Audi active Lane assist
Description
Applies to : vehicles wi th A udi act ive la n e ass ist
Active lane ass ist (lane departure warning) de­
tects lane marker lines within the l imits of the
system using a camera in the windshield . If you
are approach ing a detected lane marker l ine and
it appears likely that you will leave the lane, the
system w ill warn you with corrective steering.
You can override this steering at any time. If you pass over a line, the steering whee l will vibrate
lightly . In order for this warn ing v ibration to oc­
cur, it must first be sw itched on in the Infotain­
ment system. Act ive lane assis t is ready for oper­
ation when the lane marker line is detected on at
least one side of the veh icle .
The system is designed for driving on express­ ways and h ighways and therefore only activates
at speeds above approx imately 40 mph (65 km/
h).
Applies to: vehicles with side assist: if you acti­
vate a turn s ignal when active lane assist is ready
and it classifies a lane change as critical because
of vehicles traveling alongside you or approach­ i n g you, the re w ill be noticeable corrective steer­
i n g shortly before you leave the lane. This will at­
tempt to keep your veh icle in the lane.
Applies to: vehicles without side assist: the ready
system does not wa rn you if you activate a turn
signal befo re cross ing the lane marker line. In
130
this case, it assumes that you are chang ing lanes
intentionally .
Applies to: vehicles with adaptive cruise control:
there is no corrective steer ing or warnings if the
system recognizes a dist inct passing maneuver .
If the conditions are met, traffic jam assist
switches on at speeds under approximately
40 mph (65
km/h) ¢ page 121.
A WARNING
,-
- The system warns the driver that the vehicle
is leaving the lane using correct ive 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 itse lf . Al­
ways keep your hands on the steering
wheel.
- Cor rective steering may not occur in certain
situations, such as du ring heavy braking.
- There may be cases where the camera does
not recognize all lane marker lines. Correc­
tive stee ring can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Othe r road structures or objects could poss i­
bly be identified un intent ionally 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 rain,
snow, heavy spray or light shining into the
camera. This can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing them incorrectly .
- In certain s ituations where visibility is low,
the vehicle may switch from an "early" to
"late" steering correction .
- Under certain cond it ions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steer ing alone may not be enough
to keep the vehicle in the m iddle of the lane .
- For safety reasons, act ive la ne assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the

potential for hydroplaning. Using active lane
assist under these conditions may increase
the risk of a crash.

or because they are obstructed by snow, dirt,
water or light ing) .
- The vehicle speed is below the activation speed of approximately 40 mph (65 km/h).
- The lane is too narrow or too wide.
- The curve is too narrow.
- The driver's hands are not on the steering

tem plus/rearv iew camera/peripheral cameras
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 142.
T he
parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the vehicle
¢ page 142.
T he
rearview camera shows the area behind the
vehicle in the Infotainment system display . The
lines in the rearview camera image help you to
park or maneuver ¢
page 143. The parking sys­
tem plus functions are also available
¢ page 142.
The
peripheral cameras give various views to
help you when parking or maneuvering
¢
page 145 . The parking system plus functions
are also available
¢ page 142.
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 always
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 keep your eyes on the vehicle's sur ­
roundings, using the rearview mirror as
well.
-The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody . The park­
ing system may be impaired as a result.
Parking systems
Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion.
(D Note
-Some objects are not detected or displayed
by the system under certain circumstances:
-objects such as barrier chains, trailer draw bars, vertical poles or fences
-objects above the sensors such as wall ex ­
tensions
-objects with certain surfaces or structures
such as chain link fences or powder snow
-If you continue driving closer to a low ob­
ject, it may disappear from the sensor
range . Note that you will no longer be
warned about this obstacle.
-Keep enough distance from the curb to re ­
duce the risk of damage to the rims.
(!) Tips
-The system may provide a warning even
though there are no obstacles in the cover ­
age area in some situations, such as:
-certain road surfaces or when there is tall
grass
-external ultrasonic sources such as from
cleaning vehicles
-in heavy rain, snow, or thick vehicle ex­
haust
-We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system. When doing
this, there should be good light and weath­
er conditions .
-You can change the volume of the signals
and the display ¢
page 148.
-Please refer to the instructions for towing a
trailer located in
¢page 149.
-What appears in the infotainment display is
somewhat time-delayed.
-The sensors must be kept clean and free of
snow and ice for the parking aid to operate.

Intelligent Technology Electronic stabilization
control (ESC)
Description
Ele ctronic stabilization control (ESC) supports
driver safety . It reduces the risk of slipping and
improves d riving stability. ESC detects critica l sit ­
uations such as when the vehicle is oversteering
and understeering or the wheels are spinn ing.
T he vehicle is stabilized by applying the brakes or
reducing eng ine torq ue. When the ESC engages,
the
J;,j ind icator light blinks in the instrument
cluste r.
T he follow ing systems are integrated in the ESC:
Ant i-loc k bra king s ystem (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can still be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
b rake pedal indicates that the system is act ing to
stabilize the vehicle .
Br ake a ssist s ystem
The brake assist system can decrease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
unti l the dangerous sit uat io n is ove r. In veh icles
with adaptive cr uise contro l*, the bra ke assist
system is more sensitive if t he d istance detec ted
to the veh icle dr iv ing ahead is too small.
Anti-Slip Regulation (ASR )
ASR red uces eng ine power when the drive wheels
begin spinning and adapts the force to the road
conditions . This makes it easie r to sta rt, acceler­
ate and dr ive up hill s.
Electronic differenti al lock (EDL )
EDL applies the brakes to a wheel that starts
spi nning and t ransfers t he drive powe r to the
;;§ other driving wheels. This f unct ion is not availa-....
~ b lea t higher speeds.
N .... 0 \0
3 Intellig ent Technology
In extreme cases , ED L automat ica lly switches off
to keep the brake o n the braked wheel from over­
heating. The veh icle is still working correct ly. ED L
will switch on again automatically when condi­
tions have returned to normal.
Ste ering recommendation
The ESC he lps to stabilize the vehicle by changing
the steering torque.
In veh icles wi th dynamic steer ing*, ESC also
helps to stab ilize the steer ing in crit ica l sit ua ­
tions.
Selective wheel torque control
Se lective w heel to rque con trol is used w hen d riv­
i ng on curves. Bra king is targeted towa rd t he
whee ls on the inside of the cu rve as needed. This
allows mo re precise driving in curves .
Automatic post -collision braking system
The "automat ic post-collision braking system "
can help to reduce the risk of sliding and of addi­
tiona l co llisions after an acciden t. If the a irbag
contro l
module detects a co llision, the veh icle is
braked by the ESC.
T he veh icle does not bra ke automatically if:
- the dr iver presses the acce lerator pedal, or
- the ESC, the brake system or the veh icle elect ri-
cal system are not functioning.
A WARNING
=
- The ESC and its integrated systems cannot
overcome the lim its imposed by natural
phys ica l laws. This is especially important
on slippery or wet roads. If the systems be­
gin acting to s tabilize yo ur vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the inc reased safety provided tempt
you into taking risks. This could increase
your r isk of a coll is ion.
- Please note the ris k of a collis ion increases
when dr iv ing fast, especially through curves
and on slippery or wet roads, and when dr iv-
ing too close to objects ahead . The ESC and

its integra ted systems cannot always pre­
vent collisions
-there is still a risk of acci­
dents!
- Press the accelerator pedal carefully when
acce lerating on smooth, slippery surfaces
such as ice and snow. The dr ive wheels can
spin even when these control systems are
Switching on and off
installed and this can affect dr iv ing stab ility
and increase the risk of a collision.
@ Tips
- The ABS and ASR only funct ion correctly
when a ll four wheels have a simi lar wear
condition . Different tire sizes can lead to a
red uction in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine.

A WARNING
You should only switch sport mode on or switch ESC/ASR off if your driving abilities
and road conditions permit .
- The stabilization function is limited when

Brakes
New brake pads
New brake pads do not ac hieve the ir full b raking
effect during the first 250 mi (400 km) . They
must be "broken
in " fi rst . However, you can com­
pensate for the slightly reduced bra king fo rce by
pr ess ing firmly o n the bra ke pe dal. Avoid heavy
b ra king dur ing t he b reak -in per io d .
Wear
Brake pad wear depends largely o n the way the
ve hicl e is driven and on operat ing cond it ions .
This is especially t rue if you are d riving freque ntly
in t he c ity and on curves o r wi th a sporty driving
s tyle.
Operating noise
Noises may occur when braking depend ing o n the
speed , braking force and ou ts ide cond it ions such
as te m pe ra ture and humi dity .
Wet conditions or road salt
In certain situations, for example after driving
through water, in heavy ra in or after washing
your car, the braking ef fect may be reduced due
to mo isture or ice on the b rake roto rs and b rake
pads. The b rakes mus t be
"dried" firs t wi th a few
care ful bra ke app lic at ions.
At higher speeds and with t he windsh ie ld wipers
turned o n, the brake pads press against the bra ke
rotors for a s ho rt amoun t of time. This ac tion,
whi ch is not felt by the driver , happens at regul ar
i nte rvals an d ens ures a better reac tion time fo r
the brakes in wet weat her.
Intellig ent Technology
The brak ing effec t can a lso be reduced if yo u are
driving on salted roads and yo u do not app ly the
bra kes for long per iods o f time. The layer of sa lt
on the brake rotors and pads m ust be worn off
first whe n the brakes are applied .
Corrosion
Leaving t he vehi cle pa rked for long periods o f
time, low mileage and avoiding heavy b raking
can contrib ute to corros ion on the b rake roto rs
and to dirty brake pads.
If you usu a lly avoid heavy bra king or if there is
cor rosion prese nt, occasiona l heavy braking at
high speeds is recommended to clean the brake
roto rs and pads
c> ,& .
Brake system malfunction
If you notice that the bra ke pedal trave l has sud ­
denly in crease d, then a brake circuit in the dua l­
circuit b rake system may have malfunctioned.
Drive to an authorized A udi dealer or authorized
Audi Se rvice Facility immed iate ly to have the
problem corrected. On the way there, d rive w ith
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the bra ke ped al ha rder.
Low brake fluid level
When the bra ke fluid level is low, malfu nctions in
the b rake system may occur . T h e brake fluid level
is e lec tron ically moni tored.
Brake booster
The brake booster ampli fies t he p ressure you ap­
ply to the brake pedal.
A WARNING
- On ly app ly the brakes for the purpose of
cleaning the brake system when road and
traffic cond itions permi t. You must not en ­
da nger other road users. This inc reases the
ris k of an a ccid en t.
- Never let the vehicle roll while the engine is
sto pped bec ause t his increases the risk of an
a ccident.
