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.

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
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
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
Power window one-¢ page 44, Correcting

different tire speeds. For this rea­son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires.
&_ WARNING -
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle . Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
Tires and wheels
-Only use tires that are more
than 6 years old when abso­ lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on the vehicle, make sure they al­low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage
Fig. 203 Tire profile: tread wear indica ­
tor
Tire wear
Check the tires regularly for wear .
- Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear. ..
261

Tires and wheels
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire
inflation pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
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
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating 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 minute and then remain continuously
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
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle 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
wheels allow the TPMS to continue to function
properly .

· If the Tire Pressure Monitoring System
indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 206 Instrument cl uster: i ndic ator lig ht with message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
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 indicator light
Rt] and a message
¢fig. 206. If only one tire is affected, the loca­
tion of that tire will be indicated. The message
turns off after a few minutes. You can display the
message again¢
page 30.
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
¢ page 273. The tire pressure monitor­
ing system only monitors the tire pressure you
have stored . You can find the recommended tire
pressures for your vehicle on the label on the
driver's door pillar¢
page 263.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- If the tire pressure in one or more tires is too
low,
- the tire has structural damage,
- The tire was replaced or the tire pressure
changed and it was not stored again
