F ig. 129 Fro nt o f vehicl e: sensor
T he radar sensor area ¢ fig . 129 mus t not be cov­
ered with st ickers, deposits or any other obstruc ­
tions as it may impair the function of the adap­ tive c ruise control or the pre sense front . For in­
formation on clean ing ,
see ¢ page 347 . The
same applies fo r any modifications made in the
front area .
The funct ion of the adaptive cruise contro l sys­
tem or pre sense fron t is l imited in some cond i­
tions :
- Vehicles can only be detected when they are
within the senso r
range¢ page 126, fig . 128 .
- The system has a limited abil ity to detect
vehicles that are a short distance ahead, off to
t h e side of your vehicle or moving into your
lane .
- Objects that are difficu lt to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not detected at all .
- When driving through curves

Ass is ta nce syst ems
-When the vehicle is stationary ¢ page 128.
A WARNING
Always pay attention to the traffic around you
when adaptive cruise control is switched on.
As the driver , you are still responsible for your
own speed and the d istance to other veh icles .
The adaptive cruise control is used to ass ist
you . The driver m ust always take action to
avo id a co llision . The d river is always responsi­
b le for b raking at the co rrect t ime.
- For safety reasons, do not use adaptive
cru ise control when driving on roads with
many cu rves , when the road s urface is in
poor conditio n and/or in bad wea ther (such
as ice, fog, gravel, heavy rain and hyd roplan ­
ing) . Using the system under these condi­
tions could result in a co llision.
- Sw itch adaptive cruise control off tempora ­
rily when driving in turning lanes, on ex­ pressway ex its or in construction zones . This
prevents the veh icle from acce lerating to
the stored speed when i n these situat ions.
- The adaptive cruise contro l system will not
brake by itself if you put you r foot on the ac­
celerator pedal. Doing so can override the
speed and d istance regulat ion .
- Adapt ive cruise control does not respond to
peop le, animals, or crossing or oncoming
objects .
- The funct ion of the radar sensors can be af­
fected by reflective objects such as gua rd
rails, the en trance to a t unnel, heavy rain or
ice .
(D Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and underbody. This can impair the adaptive
cruise control. Have an authorized A udi dealer
o r authorized Audi Service Facility check t heir

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 .

Parking system plus
Description
Applies to: vehicles with parking system plus
Parking system plus provides audio and visual
signals when parking.
Fig. 151 Illustrat ion:
Sensors are located in the front and rear bump­
e rs. If these detect an obstacle, audible and visu­
al signa ls warn you.
Make sure the sensors are not covered by stick­
ers, deposits or any other obstructions as it may
impair the function of the system. For informa­
tion on cleaning, see
¢ page 347.
The display field begins approximately at:
® 4 ft (1.20 m)
® 3 ft (0.90 m)
© 5.2 ft (1.60 m)
® 3 ft (0.90 m)
The closer you get to the obstacle, the shorter
the interval between the audible signals. A con­
tinuous tone sounds when the obstacle is less
than approximately 1 foot (0.30 meters) away.
Do not continue driving forward or in reverse
¢ & in General information on page 146, ¢0 in
General information on page 146!
If the distance to an obstacle remains constant,
the volume of the distance warning gradually
lo wers after a few seconds until it is muted (this
is not apply in the continuous tone range).
If the
obstacle becomes closer than it was before the
gi sound was muted, the tone will sound again. If
~ the obstacle is father away than it was before the
~ sound was muted, no tone will sound . Pay atten-o N > 00

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.
-Whe n the sta rting ability is endangered, the
i•) i n dicator light t urns on r=v pag e 29.
What you should know
Maintaining the starting ability is the highest
priority .
A lot of stress is placed on the veh icle battery
whe n driving short distances, during city driving,
