If the windscreen wipers begin to move while you are changing the wiper blades, you can be trapped by the wiper arm.
If the wiper arm on the windscreen or rear window is folded back before a wiper blade has been fitted, the window may be damaged by the force of the impact.
If the windscreen wipers have been folded back from the windscreen when the bonnet is opened, the windscreen wipers or the bonnet may be damaged.
If the colour of the maintenance display changes from black to yellow, the wiper blades should be replaced.
The time until the colour changes varies depending on the usage conditions.
