possible.
A WARNING
- If the E (USA models) ,11J (Canada
models) warning light does not go out,
or if it comes on while driving, the ABS
system is not working properly. The vehi­
cle can then be stopped only with the
standard brakes (without ABS). You will
not have the protection ABS provides.
Contact your authorized Aud i dea le r as
soon as possible .
-USA models: If the 1111 warn ing light
and the
E warn ing light come on to­
ge ther, 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
immediately by your authorized Audi
dealer or a qualified workshop. Dr ive
slowly and avoid sudden, hard brake ap­
plicat ions .
-Canada models: If the brake warn ing
light . and the ABS warning light

that must have a certain size. The system re­
sponds only after the distance measurement has been made. If a measurement is not pos­
sible, the system cannot respond and w ill not
react to a vehicle or someth ing else up ahead.
Open road
When the road is clear, the adaptive cruise
contro l works like cr uise control. It maintains
a constant target speed specified by the driv­
er.
Driving in traff ic
If a slowe r vehicle driving ahead is detec ted,
the adaptive cruise contro l decelerates (within
the limits of the system)

to its speed and after adjust ing,
tr ies to maintain the set distance from the ve­
h icle ahead. The vehicle may temporarily drive
slower than the set speed while adjust ing
¢ & in Description on page 113 .
If the vehicle in front accelerates, adaptive
cruise control also accelerates up to the speed
that you have set.
If the vehicle ahead slows to a stop, ACC will
slow your vehicle down and to a complete
stop if this is possible w ith in the system's lim ­
its and capabilities . ACC will not make an
emergency stop. The text message
ACC off :
manual c ontrol!
appears in the instr ument
cluster display . Once the veh icle stops, you
must depress the brake pedal to prevent the
vehicle from moving forward or "creeping". Depressing the brake pedal turns
off ACC.
When the veh icle ahead accelerates you can
reactivate ACC
¢ page 118, as soon as your
ve hicle has reached a speed of 1 mph (2 km/
h) .
Situ ation s re quiring dri ver int ervention
In some s ituations you w ill have to use the
footbrake to s low the vehicle down in order to
keep a safe distance from vehicle in front of
you or to avo id a rear-end coll is ion. In this sit­
uation, a symbol appears and a warning tone
sounds

Passing another vehicle
If you move in to the passing lane and no ve hi­
cle is detected ahead, the adaptive cr uise con­
trol acce le rates to the speed you have set and
maintains it.
Overr iding ACC
You can in cr ease yo ur speed at a ny time by
stepping on the accelera tor ped al. A fter you
release the accelerator peda l, the system ad­
justs back down to the speed you prev ious ly
set .
Reducing stopp ing distance
If the radar sensor detects that the d istance
to the vehicle a head is less than de fined m ini­
mum distance, the brakes are automatically
prepared fo r emergency braking by the driver .
The brake pads are moved very close to the brake d iscs without actually braking the vehi­
cle. This brake assistant feature reacts more
quick ly to the dr ive r's brak ing, and also works
when adapt ive cruise control is off . The stop­
ping distance is reduced as a result of th is ad­
vance brake p reparation . Th is fun ction does
not perform any emergency b rak ing mane u­
vers by itse lf; the dr iver mus t always apply the
brakes.
A WARNING
If ACC initiates a braking maneuver, the brake pedal w ill be retracted. Inter ference
with the brake peda l can prevent ACC from
slowing the veh icle down and cause a
crash and serious personal injury.
- Never put anything in the driver's foot­
well or let anyth ing fall into it. An object
in the driver's footwe ll can interfe re with
the peda ls and prevent the acce le rator
from being used to override ACC or pre­
vent ACC from being switched off when
the brake pedal is depressed and also
prevent the vehicle from being slowed
down or stopped .
- On ly use floor mats that keep the area
around the peda ls free and that can be
securely fastened to the footwell .

228 Intelligent technology
To ensure that the ASR works properly, all
four wheels must be fitted with identical
tires. Any differences in rolling rad ius of
the t ires can cause the system to reduce
engine power when this is not desired. See
also¢
page 291, New tires and replacing
tires and wheels.
Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automob iles are st ill
subject to wea r, depending la rgely on operat­
ing cond itions and dr iv ing habits
Q ,& . 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
ized Audi dealer more often than specified in
the
Warranty & Maintenance booklet . Failure
to have your brake pads inspected can result
in reduced brake performance .
On steep slopes, you shou ld use the braking
effect of the engine. This way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down continuously . Pump the brakes at inter­
va ls.
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Moisture or road salt
Under certain conditions, for examp le, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the brake pads. A
few careful brake applications should dry off
the brake pads o r remove any ice coatings.
When you are driving at higher speeds with
the w indshield wipers on, the brake pads will
brief ly touch the brake discs in regular inter- vals so as
to improve reaction time when brak ­
ing on wet surfaces . You, the driver, will not
notice anything.
T he effect iveness of the brakes can be reduced
when the vehicle is driven on a sa lt-covered
road and the brakes are not used . Here too,
you should clean off accumulated sa lt coating
from brake discs and pads w ith a few careful
applications of the brake¢,&.
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regu larly or
only for short trips with litt le use of the
brakes.
If the brakes are not used frequently, or if cor­
rosion 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
c> ,& .
Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ir cuits may have fa iled
c> ,& .
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
l evel is monitored electronically .
Brake lining wear status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
through the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spect ion
c> page 304, Changing a wheel.
A WARNING
-- You shou ld perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Othe r road users must not be put at risk -
you may cause an accident!

-Before descending a steep grade, reduce
speed and shift transmiss ion 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
brakes to get hot and dimin ish braking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when you do not intend
to brake. Th is may cause the brakes to
overheat, prema ture wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced . In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful brake applications.
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake 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
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­
est author ized Audi dealer or qualified
workshop .
Brake booster
The brake booster adds extra braking power.
The brake booster works with vacuum pres­
sure which is created only when the engine is
running¢ &,.
Int ellig ent technolog y 229
A WARNING
-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
pressed considerably harder to make up
for the lack of booster assistance .
Functioning of Anti-Lock Brake System
(ABS)
ABS prevents the wheels from locking up un­
der braking.
T he ABS contributes effect ively to vehicle con­
trol s ince it preve nts the whee ls from
locking
when the brakes are applied. This means that
the vehicle remains steerable and is less likely
to skid .
With ABS y ou do not n eed to pump the
bra ke. Just h old t he br ake ped al d own .
However, do not expect the ABS to shorten
braking distance under
all circumstances.
When dr iving on g ravel or on new ly fallen
snow o n top of icy s urfaces, braking dis tance
may be even longer, therefore, under these
circumstances, it is especia lly important that
you drive s low ly and with great care.
How the ABS s ystem works
An a utomat ic check is made when a speed of
about 12 mph (20 km/h) is reached . When
th is happens, a pumping noise can be heard.
If an ind iv idual whee l begi ns to rotate too
s low ly in relation to vehicle speed and tends
to lock, the ABS automatically reduces brake
pressure to prevent that whee l from locking .
T his automatic adjustment p rocess will cause
a
sli ght vibrati on of the brake pedal and some
noises to a le rt you that ve hicle speed m ust be
adapted to existing road and traffic condi ­
tions. •

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 drive at engine speeds that are more
than 2/3 of the max imum permitted RPM.
From 600 to 1,000 miles (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 per iod
... Do not rev the eng ine up to h igh speeds
when it is cold. Th is app lies whether the
transmission is in N (Neutral) or in gear.
After the brea k-in period
... Do not exceed max imum eng ine speed un­
der any circumstances.
... Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ometer scale¢
page 10.
During the first few hours of driving, the en­
g ine's inter na l friction is higher tha n later
when alt the moving parts have been broken
i n. How welt this break- in process is done de­
pends to a conside rable extent on the way the
ve hicl e is driven du ring the first 1,000 miles
(1, 500 kilome ters).
(D Note
E xtremely high engi ne speeds are auto­
mat ica lly re duced. However, these rpm
lim its are programmed for a n engine welt
r u n- in, not a new eng ine.
{® 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 "broken -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¢
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 mus t be "broke n-in " dur­
i ng the in iti al 1 00 to 150 mi les (150 to
20 0 kilometers) of no rma l city driving . You
can compensate for this by pressing the
br ake peda l mo re f irm ly . This also applies
l ater when new pads are installed.

240 Driving off road
If the vehicle threatens to tip over when
driving across a slope , you must immediate­
ly steer downhill in the di rection of the
slope.
D o not par k your veh icle on steep slopes or
g rades .
T o reduce t he risk of tippi ng over, dr ive o n
slopes in the d irection o f the downwa rd slope
(fa ll line) -
not cros swise .
A WARNING
After drivin g through wate r, m ud, slush ,
etc ., the brakes may be slow to take effect
because of wet b rake roto rs and pads. Dry
the brakes f irst by braking carefully to re­
store the full braking effect.
-
(D Note
Vehicle components s uch as the engine,
transmiss io n, suspension or elect rical sys ­
tem can be severely damaged by drivi ng
through wat er.
(1) Tips
- Check the depth of the wate r before dr iv­
i ng th rough it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off whe n driving
t hr ough water .
- Keep in mind that oncoming vehicles may create waves that raise t he water
l eve l and make it t oo deep fo r yo ur vehi­
cle to dr ive th rough safely.
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
