the vehicle paintwork. Tailor the frequency and
extent of your vehicle care to these influences.
Corrosive substances such as spilled fuel, oil,
grease or bird droppings, must be removed im‐
mediately to prevent the finish from being altered
or discolored.
Matte paintwork
Only use cleaning and care products suitable for
vehicles with matte paintwork.
Leather care
Remove dust from the leather regularly, using a
cloth or vacuum cleaner.
Otherwise, particles of dust and road grime chafe
in pores and folds, and lead to heavy wear and
premature degradation of the leather surface.
To guard against discoloration, such as from
clothing, clean leather and provide leather care
roughly every two months.
Clean light-colored leather more frequently be‐
cause contamination on such surfaces is sub‐
stantially more visible.
Use leather care products; otherwise, dirt and
grease will gradually break down the protective
coating of the leather surface.
Upholstery material care
General information
Vacuum the upholstery regularly with a vacuum
cleaner.
If upholstery is very contaminated, for instance
with beverage stains, use a soft sponge or micro‐
fiber cloth with a suitable interior cleaner.
Clean the upholstery down to the seams using
large sweeping motions. Avoid rubbing the ma‐
terial vigorously.

Safety information
NOTICE
Open hook and loop fasteners on articles of
clothing can damage the seat covers and other
cloth upholstery in the vehicle. There is a risk of
damage to property, among other potential
damage. Ensure that any Velcro® fasteners are
closed.
Caring for special components
Light-alloy wheels
When cleaning the vehicle, use only neutral rim
cleaners having a pH value from 5 to 9. Do not
use abrasive cleaning agents or steam cleaners
above 140 ℉/60 ℃. Follow the manufacturer's
instructions.
Aggressive, acidic or alkaline cleaning agents can
destroy the protective coating of adjacent com‐
ponents, such as the brake disc.
After cleaning, apply the brakes shortly to dry
them. The heat generated during braking dries
brake discs and brake pads and protects them
against corrosion.
Chrome surfaces
Carefully clean Chrome surfaces, especially in
case of exposure to road salt, with plenty of wa‐
ter and added auto shampoo as needed.
Rubber components
Environmental influences can cause surface con‐
tamination of rubber parts and a loss of gloss.
Use only water and suitable cleaning agents for
cleaning.
Treat especially worn rubber parts with rubber
care products at regular intervals. When cleaning
rubber seals, do not use any silicon-containing
vehicle care products in order to avoid damage
or noises.
