Care of exterior
Washing
F requent washing protects the vehicle.
The best protection against environmental influences is frequent
washing a nd waxing.
How often this is required depends on :
• How much the vehicle is used
• Where the vehicle is parked (garage, in the open under trees ,
etc.)
• The seasonal and weather conditions
• Environmenta l influences
The longer bird droppings, insects, tree resin, road and industrial
gri me, tar, soot, road salt and other materials remain on the vehicle
body , the more lasting their destructive effects will be. .,_

The best way to remove snow from windows and mirrors is to use a
brush . Use a non -abrasive
pla stic ice scraper -better still, a spray
deicer -to remove
ice from w indows and mirrors .
The windows must not be cleaned with insect remover or wax since
these can inter fere with the function of the w inds hie ld w iper blades
(chatter).
Oil, grease o r sil icone residue can be removed with
glass cleaner or
s ilicone remover . However, wax residue requires the use of a
spec ially fo rmulated so lvent . Please contac t your authorized Audi
dea ler for advice on safe products for wax removal.
Windows should also be c leaned on the inside at regular interva ls .
Never dry windows with the same chamois that you use to dry
painted surfaces . Wax residue on the chamois can impair vision
t hrough the windows .

• The windshield mu st not be treated with water -repellent mate ­
rials. T hey c an incre ase gl are under poor v isibility conditions such
a s wetne ss, darkne ss, or when the sun i s low on the hori zon. In
addition , they can cause the wind shield wipers to chatter .

~ page 206.
0 Note
• Never use warm or hot water to remove snow and ice from
windows a nd mirrors . This cou ld cause the glass to crack.
• T o prevent damage to the wires of the rear defogger, do not p lace
any adhesive stickers on the inside of the rear window over the
wires .
• T o he lp prevent dirt from scratching the window, always scrape
in a forward direction -pushing the scraper away from you -never
back and forth. •

Be sure to reach and treat all parts of the rim.
To preserve the decorative appearance of the cast alloy wheels,
some special care is necessary. In addition to road dirt and salt, brake dust is also corrosive . If left on for too long, brake dust can
cause pitting.
Use on ly specia l acid -free cleaners formu lated for a lloy rims . Safe

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of
oil.
The engine in your Audi is a sophisticated powerplant that was built
to exacting specifications . This engine needs the right kind of
engine oil that meets specifications regarding quality and viscosity
so that it can run smoothly and reliably. Choosing the right oil and
changing oil within the time and mileage intervals printed in your
vehicle's Warranty
& Maintenance booklet matters a lot more today
than it did years ago. Audi has developed a special quality standard
for engine oil that will help assure that your vehicle's engine will get
the lubrication it needs for proper operation .
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine
lubrication that can outlast traditional petroleum-based oils,
making them a smart choice for use throughout the life of your Audi .
Whether you use synthetic or petroleum-based engine oil, the oil
that you use must conform to Audi's oil quality standard VW 502 00
