Checking brake fluid level
Fig . 197 Engine compartment: cove r on the brake fluid
reservo ir
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ¢&. in Working in the engine compart­
ment on page 225.
,.. Read the brake fluid level from the brake
fluid reservoir¢
fig . 197, ¢ page 22 7,
fig. 193.
The brake flu id level must be be­
tween the "MIN" and "MAX" markings.
The location of the brake flu id reservoir can be
seen in the engine compartment illust rat ion
¢ page 227.
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¢
page 15. Do not con­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized A udi dealer or other quali­
fied facility and the cause corrected.
If the
brake fluid level is too low, the brake warning/
indicator light will illuminate. Contact an au­
thorized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an 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 decrease conside rably 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 "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi dealer. Your dealer has the correct
tools, the right brake fluid 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 fluid. Observe these pre­
cautions:
- Use only brake fluid that meets SA E
specification
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 f luid is also indicated on the
brake fluid 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 seriously affect the effi­
c ie ncy of the brakes as well as your
safety. This could resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

@ For the sake of the environment
Because of the pr oblem of proper d isposa l
of brake flu id as we ll as the special tools
requ ired and the necessary expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer .
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level shou ld also be
checked each time the battery is charged
¢ page 237.
Have the battery checked when you take your
ve hicle in for service . You are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢.&.
in Re ­
pair, core and disposal of the airbags on
page 163.
Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this , the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods
If you do not drive you r vehicle over a period
of severa l days or weeks, elec trical compo­
nen ts are gr adually cut b ack o r swi tched off .

yo u sw itch on the ign ition and start the en­
gine.
Winter operation
D ur ing the w inte r mon ths, bat tery ca pa city
tends to decrease as tempera tures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear window de­
fogger, etc., are used mo re often.
Avoid unnecess ary powe r consumpt ion, pa r­
ticu lar ly in city traffic o r when traveling only
sho rt distances. Let yo ur authorized A udi
dealer check the capacity of the vehicle bat ­
tery before w inter sets in¢
page 23 7. A well
charged battery will no t on ly prevent star tin g
problems w hen the weather is cold, but w ill
also last longer .
@ Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
stored where it will not freez e. This will
p reve nt it from be ing dam aged and having
to be repl aced .
Working on the battery
Be especially careful when working on or near
the bat tery.
The battery is located in the luggage compar t­
ment under the floor . B efo re you che ck any­
thi ng in the luggage compartment,
read and
heed all WARNINGS
¢ .&, .
Always heed the safety warnings , when work­
i ng on the veh icle batte ry or t he vehicle e lec­
t rical sys tem to p reven t inju ry.
The following WARNINGS are very
important when working on the battery:
Always heed the following WARNING SYM· BO LS and safety precautions when working

If you wish to improve comfort
when operating the vehicle at normal load (up to 2/3* occu­
pants), you can adjust tire
pressures to those specified
for normal vehicle load. Before
operating the vehicle at maxi­ mum load, you must increase
the tire pressures to those
specified for maximum vehicle load
c> .&. .
Bear in mind that the tire pres­
sure monitoring system can on­
ly monitor the tire pressures
you have stored. The system does not recognize the load
condition of your vehicle.
The effectiveness of the tire pressure monitoring system
will be impaired if you store normal load pressures but then
operate the vehicle at its maxi­
mum load

Tire pressure indicator appears
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. 205 Display: underinflation warning
Fig. 206 Display: System malfunction
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­ ference and vibration characteristics of the in­
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instru­
ment cluster with a warning symbol
rD] and a
message
c:> fig . 205.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e.g. when switching between partial
and fu ll load pressure) or after changing or re­
placing a tire on your vehicle
c:> page272 . The
TPMS indicator only monitors the tire pres­
sure that you have previously stored. You can
find the recommended tire pressures for your
vehicle on the label on driver's side 8-pillar
c:>page247.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
Tires and wheels 2 71
- the tire has structural damage,
- the tire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset

Ifljl appears
after switching the ignition on or while driving
¢
fig. 206 and the indicator light rD] in the in­
strument cluster blinks for approximately one
minute and then stays on, there is a system
malfunction. Attempt to store the correct tire
pressure
c:> page 272. If the indicator light
does not turn off or if it turns on shortly
thereafter, immediately drive your vehicle to
an authorized Audi dealer or authorized repair
facility to have the malfunction corrected.
_& WARNING
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label<=:>
page 247 . Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must check the tire pressures regularly.
