spot
G) Signal on outside mirror does not light up
A vehicle approaching slowly -in the left -hand lane for example -
was detected by the sensors. Because of the small difference in speed and the considerable distance from your vehicle, the signal
on
the outside mirror will not light up

page 164.
© Informational stage signal lights up
The distance between your vehicle and that of the slowly
approaching vehicle has narrowed. The informational stage signal
on the outside mi rror lights up.
As soon as the difference in speed and distance is registered as notable if you were to change lanes, a signal on the mirror lights up .
Side assis t will signal a t the latest when a detected vehicle enters
your "blind spot".

General information
Side assist has lim its and cannot detect vehic les under all road and
weather conditions. P lease remember system limitations and
never
rely on the system, especially when:
• driving through curves=>
page 763,
• lanes are of different widths=> page 163. •
Applie s to vehicles: with side ass ist
When dr iving through curves
Side assist cannot detect vehicles in curves with a turning radius of
less than 328 feet (100 m).
When driving through a curve , it is possible that side assist may
register a vehicle two lanes
over, and the signal on the outside
m irror will ligh t up .•

Side assist's detection area is designed to cover lanes of standard
width to the le ft and right o f your trave l lane, depending on whethe r
you drive in the center of your lane or c loser to the edge.
If you drive in narrow lanes, side assist's detection area may also
inc lude other lanes -especially if you tend to dr ive on the edge o f
your lane=> fig . 184. Under these conditions, vehicles can also be
de tected tha t are two lanes away, and s ide assist then could switch
between the informational and warning stage signa ls.
When d riving in
very wide lanes, vehicles in the adjacent lane may
not be detected because they are not inside the detection area. •

& WARNING
• Improper reliance on the side assist system can cause colli­
sions and serious personal injury:
& WARNING (continued)
- Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to
change lanes .
• Side assist cannot detect all vehicles under all conditions ­
danger of accident !
• Side assist cannot detect vehicles
in time to alert you when
they approach from behind at very high speed , or fall drop back
very quickly.
• The radar sensor's
vision can be reduced or entirely blocked by
rain , snow , and heavy spray. This can result in side assist not
adequately detecting vehicles or, in some cases, not detecting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
• Please note that side assist indicates there are approaching
vehicles , or vehicles in your blind spot , only after your vehicle has
reached a driving speed of at least 19 mph (30 km /h) .
• Side assist signal does not work around tight corners (turning
radius less than 328 feet , or 100
ml.
• Side assist is no replacement for the driver's full attention. The
driver alone is responsible for lane changes and similar driving
maneuvers . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .

Activation of the acoustic parking system is confirmed by
a brief acknowledgement sound . The indicator lig ht in
the switch lights up.
D ea ctivation
If you drive forwards faster tha n approx. 6 mph (10 km/h),
or
- if you switch the ign ition off, the entire acoustic parking
assist is automatically deactivated, or
- you can press the sw itch
P111! i n the center console
=> page 173, fig. 194 to deact ivate the Audi parking
system. The indicator light in the switch goes out.
You have to turn on the acoustic parking assist m anuall y if you wish
to park the vehicle forwards or if you w ish to approach an obstacle
forwards and want a distance warning .
The range at which the sensors start to measu re is

Distance warning is given by chimes which are generated by a
signal generator . The volume and the pitch of the chimes can be
adjusted in the MMI => page
183.
Mute
In the case of vehic les with automa tic transmission, an acoustic
distance warning is discontinued when the transmission selector l
ever is moved to the P position. However, the system remains
active . As soo n as the selector lever is moved from the
P posi tion
and the vehicle approaches an obstacle, the acoustic distance
warning resumes .
Dri ving fo rward/ba ckvv ard
Distance warning when driving forward/backward is based o n
detection of an obstacle in the range of the parking assist . As the
distance dec reases, the time interval between the audible tones
becomes shorter.
When the distance is less than approx . 1 ft (0.30 m), the tone
becomes continuous. At this point you shou ld s top backing up or
driving forward .
If the distance to an obstac le remains the same, the vo lume of the
distance warning is gradually reduced after about
4 seconds (does
not app ly to the zone for the cont inuous tone). If you sta rt to
approach the detected obstacle again, the distance warning will
sound at the normal volume again .
P a rk ing
When you selec t ano ther gear when parki ng (e .g . reverse/forward),
the warning tones are temporarily suppressed, but the visual display remains on the MMI display . If you start approaching a
detected obstacle again, the distance warning wi ll sound at the
normal vo lume again .
Visual disp lay
T he segments on the MMI display indicate a change in the distance
between the vehicle and an obstacle . The number of segments
displayed depends on the obstacles in front of or behind the
vehic le. The c loser the vehic le comes to the obstacle, the closer the
segments approach the vehic le => page
173 , fig. 195. When the
segment before last is disp layed, the veh icle has reached the colli­
sion zone. At this point you should stop backing up or driving
forward =>

restraints and for the different models of the same kind of child
restraint offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of
child restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typ ical infants and typical 1 year­
old child have been stored in the control unit of the Advanced
Airbag System. When a child restraint is being used on the front
passenger seat with a typical 1 year -old child, the Advanced Airbag
System compares the weight measured by the weight sensing mat
with the information stored in the electronic control unit.
The electronic control unit also registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using
the safety belt as compared to the tension on the belt when it is
used to attach a child restraint to the seat. The sensor below the
latch for the safety belt for the front seat passenger measures the
tension on the belt . The input from this sensor is then used with the
weight to "decide" , whether there is a child restraint with a typical 1
year-old child on the front passenger seat and whether or not the airbag must be turned off.•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, make sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been certified by its manufacturer for use with
an airbag. Always be sure that the chi ld restraint is properly
installed at one of the rear seating positions. If in exceptiona l
circumstances you must use it on the front passenger seat, carefully
read all of the information on child safety and Advanced Airbags
and heed a ll of the applicable WARNINGS. Make certain that the
child restraint is correctly recognized by the weight -sensing mat
inside the front passenger seat, that the front passenger airbag is
turned off and that the airbag status is always correctly signaled by
th e
PASSENGER AIR BAG OFF light .
Controls and equip­
ment Safety first Vehicle operation
Many
types and models of child restraints have been available over
the years, new mode ls are introduced regularly incorporating new
and improved designs and older mode ls are taken out of produc­
tion. Child restraints are not standardized . Child restraints of the
same type typically have different weights and sizes and different
'footprints,' the size and shape of the bottom of the chi ld restraint
that sits on the seat, when they are installed on a vehicle sea t. These
differences make it virtual ly impossible to certify comp liance with
the requirements for advanced airbags with each and every child
restraint that has ever been sold in the past or will be sold over the
course of the usefu l life of your vehic le.
For this reason, the United States National Highway Traffic Safety
Administration has pub lished a list of specific type, makes and
models of child restraints that must be used to certify compliance
of the Advanced Airbag System in your vehicle with the suppression
requirements of Federal Motor Vehicle Safety Standard 208. These
child restraints are:
A. Car beds, manufactured on or after September 1,
2004:
• Cosco Dream Ride 02-719
B. Rear facing child restraint systems, manufactured

Vehicle care Do-it-yourself service Technical data

The direction in which the driver wishes to travel is determined with
t he aid of the steering angle and vehicle speed and is continua lly
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehic le starts hydrop laning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the prob lem.
The vehicle is then stab ilized by the forces acting on the whee l
during braking. If the vehicle is oversteering (rear tends to skid out
of the turn), the brakes are mainly app lied on the wheel that is on
the outside of the curve. In the case of a vehicle that is understeering
(tendency to sl ide out of the curve), the brakes are applied at the
rear wheel that is on the inside of the curve . An acoustic signal indi­
cates when ESP brake application cuts in
~ & .
The system operates across the entire speed range in combination
with the ABS system
~ page 274 . If the Anti -Lock Brake System
(ABS) malfunctions, the ESP wi ll be out of action as well.
Ac tivat ion
When you turn on the eng ine, ESP will automatically be activated
and will perform a self -test.
The system can be activated or deactiva ted by pressing the button
~ page 270, fig. 256. The warning light comes on when the system
is switched off
~ page 18.
Normally , the ESP should always be on, however, it may be advanta­
geous to turn off the system in certain special cases when some
degree of wheel spin is desired such as :
• when driving with snow chains
• when driving in deep snow or on a loose surface (to allow the
wheels to dig in to reach firm ground)
• when trying to "rock" the vehicle free when it has beco me stuck.
T he system should be reactivated once you are no longer in such
situations .
Both the ABS and EDS systems are still functioning even if the ESP
is switched off .

How the system works
The EDL operates automatical ly. It monitors the rotational speed of
the drive wheels on an axle with the he lp of the ABS sensors
~ page 274. 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 w heel is braked, thereby transferring power
to the other drive wheel or wheels (all -whee l 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 control led .
