Parking systems
General information
Applies to vehicles: with rea r parking sys te m s/park in g system
p lus/rearview camera
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 116.
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 116.
The rearview camera shows the area behind the
vehicle in the MMI display. This display assists
you when you are cross or parallel parking. The
parking system plus functions are also available
¢page 117.
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 a lways
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 - using 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 become impaired as a re­
sult . Have an authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
- Make sure the sensors are not obstructed by
st ickers, deposits or other materials.
If they
are the sensor function could be impaired .

@ 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 specific surfaces or struc­
tures such as chain link fences or powder
snow
- If you continue driving closer to a low-lying
object, it may disappear from the sensor
range. Note that you will no longer be
warned about this obstacle.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody. The park­
ing system may become impaired as a re­
sult. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
(D 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 for long grass .
- external ultrasonic sources e.g. from
cleaning vehicles.
- heavy rain, snow, or thick vehicle exhaust.
- 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 weather
conditions.
- You can change the volume and pitch of the
signals as well as the display¢
page 121 .
-What appears in the MMI display is some­
what time-delayed.
- The sensors must be kept clean and free of
snow and ice for the park assist to operate .

Electronic stabilization
control (ESC)
Description
The E lectronic Stabilization Contro l (ESC) reinfor­
ces driver safety. It reduces the risk of slipping
and improves driving stability. ESC detects criti ­
cal s ituations such as the vehicle oversteering
and understeering or the wheels a re spinning.
The vehicle is stabilized by applying the brakes or
reducing engine torque. Once the ESC is activat­
ed, the indicator light
DJ blinks in the instru­
ment cluster.
The fol low ing systems a re integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
i ng. The vehicle can still be steered even during
hard braking . Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal ind icates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking d is­
tance . It increases braking power when the driver
presses the brake pedal quickly in emergency s it­
uations. You must press and hold the brake pedal
unti l the dangerous sit uation is ove r. In vehicles
with adaptive cruise control *, the brake assist
system is more sensit ive if the distance detected
to the vehicle ahead is too small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive whee ls
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up inclines.
Intelligent Technology
Electronic differential lock (EDL)
The EDL brakes whee ls that are spinning and
trans fers the drive power to the other drive wheel
or whee ls if the vehicle is equipped with all wheel
drive*). This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over ­
heating. The vehicle is still working correct ly. EDL
will switch on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
Selective wheel torque control
Selective wheel torque control is used when dr iv­
i ng on curves. The front wheel on the inside of
the curve o r both wheels on the inside of the
curve are braked selectively as needed . This al­
lows more precise driving in curves .
Automatic post-collision braking system
The "Automat ic post -collision braking system"
can help to reduce the ris k of sliding and of other
collisions after an accident. If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
T he vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the brak ing force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electr i­
cal system are not funct ion ing .
A WARNING
-The ESC and its integrated systems cannot
overcome the limits posed by natural phys i­
cal laws. This is especially important on slip­
pery or wet roads .
If the systems begin act­
ing to stabilize your vehicle, you should im-
mediately a lter your speed to match the ..,.

A WARNING
You should only switch sport mode on or switch ESC/ASR off if your driving ab ilities and
road condit ions perm it.
- The stabilization function is limited when
sport mode is switched on. The dr iving
wheels could sp in and the veh icle could
swerve, especially on slick or slippery road
surfaces.
- There is no vehicle stabilization when ESC/
ASR are switched off.
(D Tips
- ESC/ASR cannot be switched off or sport
mode cannot be sw itched on if the cru ise
control system* or the adapt ive cruise con­
trol* is switched on.
- Malfunctions in the Audi magnetic r ide may
make it impossible to sw itch the ESC/ASR
off or to switch spo rt mode o n.
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" f irst. Howeve r, you can com­
pensate for the slightly reduced braking force by
press ing firmly on the b rake pedal. Avoid heavy
braking during the break -in period.
Wear
Brake pad wear is large ly dependent on the way
the veh icle is d riven and on operating co nditions.
This is especially t rue if you are driving frequent ly
in the city and on cu rves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, b rak ing force and o utside conditions s uch
as tempe rat ure and h umid ity.
Effect of water and road s alt
In certain situat ions, for example after driving
throug h wate r, in heavy ra in, after overn ight con­
densat ion or afte r wash ing you r car, the braking
In te llig ent T echnolog y
effect can be reduced by moisture or ice on the
brake rotors and brake pads . The brakes must be
"dried" first with a few careful brake applications.
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the b rake
rotors for a short amount of time . This action
wh ich is not felt by the driver happens at regular
intervals and facilitates a better reaction t ime for
the brakes in wet weather.
The braking effect can a lso be reduced if you are
driv ing on salted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first whe n the brakes a re applied .
Corro sio n
Leav ing the ve hicle parked for long periods of
t ime, low mileage and avoiding heavy braking can
contribute to corros ion on the brake rotors and
dirty brake pads.
If you usua lly avoid heavy b raking or if there is
corrosion present, occas ional heavy braking at
high speeds is recommended to clean the brake
rotors and pads¢,&.
Brake sy stem malfunct ion
if you notice that the b rake pedal travel has sud­
denly gotten larger, then a brake circ uit may have
failed. Drive to an authorized Audi dealer or au ­
thori zed Audi Service Facility immediately to have
the problem cor rected. On the way there, dr ive
with reduced speed and keep in mind that a long
braking distance and increased pressu re on the
brake pedal will be necessa ry.
Low br ake fluid level
When the brake f lu id level is low, malfunct ions in
the brake system may occur. The brake flu id leve l
is electronically mon itored.
Brake boo ste r
The brake booster amplifies the pressure yo u ap­
ply to the brake peda l.
It only works when the en-
gine is running.

Intelligent Technology
& WARNING
-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 compensate for the slight·
ly reduced braking force by pressing firmly
on the brake pedal. Avoid heavy braking dur·
ing the break-in period.
- Alway apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en·
danger other road users. This increases the
risk of an accident.
- On steep slopes , reduce the speed and se­
lect a lower gear or lower selector lever po·
sition. Drive as little as possible while press· ing the brake pedal and avoid putting your
left foot on the brake pedal while driving.
This could cause the brakes to overheat and impair the efficiency of the brakes .
- Do not let the brakes "grind" by always
keeping your foot on the brake pedal. This
can cause the brakes to overheat, increase
wear and increase braking distance unneces·
sarily.
- Certain weather and operating conditions
such as driving through water, driving in
heavy rain or driving after washing your
ve·
hide can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these components by braking carefully. Ap·
plying the brakes carefully several times
dries the brakes and removes ice build-up .
- The efficiency of the brakes can also be im·
paired by driving for long stretches on roads
covered with salt without using the brakes.
You can
remove salt deposits from the brake
rotors and pads by carefully applying the
brakes several times.
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are ventilated properly . Otherwise,
the brake system could overheat, which re·
duces their effectiveness.
- Failure of a brake circuit impairs braking
performance, which increases braking dis·
126
tance. Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident .
-If the brake booster is not working, you will
have to press much harder on the brake ped·
al to compensate for the lack of the booster .
(D Note
-Never let the brakes "rub" by pressing the
pedal lightly when braking is not really nee·
essary. This causes the brakes to overheat
and increases braking distance and causes
wear .
- Before driving on a long stretch with steep
slopes, reduce your speed and shift to the
next lower gear This makes use of the en·
gine braking effect and relieves the brakes .
If you need to brake additionally, brake in
intervals and not continuously.
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force then normal.
- If you retrofit your vehicle with a front spoil·
er, wheel covers or similar items, make sure
that the air flow to the front wheels is not
interrupted. Otherwise the brake system
can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements .
Power steering adapts electronically based on
the vehicle speed.
T he vehicle still has full steering functionality if
the power steering fails or when the engine is
stopped (towing). To steer, you must apply much
more force than usual.

Intelligent Technology
All wheel drive (quattro)
Applies to vehicles: with all w heel drive
In all wheel drive, all four wheels are powered.
General information
In all wheel dr ive, the dr iv in g power is divided be­
tween all four whee ls . T his happens automatical­
ly depending on your driving behavior as well as
the current road conditions . Refer to¢
page 123,
Electronic stabilization control (ESC).
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow ­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­ cautions
q ,& .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
braking effect .
Snow chains
If
there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
q page 230, Snow chains.
Replacing tires
For vehicles with all wheel d rive, only wheels wi th
the same rolling circumference should be used.
Avoid wheels with different tread depths
qpage 221.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terra in. Refer to¢
page 259.
_& WARNING ~
-Also, in vehicles with a ll wheel drive, adapt
your driving style to the current road and
traffic cond itions . Do not let the increased
safety provided tempt you into taking risks.
- The braking ability of your veh icle is limited
to the tract ion of the wheels. In th is way, it
127

Intelligent Technology
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery th is in­
creases the r isk of an accident.
- Note that on wet streets, the front wheels
can "hydrop lane" if driving at speeds that
are too high . Unlike front whee l drive
vehicles, the engi ne does not rev higher sud­
denly when the vehicl e begins hyd rop laning.
Fo r th is r easo n, pay a ttent ion to the road
co ndi tions regardless of your speed.
Energy management
The starting ability is optimized
The en ergy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a ve hicle with a co nventional energy sys­
tem is not driven for a long time, the battery is
drained by equipment (for example the immobil­
izer) . In certa in circumstances , there cou ld may
not be eno ugh energy to start the engine .
Your vehicle is equipped w it h an intelligent ener­
gy management system for distr ibut ing electric i­
ty . T his sign ificantly improves the starting ability
and inc reases the battery life .
The energy management system Is made up of
battery diagnos is , idling cu rrent management
and dynamic energy management.
Battery diagnosis
The batte ry diagnosis determines the batte ry
charge leve l. The sensors determine the batte ry
voltage, the battery current , and the battery
t emperature . The current cha rge level and the
pe rformance of t he battery a re dete rmined based
on this .
Idling current management
The idling cu rrent management decreases the
energy used while parked. W it h the engine
sw itched off, it manages the energy d istribution
to the different electrical components . Date from
battery diagnosis is taken into account for this .
128
Depend ing on the ba tte ry charge leve l, electrical
equipment is switched off one item after the oth­
er, to prevent the battery from dra ining and to
retain the start ing ability.
Dynamic energy management
While driv ing, dynam ic ene rgy management dis­
tribu tes the appropriate amount o f energy to the

What you should know
Maintaining the starting ability is the highest
priority.
A lot of st ress is placed on the battery when dr iv ­
ing sho rt distances, in traffic, and at cold t imes
of the year. A lot of energy is used but little is
generated.
It is also critical when the engine is
not ru nning but e lectr ica l equipment is sw itched
o n. In th is case, energy is used but none is gener ­
ated.
In sit uat ions like this, e nergy ma nagement w ill

Long periods without use
If you do not drive your vehicle for several days or
weeks, e lectr ica l cons umers are grad ually scaled
back or sw itched off. This reduces energy use and
ensures the ve hicle w ill be able to start after long
per iods of time . Some conven ience functions
