Driver assistance systems
Parking sensor system*
Introduction
The parking sensor system assists the driver when parking. If the rear of the
vehicle is approaching an obstacle, an intermittent audible warning is emit-
ted. The shorter the distance, the shorter the intervals between tones. If the
vehicle is too close to the obstacle, the audible warning becomes constant.
If you continue to approach an obstacle when the sound is continuous, this
means the system can no longer measure the distance.
Sensors situated on the rear bumper transmit and receive ultrasound. Using
the ultrasound signal (transmission, reflection from the obstacles and re-
ception), this system continuously calculates the distance between the
bumper and the obstacle.
WARNING
The parking distance warning system cannot replace the driver's assess-
ment of the situation.
● The sensors have blind spots in which obstacles and people are not
registered.
● Always observe the area around the vehicle, as the sensors do not al-
ways detect small children, animals or objects.
WARNING (Continued)
● The surface of certain objects and some clothing do not reflect the ul-
trasound signals from the parking distance system. The system cannot
detect or incorrectly detects these objects and people wearing these
types of clothes.
● External sound sources can affect the parking distance aid signals. In
this case, under certain circumstances, people and objects will not be de-
tected.
CAUTION
● The sensors may not always be able to detect objects such as trailer
draw bars, thin rails, fences, posts, trees and open luggage compartments,
etc. This could result in damage to your car.
● Although the parking sensor system detects and warns of the presence
of an obstacle, the obstacle could disappear from the angle of measure-
ment of the sensors if it is too high or low and the system would no longer
indicate it. Therefore, it will not warn you of these objects. Ignoring the
warnings of the parking sensor system could cause considerable damage to
the vehicle.
● The bumper sensors may become damaged or misaligned, for example,
when parking.
● To ensure that the system works properly, the bumper sensors must be
kept clean, free of ice and snow and uncovered.
● When cleaning the sensors with high-pressure or steam cleaning equip-
ment, spray the sensors briefly at a distance of no less than 10 cm.
● Different sources of noise can produce errors in the parking distance
warning system, for example parking distance warning systems from other
vehicles, inductive loops or construction works machinery.
● Retrofitting components to the vehicle, such as a bicycle carrier, may in-
terfere with the function of the parking distance warning system.
