Parktronic (PTS) system

PTS provides the driver with information on distance to an obstacle at a car parking.

At movement by a forward course front sensors are activated only. At movement by a backing are supervised both back, and a lobby of a zone of risk.

The system joins automatically at a key povorachivaniye in the ignition lock in situation 2 and remains active until speed of movement of the car will not exceed value in 15 km/h, - system shutdown also is made automatically.
Repeated activation of PTS occurs at decrease in speed of movement of the car below a boundary in 15 km/h.

There is a possibility of compulsory shutdown of PTS by means of established on console section of the dashboard of the switch (see. Section Governing bodies and salon equipment).

Serviceability of functioning of Parktronic system to a great extent depends on extent of pollution of the built-in in slips forward and back bumpers of ultrasonic sensors. Hindrances can bring ultrasound sources (including squeal of pneumatic brakes of lorries).

The forward zone of risk is supervised by six ultrasonic sensors which have been built in in an overlay of a front bumper (two in the middle and on two on corners, back - four sensors in a rear bumper. Range of operation of sensors makes 100 cm for the central forward sensors, 60 cm for angular forward sensors, 120 cm for the central back sensors and 80 cm for extreme back sensors. The minimum admissible distance between the sensor and an obstacle makes 15 cm for angular sensors and 20 cm for central, the sensitivity threshold further is broken. Watch purity of a surface of bumpers.

Areas of coverage of PTS (1 of 2) sensors

Areas of coverage of PTS (2 of 2) sensors

Special light indicators are provided on the dashboard (see an illustration 15.1) and in assembly of the back salonny lamp.

Indicators are divided into two sections on 6 yellow and 2 red segments in everyone, - completeness of activation of segments corresponds to distance to the next obstacle. About dangerous approach to an obstacle (activation of red segments of indicators) the driver is warned by a 3-second acoustic signal.

Design of the light PTS indicator

1 — the Left side of a zone of risk
2 — the Right side of a zone of risk

At connection of electroconducting of the trailer to the turnbuckle socket (at the corresponding complete set of the car) the system is automatically disconnected.

In case of violation of serviceability of functioning of PTS red segments of all light indicators of system are activated and the 3-second acoustic signal stands out, - check purity of surfaces of bumpers. In case of need drive away the car on Mercedes-Benz car repair shop for performance of necessary regenerative repair of system.
