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!
  • Headlights/rear lights
    • Never clean the headlights/rear lights with a dry cloth or sponge.
    • Do not use cleaning agents containing alcohol. This could cause the glass to crack!
  • Wheels
    • Do not use paint polish or other abrasive agents.
    • If the protective paint coating on the wheel rim is scratched or damaged by stone chips etc., the damaged area should be touched up without delay.
  • Sensors/camera lenses
    • Never remove snow and ice from the camera lens using warm or hot water - danger of cracks appearing on the lens.
    • Never clean the camera lens with cleaning agents which are abrasive or contain alcohol – danger of scratches and cracks appearing.
  • Windows
    • Remove snow and ice from windows and exterior mirrors with a plastic scraper only. To avoid scratches, the scraper should only be pushed in one direction and not moved to and fro.
    • Never use warm or hot water to remove snow and ice from windows and mirrors. This could cause the glass to crack!
    • To avoid damaging the heating element, do not put stickers on the inner side of the rear window.
  • Ornamental trim/mouldings
    • Do not use chrome cleaning agents.
  • Paintwork
    • The vehicle must be free of dirt and dust before applying polish/wax – otherwise the paintwork may be damaged.
    • Do not polish/wax the vehicle in direct sunlight – this can damage the paint!
    • Do not attempt to polish out surface rust deposits – this can damage the paint!
    • Remove cosmetics and sun lotion immediately – otherwise the paintwork may be damaged.
  • Displays
    • Displays must not be cleaned with a dry cloth – this can scratch the display!
  • Control consoles
    • Do not let any liquid get inside the control consoles – risk of damage!
  • Seat belts
    • Do not remove the seat belts to clean them.
    • Do not use chemical cleaning agents, corrosive liquids, solvents or sharp instruments to clean the seat belts or their components – this can damage the belt webbing!
    • If you find any damage to the belt webbing, the belt fittings, the belt retractor or the buckle, have the belt in question replaced by a qualified workshop.
  • Fabrics/leatherette/Alcantara
    • Do not use leather care products, solvents, wax polish, shoe cream, stain removers, or any similar products on leatherette/Alcantara fabrics.
    • To avoid damage, stubborn stains should be removed by a qualified workshop.
    • Never use steam cleaners, brushes, hard sponges or similar utensils.
    • Do not use the seat heating* to dry the seats.
    • Sharp-edged objects on clothing, such as zip fasteners, rivets or belts, can also damage the surface of the fabric.
    • Please make sure you close any velcro fasteners, e.g. on your clothing, as these could otherwise damage the upholstery.
  • Natural leather
    • Do not use solvents, wax polish, shoe cream, stain removers, or any similar products on leather fabrics.
    • Sharp-edged objects on clothing, such as zip fasteners, rivets or belts, can also damage the surface of the fabric.
    • Never use steam cleaners, brushes, hard sponges or similar utensils.
    • Do not use the seat heating* to dry the seats.
    • Avoid exposing leather to direct sunlight for long periods, otherwise it may tend to lose some of its colour. If the car is left for a prolonged period in the bright sun, it is best to cover the leather.
Note
  • It is much easier to remove dead insects if the car has been waxed recently.
  • Regular waxing can help protect against surface rust.
1) Mild detergent: not more than two tablespoons of pH-neutral detergent to one litre of water
