.&_ WARNING
-
Do not press the accelerator pedal inadver­
tently if the vehicle is stationary but the en­
gine is runn ing and a gear is selected. Other­
w ise the vehicle will start to move immediate­
ly and could result in a crash.
(D Tips
- If the parking brake is app lied with the igni­
tion switched off, the indicator lights in the
switch and -(USA models)/ . (Cana-
da models) in the instrument cluster will go
out after a ce rtain per iod of t ime.
- Occasional noises when the parking brake is applied and released are normal and are not
a cause for conce rn.
- When the vehicle is parked, the park ing
brake goes thro ugh a self-test cycle at regu­
l a r i ntervals. Any associa ted noises a re nor­
mal.

- When the veh icle is locked, no one -pa rtic u­
larly not chi ldren should rema in in the vehi­
cle. Locked doors make it more d ifficult for
emergency workers to get into the vehicle -
putting lives at risk .
Starting from rest
The starting assist function ensures that the
parking broke is released automatically upon starting.
Stopping and applying park ing brake

" When you sta rt to drive as usua l, the par king
brake is automatically released and your vehicle
beg ins to move.
When stopping at a traffic signa l or stopping in
city traffic, the parking brake can be applied. The
vehicle does not have to be held with the foot­
brake . The parking brake eliminates the tendency
to creep w ith a dr ive range engaged. As soon as
you drive off as usual, the parking brake is re ­
leased a utomat ically and the vehicle starts to
move .
Starting on slopes
When starting on incl ines, the sta rting assist pre­
vents the vehicle from un intent iona lly rolling
back. The braking force of t he parking brake is
not released u nti l sufficient dr iv ing force has
been built up at t he wheels .

Fo r safety reasons, the park ing brake is re­
l eased automatically only when the driver's
safety be lt is e ngaged in the b uck le.

Audi drive select
Audi drive select
Driving settings
Introduction
Aud i drive select makes it possib le to experience
d ifferent types of veh icle sett ings in one veh icle.
The driver ca n select three
Comf ort, Aut o and
Dyn am ic modes in the MMI to switch between a
sporty and a comfortable driving mode.
You can a lso adjust the setting accord ing to your
p references in the
indi vidual mode. For example,
you can combine settings such as a sporty engine tuning with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other accidents and serious
personal injury.
Description
-
The follow ing systems are affected by drive se­
lect:
Engine and t ransm is sion
Depending on the mode, the engine and the
transmission respond quicker or in a more ba l­
anced manner to accelerator pedal movements.
In the sporty dynamic mode, the transmission
shifts at h igher RPMs.
Air suspe nsion
The adaptive air suspension/adaptive air suspen­
sion sport*
(Air suspension in the MMI) is an
electronically controlled air suspens ion and
damping system . They are adjusted depending
on the se lected dr iving mode, the driver's steer­
ing, b raking and acceleration input and the road
surface, vehicle speed and load. A spo rty setting
is gene rally used in veh icles with adaptive air sus­
pens ion sport*.
The vehicle clearance va ries 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
au to or dynamic
106
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 rat ios. Indirect stee ring that moves
easily, like the steering in com fort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct steering .
The following app lies to veh icles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the dr iver 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 d irect in order to keep t he steering effort as
min imal as possible whe n the dr iver is maneuve r­
i ng the vehicle. A t low and ave rage speeds, dy­
namic steeri ng addit ionally prov ides more re ­
spons ive steering performance.
Sport differential*
As a component of the all whee l dr ive sys tem
(quattro)
~ page 195, the Sport differe ntia l*
dist ributes t he d riving powe r to the rear axle de ­
pend ing on the s ituation. The distr ib ution of
power va ries 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.
Cur ve light *
The curve light adapts to driving on curves . The
pivoting action and the lighting are also adapted
to the mode.
Adapt ive cruise control*
The behavio r whe n accelerating ca n be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise contro l also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner . ..,_

Depending on the vehicle equipment, you are as­
sisted by various views such as peripheral view,
corner views at the front and rear of the veh icle,
and v iews directly in front of or behind the vehi­
cle.
General information
App lies to: veh icles with top view camera system
e
Fig. 138 Location of periphera l came ras
Depending on the vehicle equipment, the periph­
eral cameras are found in the radiator grille, in
the luggage compartment lid and on both exter i­
or mirrors ¢
fig. 138. 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 206.
In the top vi ew mode, black corners are shown in
the vehicle silhouette . Objects in these areas are
outside of the camera's fie ld of view and are not
detected.
The accuracy of the orientation lines and the blue
surfaces is reduced if the adaptive air suspen­
sion* is faulty, if the vehicle is lifted or if the
d y­
namic mode is act ivated ¢ page 106.
.&, WARNING
-Always read and fo llow the applicable wa rn­
ings

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of skid­
ding and loss of vehicle control. It works only
when the engine is running. ESC detects certain
difficult dr iving situations, including when the
veh icle is beginn ing to spin (yaw) out of contro l
and helps you to get the vehicle back under con­
trol by se lectively braking the wheels, and/or re­
ducing engine power and providing steering as­
sistance to help hold the vehicle on the driver's
intended course. The indicator light
GI in the in­
strument cluster blinks when ESC is taking action
to help you control the vehicle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
ditions you may come up against . For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of friction of the road surface. When
there is a section of dry road that is suddenly cov­
ered with water, slush o r snow , ESC cannot per­
form the same way it wou ld on the dry surface. If
the vehicle hydrop lanes (rides on a cushion of wa­
ter instead of the road surface), ESC wi ll not be
able to he lp you steer the vehicle because contact
with the pavement has been interrupted and the
vehicle cannot be braked or steered. During fast cornering, part icularly on w inding roads, ESC
cannot always deal as effective ly w ith difficult
driving situat ions than at lower speeds . When
towing a trailer, ESC is not able to help you re­
ga in control as it would if you were not towing a
trai ler.
Always adjust your speed and driving sty le to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limits, increase the
190
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention.
Instead, ESC improves the possib ility of keeping
the vehicle under control and on the road during extreme maneuvers by using the driver's steering
inputs to help keep the vehicle going 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 certa in s itua­
tions when you need less traction, you can sw itch
off ASR by press ing the button above
~ page 192, fig. 186 the selector lever. Be sure
to switch ASR on again when you no longer need
l ess traction.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up when
braking. The vehicle can still be steered even dur ­
i ng hard braking . Apply steady pressure to the
brake pedal. Do not pump the pedal. A pulsing in
the brake pedal indicates that the system is help ­
i ng you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the dr iver
presses the brake pedal quickly in emergency sit­
uations. You must press and hold the brake pedal
u nt il the situation is over. In vehicles with adap ­
tive cruise control*, the brake assist system is
more sensitive if the d ista nee detected to the ve­
hicle ahead is too sma ll.
Anti-slip regulation (ASR)
ASR reduces engine powe r when the dr ive wheels
begin to spin and adapts the force to the road
cond itions. This makes it easier to start, acceler­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other wheels.
This function is not available at higher speeds .

In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL w ill switch on aga in a utomati­
cally when conditions have returned to normal.
Ste ering recommendat ion
The ESC helps to stabilize the ve hicle by chang ing
the s teering torque .
I n vehicles with dynamic steering*, ESC also
h e lps to s tabilize the stee ring in critical s itua­
tions.
Selective wh eel torqu e control
Select ive whee l torque control is used when driv­
in g on curves . T he front wheel on the inside of
the cu rve or both wheels o n the inside of the
curve are br aked selec tively as needed . This al ­
l ows more precise driv ing in curves . The applica­
b le system may not activate when driving in wet
or snowy conditions.
Automatic post-collision braking system
The "Automatic post-co llision bra king system"
can help to reduce the ris k of slid ing and of other
coll is ions after an accident. If the airbag contro l
module detects a col lision above a certain vehicle
speed, the vehicle is b raked by t he ESC.
The vehicle does not b rake automatica lly if :
- the driver p resses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greate r than the brak ing force
that wou ld be initiated by the system, or
- the ESC, the brake system or the vehicle electri ­
ca l system are not f unction ing .
Sma rt Technology
A WARNING
- The ESC and its integrated systems cannot
overcome the limits posed by natural physi­
cal laws . This is especia lly important on s lip­
pe ry o r we t roads .
If the systems beg in act­
i n g to stab iliz e your ve hicle, yo u should im­
mediately change yo ur speed to ma tch the
road and traffic con dit ions . Do not let the
increased safety provided by these systems
tempt you to take r isks. Do ing so will in­
crease the r isk of a loss of vehicle contro l,
coll is ion and serious pe rsonal in juries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle increases when driving too fast, especially through curves and on
slippery or wet roads, and when driving too
close to vehi cles up ahead. The ESC and its
i n teg ra ted systems ca nnot alw ays preven t
coll is io ns -the re is s till a risk of accide nts!
- Always accelerate w ith specia l care on even,
smooth s urfaces su ch as those that are wet
or covere d wi th ice and snow. The d rive
whee ls can spin eve n wit h these assistance
systems that cannot always help to reduce
the risk of loss of vehicle contro l.
(D Tips
-ABS a nd ASR only wo rk cor rec tly when all
four wheels a re equipped wi th identi cal
tires. Diffe rent tire s izes can lead to a red uc­
tion i n engine power .
- You may hear noises when the systems de ­
scribed are working .
191

Smart Techn olo gy
- 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 w inter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fully apply brakes fo r a tes t. Brakes w ill dry
and ice coatings wi ll be cleaned off after a
few careful brake applications .
- Driving for an extended pe riod of time on
salt-covered roads witho ut using your
brakes can also affect bra king efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few carefu l
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.
- Failure of one brake circuit will impair the
braking capability result ing in an increased
stopp ing distance. Avoid driving the vehicle
and have it towed to the nea rest Aud i 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 lac k of booster
assistance.
