• If the .. (USA models )/ ...,. (Canada models ) wa rning light
does not go out , or if it comes on while driving, the ABS system is
not working properly. The vehicle can then be stopped only with
the standard brakes (without ABS ). You will not have the p rotec­
tion ABS provides. Contact your authorized Audi dealer a s soon as
pos sible.
• USA models : If the BRAKE warning light and the M, warning
light come on together, the rear wheels could lock up fir st under
hard braking. Rea r wheel lock-up can cause loss of vehicle cont rol
and an accident . Have your vehicle repaired immediately by your
autho rized Audi dealer or a qualified work shop. Dri ve slowly and
avoid sudden, hard brake applications.
• Canada models: If the brake warning light 0 and the ABS
warning light come on together, the rear wheels could lock up
first under hard braking. Rear wheel lock -up can cause loss of
vehicle control and an accident . Have your vehicle repaired imme­
diately by you r authorized Audi dealer or a qualified wo rkshop.

Applie s to veh icles : wi th Adap tiv e Crui se Con tro l
How does Adaptive Cruise Control work?
Vehicles traveling ahead ore detected with the aid of a
radar sensor.
Fig. 132 Basic prin­
ciple diagram: Radar
sensor measurement
range
Adaptive Cruise Control uses a radar sensor in the front of the vehicle
=>
page 138, fig. 132 . The system has limitations=> page 149.
Things that are not moving in your lane and in your direction of travel
w ill not be detected. The sensor measures the distance to reflective
surfaces that must have a certain size. The system responds only
after the distance measurement has been made . If a measurement is
not possible, the system cannot respond and will not react to a
vehicle or someth ing else up ahead.
Open road
When the road is clear, the Adaptive Cru ise Control works like cruise
control. It maintains a constant target speed specified by the driver .
Driving in traffic
If a slower veh icle driv ing ahead is detected, the Adaptive Cruise
Control decelerates (within the limits of the system)=>
page 148,
"Driver intervention prompt" and => page 149, "System limitations"
to its speed and after adjusting, tries to ma inta in the set distance
from the vehicle ahead. The vehicle may temporarily drive slower
than the set speed whi le adjusting=>
& in "Descr iption" on
page 136.
If the vehicle in front accelerates, Adaptive Cruise Control also accel­
erates up to the speed that you have set.
If the vehicle ahead slows to a stop, ACC w ill slow your vehicle down
and to a complete stop if this is possible within the system's limits
and capabilities . ACC will not make an emergency stop. The text
message
ACC off: manual control! appears in the instrument cluster
display. Once the vehicle stops, you must depress the brake pedal to
prevent the veh icle from moving forward or "creeping". Depressing
the brake pedal turns off ACC. When the vehicle ahead accelerates
you can reactivate ACC =>
page 141, as soon as your vehicle has
reached a speed of 1 mph (2 km/h) .
Situations requiring driver intervention
In some situations you will have to use the footbrake to slow the
vehicle down in order to keep a safe distance from vehicle in front of
you or to avoid a rear-end collision. In this situation, a symbol
appears and a warning tone sounds=>
page 148.
Passing another vehicle
If you move into the passing lane and no vehicle is detected ahead,
the Adaptive Cruise Control accelerates to the speed you have set and
maintains it.
Overriding ACC
You can increase your speed at any time by stepping on the acceler ­
ator pedal. After you release the accelerator pedal, the system
adjusts back down to the speed you previously set.
Reduc ing stopping distance
If the radar sensor detects that the distance to the vehicle ahead is
less than defined minimum distance, the brakes are automatically
prepared for emergency braking by the driver. The brake pads are
moved very close to the brake discs withou t actually bra king the
vehicle. This brake assistant feature reacts more quickly to the driver's braking, and also works when Adaptive Cruise Control is off.
The stopping d istance is reduced as a result of this advance brake .,_

_________________________________________ I_ n_ t_ e_ ll_,igent technology ,__E~-
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR w ill also be out of action.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
To ensure that the ASR works properly, all four whee ls must be fitted
with ident ical tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when th is is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending large ly on operating conditions and driving habits=>& .
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 authorized
Audi dealer more often than specified in the
Warranty & Mainte­
nance booklet.
Failure to have your brake pads inspected can result
in reduced brake pe rformance .
On steep slopes, you should use the brak ing effect of the engine . This
way, you prevent unnecessary wear on the brake system. If you must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when braking depending on the speed , braking
force and outside conditions such as temperature and humidity.
Safety first
Moisture or road salt
If you are driving faster than 31 mph (SO km/h) and the windshield
wipers are on, the brake pads wi ll briefly touch the brake discs in
regular interva ls so as to improve reaction time when braking on wet
surfaces . You, the driver, will not not ice anything.
Under certain cond itions, for example, when driving through wa ter or
very heavy rain, or even after washing yo ur vehicle , the braking effect
can be reduced due to moisture (or in free zing conditions ice) on the
brake pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings .
The effect iveness of the brakes can be reduced when the vehicle is
dr iven on a sa lt-covered road and the brakes are not used. Here too,
you should clean off accumu lated salt coating from brake discs and
pads with a few careful applications of the brake=> & -
Corrosion
There may be a tendency for dirt to build up o n the brake pads and
corrosion to form on the dis cs if the car is no t driven regularly or only
for short trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
the discs, it is advisable to clean off the pads and discs by braking
firmly a few times from a moderately high speed=> &.
Faults in the brake system
If you should notice a sudden increase in brake pedal travel, then one
o f the two brake circuits may have failed==>& .
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low. The brake fluid level is monitored e lectron ically .
Brake lining wear status
Brake lining wear may be checked by visual inspection of the condi­
tion of the brake pads through the openings in the wheel. If neces­
sary, the wheel may be removed for this inspection =>
page 343,
"Changing a wheel". ._.

Intelligent technology
'-----------------------------------------------
in. WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road condition s permit. Other
road u sers must not b e put at r isk - you may cau se an ac cident!
• Before d esc ending a steep gr ade , redu ce speed and shift tran s­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often . This could
cause the brake s to get hot and diminish braking efficiency.
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake. Thi s may caus e the brakes to overheat ,
premature wear and increa sed stopping di stance.
• Under certain climatic and operating conditions such as
pas sing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter,
ice can accumulate on the brake pads , linings , disc s and drums .
Carefully apply brakes for a test. Brake s will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt -cov ered roads
without using your brakes can al so affect braking efficiency. Clean
off accumulated salt coating from brake d iscs and pads with a few
careful brake applications.
• If you damage the front spoiler , 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 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 authorized Audi dealer or
qualified wo rkshop. •
Brake booster
The brake booster adds e xtra brakin g pow er .
The brake booster works with vacuum pressure which is created only
w hen the en gine is ru nning =>& .
in. WARNING
• Never let the vehicle roll to a stop with the engine shut off .
• If the brake booster i s not working , for example when towing
your vehicle , or because the brake booster has somehow been
damaged , the brake pedal must be p ressed considerably harder to
make up for the lack of booster assistan ce.
Functioning of Anti-Lock Brake System
(ABS)
AB S prevents the wheels from locki ng up under braking.
T he ABS co ntribu tes effectively to vehicle co ntrol s ince it prevents t he
w hee ls from
locking when the b rakes are a pplied. This means t hat t he
veh icle rema ins steerable and is less likely to s kid .
W ith ABS you do not need to
pump the brake. Just hold the brake
pedal down .
However, do not expect the ABS to shorten braking distance u nder
oil
circums tances. When driving on grave l or on newly fa llen snow on top
of icy su rfaces, braking dis tance may be even longer, therefore, under
these c irc umstances, it is especially important that you dr ive slowly
and w it h great care .
How the ABS system works
An automatic check is made when a speed of about 12 mph (20 km/h)
is reached . Whe n this happens, a p umping noise can be hea rd. ._

The first 1,000 miles (1,500 km)
and afterwards
New engine
The engine needs to be run-in during the first 1,0 00 miles
(1,50 0 km) .
For the first 600 miles (1,000 kilometers):
- Do not use fu ll thrott le .
- Do not drive at engine speeds that are more than 2/3 of
the maximum permitted RPM .
From 600 to 1,000 miles (1 ,000 to 1 ,500
kilometers):
- Speeds can
gradually be increased to the maxim um
perm iss ible road or engine s peed .
During and after break-in period
- Do no t rev the eng ine up to high speeds when it is co ld.
T h is app lies w hether th e t ransmission is in N ( Neutral) o r

& WARNING
New tires tend to be slippery and must also be "broken -in ". Be
sure to remember this dur ing the first 350 miles (500 kilome ­

Vehicle care Do-it-yourself service Technical data

Driving and environment
New brake pads have to be "burnished in" before they have optimal
grab ~& .
Dur ing the break-in period, you should avoid putting severe loads on
the bra kes. Severe loads incl ude, for example, sudden hard braking,
in part icu lar at very high speeds or, for examp le, on mountain passes .
& WARNING
New brake pads don't have the be st stopping power and must be
" b roken-in " du ring the initial 100 to 150 miles (150 to 200 kilo­
meters ) of normal city driving . You can compensate for this by
pressing the brake pedal more firml y. This also applies later when
new pad s are installed.

Ap plies to veh icles : w it h gasoline eng ine
Catalyt·c converter
It is very important tha t your emission con trol system
(catalytic c onverte r) is f unctioning properly to ensure
that your vehicle is running in an environmentally sound
manner.
- Always use lead-free gasoline~ page 291, "Gasoline" .
- Never ru n the tan k down a ll the way to empty .
- Nev er put to o mu ch mot or oil in y our engin e~
pag e 306,
"Add ing engin e oil~" -
- Neve r try to push -or tow-start yo ur vehicle .
The catalytic converter is an efficient "clean-up" dev ice built into the
exhaust system of the ve hicle. The catalytic converter burns many of
the pollutants in the exhaust gas before they are released into the
atmosphere. The exclusive
use of unleaded fuel is critically important for the life of
t he c atal ytic converte r and proper f unct ion in g of t he engi ne.
& WARNING
• Do not park or operate the vehicle in areas where the hot
e x haust system may come in contact with dry grass , brush , fuel
s pill or other material whi ch can cau se a fire.
• Do not apply additional undercoating or rustp roofing on or
near the exhau st manifold, exhaust pipe s, catalytic converter or
heat shields. During driving , the substance used for undercoating
c ould overheat and cau se a fire .
0 Note
• Be aware th at just one tank fi lling wit h le aded fu el w ill alre ady
ser iously degrade the performance of the catalytic co nverter.
• Do not excee d the correct engine oil leve l~
page 306.
• Do not drive unti l the f uel tank becomes complete ly empty . The
eng ine could misfire. Unbu rned fuel could also ge t into the exha ust
system and th is could cause the catalytic converter to overheat.
• Do not tu rn off the igni tion whi le the veh icle is moving .
• Do not contin ue to operate your vehicle under these conditions, as
o therwise fuel can reach the cata lytic converter . This could result in
overheating of the converte r, requiring its rep lacement.
• To assu re eff icient operat ion of the Emission Co ntrol System:
- Have yo ur vehicle main taine d pr operly and in a ccordan ce wi th
the service recommendations in your Warranty
& Maintenance
booklet .
- Lack of p roper maintenance as well as improper use of the
veh icle w ill imp air the f unction of the emiss io n con trol syste m and
could lead to damage. ..
