flui d rese rvoir
Be fore you check a nything in th e en g in e co mpart ment,
always read and heed all WARNINGS=> & in "Working in
t h e eng ine compartment" on
page 331.
- Read the brake fluid l eve l from the brake fluid reservoir
=> fig. 288. The brake flu id level mus t be between the
"MIN" and "MAX" markings.
The brake fluid reservoir is locate d at the rear partition of the engine
compartment on the left side=>
page 332.
The fluid level may drop slightly after some time due to the auto
ma tic adjustment of the brake pads. This is not cause for alarm .
If the brake fluid leve l falls
considerably below the "MIN" mark , the
brake warning/indicator light (U.S. models:
BRAKE , Canadian models:
«D> l will come on=>
page 23 and=> page 32 . Do not continue to
operate the vehicle. The complete brake system should be thor
oughly checked
by an author ized Audi dealer or qua lif ied workshop
and the cause corrected . If th e brake fluid level is too low, the brake
warning/indicator light w ill illumi nate. Contact an authorized Audi
dea ler
immedi ately .
[ i ] Tips
The brake fluid reservoir is located underneath the cover .•
Changing brake fluid
Have the brake fluid changed by an experience d techni
cian.
Brak e fluid absorbs mois ture from the air. If the wate r conten t in the
brake fluid is too high, corrosion in the brake sys tem may res ult
after a period of time . The boiling point of the brake fluid will also
decrease conside rably and decrease braking performance .
Therefore , the brake fluid mus t be changed
every two year s. Always
use new brake fluid which conforms to Federal Motor Vehicle S tan
da rd "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficul t to reach, therefore , we
recommend that y ou have the brake fluid changed by your autho
rized
Audi deal er. Your dealer has the correct tools, the right brake
fluid and the know -how to do this for you .
& WARNING
• Brak e fluid is poi sonou s. It mu st be stored only in the clo sed
o riginal conta iner out of the rea ch of children! ..,.

0 Note
Brake fluid will damage the paint of your vehicle .
For the sake of the environment
Because of the problem of proper disposal of brake fluid as well as
the special too ls required and the necessa ry expertise, we recom
mend that you have the brake fluid changed by your authorized Audi
dea ler .•
Battery
General information
Under normal operating condi tions, the battery in your Audi does
not need any maintenance. With
high outside temperatures or long
daily drives we recommend that you have the e lectrolyte level
checked by an au thorized Audi dealer or qualified workshop . The
e lectrolyte level should also be ch ecked each time the battery is
charged ~
page 344.
Have the battery checked when you take your vehicle in for service .
Yo u are well advised to replace a battery that is o lder than 5 years .
With certain types of airbag dep loyment, the battery is discon
nected from the vehicle electrical system for safety reasons~
& in
"Repair, care and disposal of the airbags" on
page 255.
Disconnecti ng th e batt ery termin als
Some vehicle functions (power window regulators , for example) are
lost if the battery termina ls are disconnected. These functions have
to be relearned after the battery terminals are connected again . To
prevent this, the battery should only be disconnected from the
vehic le electrical sys tem when abso lutely necessary for repairs .
Vehicles not driven for long per iods
If you do not drive your vehicle ove r a period of several days or
weeks, electrical components are gradually cut back or switched off .
T his reduces energy consumption and maintains starting capab ility
over a longer period
~ page 295 .
Take i nto consideration that whe n you u nlock your vehicle, some
convenience functions, such as the master key remote function or
powe r seat adjustme nt, may not be ava ilable. The convenience
functions will be available again when you turn on the ignition and
start the engine .
Wint er op erati on
Duri ng the winter mont hs, batte ry capacity tends to decrease as
temperatures drop . This is because more power is also consumed
whi le star tin g, and the headlights, rear window defogger, etc ., are
used more often.
Avoid unnecessary power consumption, particular ly in city traffic or
when trave li n g o nly short dis tances . Let your authorized Audi dea ler
check the capacity of the vehicle battery before winter sets in
~ page 344. A we ll cha rged battery w ill not only preven t starting
problems when the weather is cold, but will also last longer . ..,_

make, there will be six to eight of them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other symbols)
indicate the positions of the tread wear indicators. Worn tires must
be replaced. Different figures may apply in other countries=>& .
Tire pressure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out. For this reason, tire pressure must be checked
at least once a month =>
page 353.
Driving style
Driving fast around curves, heavy acceleration and hard braking
increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rotated according to the
tire manufacturer's suggested tire rotation intervals. Please
remember the following:
• Tire rotation intervals may differ from the vehicle service inter
vals outlined in your Warranty
& Maintenance booklet.
• The longer one tire is used in one location on the vehicle , the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer's suggested tire rotation intervals .
• Vehicles with front-wheel drive experience more tread wear on
the front wheels compared to all-wheel drive (quattro ®l.
• Please rotate tires as shown =>
page 357, fig. 294.
• Extra care must be taken when rotating direction-specific tires
=>
page 379.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa
tions during everyday driving can cause them to become unbal
anced, resulting in vibrations you can usually feel through the
steering wheel. Unbalanced
wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause excessive tire wear , impairing
the safety of the vehicle. If tires show excessive wear, have the
wheel alignment checked by an authorized Audi dealer or qualified
workshop.
All Wheel Drive
Vehicles with quattro® must always have tires of the same size,
construction and tread type. For details see=>
page 294.
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• 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 speeds .
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •
