time the ignition is switched on . The tire pressure
monitoring system cannot be selected in the In­
fotainment system. The following are examples
of situations that could cause a malfunction:
- If the message appears at the end of the adap­
tation phase, the system cannot detect the
wheels installed on the vehicle . This may result
from one or more wheels being installed with­ out wheel sensors or with incompatible wheel
sensors .
- A wheel sensor or another component has
failed .
- Using snow chains can affect the function of
the system because of the shielding effect of
the chains .
- The tire pressure monitoring system is not
available due to a malfunction .
- Transmitters with the same frequency, such as
headphones or remote-controlled devices, may
cause a temporary system malfunction due to
the strong e lectromagnetic field .
The

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 necessary care products can be obtained
from an authorized Audi dea ler or authorized
Audi Service Facility. Read and follow the instruc ­
tions for use on the packaging.
A WARNING
-Using cleaning and care products incorrectly
can be dangerous to your health.
- Always store clean ing and care products out
of reach of children to reduce the r isk of poi­
sonin g.
@ For the sake of the environment
- Preferab ly purchase environmenta lly-friend­
l y cleaning products.
- Do not dispose of leftover cleaning and care
products with household trash.
Car washes
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the ve­
h icle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, r inse
off heavy deposits with
p lenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a microfiber cloth.
A lso, wash the underside of yo ur vehicle once
road sa lt stops being used for the season .
Pressure washers
When washing your veh icle w ith a pressure wash­
er , al ways fo llow the operating instructions pro­
vided with the press ure washer. This is especially
important in regard to the pressure and spraying
distance. Do not aim the spray directly at the
306
seals on the side windows, doors, lids or the sun­
roof* or at tires, rubber hoses, insulating materi ­
a l, sensors* or camera lenses* . Keep a distance of
at least 16 in (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use cone nozz les or high pressure nozzles.
The water temperature must not be above 140 °F
(60 °C) .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and roof* are closed
and the windshie ld wipers are
off . Follow instruc ­
tions from the car wash operator, especially if
there are accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Only use car washes where the vehicle remains
stationary and the washing equipmen t moves
around the vehicle when washing and drying. Car
washes that move the vehicle t hrough the car
wash using a chain are not recommended .
Washing by hand
Clean the vehicl e 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 ­
cle. Insects, grease spots and fingerprints are
best removed with a special cleaner for matte
finish paint .
Apply t he product using a microfiber cloth. To
avoid damaging the paint surface, do not use too
much pressure.
Rinse t he ve hicle thoroughly with wate r. Then
clean using a neutral shampoo and a soft micro ­
fiber clot h.
R inse the vehicl e thoroughly again and let it air
dry. Remove any water residue using a chamois.

" N .... 0 0 :c ' & WARNING
-Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
-To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
-After washing the vehicle, the braking effect may be delayed due to moisture on the
brake rotors or ice in the winter . This in­
creases the risk of an accident. The brakes
must be dried first with a few careful brake
applications.
@ Note
-If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
-To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
-
Care and cleaning
-To reduce the risk of damage, do not wash
the power top with a pressure washer.
-To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items.
-Matte finish painted vehicle components:
-To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
-Never use protective wax. It can destroy
the matte finish effect .
-Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved .
@ For the sake of the environment
Only wash the vehicle in facilities specially de­
signed for that purpose . This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.

Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction .
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare t ire with a tread pattern in­
tended fo r use in a specific direction, please note
the following:
- The direction of rotat ion is marked by an arrow
on the side of the tire .
- If the spare tire has to be installed in the incor­
rect direction, use the spare tire only tempora ­
rily s ince the tire will not be able to achieve its
opt imum performance character istics with re­
gard to aquaplaning, noise and wear .
- We recommend that you pay particular atten­
t ion to this fact during wet weather and that
you adjust your speed to match road condi­
tions.

installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
tiona l tire .
Notes on wheel changing
Please read the information ~ page 290 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After you change a tire:
- Check the tire pressure on the spare immedi­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lb
(120 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire ,
they should be replaced before you check the
tightening torque .
Emergency assistance
-Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover.

General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
~ Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
A WARNING -
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for safe
handling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­ ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery acid to contact eyes or
skin . Flush any contacted area with water
immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion .
- Vehicle batteries generate explosive gases .
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The voltage of the booster battery must also
have a 12-Volt rating . The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial­
ly different "Ah " rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c>page 272.
@ Note
- Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
( + ) terminals are connected.
327

Emergency situations
@ Tips
The discharged battery must be properly con­
nected to the vehicle's electrical system .
When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge. Always connect the
negat ive g round cable to the negative ground
post of the battery manager control unit.
Using the jump start
cable
Both jump start cables must be connected in the
correct order!

Starting the engine
~ Sta rt the eng ine on the vehicle providing the
jump start @and let it run at idle.
~ Now start the engine on the vehicle with the
drained battery @.
~ If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approx imately 30 seconds.
~ Remove the cables when the engi nes are run­
ning. Remove them in reverse order from the
way they were installed.
~ Close the cover on the posi tive terminal.
The battery is vented to the outside to prevent
gases from enter ing the vehicle interior. Make
sure that the jumper clamps are well connected
with their
metal ports in full contact with the
battery terminals .
A WARNING
-To avoid serious personal injury and damage
to the vehicle, heed all warnings and instruc­
tions of the jumper cable manufacturer. If in
doubt, call for road service.
-Jumper cables must be long enough so that
the vehicles do not touch.
