If a warning buzzer sounds for a few seconds when the ign ition is
switched on, there is a system malfunction with the acoustic park
assist. If the malfunction persists until the ignition is switched off,
there will be no acoustic warning at the next attempt to activate the system. Have the problem corrected.
There is no confirmation tone when reverse gea r is engaged if there
is a system malfunction .
For the parking assist to operate, the sensors must be kept clean
and free of ice.

the vehicle begins to skid, ESP brakes the appropriate wheel auto­matical ly .
The vehicle is stabilized again by the forces acting on the wheel during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed .
This brake application is accompanied by noises.
ESP works in conjunction with ABS=:>
page 187. If there is ma lfunc­
tion in the ABS, ESP is also inoperative .
Activa ting
The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode . With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=>
page 182, fig. 130 returns the
system to normal operation.
D eac tiva ting
ESP should norma lly be activated at all times because this ensures
optimum vehicle stability . Only in certain exceptional cases it does
make sense to deactivate Anti -Slip Regulation (ASR) or the Elec ­
tronic Stability Program !ESP) by pressing the button =:>
page 182,
fig. 130. Both deactivation stages can only be activated from normal
mode.
Dea cti vat ing ASR
Tap the switch . Deactivation is indicated by slow flashing of the ESP
lamp in the instrument c luster. In certain situations (e.g. driving
with snow chains, in deep snow or on loose ground, or when rocking the car free), it may be necessary to deactivate ASR. Deacti ­
vation is effective only up to a speed of about 45 mph (70 km/h). At higher speeds, ASR is switched on again automatical ly in front ­
whee l drive vehicles, deactivation is possible only up to about 30
mph (50 km/h). With all -whee l drive vehicles, ASR is active above

te llig ent tec hn olo gy
about 45 mph (70 km/h) and deactivated automatical ly below this
speed.
D eac tiva tin g ES P/ASR
Press the button for more than 3 seconds . Deactivation is indicated
by the ESP lamp in the instrument c luster staying on permanently .
This deactivates the E lectronic Stabi lity Program (ESP) in addition to
ASR . No Electronic Stability System operation and no Anti-Slip
Regu lation is availab le across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stab le vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
traff ic situation permit .
& WARNING
• The limi ts of ph ysics ca nnot be suspe nd ed by E SP. E ven in vehi ­
cles w ith ESP, you should always adapt your dr iving to road and
tr affi c co ndition s. Thi s is part icul ar ly tr ue on a s lippe ry and wet
road . Do not be te mpt ed b y th e incre as ed safet y prov ided t o ta ke

In the event of a defect in the rear spoiler system or in Audi
magnetic ride, it can happen that ASR and ASR/ESP cannot be deac ­
tivated, or they are activated automatica lly in the deactivated
state. •
Vehicle care Do-it-yourself service Technical data

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 182, fig. 130 button. When it is activated,
the message
ESP/ASR on appears briefly in the display. Vehicles
with front -wheel drive a deactivated ASR automatically re -activates
itself at a speed of 40 mph (70 km/h).
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 182, fig. 130. With the ASR deactivated,
the ESP check light comes on, see=>
page 17. The message ASR off
appears in the display as well. On vehicles with front -wheel drive:
deactivation is possible only up to 30 mph (50 km/h) for safety
reasons. Vehicles with all -wheel drive : the ASR can be deactivated
at any speed.
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 J 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
Intelligent technology
cause the system to reduce engine power when this is not desired.

Rear spoiler
The rear spoiler improves vehicle handling and enhances
driver control.
Fig. 131 Switch for
rear spoiler
The rear spoiler deploys and retracts. Spoiler operation can be set
for automatic or manual operation .
Automatic mode (normal operation)
• Automatic deployment : At a speed of about 75 mph (120 km/h),
the rear spoiler deploys automatically.
• Automatic retraction: When speed drops below about 50 mph
(80 km/h), the rear spoiler retracts automatically.
Manual mode
• Manual deployment: Tapping briefly on the switch ::::> fig. 131
deploys the rear spoiler .
• Manual retraction: At speeds up to about 10 mph (20 km/h),
retract the rear spoiler by pressing and holding the switch
::::> fig. 131. At speeds between 10 mph (20 km/h) and 75 mph (120
km/h), retract the rear spoiler by tapping on the switch=> fig. 131 .
Vehicle care I I irechnical data

• Be aware of the different than usual steering response and
adjust your steering force accordingly.
• Have the problem checked and set right by an authorized Audi
dealer as soon as possible.
• If a steering malfunction occurs, this is signaled with the or.
~ indicator lights and a warning tone, see.
[ i] Tips
• If the power steering system should fail, or if the engine is not
running (for example, while being towed} , you will still be able to
steer the vehicle. However, more effort will be required to do so.
• If the power steering system is not functioning properly, contact
your authorized Audi dealer immediately.
Ap plies to vehicles : w ith A ll Wheel Drive
0 iving w i h your quattro®
With All Wheel Drive, all four wheels are driven.
General information
With All Wheel Drive, power is distributed to all four wheels. This
happens automatically depending on your driving style and the
road conditions at the time. See also=> page
184, "Electronic differ ­
ential lock (EDU".
Winter tires
When driving in the winter , your vehicle with All Wheel Drive has an
advantage, even with regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-season tires} for improved
driveability and braking : these tires must be mounted on all four
wheels. See also=> page 250, "Winter tires".

Intelligent technology
Snow
chains
Where tire chains are mandatory on certain roads, this normally
also applies to vehicles with All Wheel Drive=> page 251, "Snow
chains".
Replacing wheels/tires
Vehicles with All Wheel Drive must always have tires of the same
size. Also avoid tires with different tread depths . For details see
page => page 246, "New tires and replacing tires and wheels".
Off-Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road vehicle. It is therefore best to avoid rough tracks and
uneven terrain as much as possible. Also refer to=> page 192.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks.
• Although the All Wheel Drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at excessive speeds on icy or slippery
road surfaces.
• On wet road surfaces, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (aqua­ planing}.
If this should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive
vehicle . Always drive at speeds which are suited to the road condi­
tions. -risk of crash. •

personal injuries . Have worn or damaged tires replaced immed i­
ately.
• Winter tires have maximum speed rating that may be lower
than your vehicle' s maximum speed.
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated .
& WARNING
Always adjust your driving to the road and traffi c conditions .
Never let the good acceleration of the winter tires and all -wheel
drive tempt you into taking extra risks. Always remember :
• When braking, an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads,
even winter tires cannot help under black ice conditions .

t o rq ue .
The design of wheel bolts is matched to the facto ry instal led rims . If
diff eren t rim s are fitt ed, t he cor rect w heel bol ts with the r ig ht le ngth
and correctly shaped bolt heads must be used. This ensures that
w hee ls a re fitted securely and t hat t he brake sys te m funct io ns
correctly.
In cer tain ci rc u ms tances, yo u may no t use whee l b olt s fro m a

page 295.
& WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control, a collision and serious personal injury .
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque.
• Only use wheel bolts that belong to the rim be ing installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss .
If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving. If the tightening torque is too high, the wheel
bolts and threads can be damaged and the wheel can become
loose .
