1 (Low Speed): For slow, steady wiping cycles.

If the windshield wipers are in use for about six seconds
while you are driving, the exterior lamps come on
automatically if the exterior lamp control is in AUTO.
See Wiper Activated Headlamps on page 3-17 for more
information.
Clear snow and ice from the wiper blades before
using them. If the blades are frozen to the windshield,
gently loosen or thaw them. If they become damaged,
install new blades. For more information, see Windshield
Wiper Blade Replacement on page 5-59.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.

Rainsense™ Wipers
Vehicles with Rainsense windshield wipers, have a
moisture sensor for this feature mounted on the interior
side of the windshield behind the rearview mirror.
This sensor automatically operates 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 occur more
frequently. 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 system is activated.
The wiper control should be left in the off position,
unless the wiper is needed.
The Rainsense system is sensitive to vibration and can
activate if something hits the windshield or if the
vehicle hits a bump.
