GF54.65-P-3000TX Driving, Function
- with CODE (220) Parktronic system (PTS)

Component Identification:

Function requirements:
^ Circuit 15 ON
^ Parking brake not actuated

General
When the ignition is switched on (circuit 15 ON), the PTS control unit performs a self-test. If there are no malfunctions or faults, this is indicated by the lighting of the standby bar in the middle of the warning indicators
The PTS OFF switch in the lower control panel control unit can be used to switch the Parktronic system (PTS) on and off manually. When the Parktronic system (PTS) is off, the function LED in the PTS OFF switch is lit; conversely the LED is off when the Parktronic system (PTS) is activated.
When the ignition is switched on (circuit 15 ON) the Parktronic system (PTS) is automatically activated, even if it was deactivated in the previous ignition sequence.

The brightness of the warning indicators is automatically adjusted to suit the ambient light conditions. When the rain/light sensor reports "night", the warning indicators are dimmed. Conversely by "day" the warning indicators are actuated at full brightness.
In the case of an acoustic warning, the PTS control unit sends a command to the audio gateway control unit which mutes the connected audio sources.
While driving, the Parktronic system (PTS) changes to standby mode at speeds below 40 km/h down to 16 km/h, i.e. the PTS control unit, the warning indicators and the sensors are supplied with voltage but do not function.

Front monitoring range active (Selector lever position "D")
When the vehicle drops below the lower limit speed of 16 km/h, the Parktronic system (PTS) changes to measurement mode.

If obstructions are detected in front of the vehicle, the driver is alerted visually at first by the lighting of various LEDs in the center warning indicator. When the range drops below a certain distance the warning also becomes acoustic, first with an intermittent tone and then with a continuous signal (see table below). When the vehicle exceeds the upper limit speed of 18 km/h, the Parktronic system (PTS) changes back to standby mode.

Front and rear monitoring ranges active (Selector lever position "R" or "N")
When the vehicle drops below the lower limit speed of 16 km/h, the Parktronic system (PTS) changes to measurement mode. If obstructions are detected in front of or behind the vehicle, the driver is alerted visually at first by the lighting of various LEDs in the center warning indicator or the rear warning indicator. When the range drops below a certain distance, the warning also becomes acoustic, first with an intermittent tone and then with a continuous signal (see table below).
When the vehicle exceeds the upper limit speed of 18 km/h, the Parktronic system (PTS) changes back to standby mode.
