Braking
General "nformation
W hat 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 that are either driv en mostly in stop -and -go city traffic
or are driven hard, the brake pads shou ld be c hecked by you r au tho ­
ri ze d Audi dea ler mor e often than sp ecified in the
Warranty & Main ­
tenance booklet.
Fai lure to have your brake pads inspected can
resu lt in reduced brake performance.
On s teep sl opes, you should use the braking effec t of the engine .
T his way, you prevent unnecessary wear on the brake sys tem . If you
must use your brakes, do not hold the brakes down continuous ly.
P ump t he b rakes a t interva ls.
Moi sture or road salt
Under certa in conditions, for example , when driving through water
or
ve ry heavy rai n, o r even afte r washing you r ve hicle, the brak ing
e ff ect can be reduced due to moisture (or in freezing cond it io ns ice)
on the brake pads . A few cautious brake applications should dry off
the brake pads or remove any ice coat ings.
T he effectiveness of the brakes can be reduced when the vehic le is
driven on a sa lt-c o ve re d r oad and the brake s are not used . Likew ise,
you clean off accumulated sa lt coat ing from brake discs and pads
wit h a few cau tious applica tions of t he brake ~& .
Corrosion
There may be a tendency for d irt to buil d up o n the b rake pads a nd
corrosion to form on the discs if the car is not driven regular ly or
only for sho rt trips wi th lit t le use of the brakes. ._

If t he brakes ar e not used frequently , or if corrosion has for med on
th e d iscs, i t is adv isa ble to cl ean off the pads a nd disc s by braki ng
firm ly a f ew times from a moderate ly high speed=:> &.

Brake power assist unit
T he bra ke po wer assist unit increas es the pressure that you

& 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 cause an accident!
• Before descending a steep grade , reduce speed and shift trans­
mission into a lower gear or lower driving position . Do not ride the
brakes 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 . This may cause the brakes to overheat ,
premature wear and increased stopping distance .
• Under certain climatic and operating conditions such as
passing through water , driving in heavy rain or after washing the
Controls and equip­ ment Safety first Vehicle operation

& WARNING
(continued )
vehicle, the effectiveness of the brakes can be reduced . In winter ,
ice can accumulate on the brake pads , linings , discs and drums .
Cautiously apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few cautious brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can also affect braking efficiency. Clean off accumulated salt coating from brake discs and pads with a few
cautious brake applications.
• If you damage the front spoiler , or if you install a different
spoiler, be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased 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 brake booster is not working, for example 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 CABS)
ABS preve nts th e wheels from lo cking under br aking.
The anti -loc k brake syste m (ABS) makes a major contribution to

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 211, "Fuel supply".
- Never run the tank down a ll the way to empty.
- Never put too much motor o il in your engine~

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

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 222.
• 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 Warranty

Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick glance.
Fig. 143 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 217.
-Read the brake fluid level from the brake fluid reservoir
=> fig. 143. 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 218.
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:
(Cf))) will come on~ page 19 and~ page 33. 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 also
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.
