System malfunction
If the t warning light in the instrument cluster flashes for approxi ­
mately one minute and then remains continuously illuminated and
additionally the
r fin'-=> fig. 30 symbo l appears in the display, the
tire pressure monitoring system is not available. This can have
various causes .
• If the message appears at the end of the learning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a whee l sensor were
installed.
• A wheel sensor or other component may have failed .
• During initia lization the system has detected more than 4 wheels
on the vehicle, for example whi le driving next to another car with a
tire pressure monitoring system.
Controls and equip ­
ment
Driver inform ation system
• A wheel change was made but the button => page 44, fig. 29 was
not pressed .
• Audi replacement parts were not used.
• If snow chains are being used, system function can be compro­
mised due to the shielding properties of the chains.
• The tire pressure monitoring system may not be available
because of a radio malfunction.
• Transmitters with the same frequency, such as radio head ­
phones in the vehic le or radio equipment, can cause a temporary
disruption of the system through excessive e lectromagnetic fields.
• Eliminate the interference if possible/if you can and then
proceed as follows: Turn off the engine for 20 minutes . Then drive
another 10 min. If the warning light comes on again, you should
contact your authorized Audi dealer immediately to have the
problem corrected.
• Do not use commercially available tire sealants. Otherwise, the
e lectrica l components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
toring system will have to be replaced by a qualified workshop. •

Pote nt ial malf un cti ons
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.

(D Note
Low obstacles a lready signa lled by a warn ing can disappear from
the system's detection range as they are approached and wi ll not
continue to be signalled. Objects such as barrier chains, trailer draw
bars, thin pa inted vertical poles , or fences may not be detected by
the system -risk of damage.

Cruise control
Switching the system on
The cruise control system makes it possible t o drive at a
constant speed sta rting at 20 mph (30 km/h) .

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 189. 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 184, fig. 142 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 184,
fig. 142. Both deactivation stages can only be activated from normal
mode.
Dea cti vat ing ASR
Tap the switch . Deactivation is indicated by s low 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 a ll -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

Ii ] Tip s
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 184, fig. 142 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 184, fig. 142. With the ASR deactivated,
the ESP check light comes on, see=>
page 18. 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.

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. 143
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. 143. At speeds between 10 mph (20 km/h) and 75 mph (120
km/h), retract the rear spoiler by tapping on the switch=> fig. 143 .

-Road driving?
Your Audi d oes not have en ough gr ound clea rance to be use d as a n
off -road vehicle. It is therefore best to avoid roug h tracks and
u neven terrain as much as possible. A lso refer to=>
page 194.
& 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 e xcessive speeds on icy or slippery
road surfaces.
• On wet road su rfaces , be careful not to dr ive 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 d rive at speeds which are suited to the road condi­
tions. -risk of cra sh. •

personal injur ies . Have worn or damaged tires repl aced immed i­
ately.
• Winter tires have ma ximu m speed rating th at may be lower
than your vehicle 's maximum speed.
• Never drive faster than the speed for which the winter or other
tire s installed on your vehicle are rated.
& WARNING
Alway s adjust your driving to the road and traffi c cond it ions .
Never let the good acceleration of the winter tires and all -wheel
drive tempt you into tak ing e xtra ri sks . Always remember :
• When braking , an all -wheel drive vehicle h andles 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.
c£> For the sake of the environment
Use summer tires when weather conditions permit. They are
quieter, d o not wear as qu ic kly and reduce fue l con sump tion. •
Snow chains
Snow c ha ins may be fitte d only to t he fr ont w heels , and only to
certain t ire sizes. Ask your authorized Audi dea ler on which tire
s izes snow chains ca n be used .
I f you are going to use snow chains, then you must instal l them on
the front whee ls at least.
The snow chains must have low-pro file l inks and must not be thicker
than 0. 53 inch ( 13 .5 mm), including the lock. Remove wheel center covers and
trim discs before putting snow
chains o n yo ur vehicle ~
(D. For safe ty reaso ns cover caps mus t
then be fitted over the whee l bolts. These are available from autho ­
r iz ed A ud i deale rs.
& WARNING
Using the wrong snow chain s for your vehicle or installing them
inco rrectly can increase the risk of loss of control leading to
serious personal injury.
• Snow chains are ava ila ble in d ifferent si zes . Always make sure
to follow the instructions provided by the snow chain manufac ­
turer .
• When driving with snow chain s never drive faster than the
speed permitted for your spe cific snow cha ins .
• Always observe local regulations .
0 Note
• Remove snow chai ns before d riving o n roads not cov ered w ith
snow to avoid damaging t ires and wearing the snow chains down
unnecessar ily .
• Snow chains, which come into direct contact with the wheel rim,
can scratch or damage it. Therefore, make sure t hat the s now c hains
are suitably covered.
