Engine does not switch off
Before and during each stop phase, the system
checks if certain conditions have been met. For
example, the engine will not switch
off in the fol­
lowing situations :
- The engine has not reached the minimum re­
quired temperature for Start-Stop mode.
- The interior temperature selected by the A/C
system has not been reached.
- The outside temperature is extremely high/low.
- The windshield is being defrosted®.
- The parking system* is be switched on.
- The battery charge level is too low.
- The steering wheel is turned at a sharp angle or
is moving .
- After engaging the reverse gear .
- On sharp inclines.
@j also appears in the instrument cluster dis­
play.
Engine automatically restarts
The standard Start-Stop mode will be canceled
during a stop phase in the following situations .
The engine restarts without any action by the
driver.

- The vehicle rolls, for example while on a slope.
- The interior temperature varies from the tem-
perature selected in the A/C system.
- The windshield is being defrosted®.
- The brake pedal is pressed several times in a
row.
- The battery charge level becomes too low.
- High power consumption.
The engine can turn
off again when the condi­
tions for Start-Stop mode are met.
Ignition is switched off automatically
To prevent the battery from draining, the igni­
tion
will switch off automatically under the fol·
lowing conditions:
- The vehicle has already been driven.
- The Start-Stop-System has stopped the engine.
- The driver's door is opened.
- The driver's safety belt is removed.
- The brake pedal is not pressed down .
- The vehicle is stationary.
In this case, the activated low beam is replaced
by the parking light. The parking lights will
switch
off after approximately 30 minutes or
when you lock the vehicle.
If the Start-Stop-System has not turned off the
engine or if you have switched the Start-Stop­
System
off manually, the ignition will not be au­
tomatically switched
off and the engine will con­
tinue to run

A WARNING
Never allow the engine to run in confined
spaces, because this increases the risk of as­
phyxiation .
(D Tips
-If you shift into the D or N position after
shifting into reverse, the vehicle must be
driven faster than 6 mph (10 km/h) in order
for the engine to switch off again .

Driving settings
Introduction
Drive select makes it possible to experience d if­
ferent types of vehicle settings in one vehicle.
The driver can select
Comfort, Auto and Dynami c
modes in the Infotainment system to switch be­
tween a sporty and a comfortable driving mode.
In the
Individual mode, the settings can be ad­
justed to your personal preferences. This makes it possible to combine settings such as a sporty
engine tuning with light steering.
A WARNING
-
Improper use of the Audi dr ive select can
cause collisions, other accidents and serious
personal injury.
Description
The follow ing systems are affected by drive se­
lect:
Engine and transmission
Depending on the mode, the eng ine and the
transmission respond quicker or in a more bal­
anced manner to acce lerator pedal movements.
I n the sporty dynamic mode, the transmission
shifts at h igher RPMs.
Air suspension*
The adaptive air suspension/adaptive air suspen­
sion sport*
(Air suspension in the MMI) is an
e lectronically controlled air suspens ion and
damping system. They are adjusted depend ing
on the selected dr iv in g mode, the driver's steer­
ing, braking and acceleration input and the road
surface, vehicle speed and load. A sporty setting
is generally used in vehicles with adaptive air sus­
pension sport*.
The vehicle clearance varies depending on these ­
lected mode and the speed.
The highway setting is activated automatically
when yo u drive above 75 mph (120 km/h) for
mo re than 30 seconds in the
Auto or Dynamic
100
mode. The ground clea rance is increased auto­
matically if the speed drops below 44 mph (70
km/h) for more than 120 seconds.
Steering
The steering adapts in terms of steering effort
and steering ratios. Indirect stee ring that moves
easily, like the steering in comfort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct steering.
The following applies to vehicles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the driver at a ll times . This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle con­
trol. At reduced speeds, however, steering is
more direct in order to keep the steering effort as
min imal as possible when the dr iver is maneuver­
i ng the vehicle. At low and average speeds, dy­
namic steering additionally provides more re­
sponsive steering performance.
Sport differential*
As a component of the all wheel dr ive system
(quattro)
c::;> poge 191, the Sport differentia l*
distributes the d riving powe r to the rear axle de­
pending on the situation . T he distr ibutio n of
power varies depending on the selected mode,
from ba lanced (comfort) to agile (dynamic). The
goal is a high level of agility and ability to accel­
erate on curves. The vehicle is very responsive to
steering.
Curve light*
The curve light adapts to driving on curves. The
pivoting action and the lighting are also adapted
to the mode.
Adaptive cruise control*
The behav ior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner . .,..

Parking system s
CD Note
Keep enough distance from the curb to avoid
damage to the rims .
@ Tips
The left or right orientation lines and surfaces
wi ll be displayed, depending on the turn sig­
nal being used .
Peripheral cameras
Introduction
Applies to vehicles: with peripheral cameras
With this equipment, die parking system plus* is
supp lemented with var io us peripheral cameras
qpage 114. Depending on vehicle equipment,
you are provided with the following views: Around the vehicle, front corner and rear corner,
in front of the vehicle and behind the vehicle.
General information

F ig . 1 30 Location of periphe ral cameras
Depending on the vehicle eq uipment, the periph ­
eral cameras are fou nd in the radiator grille, in
the luggage compa rtment lid and on both exteri ­
or mirrors *
q fig. 130. Make sure that the lenses
are not covered by deposits or any other obstruc­
tions as it may impair the system. For informa­
tion on cleaning, refer to¢
page 203.
In the Surrounding mode, black corners are
shown in the vehicle silhouette. Objects in these
areas are outside of the camera's field of v iew
and are not detected.

The accuracy of the orientation lines and the b lue
surfaces is reduced if the adaptive air suspen­
s ion* is fau lty, if the veh icle is lifted or if the
D y­
nam ic mode is activated qpage 100.
A WARNING
-Always read and follow the applicab le warn­
ings¢ .&
in General information on
page 113.
- If the position or the installat ion angle of a
camera was changed, after a collis ion for ex­
ample, do not continue to use the system
for safety reasons. Have it chec ked by your
authorized Audi dealer or authori zed A udi
Serv ice Facility.
- Keep in mind that the image in the display is
distorted if the exter ior mir ror ho using has
been manually adjusted.
- Use the
Rear mode and the corner view
( rear )
mode only when the l uggage com­
partment lid is fu lly closed. Otherwise the
image in the disp lay will be disto rted.
- The vehicle surroundi ngs a re shown using
the camera images. The veh icle image is
shown by the system. Objects and obstacles
above the camera are not displayed.
- Camera lenses enlarge and distort the field
of vision. The objects appear both a ltered
and inaccurate on the screen.
CD Note
- Always read and fo llow the applicable warn­
ings
¢ (Din General information on
page 113 .
-The Infotainment d isp lay shows the direc ­
tion in which the rear of the vehicle is travel­
ing based on the steering wheel ang le . The
front of the vehicle front sw ings out more
than the rear of the vehicle. Maintain plenty of distance so that your o utside mirror or a
corner of your vehicle does not collide with
any obstacles.

Airbag system
-An Advanced Airbag with gas generator and
control valve for the driver inside the steering
wheel hub.
- An Advanced Airbag with gas generator and
control valve inside the instrument panel for
the front passenger.
- A capacitive passenger detection system under­
neath the front passenger seat cover. This sys­
tem measures the electrical capacitance of the
person in the seat. The information registered
is sent continuously to the electronic control
unit to regulate deployment of the front Ad­
vanced Airbag on the passenger side.
- An airbag monitoring system and indicator
light in the instrument cluster~
page 153.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation registered is sent continuously to the
electronic control unit to regulate deployment
of the front Advanced Airbags.
- The
PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
panel
~ pag e 154, fig. 159 and tells you when
the front Advanced Airbag on the passenger side has been turned
off.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety b elt is latched or not and
transmits this information to the electronic control unit.
A WARNING
Damage to the front passenger seat can pre­
vent the front airbag from working properly .
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced Airbag System from functioning properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
- Never remove the front passenger or driver
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never disassemble or remove parts from the
seat or disconnect wires from it.
150
- Never carry sharp objects in your pockets or
put them on the seat. The capacitive pas­
senger detection mat in the front passenger
seat will not function properly if it is punc­
tured .
- Never carry things on your lap or carry ob­
jects on the front passenger seat . Such ob­
jects can influence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- Never store items under the front passenger
seat . Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, preventing them and the airbag sys­
tem from working properly.
- Never place seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced Air­
bag System from recognizing child re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restraint system on
this seat.
- Never use cushions, pillows, blankets, or
similar items on the front passenger seat.
The additional layers prevent the capacitive
passenger detection system from accurately
measuring the capacitance of the child safe­
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from
working properly.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device , power inverter or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such
devices can influence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- If you must use a child restraint on the front
passenger seat and the child restraint

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.
Always adjust your speed and driving style to road , traffic and weather cond itions . ESC cannot
override the vehicle's physical lim its, increase the
ava ilab le traction, o r keep a ve hicle on the road if
road departure is a resu lt of driver in attention .
I nstead, ESC imp roves the possibi lity of keep ing
Intellig ent Technology
the vehicle under contro l and on the road d uring
extreme mane uvers by using the driver's steering
i nputs to help keep the vehicle go ing in the in­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can provide any assistance, you may not exper i­
ence the benefits of ESC.
ESC is switched on all the time. In certain s itua­
tions when you need less tract ion, you can sw itch
off ASR by press ing the button
lm c> page 188,
fig . 177 . Be sure to switc h ASR on again whe n
you no longer need less traction.
The following systems are integrated in the ESC:
Anti-lock braking sy stem (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 veh icle .
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the dr iver
presses the brake peda l quickly in emergency sit­
uat ions. You must press and ho ld the brake pedal
unt il the dange rous situation is over . In vehicles
with adaptive c ruise cont rol*, the b rake ass ist
system is more se nsitive if the distance detected
to the ve hicle ahead is too sma ll.
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 a nd 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

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.
In vehicles with dynam ic steering*, ESC also
helps to stabilize the steering in critical situa­
tions.
Selective wheel torque control
Selective wheel torque control is used when driv­
ing on curves . The front wheel on the inside of
the curve 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 braking system"
can help to reduce the risk 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 automat ically 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.
Switchin on/off
A WARNING
- The ESC and its integrated systems cannot
overcome the limits posed by natural physi­
cal laws. This is especially important on slip­
pery or wet roads. If the systems beg in act­
ing to stabilize your vehicle, yo u 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 co llision.
- Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv­
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 pedal 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.
{l) 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.
ESC turns on automatically when you start the engine.

The following examples are unusual situations
where it may make sense to switch sport mode
on in order to allow the wheels to spin:
- Rock ing the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow chains

Intelligent Technology
if the car is not driven regularly or only for short
trips with little use of the brakes.
If the brakes are not used frequently , or if corro­
sion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed¢& .
Faults in the brake system
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have failed ¢
&..
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid level
is monitored e lectronically .
Brake booster
The brake booster works with vacuum pressure
which is created only when the engine is running
c:;> &, .
Brake lining wear status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c;> page 253, Replacing wheels .
A WARNING
-New brake pads don't have the best stop­
ping power and must be "broken- in" dur ing
the initial 250 miles (400 km) . You can
compensate for this by pressing the brake
pedal more firmly. This also applies later
when new pads are installed.
- You should perform braking maneuvers for
the purpose of cleaning the brake system
only if road conditions permit. Other road
users must not be put at risk -you may
cause an accident!
-
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or
too often . This could cause the brakes to get
hot and diminish brak ing efficiency.
190
- Do not "ride the brakes" by resting your foot
on the pedal when you do not intend to brake. This may cause the brakes to over­
heat, premature wear and increased stop­
ping distance.
- Under certain climatic and operating condi­
tions such as passing through water, driving in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced. In winter, ice can accumulate on the
brake pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful brake applications .
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you in­
stall a different spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem.
- Fa ilure of one brake circuit will impair the
braking capability resulting in an increased
stopping distance. Avoid driving the vehicle
and have it towed to the nearest Audi dealer
or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considerably
harder to make up for the lack of booster
assistance.

Winter tires
By using all wheel dr ive, your veh icle has good
forward motion with standard tires in w inter con­
ditions. However, in w inter we recommend using
winter or all seaso n tires on all four wheels, be­
ca use this will improve the brak ing effect.
Snow chains
If there are snow chain laws, snow cha ins must
also be used on veh icles w ith all wheel dr ive
