Sw itching the ignition on /off
If you would like to switch the ignition o n wit h­
out starting the engine, fo llow these steps:
• Inse rt the key into the ignition lock.
• Press the key brief ly
wi thout p ress ing the b rake
pedal.
• To sw itch the ignition off , press the key again.
When starting the engine, major e lectr ica l loads
are sw itched off temporar ily.
You ca n only remove the key with the ignition
sw itched off .
If the engine should not start immedia tely , the
starti ng process is automatically stopped after a
short time . Repeat sta rting procedure .
A WARNING
-Never allow the engine to run in confined
spaces - dange r of asp hyxiation.
- Never remove the ignition key from the ign i­
t ion loo k while the vehicle is moving . Other­
wise, the steering lock cou ld sudden ly en­
gage and you would not be able to steer the
vehicle.
- Always ta ke the key with yo u wheneve r you
leave your vehi cle. Otherwise, the engine
could be started or electrical eq uipment
s uch as the power windows cou ld be operat­
ed . T his can lead to ser ious injury.
- Never leave ch ildren or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing peop le from escap ing
from the vehicle on their own in the event of an emergency . Depending on the time of
year, people inside the vehicle can be ex­ posed to very high o r very low tempe ra­
t ur es.
([) Note
Avoid high engine rpm, full throttle and heavy
eng ine loads until the eng ine has reached op­
erati ng temperature - otherwise you risk en­
gine dam age.

@) For the sake of the env ironment
Do not let the engine run while pa rked to
warm up. Begin dr iv ing immediately. Th is re­
d uces unnecessary em iss ions .
@ Tips
-If the key cannot be removed from the igni­
t ion lock, you have to pu ll the mechan ica l
key out of the master key in order to be able
to lock the vehicle
c::, page 33.
- After starting a co ld engine, there may be a
br ief per iod of increased noise because the
oil pressure must first build up in the hy­
draulic valve adjusters. This is norma l and
not a cause fo r concern .
- If you leave the veh icle with the ignition
switched on, the ig nition w ill switch off af­
ter a ce rtain period of t ime . Pleas e note tha t
ele ct rical eq uipme nt such as e xterior lights
w ill switch off a s well when that hap pens.

engine can be switched off while the vehicle is
moving. The engine will be switched off if you
press on the key for an extended period.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed . You must use
more force to turn or brake if necessary. Be­
cause you cannot steer and brake as you
usually would, this could lead to crashes
and serious injuries.
- For safety reasons, you should always park
your vehicle with the selector lever in P. Oth­
erwise, the vehicle could inadvertently roll
away.
- The radiator fan can continue to run for up
to 10 minutes even after you have turned
off the engine and removed the ignition key.
Driving
The radiator fan can also turn on again if the
engine coolant heats up because of intense
sunlight or heat build-up in the engine com­
partment.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the veh icle on their own in the event of
an emergency. Depending on the time of
year, people inside the vehicle can be ex­
posed to very high or very low tempera­
tures.
(D Note
If the engine has been under heavy load for
an extended period, heat builds up in the en­
gine compartment after the engine is switch­
ed off -there is a risk of damaging the engine.
Allow the engine to run at idle for about two minutes before switching it off.

Audi drive select Driving settings
Introduction
App lies to vehicles: with Audi drive select
Drive select provides the possibi lity to experience
d ifferent types of vehicle settings in one vehicle.
F or instance, using the three
Comfort, Auto and
Dynamic modes, the driver can switch from a
sporty to a comfortable driving mode with the
press of a button.
Addit ionally, in vehicles with
MM I*, the vehicle
setup for
Individual* mode can be customized by
you. This makes it possib le to combine settings
such as a sporty engine tuning with comfortab le
steering .
A WARNING
-
Improper use of the Audi drive select can
cause collisions, other acc idents and serious
personal injury.
Description
App lies to vehicles: with Audi drive select
The vehicle setup in each mode depends on the
veh icle's featu res . However, the engine, automat­
ic transmission and steering are always involved.
Engine and automatic transmission
Depending on the mode, the engine and the au­
tomatic transmission respond quicker or in a
more balanced manner to accelerator pedal
movements. In the sporty dynamic mode, the au­
tomatic transmission shifts at higher RPMs . Th e
engine sound is adjusted by opening or clos ing
the exhaust doors for the respective mode.
Steering
The steering adapts in te rms of steering effort
and steering ratios . Indirect steering that moves
eas ily, like the steering in comfort mode, is best
suited to long drives on a highway. In contrast,
~ dynamic mode provides sporty, direct steering.

ing effort for the driver at all times. This sets the
steering to be less sensitive at higher speeds in
order to provide improved vehicle control. At re ­
duced speeds, however, steering is more direct in
order to keep the steering effort as minimal as
possible when the driver is maneuvering the vehi ­
cle. At low and average speeds, dynamic steer ing
additionally provides more responsive steering
performan ce.
Sport differential*
As a component of the all wheel drive system
(quattro)
<=> page 174, the sport differential* dis ­
tributes the driving power to the rear axle de­
pend ing on the s ituation . The distribution of
power varies depending on the mode selected.
T he goal is a high level of agility and ability to ac­
ce lerate on curves. The vehicle is very responsive
to steering .
Audi 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.
Engine sound*
T he sound of the eng ine is adapted to the select­
ed mode and ranges from subtle to sporty.
(D Tips
-In some models, the maximum vehicle
speed can only be reached in the
Auto and
Dynamic modes.
- Selecting the
Dynamic mode results in spor­
ty shifting characteristics. The S gear posi­
tion engages automatically.
- In vehicles that have dynamic steering*, op­
erating noise is heard when starting or stop­
ping the engine. This does not indicate a
problem .

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
d ifficu lt driving situations, including when the ve­
hicle is beginn ing to spin (yaw) out of control and
helps you to get the vehicle back under control by
selectively braking the whee ls, and/or reducing
engine power and prov iding steer ing ass istance
to help hold the vehicle on the driver's intended
course. The indicator light
Bl in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
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 frict ion of the road surface . Whe n
there is a section of dry road that is suddenly cov­
ered with water, slush or snow, ESC cannot per­
form the same way it wou ld on the dry surface. If
the vehicle hydroplanes (rides on a cushion of wa­
ter instead of the road surface), ESC will not be
ab le 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, particularly on winding roads, ESC
cannot always deal as effectively with difficult
driving situations than at lower speeds. Whe n
tow ing a trailer, ESC is not able to help you regain
con trol as it wou ld if you were no t towing a trail­
er .
A lways adjust your speed and dr iving sty le to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limits, increase the
Smart Technology
available traction, or keep a vehicle on the road i f
road departure is a result of driver inattention.
Instead, ESC improves the possibility of keeping
the vehicle under control and on the road dur ing
extreme maneuvers by using the driver's steering
inputs 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 prov ide any assistance, you may not expe ri­
ence the benefits of ESC.
ESC is switched on all the time . In certain situa­
t ions when you need less traction, you can switch
off ASR by pressing the button
[ru ~ page 170,
fig. 152 or ~page 170, fig . 153. Be sure to
switch ASR on again when you no longer need
less traction.
T he 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 braki ng. Apply steady pressure to the
brake pedal. Do not pump the pedal. A pulsing in
the brake pedal indicates that the system is he lp­
ing you to brake the vehicle.
Brake assist system
The brake ass ist system can decrease braking dis­
tance . It increases braking power when the driver
presses the brake peda l quickly in emergency sit­
u at ions. You must press and hold the brake pedal
until t he situat ion is over. In vehicles with adap­
tive cruise control*, the brake assist system is
more sensitive if the distance detected to the ve­
hicle ahead is too sma ll.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive wheels
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
T he EDL brakes whee ls that are spinning and
transfers the drive power to the other wheels.
T his function is available up to about 60 mph
(100 km/h).
169

Smart Technology
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on again automati­
cally when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
I n vehicles with dynamic steering*, ESC also
he lps to stabilize the steering in critical situa­
tions .
Selective wheel torque control
Select ive wheel torque control is used when driv­
ing on c urves . The front wheel on the inside of
the curve or both whee ls on the inside of the
curve are braked selectively as needed. This al­
lows more precise driving in curves . Th e applica­
b le system may not activate when driving in wet
or snowy conditions .
A WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
c ially important on slippery or wet roads. If
the systems beg in acting to stabilize your
vehicle, you should immediately change
your speed to match the road and traffic
Switching on/off
conditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle increases when dr iving
too fast, especially through curves and on
slippery or wet roads, and when driv ing too
close to vehicles up ahead. The ESC and its
integ rated systems cannot always prevent
collisio ns -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
-ABS and ASR only work correctly when all
four wheels are equ ipped w ith identical
t ires. Different tire s izes can lead to a reduc­
t ion in engine power.
- You may hear noises when the systems de­ scribed are working.
ESC turns on automatically when you start the engine .
Fig. 152 Version A : lower center console,~ OFF button
The ESC is designed to function in levels. Depend­
ing on the level that is selected, the stabilization
function of the ESC is limited or switched off. The
170
Fig. 153 Version B: upper center console,~ OFF butto n
amount of sta bilization control will differ de­
pending on the level.

Smart Technolog y
-If y ou dama ge the front spo iler, or if you in ­
sta ll a di fferent spoile r, be sure the air flow
to the front brakes is not obstructed . Other ­
wise the brake system co uld overheat reduc­
ing the effectiveness o f the enti re brake sys­
tem .
- Failure of one brake c ircuit will impair the
braking capab ility r esult ing in a n increased
stopp ing distance. Avoid driving the veh icle
and have it towed to the nearest au thorized
Audi de aler or qualified workshop.
- Never let the vehicle ro ll to a stop with the
engine shut off .
-If the brake booster is not work ing, the
brake pedal must be pressed considerably
harder to make up for the lack of booste r as­
sistance .
