Audi adaptive cruise
control
Description
A pp lies to: ve hicles w ith Audi adaptive cruise co ntro l
F ig. 88 Detection range
The adaptive cruise control system is a combina­
tion of speed and distance regulation.
It assists
the dr iver by bot h regula ting the speed and
maintaining a distance to the vehicle driving
ahead, within the limits of the system .
If the sys­
tem detects and object ahead, adaptive cruise
control can brake and accelerate your vehicle.
This makes driving more comfortable both on
long stretches of hig hway and in stop-and-go
traffic .
What c an adapti ve crui se control do ?
The adaptive cruise contro l system uses video, ra­
dar and ultrasound. Objects driving ahead can be
recognized up to 650 feet (200 m) away.
On open roads with no traffic, it functions like a
cruise control system . The stored speed is main­
tained. When approaching an object ahead, the
adaptive cruise control system automatically brakes to match that object's speed and then
maintains t he stored d istance . As soon as the
system does not detect an object ahead, adaptive
cru ise control acce lerates up to the stored speed .
In stop-and-go traffic, adaptive cru ise control can
brake unt il the vehicle is stat ionary and then be­
g in driving aga in under certain conditions

Fig. 89 Fro nt of th e vehicle: senso rs a nd video camera
The areas that contain the rada r and ultrasonic
senso rs and the video camera
c::> fig . 89 must not
be covered by stickers, deposits or o ther objects
because this can interfere with the function of
the adapt ive cruise control system and braking
guard . For info rmation on clea ning, see
¢ page 221. The same applies for any modif ica­
tions made in the front area.
The function of the adaptive cru ise control sys­
tem and braking guard is limited under some
cond itions.
- Objects can only be detected when they are
w ith in the sensor range
<=:>page 86, fig. 88.
- The system has a l imi ted abili ty to detect ob­
jec ts that are a sho rt d istance ahead, off to the
side of your vehicle or moving into your lane.
- Obje cts that are d ifficult to detect such as mo­
torcycles, veh icles with high ground clea rance
or an overhanging load are detected late or not
detected at all.

Assistance systems
In curves
Applies to: vehicles with Audi adaptive cruise contro l
Fig. 90 Example: dr ivi ng into a curve
When driving into a curve ¢ fig. 90 and out of a
curve, the adaptive cruise control may react to an
object in the ne ighbor ing la ne and apply the
brakes. You can p revent that by pressing the ac­
celerator pedal b riefly.
Stationary objects
Applies to: vehicles with Audi adaptive cruise control
F ig . 91 Example: object changi ng lanes and stationa ry o b·
j e ct
The adaptive cruise contro l system only reacts to
objects that are moving or that the system has
already detected as moving. For examp le, it can
react when a vehicle that has already been de­
tected @turns or changes lanes, but adaptive
cru ise control does not react to a stat ionary vehi­
cle @.

Ass is tanc e system s
What can the braking guard do?
When detected in t ime, the system can assess
dangerous situations where an object ahead
brakes suddenly or if your own vehicle is traveling
at a high speed and approaching an object that is moving more slowly. The braking guard does not
react if it cannot detect the s ituation.
The system advises you of various dangerous sit­ uations :
- T he
dista nce warning occurs if you d rive too
closely to the object ahead for a long period of
time. If the object ahead brakes strongly, you
would not be able to avoid a collision .
The.
indicator light appears as an indication for this.
- The
app ro ach warning occurs when an object
ahead is traveling more slow ly or brakes
strongly. When th is warning occurs, it may only
be possible to avoid a co llision by swerv ing or
braking strongly . The danger is indicated by the
• ind icator light ¢ fig . 98 . An aud io signal w ill
also sound .
If you do not react early enough or at all to a dan­
ge rous situation, the braking guard suppo rts you
with a brak ing intervention .
- If a collision is imminent, the system will f irst
provide an
a cut e warn ing by braking sharply.
- If you do not react to the acute warning, the braking guard can increase the braking force
within the limits of the system
ll . Th is reduces
the vehicle speed in the event of a collision .
- The system can init iate comp lete deceleration
shortly before a collision
ll _ Full deceleration at
high speeds occurs only in vehicles with adap­
tive cru ise control and s ide ass ist (pre sense
pl us).
- If the braking gua rd determines that you are
not brak ing strongly enough whe n there is an
im pending co llision, it can increase the bra king
force .
- T he pre sense functions also engage whe n
t h ere is an impend ing collision ¢

Which fun ction s can be controlled?
Yo u can swi tch the braking guard and the d is­
tance/approach warning on or
off in the Infotain ­
ment system ¢
page 93, Settings in the Info ­
tainment system .
A WARNING
Lack of attention can cause collisions, other
accidents and ser ious personal injuries . The
braking guard is an assist system and cannot
prevent a collis ion by itself . The dr iver must
a lways intervene. The d river is always respon­
sib le for braking at the co rrect t ime.
- Always pay close attention to traffic, even
when the b raking guard is sw itched on. Be
ready to intervene and be ready to take
co mplete co ntro l whenever necessa ry . Al ­
ways keep the sa fe and legal distance be ­
tween your vehicle and ve hicles up ahead .
- Br aki ng g uard wo rks w ithin limits and w ill
no t respond outside the system limits, for
examp le when approaching a stopped vehi ­
cle or stationary obstacle (end of a traffic
jam or ve hicle that has broken down in traf ­
fic).
- Always remember that the radar sensor for
the brak ing guard works only within defined
detection and range limits that may prevent
the proper detection of other vehicles .
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Mov ing veh icles up ahead may not be
promptly detected or may not be detected
at al l.
- Reflective surfaces including crash ba rr iers
or tunne l entra nces may impair the function
of the rada r senso r.
(D Tips
- You can cancel the braking with increas ing
force that is initiated by the system by brak­ ing yourse lf, by acce le rating not iceably or
by swerv ing.

" N .... 0 0 \,;J ' Intelligent Technology Electronic stabilization
control (ESC)
Description
Electronic stabilization control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critica l sit­
uations such as the vehicle oversteering and un­
dersteering or the wheels are spinning. The vehi­
cle is stabilized by applying the brakes or reduc­ ing engine torque. As soon as the ESC is actively
regulating, the
If] indicator light b links in the in­
strument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is act ing to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situat ion is over . In veh icles
with adaptive cruise contro l*, the brake assist
system is more sensitive if the distance detected
to the vehicle dr iv ing ahead is too small. On
vehicles with activated and functioning night vi­
sion assist*, the brake assist system can respond more sensitively if there is a warning .
Anti-Slip Regulation (ASR)
ASR reduces eng ine power when the drive wheels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL applies the brakes to a whee l that starts
spinning and transfers the drive power to the
other driving wheel or wheels (if the vehicle is
Intelligent Technology
equipped with a ll wheel drive*). This function is
not avai lab le at higher speeds.
In extreme cases , EDL automatically switches off
to keep t he brake on the braked whee l from over ­
heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi­
tions have returned to normal.
Power steering
The ESC can also support veh icle stability
through steering .
Selective wheel torque control
Selective wheel torque control is used when driv­
i ng on curves. The front whee l on the ins ide of
the curve or both wheels on the ins ide of the
curve are braked selectively as needed. This al­
lows more precise driving in curves.
Automatic post-collision braking system
The "automat ic post-collis ion braking system"
can help to reduce the risk of sliding and of addi­
tional collisions after an accident. If the airbag
contro l module
detects a co llision above a certa in
vehicle speed, the vehicle is braked by the ESC.
T he vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri­
cal system are not functioning.
A WARNING
-
- The ESC and its integrated systems cannot
overcome the lim its imposed by natura l
p hys ica l laws. This is especially impo rtant
on slippery or wet roads. If the systems be­
g in acting to stabilize yo ur vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the increased safety provided tempt
you into taking risks. This could increase
your r isk of a coll is ion.
- Please note the risk of a coll ision increases
when dr iv ing fast, especially through curves
and on slippery or wet roads, and when

driving too close to objects ahead . The ESC
and its integrated systems cannot always prevent coll isions

cidents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such as ice and snow . The drive wheels can spin

led and this can affect driving stability and
increase the risk of a collision.
(D Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine .

Brakes
New brake pads
New brake pads do not achieve their full braki ng
effec t during the first 2SO mi (400 km). They
must be "broken in" first.

a co .... N
" N .... 0 0 \,;J ' Wear Brake pad
wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently
in the city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy ra in, after overnight con­
densat ion or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
"dried" first with a few careful brake applica ­
tions.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time. This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather .
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
f ir st when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avo iding heavy brak ing
can contribute to corrosion on the brake rotors
and to d irty brake pads .
If you usually avoid heavy braking or if there is
corros ion present, occasional heavy braking at
high speeds is recommended to clean the brake
rotors and
pads¢ &..
Brake system malfunction
If you notice that the brake pedal travel has sud­
denly
increased, then a brake circuit in the dual­
circu it brake system may have malfunct ioned.
Drive to an authorized Aud i dealer or authorized
Intelligent Technology
Audi Service Facility immediately to have the
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake peda l harder.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur . The brake fluid level
is e lectronically monitored.
Brake booster
T he brake booster amplifies the press ure you ap­
ply to the brake pedal. It on ly works w hen the en­
gine is running.
A WARNING
-
-Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic cond itions permit. You must not en­
danger other road users. This increases the
risk of an accident .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident .
- New brake pads do not ach ieve the ir full
braking effect dur ing the first 250 m i
(400 km). They must be "broken in" first .
However, you can compensate fo r the
slightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy b rak­
ing during the break -in period.
- Ce rtain weather and operating conditions
such as driving through water, dr iv ing in
heavy rain or driving after washing your ve ­
hicle can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these components by braking carefully. Ap­
plying the brakes carefully several times
dries the brakes and removes ice build-up .
- The efficiency of the brakes can also be im­
pa ired by dr iv ing for long stretches on roads
covered with salt without using the brakes.
You can remove salt deposits from the
brake rotors and pads by carefully applying
the brakes several times.
121

Intellig ent T echn olo gy
- If the front spoiler is damaged or you insta ll
another spoiler, make sure the front wheel
brakes are venti lated properly. Otherwise,
the brake system could overheat, wh ich re­
duces the ir effectiveness .
- Failure of a brake circuit impairs braking
performance, which increases brak ing dis­
tance. Avoid driving the vehicle and have it
towed it to the nearest author ized Audi
dealer or author ized A udi Se rvice Fac il ity.
- If the brake booster is not working, you will
have to press muc h ha rde r on the bra ke
peda l to compe nsate for the lack of the
booste r.
0 Note
- Neve r let the brakes "rub" by press ing the
pedal light ly when bra kin g is not actually
ne cessa ry. Th is ca u ses the brakes to over ­
hea t an d increases bra king d istance and
causes wear.
- B efo re dr iv ing downh ill a long distance on a
steep hi ll, de crease your speed and se lec t a
l ower gear . This makes use of the engine
braking effect and relieves the brakes . If
you need to brake additionally, brake in in­
tervals and not continuously.
(D Tips
- If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit your vehicle with a front spoil ­
er, whee l covers or s imilar items, make sure
that the a ir flow to the front whee ls is not
i nterrupted. Otherw ise the brake system
can become too hot .
