Care and cleaning
Care and cleaning
General information
Regular, proper care he lps to maintain your vehi ­
cle's value.
It can also be a requirement when
submitting warranty claims for corrosion damage
and paint defects on the body.
The necessary care products can be obtained
from your authorized Audi dealer . Read and fol­
low the instructions for use on the packaging.
A WARNING
-Using cleaning and care products incorrectly
can be dangerous to your health.
- Always store cleaning and care products out of reach of children to reduce the risk of poi­
soning .
@ For the sake of the environment
-Preferably use environmentally-friendly
products when buying cleaning agents.
- Do not dispose of leftover cleaning and care
products with household trash .
Car washes
The longer that deposits remain on the vehicle,
the more the surface may be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, rinse
off heavy deposits with
p lenty of water.
Stubborn deposits such as bird dropp ings or tree
sap are best removed with plenty of water and a
microfiber cloth .
A ls o, wash the underside of your veh icle once
road salt stops be ing used for the season .
Pressure washers
When washing your veh icles with a pressure
washer, always follow the operating instructions provided with the pressure washer. This is espe­
cially important in regard to the p ressure and
spray ing distance. Do not direct the stream of
water directly onto sea ls for the side windows,
doors, luggage compartment lid or hood or onto
184
the tires , rubber hoses, insulat ing material, the
power top, sensors* or camera lenses *. Keep a
distance of at least 16 inches (40 cm) .
Do not remove snow and ice with a pressure
washer.
Never use rotary nozzles or high pressure noz­
zles.
The water temperature must not be above 140 °F
(60 °().
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and power top are
closed and the windshield wipers are off. Follow
instructions from the car wash operator, especial­
ly if there are accessories attached to your vehi­
cle.
If possible, use car washes that do not have
brushes .
Washing by hand
Clean the veh icle starting from the top and work­
ing down using a soft sponge or cleaning brush.
Use solvent -free cleaning products.
Washing vehicles with matte finish paint by
hand
To avoid damaging the paint when washing, first
remove dust and large particles from your vehi ­
c le. Insects, grease spots and fingerprints are
best removed with a specia l cleaner for matte
finish paint.
Apply the product using a microfiber cloth . To
avoid damaging the paint surface, do not use too much pressure.
Rinse the vehicle thoroughly with water. Then
clean using a neutral shampoo and a soft micro­
fiber cloth .
Rinse the vehicle thoroughly again and le t it air
dry. Remove any water residue using a sham my.
A WARNING
- Only wash the vehicle when the ignition is
off and follow the instructions from the car

Wheels and Tires
General information
.,.Che ck your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protec t your tires from oil,
grease and fuel.
.,.Ma rk tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
.,.Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold tem­
peratures, cracks can form on
the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.

Uniform Tire Quality Grading
is a tire information system devel­

to help buyers make relative com­
parisons among tires . The UTQG is
not a safety rating and not a guar­
antee tha t a tire will last for a
prescribed number of miles (ki lo­
meters) or perform in a certain
way. It simply gives tire buyers
additional information to com­
bine with othe r considerations,
s u ch as price , brand loyalty and
dealer recommendations . Under
UT QG,
tir es a re grade d by the tire
manu factu rers in three areas :
treadwear, traction, and tempera­
ture resistance. The UTQG infor­ mation on the tires, mo lded into
the sidewalls .
U.S. DOT Tire Identification
Number (TIN)
This is the tire's "serial number" .

des that may or may not be used

formation is used to contact con­
sumers if a tire defect requ ires a
recall.

tire that is determined by d istrib­
uting to each ax le its share of the
curb weight , accessory weight,
and norma l occupant weigh t (dis­
tributed in acco rdance with
