not be avoided, do so only ofter doing the fol­
lowing:
When parking:
.. Apply the foot brake .
.,. Have someone place chocks under both the
vehicle and the trailer wheels .
.,. With chocks in place, slowly release the
brakes until the whee l chocks absorb the
load .
.. Turn the wheels towa rds the curb .
.. Apply the parking brake .

206 Cleaning and protection
Cleaning and protect ion
General information
Regular care preserves vehicle value.
Any automobile is exposed to industrial
fumes, corrosive road salt, etc. A well cared
for Audi can look like new many years after
purchase . Regular and correct care w ill con­
tr ibute to maintaining the beauty and value of
your Aud i.
Furthermore, good care may be a condition
for substantiating a warranty claim should
corrosion damage or paint defects occur.
Your author ized Audi dealer has a variety of
dedicated vehicle-care products and can ad­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle .
Whether you use products recommended by
Aud i or other commercially available clean ing
agents, please make sure you apply them cor­
rectly .
A WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caution labels.
- Always read directions on the container
before using any product. Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted.
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail pol ish remover or other volatile
fluids. They may be toxic, flammab le or
hazardous in other ways. Do not wash,
wax or dry the vehicle with the ignit ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, etc. without pro­
tecting your hands and arms. You may cut yourself on sharp-edged metal parts. -
Moisture and ice on brakes may impair
brak ing eff ic iency
c::> page 192 , General
information.
Test the brakes carefully
each time you wash the vehicle.
@ For the sake of the environment
Select on ly environ mentally friendly clean­
i ng products. Leftover cleaning products
should not disposed of in the household
waste.
Care of exterior
Washing
Frequent washing protects the vehicle.
The best p rotection against environmental in­
fluences is
frequent washing and waxing. How
often this is required depends on:
- How much the veh icle is used
- Where the vehicle is parked (garage, in the
open under trees, etc.)
- The seasona l and weather conditions
- Environmental influences
T he longer b ird droppings, insects, tree resin,
road and industria l gr ime, tar, soot, road salt
and other materials remain on the vehicle
body, the more lasting their destructive ef­
fects will be . High temperatures caused by ex­
posure to intense sunlight intensify the corro­
sive effect, particularly when humidity is high as well.
Under certain circumstances,
weekly washing
may be necessary. Under other conditions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferably in a
professional car wash.
A WARNING
-Always read and heed all WARNINGS and
other information
c::> page 206.

Automatic car wash
The vehicl e can b e washed in almost any
modern automatic car wash .
The vehicle paint is so durable that t he vehicle
can n ormally be washed without p roblems in
a n automatic car wash . H owever, the effect on
the paint depends to a large extent on the de­
sig n of the fac ility, the filte ring of the wash
water, the type of wash and care mater ial , etc.
If the pa int h as a dull appearance afte r go ing
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a ca r wash, be s ure to
take the usual precautions such as clos ing the
windows and power roof. Factor y installed an­
tennas m ust not be removed.
If yo u have installed additional accessor ies on
the vehicle -such as spoilers, roof rack, etc. -
it is best to ask the car was h operator if these
should be removed .
When driv ing through an automatic ca r wash,
firs t se lect the
N posit ion and then sw itch the
engine off. If you switch the eng ine off when
N is engaged, the transmission remains in N
for approximate ly 30 m inutes and then Pis
engaged.

Good anti-corrosion treatment is very impor­
tant, particularly in the winter . If the vehicle
is freq uent ly driven on salt treated roads, the
entire engine compartment and plenum panel
should be thoroughly cleaned at t he end of
winter and retreated to prevent salt damage.
At the same time, the underside of the veh icle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solut ions
1>, or if
you have the engine washed, the anti-corro­
sion treatment is a lmost always removed as
well.
It is therefore essential to have a long­
l as ting co rrosion protection reapp lied to all
surfaces, seams, joints and components in the
engine compartment.
~ WARNING
Be aware: The engine compartment of any
motor vehicle is a potentially hazardous
area.
- Before working in the engine compart­
ment, be s ure to read the informat ion

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle. Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara ­
tive ly small patch of rubber on each tire that
assures that a ll-important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry more weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separat ion and blowouts.
A voidin g damage
If you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem icals includ ing grease, oil,
gasoline and b rake fluid off the tires.
Inspect the tires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
St oring tire s
Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the wheels or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical position if they are not mounted on rims, in a horizontal pos it ion if
they are mounted on rims.
N ew tire s
New tires have to be broken in¢&,. .
The tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pattern .
Hidden damag e
Damage to tires and r ims is often not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle pulls to one s ide, th is may ind icate
t h at one of the t ires has been damaged . T he
t ir es must be checked immed iate ly by an au­
thorized Aud i dea le r or q uali fied wor kshop.
Unidirection al t ire s
A un idirectional tire can be identified by ar­
rows on the sidewall, that po int in the direc­
t ion the t ire is designed to rotate. You must
fol low the specified direction of rotation . This
is necessary so that these tires can develop
their optimum characteristics regarding grip,
road noise, wear and hydrop laning resistance.
For more information ¢
page 267.
A WARNING
-New tires or tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a co llision and ser ious personal
in ju ries, d rive w ith special ca re for the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
flation, c rashes and serious personal in­
juries . Have worn or damaged tires re­
p laced immediate ly .
- Tires age even if they are not being used
and can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.

-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
