- Never turn off the eng ine unti l the vehi­
cle has come to a complete stop .
- The brake booster and power steer ing
only work when the engine is running . If
the engine is off, you have to use more
force when steering or braking. Because
you cannot stee r and brake as you usua l­
ly wou ld, this could lead to crashes and
ser ious injur ies.
- Avoid high engine rpm, fu ll throttle and
heavy engine loads unti l the engine has
reached operating temperat ure - ot her­
wise yo u risk eng ine dam age.
- The eng ine ca nnot be started by pushing
or tow ing the veh icle.
(D Tips
- After a cold engine is sta rted, there may
be a brief period of increased noise be ­

Introduction
Aud i d rive select mak es it possible to expe ri­
ence diffe ren t types of vehi cle se ttin gs i n o ne
ve hicl e. The dr ive r can se lect th ree
Comfort ,
Auto and Dynamic modes in the M MI to
switch between a sporty and a comforta ble
driving mo de.
You c an a lso a djust the setti ng according to
your p re ferences in the
Individual mode . F o r
examp le, you ca n combine settings such as a
sporty en gine t uning with comfortab le steer­
ing.
A WARNING
Improper use of the A udi drive select can
cause collisions, ot her acc idents and se ri­
ous pe rsonal injury.
Description
The vehicle setup in each mode depends on
the veh icl e's featu res. The engine, t ransm is­
sion, stee ring, reve rsible sa fe ty belt tension­
e rs a nd adap tive air su spension are alw ays in­
volved.
Engine and transmission
Depending on the mode, the e ng ine and the
tra nsmission respond quic ker or i n a more bal­
an ced manne r to acce le rator pedal move­
men ts. In the sporty dyn ami c mode, the
tra nsmission sh ifts at highe r RP Ms.
Air suspension*
The adaptive air suspens ion/adaptive air sus­
pension spor t*
(Air suspen sion in the MM I) is
a n e lec tronic ally con trolled air suspension and
da mpi ng sys tem. They are adjus ted depend­
ing on the se lected driving mode, the drive r's
steeri ng, braking an d acceleration input and
the road s urface, ve hicle speed and load. A
sporty setting is generally used in ve hicles
with adaptive air suspension sport*. T
he veh icle clearance varies depending on the
se lected mo de an d the speed .
T he highway setti ng is a ct ivated automatic ally
whe n you dr ive above 7 5 mph (120 km/ h) fo r
more than
3 0 seconds in the Auto or Dynamic
mode. The gro und clea rance is increased a uto ­
matically if the speed drops below
44 mph
(70 km/h) for more than 120 seconds.
Steering
T he s teer ing adap ts in terms of s teer ing effor t
and steering ratios . Indirect stee ring that
moves easily, like the steer ing in comfo rt
mode, is best suited to long drives on a high­
way. In contrast, dynamic mode provides sporty, direct steer ing .
Sport differential*
As a component of the all whee l drive system
(quattro)
¢ page 198, the Sport differential *
dist ributes the driving power to the rear ax le
depending on the sit uat ion. The distrib ution
of power var ies depend ing on the selected
mode, from balanced (comfort) to agile (dy­
nam ic) . Th e goal is a h igh level of ag ility and
ability to acce lerate on cu rves . Th e ve hicl e is
very res ponsive to stee ring.
Curve light*
The curve light adapts to driving on curves .
T he pivo ting act io n and the lighting are also
adapt ed to the mode .
Adaptive cruise control*
The behav ior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cru ise cont ro l
also responds to th e dr iv ing behavior o f th e
vehicle a head in a mo re co nse rvative o r sporty
man ne r.
Engine sound*
The sound of the eng ine is adapted to the se­
lected mode and ranges from sub tle to sporty . .,.

Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EDR), installed by some manu­
facturers fo r the express p urpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restr ict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during norma l vehicle op­
erat ion for diagnostic and repa ir purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a ve ry limited pe riod of
time and stored when a system fault or other
cond ition is sensed by a cont ro l unit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condit ion. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the eng ine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and he lps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing eng ine power and
providing steer ing ass istance to he lp hold the
vehicle on the dr iver's intended course. The in­
dicator light
G) in the inst rument cluster
blinks when ESC is ta king action to help you
control the veh icle.
ESC has limitations.
It is importa nt to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under a ll cond it ions you may come up aga inst.
For example, ESC may not always be able to
help you master situations where there is a
s u dden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is sudden ly covered w ith water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the ve hicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been in terrupted
and the vehicle cannot be braked or steered .
D uring fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather condit ions. ESC can­
not override the vehicle's physical limits, in­
crease the available tract ion, or keep a ve hicle
on the road if road departure is a result of
drive r inattent ion. Instead, ESC imp roves the
poss ibil ity of keeping the vehicle under con ­
trol and on the road during ex treme maneu­
vers by using the d river's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
ca uses you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

198 Intelligent technology
Clean off accumulated salt coating from
brake discs and pads with a few caref ul
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­ ed . Otherwise the brake system could
overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­ creased stopp ing distan ce. Avoid driv ing
the vehicle a nd have it towed to t he near­
est Aud i dea ler o r qualified workshop.
- Never let the vehicle rol l to a stop w ith
the engine shu t off.
- If the brake booster is not working, the
brake pedal must be pressed conside ra­
bly harder to make up for the lac k of
booster assistance.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering.
Power steering adapts electronically based on
the vehicle speed.

General information
With all Wheel Drive, power is distributed to all four wheels. This happens automatically
depend ing on your driving style and the road
condit ions at the time. See also ¢

Winter tires
When dr iving in the win ter, yo ur vehicle wi th
all-wheel drive has an advantage, eve n with

be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing : these tires must be mounted on

Replacing wheel s/tire s
Vehicles with a ll-wheel drive must always
have tires of the same size. A lso avoid tires

and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­

of au toma tic transmission, power steer ing ,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not) .
Aspect ratio
means the rat io o f the height to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overa ll handling on dry
pavement .
Bead

using winter tires during the winter
months . Low temperatures signif icant ly
dec rease the e lasticity of summer t ires,
which affects tract ion and brak ing ability.
If summer t ires are used i n very co ld tem ­
peratures, cracks ca n form o n the tread
