This knob is located on the instrument panel below the climate controls.

(Rear Wiper): Turn the knob to 1 for a slower wiping speed or to 2 for a faster wiping speed.

0 (Off): Turn the knob to 0 for off.

(Washer Fluid): To wash and wipe the window, press the button within the knob with this symbol. The rear window washer uses the same fluid bottle as the windshield washer. However, the rear window washer will run out of fluid before the windshield washer. If the windshield can be washed, but not the rear windows, check the fluid level.
