The selec tor lever is locked in the P and N posi­
tions when the ignit ion is switched on. The re­
move it from these positions , the driver m ust
press the brake pedal and press the lock button
at the same time. The following message ap­
pears in the instrument cluster display when the
selector lever is in the P or N position to remind
the driver:
Press brake to change gear while stationary.
The automatic shift lock only funct ions when the
vehicle is stat ionary o r at speeds be low 1 mph
(2 km/h). At higher speeds, the lock is automati­
cally deactivated in the N position.
The selector lever is not locked when shifting
quick ly through N, for example from R to D. This
makes it possible to free the vehicle when it is
stuck by "rocking" it. The selector lever lock en ­
gages if the lever stays in the N position longer
than 2 seco nds when the brake pedal is not
pressed.

A WARNING
- The vehicle can also ro ll when the eng ine is
stopped.
- Unintended vehicle movement can cause se­
rious injury.
- Never leave your veh icle with the engine
running while in gear. If you must leave
your veh icle w hen the engine is r unning, ac­
tivate t he pa rking brake a nd move the selec­
tor lever to P .
- Power is still transmitted to the wheels
when the engine is running at idle . To p re­
vent the vehicle from "creeping", yo u m ust
keep your foo t on t he b rake when the en­
g in e is ru nning and the selector lever is in D/
Sor R or "tiptronic" mode is se lected .
- Do not press the a cce le ra to r peda l when
changing the se lec to r l ever posi tion while
the vehicle is s ta tionary and the engine is
r u nning .
- Never sh ift into R or P whi le driving.
- Before d riving down a s teep sl ope, redu ce
your spee d and sh ift into a lower gea r w ith
"t i ptronic" .
- Do not ride the brakes or press the bra ke
pedal too of ten o r too long when dr iv ing
down a hi ll. Constant braking ca uses the
brakes to ove rheat and substantially re­
duces brak ing performance, increases b rak­
ing d istance or causes comp lete failure of
the brake system.
- To prevent the veh icle from rol ling back
when stopp ing on inclines, always hold it in
place with the brake peda l or park ing brake .
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An ind icator lam p. illumina tes
and a dr iver message appears¢
page 86
w hen t he clu tch is overloade d.
- If the e ngine must rema in running, never
have a ny driving posi tion engaged when
checking unde r th e hood. Make s ure these­
lec to r l ever has secu rely eng aged an d is
loc ked in P with the parking b rake set

Automatic transmission
Shifting with the shift paddle s*
You can operate the shift padd les in the D, Sor M
selector lever posit ions.
• To sh ift up one gear, tap the
0 shift paddle
¢fig. 93.
• To shift down one gea r, tap the O sh ift paddle.
• If you do not press a shift button within a short
time whi le in the D/S position, the transmission
will return to automatic mode. To keep shifting
using the shift buttons, move the selector lever
to the right out of the D/S position.
The transmission automatically shifts up or down
before critical engine speed is reached.
The transm ission only a llows manual shift ing
when the engine speed is within the permitted
range.
@ Tips
- When you shift into the next lower gear, the
transmission wi ll downshift only when there
is no possibility of over-revving the engine.
- When the kick-down comes on, the trans ­
mission will shift down to a lower gear, de­
pending on vehicle and engine speeds.
- Tiptronic is inoperative when the transmis­
sion is in the fai l-safe mode .
Kick-down
Kick-down enables maximum acceleration.
When you press the accelerator peda l down be­
yond the resistance point (called kick-down), the
automatic transmission downshifts into a lower
gear, depending on vehicle speed and engine RPM. It shifts up into the next higher gear once
the maximum specified engine RPM is reached.
A WARNING
Please note that the wheels could spin on
slick or slippery roads when kick-down is ac­
tive.
Transmission malfunction
• Transmission overheating! Please stop the
vehicle!
86
The transmission is too hot and can become dam­
aged. Stop and let the transmission coo l with the
engine running (at idle) in the P se lector lever po­
sition. Then the indicator light and the message
turn off, drive to an authorized Audi dealer or au­
thorized Audi Service Facility immediately to have
the malfunct ion corrected.
If the indicator light
and the driver message do not turn off, do not
continue driving. See an authorized Audi dea ler
or authorized Audi Service Facility fo r assistance.
Selector lever emergency release
In order to tow a vehicle due to power failure,
the selector lever emergency release must be ac­
tivated .

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 -
150
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.

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road ho ld ing and vehicle
dynamics to help reduce the probability of skid­
d ing and loss of vehicle control. It works only
when the engine is runn ing . E SC detects certain
d ifficult dr iving sit uat ions, including when t he
ve hicl e is begin ning to spin (yaw) out of contro l
and helps you to ge t the veh icle back under con­
tro l by se lective ly braking the wheels, and/or re ­
ducing engine powe r and provid ing steering as­
sistance to help hold the vehicle on the dr iver's
intended course. The indicator light
GJ in the in­
strument cluster blinks when ESC is taking action
to help you co ntrol the vehicle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not a lways be able to help out under all con­
d itions you may come up aga inst. For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coeff icient of friction of the road surface. When
there is a section of dry road that is sudde nly cov­
e red with water, slush o r snow, ESC cannot pe r­
form the same way it wo uld on the dry s urface . If
the vehicle hydrop lanes (rides on a cushion of wa­
ter i nstead of the road su rface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been interrupted and the
ve hicle cannot be braked or steered. Dur ing fast
cornering, pa rticula rly on w inding roads, ESC
cannot always deal as effect ively w it h difficult
d riving si tuations tha n at lowe r speeds. When
tow ing a t raile r, ESC is not able to help you re­
ga in con trol as it would if you we re not towing a
tra iler .
A lways adjust yo ur speed and driving sty le to
road, traffic and weathe r cond itions. ESC cannot
override the vehicle's physical lim its, increase the
Intellig ent Technology
available t ract ion, or keep a vehicle on the road if
road departure is a resu lt of driver inattention .
Instead, ESC improves the possib ility o f keeping
the vehicle under contro l and on the road d uring
extreme maneuvers by us ing the driver's steer ing
i nputs to help keep the veh icle go ing in the in ­
tended direction.
If you are traveling at a speed
that causes you to run off the road before ESC c an p rovide any assistance, you may not exper i­
en ce the benefi ts of ESC.
ESC is switched o n all the time . In certa in s itua­
t ions when you need less tract ion, you can sw itch
off AS R by press ing the button
[fil c:> page 152,
fig. 141. B e sure to switc h ASR on again whe n
you no longer need less tract ion .
T he following systems are integrated in the ESC:
Anti-lock brak ing system (ABS )
ABS prevents the wheels from locking when brak­ ing . The vehicle can still be steered even dur ing
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
stab ilize the ve hicle.
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking powe r when the dr iver
presses the brake peda l quickly in emergency sit­
uat io ns. You must press a nd ho ld the bra ke pedal
u nt il the dange rous situation is over.
Anti-slip regulation (ASR)
ASR reduces engine power whe n the dr ive wheels
begin spin ning and adapts the force to the road
co ndit ions. This makes it eas ier to s tart, acce ler­
ate and d rive up incl ines.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other dr ive
wheel or wheels if the vehicle is equ ipped with all
whee l drive*) . This function is not available a t
highe r speeds .
In extreme cases, EDL automat ica lly switches off
to keep t he brake o n the braked wheel from over­
hea ting . T he veh icle is still working co rrectly. EDL.,.
151

Intelligent Technology
will switch on again automat ically when condi­
tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the veh icle by changing
the steering torque.
Selective wheel torque control
Selective wheel torque control is used when driv ­
i n g on curves . The front wheel on the inside of
the c urve or 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 "Automatic post-collision brak ing system"
can help to reduce the r isk of slid ing and of other
coll is ions after an accident . If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
The 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 braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri­
cal system are not functioning.
A WARNING
- The ESC and its integrated systems cannot
overcome the limits posed by natural physi-
Switching on and off
cal laws. This is especially important on slip­
pery or wet roads. If the systems beg in act­
ing to stabilize your vehicle, you should im­
mediately alter your speed to match the
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks. This could increase your risk of
a collision.
- Please note the risk of a collision increases
when dr iv in g 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 collisions -there is still a risk of acci­
dents!
- Press the accelerator peda l carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and this can affect driving stability and
increase the risk of a collision .
@ Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
£SC turns on automatically when you start the engine .

The ESC is designed to function in levels. Depend­
i ng on the level that is selected, the stabilization
function of the ESC is limited or switched off. The amount of stabilization control will differ de­
pending on the level.
The following examples are unusual situations
where it may make sense to switch offroad mode
on to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck
- Dr iving in deep snow or on loose ground

Intelligent Technology
When the hill descent assist is on, the current
driving speed, when your vehicle entered the in­
cline is maintained. It is only possible to switch
on the assist when driving slower than 37 mph (60 km/h). The assist works between approxi­
mately 2 and 19 mph (4 and 30 km/h). The driver
can increase or decrease the vehicle speed within
these limits by depressing the accelerator or brake pedal.
There must be however sufficient ground adhe ­
sion . The hill descent assist
cannot do its job if
the incline is icy or if the incline ground is loose
¢ ,&.
Active assistance at a specific speed up to about 19 mph (30 km/h) is shown in the instrument
cluster through a blinking indicator light •. The
indicator light shines continuously when in the
ready mode.
The system does not work at speeds between 19
and 37 mph (30 and 60 km/h) . The system is
then in the ready-mode. This is shown through
the LED turned on in the button . The system au­
tomatically switched off when you drive faster
than 37 mph (60 km/h). The LED will also go out
in this scenario.
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 incline angle is at least around 10% .
A 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 physics. Your driving style
must always be adapted to the current road
and traffic conditions.
- The hill descent assist may not be able to
hold your vehicle at a constant speed under
all conditions while driving on an incline (for
154
example 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
compensate for the slightly reduced braking
force by pressing firmly on the brake pedal. Avoid heavy braking during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub­
ject to wear, depending largely on operating con­
ditions and driving habits¢,& . On vehicles that
are either driven mostly in stop-and-go city traf­
fic or are driven hard, the brake pads should be checked by your authorized Audi dealer more of ­
ten than specified in the
Warranty & Mainte­
nance booklet.
Failure to have your brake pads
inspected can result in reduced brake perform­
ance.
On steep slopes, you should use the braking ef­
fect of the engine. This way, you prevent unnec­
essary wear on the brake system. If you must use
your brakes, do not hold the brakes down contin­
uously. Pump the brakes at intervals.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water or 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
"dried" first with a few careful brake applica­
tions.
At higher speeds and with the windshield wipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This action
which is not felt by the driver happens at regular .,.

erf ul and has excellent drivin g charac teristics
both un der normal driving conditions and on
snow and ice . Always read and follow safety pre ­
cautions
c:> .&, .
Winter tires
By using all whee l dr ive, your ve hicle has goo d
f orward motion wi th standard tires in w inte r con ­
ditions . However, in winte r we recommend using
winter or all-season tires on all four wheels, be­
cause this will improve the brak ing effect

Snow chains
If there are snow chain laws, snow chains m ust
also be used o n veh icles with all wheel drive
c:> page 206, Snow chains.
Replacing tires
Fo r vehicles with all wheel drive, on ly wheels with
t h e same ro lli ng circ umfe rence sho uld be used .
Avoid whee ls with different t read depths
Q page 198 , New tires or wheels .
A WARNING
-Also, in vehicles with all wheel drive, adapt
your driving sty le to the current road and
traffic conditions. Do not let t he increased
safety prov ided tempt you in to taking r isks,
because this inc reases t he risk of an acc i­
dent.
- The braking ab ility o f your vehicle is limited
t o th e trac tion of th e wh eels. I n this way, it
is no t differe nt from a two wheel drive vehi ­
cle. Do no t be tempte d to accelerate to a
hi gh speed when the ro ad is slip pery this in­
creases the risk of an accident .
- N ote tha t on wet s tree ts, the front wheels
can " hydrop lane" i f driv ing at spee ds tha t
are too high. Unlike front wheel drive
veh icles, t he engine does not
rev higher sud­
de nly when t he vehicle begins hydroplan ing.
For this reason, pay attention to the road

conditions regar dless of your speed to
reduce the risk of an accident.
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 vehicle w ith a conventional energy sys ­
tem is not dr iven for a long time, the battery is
d rained by equ ipme nt (for example the immobi l­
iz er) . In certain circumstances, there could may
not be eno ugh energy to start the engi ne.
Your veh icle is equipped with an inte lligent ene r­
gy managemen t system for d istr ibut ing electrici­
ty . This significant ly imp roves the starting ab ility
and inc reases t he battery life.
The energy management system Is made up of
batt ery diagno sis, idling curr ent management
and dynami c en ergy managemen t.
B attery diagnosis
The battery diagnosis determines the battery
charge level. The senso rs determ ine the battery
voltage, t he battery cur rent, and the battery
temperature. The cu rrent charge level a nd the
pe rformance of the bat tery are dete rm ined based
on this .
Idling current management
The idling cu rrent management dec reases the
energy used wh ile parked . With the eng ine
sw itched off, it manages the energy dist ribution
t o the different elect rical componen ts. Date from
battery d iagnosis is taken into account for this.
D epending on the battery cha rge level, e lectr ica l
equ ipment is swi tched off one item after the oth­
e r, to p revent the ba tte ry from d raining and to
r etain the s tarting ab ility.
Dynamic energy management
Wh ile driving, dynamic energy management dis­
tr ib utes the approp riate amount of energy to the
e lectr ica l equipment. It controls the battery

- Energy management cannot overcome the
laws of physics . Note that the charge level
and length o f the battery life are limited.

What you should know
Maintaining the starting ability is the highest
priority.
A lo t of st ress is p laced on t he b attery when dr iv­
ing shor t distances, in traff ic, and at cold t imes
of the year . A lot of energy is used but litt le is
generated. It is also critical when the engine is
not running but e lectr ica l equipment is sw itched
on. In th is case, energy is used but none is gener­
ated.
In situations like this, energy management wi ll
active ly regulated the distr ibut ion of energy.
Long periods without us e
If you do not drive your vehicle for sever al days o r
weeks, electrical equ ipment is gradua lly scale d
back or sw itched off . This reduces energy use and
ensures the vehicle will be ab le to start after long
per iods of time . Some conven ience functions,
such as interior lig hting or power seat ad just­
ment, may not be ava ilable under certain circum­
stances. These conven ience functions wi ll be
available again once you sw itch t he ignition on
and sta rt the eng ine.
With the engine switched off
The battery w ill dra in if you use Infotainment
funct ions such as listening to the radio while the
engi ne is switched off .
The vehicle's ab ility to start may be impa ired by
the energy use, a message will appear in the In­
fota inment system display .
The message indicates that the system wi ll
switch off automatically soon. If you would like

to continue using the funct ions, you must start
the engine .
With the engine running
Although elect rical energy is genera ted whi le
d riving, the ba tte ry can d rain. Thi s can happe n
when little energy is gene rated, and much is used
and the charge leve l of the battery is not op tima l.
T o restore the balance of energy, components
that re q ui re la rge amou nts of energy a re tempo­
rar ily sca led bac k or swi tched off . Heating sys­
tems in particu lar require a grea t deal of energy.
If you notice, for examp le, that the seat heating*
or rear window defroster is not wo rking, then it
has been tempo rarily reduced or switched off.
These systems are available again as soon as the
energy supp ly has been restored.
In addition, you may notice that the idle speed
has slightly increased. That is norma l and no
cause for concern. Due to the increased idling
speed, the add itiona l req uir ed energy wi ll be
generated and the battery will be cha rged.
