Before you check anything i n the engine com­
partment,
a lw ays read and heed all W ARN ­
ING S 9 A in Working in the engine compart ­
ment on page
22 7.
~ Read the brake fluid level from the brake
fluid reservoir
9 fig . 197, 9 page 229,
fig. 193.
The brake fluid level must be be ­
tween the "MIN" and "MAX" markings .
The location of the brake fl uid reservo ir can be
seen in the engine compartment illustrat ion
9 page229.
The fluid level may drop slightly after some
time due to the automatic adj ustment of the
b rake pads. This is not cause for alarm.
I f the brake fluid level falls
considerably be­
l ow the "MIN " mark, the brake wa rning/indi­
cator ligh t
1111 (U.S. models)/ . (Canadia n
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 Audi dealer or other quali­
f ied fac ility and the cau se corrected.
If the
brake fluid level is too low, the brake warning/
indicator light will illuminate . Contact an au ­
thor ized Audi dealer
imm ediat ely .

Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs mois ture from the air. If
the wa ter 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
ev ery 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 dealer . 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
spec ificat 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 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
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 .
.

238 Checking and filling
@ For the sake of the environment
Because of the problem of proper disposal
of brake fluid as we ll as the special tools
required and the necessary expertise, 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 drives we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level should also be
checked each time the battery is charged
<=:> page 240.
Have the battery checked when you take your
vehicle in for service . You are well adv ised to
replace a battery that is older than 5 years .
With certain types of airbag deployment, the battery is disconnected from the vehicle elec­
tr ical system for safety reasons
c::> & in Re­
pair, care and disposal of the airbags on
page 165.
Disconnecting the battery terminals
Some vehicle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are disconnected. These functions have
to be relearned after the battery terminals are
connected again. To prevent this , the battery
should only be disconnected from the vehicle
e lectrica l system when absolutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period
of severa l days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main­
tains starting capability over a longer period
c::> page 202. Some of the convenience func­
tions may not operate, such as the interior
lights or power seat adjustment. The conven- ience
functions will be available again when
you switch on the ignition and start the en­ gine.
Winter operation
During the winter months, battery capac ity
tends to decrease as temperatures drop. This
is because more power is a lso consumed whi le
starting, and the headlights, rear window de­
fogger, etc., are used more often.
Avoid unnecessary power consumption, par­
ticularly in city traffic or when traveling only
short distances. Let your authorized Audi
deale r check the capacity of the vehicle bat ­
tery before winter sets in
c::> page 240 . A well
charged battery will no t only prevent star ting
problems when the weather is cold, but will
also last longer .
@ Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it w ill not freeze. This will
prevent it from be ing damaged and having
to be replaced .
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor . Before you check any­
thing in the luggage compartment,
read and
heed all WARNINGS
c::> .&,.
Always heed the safety warnings , when work­
ing on the vehicle battery or the vehicle elec­
trical system to prevent injury.
The following WARNINGS are very
important when working on the battery:
Always heed the following WARNING SYM-
BOLS and safety precautions when working
on the battery.
®
Always wear eye protection.

262 Tires and wheels
remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is ill uminat­
ed, the system may not be able to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea­
sons , including the installat ion of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunction
tellta le after replacing one or more t ires or
wheels on your veh icle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indi cator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 205 Display: underi nflatio n warn ing
Fig. 206 Display: System mal functio n
Using the ABS sensors, the tire pressure moni­
toring system compares the t ire tread circum­
ference and vibration characteris tics of the in­
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the i nstru- ment
cluster with a warning symbol
RE and a
message
c:> fig. 205 .
The tire pressure monitoring system must be
reset via MMI each time the p ress ures are ad­
justed (e.g . when switching between partial
and full load pressure) or after changing or re­
plac ing a tire on your vehicle
c:> page 263 . 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 dr iver's side 8-pillar
<=:>page 247 .
Tire tread circumference and vibrat ion charac­
teristics can change and cause a tire pressure
wa rning if:
- the t ire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat -
ed or replaced but the TPMS was not reset
<=:> page 263.
