2008 AUDI TT ROADSTER brake pads

Driver information system
[ i] Tips
• The engine oil pressure symbol 9:::r. is not an indicator for a low
engine oil level. Do not rely on it. Instead, check the oil level in your
engine at regular intervals, preferably each time you refuel, and
always before going on a long trip.
• The yellow oil level warning indication · requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning symbol
9:::r. starts to flash before you respond to the
low oil level warning . By then, your engine may already have
suffered serious damage. •

to automatic mode .
& WARNING
Driving at higher speeds witho ut the re ar spoiler deployed can
impair handling characteri stics, making the vehicle harder to
c ontrol.
• Always make sure that the spoiler i s deployed when driving at
speeds over 85 mph (140 k m/h). If the rear spoiler warning /ind i­
c ator light in the in strument clu ster come s on , the rear spoiler
may not have deployed .
• Never drive at speed s higher than 85 mph (140 km /h ) if the
spoiler is not deployed . Have the spoiler inspe cted as soon as
po ssible by an authorized Audi dealer or qualified workshop.
• Always obey speed limits and other traff ic law s.
& WARNING
Improper operation of the rear spoiler can cause crushing injuries.
• Always make su re that nobody , especially children , is in the
way when the rear spoiler is deployed or retracted.
0 Note
Never push the vehicle or a pply force to the rear spoi ler -it cou ld be
damaged .
[ i ] Tips
Clean the spoi ler compartment every 2 to 3 months . The spoiler
compa rtment must always be free of ice, snow, leaves or other
debris. •
Braking
General "nformation
What aff ects braking effi cie ncy?
Operating condition s and driving habits
The brakes on today's automob iles a re sti ll sub ject to wea r,
depending large ly o n operati ng co nditions and driving habits~&.
On vehicles which are driven mostly in stop -and -go city traffic or
whic h are driven hard, the brake pa ds shou ld be checked by your
authorized Audi dea ler more often than specified in the
Mainte ­
nance
& Warranty booklet.
On steep slopes, you should use the braking effect of the en gine.
Th is way, you prevent u nneces sary wea r on the brake syste m. If you
must use your brakes, do not ho ld the brakes down continuous ly.
P ump the brakes at interva ls.
Moisture or road salt
U nde r certain co nditi ons, for example, when driving th rough water
or v ery heavy rain, or eve n after washing your vehicle, the braking
effec t can be red uced d ue to mo isture (o r in freezing c onditions ice)
o n the brake pads . A few cautious brake appl ica tions should dry off
the brake pads or remove any ice coat ings.
T he effe ctiveness of the brakes can be reduced when the ve hicle is
driven on a sa lt -covered road and the brakes are not used. Li kewise,
you clean off accu mulated sa lt co atin g fr om bra ke discs a nd pads
with a few cautious applications of the brake~&.
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corr osi on to for m on the d iscs if the ca r is no t driven regu lar ly or
only for short trips with litt le use of the brakes .
I f the b ra kes a re not used frequently, or if co rros ion ha s formed on
the d iscs, it is adv isable to clean off the pads a nd discs by braking
firm ly a few times from a moderately high speed~& . .,_

Faults in the brake syst em
If you shou ld notice a sudden i ncrease in brake pedal travel, then
one of the two brake circuits may have failed=>
& -
Low brake fluid level
Ma lfunctions can occur in the brake system if the brake fluid leve l is
t oo low. The brake fluid level is moni tored e lect ronica lly .
Brake pow er assist unit
The brake p ow er assist un it increas es th e pressure that you
generate with the brake peda l. It works only when the engine is
running.
& WARNING
• You should perform braking maneuver s for the purpose of
c leaning the brake system only if road conditions permit . Other
road users must not be put at ri sk -you may cause an accident!
• Before des cending a steep grade , redu ce speed and sh ift trans­
mi ssion into a lower gear or lower driving position . Do not ride the
br akes or hold the pedal down too long or too often . This could
cause the brakes to get hot and diminish braking efficiency .
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake . Thi s may cause the brakes to overheat,
premature we ar and increased stopping distan ce .
• Under certain cl imatic and operating condit ions such as
pas sing through water , driv ing in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter ,
ice can ac cumulate on the brake pads , linings , discs and drums .
Cautiously apply brakes for a te st. Brakes will dry and ice coatings
will be cleaned off after a few cautious brake appli cations .
• Driving for an extended period of time on salt -covered road s
without using your brakes can also affect brak ing effic iency . Clean
off accumulated salt coating from brake discs and pads with a few
c autiou s brake applications .

& W
ARNING (continued )
• If you damage the front spo iler , or if you install a different
s poiler , be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat redu cing the effective­
ness of the entire br ake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increa sed stopping distance. Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop.
• Never let the veh icle roll to a stop with the engine shut off .
• If the b rake booster is not working , for e xample when towing
your vehicle, or because the brake booster has somehow been
damaged , the brake pedal must be pre ssed considerably harder to
make up for the lack of booster assistance . •
Anti- lock brake system (ABS)
ABS p revents the wheel s from loc king unde r br ak ing.
The anti -lock brake sys te m (ABS) makes a major contri but ion to
i ncreasing act ive d riv in g sa fety . You should not expect that brakin g
distances wi ll be
shortened unde r all c ircums tances wi th ABS.
B rak in g distance may even become somewhat
longer , for e xa m ple ,
on gravel or in new snow on s lippery ground, even if you are driving
carefully and slowly.
ABS operation
W hen a veh icle speed o f about 10 mph (20 km/ h) is reac hed , an au to ­
matic test sequence is run. Some noise from the pum p may be
audible.
I f the speed of a wheel s lows down too much re lative to vehicle
speed and i t starts to lock, br ake pressu re to th is whee l is reduce d.

New brake pads
Remember that new brake pads do not have a full braking
effec t during the first 250 miles (400 kilometres) after they
are installed.
New brake pads have to be "burnished in" before they have optima l
grab=> &.
During the break -in period, you should avoid putting severe loads
on the brakes. Severe loads include, for example, sudden hard
braking, in particular at very high speeds or, for example, on moun ­
tain passes.

Catalytic converter
It is very important that your emission control system
(catalytic converter) is fu nctioning properly to ensure that
y o ur vehicle is running in an environmentally s ound
manner.
- Always use lead-free gasoline~ page 214, "Fuel supply".
- Never run the tank down a ll the way to empty.
- Never put too much motor o il in your engine~

- Neve r try to push -or tow -s tart your ve hicle.
Controls and equip­
ment Safety first Vehicle operation
Dri
ving and environm ent
The catalytic converter is an efficient "clean-up" device built into the
exhaust system of the vehicle . The cataly tic converter burns many
of the pollutants in the exhaust gas before they are re leased into the
atmosphere.
The exclusive use of un leaded fuel is critica lly important for the l ife
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or oper ate th e ve hi cle in are a s whe re the hot
exha ust sys te m may c ome in conta ct wi th dr y grass, bru sh , fu el
s pill or other mat eri al which can cau se a fi re.
• Do not app ly a dditi onal u nder co at ing or ru stpr oofing on or
near the exhau st m anifold , exh au st pipe s, cata ly tic convert er or
he at shi elds. During dri ving, the s ubstance use d f or und ercoa ting
c ould ov erheat an d ca u se a fire.
0 Note
• Be aware that just one tank fi lling with
le ad ed fuel wi ll a lready
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level =>
page 225.
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire . Unburned fuel could a lso get into the exhaust
system and this could cause the catalytic converter to overheat .
• Do not turn off the igni tion wh ile the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fue l can reach the cata lytic converter. This could resu lt
in overheating of the converter, requiring its replacement .
• To assure efficient operation of the Emiss ion Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Maintenance & Warranty
booklet.

& WARNING (continued)
• The auxiliary electric fan is temperature controlled and can
switch on suddenly even when the engine is not running.
• The auxiliary radiator fan switches on automatically when the
engine coolant reaches a certain temperature and will continue to
run until the coolant temperature drops. •
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick glance.
Fig. 155 Engine
compartment: brake
fluid reservoir
Before you check anything in the engine compartment,
always read and heed all WARNINGS =>
& in "Working in
the engine compartment" on
page 220.
- Read the brake fluid level from the brake fluid reservoir
~ fig. 155. The brake fluid level must be between the
"MIN" and "MAX" markings.
The brake fluid reservoir is located behind the rear partition of the
engine compartment on the left side~
page 221 .
The fluid level may drop slightly after some time due to the auto­
matic 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 (U .S. models:
BRAKE , Canadian models:
ill) will come on~ page 20 and~ page 32. Do not continue to
operate the vehicle . The complete brake system should be thor­
oughly checked by an authorized Audi dealer or other qualified
facility and the cause corrected. If the brake fluid level is too low, the
brake warning/indicator light will illuminate. Contact an authorized
Audi dealer
immediately .•
Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
Brake fluid absorbs moisture from the air. 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 will als o
decrease considerably and decrease braking performance.
Therefore, the brake fluid must be changed
every two years. Always
use new brake fluid which conforms to Federal Motor Vehicle Stan ­
dard "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 autho­
rized
Audi dealer . Your dealer has the correct tools, the right brake
fluid and the know -how to do this for you.
& WARNING
• Brake fluid is poisonous. It must be stored only in the closed
original container out of the reach of children!
• Brake failure can result from old or inappropriate brake fluid.
Observe these precautions : .,,_
