their vertical position (important when
changing the blades, or folding up
when frost is expected):
With the control lever in position 1,
switch off the ignition when the wipers
are in the parked position.
Fold the wipers down onto the
windshield before you turn the ignition
key to position 1 or 2.<
For changing the wiper blades, refer to
page 162.
1 Interval time or rain sensor*
You can set the wipe interval to 4
stages with rotary dial 6.
In addition, the wipe interval automatically
adapts to variations in road speed.
Rain sensor:
When the rain sensor is activated, the
windshield wiper is controlled automatically,
depending on the degree of wetness
of the windshield (in both snow
and rain). You do not have to be concerned
with switching the windshield
wiper on or off or adjusting the wipe interval
between intermittent and full
wipe. Instead, you can concentrate fully
