Braking
General information
What affects braking efficiency?
Operating condi tions and d riv ing hab it s
The brakes on today's automobi les are sti ll
subject to wear, depending largely on operat­
ing conditions and driving habits
c:> A . 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
i zed Audi dealer more often than specified in
the
Warr ant y & Maint enan ce bookle t. Failure
to have your b rake pads inspected can res ult
i n red uced brake performance.
On steep slopes, you should use the brak ing
effect of the engine. This way, you prevent un­
necessa ry wea r on the brake system.
If you
must use yo ur brakes, do not ho ld the brakes
down continuously. Pump the brakes at inter ­
va ls.
Moistu re or road salt
Unde r ce rtain conditions, for example, when
driving through wate r or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced d ue to moisture (or in
freezing conditions ice) on the brake pads . A
few careful brake app lications should dry
off
the brake pads or remove any ice coatings.
When you are driving at higher speeds with
the windshield wipers on, the brake pads will
briefly touch the brake discs in regular inter­
vals so as to improve reaction t ime when brak­
ing on wet surfaces . You the driver w ill not no­
tice anything .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the brakes are not used . Here too,
you should clean
off accumulated salt coat ing
from b rake discs and pads with a few careful
applications of the brake

the d iscs if the car is not driven regu larly or
only for short trips with litt le use of the
brakes.
If the brakes a re not used frequently, o r if cor­
rosion 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 high
speed

Fault s in the brak e syste m
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
circuits may have fai led ¢

Low brake fluid lev el
Malfunctions can occu r in the bra ke system if
the brake fluid level is too low. The brake flu id
level is monitored elect ronica lly.
Brake booster
The brake booster works with vacuum pres­
su re which is created only whe n the engine is
runn ing ¢,&. .
Brake lining we ar s tatus
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the wheel may be removed fo r thi s in­
spection ¢
page 263, Changing a wheel.
_& WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit .
Other road users must not be put at risk -
you may ca use an accident!
- Before descending a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride
the brakes or hold the pedal down too long or too often . Th is could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing your
foot on the pedal when you do not intend
to b rake. This may cause the brakes to
•
•

192 Intelligent technology
overheat, premature wear and increased
stopp ing distance.
- Under certain climatic and operating
condit ions such as passing through wa­
ter, driving in heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice ca n
accumulate on the brake pads, linings ,
discs and d rums . Carefully apply brakes
for a test . B rakes wi ll dry a nd ice coat­
ings will be cleaned off after a few c are­
f ul brake app lications .
- Dr iv ing fo r an ex tende d pe riod of time on
salt-covere d roads w ithout us ing yo ur
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
bra ke discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­ ed. Otherwise the brake system could
over heat reducing the effectiveness of
the ent ire brake system .
- Failure of one brake c ircuit will impair
the braking capability res ulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to t he near­
est Aud i dea le r o r q ualified w ork sho p.
- Never let the vehicle ro ll to a stop w ith
the e ngine shu t off.
- If the brake booster is not working, the
brake pedal must be p ressed conside ra­
bly harder to make up for the la ck of
booster assistance.

environment
The first 1,000 miles
(1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometers ):
.,. Do not use full throttle.
... Do not d rive at engine speeds that are more
than 2/3 of the max imum permitted RPM.
... Avoid high engine speeds.
From 600 to 1,000 mile s (1 ,000 to
1,500 kilometers):
... Speeds can gradually be increased to the
max imum pe rm iss ible road or eng ine speed .
During and after break-in period
.,. Do not rev the eng ine up to high speeds
when it is cold. Th is app lies whether the
transm ission is in N (Neutra l) or in gear.
After the break-in period
... Do not exceed maximum engine speed un­
der any circumstances.
.,. Upshift into the next hig her gear
before
reaching the red area at the end of the tach­
ometer scale
c:> page 10.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving parts have been broken
in . How well this break- in process is do ne de­
pends to a conside rable extent on th e way the
ve hicl e is driven during the first 1,0 00 miles
(1, 500 k ilome ters).
0 Note
E xtremely high engi ne speeds are auto­
mat ica lly reduced. However, these rpm
lim its are progr amme d for an engine well
r u n- in, not a new engine .
{® For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds - upshifting ear ly saves fuel,
reduces no ise and protects the environ­
ment.
, New tires
If your vehicle is runni ng on new tires, drive
part icularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
A WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be s ure to remember
this dur ing the fi rst 350 mi les ( 500 kilo ­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
braking .
New brake pads
Remember that new brake pads do not have a
full bra king effect dur ing the fi rst 250 m iles
(400 kilomete rs) afte r they a re insta lled.
New brake pads have to be "burnished in" be­
fo re t hey have optima l grab
c:> A .
During the break- in period, you should avoid
putting severe loads on the brakes. Severe
l oads include, for example, sudden hard brak­
i ng, in particular at very high speeds or, for
example, on mounta in passes .
A WARNING
New b rake pa ds don't have t he bes t stop­
pi ng power and m us t be "broke n-in " dur­
i ng the in itial 1 00 to 150 mi les (15 0 to
2 00 k ilometers) of no rma l city driving . You
can compensate for this by pressing th e
br ake peda l mo re f irm ly . This also applies
l ater when new pads are installed.

Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
T his is especially true for vehicles with low­
slung chassis (sports chassis) * and fully load­
ed veh icles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any h igher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
- Vehicle components such as the eng ine,
transmission, suspension or e lectrical
system can be severely damaged by driv­ ing through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not s top the veh icle, drive in reverse
or switc h the engine off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh sa lt water because
-
~ it can ca use corrosion. ,....,

Warming up and
cooling down
By carefully warming up and cooling down
your vehicle, you can help ensure that it is not
overstressed unnecessar ily during sporty dr iv­
ing.
When warming up, the vehicle is dr iven at a
maximum engine speed of 6000 RPM in order
to raise the engine o il temperature to a mini­
mum of 140
°F (60 °() . The t ires a lso on ly
reach the ir full road holdi ng capabi lity on ce
they have warmed up.
The cooli ng fan can cont inue to run in your ve­
hicle after the engine is switched off . Howev­
er, driving the veh icle to coo l it down is pa rti c­
ul arly important. Dur ing spo rty driving , the
engine and b rakes, the exhaust system, and
the transmission a ll become extremely hot.
Before you park the vehicle, you should drive
it for a few miles/kilometers at light load in
the low rpm range to allow it to cool down .
Catalytic converter
App lies to vehicles: wi th gaso line e ngi ne
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
"' Always use lead-free gasoline c:> page 206,
Fuel supply .
"' Never run the tank down all the way to emp­
ty.
"' Never put too much mo to r o il in yo ur eng ine
c:> page 21 S, Adding engine oil "t:::r..
"' Never try to push -or tow -start you r vehicle .
T he catalytic co nve rter is an efficient "clean ­
u p" dev ice bui lt into t he exhaus t system of
the ve hicle . The cata lytic converter bu rns
many of the pollutants in the exha ust gas be ­
fore they are re leased into the atmosphere.
T he exclus ive use of unleaded fuel is c ritical ly
i mportant for the life of the catalyt ic convert -
er and proper functioning of the engine .

220 Checking and filling
Brake fluid
Checking brake fluid level
Fig . 192 Engine compar tment: 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 211.
,.. Read the brake fluid level from the brake
fluid reservoir¢
fig . 192, ¢ page 213,
fig. 188 .
The brake fluid level must be be­
tween the "MIN" and "MAX" markings.
The location of the brake flu id reservoir can be
seen in the engine compartment illust rat ion
¢ page 213.
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 be­
low the "MIN" mark, the brake warning/indi­
cator light . (U.S. models)/ . (Canadian
models) will come on ¢
page 14. Do not con­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized A udi dealer or other quali­
fied facility and the cause corrected.
If the
brake fluid level is too low, the brake warning/
indic ator light will 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
t he 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 flu id will also decrease conside rably 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 "FMVSS 116 DOT 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 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 f luid is also indicated 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 resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .
