Checking and F ill in g
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the a ir. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after a peri­
od of time. The boiling point of the brake fluid
will also dec rease conside rably and dec rease
b ra ki ng perfo rman ce.
Therefore, the brake flu id must be changed
e ve ry
two y ear s.
Always use new b rake fluid wh ic h con­
forms to Fede ral Motor Vehicle Standard " FMVSS
1 16 DOT 4".
The brake fluid reservoir can be difficult to reach,
therefo re , we recommend that yo u have the
b rake fluid changed by your authori zed
Audi
dealer . Your dealer has the cor re ct too ls , the
righ t brake fluid an d the know-how to do t his for
you.
A WARNING
- Brake fluid is po isonous. It must be stored
only in the closed orig inal container out of
the reach of children!
- Brake fai lure can result from old o r inappro­
pr iate bra ke fluid . Observe these p recau­
t ions:
- Use on ly bra ke fluid t hat meets SA E speci­
fication
J 17 03 and confo rms to Fede ral
M otor Vehicle S tand ard 116 . Always check
wit h your author ized Audi dea ler to make
sure yo u are using the correct brake f lui d.
The cor rect type of b rake fluid is a lso indi­
cated on the bra ke fluid reservo ir.
- The brake fluid m ust be new. Heavy use of
the bra kes can cause a va por l ock if the
brake fluid is left in the system too long.
This ca n ser iously affect the effic iency of
the brakes as we ll as your safety . This
co uld res ult in an accident.
@ Note
Brake f lu id will damage the paint of y our vehi­
cle.

® For the sake of the environment
Because of t he prob lem of prope r disposal of
brake fluid as well as the special tools re­
q uired and the necessary expert ise, we rec­
ommend that yo u have the brake f lu id
changed by your autho rized Aud i dea le r.
Battery
General information
Under normal operating conditions, the battery
i n your A ud i does not need any maintenance .
With
high outside temperatures or long dai ly
drives we recommend that you have the e lectro­
l yte level checked by an aut horized Aud i dea ler or
qualified workshop . The e lectrolyte leve l should
also be chec ked each time the batte ry is cha rged
¢ page 198.
Have the battery checked when you take your ve­
hicle i n for service . You are well adv ised to re ­
place a battery that is older than 5 years .
With certain types of airbag deployment, the bat­
tery is disco nnected from the ve hicle elect rical
system for safety reasons
¢ A in Repair , care
and disposal of the airbags on page 141 .
Disconnecting the battery terminals
Some vehicle functions (power window reg ula­
tors, for example) are lost if the battery te rm i­
nals are d isconnected . These funct ions have to be
r elearned after the battery t ermina ls are con­
nected again . To prevent t his, the battery sho uld
o nl y be disconnected from the ve hicle e lectr ica l
system when absolute ly necessary fo r rep airs.
Vehicles not driven for long periods
If you do not drive your vehicle ove r a period of
several days or weeks, electrical components are gradua lly cut back or sw itched off . T his reduces
energy cons umption and mainta ins start ing ca­
pabili ty ove r a longer period¢
page 175.
Some of the convenience funct ions may not ope r­
ate, such as the inter ior lights or the power s eat
adjus tment . The conve nien ce f unct io ns w ill be
ava ila ble again when you tu rn on the ig nition an d
star t the eng ine. ..,..

Wheels
you would like to use different tires, please note that the tires
may perform differently even if
they are the same size¢
&-
~ If you would like to equip your
vehic le with a tire/rim combina­
tion that is different from what
was installed at the factory, con ­
sult with an authorized Audi dealer or authorized repair facili­
ty before making a purchase
¢ & .
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds .
.&._ 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
20 4
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 .
-Only use tires that are more than 6 years old when abso­lutely necessary and drive
carefully when doing so.
- 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

The Gross Axle W eight R ating
("GAWR") is t he maximum load
that can be applied at each of the
vehicle's two axles .
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carr ied in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen ­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage .
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
¢ page 206,
fig .171 .
A WARNIN G
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury , and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and in-
Wheels
crease the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance .
- Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash .
- Always make sure that the to­
ta l load being transported -
including the weight of a trail ­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the tota l weight of the pas­
sengers and luggage or other
things that you plan to transpor t
so that you can make sure that
your vehicle will not be overload- ed.

crisscross pattern,
from one bolt to the (ap­
proximately) opposite one, to keep the wheel
centered .
.. Perform the steps required after changing the
wheel
c::;, page 219, A~er changing a wheel.
The hexagonal socket makes it easier to remove
the wheel bolts from the rim. Care should be tak­
en when removing the reversible blade.
(D Note
When removing or installing the wheel, the
rim could hit the brake rotor/ceramic brake
rotor* and damage the rotor. Work carefully
and have a second person to help you.
(D Tips
- When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
c::;, page 223.
- The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
