Before you check anything in the engine com­
partment,
a lwa ys read and heed all WARN­
ING S c:> .&.. in Working in the engine compart­
ment on page 231 .
~ Read the brake fluid level from the brake
fluid reservoir
c:> fig. 202, <=> page 233,
fig . 198 .
The brake flu id level must be be ­
tween the "MIN" and "MAX" markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the
left side
c::> page 2 33 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads . This is not cause for alarm .
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (U.S. models:~, Canadian
models: .) will come on
c> page 18 and
c::> page 29 . Do not continue to operate the ve­
h icle. The complete brake system should be
thoroughly checked by an authorized Aud i
dealer o r qualified workshop and the cause
corrected.
If the brake fluid level is too low,
the brake warning/indicator light will illum i­
nate . Contact an authorized Audi dealer

Changing brake fluid
Have the brake fluid changed by on experi­
enced technician .
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also dec rease considerably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
every two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "F MVSS 116 DOT 4".
The brake fluid reservo ir can be d iff icult to
reach, the refore, we recommend that you
have the brake fluid changed by your author­
i zed
Audi d ealer. Your dealer has t he correct
tools, the right brake fl uid and the know-how
to do this for you .
A WARNING -.
-Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f luid. Observe these pre­
cautions:
- Use only brake fluid that meets SAE
spe cificat ion
J 1 7 03 and conforms to
Federa l Moto r Ve hicl e Standard 116.
Always check with yo ur authorized Audi
dealer to make sure yo u are using the
correct bra ke fluid. The correct type of
brake f luid is also indicated on the
brake f luid 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
l ong . This can seriously affect the effi­
c iency of the brakes as well as your
safety. Th is cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

242 Checking and filling
@ For the sake of the environment
Be cause of the problem of proper disposa l
of brake flu id as we ll as the special tools
req uired and the necessary expert ise, we
recommend that you have the b rake fluid
changed by your author ized Audi dealer.
Battery
General information
Unde r normal operating conditions, the bat ­
tery in your A udi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the elect ro lyte level checked by an authorized
Aud i dea ler o r qualified workshop . The elec­
trolyte leve l sho uld a lso be c hecked each t ime
the battery is c harged ¢
page 244.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a bat tery that is older tha n 5 yea rs .
W ith certa in types of a irbag deployment, t he
battery is d isconnected from the vehicle elec­
tr ica l system fo r safety reasons ¢

Hybr id d rive *: you can find important i nforma­
tion about the high voltage battery under
¢ page 97.
Disconnecting the battery terminals
Some veh icle functions (power w indow regu­
lators, for example) are lost if the battery ter­
minals a re discon nected. These functions have
to be re learned after the ba tte ry term inals a re
connect ed aga in. To prevent this , the battery
should only be d isconnected from the vehicle
e lec tric al sys te m whe n absolu tely necessa ry
for rep airs.
Vehicles not driven for long periods
If yo u do not dr ive you r vehicle over a pe riod
of severa l days or w eeks, ele ct rical com po­

Winter operation
Du ring the winte r mon ths, bat tery ca pac ity
tends to dec rease as tem peratures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear wi ndow de­
fogger, etc ., are used more often.
Avoid unnecessary powe r consum ption, pa r­
t icu lar ly in city traffic or when traveling only
sho rt distances. Let your authori zed Aud i
dealer check the capacity of the vehicle bat ­
te ry before winter sets in ¢
page 244. A well
c h arged battery will not on ly preven t starti ng
problems when the wea ther is cold, but w ill
also last lo nger.
Working on the battery
Be especially careful when working on or near
the ba ttery.
The battery is located in the luggage compart­
me nt under the floor . B efo re you c hec k any­

A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive problems. Wash hands after han­
dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is switched on or when
the engine is running, otherwise, you will
damage electronic components in the
electrical system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing ", oth­
erwise it will be damaged and will then have to be replaced .
Battery charging
Starting the engine requires a well charged
battery.
Fig. 203 E ng ine compar tment: Connectors for charger

page 231.
• Remove th e cover (D by pressing on the ar­
row
¢fig. 203.
• Open the cover @on the positive terminal.
• Connect the charger co nnectors according to
the instructions to the
jump start bolts .
(Bolts under the cover = "pos itive", Bolts
with hex head= "negative ").
• Only now plug the mains lead for the charg­
ing equipment into the wall outlet and turn
it on¢ .&_.
• Make sure the charging rate is not over
30 amps/14.8 Volt.
• When the battery is fully charged: T urn the
charg ing equipment off and remove the
mains lead from the wall outlet.
• Now remove the clamps for the charging
equipment.
• Close the cover @on the positive terminal
and re-install the cover
(D.
• Close the hood¢ page 231.
A discharged battery can freeze at tempera­
tures of only 32 °F (0 °C). Allow a frozen bat­
tery to thaw completely before attempting to
charge it¢.&.. However, we recommend not
using a thawed battery again because the bat­
tery casing can be cracked due to ice forma­
tion and can leak battery acid.
Battery charging (Maximum charging rate
of 30 amps/14.8 Volt)
When charging at low voltages (e.g. with a
trickle charger), the battery cables do not
have to be disconnected first. The battery
caps should
not be opened when charging a
battery.
It is not necessary to remove the battery from
the luggage compartment.
Fast charging the battery (charging rate
above 14.8 Volts)
For technical reasons do not use a battery
c h arger that uses voltage greater than 14.8
Volts to charge your vehicle's battery.
A WARNING
--
Charging a battery can be dangerous. ~

-Always follow the operating instructions
provided by the battery charger manu­
facturer when charging your battery.
- Never charge a frozen battery.
It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
trical spark. Do not smoke . Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent technician with the proper equip­
ment.
- Battery acid that may spill during charg­
ing should be washed off with a solution
of warm water and baking soda to neu­
tralize the acid.
(D Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as control units, relays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
Intelligent energy management in your vehi­
cle is responsible for distributing the electri­
cal energy throughout your vehicle
¢ page 203. The intelligent energy manage­
ment system will keep the engine battery
charged better then vehicles without this sys­
tem . To make sure the additional electrical en­
ergy is available once again after you have
changed the battery, we recommend that you
Checking and filling 245
install batteries of the same type and manu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­ cations are listed on the battery housing . Your
authorized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­
rectly after replacing the battery .
If it is not possible to use a battery of this
type , the new battery must have the same ca ­
pacity, voltage (12 volts), amperage, con­
struction and plug sealing .
When installing the battery, make sure the ig­ nition and all electrical consumers are turned
off .
(D Note
-Make sure the ventilation hose on the
side of the battery is connected, other­
wise fumes or battery acid can leak out .
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery. Installing a different type of
battery can cause problems in the vehi­
cle electrical system. When replacing the
vehicle battery, always install one with
the same specifications as the original
battery.
@ For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author­
ized Audi dealer change the battery for
you. Batteries contain sulfuric acid and
lead and must always be disposed of prop­
erly in compliance with all environmental
regulations. Disposing of vehicle batteries
improperly is very dangerous to the envi­
ronment. •

wound back down as far as it will go.
& WARNING
Improper use of the vehicle jack* can
cause serious personal injuries.
- Never use the jack* supplied with your
Audi on another vehicle, particularly on a
heavier one . The jack* is only suitab le for
use on the vehicle it came with . -
Using a bumper jack to raise the vehicle
will damage the bumper system. The
jack may slip, causing injury.
- Never support your vehicle on cinder
blocks, bricks or other objects. These
may not be able to support the load and
could cause injury when they fa il.
- Never start or run the engine while the
veh icle is supported by the jack*.
- If you must work under the vehicle, al­
ways use safety stands specifically de­
signed for this purpose.
- Never use the hexagonal socket in the
handle of the screwdriver to loosen or
tighten the wheel bolts.
- Always make sure the inflatable spare
tire* and even a flat t ire are secured in
place and not loose, otherw ise they
could fly forward, causing personal injury
to passengers in the vehicle in an acci­
dent or sudden maneuver.
@ Tips
Some of the on board items listed above
are provided on certain models only or are
optiona l extras.
Folding chocks

@ Tips
-Do not operate the compressor for more
than 12 minutes continuously, otherwise it can overheat. Once the compressor has
cooled, you can continue to use it.
- If sealant has spilled out, let it dry and
then you can remove it by peeling it away
like a foil.
- Remember to obtain a new bottle of
sealant from your authorized Audi dealer
after repairing a tire. After this, the func­
tionality of the tire repair set is restored.
- Obey all laws.
Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang­
ing a wheel.
.,. After you experience a tire failure, pull the
car well away from moving traffic and try to
reach
level ground before you stop¢_& .
.. All passengers should
leave the car and
move to a safe location (for instance, behind
the guardrail) ¢
_&.
.. Engage the parking brake to prevent your
vehicle from rolling unintentionally¢_&.
.. Move
selector lever to position P ¢ _& .
.,. If you are tow ing a trai ler: unhitch the trail­
er from your vehicle.
