Rainsense™ II Wipers
For vehicles with this feature, the moisture sensor is
mounted on the interior side of the windshield behind the
rearview mirror. It is used to automatically operate the
wipers by monitoring the amount of moisture build-up
on the windshield. Wipes occur as needed to clear the
windshield depending on driving conditions and the
sensitivity setting. In light rain or snow, fewer wipes will
occur. In heavy rain or snow, wipes will occur more
frequently. The Rainsense II wipers operate in a delay
mode as well as a continuous low or high speed as
needed. If the system is left on for long periods of time,
occasional wipes may occur without any moisture on
the windshield. This is normal and indicates that the
Rainsense II system is activated.
The Rainsense II system can be activated by turning the
wiper band to one of the five sensitivity levels indicated
on the wiper stalk. The position closest to off is the lowest
sensitivity setting, level one. This setting lets more rain or
snow to collect on the windshield between wipes. Turning
the wiper band away from you to higher sensitivity levels
increases the sensitivity of the system and frequency of
wipes. The highest sensitivity setting, level five is closest
to low. A single wipe occurs each time the wiper stalk is
turned to a higher sensitivity level to indicate that the
sensitivity level has been increased.
Notice: Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.
The mist and wash cycles operate as normal and are
not affected by the Rainsense II function. The Rainsense
II system can be overridden at any time by manually
turning the wiper band to low or high speed.
When Rainsense II is active, the headlamps turn on
automatically. The headlamps will turn off again once the
wipers turn off if it is light enough outside. If it is dark,
they remain on. See Wiper Activated Headlamps
on page 3-32 for more information.
Notice: Do not place stickers or other items on
the exterior glass surface directly in front of
the moisture sensor. Doing this could cause
the moisture sensor to malfunction.
