Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢ A in Working in the engine compartment on
page 216.
.,. Read the brake fluid level from the brake fluid
reservoir
¢fig. 190, ¢page 218, fig. 186. The
brake fluid level must be between the "MIN "
and "MAX" markings.
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
¢page 218.
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 below
the "MIN" mark, the brake warning/indicator
light
1111 (U.S. models) ;II (Canadian models)
will come on¢
page 14. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified facility and the
cause corrected. If the brake fluid level is too
low, the brake warning/indicator light will illumi ­
nate. Contact an authorized Audi dealer
immedi­
ately.
Checking and Filling
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after ape ­
riod of time . The boiling point of the brake fluid
will also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed
every
two years . Always use new brake fluid which con­
forms 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 authorized
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 stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old or inappro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid that meets SAE 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 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 efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi-
cle.

Check ing and F illing
@ For the sake of the environment
Because of the prob lem of proper disposal of
brake fluid as we ll as the special tools re­
quired and the necessary expertise, we rec ­
ommend that you have the b rake fluid
changed by your author ized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
W ith
high outside temperat ures or long da ily
drives we recommend that you have the electro­
lyte level checked by a service fac ility . The elec­
trolyte level should also be chec ked eac h time
the battery is charged ¢
page 228 .
Have the battery checked when you take your ve­
h icle in for service. You a re well advised to re­
p lace a battery t hat is o lder than S years .
W ith certain types of a irbag dep loyment, the
battery is disconnected from the vehicle electr i­
cal system for safety reasons
¢ &. in Repair, care
and disposal of the airbags on page 157 .
Disconnecting the battery terminal s
Some vehicle functions (power window reg ula­
tors, for example) are lost i f th e battery termi ­
na ls are disconnected. These functions have to be
relearned after the battery termina ls are con­
nected aga in. To prevent th is , the batte ry shou ld
only be disconnected from the vehicle e lectr ica l
sys te m when abso lutely ne cessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
seve ral days or weeks, electrical components a re
gradua lly cut back or sw itched off . T hi s reduces

(D Tips
If yo ur vehicle is left standing for several
weeks at extreme ly low temperatu res, the ve­
hicl e battery should be re m oved a nd stor ed
where it will not freeze. This w ill preven t it
fro m bei ng damaged and hav ing to be re­

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.
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 al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

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. .,.

_& WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed .
Tire pressure monitoring
system
CD General notes
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
veh icle manufac turer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inf lation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire press ure te ll­
tale when one or more of your tires is significant­ l y under-inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a s ignifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Unde r-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 i t is the driver's re­
sponsib ility to ma inta in correct tire pressure,
even if under -inflation has not reached the level
to trigger illum inat ion of the TPMS low tire pres­
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPMS
mal function indicator to indicate when the sys­
tem is not operating properly. The TPMS mal ­
function indicator is combined w ith the low tire
pressure tellta le. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
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
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS ma lfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
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 mo/function .
Fig. 197 Instrume nt cluste r: indicator light with message
Us ing the ABS sensors, the tir e pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the press ure changes in one or more
tires , this is indicated in the instrument cluster
display with an indicator light
ti] and a message.
If only one tire is affected, the location of that
tire will be indicated.
T he tire press ures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle¢
page 250. The tire pressure moni­
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for ..,.
