A WARNING
-Pay attention to traffic and the area around
your vehicle when night vision assist is switch­
ed on. The driver is always responsible for as­
sessing the traffic situation.
- Night vision assist can only warn about peo­
ple and wild animals located within the visu­
al range of the infrared camera. The visual
range corresponds to the image in the in­
strument cluster display.
- Night vision assist may not detect people or
wild animals and mark them if
- they are not in an upright position, for ex­
ample if they are sitting or lying down
and/or
- the silhouette in the display appears in­
complete or interrupted, for example be­
cause the person is partially covered by a
parked vehicle or an animal is covered by
tall grass. This could increase the risk of
an accident.
- Never try to swerve around animals if doing
so will endanger you or other road users, be­
cause this increases the risk of an accident.
(I) Tips
- Even though the system evaluates the
shape and heat given off by all detected ob­
jects, there are limits to the system . There
may be false warnings.

A WARNING i-==
- 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 impa ired as a result.
138
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.
{i) 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 146.
- Please refer to the instructions for towing a
trailer located in
¢page 147.
- What appears in the infotainment display is
somewhat time-delayed.
- Th e sensors must be kept clean and free of
snow and ice for the parking aid to operate .

Electronic stabilization
control (ESC)
Description
Elect ronic stabilization control (ESC) supports
driver safety.
It red uces the risk of slipping and
improves driving stability. ESC detects crit ica l sit­
uations such as when the vehicle is oversteering
and understeering or the wheels are spinning.
The vehicle is stabilized by applying the brakes or reducing eng ine torq ue. When the ESC engages,
the
DJ ind icator light blinks in the instrument
cluste r.
The fo llow ing systems are integrated in the ESC:
Ant i-loc k bra king system (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A puls ing in the
brake pedal indicates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis­
tance . It increases braking power when the driver
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold the b rake pedal
until the dangerous situat io n is over . In veh icles
with adapt ive cr uise control*, the bra ke assist
sys tem is more sensitive if the d ista nce detec ted
t o the vehicle dr iv ing ahead is too small.
O n ve hicles w ith act ivated and funct io ni ng night
vision assist*, the brake ass ist system ca n re­
spond more sens it ively if there is a warning.
Anti-Slip Regulation (ASR )
ASR reduces eng ine power when the drive wheels
begin spinning a nd adap ts the force to the road
conditions . This makes it easie r to start, acceler­
ate and dr ive up h ills.
Electron ic differential lock (EDL )
EDL applies the brakes to a wheel that starts
spinning and transfers the drive power to the
148
other driving whee ls. This function is not avai la ­
ble at higher speeds.
In extreme cases , ED L automat ica lly swi tches off
to keep t he b rake on 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.
Steering recommendat ion
The ESC he lps to stabilize the vehicle by chang ing
t h e s teer ing torque.
Select ive wheel torque control
Se lective wheel to rque cont rol is used when d riv­
i ng on curves. Braking is targeted toward the
whee ls on the inside of the curve as needed . T his
a ll ows mo re precise dr iving in cu rves .
Automatic post -collision braking system
The "automat ic post -collis io n braking system"
can help to reduce the risk of sliding and of addi­
tiona l co llisions after an acc ident. If the a irbag
contro l modu le detects a collision, the veh icle is
braked by the ESC.
The veh icle does not brake automatically if:
- the driver presses the accelerator 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 natura l
phys ical laws . This is espec ially important
on s lippery or wet roads . If the systems be­
gi n ac ting to stabilize yo ur vehicle, you
should immediately a lter 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 risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent co llisions -there is st ill a risk of acci­
dents!

Hill descent assist
Hill descent assist makes it possible to drive
down a hill at a constant speed.
Fig. 155 Center console: hill descent ass ist button
.. To switch hill descent assist on, press the 1-

button. The LED in the button turns on.
.. Press the button again to switch it off. The LED
in the button turns off.
Hill descent assist brakes all four wheels auto­
matically in order to limit speed when driving ei­
ther forward or reverse on hills with a grade from approximately 6 to 60%. The wheels w ill not lock
up because the ABS remains activated.
When hill descent assist is on, the speed your ve­
hicle was traveling when it entered the hill is maintained. The assist begins shortly after you
start driv ing and continues up to approximately
19 mph (30 km/h). The driver can increase or de­
crease the vehicle speed w ith in these limits by
pressing the accelerato r or brake pedal.
H owever, there must be enough traction. Hill de­
scent assist
cannot function as expected, if for
150
example the hill is icy or if the surface is loose
~ & .
Active regulat ion of a speed up to approximately
19 mph (30 km/h) is signaled in the instrument
cluster by an indicator light •. T he indicator
light turns on when in the ready mode.
II.
The system does not work at speeds above ap­
proximately 19 mph (30 km/h). The system is
then in ready-mode . This is indicated by the LED
in the button turning on.
Hill descent assist is automatically activated un­
der the following conditions:
- the LED in the button turns on
- the vehicle speed is lower than 19 mph (30 km/
h)
-the hill angle is at least approximately 6%
_&. WARNING
-
- Always adapt your speed to the weather,
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks, because this increases the risk
of an accident.
- The hill descent assist system cannot over­
come the laws of phys ics. Your driving style
must always be adapted to the current road
and traffic cond itions .
- Hill descent assist may not be able to hold
your vehicle at a constant speed under all
conditions while driving on a hill (for exam­
ple if ground under the vehicle is loose).
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" first. However, you can com­
pensate for the slightly reduced braking force by
pressing f irmly on the brake pedal. Avo id heavy
braking during the break-in period.
Wear
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions .
This is especially true if you are driv ing frequent ly

turned o n, the br ake p ads press against the br ake
r otors for a short amoun t of time . This action,
which is not felt by the driver, happens at regular intervals and ens ures a better reaction time for
the brakes in wet weather.
The braking effe ct can also be reduced if you are
d riving on salted roads and you do not apply t he
brakes for long periods of time . The layer of salt
on the bra ke rotors and pads must be worn off
f irst when the brakes are app lied.
Cor rosion
L eaving the vehicle par ked for long pe riods of
time, low mi leage and avoiding heavy braking
can cont ribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avo id heavy b raking or if there is
corrosion present, occasional heavy braking at h igh speeds is recommended to clean the brake
rotors and pads¢

Brake system malfunct ion
If yo u no tic e th at the brake peda l travel has sud­
denly
increased, then a brake c ircuit in the dual­
circuit brake system may have malfunctioned. Drive to an aut ho rized Aud i dea le r or a uth orized
Aud i Service Facility immediately to have the
problem corrected. On the way there, drive with
reduced speed and keep in mi nd that you w ill
need a longer dista nce to stop and you w ill need
to p ress the b rake pedal harde r.
Intellig ent Technology
Low brake fluid level
When the br ake fluid level is low, malfu nctions in
the brake system may occur . The brake fluid level
is electronically monitored .
Brake booster
The brake booster ampl ifies t he p ress ure you ap­
ply to the brake pedal.
A WARNING
- Onl y ap ply the bra kes for the purpose o f
cleaning the brake sys tem when road and
traffic conditions permit. You must not en­
danger other roa d users . This increases the
risk of an accident.
-
- Never let the ve hicle roll while the engine is
stopped because this increases the risk of an
accident.
(D Note
- Never let the brakes "rub" by pressing the
peda l lightly when braking is not actually
necessary. This causes the b rakes to over­
heat and increases braking distance and
causes wear.
- Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear . This makes use of the engi ne
bra king effec t and relieves the brakes. If
you need to bra ke ad ditio na lly, bra ke in in­
t erva ls and not continuously.
(D Tips
- If the brake boos ter is not work ing , you
must press t he b rake peda l w ith much more
force than normal.
- If you retrofit your vehicle with a front s po il­
er, wheel covers or sim ila r i tems, make su re
t ha t the air flow to the fro nt wheels is n ot
i nt errup ted. Otherwise t he b rake system
c an become too hot .
