304 Service, maintenance
To ensure proper operation of the rain
sensor 3 the sensor area must be free from
dust, dirt and ice, which is why the
windscreen wash system must be operated
at regular intervals and the sensor area
de-iced. Vehicles with rain sensor 3 can be
identified by the sensor area near the top
of the windscreen.
Service setting for front windscreen wiper
(e.g. for changing or cleaning the front
wiper blades).
Within 4 seconds from turning off the
ignition, with the key still in the lock 3 or for
the Open&Start System 3 after switching
off the ignition and before opening the
driver’s door, move the wiper stalk down.
Release wiper stalk as soon as the wiper is
vertical.
Wiper blades on the windscreen
Activate service setting – see previous
column. Raise wiper arm, tilt wiper blade
at 90° to the wiper arm and remove to the
side.
