the vehicle is at a standstill and a front
door is opened.
iWhen intermittent wiping is on and the
key is turned from position1 to
position2 in the steering lock
(page 33), and kept in that position
for longer than two seconds, the wipe
interval will be set to approximately
five seconds.

off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
