blade or the wiper motor.
• Do not use the wipers to clear a frosted window . Using the
wipers as a convenient ice scraper will destroy the wiper blades .
• Before you take your vehicle to an automatic car wash , make sure
you have the windshield w iper system switched off (lever in position
0), otherwise the windshield wiper system could get damaged in the
car wash if it should suddenly come on .
[ i J Tips
• The rain sensor is part of the interva l wiping system . Turning off
the ignition will also deactivate the rain sensor. To reactivate the sensor, switch off the interval wiping function, then switch it back
on again. •
If you switch off the ignition with the windshield wiper lever sti ll
in the interva l wipe position and then come back a while later and
drive off, the rain sensor will reactivate itself after the vehicle speed
has exceeded 4 mph (6 km/h) .
• Worn or dirty windshield wiper b lades cause smearing which
can affect the opera tion of the rain sensor . Check the conditio n of
your windshield wiper blades regularly .
• Make sure the washer fluid reservoir in the engine compartment
is topped off before going on a long trip . Look
up=> page 291 for
checking and filling the washer container .•
