Checking brake fluid level
Fig. 192 Engine compartment : cove r on the brake fl uid
reservo ir
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ~ .&. in Working in the engine compart ­
ment on page 224.
.,. Read the brake fluid level from the brake
fluid reservoir~
fig. 192 , ~ page 226,
fig.
188. The brake fluid leve l must be be­
tween the "MIN" and "MAX" markings .
The location of the brake flu id reservoir can be
seen in the engine compartment illustrat ion
~ page 226.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads . Th is is not cause for alarm.
I f the brake fluid level falls
considerably be­
lo w the "MIN" mark, the brake wa rning/indi­
cator light
1111 (U.S. models)/ . (Canadian
models) will come on~
page 15. Do not con­
tinue to operate the vehicle. The comp lete
brake system should be thoroughly checked
by an authorized Audi dealer or other quali­
fied facility and the ca use corrected. If the
brake fluid level is too low, the brake warning/
indicator light w ill illuminate . Contact an au ­
thorized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the air. If
the water 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 fluid will also decrease considerably and
decrease braking pe rformance .
Therefore, the brake fluid must be changed
every two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "FM VSS 116 DOT 4".
The brake fluid reservoir can be diff icult 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 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 fluid. Observe these pre­
cautions:
- Use only brake fluid that meets SA E
specification
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 flui d is also ind icated 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 effi­
c ie ncy of the brakes as well as your
safety. This could result in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

@ For the sake of the environment
Because of the pr oblem of proper d isposa l
of brake flu id as we ll as the special tools
requ ired and the necessary expert ise, 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 dr ives we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level shou ld also be
checked each time the battery is charged
¢ page 237.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢.&.

pair, core and disposal of the airbags on
page 163.
Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this , the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods
If you do not drive you r vehicle over a period
of severa l days or weeks, ele ctrical compo­
nen ts are gr adually cut b ack o r swi tched off .

yo u sw itch on the ign ition an d start the en­
gine.
Winter operation
D ur ing the w inte r mon ths, bat tery ca pa city
tends to decrease as tempera tures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear window de­
fogger, etc., are used mo re often.
Avoid unnecess ary powe r consumpt ion, pa r­
ticu lar ly in city traffic o r when traveling only
sho rt distances. Let yo ur authorized A udi
dealer check the capacity of the vehicle bat ­
tery before w inter sets in¢
page 23 7. A well
charged battery will no t on ly prevent star tin g
problems w hen the weather is cold, but w ill
also last longer .
@ Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
stored where it will not freez e. This will
p reve nt it from be ing dam aged and having
to be repl aced .

Be especially careful when working on or near
the bat tery.
The battery is located in the luggage compar t­
ment under the floor . B efo re you che ck any­
thi ng in the luggage compartment,

unbalanced, resulting in vib rations you can
usually feel through the steering wheel.
Unba lanced wheels mus t be rebalanced to
avoid excessive wea r on s teer ing, suspens ion
and tires. A wheel must a lso be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Inco rrect whee l alignment can cause exces­
sive tire wea r, impair ing t he safety of the veh i­
cle. If t ires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All-wheel d rive
Ve hicles w it h quattro must always have tires
of the s ame s ize, construction and tread type.
F or detai ls see
¢ page 198 .
A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any t ire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard , they do
not grip well on wet roads and increase
your risk of"hydrop lan ing" and loss of
co ntrol.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
sp eeds.
- Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used ti res may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss o f vehicle control.

New tires and replacing tires and wheels
New tires and wheels have to be broken in.
