Clear vision is an essential safety factor.

The windscreen must not be cleaned with insect remover or wax, otherwise the windscreen wipers will not function properly (juddering).

Traces of rubber, oil, grease or silicone can be removed with a window cleaning solution or a silicone remover. Wax residue can only be removed with a special cleaner. Your Audi dealer will be able to provide you with more detailed information.

The windows should also be cleaned on the inside at regular intervals.

Use a separate cloth or chamois to dry the windows. Cloths used for waxing and polishing contain residues that will cause smears on the glass.

WARNING
Do not use water-repellent coatings on the windscreen. In bad visibility conditions such as light rain, low sun or when driving at night these coatings can cause increased dazzle, which is a serious safety hazard. Such coatings can also cause the wiper blades to judder.

Caution
Х Remove snow and ice from windows and mirrors with a plastic scraper only. To avoid scratches caused by dirt on the glass, the scraper should only be pushed in one direction and not moved to and fro.
Х The heating element for the rear window is located on the inner side of the window. To avoid damaging the heating element, do not put stickers on the inner side of the window.
Х Never use warm or hot water to remove snow and ice from windows and mirrors. This could cause the glass to crack!
