by an au thor ized A udi dealer or au thori ze d Audi
Serv ice Facility when there a re
high outs ide tem
peratures or when driving a ll day. The elect rolyte
level sho uld a lso be checked each time the bat
tery is charged
c::> page 200.
Have the battery checked when you bring your ve
hicle in for an inspection. It is a good idea to re
p lace the battery if it is more than 5 years old .
T he batte ry is located in the eng ine compar tment
and is practically
maintenance-free .
Disconnecting the battery terminals
The battery shou ld not be d isconnected. Severa l
veh icle functions (power w indows, for example)
w ill be lost w hen the b attery is disconne cted. The
f u nctions mus t be reprog rammed after connect
in g the battery. To avo id th is, the battery shou ld
only be disconn ecte d from the vehicle e lectrica l
system when it is abso lutely necessary.

Not running the vehicle for long period s of
time
If you do not drive your vehicle for severa l days o r
weeks, electrical components are gradually re d u ced or switched off . This reduces energy con
s u mp tion and mai ntain s the vehicle's ability to
st art over a long perio d of time

once you sw itch the ignition on and start the en
gine.
Winter operation
D ur ing the winte r mon ths, it is common for the
batte ry capac ity to decrease as the temperatures
become lower . This is because more power is
needed to start the vehicle and components such
as the headlights and the rear window defogger
a re used more freque ntly .
Avoid using power unnecessa rily, espec ia lly in
c ity dr iving o r on short t rips. Have your author
i z ed Audi dealer or author iz ed Audi Se rvice Facili
ty check the battery capacity be fore the start of
winter
c::> page 200 . A well -cha rged battery will
not only reduce sta rting prob lems in cold wea th

.&_ WARNING
- W ork on the b attery requires e xper t knowl

Checking and Filling
-Before reconnecting the battery, make sure
all electrical consumers are switched off.
Reconnect the posit ive cab le first and then
the negative cable. Never interchange the cables -th is could start a fire!
- Never charge a frozen or a thawed-out bat
tery. It could explode! If a battery has fro
zen, then it must be rep laced . A discharged
batte ry can freeze over at 32 °F (0 °C).
- Make sure the vent hose is always attached
to the opening on the side of the battery.
- Never use batteries which are damaged.
The re is the danger of an explos ion! Always

A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of
vehicle control and increase the risk of an accident. Read
and follow the important safe
ty precautions in¢
page 216,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the risk of an accident because it
can cause the tire to burst and result in loss of vehicle con
trol.
-Incorrect tire pressure in creases tire wear and has a

Tires and wheels
Tire pressure monitoring

CD General notes
Applies to: ve hicles w ith tire p ressu re monitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat
ed to the inflation pressure recommended by the
vehicle manufacturer 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
bel, you should determine the proper tire infla
tion pressure for those tires) .
As an added safety feature, your vehicle has been
equipped w ith a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell
tale when one or more of your t ires 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
proper tire maintenance, and it is the driver's re
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the level
to tr igger illum inat ion of the TPMS low tire pres
sure telltale.
Your veh icle has also been equipped w ith a TPMS
malfunct ion indicator to indicate when the sys
tem is not operat ing properly. The TPMS mal
function indicator is combined w ith the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi
mately one minute and then remain continuous ly
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal
function exists .
When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended . TPMS malfunctions
222
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the veh icle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
Appl ies to: vehicles wit h Tire Pressure Mo nito rin g System in
dica tor
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Using the ABS sensors, the tire pressure monitor
i ng system compares the tire tread c ircumfer
ence and vibration characteristics of the individu
al tires. If the pressure changes in one or more
tires , this is indicated in the instrument cluster
display with an
Ii] indicator light and a message.
If only one tire is affected, the location of that
tire will be indicated. The message turns
off after
a few minutes. You can display the message
again
,=;, page 25.
The tire pressures must be stored in the menu
display again each time the pressures change
(switching between partial and full load pres
sure) or after changing or replacing a tire on your
vehicle

ing system on ly monitors the tire pressure you
have stored . You can find the recommended tire

A WARNING
- If the tire pressure warning light IE in the
instrument cluster turns on, the pressure in
one or more tires is too low . Reduce the ve
hicle speed immediately and avo id any hard
steering or braking maneuvers. Stop as soon as possible, check the tire and inflate the
t ire to the correct pressure, which is speci
fied on the tire pressure label on the veh icle
<=:> page 214. Driving w ith a t ire with low
pressure c auses the t ire to overheat and can
result in failure of the tire . Low pressure can
also have a negative effect on the driving
and braking behavior of the vehicle .
- T he driver is responsib le for maintaining the
correct tire pressures . You must check the
tire pressures regularly .
- Under certain conditions (such as a sporty
driv ing style, winter conditions or unpaved
roads), the pressure monitor 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 .
(D Tips
-The tire pressure monitoring system can al

- The tires with the identification "AO" or

We recommend that you use these tires.
- The tire pressure monitoring system can on

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It i s becom ing increasingly more and more diffi
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re
moved before you are ab le to get to the bulb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
