Lights and visibility
To ensure the headlight washers work cor-
r
ectly in wint
er
, any snow which has got into
the bumper jet supports should be cleaned
away. If necessary, remove snow with an an-
ti-icing spray.
Note
The wiper will try to wipe away any obsta-
cles that are on the windscr
een. The wiper
will stop moving if the obstacle blocks its
path. Remove the obstacle and switch the
wiper back on again.

Fig. 157 of the
rain sensor include:
●
Damaged wipers: a film of water on the
damaged blades may lengthen the activa-
tion time, reduce the washing intervals or re-
sult in a fast and continuous wipe.
●
Insects: insects on the sensor may trigger
the windscreen wiper.
●
Salt on the road: in winter, salt spread on
the roads may cause an extra long wipe
when the windscreen is almost dry.
●
Dirt: dry dust, wax, coating on glass (Lotus
effect) or traces of detergent (car wash) may
reduce the effectiveness of the rain sensor or
make it react more slowly, later or not at all.
●
Windscreen crack: the impact of a stone
will trigger a single wipe cycle with the rain
sensor on. Next the rain sensor detects the re-
duction in the sensitive surface area and
adapts accordingly. The behaviour of the
sensor will vary with the size of the damage
caused by the stone.
WARNING
The rain sensor may not detect enough rain
to swit
ch on the wipers.
●
If necessary, switch on the wipers man-
ually when water on the windscreen ob-
structs visibility.
