.

Assistance functions also take into account data of the PDC.

Follow instructions in the PDC chapter.

The objects displayed in the Control Display under certain circumstances are closer than they appear. Therefore, do not estimate the distance from the objects on the display.

Side View

The concept

Side View

Side View provides an early look at cross traffic at blind driveways and intersections. Road users concealed by obstacles to the left and right of the vehicle can only be detected relatively late from the driver's seat. To improve visibility, two cameras in the front of the vehicle record the traffic situation on each side.

Notes

The images from both cameras are shown simultaneously on the Control Display.

The concept

Parking assistant

This system assists the driver in parking parallel to the road.

Ultrasound sensors measure parking spaces on both sides of the vehicle.

The parking assistant calculates the best possible parking line and takes control of steering during the parking procedure.

When parking, also take note of the visual and acoustic information and instructions issued by the PDC, the parking assistant and the rearview camera and react accordingly.

A component of the parking assistant is the PDC Park Distance Control.

Hints

An engine that has been switched off by the Auto Start Stop function is restarted automatically when the parking assistant is activated.
