Check ing and F illing
@ For the sake of the environment
Because of the prob lem of proper disposal of
brake fluid as we ll as the special tools re­
quired and the necessary expertise, we rec­
ommend that you have the b rake fluid
changed by your author ized Audi dealer .
Battery ( 12 V)
General information
All work on the battery requires expert knowl­
edge .
Read and follow the WARNINGS
before check­
i n g a nyth ing in the engine compartment
c::> page 188, Working in the engine compart­
ment.
The batte ry in you r Aud i does not need any main­
tena nce unde r
normal operating cond itions. A udi
re commends hav ing the e lectro lyte level check
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.
T o reprogram the func tions, proceed as follows:

meters
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
c::> page 1 21.
Some conven ien ce f unctions, such as inter ior
li ght ing o r power seats* may not wor k. T hese
convenience functions will be availab le aga in
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
e r, bu t it will a lso l ast longer.
.&_ WARNING
- W ork on the b attery requires e xper t knowl­
e d ge. Con tact an a uthor ized Audi dealer or
author ized Audi Se rvice Facility for info rma ­
tion rega rding the vehicle batte ry. There is a
-
ris k for chemical burns or e xplosions . ..,.

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 ­
so stop working when there is an ESC mal­
function.

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 .
