Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
Brake fluid absorbs moisture from the ai r. 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 wil l also
decrease considerably and decrease braking performance .
Therefore, the brake fluid must be changed
e ver y two years. Always
use new brake fluid which conforms to Federa l Motor Vehicle Stan ­
dard "FMVSS 116 DOT 4" .
The brake fluid reservoir can be difficu lt to reach , therefore, we
recommend that you have the brake fluid changed by your autho­
rized
Audi d ealer. Your dealer has the correct tools, the right brake
fluid and the know-how to do this for you.
& WARNING
• Bra ke fluid i s poisonous . It mu st be stored on ly in the close d
ori ginal container out of the rea ch of children!
• Bra ke fa ilure can result from old or inappropri ate brake fluid .
Observe the se pre caution s:
- Use o nly brake fluid that meets SAE spe cifi ca tion
J 170 3 and
c onform s to Fed era l Moto r Vehic le Sta nda rd 116 . Always c heck
w ith your authori zed Audi de aler to m ake sure you are using
the correct brake fluid. The corr ect type of brake fluid i s als o
indi cated o n the br ake fl uid reser vo ir.
- The br ake flu id mu st be ne w. Hea vy use of the brake s can
c au se a vap or lo ck if the bra ke fluid i s left in the system too
long. Thi s can seriou sly affect the efficienc y of the brake s as
we ll as your safet y. Thi s co uld re su lt in an acci dent .
0 Note
Brake fluid wi ll damage the paint of your vehicle .
<£' For the sake of the environment
Because o f the problem of prope r disposal of brake flu id as we ll as
the special tools required and the necessary expertise, we recom ­
mend that you have the brake fluid changed by your authorized Audi
dea ler. •

Di sco nnecting the batt ery
Some vehic le 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
vehicle el ectrical system if absolutely necessary.
Vehic les not driven f or lo ng peri o ds a nd sho rt -di stan ce
o pera tion
The battery can a lso become discharged with the veh ic le stationary
by id ling current consumers . When the vehic le is sta tionary
(planned event) during the
cold t ime of the year, you should remove
the battery and store it in a nonfreezing area . This way you prevent
that the battery "freezes" and thereby is destroyed . During the
w arm er time of the year it is sufficient to disconnect the negative
terminal from the battery . Occasionally charge even a disconnected
battery .
Wint er opera ti on
During the winter months, battery capacity tends to decrease as
tempera tures drop . This is because more power is a lso consumed
while starting, and the headlights, rear window defogger, etc., are
used more often .
Avoid unnecessary power consumption, particularly in city traffic or
when trave ling only short distances. Let your authorized Audi dea ler
check the capacity of the vehicle battery before w inter sets in
=>
page 239. A well charged battery will not only prevent starting
problems when the weather is cold, but w ill also last longer.
Replacin g battery
The new battery m ust h ave the same capacity , voltage (12 volts),
amperage, construction and p lug sea ling, as the orig inal battery.
Specif ications are listed on the battery housing. Batteries special ly
developed by Audi fulfil l the maintenance, output, and safety
requirements.
When instal ling the battery, make sure the ignition and all electrica l
consumers are switched off=>
(D.
We recommend that you use maintenance -free or c y c le -resis­
tant /leak -proof
batte ries according to the sta ndards TL 825 06 (from
December 1997) and VW 7 50 73 (from August 2001).
(D Note
• All work on the battery requires technical knowledge . Please
contact an Audi dealership or another authorized fac ility for ques ­
tions about the battery- danger of acid burns and exp losion hazard!
• The battery must not be opened! Do not try to change the
battery's liquid level, otherwise detonating gas wil l escape from the
bat tery -explosion hazard!
• The AGM battery in the luggage compartment cannot leak,
because the electrolyte for this battery is abso rbed in to a special
glass mat . This leak-proof battery must not be replace with a
conventiona l battery.
• Make sure the ventilation hose on the side of the battery is
connected, otherwise fumes or battery acid can leak out.
• Battery holder and terminals always have to be secured correctly .
• Before all work on the ba ttery follow the
warning s below=> & in
"Working on the battery" on
page 238.
Because of the problem of proper disposal of a battery, we recom­
mend your authorized Audi deale r change the battery for you .
Batteries contain sulfuric acid and lead and must always be
disposed of properly in comp liance with a ll environmental regula ­
tions . D isposing of vehicle batteries improperly is very dangerous to
the environment. Make sure that the removed batte ry cannot over ­
balance , otherwise sulfuric acid might escape! •

• Never charge a frozen battery . It may explode because of gas
trapped in the ice. Allow a frozen battery to thaw out first .
• Do not reuse batteries which were frozen . The battery housing
may have cracked and weakened when the battery froze .
• Charge the battery in a well ventilated area . Keep away from
open flame or electrical spark . Do not smoke . Hydrogen gas gener ­
ated by the battery is explosive .
• To reduce the danger of explosion , never connect or disconnect
charger cables wh ile the charger is operating .
• Fast charging a battery is dangerous and should only be
attempted by a competent technician with the proper equipment .
• Battery acid that may spill during charging should be washed
off with a solution of warm water and baking soda to neutralize
the acid .
0 Note
• Nev e r use a fast charger as a booster to start the engine. This will
seriously damage sensitive electronic components, such as control
units, re lays, radio, etc ., as wel l as the battery charger .
• T he vehicle may be optio nally equi ppe d wi th a ge l batt ery , w hich

& WARNING
• Using incorrect or unmatched tires and / or wheels or improper
tire and wheel combinations can lead to loss of control , collision
and serious personal injury .
• Always use tires , rims and wheel bolts that meet the specifica ­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
espe cially 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.
& WARNING (continued )
• All four wheels must be fitted with radial tires of the same type,
size {rolling circumference ) and the same tread pattern. Driving
with different tires reduces vehicle handling and can lead to a loss
of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build-up , sudden tire failure ,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated and
not over or underinflated.
• For technical reasons it is not always possible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels , make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be used on vehicles that were equipped
with them at the factory . The vehicle must have a chassis designed
for run flat tires and a factory-installed tire pressure monitoring
system* that indicates a loss of tire pressure . Incorrect use of run
flat tires can lead to vehicle damage or accidents . Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equipped with run flat tires . If run flat tires are used , they must
be installed on all four wheels . Mi xing tire types is not permitted. _,.
