IINormal wiper speed
IIIFast wiper speedIntermittent wiping
Intermittent wiping interval is dependent
on wetness of windshield.
Turn the combination switch to
positionI.
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.
iIf the combination switch is pressed to the
point of resistance and released, the
corresponding turn signals will flash three times.!Do not operate the windshield wipers when
the windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/or
damage the wiper blades when wiping occurs on
a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions, al-
ways operate the windshield wipers with wind-
shield washer fluid (
page 57).
!Do not leave windshield wipers in
intermittent setting when the vehicle is taken to
an automatic car wash or during windshield
cleaning. Windshield wipers will operate in the
presence of water sprayed on the windshield,
and windshield wipers may be damaged as a re-
sult.
!If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical effects
may cause the windshield wipers to wipe in an
undesired fashion. This could then damage the
windshield wiper blades or scratch the windows.
You should therefore switch off the windshield
wipers when weather conditions are dry.
