CAUTION
Do not shade the rain sensor by
   
adhering a sticker or a label on the
windscreen. Otherwise the rain
sensor will not operate correctly.
When the wiper lever is in the
    
position and the ignition is switched
ON, the wipers may move
automatically in the following cases:
If the windscreen above the rain
      
sensor is touched or wiped with a
cloth.
If the windscreen is struck with a
      
hand or other object from either
outside or inside the vehicle.
Keep hands and scrapers clear of the
 
windscreen when the wiper lever is
in the position and the ignition
is switched ON as fi ngers could be
pinched or the wipers and wiper
blades damaged when the wipers
activate automatically.
If you are going to clean the

windscreen, be sure the wipers are
turned off completely (when it is
most likely that the engine is left
running) this is particularly important
when clearing ice and snow.
Switches and Controls
NOTE
Switching the auto-wiper lever from
   
the to the
driving activates the windscreen
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 windscreen is coated with
   
water repellent, the rain sensor may
not be able to sense the amount of
rainfall correctly and auto-wiper
control may not operate properly.
If dirt or foreign matter (Such as
   
ice or matter containing salt water)
adheres to the windscreen above
the rain sensor or if the windscreen
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
   
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 position other than when
driving the vehicle under rainy
conditions.
