Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Re corder
This vehicle is equipped wi th an Event Data Re ­
corder (EDR) . The main purpose of an E DR is to
record, in certain crash or near crash -like situa­
tions, such as an airbag deploym ent or h itting a
road obstacle, data that will assist in understand­
ing how a veh icle 's systems performed . The EDR
is designed to record data related to veh icle dy­
namics a nd safety systems for a sho rt period of
time, typically 30 seconds or less . The E DR in this
veh icle is designed to reco rd s uch data as :
- How various systems in your vehicle were oper­
at ing;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far ( if at all) the driver was depressing the
acce lerator and/or brake peda l; and,
- How fast the ve hicle was trave ling.
These data can help provide a better understand­ ing of the ci rc u mstances in which c rashes and in ­
juries occur. NOT E: EDR data are recorded by yo ur
veh icle only if a non-trivia l crash situat ion occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e .g .,
name, gender, age, and crash location) a re re­
corded . H owever , other pa rties , such as law en­
forcement, cou ld combine the EDR data w it h the
type o f person ally identifyi ng dat a routine ly ac­
qu ired dur ing a crash invest igat ion .
To read data reco rded by an EDR, specia l equip­
men t is req uire d, and access to the veh icle or the
E DR is needed. In ad dition to the vehicle manu­
facturer, other parties, s uch a s law enforcement,
that have t he specia l equipment, can read the in­
formation if they have access to the vehicle or the E DR.
Some s tate laws restrict the re trieva l or down­
loading of data stored by ED Rs insta lled in a vehi ­
cle fo r the express purpose of retrieving data af -
158
ter an accident or crash event withou t the own ­
er 's consent.
Audi will not access the EDR and /or sim ilar data
o r g ive it to others -
- unless t he ve hicle ow ner (o r lessee if the vehi­
cle has been leased) ag rees; o r
- upon the offic ial request by the police; or
- upon the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the jud icia l
discovery process.
- Audi may also use the data for research about
veh icle operation and safety perfo rmance or
prov ide the data to a th ird party for research
purposes w itho ut identify ing t he specific vehi­
cle or info rmat ion about the ident ity of its own­
er or lessee and only afte r th e re co rded vehicle
d ata has been a ccessed.
Vehicle control modules
You r vehicle is also equ ipped with a number of
e lectronic cont rol modules for va rious vehicle
syste ms, such as engine ma nagement, em iss io n
contro l, air bag s, a nd safety be lts.
These electronic control modules record data
dur ing norma l vehicle operation t hat may be
n eeded by tra ined techn ic ians for d iagnost ic and
r ep air pur poses. The re cording capab ility of these
modules is lim ited to dat a (no sou nd is recor d­
ed). Only a sma ll amount of data is actually re ­
corded over a very limited period of time, or stor­
ed when a system fault is detected by a contro l
module . Some of the data stored may relate to
vehicle speed, direction, or braking, as well as re­
straint system use and performance in the event
of a crash . Stored data can also only be read a nd
down loaded w it h specia l equipment that is d i­
r ec tly connec ted to the vehicle.
(D Tips
Your vehicle may be e quipped w it h Aud i con­
n ect . Yo ur use of certain Aud i connect fea­

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 crit ical sit­
uations suc h as the vehicle overstee ring and un­
de rs teer ing or the wheels are sp inning. The vehi­
cle is s tabilized by app ly ing the brakes or reduc­
i ng e ngine torque. Once t he ES C i s ac tiva ted, the
indicator light
DJ b li nks in the instrument clus ­
ter .
The fol low ing systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS preve nts the whee ls from lock ing whe n brak­
i ng. The vehicle can s till be steered even during
h a rd brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
bra ke pedal indica tes th at the system is act ing to
s tabili ze the vehicle.
Brake assist system
The brake assist sys tem can decrease braking dis­
tance .
It increases brak ing power when the d rive r
p resses the brake pedal q uic kl y in eme rgency sit­
uations. Yo u m ust press and hold the b rake pedal
u nti l the dangero us si tuati on is over. In ve hicles
with adaptive cruise contro l*, the bra ke assist
system is more sensitive if the d istance detected
to the veh icle ahead is too small.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive wheels
begin spinning an d adapts the force to the road
conditions. This makes it easie r to sta rt, acceler ­
ate and drive up inclines .
Intelligent Technology
Electronic differential lock (EDL)
T he ED L brakes wheels t hat are spi nning and
transfe rs the drive power to the o ther dr ive
whee l or wheels if the vehicle is equ ipped with all
whee l drive *). T his function is not available at
higher speeds.
In extreme cases, ED L automat ica lly swi tches off
to keep the b rake o n the braked whee l from over­
heating. The vehicle is still working correct ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Steering recommendation
T he ESC he lps to s tabilize the vehicle by changing
the steering torque.
Selective wheel torque control
Se lective w heel torque con trol is used w hen d riv ­
i ng on curves. The front whee l on the ins ide of
the curve or both wheels on t he i nsid e of the
c ur ve are braked se lective ly as needed . This al ­
lows more precise driving in c urves .
Automatic post -collision braking system
T he "Automat ic pos t-collis ion braki ng system"
ca n help to reduce the ris k of sliding and of othe r
collisions af ter an a cciden t. If th e ai rbag cont rol
module detects a collision above a certai n vehicle
speed, the vehicle is brake d by the ESC.
T he veh icle does not br ake au tomatic ally if:
- the dr iver presses the acce lera tor pedal, or
- the braking fo rce generated by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the brake system o r the veh icle electri­
cal system are not functioning.
A WARNING
- T he ESC and its i nteg rated systems ca nnot
over come the li mits posed by natu ral physi­
cal laws. This is espe cially impor tant on slip­
pery o r we t roads . If the systems beg in act­
ing to stabilize your veh icle, you should im ­
mediately a lter your speed to match the
road and tra ffic condit ions. Do not let the
increased safety provided tempt you into

0 > co ,...., A WARNING
You should only switch sport mode on or switch ESC/ASR off if your driving abilities
and road conditions permi t.
- The stabilization function is limited when
sport mode is sw itched on . T he driving
w heels could spi n and the veh icle cou ld
swerve, espec ially on s lick o r sli ppery road
s u rf aces.
- T here is no veh icle stabilization when ESC/
ASR a re swi tched off.
(D Tips
- ESC/ASR cannot be switched off or sport
mode cannot be sw itched on if t he cru ise
contro l system* or the adaptive c ruise con­
tro l* is sw itched on .
- Mal functions in the Audi magnet ic r ide may
make it imposs ible to sw itch the ESC/ASR
off or to switc h sport mode on .
Brakes
New brake pads
New brake pads do not ac hieve the ir full braking
effect during the first 250 mi (400 km) . They
must be "b roken in " fi rs t . However, you can com­
pensate for the slightly reduced bra king fo rce by
p ressing firmly o n the brake pedal. Avoid heavy
b raking during the break -in period .
Wear
Brake pad
wear depends largely on the way th e
ve hicl e is driven a nd on operat ing cond itions.
This is especially true if you are d riving frequently
in the c ity and on c urves o r wi th a sporty driving
style.
Operating noise
Noises may occur when bra kin g depend ing on the
speed , braking force and ou ts ide cond it ions s uch
as tempe rature and humidity .
Effect of water and road salt
In certain situations, for example after dr iving
through water, in heavy ra in, after ove rnig ht con­
densat ion or after washing your car, the b raking
Intellig ent Technology
effect ca n be reduced by moist ure o r ice on the
bra ke rotors and brake pads . The brakes must be
"d ried" first with a few caref ul brake applica­
tions.
At h igher speeds and w ith the wi ndshield wipe rs
tu rned on, the brake pads press against the brake
roto rs fo r a short amount of time. This action
wh ich is not felt by the dr iver happens at reg ular
interva ls and facilit ates a be tter reaction t ime for
the brakes in wet weather .
The braking effect can a lso be reduced if yo u are
driv ing on salted roads and yo u do not app ly the
brakes for long per iods of time . The layer of salt
o n the brake rotors and pads must be wor n off
first whe n the bra kes are applied .
Corrosion
Leaving the vehicle pa rked for long periods of
time, 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 brak ing or if there is
corrosion present, occasiona l heavy brak ing at
high speeds is recommended to clean the b rake
roto rs and pads<=>,& .
Brake system malfunction
if you notice that t he b rake pedal travel has sud­
denly gotten larger, t hen a b rake c ircuit may have
failed. Drive to an author iz ed Audi dealer or au­
thorized Audi Serv ice Facility immediately to have
t h e problem corrected. On the way there, drive
with red uced speed and keep in mind that a long
bra king d ista nce and increased pressu re on the
br ak e pedal w ill be necessary.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur . The b rake fluid level
i s elec tronica lly monito red .
Brake booster
The brake booster amp lifies the press ure you ap­
ply to the brake pedal. It on ly operates wh ile the
engine is run ning o r when the ignition is switched
on (p lug-i n hyb rid dr ive*) . .,.

Intelligent Technology
A 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
slightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy brak­
ing during the break-in period.
- Only 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 ­
hicle 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 -
162
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
pedal 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 nec­
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 than normal.
- If you retrofit your vehicle with a front spoil­
er, wheel covers or similar items, make su re
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 .
The 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. .,.

Driver's and front
passenger's footwell
Important safety instructions
Appl ies to vehicles: with knee airbags
8_ WARNING
Always make sure that the knee airbag can in­
flate without interference. Objects between
yourself and the airbag can increase the risk
of injury in an accident by interfering with the
way the airbag deploys or by being pushed in­
to you as the airbag deploys .
- No persons (children) or anima ls shou ld ride
in the footwell in front of the passenger
seat.
If the airbag dep loys, this can result in
serious or fatal injuries .
- No objects of any kind should be carried in
the footwell area in front of the driver's or
passenger's seat. Bulky objects (shopping
bags, for example) can hamper or prevent
proper deployment of the airbag . Small ob­
jects can be thrown through the vehicle if
the airbag deploys and injure you or your
passengers.
Driving safety
Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mat or
any other object.
Make sure that all pedals move freely without in­
terference and that nothing prevents them from
returning to their original positions .
Only use floor mats that leave the pedal area free
and can be secured with floor mat fasteners .
If a brake circuit fails, increased brake pedal trav­
el is required to bring the vehicle to a full stop.
8_ WARNING
--
Pedals that cannot move freely can cause loss
of vehicle control and increase the risk of seri­
ous injury.
- Never place any objects in the driver's foot­
well. An object could get into the pedal area
and interfere with pedal function. In case of
sudden braking or an accident, you would
not be able to brake or acce lerate!
-Always make sure that nothing can fall or
move into the driver's footwell.
Floor mats on the driver side
Always use floor mats that can be securely at­ tached to the floor mat fasteners and do not in ­
terfere with the free movement of the pedals.
.. Make sure that the floor mats are properly se­
cured and cannot move and interfere with the
pedals~ &-
Use only floor mats that leave the pedal area un­
obstructed and that are firmly secured so that
they cannot slip out of position . You can obtain
suitable floor mats from your author ized Audi
Dealer.
Floor mat fasteners are installed in your Audi .
Floor mats used in your vehicle must be attached
to these fasteners . Properly securing the floor

mats will prevent them from sliding into posi­
tions that could interfere with the pedals or im­
pair safe operation of your vehicle in other ways.
A WARNING
Pedals that cannot move freely can result in a
loss of vehicle control and increase the risk of
serious personal injury.
- Always make sure that floor mats are prop­
erly secured .
- Never place or install floor mats or other
floor coverings in the vehicle that cannot be
properly secured in place to prevent them
from slipping and interfering with the ped­ als or the ability to control the vehicle.
- Never place or install floor mats or other
floor coverings on top of already installed
floor mats. Addit ional floor mats and other
coverings will reduce the size of the pedal
area and interfere with the pedals.
- Always properly reinstall and secure floor
mats that have been taken out for cleaning.
- Always make sure that objects cannot fall
into the driver footwell while the veh icle is
moving. Objects can become trapped under
the brake pedal and accelerator pedal caus­
ing a loss of vehicle control.
Storing cargo correctly
Loading the luggage compartment
All luggage and other objects must be properly
s towed and secured in the luggage compart­
ment.
Fig. 150 Safe load pos it io nin g: place heavy objects as low
and as far forward as possible (example) .
172
Loose items in the luggage compartment can
shift suddenly, changing vehicle handling charac­
teristics. Loose items can also increase the risk of
serious personal injury in a sudden vehicle ma­
neuver or in a collision.
.,. Distribute the load evenly in the luggage com­
partment.
.,. Always place and properly secure heavy items in
the luggage compartment as far forward as
possible .
.,. Secure luggage using the t ie-downs provided
~ page 64.
.,. Make sure that the rear seatback is securely
latched in place.
A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serious per­ sonal injury in the event of hard braking or an
accident. To help reduce the risk of serious personal injury:
- Always put objects, for example, luggage or
other heavy items in the luggage compart­
ment.
-Always secure objects in the luggage com­
partment using the tie-down hooks and
suitable straps .
A WARNING
Heavy loads will influence the way your vehi­
cle handles . To help reduce the risk of a loss
of control leading to serious personal injury:
-Always keep in mind when transporting heavy objects, that a change in the center of
gravity can also cause changes in vehicle
handling:
- Always distribute the load as evenly as
possible.
- Place heavy objects as far forward in the
luggage compartment as possible .
- Never exceed the Gross Axle Weight Rating
or the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the left
door jamb. Exceeding permissible weight
standards can cause the vehicle to slide and
handle differently .

Checking and Filling
CJ) Note
-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives with the AdBlue and do not dilute it
with water.
- Only use refill bottles that are approved for your vehicle. Using other systems can cause Ad Blue to leak.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the Ad Blue tank. Do not start
the engine under any circumstances if the
wrong fuel is filled in the tank . There is a
risk of damaging the fuel tank system and
the engine . See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the
Ad Blue has already crystallized, use warm
water and a sponge. AdBlue residue that is
not removed will crystallize and can damage
the affected surface .
- Do not store the refill bottle in the vehicle.
If it leaks, the escaping Ad Blue could dam­
age the vehicle interior .
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa ­
ter .
(D Tips
-You can obtain refill bottles from an author­
ized Audi dealer or authorized Audi Service
Facility .
- Follow the Ad Blue manufacturer's instruc­
tions for use and storage .
- A permitted refill bottle contains approxi­
mately 1.9 liters of AdBlue .
- Ad Blue can freeze at very low temperatures.
If this happens, the system will not detect
that the Ad Blue was refilled and it will con­
tinue to inform you of the low AdBlue level.
The message turns off as soon as the tank
thaws out again.
