Turn the knob up or down as far as it will go, to squirt washer fluid on the rear window. The knob automatically returns from these positions after it is released.

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 you can wash the windshield but not the rear window, check the fluid level.

Caution: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision.
