sary.
Setting sensitivity level of rain sensor
– Set control to the right: highly sensi-
tive.
– Set control to the left: less sensitive.
When the ignition is switched off and then
back on, the rain sensor stays on and starts
operating again when the windscreen wipers
are in position 1 and the vehicle is travel-
lin g at
mor

e than 4 km/h (2 mph).
Rain sensor modified behaviour
Possible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 144 of
the rain sensor include:
● Damaged blades: a film of water on the
damag
ed blades may lengthen the activation
time, reduce the washing intervals or result
in a fast and continuous wipe.
● Insects: insects on the sensor may trigger
the winds
creen wiper.
● Salt on roads: in winter, salt spread in the
roa
ds may cause an extra long wipe when the
windscreen is almost dry.
● Dirt: dry dust, wax, coating on glass (Lotus
effect) or trac
es of detergent (car wash) may
0 1
A reduce the effectiveness of the rain sensor or
m
ak
e it

react more slowly, later or not at all.
● Cracked windscreen: the impact of a stone
wil
l trigger a single wipe cycle with the rain
sensor on. Next the rain sensor detects the
reduction in the sensitive surface area and
adapts accordingly. The behaviour of the sen-
sor will vary with the size of the damage
caused by the stone. WARNING
The rain sensor may not detect enough rain
to sw it

ch on the wipers.
● If necessary, switch on the wipers manually
when water on the w
indscreen obstructs visi-
bility. Note
● Cle

an the sensitive surface of the rain sen-
sor regularly and check the blades for dam-
age ››› Fig. 144 (arrow).
● To remove wax and coatings, we recom-
mend a window c
leaner containing alcohol. 139
