Replacing the rear wiper blade
Your rear wiper blade's service life is affected by the water, dirt and debris that it sweeps off your rear windscreen. The wiper blade needs to be replaced when it shows signs of wear.
Make sure you have the off wiper mode selected. You can do this by rotating the scroll wheel on the end of the left-hand steering wheel stalk.
Activate the rear wiper service position via the centre display.
Hold the centre of the wiper arm and lift it up and away from the rear windscreen.
Press the indents on both sides of the wiper arm as you pull the blade straight out, parallel with the wiper arm.
Pinch the clips at the end of the new blade and fit them into the wiper arm. Slide the blade in until it clicks into place.
Check that the blade is firmly attached to the wiper arm.
Fold the wiper arm back down against the rear windscreen.
