WIPER AND WASHER SYSTEM

Front Wiper System

1. Intermittent interval adjustment function (Models without Rain Sensing Function)

   
   

   • By setting the wiper control switch (windshield wiper switch assembly) to the intermittent position, the interval time can be adjusted between approximately 1.6 seconds and 10.7 seconds using the interval time adjuster.

   

2. Washer-linked Wiper Function (Models without Rain Sensing Function)

   
   

   • When the washer switch (windshield wiper switch assembly) is operated for 0.5 seconds or more, washer fluid is sprayed and the front wipers operate in LO. When the washer switch (windshield wiper switch assembly) is operated for 1.5 seconds or more, the front wipers operate in LO for 2.2 seconds and stops after the washer switch (windshield wiper switch assembly) is turned off.

   

3. Rain Sensing Function (Models with Rain Sensing Function)

   
   

   • When the AUTO switch (windshield wiper switch assembly) is on, the rain sensor mounted on the upper area of the windshield detects the amount of rain and the luminance of the surrounding area. When the rain sensor detects rain, it sends an optimal wiper timing signal to the wiper ECU (windshield wiper relay assembly) in accordance with the vehicle speed, luminance of the surrounding area and the amount of rain detected.

   • The wiper ECU (windshield wiper relay assembly) changes the operation of the windshield wiper motor assembly as shown in the following table, based on wiper operation request signals sent from the rain sensor. If a wiper HI operation request signal is received due to a sudden increase of the amount of rain, such as a splash on the windshield, the wipers are operated continuously on HI.

   • The rain sensor detects the luminance of the surrounding area. If the luminance changes such as when the vehicle goes in or out of a tunnel, the rain sensor sends a wiper operation request signal in accordance with the situation, enabling the wipers to operate at a comfortable setting.

   Wiper Operation

   Amount of Rain	While Being Driven	While Stopped
   Large	Continuously (at HI)	Continuously (at LO)
   ↓↑	Continuously (at LO)	Continuously (at LO)
   ↓↑	Intermittently at Approximately 0.6 Seconds Interval	Intermittently at Approximately 0.8 Seconds Interval
   ↓↑	Intermittently at Approximately 1.2 Seconds Interval	Intermittently at Approximately 1.6 Seconds Interval
   ↓↑	Intermittently at Approximately 2.1 Seconds Interval	Intermittently at Approximately 3.1 Seconds Interval
   ↓↑	Intermittently at Approximately 3.5 Seconds Interval	Intermittently at Approximately 5.4 Seconds Interval
   ↓↑	Intermittently at Approximately 5.9 Seconds Interval	Intermittently at Approximately 9.7 Seconds Interval
   ↓↑	Intermittently at Approximately 10.1 Seconds Interval	Intermittently at Approximately 17.5 Seconds Interval
   Small	Intermittently at Approximately 17.9 Seconds Interval	Intermittently at Approximately 32.7 Seconds Interval
   No detection	Not operated	Not operated

4. Rain Sensor Sensitivity Adjustment Function (Models with Rain Sensing Function)

   
   

   • When the AUTO switch (windshield wiper switch assembly) is on, operating the sensitivity switch adjusts the sensitivity of the rain sensor to adjust the wiper operation timing.

5. Washer-linked Wiper with Drip-prevention Function (Models with Rain Sensing Function)

   
   

   • When the windshield wiper switch assembly is set to off or AUTO and the washer switch is turned on, the wipers start on LO at the same time as the washer fluid is sprayed.

   • The wipers operate 3 times on LO after the washer switch is turned off.

   • When the washer switch is turned on for approximately 0.5 seconds or more and vehicle speed is approximately 4 km/h (2 mph) or less, as shown in the following diagram, after the end of this operation, the wipers operate once more.

   

6. Vehicle Speed-Sensing, Adjustable Interval Function (Models with Rain Sensing Function)

   
   

   • When the windshield wiper control switch (windshield wiper switch assembly) is in the intermittent position, the interval time of the wiper is controlled in 3 stages in accordance with the automatic control adjuster position and the vehicle speed.

   • The interval time can be controlled steplessly within each range.

   

7. Vehicle Speed Switching Function (Models with Rain Sensing Function)

   
   

   • When the vehicle stops with the wiper control switch (windshield wiper switch assembly) in the low position, the front wiper operation changes to INT mode automatically.

   • When the wiper control switch (windshield wiper switch assembly) is changed from a position other than low to the low position, the front wiper operates 3 times in LO.

   

   
   

   • When the vehicle stops moving and the windshield wiper switch assembly is in the LO position, the wipers operate twice in LO. It then switches to intermittent operation with an interval time of approximately 2.5 seconds. If the vehicle starts moving during this intermittent wiper operation, the wiper automatically returns to LO operation.
