The speed of the front and rear wipers changes automatically with vehicle speed, if configured to do so.
The speed dependent mode can be enabled or disabled by retailer/authorized repairer.
The front wipers slow to the next lowest speed if the vehicle's speed drops below approximately 5 mph (8 km/h). The original wiper speed is resumed when the vehicle's speed increases to over approximately 5 mph (8 km/h).
The frequency of the intermittent rear wiper increases when the vehicle's speed increases.
