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.
!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 op-
erate the windshield wipers in dry 
weather conditions, always operate the 
windshield wipers with windshield 
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 result.
