Adaptive Cruise Control
Speed and distance control system
Applies to vehic les : with Adaptive C ruise Cont rol
Description
The Adaptive Cruise Control driver assistance pr ogram is
a combined speed and distance control system .
Fig. 123 Fro nt
bu mper: Pos it io n of
r adar senso r
Adaptive Cruise Control can help make driving more re laxed and
less t iring, particula rly during long trips on interstates or other
highways that are generally straight .
Set ACC to maintain a constant, legal travel speed between 20 and
95 mph (30 -150 km/h) that is appropriate for prevailing traffic
conditions. Select a following distance to the vehicle ahead and ACC
w ill adjust your speed to maintain that distance .
Adaptive Cruise Contro l has technical limitations that you must
know, so please read this section carefully, understand how the
system works and use it proper ly at all times .
How does it work ?
You can operate the Adaptive Cruise Control using the lever on the
steering wheel column=> page 130, "How is the speed stored?" a nd
=> page 133, "How is the distance (time interval) set? ".
Con tro ls and eq uip­
ment
Driver inf ormation
Important information is brought up in the speedometer and in the
instrument cluster display as the ve hicle is being driven
=> page 135, "Driver information" .
What is important for y ou to kn ow
The Adaptive Cruise Control is set with system -specified limits; that
is, as a driver, you will have to adj ust the speed and distance to the
vehic le ahead in some instances=> page 138 , "Driver intervention
prompt" and=> page 140, "System limita tions" .
& WARNING
Improper u se of the Adapti ve Crui se Control can c ause colli sion s,
oth er ac cident s and s eriou s per sonal injur y.
• Alway s reme mber that the Adapt ive Cruise Control ha s limit s -
it will not slow the veh icle do wn or maintain the set dis tance
w hen you drive to w ard s an obst acle or something o n or ne ar the
road th at is not moving, such as vehicle s stopped in a traffi c jam ,
a stalled or disabled vehicle .
• Alwa ys remember th at the Adaptive Cru ise Control can not
dete ct a vehicle th at is driving to ward s you in your tr affi c lane and
th at it can not dete ct n arr ow vehi cles su ch as motorcycl es and
bicycle s.
• Never dr ive at speed s th at ar e too fa st for traff ic, road and
we ather co nd ition s.
• The Adaptive Cru ise Control cannot slow or brake th e vehi cle

Alway s be p rep ared to br ake and take eva sive a ctio n to avoid colli-
s ion s and other a ccident situa tio ns. ._
Vehicle care
I I irechnical data

The direction in which the driver wishes to travel is determined with
t he aid of the steering angle and vehicle speed and is continua lly
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehic le starts hydrop laning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the prob lem.
The vehicle is then stab ilized by the forces acting on the whee l
during braking. If the vehicle is
oversteering (rear tends to skid out
of the turn), the brakes are mainly app lied on the wheel that is on
the outside of the curve. In the case of a vehicle that is
understeering
(tendency to sl ide out of the curve), the brakes are applied at the
rear wheel that is on the inside of the curve . An acoustic signal indi­
cates when ESP brake application cuts in
~ & .
The system operates across the entire speed range in combination
with the ABS system
~ page 266 . If the Anti -Lock Brake System
(ABS) malfunctions, the ESP wi ll be out of action as well.
Ac tivat ing
When you turn on the eng ine, ESP will automatically be activated
and will perform a se lf -test . As soon as the test is comp leted, the
system is in norma l operating mode.
You can activate a deactivated ESP or deactivated ESP/ASR if required by pressing the~
page 262, fig. 232 button . When they are
activated, the message
E S P/AS R on appears briefly in the display.
D eactiv ating
The ESP should normally be activated al l the time . If necessary, you
can deactivate An ti- Slip Regulation (ASR) or the E lectronic Stabiliza ­
tion Program (ESP) by pressing the button~
page 262, fig. 232 .
• Dea ct iv at ing A SR: Tap the button . In certain exceptional situa ­
tions (e.g. driving with t ire chains) , the Anti-Sl ip Regulation (ASR)
can be deactivated ~
page 264. The message ASR off appears in the
display as we ll.
• Dea ctiv at ing E SP/ASR Press the button for more than 3 seconds.
With the ESP/ASR deactivated, the ESP check light comes on, see

& WARNING
The Electroni c Stabili zation Program i s never thele ss subject to the
la ws o f physics . It is p articularl y import ant t o pay a ttent ion t o th is
f a ct on wet and slippery road s. It is ther efore important tha t y ou
a lw ays a dapt your dr iving to the c ondit ion of th e ro ad and t raffi c

Electronic differential tock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
Gener al note s
The electronic differential lock (EDU helps the car to start moving,
accelerate and c limb a gradient on surfaces providing poor or
almost no grip . Without EDL, this would be difficult, if not impos ­
sib le .
How th e sys te m wo rk s
The EDL operates automatical ly . It monitors the rotational speed of
the drive wheels on an axle with the he lp of the ABS sensors
~ page 266 . If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power
to the other drive wheel or whee ls (a ll -whee l drive) . Th is is done up
to a speed of about 60 mph ( 100 km/h). Noises from the brake
system signal that wheel spin is being control led .
Dr iving off
When driving off , always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface

Vehicle care Do-it-yourself service Technical data

This automatic adjustment process will cause a slight vibration of
the brake pedal and some noises to alert you that vehicle speed
must be adapted to existing road and traffic conditions .
& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics .
[ i ] Tips
• If ABS is not functioning properly, a warning light will come on .
See ~
page 21.
• If a fau lt occurs in the ABS, the EDL is also not functioning. This
is indicated by the ABS warning light.
Brake assistant
The brake assistant is designed to achieve the optimum
braking effect.
The brake assistant helps to increase the effective braking power
and thus to achieve a shorter stopping distance . If the driver
presses the brake pedal very quick ly, the brake assistant automati­
cally boosts the braking force to the maximum level, up to the point
where the anti-lock brake function (ABS) intervenes to stop the
wheels from locking . You should then keep the brake pedal pressed
until the vehicle has braked to the required speed. The brake assis­
tant switches itself off as soon as you release the brake pedal.
T he brake assistant wil l not be operative if there is a malfunction in
the ABS .
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
& WARNING
Please remember that the
accident risk always increases if you
drive too fast , especially in corners or on a slippery road, or if you
follow the vehicle ahead of you too closely. Increased risk of an
accident cannot be compensated for even by the brake assistant ,
so always maintain a safe speed. •
Servotronic® -advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort.
The advanced Servotronic ® power steering system senses the road
speed and electronically adjusts power assistance to provide
comfortab le and safe steering response exactly matched to the
vehicle speed.
Power steering will not work if the engine is off. As a result, the
steering wheel will be hard to turn.
The power steering fluid level is checked during the scheduled
maintenance services .
0 Note
If there is an electronic ma lfunction, servotronic wi ll still function
like a conventional power steering system, providing a constant
steering support force that is no longer proportionate to the vehicle
speed . This is most noticeable when turning the steering whee l at
low speeds (for examp le when parking), -more effort will be
required than usual.
• Be aware of the different than usual steering response and
adjust your steering force accordingly.
• Have the problem checked and set right by an Aud i dealer as
soon as possible. ._

[ i] Tips
• When the engine is running, never hold the steering wheel
turned all the way to the right or to the left for longer than
15 seconds . The power steering pump will overheat the hydraulic
fluid if you keep holding th e steering wheel turned all th e way. This
is likely to damage the power steering system.
• If the power steering system should fail entirely, or if the engine
is not running (for example, while being towed), you will still be able
to ste er th e vehicle . However,
considerably mor e effort will be
required to do so.
• If the power steering system should have a leak, or is not func ­
tioning properly, contact your authorized Audi dealer immediately.
• The power steering system requires a specially formulated
hydraulic fluid. The power steering reservoir is the one located most
forward on the left side of the engine compartment=>
page 302. The
correct fluid level in the reservoir is important for proper func­
tioning of the power ste ering. •
Applies to vehicles : wit h A ll Wh eel Drive
Driving with your quattro®
With All Wheel Drive, all four wheels are driven.
General information
With All Wheel Drive, power is distributed to all four wheels. This
happens automatically depending on your driving style and the
road conditions at the time . See also=>
page 263, "Electronic differ­
ential lock (EDU".
Winter tires
When driving in the winter, your vehicle with All Wheel Drive has an
advantage, even with regular tires. In winter road conditions it may be advisable to mount winter tires (or all-season tires) for improved
driveability and braking: these tires must be mounted on
all four
wheels.
See also => page 333, "Winter tires".
Tire chains
Where tire chains are mandatory on certain roads, this normally
also applies to vehicles with All Wheel Drive=>
page 334, "Snow
chains".
Replacing wheels/tires
Vehicles with All Wheel Drive must always have tires of the same
si ze. Also avoid tires with different tread depths. For details see
page =>
page 329, "New tires and replacing tires and wheels".
Off-Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road vehicle. It is therefore best to avoid rough tracks and
uneven terrain as much as possible. Also refer to=>
page 273.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks.
• Although the All Wheel Drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at excessive speeds on icy or slippery
road surfaces.
• On wet road surfaces, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (aqua­ planing}. If this should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive
vehicle. Always drive at speeds which are suited to the road condi­
tions -risk of crash. ,

crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­

& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
