When Driving

Switches and Controls

CAUTION



  Do not shade the rain sensor by 

adhering a sticker or a label on the 

windshield. 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 windshield above the rain 

sensor is touched or wiped with a 

cloth.



  If the windshield is struck with a hand 

or other object from either outside or 

inside the vehicle.

  Keep hands and scrapers clear of the 

windshield when the wiper lever is in the 

 position and the ignition is 

switched ON as fingers could be pinched 

or the wipers and wiper blades damaged 

when the wipers activate automatically.

  If you are going to clean the windshield, 

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.

NOTE



  Switching the auto-wiper lever from the 

 to the 

 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 

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.



  The auto-wiper control functions can 

be turned off. Refer to Personalization 

Features on page 9-12.
