Setting sensitivity level of rain sensor

tive.

back on, the rain sensor stays on and starts
operating again when the windscreen wipers

e than 4 km/h (2 mph).
Rain sensor modified behaviour
Possible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 145 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. 145 (arrow).
● To remove wax and coatings, we recom-
mend a window c
leaner containing alcohol. Rear vision mirror
Intr oduction WARNING
The automatic anti-dazzle rear vision mirror
cont ain

s an electrolytic fluid which may leak
if the mirror is broken. This could cause irrita-
tion to the skin, eyes and respiratory organs.
● The electrolytic fluid may cause irritation to
the skin, eye
s and respiratory organs, partic-
ularly in individuals suffering from asthma or
other illnesses. Make sure that adequate
quantities of fresh air enter and leave the ve-
hicle if it is not possible to open all the doors
and windows.
● If the electrolytic fluid comes into contact
with eye
s or skin, wash the area for at least
15 minutes with plenty of water, and seek
medical advice.
● If the electrolytic fluid comes into contact
with shoes
or clothing, wash the area for at
least 15 minutes with plenty of water. Wash
shoes and clothing before wearing them
again.
● If the electrolytic fluid is swallowed, wash
your mouth with p
lenty of water for at least
15 minutes. Do not try to provoke vomiting
unless recommended by a Doctor. Seek medi-
cal advice immediately. » 137
