Radiator fan
The radiator fan switches on outomotico/ly by it­
self.
An auxiliary elect ric radiator fan sw itches on and
off depend ing on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fa n
can cont inue runn ing fo r up to 10 minutes -even
with the ignition off . It ca n even switch on again
later by itself¢.&. , if
- the temperature of the engine coolant r ises due
to the heat bu ild -up from the engine in the e n­
gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight .
A WARNING
-To reduce the risk of pe rsonal injury never
touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the eng ine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coo lant reaches a
certain tempe rature and w ill cont inue to run
until the coolant temperature drops.

.,. Read the brake fluid level from the brake f luid
reservoir ¢
fig. 199, ¢ page 239, fig. 193 (ga­
soil engine) or ¢
page 240, fig. 194 (diesel en­
gine). The brake fluid level must be between
the "MIN" and "MAX" markings .
The location of the brake fl u id reservoir can be
seen in the engine compartment i llustration
q page239.
The fluid level may drop slightly after some time
due to t he automatic adjustment of the brake
pads. This is not ca use for a larm.
If t he brake fluid level falls considerably below
the "M IN" mark, the brake warning/indicator
li ght ~ (U.S. models)

l ow, the bra ke war ning/ indicato r light w ill illumi­
na te. Cont act an a uthor ized Audi dealer
immedi­
atel y.
Changing brake fluid
Have the brake fluid changed by an experienced
technician.
B rake fl uid abso rbs moistu re from the air. If the
wa ter con ten t in the brake fluid is too high, cor­
r osion in the bra ke system may res ult after ape­
riod of time. The boi ling po int of the brake fluid
will a lso decrease considerably and decrease
bra king performance.
Therefore, the bra ke fluid m ust be changed
every
two year s. Always use new brake f luid which con­
forms to Federa l Motor Vehicle Standard " FMVSS
116 DO T 4" .
The brake fluid reservoir can be diffic ult to reac h,
the refore, we recommend that you have t he
brake fluid changed by your author ized

you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of chi ldren!
- Brake failure can resu lt from old or inappro­
priate brake fluid. Observe these precau­
t ions:
- Use only brake flu id that meets SA E speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid.
The correct type of brake fluid is also indi­
cated on the brake flu id reservoir.
- The brake fluid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long.
This can ser iously affect the efficiency of
the brakes as well as your safety. This
could result in an acc ident.
(D Note
Brake fluid w ill damage the pa int of your vehi­
cle.
For the sake of the environment
Because of the prob lem of proper disposal of
brake flu id as well as the special tools re­
quired and the necessary expertise, we rec­
ommend that you have the brake fluid
changed by your author ized Audi dealer.
Battery
General information
All work on the battery requires expert knowl­
edge.
Read and foll ow t he WARNING S before check­
ing anything in the engine compartment
¢ page 236, Working in the engine comport ­
ment.
Ch eck ing and Filling
Plug -in hybrid drive* : you can find important in ­
formation about the high -vo ltage battery under
¢ page 98.
The battery in yo ur Audi does not need any ma in­
tenance under
normal operating conditions . Audi
recommends having the electrolyte level check
by an authorized Audi dealer or author ized Audi
Service Facility when there are
high outside tem­
peratures or when dr iving all day. The e lectrolyte
level should also be checked each time the bat ­
tery is charged¢
page 249.
Have the battery checked when you bring your ve­
hicle in for an inspection. It is a good idea to re­
place the battery if it is more than 5 years old.
D uring certa in types of a irbag deployments, the
battery is d isconnected from the veh icle electri­
cal system for safety reasons¢
& in Repair, core
and disposal of the airbags on page 199.
Di sco nnecting the battery te rminal s
The battery should not be disconnected. Several
vehicle functions (power windows, for example)
will be lost when the battery is disconnected. The
funct ions must be reprogrammed after connect­
ing the battery. To avoid this, the battery should
only be disconnected from the vehicle electrical
system when it is absolutely necessary.
To reprogram the functions, proceed as follows:
Function Reprogramming

Check ing and F illing
Not running th e vehicle for long p eriod s of
t im e
If you do not drive your vehicle for several days or
weeks, electrical components are gradually re­ duced or sw itched off. Th is reduces energy con­
sumpt io n and maintains the vehicle's ability to
start over a long period of time
c:::, page 164 .
Some convenience functions, such as interior
lighting or power seats* may not work . These
convenience functions will be available again
once yo u sw itch the ignition on and start the en­
gine.
Winter operation
During the winter months, it is common for the
battery capacity to decrease as the temperatures
become lowe r. This is because mo re power is
needed to sta rt the veh icle and components s uch
as the headlights and the rear window defogger
are used more frequently .
Avoid using power unnecessar ily, especially in
ci ty driving or on sho rt trips. Have yo ur author­
ized Audi dealer or authorized Audi Service Facili­
ty check the battery capacity before the start of
winter c:::, page 249. A well-charged battery will
not on ly reduce starting problems in cold weath­
er, but it will also last longer .
A WARNING
-Work on the battery requires expert knowl­
edge. Contact an authorized Audi dealer or
autho rized Aud i Service Facility for informa­
t ion regarding the vehicle battery. There is a
risk for chemical burns or explosions.
- Never open the vehicle battery. Do not t ry to
c hange the batte ry electro lyte level. Othe r­
wise explosive gas wi ll escape from the bat­
te ry and increase the risk of an explos ion .
(D Tips
If your vehicle is not driven for several weeks
in very cold temperatu res, remove the batte ry
and sto re it in a pla ce where it wi ll not freeze.
This prevents the battery from being dam­
aged and needing to be replaced.

thawed batte ry again because the battery casing
can be cracked due to ice formation and can leak
battery acid.
Battery charging (Ma ximum charging rate of
30 amp s/ 14.8 Volt )
When charging at low voltages (e.g. with a trick­
le charger ),
the battery cables do not have to be
d isconnected first. The battery caps should
not
be opened when charging a battery.
It is not necessary to remove the battery from
the lu ggage compartment, and it is also not nec­
essary to disconnect the cables.

Fast charging the battery (charg ing rat e
abov e 14.8 Volts )
For technical reasons do not use a battery charg­
er that uses voltage greater than 14.8 Volts to
charge your veh icle's battery.
A WARNING
Charg ing a battery can be dangerous .
-Always follow the operating instructions
provided by the battery charger manufactur­
er when charging your battery .
- Never charge a frozen battery.
It may ex­
plode because of gas trapped in the ice. Al­
low a frozen battery to thaw out first.
- Do not reuse batteries which were frozen.
The battery hous ing may have cracked and
weakened when the battery froze.
- Charge the battery in a well ventilated area .
Keep away from open flame or electrical
spark. Do not smoke . Hydrogen gas generat­
ed by the batte ry is explosive .
- To reduce the danger of explosion, never
