Switches and Controls
NOTE
Switching the auto-wiper lever from

the OFF to the AUTO position while
driving activates the windshield
wipers once, after which they
operate according to the rainfall
amount.
The auto-wiper control may not

operate when the rain sensor
temperature is about －10 °C (14 °F)
or lower, or about 85 °C (185 °F) or
higher.
If the windshield is coated with

water repellent, the rain sensor may
not be able to sense the amount of
rainfall correctly and the auto-wiper
control may not operate properly.
If dirt or foreign matter (such as ice

or matter containing salt water)
adheres to the windshield above the
rain sensor, or if the windshield is
iced, it could cause the wipers to
move automatically. However, if the
wipers cannot remove this ice, dirt or
foreign matter, the auto-wiper
control will stop operation. In this
case, set the wiper lever to the low
speed position or high speed
position for manual operation, or
remove the ice, dirt or foreign matter
by hand to restore the auto-wiper
operation.
If the auto-wiper lever is left in the

AUTO position, the wipers could
operate automatically from the effect
of strong light sources,
electromagnetic waves, or infrared
light because the rain sensor uses an
optical sensor. It is recommended
that the auto-wiper lever be
switched to the OFF position other
than when driving the vehicle under
rainy conditions.
