Care and cleaning

Care and cleaning
General information
Regular, proper care helps 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 required cleaning and care products can be
obtained from an authorized Audi dealer or au-
thorized Service Facility. Read and follow the in-
structions for use on the packaging.

ZA\ 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
— Purchase environmentally-friendly cleaning
products if possible.
— Do not dispose of cleaning and care prod-
ucts with household trash.
Car washes
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the ve-
hicle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, rinse off heavy deposits with
plenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a
microfiber cloth.
Also, wash the underside of your vehicle once
road salt stops being used for the season.
Pressure washers
When washing your vehicle with a pressure wash-
er, always follow the operating instructions pro-
vided with the pressure washer. This is especially
important in regard to the pressure and spraying
distance. Do not aim the spray directly at the
seals on the side windows, doors, lids or the sun-
roof* or at tires, rubber hoses, insulating materi-
al, 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 cone nozzles or high pressure nozzles.
The water temperature must not be above 140 °F
(60 °C).
Automatic car wash
Spray off the vehicle before washing.
Make sure that the windows and roof* are closed
and the windshield wipers are off. Make sure that
the vehicle is still able to roll during the washing
process in the car wash. Follow instructions from
the car wash operator, especially if there are ac-
cessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Washing by hand
Clean the vehicle starting from the top and work-
ing downward using a soft sponge or cleaning
brush. Use solvent-free cleaning products.
Washing vehicles with matte finish paint by
hand
To reduce the risk of damaging the paint when
washing, first remove dust and large particles
from your vehicle. Insects, grease spots, and fin-
gerprints are best removed with a special cleaner
for matte finish paint.
Apply the product using a microfiber cloth. To re-
duce the risk of 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 let it air
dry. Remove any water residue using a chamois.

Z\ WARNING
—To reduce the risk of accidents, only wash
the vehicle when the ignition is off and

Service information is made available as soon as

Driving in other
countries
Government regulations in the United States and
Canada require motor vehicles to comply with
emissions regulations and safety standards.
Therefore, vehicles that were produced for the
U.S. and Canadian markets are different from
vehicles produced for other countries.
If you plan to use your vehicle outside of the
United States or Canada, it is possible that:
— Fuel may have a significantly lower octane rat-
ing. Unsuitable fuels can cause engine damage.
— Proper maintenance and repair work may not
be possible because special service equipment,
tools, or measuring devices needed for your ve-
hicle may not be available.
— Replacement parts may not always be availa-
ble.
— Navigation systems for vehicles built for the
U.S.A. and Canada will not necessarily work in
Europe, and may not work in other countries.
() Note
Audi is not liable for damage to the vehicle re-
sulting from these country-specific differen-
ces.
Maintenance, repairs,
and technical modifi-
cations
Observe the safety precautions > page 221, Gen-
eral information and > page 264, Raising the ve-
hicle.
General information
Due to the increasing complexity of technology in
these vehicles, as well as the safety and environ-
mental standards that apply, you can only per-
form a very limited amount of repairs and modifi-
cations to the vehicle yourself.
Proof of maintenance work may be required to
submit a claim within the warranty period.
We recommend that you have your vehicle serv-
iced by an authorized Audi dealer or authorized
Audi Service Facility and that Audi Genuine Parts
and Audi Genuine Accessories are used. This
helps to ensure that your vehicle's functionality,
performance, and safety are not impaired.
Maintenance and repairs
Your vehicle was designed to help keep mainte-
nance requirements to a minimum. Some regular
maintenance is required to help ensure that your
vehicle runs in a safe, economical, and reliable
manner. Please refer to your Warranty & Mainte-
nance Booklet for more detailed information
about vehicle maintenance.
When operating the vehicle under more extreme
operating conditions, for example when outside
temperatures are very low or in very dusty envi-
ronments, certain maintenance should be per-
formed between the specified intervals.
