The selector lever lock is effective only when the vehicle is
stationary and at speeds below 5 km/h. At higher speeds, the lock in
the N position is automatically switched off .
The selector lever is not locked when rapid shifts are made through
the N position (e.g. from R to Dl. This allows you to "rock" the vehicle
if it becomes stuck. If the lever is in the N position for more than
1 second with the brake pedal not depressed, the selector lock
engages automatically .
Release button
The release button in the selector lever handle prevents accidental
shifts into certain selector lever positions . When you press the
release button, the selector lever lock is cancelled . In the illustra ­
tion, the positions in which the release button has to be pressed are
highlighted in color~
page 718, fig. 121.
Ignition key removal lock
The ignition key can only be remove after the ignition is switched off
if the selector lever is in P. As long as the ignition key is removed, the
selector lever is locked in P.
[ i) Tips
If the selector lever does not engage, there is a malfunction . The
engine is disabled to prevent the vehicle from driving off uninten­
tiona lly. To allow the selector lever to engage again, proceed as
follows: Press and release the brake pedal. •

Launch Control Program
The Launch Control Program permits maximum accelera­
tion.
In order to use Launch Control, the ASR (Anti-Slip Regu la­
tion) must be disabled. When ASR is disabled, the ESP
warning/indicator light in the instrument cluster illumi ­
nates . So that Launch Control can be used, the engine must
be at operating temperature and the steering wheel must
not be turned.
- With the engine running, briefly press the ESP button.
The message "ASR off" appears in the instrument cluster
d isplay.
- Shift the gear lever to "S" or the tiptronic® position.
- Step on t he brake pedal with your left foot a nd keep the
brake pedal fully depressed fo r at least one second. _,,,

Transmission -_______________ ___.
- With your right foot, step on the accelerator to the wide­
open throttle position or Kickdown. The engine speed
settles at about 3,200 rpm.
Take your left foot off the brake.
The S tronic® in your vehicle is electronically controlled. A special
Launch Control Program provides the best acceleration from a
standing start.
& WARNING
• Always adapt your driving to the traffic flow.
• Only use Launch Control when road and traffic conditions allow
it and other drivers will not be endangered or annoyed by your
driving and the acceleration of the vehicle.
• Make sure that ESP remains enabled . With the ESP disabled,
the vehicle could brake away, particularly on a slick and slippery road -risk of skidding!
• Once acceleration is finished, switch ASR on again by briefly
pushing the ESP button. •

How the system works
The EDL operates automatically. It monitors the rotational speed of
the drive wheels on an axle with the help of the ABS sensors
=:,
page 194. If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power
to the other drive wheel or wheels (all-wheel drivel. This is done up
to a speed of about 60 mph (100 km/h). Noises from the brake
system signal that wheel spin is being controlled.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface
with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move. The wheel less able to transfer
power spins.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily . The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto ­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your ability to control your car. -Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning . This is
indicated by the ABS warning light=:,
page 16. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the vehicle starts up and acceler ­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=:,
page 194, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface. The system is active across the entire
speed range.
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action .
Activating
The ESP is automatically activated when the engine is started and it
performs a self -test . You can activate a deactivated ASR if required
by pressing the =:,
page 190, fig. 163 button . When it is activated,
the message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=:,
page 190, fig . 163. With the ASR deactivated, .,

•
the ESP check light comes on, see~ page 13. The message ASR off
appears in the display as well.
The ASR should normally be activated all the time . Only in certain
exceptional situations when some slip is desirable does it make
sense to deactivate the ASR. Examples:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck.
When the abnormal situation is over, you should activate the ASR
again.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending largely on operating conditions and driving habits~& .
On vehicles that are either driven mostly in stop-and-go city traffic
or are driven hard, the brake pads should be checked by your autho-
Intelligent technology
rized Audi dealer more often than specified in the Warranty & Main­
tenance booklet.
Failure to have your brake pads inspected can
result in reduced brake performance.
On steep slopes, you should use the braking effect of the engine.
This way, you prevent unnecessary wear on the brake system. If you
must use your brakes, do not hold the brakes down continuously.
Pump the brakes at intervals.
Moisture or road salt
If you are driving faster than 50 mph (80 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regular intervals so as to improve reaction time when braking on
wet surfaces. You, the driver, will not notice anything.
Under certain conditions, for example, when driving through water
or very heavy rain, or even after washing your vehicle, the braking
effect can be reduced due to moisture (or in freezing conditions ice)
on the brake pads. A few cautious brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the brakes can be reduced when the vehicle is
driven on a salt-covered road and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake discs and pads
with a few cautious applications of the brake~&.
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corrosion to form on the discs 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 corrosion 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~&. ..,

How the ABS system works
An aut omatic check is made whe n a speed of ab out 4 mph (6 km/h)
is reached. When this happens, a pumping noise can be heard.
I f an individua l wheel begins to rotate too slowly in relation to
ve hicle speed and ten ds to lock, the A BS automatical ly reduces
brake pressure to prevent that wheel from locking.
T his auto matic adjust ment p rocess wil l cause a
slight vibration o f
the brake peda l and some noises to alert you that veh ic le speed
must be ada pted to e xisting roa d and traff ic c onditions.
& WARNING
Although the ABS is very effective , always remember that braking
c apability is limited by tire tra ction . Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking e xtra risks .
The ABS cannot overcome the laws of physics.
[ i ) Tips
• I f ABS is not functioning properly, a warning light wil l come on.
See
=> page 16.
• I f a fau lt occurs in the ABS, the E DL is als o not fu ncti onin g. This
is indicated by the ABS warning light. •
Brake assistant
The brake a ssi st ant is de sig ned to a chieve th e opti mum
b ra kin g eff ec t.
The brake assistant helps to increase the effective braking power
and thus to ac hieve a s horte r stop ping dis tance. If the drive r
presses the brake pedal very quick ly, the brake assistant automati ­
ca lly b oosts the braki ng force to the maximu m level, up to th e point
where the anti -loc k brake function (A BS) intervenes to stop the
whee ls from loc king. You should then keep the brake pedal pressed

& WARNING
Please remember that the accident risk always increases if you
drive too fast , espe cially in corners or on a slippery road , or if you
follow the vehicle ahead of you too closely . An increased accident
risk cannot be compensated even by the brake assistant , so
always maintain a safe speed. •

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the func tion of the emission con tro l system
and could lead to damage.
<£> For the sake of th e envir onm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the sulfur content of the fuel
being used. Using a different brand of fue l may help, or filling the
tank with lead-free super grade gasoline. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low- lying parts such as spoi lers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports
chassis) and fully loaded vehicles. •

General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal driving style
• operating cond itions
• technica l limitations

Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating.
Avoid unnecessary accelerating and braking .
Vehicles use the most fuel when they are accelerating . If you antici­
pate what is going to happen next, you wi ll need to brake less and,
thus, acce lerate less. Let the vehicle coast whenever possib le - for
examp le when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep well below your car's max imum speed.
Acce lerating gently reduces fue l consumption , engine wear, and
does not disturb the environment.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approximate ly
three quarters of top speed, fuel consumption wil l be reduced by
