Caring for vehicles with matte finish
paint
App lies to vehicles: with matte finish paint
Vehicles with ma tte finish poin t require spe­
cial core due to the characteris tic s of the
point.
Automatic car washes
You must take the necessary precautions such
as closing the windows before using an auto­
matic car wash. See the car wash attendant if
there is special equipment on your vehicle
such as a spoiler or remote control antenna
c:::> CD.
Only use car washes where the vehicle re­ mains stationary and the washing equipment
moves around the vehicle when washing and
drying .
It is not possible to use car washes
that move the vehicle through the car wash
using a chain
c:::> &,.
Only use car washes that use cloth cleaning
equipment, not brushes .
Washing with pressure washers
When washing your vehicles with a pressure
washer, always follow the operating instruc­
tions provided with the pressure washer . This
is especially important in regard to the
pres­
sure
and spraying distance. Be sure to keep
enough distance from soft materials such as rubber hoses or insulating material as well as
from the parking system sensors*, which are
located in the front or rear bumper.
Never use
rotary nozzles or high pressure
nozzles.
Washing by hand
T o avoid damaging the paint when washing,
first remove dust and large particles from
your vehicle. Insects , grease spots and finger­
prints are best removed with a
special 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. Clean
the vehicle starting at the top and working to­
ward the bottom using a
neutral shampoo
and a soft microfiber cloth. Stop frequently to
rinse the cloth thoroughly.
Clean the wheels and sill panels last. Use a
clean
sponge on these areas.
Rinse the vehicle thoroughly again and let it
air dry . If there are any water spots, they can
be removed using a
leather cloth.
Clean again with the special cleaner for matte
finish paint
if necessary .
Removing stubborn dirt
Bird droppings or tree sap
are best removed
with plenty of water and a microfiber cloth.
You should rinse off
gasoline residue immedi­
ately with plenty of water .
A WARNING
--Wash your vehicle only when the ignition
is switched off to reduce the risk of a
crash .
- To reduce the risk of cutting yourself,
protect your hands and arms from metal
parts with sharp edges when cleaning
the underbody, the inside of the wheel
housings or the wheel covers.
- If washing your vehicle during the win­
ter, moisture and ice in the brake system
can affect the vehicle's braking ability.

ution. Let belts dry thoroughly and away
from direct sunlight.
~ Do not allow inertia reel safety belts to re­
tract before they are completely d ry.
~ Check the condition of your safety belts reg­
ularly.
A WARNING
Damaged safety belts can break in a crash.
- Any thing tha t might damage you r safety
belts co uld mean that you and your pas ­
sengers wo uld not be adequately pro­
tected in an accident.
- Safety belt performance depends on cor­ rect installation . Never remove belts
from the vehicle to clean them.
- Do not use chemical cleaning agents,
bleach o r dyes . They have corrosive prop­
erties which weaken the webbing.
- When cleaning your safety belts, inspect
them for damage. If you discover dam­
age, see your authorized Audi dea ler.
- Always read and heed all WARNINGS and
the informat ion
¢page 156.
1) Use o nly the correct cleaning sol utio ns. Neve r use gas­
oline or d iese l fuel.
Cleaning and protec tion
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Corrosion p rotection
The engine compartment and transmission
have been corrosion-protected at the factory.
Good anti-corrosion treatmen t is very impor­
tant, partic ularly in the winter.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and plenum panel
shou ld be thoroughly cleaned at the end of
winter and retreated to prevent salt damage .
At the same time, the underside of the veh icle
shou ld be washed as well.
If the engine compartment is cleaned at any
time with grease remov ing solutions
1>, or if
you have the engine washed, the a nti-corro­
s ion treatment is almost always removed as
well.
It i s therefo re essentia l to have a long­
lasti ng corrosion protection reapplied to all
su rfaces, seams, joints and components in the
engine compa rtment .
A WARNING
--=
Be aware: The eng ine compartment of any

- Fuel is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a cellular telephone while re­
fueling. The electromagnetic radiation
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle while re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge static electricity before touching the fill­
er nozzle again. Static electricity can

Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
In a
sealed system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a result of overheating .

It re­
quires special charging equipment and the
knowledge to go with it. We recommend hav­
ing your battery fast charged only by a quali­
fied workshop .
A discharged battery can
freeze at tempera­
tures of only 32 °F (0 °C). Allow a frozen bat ­
tery to thaw completely before attempting to
charge it
