Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a high-quality oil
which can usually be used throughout the entire
year .
Q) Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set fo rth in the Audi Owner's
Manual and Wa rranty
& Maintenance booklet.
- Use only a high qua lity eng ine oi l th at ex-
pressly complies with the Audi oil qua lity
stan dard specified for your vehi cle's engine.
Using any o ther oil can cause serious engine
damage .
- Do not mix any lubricants o r other addit ives
i nto the engine oil. Doing so can cause en
gine damage.
(D Tips
I f you nee d to add oi l and there is none availa
ble that meets the Audi o il qu ality st andard
your engine requires, you may ad d a total of
no more than 0 .5 quart/liter of a high-quality
"synthet ic"oil that meets the following speci
fications.
- ACEA A3 o r API SM with a viscosity g rade of
SAE OW-30, SAE 5W-30 or SAE 5W-40.
- For more information about engine oi l that
has been approved for your vehicle, please

Engine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all of
its moving parts .
In order to provide effective lubrication and cool
ing of internal engine components, all internal
180
combust ion engines consume a certa in amo unt
of oil. Oil consumption varies from engine to en
gine and may change significantly over the life of
the engine. Typically, engines w ith a specified
break-in period (see
c:::;, page 159) consume more
o il dur ing the break-in per iod than they consume
af ter o il consumption has stab ilized .
Under normal conditions, the rate of oil con
sumption depends on the quality and viscos ity of
the oil, the RPM (revo lutions per m inute) at
wh ich the engine is operated, the amb ient tem
perature and road condit ions. Further factors a re
the amount of o il di lution from wate r co ndensa
tion or fue l resid ue an d the oxidation level of the
o il. As any engine is sub ject to wear as mileage
builds up, the oi l cons umption may increase over
time unt il replacement of worn components may
become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil consumption can be estab
li shed or specified. The re is no alternative to reg
u lar and frequent checking of the oi l level, see
Note.
If the yellow engine oil level warning symbo l Ell
in the instrument cluster lights up, you sho uld
check the oil level as soon as possible
c:::;, page 181. Top off the oil at your earliest con
venience
c:::;,page 181.
A WARNING
Before you check anyth ing in the e ng ine com
partment, always read and heed all WARN
I NGS
c:::;, .&. in Working in the engin e compart
ment on page 177.
(D Note
Driving w ith an insuffic ient oil level is likely to
cause severe damage to the eng ine.
(D Tips
- The oil pressure warn ing d isplay. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en
g ine at regular int ervals , pr eferably each
time you refuel, and alway s before going
on a long trip .

Checking and Filling
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick
glance.
Fig. 153 Eng ine compartment: Cover on the brake fluid
r eservoir
Before you check anything in the engine compart
ment,
always read and heed all WARNINGS
¢ A in Working in the engine compartment on
page 177.
., Read the brake fluid level from the brake fluid
reservoir
<=> fig . 153, ¢page 179, fig . 149 . The
brake fluid level must be between the
" MIN"
and "MAX " markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the left
side ¢
page 179 .
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 (USA models:
1111 , Canada models:. )
will come on¢
page 13 . Do not continue to oper
ate the vehicle . The complete brake system
should be thoroughly checked by an authorized
Aud i dealer or qualified workshop and the cause
corrected. If the brake fluid level is too low, the
brake warning/indicator light w ill illuminate.
Contact an author ized Audi dealer
immediately.
(D} Tips
The brake fluid reservoir is located under
neath the cover.
186
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 po int of the brake fluid
will a lso 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 Feder-al 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 stored
only in the closed original container out of
the reach of children!
- Brake fai lure can result from o ld or inappro
priate brake fluid. Observe these precau
tions:
- Use only brake fluid that meets SAE speci
fi cation
J 1703 and conforms to Federal
Motor Veh icle 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 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 .
lilJJ,

@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as we ll as the special toots re
quired and the necessary expertise, we rec
ommend that you have the brake fluid
changed by your authorized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the electro
lyte level checked by an authorized Audi dealer or
qualified workshop. The electrolyte level should
also be checked each time the battery is charged
c> page 189.
Have the battery checked when you take your ve
hicle in for serv ice. You are well advised to re
place a battery t hat is older than 5 years.
With certain types of airbag deployment, the battery is disconnected from the vehicle electri
cal system for safety reasons
c> & in Repair, care
and disposal of the airbags on page 125 .
Disconnecting the battery terminals
Some vehicle functions (power window regula
tors, for example) are lost if the battery termi nals are disconnected. These functions have to be
relearned after the battery terminals are con
nected again. To prevent th is, the battery should
only be disconnected from the vehicle e lectr ica l
system when abso lutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. This reduces
energy consumption and maintains starting ca
pability over a longer pe riod
c> page 157.
Some of the conven ience functions may not oper
ate, such as the interior lights or the power seat
adjustment. The convenience functions will be
available again when you turn on the ignition and
start the engine.
Checking and Filling
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop . This is be
cause more power is also consumed while start
ing, and the headlights, rear window defogger,
etc., are used more often.
Avo id unnecessary power consumption, particu
larly in city traffic or when traveling only short
distances . Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in
c> page 189. A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer .
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve
hicle battery should be removed and stored
where it w ill not freeze. This will prevent it
from be ing damaged and having to be re
placed.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the engine compart
ment . Before you check anything in the engine
compartment ,

When the malfunction indicator is illuminated,
the system may not be ab le to detect or signal
low tire pressure as intended . TPM S malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
