@ Tips
The brake fluid reservoir is located under­
neath the cover.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moist ure from the a ir. If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
brake fluid w ill also decrease considerably and
decrease b raking performance .
Therefore, the brake flu id must be changed
every two years . Always use new brake fluid
which conforms to Federal Motor Vehicle
Standa rd "FMVSS 116 DOT 4".
The brake f lu id reservoir can be difficult to
reach, therefore, we recommend that yo u
have the brake f lu id changed by your author­
i zed
Audi dea ler . Your deale r has the co rrect
too ls, the right b rake fluid and the know-how
to do this fo r you.
_& WARNING
- Br ake fluid is po isonous . It must be s to r­
ed only in the closed orig inal con tainer
o ut of the reac h of c hildren!
- Br ake f ailure can resu lt from old or in ap ­
propr iate b ra ke fluid. Observe these pre ­
caut ions:
- Use on ly brake fluid that meets SAE
specif ication
J 1 703 and conforms to
Federal Motor V ehicle Sta ndard 116.
A lways check wi th you r auth o riz ed Audi
deale r to ma ke s ure you are using the
correct brake flu id . T he correc t type of
Checkin g and fillin g 275
brake f luid is also ind icated on t he
brake f luid rese rvoir.
- The bra ke fl uid must be new. Heavy use
of the brakes can cause a vapo r 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
safe ty. This co uld resu lt in an accide nt.
(1) Note
Brake fluid will damage the paint of your
vehicle.
@) For the sake of the environment
Because o f the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
required and the necessary expertise, we
recomme nd that you have the brake flu id
changed by you r autho rized Aud i deale r.
Battery
General information
U nder normal operating cond itions, the bat­
tery in your Audi does not need any ma inte­
nance. With
high outside temperatures or
long da ily drives we recommend that you have
the e lectrolyte level chec ked by an au thorized
Audi dealer or qualified wo rkshop . The elec­
t ro lyte level should also be che cked each time
t h e battery is cha rged
~ page 2 77.
Have the battery checked when you take your
vehicle in for se rv ice . You a re well advised to
replace a battery that is o lde r th an 5 years .
With certain types of airbag deployment, the ba tte ry is disconnected from the ve hicle elec­
t rical sys tem for safety reasons
~ A in Re­
pair, care and disposal of the airbags on
page 198.
Disconnecting the battery terminals
Some vehicle fu nctions (power window regu ­
lators, fo r example) are lost if the battery te r­
mina ls are disconn ected . T hese functions have
to be relearned after the bat tery termina ls are
conne cte d ag ain. To p revent t his, the battery .,.

could leak out of the ventilation open­
ings.
- If you get battery acid in your eyes or
on your skin, immediately rinse with
cold water for several minutes and get
medical attention.
- If you should ingest any battery acid,
seek medical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion and personal injury.
- When a battery is charged, it produces hydrogen gas which is explosive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­ tem, disconnect the negative ground ca­
ble .
- Before performing any work on the elec­
trical system, switch off the engine and
ignition as well as any electrical equip ­
ment . The negative cable on the battery
must be disconnected. If you are just go­
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change the cables -this could start a fire!
- Never charge a frozen or a thawed-out
battery. It could explode! If a battery has
fro zen, then it must be replaced. A dis-
Checking and filling 2 77
charged battery can freeze over at 32 °F
(0 oc).
-Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery .
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery.
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
batt ery.

Battery replacement
The new battery must have th e sam e specifi­
cations and dim ensions as the original equip­
ment battery.
Intell igent energy management in your vehi­
cle is respons ible for d istr ibuting the e lectr i­
cal energy throughout your vehicle
c::> page 231. The intel ligent e nergy ma nage­
men t system w ill keep the eng ine ba tte ry
ch arged be tte r th en vehicles w ithout t his sys ­
tem . To make sure the additional e lectrica l en ­
e rgy is available once again after you have
changed the battery, we recommend that you install batteries of the same type and man u­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations a re listed on the battery hous ing . Your
author ized dealer must code the battery in
the energy manageme nt system to enable yo u
to use the energy managemen t fu nctions co r­
rectly after rep lac ing the b attery .
If it is not poss ible to use a battery of this
type, the new battery must have the same ca­ p aci ty, voltage
(12 volts) , a mpe rage , con ­
s truc tion and pl ug sea ling.
W hen insta lli ng the battery, make sure the ig­
ni tion and all e lectr ical c ons umers a re turned
off.

pressure label lists the recommended cold
tire inflatio n pressures for the vehicle at its
maximum capacity we ight a nd the tires that
were on your vehicle at the time it was man ­
ufactured . For recommended t ire pressures
for normal load condit ions, please see chap ­
ter ~
page 284 .
-Turn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressure gauge on the valve.
- The tire pressures should only be checked
and adjusted when the tires are cold . The
s light ly raised pressures of warm tires must
not be reduced .
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the va lve stem cap on the valve .
When should I check the tire pressure ?
The correct tire pressure is especially impor ­
tant at high speeds . The pressure sho uld
therefo re be checked at least once a month
and a lways before start ing a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I adju st the tire pre ssures?
Ad just the tire pressure to the load you are
carrying. After changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then
store the new tire pressures i n the t ire pres­
sure mon itor ing system
~ page 300.
A WARNING
Incorrect tire pressures and/or unde rinfla­
tion ca n lead sudden tire failure, loss of
cont ro l, col lision, ser ious persona l inju ry
or even death.
- Whe n the wa rning symbo l
[ti] appears in
the instrume nt cl uster, s top and inspect
the tires.
- Incorrect tire pressure and/or underinfl a­
t ion can ca use inc reased t ire wear and
can affect the handling o f the veh icle and
stopp ing ability .
- Incorrect tire pressures and/or underin ­
flation ca n also lead to sud den tire fa il-
Tires an d wheel s 287
ure, including a blowout and sudden de­
flation, ca using loss of veh icle contro l.
- The driver is responsi ble for the co rrect
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­
ed on a sticker o n the dr iver's s ide B-pil­
lar .
- Onl y when all tires on the vehicle are fil­
led to the correct pressure, the t ire pres­
sure mon itor ing system can work cor­
rectly .
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage .
Therefore it is ess ential that th e drive r
observe t he spec ified t ire p ress ure val ues
for the tires and the cor rect pressures for
the func tion of the t i re p ress ure moni to r­
ing system.
- Always in flate tires to the recommen ded
a nd correct t ire p ress ure be fore dr iv ing
off .
- D riving with unde rinf lated tires bend
mo re, letting them get too hot resulting
in tread separation, s udden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the t ires will wear premat urely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, d rive at
red uced speed to the nearest service sta­
tion to check the t ire press ure and add
air as requ ired .
(D Note
Driving w ithout valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure that factory installed
valve s tem caps o n all whee ls are sec urely
mounted o n the valve .
@ For the sake of the environment
Underinflated tires will also increase the
fuel consumpt ion.

TPMS malfunction indicator is combined with
the low tire pressure tellta le . When the sys­
tem detects a malf unct ion, the te lltale will
flash for approximately one minute and then remain cont inuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction ex ists .
When the malfunct ion indicator is illuminat­
ed, the system may not be able to detect or
sig nal low t ire pressure as intended . TPMS
malfunct ions may occur for a variety of rea­
sons, including the installat ion of rep lace­
ment or alternate tires o r whee ls on the veh i­
cle that prevent the TPMS from funct io ni ng
p roperly. Always check the TPM S malfunct ion
tellta le after replacing one or more tires or
wheels on your vehicle to ensure that the re­ p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
