Cleaning and protection
General information
Regular care preserves vehicle value.
Any automobile is exposed to industrial fumes, corrosive road salt,
muddy dog feet, etc . A well cared for Audi can look like new many
years a fter purchase. Regu lar a nd correc t ca re will contribu te to
maintaining the beauty and va lue of your Audi.
Furthermore, good care may be a condition for substantiating a
warr anty claim should corrosion d amage or paint defect s occur .
Your authorized Audi dealer has a variety of dedicated vehicle- care
product s
and can adv ise whic h ones to use fo r clea ning the exterior
and interior of your vehicle.
Whether you use prod ucts recom mended by Audi or o ther commer ­
cia lly availab le cleaning agents, please make sure you app ly them
correctly.
& WARNING
• Cleaning agents may be poi sonous . Keep them out of the reach
o f children .
• Heed all cau tion label s.
• Always read directions on the container before u sing any
p rodu ct. Follo w the di re ction s carefully .
• Most chemical cleaners are concentrated and have to be
diluted.
• Use spot removing fluids only in well ventilated area s.
• Do not use gasoline , kerosene , die sel fuel , n ail polish remo ver
or other vol atile fluids . They may be toxic , flammable or ha zardous
in other way s. Do n ot wash , w ax or dry the vehicle with the igni ­

& WARNING (continued )
• Do not clean the under sides of chassis , fenders , wheel cover s,
etc . without protecting your hands and arms. You may cut yourself
on sha rp -edged metal parts .

~ For the sake of the environment
Select only enviro nmen ta lly friend ly c leaning pr oducts . Leftover
clean ing products should not disposed of in the household waste. •
Care of exterior
Washing
Frequent washing protects the vehicle.
Th e best p rotection aga inst environmental influe nces is frequent
washing and waxing . How often this is required depends on:
• Ho w much the vehic le is used
• Where the vehic le is parked (garage, in the open under trees,
etc.)
• T he seasonal and weather conditions
• E nvironmenta l influences
T he longer bird droppings, insects, tree resin, road and industrial
gri me, ta r, soot, road salt and ot her mater ials rema in on the ve hicle
body, the more lasting their destruc tive effects will be . High temper­
atu res caused by exp osu re to in tense s un ligh t inte nsify the c orro -
s ive effect, particularly when hum idity is high as well .
