The range at which the sensors start to meas­
ure is
a b ou t:
To the side 2 feet (0.60 m)
Center rea r 5 feet (1.60 m)
Activation
The parking assist
is activated when r ev erse
ge ar is engaged . A b rief tone confi rms that
the system is activated .
Backing up
Distance warning when back ing up starts
when an obstacle is detected in the range of
the park assist system . As the d istance de­
creases, the time i nterva l between the audible
tones becomes shorter.
When the d istance is less than 1 foot (0.30
m), the tone becomes cont inuous . At this
poi nt you should stop backing up.
Please note that low objects already signalled
by a warning can disappear from the system 's
detection range and w ill not continue to be
signalled.
Potenti al malfunction s
If a warning buz zer sounds for a few seconds
when the ignition is sw itched on, there is a
system malfunction w ith the acoustic park as­
sist . If the malfunction persists unti l the igni­
tion is switched off , there will be no acoustic
warn ing at the next attempt to activate the
system . Have the problem corrected.
There is no confirmation tone when reverse
gear is engaged if there is a system ma lfunc­
tion .
For the park ing ass ist to operate, the sensors
must be kept clean and free of ice.
_& WARNING
- Sensors have blind spots in which objects
cannot be detected . Pay special attention
to sma ll children and animals. They can- not a
lways be detected by the sensors -
danger of an accident!
- The parking assist cannot rep lace the
driver's attention. The driver alone is re­
sponsible for parking and similar driving maneuvers. Always watch where you are
driving.
(D Note
Low obstacles already signa lled by a warn­
i ng can d isappear from the system's detec­
tion range as they are approached and w ill
not continue to be signalled. Objects such
as barrier chains, trailer draw bars, th in
painted vertical poles, o r fences may not
be detected by the system - risk of dam­
age .
@ Tips
For the parking assist to operate, the sen­
sors must be kept clean and free of snow
and ice.

Transmission S tronic transmission
Introduction
Your vehicle is equipped with a S tronic trans­ miss ion, also called a double-clutch system/
transmission.
Power is transferred between the engine and
the transmission by means of two i ndepend­
ent clutches. They replace the to rque convert­
e r of conventional automat ic transm iss ions
and a llow the vehicle to acce lerate without a
noticeable break in the power flow .
W ith the aid
of tiptr oni c, the gea rs can op ­
tionally be sh ifted
manually¢ page 84.
Selector lever positions
All the selector lever positions are explained
in this section.
F ig . 89 Display: Selector lever position
The instrument cluster display shows these ­
l ector lever position.
P -Park loc k
In th is position the gea rs are mechan ically
l ocked .
The park lock must on ly be engaged with the
ve hicle
stationary¢ /1. .
To engage P and to remove the lever from th is
position, you must depress the release button
(button in the selector lever handle)
and si­
multaneously you must step on the brake
pedal.
Tran sm iss ion 8 1
R -re ver se
In this position, reverse is engaged.
Reverse gear must only be engaged w ith the
vehicle
stationary and the engine ru nning at
idle speed ¢
/1..
To engage R, you have to depress the release
button
and simultaneously step on the brake
pedal. I n the R pos ition, the bac k-up lights il­
luminate w ith the ignition on.
N -Neutral
The transm iss ion is in neutral in this pos ition.
D -Normal po sition fo r dri ving fo rward
In this position, the forward gears are auto­
matically shifted up and down, depending on
engine load and vehicle speed.
T o engage D from
N, the brake pedal must be
depressed at speeds below 3 mph (5 km/h) or
when the vehicle is stationary¢&. .
In certa in circ umstances (driving in the moun­
tains for examp le) it can be beneficia l to
switch temporari ly to the man ual shift pro­
gram ¢
page 84 in order to adjust the gear
ratios to driving conditions
manually .
S -Sport setting
The S set ting should be se lected for sporty
driving. The power reserves of the engine can
be fully exploited through later upshifts.
T o e ngage 5 from N, the b rake peda l must be
depressed at speeds below 3 mph (5 km/h) or
when the vehicle is stationary¢&. .
A WARNING
-Never p lace the selector lever i n the R or
P posit ion while the veh icle is moving -
risk of an accident!
- With the engine r unning, it is necessary
to hold the vehicle with the foot brake in
all se lector lever positions (except P and
N), because even at idle speed the trans­
fe r of power is never completely inter­
r u pted -the vehicle "creeps". If t he vehi­
cle is stat io nary and the transm ission is

82 Transmi ssion
engag ed, the engine shou ld neve r be
spe eded up unintentionally (e.g. manual­
ly from under the hood). Otherwise the
vehicle will immediately start to move -
sometimes even if the parking brake is
firmly applied -risk of an accident!
- Before you or other persons open the
hood and work on a running eng ine, the
selector lever must be move d to P and
t h e parking bra ke applied fi rm ly -ris k of
an a ccident! Fo ll ow the warning stickers .
a) Tips
If you have inadvertently s hifted into N
while the veh icle is moving, you should r e­
move your foo t from the accelerato r and
wait until the eng ine speed h as droppe d to
id le before shifting back to Dor S.

The selec tor leve r lock is effec tive on ly w hen
t h e veh icle is stationary and a t speeds below
3 m ph (5 km/h). At higher speeds, the lock in
t h e N position is automatica lly switched off .
T he selec tor leve r is not locked whe n rap id
shifts are made through the N posi tion (e.g.
from R to D). This a llows you to "rock" the ve­
hicle if it becomes stuck. If the lever is in the
N position for more than 1 second with the
brake pedal not depre ssed, the selector lock
engages au tomatically.

Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front a irbag on t he
passenger side to be turned off ("sup­
pressed") if a child up to about one year of
age restrained in one of the rear-facing or for­
ward -facing infant restra ints listed in Federal
Motor Vehicle Safety Standard 208 with which
the Advanced A irbag System in your vehicle
was certified has been installed on the front passenger seat . For a listing of the child re­
straints that were used to certify compliance
with the US Safety Standard¢
page 131.
The PASSENG ER AIR BAG OFF light in the in­
strument panel tells you when the front Ad­
vanced A irbag on the passenger side has been
turned off by the e lectronic control unit.
Each t ime you turn on the ignition, the
PAS ­
SENGER AIR BA G OFF
light w ill come on for a
few seconds and:
- will stay on if the front passenger seat is not
occupied,
- will stay on if there is a small child or child
restraint on the front passenger seat,
- wi ll go off if the front passenger seat is oc­
cupied by an adult as registered by the
weight-sensing mat
¢ page 118, Monitor ­
ing the Advanced Airbag System .
The PASSEN GER AIR BAG OFF light comes on
when the control un it detects a total weight
on the front passenger seat that requires the
front airbag to be turned off .
If the tota l weight on the front passenger
seat is more than that of a typical 1 year-old
child but less than the weight of a small
adult, t he front airbag on the passenger s ide
can dep loy (the
PAS SENGER AIR BAG OFF
light does not come o n). If the PASSENGER
AIR BAG OFF
l igh t does not come on , the
front airbag on the passenger side has not
been turned off by the electronic control unit
and can dep loy if the control unit senses an
impact that meets the conditions stored in its
memory .
For example , the airb ag ma y depl oy if :
- a small ch ild tha t is heav ier than a typical 1
year-old chi ld is on the front passenger seat
(regard less of whether the child is in one of
the child safety seats listed
¢ page 131), or
- a child who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
t h e instr ument pane l and stays on.
T he front airbag on the passenge r side may
not dep loy (the PASSENGER AIR BAG OFF
li ght does not illum inate and stay lit) even if a
small adult or teenager, or a passenger who is
not sitt ing upright w ith their back against a
non-recl ined backrest w it h their feet on the
vehicle floor in front of the seat is on the front
passenger seat¢
page 92, Proper seating po ­
sition for the driver .
If the front passenger airbag deploys, the
Federal Standard requ ires the airbag to meet
the "low risk" deployment cr iteria to reduce
the risk of injury th rough interact ion w ith the
airbag. "Low risk" deployment occurs in those
crashes that ta ke pla ce at lower dece le rat io ns
as de fined in t he electronic control uni t
¢ page 119, PASSENGER AIR BAG OFF light.
Always remember, a child safety seat or infant
ca rrier in stalled on the fron t seat may be
stru ck and knoc ked out of posit ion by the rap­
idly in flat ing passenger 's airbag in a fronta l
collision. The a irbag co uld great ly red uce the
effectiveness of the ch ild restraint and even
seriously in jure the chi ld during inflation .
A WARNING
-
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be serious ly injured and can be killed if
the front airbag inflates -even with an Ad­
van ced A irbag System.
- The inflating airbag will h it the ch ild
safety seat or infant carrie r with great
for ce and will smash the child safety seat
a nd child ag ai nst t he backrest, door or
roof.

-Never install a rearward facing child
safety seat on the front passenger seat
unless the
PAS SEN GER AIR BAG OFF
light comes on and stays on. If the PA S­
SEN GER AIR BA G OFF
light does not
com e on an d stay on th e inflating airbag
will hit the child safety seat or inf ant ca r­
rier with great force and will smash the
child safety seat and child against the
backrest, door or roof . Have the airbag
system inspected immediately by your
authorized Audi dealer .
- Forward-facing chi ld safety seats instal­
led on the front passenger's seat may in­
terfere with the deployment of the air­ bag and cause serious personal injury to
the ch ild.
A WARNING
If, in exceptional c ircumstances, you must
install a forward-facing child restra int on
the front passenger's seat:
- Always make sure the forward-fac ing
seat has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward-facing child re­
straint up aga inst or very near the instru­
ment pane l.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjus tment range, as far away from
the a irbag as poss ible be fore installing
the forward -facing child restraint. The
backrest m ust be adjusted to an upright
posit ion.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime whenever the ignition is switched
on.
A WARNING
To reduce the risk of serious injury, make sure that the
PASSENGER AIR BAG OFF
light will be d isplayed whenever a ch ild re­
st raint is installed on the front passenger
seat and the ig nit io n is switched on.

A WARNING
To reduce the r isk of injury when an airbag
inf lates , a lways wear safety belts prope rly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of in jury is much higher.

Advanced Airbag System components
The front passenge r seat in yo ur vehicle has a
lot of very important parts of the Advanced
Airbag System in it . These parts i nclude the
weight-sensing mat, sensors, wiring, brack­ ets, and more. The funct ion of the system in
the front passenger seat is checked by the electron ic control unit when the ignition is on .

More important things to know about
front a irbags
F ig. 112 Inflated front airba gs
Safety belts are important to help keep front
seat occupants in the proper seated pos it ion
so that airbags can u nfold prope rly and pro­
v ide supp lemental protection in a fronta l co l­
lision .
The front a irbags are designed to provide ad­
d itiona l protect io n for the chest and face of
the dr iver and the fron t seat passenger whe n:
- safety belts are wor n prope rly,
- the seats have been posit ioned so tha t the
occupant is proper ly seated as far as possi­
ble from the a irbag,
- and the head restraints have been properly
adjusted .
Because airbags inflate in the blink of an eye
with great force, things you have on your lap or have placed on the seat could become dan­
gerous projectiles, and be pushed into you if
the airbag inflates .
When an a irbag deploys, fine dust is released.
This is normal and is not caused by a fire in
the vehicle . This dust is made up most ly of a
powder used to lubr icate the airbags as they
deploy. It cou ld i rritate s kin .
It is important to remember that while the
supp lemental airbag system is designed to re ­
duce the likelihood of serious i njuries, other
inj uries, fo r example swell ing, bru isi ng a nd
minor abrasions, ca n also happen when air­
bags inflate. Airbags do not protect the a rms
or the lower pa rts of the body. Front airbags
only s upplement the t hree point safety be lts
in some frontal collisions in which the vehicle
A irba g sy stem 11 7
deceleration is high eno ugh to deploy the air­
bags .
Front airbags will not deploy :
-if t he ignition is sw itched off when a crash
occu rs,
- in side co llisions,
- in rear-end co llis ions,
- in rollovers,
- when the crash dece leration measured by
the airbag system is less than the minimum
threshold needed for a irbag deployment as
reg istered by the electronic con tro l unit .
The front pa ssenger airbag will also not
deploy:
- when the front passenge r seat is not occu­
pied,
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys ­
tem ind icates that the front a irbag on the
passenger side has to be tu rned off by th e
elec tronic con trol un it (the
PASSENGER AIR
BAG OFF
li ght comes on and st ays o n).
&_ WARNING ~
Si tti ng in the wrong pos ition can inc rease
the r isk of se rious in ju ry in crashes.
- To reduce t he ris k of injury when the air­
ba gs inflate, the drive r and passenge rs
must always s it in an upr ight position,
m ust not lean against or place any part
of their body too close to the area whe re
the airbags a re located.
- Occupants who are unbe lted, out of posi­
tion or too close to the airbag can be se­ rious ly injured by an airbag as it unfolds
with g reat force in the blink of an eye
~page 109 .

A WARNING
Objects between you and the a irbag will
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
or by being pushed into you as the a irbag
inflates.
- Never hold th ings in your hands or on
yo ur lap when the vehicle is in use.
- Never transport items on or in the area
of the front passenge r seat. Objects
c ou ld move into the area of the front air­
bags dur ing braking or other s udden ma­
neuver and become dange rous projec ­
tiles that can cause serious personal in­
jury if the airbags inflate.
- Never place o r attach accessories or oth­
er objects (such as cup ho lders, tele­
phone brackets, large, heavy or b ulky ob­
jects) on the doors, over or near the area
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those a reas and yourself. These
objects co uld cause injury in a crash, es­
pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can also
move in to the area o f the side airb ag or
the front airbag dur ing braking or in a
sudden maneuver. Objects near the air -
-
bags can become projectiles and cause
inju ry, partic ularly when the seat is re­
clined.
A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems for people
with a history of asthma or other breath­
i ng cond itions.
- To reduce the risk of breath ing problems,
those with asthma o r othe r respiratory
conditions shou ld get fresh air righ t
away by getting o ut of the ve hicle or
open ing win dows or doors.
- I f you are i n a collision in which airbags
deploy, wash your hands and fa ce with
mild soap and wate r before ea ting.
- Be ca reful not to get the dust into your
eyes, o r into any c uts or s cratches.
- If the res id ue should get into your eyes,
flush them w ith wate r.
