-Please note that the sensor does not always
detect all objects. This increases the risk of a
collision.
- Pre sense front does not react to people or
animals or objects that are crossing the ve­
hicle's path or are difficult to detect
¢ page 97.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the funct ion of the radar sensor and
the system's ability to detect a collision risk .
- Lack of attention can lead to collisions, oth­
er accidents and serious injuries. pre sense
front is an assistance system and cannot
prevent a collision by itself. The driver must
always intervene . The driver is always re­
sponsible for braking at the right time.
- Always pay attention to traffic, even when
pre sense front is switched on . Always be
ready to intervene and take over complete
control of the vehicle whenever it is neces­
sary. Always follow traffic laws regarding
maintaining a safe distance between your
vehicle and vehicles ahead.
- pre sense front works within certain limits
and cannot react to situations that are out­
side of the system limits, such as when ap­
proaching a stationary vehicle or a station­
ary obstacle (the end of a traffic jam or ave­
hicle that has broken down).
- Always keep in m ind that the radar sensor
for pre sense front only works w ith in de­
fined detection zones, which means other
vehicles may not always be detected correct­
ly.
- The function and range of the radar sensor
can be impaired by rain, snow and heavy
mist. Vehicles ahead may not be detected
right away, or not detected at a ll.
- Reflective surfaces such as guard rails or en­
trances to tunnels may impair the function
of the radar sensor.
(D Note
The sensor can be disp laced by impacts or
damage to the bumper, whee l hous ing and
underbody. The pre sense front sensor can be
damaged by this . Have an authorized Audi
Assist
dealer or authorized Audi Service Facility
check their function.
(D Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak ­
ing yourself, by acce lerating noticeably or by
swerving .
- For information on driver messages about
pre sense, refer to ¢
page 106.
- Keep in mind that pre sense front can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury .
- Certain pre sense front functions switch
off
when ESC is switched off (sport mode) or
when driving in reverse.
- The pre sense front functions are not availa­
ble if there is a malfunction in the adaptive
cruise control* system

Audi active lane assist
Description
Applies to vehicles : with Audi active lane assist
Active lane ass ist detects lane marker lines with­
in the limits of the system using a came ra in the
windshie ld. If you are app roach ing a detected
lane marker line and it appears like ly 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 steering
wheel will v ibrate light ly. In order for this warn­
ing vibrat ion to occur, it must first be switched
on in the MMI. Active lane assist is operable
when the lane marker line is detected on at least one side of the veh icle.
l) T hi s function is not ava ilable in all cou ntri es.
106
The system will not warn you befo re crossing a
l ane marker line if you have activated the turn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
The system is des igned for driving on express ­
ways and highways and therefore on ly activates
at speeds above approx imately 40 mph (65 km/
h).
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 you r hands on the steering
wheel.
- Corrective steer ing may not occur in certa in
situa tions, su ch as during heavy braking.
- There may be cases where the camera does
not recognize all lane ma rker lines. Correc­
tive stee ring can only take p lace on the side
of the vehicle where lane marker line5 are
detec ted.
- Othe r road structures or obje cts cou ld possi­
b ly be identified un intent ionally as lane
marker l ines . 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 rain,
snow, heavy spray light shining into the
camera or by d irt on the window. This can
result in active lane ass ist not detecting the
lane marker lines or detecting them incor­
rectly.
- In certain situat ions where visibility is low,
the vehicle may switch from "early" to "late"
corrective steering
l l.
- Under certain co nditions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steering a lone may not be enough
to keep the vehicle in the midd le of the lane.

· Description
Applies to vehicles: with Audi drive se lect
The vehicle setup in each mode depends on the
vehicle's features. However , the eng ine and steer­
ing are always affected.
Engine and automatic transmission
Depending on the mode, the engine and auto­
matic transmission* respond more qu ickly or in a
more balanced manner to accelerator peda l
movements .
Adaptive dampers (Audi magnetic ride)*
The adaptive dampers use sensors to record in ­
format ion regarding steer ing movements, brak­
ing and acce lerat ion operations by the driver,
road surface, dr iv ing speed, and load. With Audi
drive select you can adjust the adaptive dampers
sporty (dynamic), comfortable (comfort) or bal­
anced (auto).
Steering
T he steer ing adapts in terms of steer ing ass is­
tance. There a re diffe rent modes
Q page 113.
Indirect steering that moves easily as in comfort
mode is especia lly suited to long drives on a high ­
way. The dynamic mode provides sporty, direct
steering .
For vehicles with progressive steering* the steer­
ing performance is more agi le .
Cornering light*
The cornering light adjusts when driv ing on
curves at speeds between 6 mph (10 km/h) and
68 mph (110 km/h). The pivoting action and the
lig hting are also adapted to the mode.
Adaptive cruise control*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
Audi drive select mode. Adaptive cruise control
also responds to the driving behavior of the vehi­
cle ahead in a more conservative or sporty man­
ner.

Depending on your vehicle's equipment, various
parking aids will help you when parking and ma­
neuvering.
The
rear parking system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 116.
The parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the vehicle
¢ page 116.
The rearview camera shows the area behind the
vehicle in the MMI display. This display assists
you when you are cross or parallel parking. The
parking system plus functions are also available
¢page 117.
A WARNING ,--
- Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is a lways
responsible when entering or leaving a park­
ing space and during similar maneuvers .
- Please note that some surfaces, such as
clothing, are not detected by the system.
- Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals .
- Always pay attention to the area around the
vehicle - using the rearview mirror, too.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,

A WARNING
You should only switch sport mode on or switch ESC/ASR off if your driving ab ilities and
road condit ions perm it.
- The stabilization function is limited when
sport mode is switched on. The dr iving
wheels could sp in and the veh icle could
swerve, especially on slick or slippery road
surfaces.
- There is no vehicle stabilization when ESC/
ASR are switched off.
(D Tips
- ESC/ASR cannot be switched off or sport
mode cannot be sw itched on if the cru ise
control system* or the adapt ive cruise con­
trol* is switched on.
- Malfunctions in the Audi magnetic r ide may
make it impossible to sw itch the ESC/ASR
off or to switch spo rt mode o n.
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km). They
must be "broken in" f irst. Howeve r, you can com­
pensate for the slightly reduced braking force by
press ing firmly on the b rake pedal. Avoid heavy
braking during the break -in period.
Wear
Brake pad wear is large ly dependent on the way
the veh icle is d riven and on operating co nditions.
This is especially t rue if you are driving frequent ly
in the city and on cu rves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, b rak ing force and o utside conditions s uch
as tempe rat ure and h umid ity.
Effect of water and road s alt
In certain situat ions, for example after driving
throug h wate r, in heavy ra in, after overn ight con­
densat ion or afte r wash ing you r car, the braking
In te llig ent T echnolog y
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 applications.
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the b rake
rotors for a short amount of time . This action
wh ich is not felt by the driver happens at regular
intervals and facilitates a better reaction t ime for
the brakes in wet weather.
The braking effect can a lso be reduced if you are
driv ing 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
first whe n the brakes a re applied .
Corro sio n
Leav ing the ve hicle parked for long periods of
t ime, low mileage and avoiding heavy braking can
contribute to corros ion on the brake rotors and
dirty brake pads.
If you usua lly avoid heavy b raking or if there is
corrosion present, occas ional heavy braking at
high speeds is recommended to clean the brake
rotors and pads¢,&.
Brake sy stem malfunct ion
if you notice that the b rake pedal travel has sud­
denly gotten larger, then a brake circ uit may have
failed. Drive to an authorized Audi dealer or au ­
thori zed Audi Service Facility immediately to have
the problem cor rected. On the way there, dr ive
with reduced speed and keep in mind that a long
braking distance and increased pressu re on the
brake pedal will be necessa ry.
Low br ake fluid level
When the brake f lu id level is low, malfunct ions in
the brake system may occur. The brake flu id leve l
is electronically mon itored.
Brake boo ste r
The brake booster amplifies the pressure yo u ap­
ply to the brake peda l.
It only works when the en-
gine is running.

& WARNING
-New brake pads do not achieve their full
braking effect during the first 250 mi
(400 km). They must be "broken in" first .
However, you can compensate for the slight·
ly reduced braking force by pressing firmly
on the brake pedal. Avoid heavy braking dur·
ing the break-in period.
- Alway apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en·
danger other road users. This increases the
risk of an accident.
- On steep slopes , reduce the speed and se­
lect a lower gear or lower selector lever po·
sition. Drive as little as possible while press· ing the brake pedal and avoid putting your
left foot on the brake pedal while driving.
This could cause the brakes to overheat and impair the efficiency of the brakes .
- Do not let the brakes "grind" by always
keeping your foot on the brake pedal. This
can cause the brakes to overheat, increase
wear and increase braking distance unneces·
sarily.
- Certain weather and operating conditions
such as driving through water, driving in
heavy rain or driving after washing your
ve·
hide 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·
paired by driving 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.
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are ventilated properly . Otherwise,
the brake system could overheat, which re·
duces their effectiveness.
- Failure of a brake circuit impairs braking
performance, which increases braking dis·

tance. Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident .
-If the brake booster is not working, you will
have to press much harder on the brake ped·
al to compensate for the lack of the booster .
(D Note
-Never let the brakes "rub" by pressing the
pedal lightly when braking is not really nee·
essary. This causes the brakes to overheat
and increases braking distance and causes
wear .
- Before driving on a long stretch with steep
slopes, reduce your speed and shift to the
next lower gear This makes use of the en·
gine braking effect and relieves the brakes .
If you need to brake additionally, brake in
intervals and not continuously.
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force then normal.
- If you retrofit your vehicle with a front spoil·
er, wheel covers or similar items, make sure
that the air flow to the front wheels is not
interrupted. Otherwise the brake system
can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements .
Power steering adapts electronically based on
the vehicle speed.
T he vehicle still has full steering functionality if
the power steering fails or when the engine is
stopped (towing). To steer, you must apply much
more force than usual.
