Attention! The Parktronic system does not recognize objects located in the immediate vicinity of the rear bumper at a height below or above its level (flower beds, trailer drawbars, etc. - be careful!
PTS provides the driver with information about the distance to an obstacle when reversing the car.
The system is activated automatically when the ignition key is turned to the 2 and reverse gear («R»), - the system is also switched off automatically.
Attention! The correct functioning of the Parktronic system depends to a large extent on the degree of contamination of the ultrasonic sensors mounted in the rear bumper trim. Interference can be introduced by sources of ultrasound (including the squeal of air brakes on trucks).
Layout of PTS sensors (1) rear bumper
The risk zone is monitored by four sensors mounted in the rear bumper trim. The range of the sensors is 150 cm for central sensors, 100 cm for angle sensors. The minimum allowable distance between the sensor and an obstacle is 30 cm, then the sensitivity threshold is violated. Keep the surface of the bumpers clean.

A special indicator light for the Parktronic system is located in the upper right corner of the rear of the passenger compartment, next to the tailgate on Station Wagon models and on the upper right on the roll bar on Convertible models.
Construction of the PTS indicator light
The indicator is divided into three sections of 2 red, 2 yellow and 2 green segments - the completeness of the activation of the segments corresponds to the distance to the nearest obstacle. About a dangerous approach to an obstacle (activation of the red segments of the indicators) the driver is warned by a 3-second continuous acoustic signal.
When connecting the trailer wiring to the tow bar connector (with appropriate vehicle equipment) the system will automatically turn off.
In the event of a malfunction of the PTS, the red segments of the system indicator light are activated and a 3-second acoustic signal is emitted - check the cleanliness of the bumper surfaces. If necessary, drive the vehicle to a Mercedes-Benz Dealership to carry out the necessary refurbishment of the system.
