Parking systems
General information
A ppl ies to: ve hicles w ith parking system plus/rearview cam ­
era
Depending on your vehicle's equipment , various
parking aids will help you when parking and ma­
neuvering.
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 147.
The rearview camera shows the area behind the
vehicle in the Infotainment system display. This display assists you when you are cross or parallel parking. The parking system plus functions are
also available ¢
page 148.
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 pay attention to the area around the
vehicle -us ing the rearview mirror, too.
-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.
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
146
-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.
(D Tips
-T he 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 shou ld be good light and weath­
er conditions.
-You can change the volume and pitch of the
signals as well as the display¢
page 150.
-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
Electronic Stabilization Control ( ESC) supports
driver safety . It reduces the risk of slipping and
improves dr iving stability. ESC detects critica l sit­
uations such as the vehicle oversteering and un­
dersteer ing or the wheels are spinning. The vehi­
cle is stabilized by apply ing the brakes or reduc ­
ing engine torque . When the ESC engages, the
G1 indicato r light b links in the instrume nt clus­
ter.
The follow ing systems are integrated in the ESC:
Anti-loc k bra king system (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 .
Brake a ssist system
The brake assist system can decrease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold the brake pedal
u nti l the dangerous sit uat io n is ove r. In veh icles
with adaptive cr uise contro l*, the bra ke assist
s ys tem is more sensitive if t he d istance detec ted
to the veh icle dr iv ing ahe ad is too small.
Anti -slip regulation (ASR)
ASR reduces eng ine power when the drive wheels
begin spinning and adapts the force to the road
conditions . This makes i t eas ie r to sta rt, acceler­
ate and dr ive up hill s.
Electronic differential lock (EDL )
The EDL applies the brakes to a wheel that starts
spinning and transfers t he drive power to the
other driving wheel or wheels ( if the veh icle is
eq uipped w ith all whee l dr ive*) . T his function is
n o t available at higher speeds.
Intellig ent Technology
In extreme cases, ED L automat ica lly switches off
to keep the brake o n the braked whee l from over­
heating. The veh icle is still working correct ly. EDL
will switch on again automatically when condi­
t ions have returned to normal.
Ste ering recommendation
The ESC he lps to s tabilize the vehicle by changing
the steering torque.
Select ive wheel torque control
Se lective wheel to rque cont rol is used w hen driv­
i ng on curves. The fron t whee l on the inside of
the curve or bo th wheels on the i nside of the
c u rve are braked se lective ly as needed . This al­
l ows more precise driving in c urves.
Automatic post-collision braking system
T he "automat ic pos t-collision braking system"
c an help to reduce the risk of sliding an d of addi ­
tiona l co llisions a fter an acciden t. If the ai rbag
contro l modu le detects a co llision above a certain
vehicle speed, the veh icle is bra ked by the ESC.
T he vehicle does not bra ke autorn,;1tically if;
- t he dr ive r presses the acce le rator pedal, or
- the ESC, the brake system or the veh icle elect ri-
cal system are not functioning .
A WARNING
-The ESC and its integ rated systems cannot
overcome the lim its imposed by natura l
phys ic al laws. This is especially important
on sli ppery or wet roads . If the sy stems be­
gin acting to stabilize your 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 n ote the r isk of a coll is ion increases
when dr iv ing fast, especially t hrough curves
a nd on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems ca nnot always pre­
vent collisions
-there is st ill a ris k of ac ci-
dents!

Intelligent Technology
- Press the accelerator pedal carefully when
acce le rating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and th is can affect driving stability and
increase the risk of a co llision . condition
. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de ­
scribed are working .
@ Tips
-The ABS and ASR only function correctly
when all four whee ls have a s imilar wear

Brakes
New brak e pad s
New brake pads do not achieve their full braking
effect during the first 2S0 mi (400 km) . They
must be "broken in" f irst. However, you can com­
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in per iod.
Wear
B rake pad
wear depends largely on the way the
veh icle is driven and on operat ing cond itions.
This is especially true if you are driving frequently
in the c ity and on curves or with a sporty driving
style.
Operat ing no ise
Noises may occur when braking depending on the
speed, braking force and outs ide cond itions such
as temperature and humidity .
Effect of wat er and road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight con ­
densation 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
"dr ied" first w ith a few careful brake applica­
tions .
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the brake
rotors for a short amount of time. Th is action,
which is not felt by the d river , happens at regular
Intellig ent Technology
interva ls and ensures a better reaction time for
the brakes in wet weather.
T he brak ing effect ca n also be reduced if yo u are
driv ing on sal ted roads and yo u do not app ly the
brakes for long per iods o f time. The layer o f salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosion
Leav ing the veh icle pa rked for long periods of
time, low mileage and avoiding heavy b raking
can contribute to corrosion on the brake roto rs
and to dirty brake pads .
If you usua lly avoid heavy bra king or if there is
corrosion present, occasiona l heavy brak ing at
high speeds is recommended to clean the brake
rotors and
pads ¢,& .
Brake system malfunction
If you notice that the bra ke pedal travel has sud ­
denly inc re ased, then a br ake circuit in the dua l­
c ircuit b rake system may have malfunctioned.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediate ly 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 pedal harder.
L o w bra ke fluid le ve l
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level is electronically monitored.
Brake bo oster
The brake boos ter amplifies the p ressure you ap ­
ply to the brake pedal. It on ly operates whi le the
engine is running or when the ignition is switched
on (p lug-in hybrid dr ive*) .
A WARNING
-Only app ly 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.

Offroad vehicle?
Your Audi is not an offroad vehicle -th ere is not
enough ground clearance . For this reason, avoid
d ifficult terrain.
& WARNING
- Also, in vehicles with all wheel drive, adapt
your driv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into taking risks,
because th is increases the r isk of an acci­
dent .
-The braking ability of your veh icle is limited
to the tract ion of the wheels . In this way, it
is not diffe rent from a two whee l dr ive vehi­
cl e. Do not be tempted to accelerate to a
high speed when the road is slippe ry, be­
cause this increases the risk of an accident.
-Note that on wet streets, the front wheels
c an "hyd roplane" if dr iving at speeds that
are too high . Unlike front whee l drive
vehicles, the eng ine does not rev higher su d­
denly when the vehicle begins hyd roplaning .
For this reason, adapt your speed to the
road conditions to reduce the risk of an acc i­
dent .
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine .
When a ve hicl e w ith a co nventional energy sys­
tem is not d riven for a long time, the vehicle bat­
tery is dra ined by equipment (for example, the
immobilizer). In certain circumstances, there
could may not be enough energy to start the en­
g ine.
Your veh icle is equipped with an inte lligent ene r­
gy managemen t system for d istr ibuting electrici ­
ty. This significantly improves the starting ability
and inc reases t he vehicle battery life.
Intellig ent Technology
The ene rgy management system Is made up o f
battery diagnosi s, idling cu rrent management ,
and dynamic energy management .
Battery diagnosis
T he battery diagnos is determines the vehicle ba t­
te ry c harge level. The sensors de termine the bat­
te ry vo ltage, the batte ry cu rrent, and the batte ry
temperat ure. The cur rent charge level and the
performa nee of the vehicle battery a re deter ­
mined based on this.
Idling current management
T he idling cur rent management decreases the
energy used while parked . With the engine
switched off, it ma nages the energy distribution
to the d ifferent e lectr ica l components . Data from
the battery d iagnosis is taken into account for
th is.
Depending on the vehicle battery charge level,
electr ical eq uipment is switched
off one item af­
ter the other to prevent the vehicle battery from dra ining and to ma intain the starting ab ility .
Dynamic energy manag ement
While driving, dynamic ene rgy management dis ­
t ributes the appropr iate amo unt of energy to the
electrical eq uipment. It contro ls the battery
charge level so that the amount of energy is not
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 veh icle bat tery life are
li m ited.
