recommend that you have the brake fluid
changed by your author ized Audi dealer.
Battery
General information
All work on the battery requires technical
knowledge!
F ig . 1 64 Eng ine co mpa rtment: Batte ry w it h cover*
The battery is located in the engine compart­
ment
c::> fig. 164 and is near ly m ain te nance­
fre e.
The condition of the battery is checked in the
framework of the inspection.
Disconnecting the battery
The batte ry should not be disconnected. Some
ve hicl e functions such as power windows are
unavailable if the battery termina ls are dis­
connected. These funct ions have to be re­
l earned after the battery term inals are con­
nected aga in. To prevent this, the battery
should only be disconnected from the vehicle
electrical system if absolutely necessary .

If you do no t drive your vehicle for several
days or weeks, electrical consumers are grad ­
u ally scaled back or switched off . This reduces
energy use and ensures the vehicle will be
able to start after long periods of time
c::, page 167. Some convenience functions
such as opening w it h the remote control key
may not be available. These conve nience func­
tions wi ll be available again once you switch
the ignit io n on and sta rt the engine. Even
whe n consume rs a re switched off, the battery
will become deeply discharged by stand -by
power consumers if the vehicle is not driven
for several months . Deep discharging results
in a chemical reaction that destroys the inside
of the battery. The battery must be charged
every month to prevent th is

not disconnect the battery or the anti-t heft
alarm system* will not work .
Winter operation
Cold weather places higher demands on the
battery. This results in reduced starting abili­
ty. Have the battery checked and recharged if
necessary befo re the cold weather begins.
Avoid unnecessary power consumpt ion, par­
ticularly in city traffic or when traveling only
short distances . Let your authorized Audi
dealer check the capacity of the vehicle bat­
tery before winter sets in
c::, page 209 . A well
c harged bat tery will not o nly prevent s tarti ng
problems when the weather is cold, but will
also last longer .

208 Check ing and filling
for questions about the battery -danger
of acid burns and explosion hazard!
- The battery must not be opened! Do not try to change the battery's liq uid level ,
otherwise detonating gas will escape
from the battery- explosion hazard!
- The AGM battery in the luggage com­
partment cannot leak, because the elec­
trolyte for th is battery is absorbed into a
spec ial glass mat . Th is leak-proof battery
must not be replace with a conventional
battery .
- Make sure the ventilat ion hose on the
s ide of the battery is connected, other ­
wise fumes or battery acid can leak out .
- Battery ho lder and terminals a lways
have to be secured correctly .
- Before all work on the battery follow the
warning s below c> &. in Working on the
battery on page 208 .

- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
- When working on the battery, be s ure
not to short-circu it the terminals w ith
too ls or othe r metal objects. Th is would
cause the battery to heat up very quickly,
which could lead to damage or explosion
-
and pe rsonal injury . ~

-When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca­
ble.
- Before performing any work on the elec­
trical system, switch off the engine and
ignition as well as any electrical equip­
ment. The negative cable on the battery
must be disconnected. If you are just go­
ing to replace a light bulb, then it is
enough to switch off the lights.

Charging of battery
All work on the battery requires technical knowledge!
Fig. 165 E ngine compart ment: conne ctors for a charg­
er and jump start cables
A charged battery ensures good starting per­
formance . A discharged battery can
freeze at
temperatures of only
O 0C. A frozen or thawed
battery must be replaced, as the battery
housing may be cracked due to freezing and
could therefore leak acid.

Chargi ng the b attery
Only use chargers with a m ax im um cha rg in g
v oltage o f
14.8 V. The battery connecting ca­
bles do not need to be disconnected. Do not
open the battery when charging.
Read all of the manufacturer's instructions for
the charger before charting the battery.
It is not necessary to remove the battery from
the engine compartment, and it is a lso not
necessary to disconnect the cables.
Normally, a battery should be charged at no
more than 10 percent of its rated capacity.
For example, a charging current of 4.5 amps
wo uld be used on a battery rated at 45 Ah.
Rated capacity of the battery in your veh icle is
listed on the battery housing .
The battery caps shou ld
not be opened when
cha rg ing a battery.
_& WARNING
Cha rging a battery can be dangerous.
- Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice .
Allow a frozen battery to thaw o ut first .
- Do not reuse batteries which we re fro­
zen. They must be replaced. The battery
housing may have cracked and weakened
when the battery froze.
- Charge the battery in a we ll ventilated
area. Keep away from open f lame or elec­
trical spark. Do not smoke. Hydrogen gas generated by the battery is explosive. -
To reduce the danger of exp losion, never
connect or d isconnect charger cab les
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent techn ic ian with the proper equip­
ment.
- Battery acid that may sp ill dur ing charg­
ing should be washed off with a solut ion
of warm water and baking soda to neu­
tralize the ac id.
{[) Note
-Make sure that the gas venting hose is
always connected to the or iginal opening
on the battery s ide. Otherwise gasses or
battery acid could leak out.
- Never use a fast charger as a booster to start the engine. This will seriously dam­
age sensitive electron ic components,
such as contro l units, re lays, radio, etc.,
as well as the batte ry charger.
- T he vehicle may be optionally equ ipped
w ith a gel battery, wh ich can only be
charged at a cons tant current-lim ited
voltage . To prevent damage to the bat ­
tery and the electronics system, a gel battery that is connected must under no
circumstances be charged with a quick
charger.
{!) Tips
- The vehicle battery must not be charged
with a standard small charger that pl ugs
into the outlet.
- Only charge the battery through the con­
nections in the engine compartment.
Battery replacement
The new battery must hove the some specifi­
cations as the old one.
Intelligent energy management in your vehi­
cle is responsible for distributing the electri­
ca l energy throughout your vehicle
¢
page 167. The intelligent energy manage-
ment system will keep the engine battery .,..

charged better then vehicles without this sys­
tem . To make sure the additional e lectrica l en ­
ergy is available once again after you have
changed the battery, we recommend that you install batteries of the same type and manu­
facture only (the same as those installed at
the t ime your vehicle was delivered). Specifi­
cations are listed on the battery hous ing . Your
authorized dealer must code the battery in
the energy management system to enable yo u
to use the energy management functions cor­
rectly after replacing the bat tery.
If it is not possible to use a battery of this
type, the new battery must have the same ca­
pacity, voltage (12 volts) , amperage, con ­
struction and plug sealing.
We re commend that you use ma intenance­
free or
cy cle -re sis tant /le ak-proof batteries
that conform to the standards TL
825 06
(from December 1997) and VW 7 SO 73 (from
Aug ust 2001).
When insta lling the bat tery , make sure the ig­
n ition and all e lectrica l consumers are turned
off .
CD Note
-Make sure tha t the gas venting hose is
always connected to the o riginal open ing
on the battery side . Otherwise gasses or
battery acid could leak out.
- Battery mounts and clamps m ust always
be secured correctly.
- Read and follow the warnings under
C? page 208, Working on the battery be ­
fore performing any work on the battery .
@ For the sake of the environment
Because of the problem of proper d isposa l
o f a battery, we recommend your author ­
ized Audi dealer change the batte ry for
you. Batteries contain su lfuric ac id and
lead and must always be disposed of prop­
erly in compliance w ith all environmental
regu lations . D isposing of vehicle batte ries
improperly is very dangerous to the envi­
ronment. Make sure that the removed bat-

Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that a ll-impo rtant contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
Avoiding damage I f you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one side, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the sid ewa ll, that po int in the direc­
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.
For more information ¢
page 241.
A WARNING
-New tires or tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a co llision and ser ious personal
in jur ies, d rive w ith special ca re fo r the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fl ation, c rashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- T ires age even if they are not being used
an d can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.

-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
