Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first ¢
.1:,.. The break-in pe­
riod can be considerably longe r fo r vehicles with
192
ceramic brake rotors*. You can compensate for
this slightly reduced braking power by push ing
harder on the brake pedal. Avoid heavy braking
lo ads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub ­
j ect to wear, depending large ly on operating con­
ditions and driving habits¢,& . On vehicles that
are either driven mostly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Audi dealer more of ­
ten than specified in the
Warranty & Mainte­
nance booklet .
Failure to have your brake pads
inspected can result in reduced brake perform­
ance.
On steep slopes, you should use the brak ing ef­
fect of the engine. T his way, you prevent unnec­
essary wea r on the brake system. If you mus t use
your brakes, do not hold the brakes down contin-
u ously. Pump th e brakes at intervals. ..,.

Operating noi se
Noises may occur when braki ng depend ing on the
speed, braking force and outside cond itions s uch
as temperature and humidity.
Due to the na ture of t he mate ria ls used in ce ram­
ic bra ke rotors*, noises m ay become mo re appa­
ren t at low speeds.
Effect of wat er and road salt
In ce rtain situat ions, for example after driving
through water, in heavy ra in, afte r ove rnig ht con­
densat ion or after washing your car, the braking
effe ct can be red uced by moisture or ice on the
b rake rotors and brake pads. The brakes must be
dried first w ith a few careful brake applications .
At highe r speeds and with t he windsh ie ld wipers
turned o n, the bra ke pads p ress against the bra ke
rotors for a short amount of time . This occ urs at
regular intervals without the driver noticing and
provides for better bra ke response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered road
and the brakes are not used. L ikewise, you clean
off accumu lated salt coat ing from brake discs
and pads with a few cautious applications of the
brake
c::> ,& .
Due to their sur face characteristics, ceramic
brake rotors* absorb mo isture in such condit ions.
This can cause a temporary reduction in braking
force compared to dry brakes. You can compen­
sate for this by pressing the brake peda l harder.
Cor rosion
There may be a tendency for dirt to b uild up on
the brake pads and corros ion to form on the discs
if the car is not driven regularly or only for short
tr ips with little use of the brakes.
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is adv isable to
clean off the pads and discs by brak ing firmly a
few t imes from a moderately high speed
c::> ,& .
Sma rt Technology
Faults in the brake system
If you s hou ld notice a sudden increase in br ake
peda l travel, then one of the two bra ke circu its
may have fai led
c::> ,& .
Low brake fluid level
Malfunctions ca n occu r in the brake system if the
brake fluid level is too low . T he brake flu id leve l
is monitored elect ronically.
Brake boost er
The brake booster works w ith vacuum pressure
wh ich is created only when the engine is runn ing
c::> ,& .
Brake lining wear status
Brake lining wear may be checked by visua l in­
spect ion of the cond ition of the brake pads
t hr ough the openings in the wheel. If necessary,
the wheel may be removed for t his inspection
c::> page 259, Replacing wheels .
.8_ WARNING
-New b rake p ads don't h ave the bes t stop­
p ing power an d must be "broken-in" during
the initial 250 miles (400 km) . The break-in
pe riod can be considerably longer for
veh icles with ceramic brake rotors*. You can
compensate for this by pressing the brake
pedal more firmly. This also applies late r
when new pads are installed.
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system only i f road co ndit ions pe rmit . Other road
users m ust not be put at r is k -you may
cause an ac cident!
- Before descending a steep g rade, reduce
speed and sh ift transmission into a lower
gear o r lower dr iving range. Do not r ide the
b ra kes or hold the pe dal down too long or
too often. This cou ld cause the b rakes to ge t
hot and dimin ish b raking effic iency .
- Do not " ride the bra kes" by rest ing you r foot
on the pedal when you do no t intend to
brake. This may cause the brakes to over­
heat, premature wear and increased stop­
p ing distance.
193

Smart Techn olo gy
- Under certain climatic and operating condi­
tions such as passing through water, driving
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced . In w inter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fully apply brakes fo r a tes t. Brakes w ill dry
and ice coatings wi ll be cleaned off after a
few careful brake applications .
- Driving for an extended pe riod of time on
salt-covered roads witho ut using your
brakes can also affect bra king efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few carefu l
brake applications.
- If you damage the front spoiler, or if you in­
stall a different spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem.
- Failure of one brake circuit will impair the
braking capability result ing in an increased
stopp ing distance. Avoid driving the vehicle
and have it towed to the nea rest Aud i dealer
or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considerably
harder to make up for the lac k of booster
assistance.

Driving through water on
roads
Note the following to avoid vehicle damage when
driving through water, for example on flooded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water, mud, slush, etc.,
the brakes may be slow to take effect because
of wet brake rotors and pads . Dry the brakes
first by brak ing carefully to restore the full
brak ing effect.
([) Note
-Vehicle components such as the engine,
transm ission, suspension or electrical sys ­
tem can be severely damaged by driving
th rough water.
- Always switch off the Sta rt-Stop-System*
whe n driving through water¢
page 85 .
(D Tips
-Check the depth of the water before driving
through it.
- Do not stop the veh icle, dr ive in reverse or
switch the eng ine off when dr iving through
wa ter .
- Keep in mind that oncoming ve hicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
th rough safely.
- Avo id driving through salt water because it
can cause corrosion.
Driving and the envir onment
Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
nois e levels .
Fuel economy, e nv ir onmental impact, and wear
o n your eng ine, brakes and tires large ly depend
on three factors:
- your personal driving style
- operat ing cond itions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percent. Th is section will
give you some tips on how you can help the envi­
ronment and your pocketbook .
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
r oad, which w ill vary depending upon vehicle
l oad and speed, road and weather conditions,
trip length , etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
.,. Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are acceler­ at ing . If you anticipate what is going to happen
next, you w ill need to brake less and, thus, accel­
erate less. Let the vehicle coast whenever possi­
ble - for example when you see that the next traf­
fic lig ht is red.

Checking and Filling
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick
glance.
Fig. 202 Eng ine compartment: cove r o n th e brake flu id
r eservoi r
Before you check anything in the engine compart­
ment,
always re ad a nd hee d all W ARNING S
¢ A in Working in the engine compartment on
page 220.
., Read the brake fluid level from the brake fluid
reservoir
<=> fig . 202, ¢page 222. The brake flu ­
id level must be between the "MIN" and "MAX"
mark ings.
The location of the brake fluid reservoir can be seen in the engine compartment illustration
¢ page 222.
The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for alarm .
If the brake fluid level falls
considerably below
the ' 'MIN" mark, the brake warning/indicator
light
1111 (U.S. models)/ . (Canadian models)
will come on¢
page 14 . Do not continue to oper­
ate the vehicle . The complete brake system
should be thoroughly checked by an authorized
Aud i dealer or other q ualified facili ty and the
cause corrected.
If the brake f luid level is too
low, the brake warning/indicator light will i llumi ­
nate. Contact an authorized Audi dealer
immedi­
at ely.
230
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­ rosion in the brake system may result after ape­
riod of time . The boiling po int of the brake fluid
will a lso decrease considerably and decrease
braking performance.
Therefore , the brake fluid must be changed
eve ry
two y ears . Always use new brake fluid which con­
forms to Feder-al Motor Vehicle Standard "FMVSS 116 DO T 4".
The brake fluid reservoir can be difficult to reach ,
therefore, we recommend that you have the brake fluid changed by your author ized
Audi
d ea ler . Your dealer has the correct tools, the
right brake fluid and the know -how to do this for
you.
A WARNING
- Brake fluid is po isonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake fai lure can result from o ld or inappro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­ ficat ion
J 1703 and conforms to Federal
Motor Ve hicle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake f luid .
The correct type of brake f luid is also indi­
cated 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 efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi-
cle .
