Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Not running the vehicle for long periods of
time
If you do not drive your ve hicle for seve ral days or
weeks, e lec trical equipment is gradually scaled
back or switched off. This reduces energy use and
ensures the veh icle wi ll be able to start after long
periods of time

funct ions, such as interior lighting o r power seat
adjustment, may not be avai lab le under certain
c ircumstances. These convenience functions will
be available again once you switch the ignition on
and start the eng ine.
Even when electrical equipment is switched off,
the eq uipment can st ill dra in the vehicle batte ry
if the veh icle is not dr iven for long pe riods of
time . Deep drai ning results in a chemica l reaction
that destroys t he ins ide of the vehicle battery .
The vehicle battery must be charged every mon th

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob
jects from the tire tread.
.,. If driving over c urbs or similar
obstacles, drive slowly and ap
proach the curb at an angle.
.,.Have faulty tires or rims re
placed immediately.
.,.Protect your tires from oil,
grease and fuel.
.,.Mark 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 ab ility. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, result ing 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 sim ilar
substances.

Tire Pressure Monitoring
System (AS, S8)
(D General notes
A ppl ies to: AS, 58
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat
ed to the inflation pressure recommended by the
veh icle manufact urer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la
be l, you should determine the proper tire infla
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll
tale when one or more of your tires is significant
ly under-inflated . Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi
cantly under-inflated tire causes the tire to over
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop
ping ability .
Please note that the TPMS is not a substitute for
p roper tire maintenance, and it is the driver's re
sponsib ility to ma intain correc t tire p ressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPM S
mal function indicator to indicate when the sys
tem is not operat ing properly. The TPMS mal
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi
mately one mi nute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal
function exists .
When the malfunction indicator is illuminated ,
the sys tem may not be able to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears

The tire pressure indicator in the instrument

A WARNING
- If the tire pressure indicator appears in the

t ir es and their pressure .
- The driver is responsible for maintaining the
correct tire pressure. You must check the

- Under certain conditions (such as a sporty
dr iv ing style, winter cond itions or unpaved
roads), the tire pressure monitoring system
indicator may be delayed.
- Do not use run-flat tires on your vehicle. Us
ing them when not permitted can lead to
vehicle damage or accidents .

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 dealer 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 cleaning and care products out
of reach of children to reduce the risk of poi
soning.
@ For the sake of the environment
- Preferably purchase environmentally-friend ly 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 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 veh icle w ith 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
306
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 in (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 washes
Spray off the vehicle before washing.
Make sure that the windows and roof* are closed
and the windshield 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 veh icle remains
stationary and the washing equipment moves
around the vehicle when washing and drying. Car
washes that move the vehicle through the car
wash using a chain are not recommended.
Washing by hand
Clean the vehicle 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 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 let it air
dry. Remove any water residue using a chamois. ..,..
