BMW 7 Series: Introduction

Windscreen Wipers

The F01/F02 has a wiper/washer system for the windscreen as standard.

Windscreen wiping has the following functions:

  • Continuous wipe in stage 1
  • Continuous wipe in stage 2
  • Flick wipe.

The following systems are also available:

  • Headlight washer system
  • Water jet heater
  • Automatic mode using the rain/light/solar/condensation sensor.

The wiper motor for the wiper/washer system is connected via a LIN bus.

Rain/lights/solar/condensation Sensor

The rain/lights/solar/condensation sensor is the same as the rain/driving lights/solar sensor, but has been enhanced with the condensation sensor function. The functionality of the rain sensor, the driving lights sensor and the solar sensor have been retained in full. This means, for example, that the driver is still assisted by the rain sensor automatically initiating the procedure for switching on the windscreen wipers.

The automatic wiping does not relieve the customer from the responsibility of wiping the windscreen. For this reason, the customer can override the automatic wiping function at any time by moving the wiper switch on the steering column stalk up or down or pulling it towards him.

The driving lights sensor supplies the on and off signal for the automatic driving lights control function.

Under unfavorable light conditions such twilight or when driving through a tunnel, the ON signal ensures the driving lights are switched on automatically.

The solar sensor makes sure the automatic climate control system provides optimum air conditioning distribution in the vehicle.

The condensation sensor allows the integrated automatic heating/air-conditioning system to detect when condensation is forming on the windscreen in good time, even before the driver is aware of it. Countermeasures can be taken automatically at an early stage, without the need for driver intervention.
