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

ment .
.,. 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)
I. (Canadian models)
will come on
q page 18 . Do not continue to oper­
ate the vehicle . The complete brake system
shou ld be thorough ly checked by an authorized
Audi dealer or other qualified fac ility and the
cause corrected .
If the brake fl uid level is too
l ow, the bra ke war ning/ indicato r light w ill illumi­
na te. Cont act an a uthor ized Audi dealer

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
Audi
dealer .
Your dealer has the correct tools, the

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

touch up/down func-power window molfunc-
tion tions

The "GVWR" includes the weight
of the basic vehicle, all factory in­stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle . If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­ sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
Tires and wheels
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the driver's side B-pillar
¢ page 263,
fig. 204.
A WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to
carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to- tal load being transported -,..
