The rear cross-traffic assist can warn the driver of
a po tential collis ion with approaching cross-traf­
fic when driving in reverse . Within its limits, the
system monitors the areas behind and next to
the vehicle using the radar sensors when leaving
a parking space

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

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
sport mode is sw itched on . T he driving
wheels co uld spin and the vehicle cou ld
swerve, espec ially on s lick o r sli ppery roa d
surf aces.
- T here is no vehicle stabilization when ESC/
ASR a re swi tched off .
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.
153

Intelligent Technology
CJ) Note
- Neve r let the brakes "rub" by pressing the
pedal light ly when bra king is not actually
necessary. This causes the brakes to over­
heat and increases braking d istance and
causes wear .
- Before driv ing downhill a long distance on a
steep hi ll, decrease your speed and select a
l ower gear. This makes use of the engine
b raking effect and re lieves the brakes . If
you need to b rake additionally , brake in in­
te rvals and n ot co nti nu ously .
(J) Tips
-If the b rake booster is no t wo rking, you
must press the brake pedal with much more
fo rce th an norma l.
- If you re trofit you r vehicle with a fron t spoil­
e r, whee l cove rs o r similar items, ma ke sure

greater than the amount being generated in or­
der to maintain an optimal vehicle battery charge
level.
(D Tips
- Energy management cannot overcome the laws of physics. Note that the charge level
and length of the vehicle battery life are
limited.
- When the starting ability is endangered, the
(•j indicator light turns on ¢ page 30.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when driving short distances, during city driving,
and at cold times of the year. A lot of energy is
used but little is generated. It is also critical
when the engine is not running but electrical
equipment is switched on. In this case, energy is used but none is generated .
In situations like this, energy management will
actively regulate the distribution of energy.
Long periods without use
If you do not drive your vehicle for several days or
weeks, electrical equipment is gradually scaled
back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time. Some convenience functions,
such as interior lighting or power seat adjust­
ment, may not be available under certain circum­
stances . These convenience functions will be
available again once you switch the ignition on
and start the engine.
With the engine switched off
The vehicle battery will drain if you use Infotain ­
ment functions such as listening to the radio
while the engine is switched off .
If the vehicle's ability to start may be impaired by
the energy use, a message will appear in the In­
fotainment system display. The message indi­
cates that the system will switch off automatical-
156
ly soon. If you would like to continue using the
functions, you must start the engine.
With the engine running
Although electrical energy is generated while
driving , the vehicle battery can drain. This can
happen if little energy is generated but much is
used, and the charge level of the vehicle battery
is not optimal.
To restore the balance of energy, components
that require large amounts of energy are tempo­
rarily scaled back or switched off . Heating sys­
tems in particular require a great deal of energy. If you notice, for example, that the seat heating*
or rear window defogger is not working, then it
has been temporarily reduced or switched off.
T hese systems are available again as soon as the
energy supply has been restored.
In addition, you may notice that the idle speed has slightly increased. That is normal and no
cause for concern . By increasing the idling speed,
the additional required energy will be generated
and the vehicle battery will be charged.
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
vehicle is designed to record such data as:
- How various systems in your vehicle were oper­ ating;
- 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,
