on together with the ABS and ESC indica­
tor lights, the ABS/ESC regulating function
may have failed. Functions that stabilize
t he vehicle are no longer avai lab le. This
cou ld cause the vehicle to swerve and in­
crease the risk of sliding . Drive caref ully to
the nearest a uthorized Audi dea ler and
have the malfunction corrected.

@ Tips
For safety reasons, the par king brake is re­
leased au tomatically only when the dr iv­
er 's safety belt is engage d in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline , do the following:
~ Keep the switch @¢ page 87, fig . 101
pulled and depress the accelerator. The
park ing brake stays app lied and prevents
the vehicle from rolling backward.
~ You can release the switch @once you are
sure that you are develop ing enough dr iv ing
force at the wheels by depress ing the accel­
erator .
Depending on the weight of the r ig (vehicle
and trailer) and the severity of the incl ine, you
may roll backwards as you start . You can pre­
ve nt rolling backwards by holding the parking
b rake sw itch @pulled out and accelerating -
jus t as you would whe n starting on a hill with
a conventional hand brake.
Emergency braking
In the event that the conventional brake sys ­
tem fails or locks.
~ I n an eme rgency, pull the sw itch @
¢page 87, fig. 101 and continue to p ull it
to s low your vehi cle down wi th the pa rk ing
brake .
~ As soon as you release the switch @ or ac-
ce lerate, the braking process stops.
I f you pull the switch @and ho ld it above a
speed of about 5 mph (8 km/h), the emergen ­
cy braking function is initiated . The vehicle is
braked at a ll four wheels by activating the hy­
draulic brake system. T he brake performance
is similar to making an emergency stop ¢
&. .
In order not to activate the emergency brak ­
ing by m istake, an a udible warning tone (buz­
zer) sounds when the switch @is pulled. As
soon as the switch @ is released, or the accel-
On th e ro ad 89
erator peda l is depressed, eme rgency braking
stops.
A WARNING
Emergency braking should only be used in
an emergency, when the norma l foot brake
has fa iled or the brake pedal is obstructed.
Using the parking brake to perform emer­
gency b rak ing will slow your vehicle down
as if you had made a full bra ke application .
T he laws of physics cannot be suspended
even with ESC and its asso ciated compo­
nents (ABS, ASR , EDS) . In corners and
when road or weathe r conditions are bad,
a full brake application can ca use the vehi­
cle to sk id or the rear end to break away -
risking an accident.
Speed warning system
Overv iew
The speed warning system helps you to keep
your driving speed below a set speed limit.
The speed warn ing system warns if the driver
exceeds a previous ly stored max imum speed.
A war ning tone w ill so und as soon as the vehi­
cle speed exceeds the set speed by about 3 mph (3 km/h). At the same time, a warn ing
symbol appears in the display. The symbo l's
appearance might be different in some mod ­
els.
T he speed wa rn ing system has one or two*
warning thresholds that func tion independ ­
en tly of each othe r and that have somewhat
different purposes:
Speed warning 1
You can use speed warn ing 1 to set the maxi­
mum speed while you are d riving. This se tting
will re ma in in effec t unti l yo u t urn
off the ig ni­
tion, assuming that yo u have no t changed or
reset the setting.

Side assis t fu nctions at speeds above ap prox i­
ma tely 19 mph (30 km/h).
@ V ehicles that are approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change
even if it is still
somewhat far away. The fas ter a vehicle ap­
p ro aches, the sooner the disp lay in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr it ical
for a lane change. All vehicles detec ted by
side assis t are in dicated by the time they en­
ter your "blind spot", at the latest.
© Vehicles left behind
If you s low ly pass a ve hicl e tha t sid e ass ist has
dete cted ( the difference in s peed between the
vehicle and you r vehicle is less than 9 mph
(15 km/h)), the display in the exter io r mirro r
turns on as soon as the vehicle enters your blind spot.
The disp lay wi ll not t urn on if you quickly pass
a vehicle that s ide assist has detected (t he d if ­
f erence in speed between the ve hicle and your
vehicle is greater than 9 mph (15 km/h)).
Functional limitations
T he radar senso rs are des igned to detect the
left and right adjacent lanes whe n the road
l anes a re the normal width. In certain situa­
t ions, the d isp lay in the exterior mirror may
turn on
even though there is no ve hicle locat­
ed in the area that is cr itical fo r a lane cha nge.
For example:
- if the lanes are narrow or if your are driving on the edge of your lane. If this is the case,
the system may have detected the vehicle in
another la ne that is
not adjacent to your
cur rent lane .
- if you a re driving through a c urve . Side assis t
may react to a vehicle that is one lane ove r
from the ad jacent lane .
- if side assist reacts to other objects (such as
high or d isp laced gua rd rails) .
- In poor weather conditions. The side assist fu nctions are limited .
Do not
cover the radar sensors c:;, fig. 127 with
stickers, depos its, bicycle wheels or other ob­
jects , because this will affect the funct ion. Do
not use s ide ass ist when tow ing a trail er. For
information on cleaning, refe r to
c:;, page 202 .
&_ WARNING
-Always pay a tten tion t o traffic and to the
ar ea around your ve hicl e. Side a ssist can ­
no t repla ce a driver's attention. The driv ­
er a lone is always respons ible fo r lane
cha nges a nd similar driving mane uvers.

122 Park ass is t
Sw it c hing off
.,. Drive faster than 9 mph (15 km/h), or
.,. take the vehicle out of reverse gear. The
acoustic parking system is immediately de ­
activated, and the rear view camera picture
is deactivated automatically after a per iod
of about 15 seconds, or
.,. switch off the ignition.
The delay in deactivating the camera provides an uninterrupted view behind the vehicle es­
pec ially when maneuvering in tight parking
spaces and prevents the picture from turning
off the every time you sh ift out of reverse .
If the warning message appears in the display but not the rear view camera picture, read and
confirm the warning message. The acoustic
d istance signal is always active .
If you press a function button on the MMI
control console, the rear view camera picture
d isappears. The rear view camera picture reap­
pears the next time you park.
Further information on the warn ing message
and the MMI control console can be found in
the MMI instruction booklet .
A WARNING
-Only use the rearview camera to assist
you if it shows a good, clea r picture. For
example, the image may be affected by
the sun sh in ing into the lens, dir t on the
lens or if there is a defect .
- Use the rearview camera only with the
rear lid completely closed. Make sure any
objects you may have mounted on the
rear lid do not block the rearview cam­
era .
(D Tips
-The rear v iew camera picture is ava ila b le
as soon as the MM I Display or the MM I is
switched on, or the start-up phase is
completed.
- The sensors must be kept clean and free
of snow and ice for the park assist to op­
erate. -

158 Airbag system
-Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only once. After an airbag has been deployed,
it must be replaced with new replace -ment parts designed and approved espe­
cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­ rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten ­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the restraint system including airbag modules
safety belts with pretensioners are scrap­
ped, all applicable laws and regulations
must be observed. Your authorized Audi
dealer is familiar with these requirements
and we recommend that you have your
dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi, lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electronic control
unit. Some suspension changes can, for

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 veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing situations, including
when the vehicle is beginning to spin (yaw) out of cont ro l and he lps you to get the vehicle
back under control by select ively b rak ing the
wheels, and/or red ucing engine powe r and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
DJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
h elp you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of wate r in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 185
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations 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 conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing t he vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC is switched on all the time. In certain sit­
uat ions when you need less traction, you can
switch off ASR by pressing the butto n
[ill
~ page 187, fig. 174 or~ page 187,
fig. 175. Be sure to sw itch ASR on aga in when
you no lo nger need less traction.
The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
when brak ing. T he vehicle can st ill be steered
even dur ing hard braking. App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal ind icates that
the system is helping you to brake the veh icle .
Brake assi st system
The brake ass ist system can decrease braking
distance. It increases brak ing power when the
drive r presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the s ituation is over. In
vehicles wi th adap tive c rui se control*, the
brake assis t system is more sensitive if the

Trailer towing tips
Important to know
Your vehicle hand les different ly when tow ing
a trailer because o f the addit ional weight and
d iffe ren t weight distribution . Safety, pe rform ­
ance and economy w ill greatly depend on how
caref ully you load your trailer and operate
your rig.
B efore you actua lly tow your trailer, pr actice
turning, stopp ing and bac king up in an area
away from traffic. Keep practicing until you have become comp lete ly fam iliar with the way
your veh icle-trailer comb ination behaves and
responds.
Backing up is d ifficu lt a nd requires practice .
Backing up with a tra iler genera lly requires
steer ing action opposite to that when backing
up your vehicle without a trailer.
M aintain a g reater distance betwee n your ve­
h icle and the one in front o f you . You will need
mo re room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius .
W hen pass ing, remember that yo u cannot ac ­
celerate as fast as yo u normally wo uld be­
cause of the added load. Ma ke s ure you have
e nough room to pass . After passing , allow
p lenty o f room fo r your tra iler before chang­
in g la nes aga in .
Avoid jerky starts, sharp turns or rap id lane
changes.
(D Tips
- Do not tow a tra iler during the break-in
period of you r vehicle.
- If you tow a trailer, your A udi may re­
quire more frequent maintenance due to
the extra load
o page 283.
Trailer towin g 201
Parking on a slope
Do not park on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.. App ly the foot brake.
.. Have someone p lace chocks under both the
veh icle and the tra iler wheels .
.,. With chocks in place, slowly release t he
bra kes unt il t he whee l choc ks absorb the
load .
.. Tu rn the whee ls towards the curb.
.,. App ly the par king b rake .
.. Place an a utomatic transm ission* in P, re ­
spectively a manual transmission in first or
reverse gear.
When restarting after parking:
.,. App ly th e foot br ake .
.. Start t he en gine.
.. Move the selector lever to D/S , respect ively
a man ual transmiss ion in first gea r.
.. Release the parking bra ke and s low ly pull
out and away from the wheel chocks .
.. Stop and have someone retr ieve the wheel
chocks.
@ Tips
If you move the selector leve r of the auto­
matic transmissio n* to P before applying
the pa rking brake and before blocking the
whee ls, you may hav e to use mor e forc e
l ater to m ove the le ver out of the P posi­
tion.
