Audi active lane assist
Description
Applies to: veh icles with Audi active lane assist
Active lane assist detects lane marker lines with ­
in the limits of the system using a camera in the
windshield. If you are approaching a detected lane marker line and it appears likely that you
will leave the lane, the system will warn you with
corrective steering . You can override this steering
at any time . If you pass over a line, the steer ing
wheel will v ibrate lightly. In order for this warn­
ing vibration to occur, it must first be sw itched
on in the Infotainment system. Active lane assist
is ready for operation when the lane marker line
is detected on at least one side of the vehicle.
The system is designed for driving on express­
ways and highways and therefore only activates
at speeds above approximately 40 mph (65 km/
h).
Applies to: vehicles with s ide assist
If you activate a turn signal when active lane as­
sist is ready and it classifies a lane change as crit­
ical because of vehicles traveling alongside you or
approaching you, there will be noticeable correc-
Assistance systems
tive steering shortly before you leave the lane.
This will attempt to keep your vehicle in the lane.
Applies to: vehicles w it h out side ass ist
The system will not warn you before crossing a
lane marker line if you have activated the turn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
Applies to: veh icles w it h adaptive cruise contro l
The corrective steering is targeted based on the
driving situation. In addition to the lane marker
lines , the system can also take into account other
objects such as guard rails . If they are detected in
close proximity to the vehicle, active lane assist
helps prevent the vehicle from driving too close
to them. There is also passing ass istance. The
system does not provide any corrective steering if
it detects that you are passing another vehicle.
A WARNING ~ -
-The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al­
ways keep your hands on the steering
wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking.
- There may be cases where the camera does
not recognize all lane marker lines. Correc­
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected.
- Other road structures or objects could possi­
b ly be identified unintentionally as lane
marker lines. As a result, corrective steering
may be unexpected or may not occur.
- The camera view can be restricted, for ex­
ample by vehicles driving ahead or by ra in,
snow, heavy spray or light shining into the
camera. This can result in active lane assist
not detecting the lane marker lines or de­
tecting them incorrectly .

Audi drive select (drive
settings)
Introduction
Drive select makes it possible to experience dif­
ferent types of vehicle settings in one vehicle .
The driver can se lect
Comfort , Auto and Dynamic
modes in the Inf ota inme nt system to switch be­
tween, for example, a sporty and a comfo rtable
driving mode .
I n the
Individual mode, the sett ings can be ad­
justed to your perso nal preferences. This makes
it poss ible to comb ine settings such as a spo rty
engine setting with light steering.
Description
The following systems, among other things, are
influenced by drive select:
Engine and automatic transmission
Depending on the mode , the engine and a uto­
mat ic tran smission respond more quickly or in a
mo re balanced manner to accelerator peda l
104 movements
. In the sporty dynamic mode, the
transmission shifts at higher speed ranges.
Adaptive air suspension*
The adaptive a ir suspens ion* is an electron ically­
controlled air suspension and damping system.
The adjustment depends on the driving mode se­
l ected, steering movements, the driver's braking
and acce leration, and as the road surface, vehicle
speed and load.
The vehicle ground clearance depends on the
mode selected and the speed . When you are in
the
auto mode, the highway setting is activated
when you drive above 75 mph (120 km/h) for
more than 30 seconds. The ground clearance is
i ncreased automatically if the speed drops below
44 mph (70 km/h) for more than 120 seconds .
Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is especia lly
su ited to long drives on a highway. The dynamic
mode provides sporty, direct steering.
App lies to: vehicles wit h dynamic steer ing
The steering ratio changes based on vehicle
speed in order to maintain optimum steering ef ­
fort for the driver at all times. Th is sets the steer­
i ng to be less sensitive at h igher speeds in order
to provide improved veh icle control. At reduced
speeds, steering is more direct in o rder to keep
t h e steer ing effort as minimal as possible whe n
the driver is maneuvering the vehicle. At low and
average speeds, dynamic steering* additionally
provides more responsive steering performance.
Sport differential*
As a component of the all whee l dr ive system
(quattro)
~ page 123, the sport differe ntial dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies from ba lanced (comfort) to sporty
(dynamic) depending on the se lected mode. The
goal is a high level of agility and ability to accel­
erate on curves. The vehicle is very responsive to
steering.

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 .

Intelligent Technology
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped with an Event Data Re­
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa­
tions, such as an airbag deployment or hitting a road obstacle, data that will assist in understand­
ing how a vehicle's systems performed. The EDR
is designed to record data related to vehicle dy ­
namics and safety systems for a short period of
time, typically 30 seconds or less . The EDR in this
veh icle is designed to record such data as :
-How various systems in your vehicle were oper ­
at ing;
-Whether or not the driver and passenger safety
belts were buckled/fastened;
-How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
-How fast the vehicle was traveling.
These data can help provide a better understand­ ing of the circumstances in which crashes and in ­
juries occur. NOTE : EDR data are recorded by your
vehicle only if a non-trivial crash situation occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e .g .,
name, gender, age, and crash location) are re­
corded. However, other pa rties , such as law en­
forcement, could combine the EDR data wit h the
type of persona lly identifying data routine ly ac­
quired during a crash investigation.
To read data recorded by an EDR, specia l equip­
ment is required, and access to the veh icle or the
EDR is needed. In add it ion to the vehicle manu­
facturer, other parties, such as law enforcement,
that have the specia l equipment, can read the in­
formation if they have access to the vehicle or the
E DR .
Some state laws restrict the retrieval or down­
loading of data stored by ED Rs installed in a vehi­
cle for the express purpose of retrieving data af­
ter an accident or crash event without the own ­
er's consent.
124
Audi will not access the EDR and/or simi lar data
or give it to others
-
-un less t he ve hicle owne r (or lessee if the vehi ­
cle has been leased) agrees; or
-upon the offic ial request by the police; or
-upon the order of a court of law or a govern-
ment agency; or
-for the defense of a lawsuit through the jud icial
discovery process .
-Audi may also use the data for research about
veh icle operat ion and safety performance or
prov ide t he data to a third party for research
purposes without identify ing t he specific vehi­
cle or information about the identity of its own­
er or lessee and only after the recorded vehicle
data has been accessed.
Vehicle control modules
Your vehicle is also equ ipped with a numbe r of
electronic cont rol modules for various vehicle
systems, such as engine management, em iss ion
contro l, airbags, and safety be lts.
These elect ronic control modules record data
during normal vehicle operation t hat may be
needed by trained technic ia ns for diagnostic and
repair purposes. The recording capability of these
modules is limited to data (no sound is record ­
ed). Only a sma ll amount of data is actually re­
corded over a very limited period of time, or stor­
ed when a system fault is detected by a control
module . Some of the data stored may relate to
vehicle speed, d irection, or braking, as well as re­
straint system use and performance in the event
of a crash. Stored data can also only be read a nd
down loaded w ith specia l equipment that is di­
rectly connected to the vehicle.
(D Tips
Your vehicle may be equipped w ith Aud i con­
nect. Your use of certain Audi connect fea­
tures requires wire less services that are pro­
vided by a third party wireless telecommuni ­
cations provider. For details regarding how in­
formation obtained through Audi connect is
collected, processed, transmitted, used, and
shared, please see your contract with the
wireless telecommun ications provider .

tion to you.
Service and disposal of safety belt preten­
sioner
The safety be lt pretensioners are parts of the
safety belts on your Audi. Installing, removing,
servicing or repa iring of belt pretensioners can
damage the safety belt system and prevent it
from work ing correctly in a collision .
There are some important things you have to know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
env ironment.
A WARNING
-
Improper care, serv icing and repa ir proce­
dures can increase the r is k of personal injury
and death by preventing a safety be lt preten­
sioner from activating when needed or acti­
vating it unexpectedly:
- T he be lt pretensione r system can be act ivat­
ed only once . If belt pretensione rs have
been activated, the system must be re­
placed.
- Never repair, adjust, or change any parts of the safety be lt system .
- Safety belt systems including safety belt
pretensioners cannot be repaired. Specia l
procedures are required for removal, insta l­
lation and disposal of this system.
- For any work on the safety belt system, we
strongly recommend that you see your au­

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
comb inations not approved by Audi, lower ing the
vehicle, chang ing the stiffness of the suspension,
including the springs, suspension struts , shock
absorb ers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
158
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
i ng when it should .
& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash .
- Never install suspension components that do not have the same performance charac­
teristics as the components origina lly instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Aud i.

Checking and Filling
-If you a re unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified a re not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends , we
recommend that you switch to unblended
fuel.
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engin e
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TI ER Dete rgent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline , please go to the official website
(www .toptiergas .com) .
After an extended per iod of us ing inadequate
fuels, carbon deposit build-ups can rob your
en­
gine of peak performance.
