System limitations
General information
App lies to vehicles: with adaptive cruise control
Some driving situations which affect the func­
tion of the radar sensor are described below.
When driving, the adaptive cru ise control is
governed by physical and system-specified
limits. Also, under certain circumstances, the
ACC system may react unexpectedly or late
from the driver's po int of view. Therefore, al­
ways be attentive and intervene, if necessary:
- when driving around curves¢
page 112
-when vehicles in front are not in line with
your vehicle ¢
page 112
-when other vehicles are changing lanes
r:=>page 113
-when other veh icles are difficult to detect
r:=> page 113.
A WARNING
The radar sensor's vision can be reduced by
rain, snow and heavy spray. This can result
in vehicles driving ahead being inade­
quately d etected or, in some c ircumstan­
ces, not detected at a ll.
If ne cess ary, take
a ction yourself!
When driving around curves
Applies to vehicles: with adaptive cruise control

Entering a curve
When enter ing a curve, the adaptive cruise
control may react to a vehicle in the next lane
and apply the brakes in yo ur vehicle
r:=> fig. 122. The braking action can be overrid­
den by depressing the accelera tor pedal.
Leaving a curv e
At the exit from very long curves the pred ic­
t ive lane reading can cause the adaptive cruise
control to react to another vehicle in the next
lane and apply the b rakes in your vehicle
r=>fig . 123. The braking action can be over rid­
den by depressi ng the acce le ra tor pedal.

range of the radar sensor
Vehicles trave ling ahead and to one s ide can ­
not be detected by the adaptive cru ise contro l
unt il they are within the detect ion range of
the sensor.

114 Adaptive cruise control
The Audi braking guard is active from a speed
of approx. 20 mph (30 km/h) and works with­in the system limits¢
page 112 even when
the adaptive cruise contro l is deactivated.
A radar sensor is bui lt into the front of the ve ­
hicle
¢ page 102, fig. 110. The system is in­
tended to measure the distance to reflective
surfaces. If a measurement is not possible,
the system does not respond .
When the measurement has taken p lace, the
system can assess a hazardous situation,
when a vehicle ahead suddenly brakes or when
your own vehicle is driving at high speed to­
wards a much slower vehicle ahead . As soon
as the system assumes that a possible colli­
sion with the vehicle ahead can on ly be avo id­
ed by immediate all-out braking or by an
avoiding maneuver, a warning appears.
The system has a pre-set response time to be
able to warn in good t ime . This system re­
sponse time is automat ically reduced if you
accelerate actively, for example to join a high­
way. Braking, transverse acceleration and the
steering angle can lead to a reduced system
response time . The warning is deactivated if
you begin to overtake with fu ll acce leration.
The system draws your attention to two differ­
ent hazardous situations:
Distance
The distance warn ing is issued in the event of
inadequate distance to the veh icle ahead ape­
riod of more than 5 seconds . If the distance is
l ess than 30 feet (9 meters) at 50 mph
(80 km/h) , for example, an optical display is
faded in on the instrument cluster¢
fig. 129.
If the vehicle ahead brakes sharply, a collision
cannot be avoided , even in the case of an im­
mediate response. In this case, increase the
distance to the vehicle ahead.
Speed
If there is a much slower veh icle ahead in your
la ne, or if the vehicle ahead brakes sharply,
the Audi braking guard ca lculates the point
from which a collision can only be avoided by all-out braking or
by an avoiding maneuver. If
a warning does sound, a possib le collision
with the vehicle in front can be avoided
through an evas ive maneuver or by braking .
T he warning is given in two stages:
-Pre-warning: An optical display appears in
the instrument cluster and a warning tone
so unds.
- Acute warning: If you do not respond to the
pre-warn ing, the second stage , the acute
warning, is issued . A brake jolt reminds you
to concentrate on the road again.
Under heavy brea king, brake assist
¢
page 209 also helps you obtain max imum
braking efficiency.
.&_ WARNING ~
Always pay attention to traffic, even when
the Audi braking guard is switched on. You
are a lways responsible for your speed and
the distance between your vehicle and oth·
er vehicles.
-Always keep the lega lly stipulated safety
d istance between your vehicle and the
veh icle ahead • danger of accident!
- The Audi braking guard does not respond
outside the system limits, for example if
you approach a stationary obstacle (end
of a traff ic jam or breakdown vehicle).
- Please observe that the Audi braking
guard is subject to restrictions in narrow
bends due to the field of vision of the ra­
dar senso r. T his may possibly lead to ob­
stacles not being detected.
- The radar sensor's
vision can be reduced
by rain, snow and heavy spray. This can
resu lt in vehicles driving ahead being in­
adequately detected or, in some circum­
stances, not detected at all. Always
watch where yo u are driving .
- Reflecting objects such as e.g . crash bar ­
riers or the entrance to a tunne l may im­
pair the function of the radar sensor .

vertical axis, vehicle acceleration in the fore ­
and-aft and lateral directions , the brake pres­
sure, and the steering ang le are all measured .
The direction in which the d river wishes to
travel is determined with the aid of the steer­
ing angle and vehicle speed and is continually
compared with the actual behavior of the ve­
h icle. If the two do not match, for examp le,
when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appro­
priate wheel to correct the problem.
The vehicle is then stabili zed by the forces act ­
ing on the wheel dur ing braking. If the vehicle
is
oversteering (the veh icle turns too sharply
and the rear wheels sl ide toward the outs ide
of a curve), the brakes are main ly applied on
the wheel that is on the outside of the curve.
I n the case of a ve hicle that is
understeering
(the vehicle does not turn sha rply enough and
pushes out of a curve) , the brakes are applied
as needed on the whee l that is on the inside of
the curve o r additiona lly on the other wheels.
An acoust ic signal indicates when ESP brake
application cuts in
q .& .
The system operates across the entire speed
range in combination with the ABS system
q page 208. If the Anti-Lock Brake System
(ABS) malfunctions, the ESP will be out of ac­
tion as well.
Acti vating
When you turn on the engine, ESP wi ll auto­
matica lly be activated and will perfo rm a se lf­
test. As soon as the test is completed, the sys­
tem is in normal operating mode .
You can activate a deactivated ESP or deacti ­
vated ESP/ASR if required by pressing the
qfig. 196 q fig . 195 button. When they are
activated, the message

appears briefly in the d isplay.
D eacti vating
The ESP sho uld normally be activated all the

.8, WARNING -
The Electronic Stabi liz a tion Program is
neverthe less subjec t to the laws o f phys­
ics. It is part icu la rly important to pay a t­
tention to this fact on wet and slippery roads. It is therefo re important that you
a lways adapt your driving to the condit ion
of the road and traff ic conditions. Do not
allow the increased safety provided by the Elect ronic Stabilization Program system to
lull you into accepting addit iona l safety
r isks.
Electronic differential lock (EDL)
The electronic differential lock monitors the
rotational speed of the drive wheels .
General not es
The electronic d ifferential lock ( E0L) he lps the
car to star t moving, acce lerate and climb a
gradient on surfaces providing poor or almos t
no grip . Without EDL, this would be d iff icult,
if not impossible .
How the sy stem works
The EDL operates automatically. It mon itors
the rotational speed of wheels with the he lp
of the ABS sensors
q page 208 . If a noticea­
ble
slip is detected at the wheels (e .g . on s lip ­
pery ground
on one side), the sp inning wheels
are braked and power is t ransferred to the
othe r whee ls. Thi s is done up to a speed of
abo ut 60 mph (100 km/h) . Noises from the
brake system signa l that wheel spin is be ing
controlled .

206 Intelligent technology
Driving off
When driving off, a lways be sure to keep road
conditions in mind as you accelerate. If one
drive wheel spins because it is on a surface
with less grip, apply
plenty of throttle until
the car starts to
move .
Overheating of brakes
To prevent the disc b rake o f the bra ked wheel
from overheating if subjected to excessive l oads on this whee l, the EDL cuts out tempo­
rarily. The vehicle remains operational and be­
haves in the same way as a vehicle without
EDL.
As soon as the brake has coo led down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be careful
when depressing the accelerator pedal. Even with the EDL working, the drive
wheels can spin and reduce your ability
to control your car. Risk of crash!
- The increased safety afforded by EDL
does not mean that you can take safety
risks. Always adapt your dr iving style to
the road conditions and traffic situation.
0) Tips
If a fault occurs in the ABS, the EDL is also
not funct ion ing. Thi s is indicated by the
ABS war ning light ¢
page 16.
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the
driven wheels from spinning when the car is
accelerating.
General notes
The Anti -Slip Regulation System (ASR) is inte­
grated in the electronic stabilization program
( E SP). When the vehicle starts up and acceler­
ates, the wheels are p revented from spinning
by adjusting the engine power to match the amount of grip available
from the road sur­
face.
How the system works
ASR performs automat ically, i .e. w ithout the
driver's intervention. With the aid of the ABS
sensors ¢
page 208, ASR monitors the speed
of the driven whee ls. If the whee ls start to
spin, engine torque is reduced automatica lly
until the tires find enough grip to lock onto
the road surface. The system is active across
the entire speed range.
The ASR works in conjunction with the ABS . If
a malfunction should occur in the ABS, the
ASR will also be out of act ion.
Activating
T he ESP is automatica lly activated when the
engine is started and it performs a se lf-test .
You can activate a deactivated ASR if required by pressing the
¢ page 204, fig. 196 button.
When it is act ivated, the message
ESP/ASR
on
appears briefly in the display .
Deactivating
You can deactivate the ASR if required by
pressing the button (for less than 3 seconds)
¢
page 204, fig . 196. With the ASR deactivat­
ed, the ESP check light comes on, see
¢
page 15 . The message ASR off appears in
the d isplay as well. The ASR can be deact ivat­
ed at any speed.
The ASR s hould normally be activated all the
time . Only in certain exceptional situations
when some slip is desirable does it make
sense to deact ivate the ASR . Examples :
- when driving with tire cha ins
- when driving in deep snow or on loose
ground and
- when rocking the vehicle loose after it has
become stuck.
When the abnormal situation is
over, you
shou ld activate the ASR again .

A WARNING ,~
The increased safety afforded by ASR does
not mean that you can take safety r isks .
Always adapt your driv ing style to the road
conditions and traffic situation .
@ Tips
To ensure that the ASR works properly, all
four wheels must be fitted with identical
tires. Any differences in rolling radius of
the t ires can cause the system to reduce
engine power when this is no t des ired. See
also ¢
page 263, 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, depend ing largely on operat ­
ing conditions and dr iving habits ~.&. . On ve­
h icles that are either driven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your a uthor­
ized Audi dealer more often than specified i n
the
Warranty & Maintenan ce booklet . Failure
to have your brake pads inspected can result
in red uced brake performance.
On steep slopes, you should use the brak ing
effect of the eng ine . This way, you p revent un­
n ecessary wea r on the brake system . If you
must use you r brakes, do not ho ld the bra kes
down continuously . Pu mp the b rakes at in ter ­
va ls.
Noises may occur when braking depending on
the speed, bra king for ce and outside condi­
tions s uch as temperatu re a nd humidity .
Moisture or road salt
If you are driving faster than 31 mph (SO km/
h) and the windsh ie ld w ipers are on, the brake
pads will briefly touch the b rake d iscs in regu­
l ar i nte rva ls so as to imp rove reaction t ime
Int ellig ent technolog y 207
when b rak ing on wet surfaces . You, the driver,
will not notice anything.
U nder certa in cond itions , fo r example, when
d riv ing th rough wa ter or very heavy ra in , or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads. A
few carefu l brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the brakes can be red uced
when the vehicle is driven on a salt-covered
road and the brakes are not used. Here too,
you should clean off accumulated salt coating
from brake discs and pads w ith a few careful
applications of the brake¢,&. .
Corrosi on
There may be a tendency for dirt to b uild up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regularly or
o nly for short trips w ith litt le use of the
brakes .
If the brakes are no t used frequently, or if cor­
ros ion has formed on the discs, i t is adv isable
to clean off the pads and d iscs by braking
firmly a few times from a moderately high speed ¢,& .
Fault s in the brake s ystem
If you should notice a sudden increase in
brake pedal trave l, then one of the two brake
c ircuits may have failed ¢,&. .
Lo w br ake fluid le vel
Malfunctions can occ ur in the brake system if
the brake fluid level is too low. The brake flu id
level is monitored electronically.
Brake lining wea r status
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 for th is in­
spection ¢

,8. WARNING
- You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road condit ions permit .
Other road users must not be put at r isk -
you may cause an acc iden t!
- 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 cou ld 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
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 can
accumula te 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 fo r an extended period of time on
salt -covered roads w ithout using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads w ith a few careful
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 ent ire brake system.
- Failure of one brake c ircuit 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 authorized 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
runn ing
c> .&. .
,8. WARNING
-Never let the vehicle 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 bra ke pedal mus t 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 .
-
The ABS contributes effect ively to vehicle con­
trol since it prevents the whee ls from
locking
when the brakes are applied. This means that
the ve hicle remains steerable and is less likely
to skid .
With AB S you do n ot need to pump the
brake . Ju st hold th e bra ke p edal down.
However, do not expect the ABS to s horten
braking distance under
all c ircumstances.
When driving on gravel or on new ly fallen
snow on top of icy surfaces, 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 syst em work s
An automat ic check is made when a speed o f
about 12 mph (20 km/h) is reached. When
this happens, a pumping noise can be heard.
If an ind iv idual whee l begi ns to rota te too
s lowly in re lation to vehicle speed and tends
to lock, the ABS automatically reduces brake pressure to prevent that whee l from locking . .,..

Driving and
environment
The first 1
1000
miles
(11500 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 mile s (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 .
From 600 to 1,000 miles (1 ,000 to
1,500 kilometers ):
.. Speeds ca n gradually be increased to the
maximum perm iss ible road or eng ine speed .
During and after br eak-in period
.. Do not rev the eng ine up to h igh speeds
when it is cold. Th is applies whether the
transmission is in N (Neutral) or in gear.
After the break- in peri od
.. Do not exceed maximum 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
c.> page 10.
During the first few hours of driving, the en­
g ine's internal friction is higher than later
when all the moving parts have been broken
in . How well this break -in process is done de ­
pends to a considerable extent on the way the
vehicle is driven du ring the first 1,000 miles
(1,500 kilome ters).
(D Note
Extremely h igh engine speeds are auto­
mat ica lly reduc ed. However, t hese rpm
lim its are programmed for a n engine well
r u n- in, not a new engine.
Driving and environment 213
@) For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds -upshifting ear ly saves f uel,
reduces noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
very carefully for the first 350 miles (500 ki lo­
meters) after fitting.
.&, WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be sure to remember
this dur ing the f irst 350 m iles (500 kilo­
meters) . Brake gently . Avoid fo llowing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
New brake pads
Remember that new brake pads do not have a
full brak ing effect dur ing the first 250 m iles
(400 ki lomete rs) afte r they are installed.
New brake pads have to be "burnished in" be­
fore they have optima l grab
c.> .&. .
During the brea k-in period, yo u should avo id
putting severe loads on the brakes. Severe
l oads include , for example, sudden hard brak­
i ng, in particular at very h igh speeds or, for
example, on mountain passes .
.&, WARNING
New b rake pads don 't have the best stop­
p ing power and must be "broken-i n" dur­
ing the initi al 100 to 150 miles (150 to
200 kilometers) o f no rma l ci ty driving . You
can compensate for this by pressing the b rake peda l more firm ly . This also applies
later when new pads are installed.

214 Driving and en vironm ent
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.
This 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 higher tha n the
bottom o f the vehicle body.
- Do not d rive faster than wa lking speed.
_& WARNING
After d riving through water, m ud, slush,
et c., the brakes may be slow to take effect
because o f wet brake ro tors and pads . Dry
the brakes fi rst by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not stop the veh icle, dr ive in reverse
or switch 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 salt water because
it can ca use corrosion.
-
Catalytic converter
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¢ page 232,
Fuel supply .
.,. Never run the tank down all the way to
empty .
.,. Never put too much motor o il in your en-
gine ¢
page 242, ~ Adding engine oil .
.,. Never try to push- or tow-sta rt you r vehicle.
The catalytic converter is an efficient "clean­
u p" dev ice built into the exhaust system of
the vehi cle. The cata lytic conve rter bu rns
many of the pollu tan ts in the exha ust gas be­
f o re they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
important for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engine.
A WARNING
- Do not park or operate the vehicle in
areas where the hot ex haust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
r u stproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converte r.
- Do not exceed the correct engine oil level
¢page 242.
-Do not drive until the fuel tank becomes
completely empty . The engine co uld mis-
fire. Unburned fuel could also get into ..,.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not continue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter. This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your personal driving style
- operating conditions
- technical lim itations
I f you anticipate what you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 215
fuel consumption by 10 -15 percent. Th is sec ­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as published
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.. Avo id unnecessary accelerating and brak ing .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you ant icipate what is going to
happe n next, you will need to brake less and,
t hu s, accele rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well below your car's maxi -
mum speed .
Accelerat ing gently reduces fuel consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.
