Your authorized Audi dealer has a variety of
dedic ated veh icle-car e 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 caut ion 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 polish remover or other volatile
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ign it ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. w ithout pro
tecting your hands and arms. You may c u t yourself on sharp -edged metal parts .
Cleaning and protec tion 189
- Moisture and ice on brakes may impair
brak ing effic iency¢
page 178. Test the
brakes carefully each time you wash the
veh icle.
@) For the sake of the environment
Select on ly environmentally friend ly clean
i ng products . Leftover cleaning products
should not d isposed of in the household
waste.
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n
fluences is
frequent washing and waxing . How
often t his is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasonal and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle
body, the more lasting their destructive ef
fects wi ll be . High temperatures caused by ex
posure to intense sun light intens ify the corro
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .

Windows
Clear vision to all sides.
Clean all windows regularly to remove road
film and car wash wax buildup.
• Remove snow from windows using a brush.
• Use a plastic ice scraper to remove ice from
windows and mirrors.
• Remove other residue on the windows with
a spray-on glass cleaner .
• Wipe the windows dry w ith a clean p iece of
cloth or kitchen paper towel.
The best way to remove snow from windows
and mirrors is to use a brush. Use a non -abra
sive
p la stic ic e scrap er -better still, a spray
de icer - to remove
ic e from windows and mir
r ors.
T he windows must not be cleaned with insect
remover or wax s ince these can interfere with
the function of the w indshield wiper blades
(chatter).
O il, grease, or silicone residue can be removed
w ith
glass cleaner or silicon e re mover. H ow
ever, wax residue requ ires the use of a special
l y form ulated solvent. P lease contact your au
thor ized Audi dealer for adv ice on safe prod
ucts for wax removal.
W indows shou ld a lso be cleaned on the inside
at regular i nterva ls.
Never dry w indows with the same chamois
that you use to dry painted surfaces . Wax resi
due on the chamois can impair vision through
the windows.
.8, WARNING
- Alw ays re ad and heed all WARN INGS and
other information
~ page 189.
- The windshie ld m ust not be treated with
water-repe llent m aterials. They can i n
crease glare under poor visib ility condi
tions such as wetness, darkness, or whe n
the sun is low on the horizon . In addi
t ion, they can cause the windshield wip
ers to chatter.
Cleaning and protec tion
@ Note
- Never use warm or hot water to remove
snow and ice from w indows and mirrors .
Th is could cause the glass to crack.
- To prevent damage to the wires of the
rear defogger, do not place any adhesive
st ickers on the ins ide of the rear w indow
over the wires.
- To help prevent dirt from scratching the window, always scrape in a forward di
rection - pushing the scraper away from
you - never back and forth.
- Water leak ing from the inside of the rear
w indows may damage sens itive electrical
compone nts located either under the
rear parcel shelf or in the rear trunk area.
Always ensure tha t water never lea ks
t hro ugh the body section of the vehicle.
Yo u can do th is by using waterproof pro
tection over the vehicle's electrical com
ponents (e.g . when install ing window
tinting) .
- Damage or malfunction of electrical
components due to water damage or any
other o utside infl uence is not covered by

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-impo rtant 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 mo re 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.
Avoiding damage I f 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 ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires 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 whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on r ims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one s ide, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar
rows on the s id ewa ll, that po int in the direc
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.
For more information
¢ page 250.
A WARNING
-New tires or tires that are o ld, worn or
damaged cannot provide maximum con
trol and braking ability .
-
-New tires tend to be slippery and must
also be broken-in. To reduce t he risk of
losing control, a collision and se rious
pe rsonal injuries, drive w it h specia l care
for the first 350 miles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail
ure, including a blowou t and sudden de
fl ation, c rashes and seriou s personal in
juries . Have wo rn or damaged t ires re
p laced immediate ly .
- T ires age even if they are not being used
an d 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
yo u 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.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al
ways stop as soon as it is safe to do so
and check the wheels and tires for dam
age .
