190 Intelligent technology
Operating conditions and d riving hab it s
The brakes on today 's automob iles are st ill
subject to wear, depending largely on operat ­
ing conditions and driving habits
c::> ,& . On
vehicles that are either driven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your author­
ized Audi dealer more often than specified in
the
W arranty & M ainte nance booklet . Failure
to have your brake pads inspected can result
in reduced b rake pe rformance.
On steep slopes, you should use the brak ing
effect of the eng ine . This way, you prevent un ­
necessa ry wear on the brake system. If you
must use you r brakes, do not hold the brakes
down continuously . P u mp the b rakes at inter­
va ls.
Operating nois e
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity .
Effect of w ater and ro ad sa lt
In certain situat ions, for example after driving
through wate r, in heavy ra in, after overn ight
condensation or after washing your car, the brak ing effect can be reduced by moistu re or
i ce on the bra ke roto rs and b rake pads . The
b rakes must be dried fi rst with a few ca ref ul
brake app lications .
At h igher speeds and with the w indshie ld w ip­
e rs turned on, the brake pads press agains t
the bra ke rotors for a short amount of time.
This occurs a t regular intervals without the
driver noticing and provides for better brake response time under wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the brakes are not used. Likewise,
you clean off accumulated sa lt coating from
brake discs and pads with a few caut ious ap ­
plications of the brake
c::> ,& .
Cor rosion
There may be a tendency for dirt to bui ld up
on the brake pads and corrosion to form on the d
iscs if the car is not driven regu larly or
o n Ly for short trips with litt le use of the
brakes.
If t he brakes a re not used frequently, o r if cor­
r os ion has formed on the discs, it is adv isable
to clean off the pads and discs by braking
firmly a few times from a moderately h igh
speed
c::> .&. .
Fault s in the brak e syst em
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
circuits may have fai led
c::> .& .
Low br ake fluid lev el
Malfunctions ca n occu r in the b ra ke system if
t h e b rake fluid level is too low. The brake flu id
l evel is monitored electronica lly.
Brake booster
The brake booster inc reases the pressure that
you generate with the b rake peda l. It works
o n ly when the engine is runn ing
.c::> .&
Brake lining wear status
Brake lining wear may be checked by visual in­
spect io n of the condition of the brake pads
th rough the open ings in the wheel. If neces­
sary, the wheel may be removed fo r thi s i n­
spe ct ion
c::> page 255, Changing a wheel.
.&, WARNING
- New b rake pads don' t have the bes t stop­
ping power and m ust be "bro ken -in" dur ­
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal c ity driving.
You can compensate for this by pressing the brake pedal more firmly. Th is also
applies later when new pads are instal­
led.
- You shou ld perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Othe r road use rs must no t be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride
~

-To reduce the r isk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before ca re­
fully opening the hood .
- Keep children away from the engine com ­
partment.
- Never spill flu ids on hot engine compo­
nents. They can cause a fire .
- Never touch the radiator fan. The aux ili­
ary e lectr ic fan is temperature controlled
and can switch on suddenly .
- Never open the coolant reservoir cap
when the eng ine is still warm . The cool­
ant system is pressur ized and hot coo l­
ant could spray out.
- Protect your face, hands and arm from
steam or hot eng ine coolant by placing a
thic k rag over the cap when you open the
coolant reservoir.
- Do not remove the engine cover under
any c ircumstances. Th is increases the
risk of bu rns.
- If wo rk on the fuel system or the electri­
cal sys tem is ne cessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames . Fluids in the engine com­
partment co uld start a fire.
- Keep an approved fire extinguisher im­
mediately ava ilable.
- To avoid electrical s hock and persona l in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repa ir
with the engine running:
- Fir st, fully apply the parking brake,
move se lector lever of a utomatic trans-
Checkin g and fillin g 215
mission to "P" (Park); put manual
transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewe lry, or long hair from get­
ting caught in the radiator fan, V-be lts
or other moving parts, or from contact­ i ng hot parts . Tie back hair before
starting, and do not wear clothing that
will hang o r droop into the engine .
- Minimize exposure to emission and
chemical hazards~&. .
A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its const ituents,
a nd certain vehicle components contain
or emit chemicals known to the State of
Ca lifornia to cause cance r and birth de­
fects and reproductive harm. In addition, certain fl uids contained in veh icles and

Q) Note
When adding f lu ids, always make sure that
they are poured into the proper conta iner
or f iller opening, otherwise serious dam­
age to vehicle systems w ill occur .
@ For the sake of the environment
