light sensor checked as soon as possible at a
dealership.
Adaptive light *
The benefit of adaptive l ight is that the curve
and the edge of the road are better i llum inat­
ed . The adaptive light is contro lled automati­
cally, depending on vehicle speed and steering
wheel angle.
When driving a round bends, the head lights
are contro lled according to steering wheel an­
g le . So that there is no black area ahead of the
ve hic le, the two main beams pivot at different
angles. The system works above a speed of
about 6 mph (10 km/h).
Com ing home /le avi ng home function *
The function is swit ched on when the switch is
in the AUTO* position and the function is
shown as active in the driver information sys­
tem.
The
coming hom e function illuminates the
area around the vehicle when the ign ition is
switched off and the driver's door is ope ned.
The length of time the lights remain on can be
set in the menu display
( Illumination > Exte­
rior lights > coming home ).
The leavi ng home function i lluminates the
area around the vehicle when unlocking it.
A WARNING
- Never use dayt ime running l ights to see
where you are going. They are not bright
enough and w ill not let you see far
enough ahead for safety, especially at
dusk or when it is dar k. Always switch on
the low beams at dusk or when i t is dar k.
- Automatic headlights a re only intended
to assist the dr iver. They do not re lieve
t he driver of his responsibi lity to check
t he headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
and rain cannot be detected by the light
sensors. So a lways switch on the head­
lights under these weather cond itions
and when driving in the dark
jO .
Clear vis ion 49
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists.
- Always turn on the headlights so that
youcanseeahe adandsothatothe ~
can see your car from the back .
- Please observe legal regulat ions w hen
using the ligh ting systems des cribed.
(D Tips
- T he light sensor for head light control is
located in the rear view mirror mount.
Do not apply any stickers to t he wind­
shield in th is area to preven t malfunc­
tions or fa ilures.
- Some exter io r l ighting funct ions can be
adjusted in t he driver i nformat ion sys­
t em
~page 24.
- I f you remove the igni tion from t he igni ­
t ion lock while the headligh ts are s till
on, a buzzer wi ll sound as long as the
driver's door is o pen to remind yo u to
t u rn off the lights.
- Always observe the specific local regula ­
tions for your area as to when to use your
lights.
- With automatic headlights, the high­
beam f unction is also available, but w ith
one restrict ion: If you have not sw itched
the high beams back to low beams dur­
ing automatic headlight operation (for
example, after d riving throug h a tunnel),
only the low beams come on the next
t ime au tomati c headlights a re swi tched
on. To use the high beams , you firs t have
t o pull the hig h beam lever back and
then push the lever fo rward again .
- In coo l or damp weather, the inside of
the headlights, turn signals an d tail
lights can fog over due to the tempera­
t u re difference between the inside and
outside. They w ill clear shortly after
switching them on. This does not affect
the se rv ice life of the lighting.

Seats and storage
General recommen­
dations
Why is your seat adjustment so important?
The safety belts and the airbag system can
only provide maximum protection if the front
seats are correctly adjusted.
There are various ways of adjusting the front
seats to provide safe and comfortable support
for the driver and the front passenger. Adjust
your seat properly so that :
- you can easily and quick ly reach all the
switches and controls in the instrument
panel
- your body is properly supported thus reduc­ ing physical stress and fatigue
- the safety belts and airbag system can offe r
maximum protection
¢ page 108.
In the following sections, you will see exactly
how you can best adjust your seats .
There are special regulations and instructions
for installing a child safety seat on the front passenger's seat. Always heed the informa­
tion regard ing child safety provided in
¢ page 129, Child Safety.
A WARNING
Incorrect seating position of the driver and
all other passengers can result in serious
personal injury.
- Always keep your feet on the f loor when
the vehicle is in motion -never p ut your
feet on top of the instrument panel, out
of the w indow or on top of the seat cush­
ion! This applies espec ially to the passen­
gers . If your seating position is incorrect
you increase the r isk of injury in the case
of sudden braking or an acc ident. If the
airbag inflates and the seating position
is incorrect this could result in personal
injury or even death.
- It is important for bo th the driver and
front passenger to keep a distance of a t
Seat s an d sto rage 59
least 10 inches (25 cm) between them­
selves and the steering wheel and/or in­
strument panel. If you're s itting any
closer than th is, the airbag system can­
not protect you properly. In addition to
this, the front seats and head restra ints
must be adjusted to yo ur body height so
that they can give you max imum prote c­
tion.
- Always try to keep as much distance as
possible be tween yourself and the s teer­
ing wheel o r instrument pane l.
- Do not adjust the driver's or front pas­
senger's seat whi le the vehicle is moving.
Your seat may move unexpected ly, caus ­
ing sudden loss of vehicle control and
personal injury . If you ad just yo ur seat
while the veh icle is moving, you are out
of posit ion.
Driver's seat
The correct seat position is important for safe
and relaxed driving.
We recommend that you adjust the driver's
seat in the fo llowing manner:
.,. Adj ust the seat in fore and aft direction so
t ha t you can easily push the peda ls to the
floor whi le keeping your knee sligh tly bent
c::> A in Why is your seat adjustment so im­
portant? on page 59 .
.,. Adjust the seatback so that when you sit
w ith your back against the seatback, you can
still grasp the top of the steering wheel.
.,. Pos it ion the head restrai nt accord ing to the
occupant 's height
c::> page 62 . For maxi­
mum protection, the top of the head re­
straint shou ld be at least at eye level, pref­
erably higher and idea lly level with the top
of the head
¢ page 94, fig. 100 .
A WARNING
Never place any objects in the dr iver's foot­
well. An object could get into the pedal
area and interfere with pedal funct ion. In
case of sudden braking or an acc ident, you
would not be able to brake or accelerate!

~ Push the lever Q fig. 80 -Arrow- ¢&_ .
~ Move the steer ing whee l to the desired posi ­
tion.
~ Push the lever against the steering column
until it locks.
There must be at least 10 inches (25 cm) be­
tween your chest and the center of the steer­ ing wheel. If you cannot sit more than 10 in­
ches (25 cm) from the steering wheel, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering wheel.
For detai led informat ion on how to adjust the
driver's seat, see
Q page 61.
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
- Adjust the steering wheel column only
when the veh icle is not moving to pre­
vent loss of veh icle control.
-
- Adjust the driver's seat or steering wheel
so that there is a min imum of 10 inches
(25 cm) between your chest and the
steering wheel¢
page 92, fig . 99. If
you can not maintain this min imum dis­
tance, the airbag system cannot protect
you properly.
- If physical limitations prevent you from
sitt ing 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive equ ipment is ava ilable .
- If the steer ing wheel is aligned with your
face, the supplemental dr iver's airbag
cannot provide as much protection in an
accident. Always make sure that the
steer ing whee l is aligned with your
chest.
- Always hold the steering wheel w ith your
hands at the 9 o'clock and 3 o' clock posi­
tions to reduce the risk of persona l injury
if the driver's airbag dep loys .
- Never ho ld the steering wheel at the 12
o'clock position or with your hands inside
the steering wheel rim or on the steering
wheel hub . Holding the steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

-Never remove the key from the ign ition
lock whi le the vehicle is mov ing . The
steering wheel will lock causing loss of
co ntrol.
- If you have to leave your veh icle - even
for just a m inute - a lways remove t he ig­
ni tion key and take it with you. This is es­
pecially important if you are going to
leave ch ildren behind in the vehicle. The

~ page 72, fig. Bl -do not depress the gas
peda l when starting the engine!
.,. Let go of the key as soon as the engine
starts .
A cold engine may at first be loud after it has
been started. This is due to the hydraulic
valves bu ild ing up the oil pressure. Th is nor­
mal and no need for concern .
If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the engine about 30 seconds later.
A WARNING
-Never start or let the eng ine run in a con-
fined o r enclosed area . Exhaust fumes
from the engine co ntain carbon monoxide,
a colorless and odo rless gas. Ca rbon mon ­
oxide can be f atal if inhaled.
- Never leave the engine id ling unattend­
ed. An una ttended veh icle w ith a runn ing

-Avo id high engine speeds, fast accelera ­
tion or heavy engine loads while the en­
gine is still cold. This could damage the
engine.
- The e ngine cannot be started by pushing
or towing the vehicle . .,..

If you have selected a lower gear than the cur­
rent one, the transmission will only shift down
when the engine cannot be overspeeded .
If kick-down is actuated, the transmission
shifts into a lower gear independent ly of
speed and engine rpm .

92 Driving Safel y
• Fasten your safety be lt and wear it properly .
Also instruct your passengers to fasten their
safety belts proper ly ¢
page 100.
What impairs driving safety?
Safe driving is directly related to the condi­
tion of the vehicle, the driver as well as the
driver's ability to concentrate on the rood
without being distracted.
The driver is responsible for the safety of the
vehicle and all of its occupants. If your ability
to drive is impaired, safety risks for everybody
in the vehicle increase and you also become a
hazard to everyone else on the road ¢
.&,.
Therefore:
• Do not let yourself be distracted by passen­
gers or by using a cellular telephone.
• NEVER drive when your dr iving ability is im­
paired (by medicat ions, alcohol, drugs, etc.) .
• Observe all traffic laws, rules of the road
and speed limits and plain common sense.
• ALWAYS adjust your speed to road, traffic
and weather conditions.
• Take frequent breaks on long trips . Do not
drive for more than two hours at a stretch .
• Do NOT drive when you are tired , under
pressure or when you are stressed.
A WARNING ,.
Impai red driving safety increases the risk
of serious personal injury and death when­
ever a vehicle is being used.
Proper occupant
seating positions
Proper seating position for the driver
The proper driver seating position is impor­
tant for safe, relaxed driving.
Fig. 99 The correct distance between driver and steer­
ing whee l
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the driver's seat to the
f o llow ing position:
• Adjust the driver's seat so that you can easi­
ly push the pedals all the way to the floo r
while keeping your knee(s) slightly bent
q &_.
• Adjust the angle of the seatback so that it is
in an upright position so that your back
comes in full contact with it when you drive.
• Adjust the steering wheel so that there is a
distance of at least 10 inches (25 cm) be­
tween the steering wheel and your breast bone¢
fig. 99 . If not possible, see your au­
thorized Audi dealersh ip about adaptive
equ ipment.
• Adjust the steering wheel so that the steer­
ing wheel and airbag cover points at your
chest and not at your face.
• Grasp the top of the steering whee l with
your elbow(s) slightly bent.
• Adjust the he ad restraint so the upper edge
is as even as possible with the top of your
head . If that is not possible, try to adjust
the head restraint so that it is as close to
this pos ition as possib le.
• Fasten and wear safety belts correctly
¢page 103.

~ Always keep both feet in the footwell so
that you are in control of the vehicle at all
times.
For detailed information on how to adjust the
driver's seat, see
c:> page 60.
A WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it deploys. To help
reduce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least
10 inches (25 cm) between your breast­
bone and the steering wheel.
- Always adjust the driver's seat and the
steering wheel so that there are at least
4 inches (10 cm) between the knees and
the lower part of the instrument panel.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock positions to help reduce the risk of per­
sonal injury if the driver's airbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering wheel
rim or on the steering wheel hub. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head if the driver's airbag in­
flates
- Pointing the steering wheel toward your
face decreases the ability of the supple­
mental driver's airbag to protect you in a
collision .
- Always sit in an upright position and nev­
er lean against or place any part of your
body too close to the area where the air­
bags are located.
- Before driving, always adjust the front
seats and head restraints properly and make sure that all passengers are prop­
erly restrained.
- Never adjust the seats while the vehicle
is moving. Your seat may move unexpect-
Driving Safely 93
ed ly and you could lose control of the ve­
hicle .
- Never drive with the backrest reclined or
tilted far back! The farther the backrests
are tilted back, the greater the risk of in­
jury due to incorrect positioning of the safety belt and improper seating posi­
tion .
- Children must always ride in child seats
c:> page 129 . Special precautions apply
when installing a child seat on the front passenger seat
c:> page 108.
Proper seating position for the front
passenger
The proper front passenger seating position
is important for safe, relaxed driving .
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the seat for the front
passenger to the following position :
~ Adjust the angle of the seatback so that it is
in an upright position and your back comes
in full contact with it whenever the vehicle is
moving.
~ Adjust the head restraint so that the upper
edge is as even w ith the top of your head as
possible but not lower than eye level and so
that it is as close to the back of your head as
possible
c:> page 94.
~ Keep both feet flat on the floor in front of
the front passenger seat .
~ Fasten and wear safety belts correctly
c:> page 103.
For detailed information on how to adjust the
front passenger's seat, see
c:> page 59 .
A WARNING
Front seat passengers who are unbelted,
out of position or too close to the airbag
can be seriously injured or killed by the air­
bag as it unfolds. To help reduce the risk of

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 102 Unbelted occupants in a ve hicle heading for a
wall
Fig. 103 The vehicle c ras hes into the wall.
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies with vehicle speed and body
weight . Engineers call this energy "kinetic en ­
ergy ."
The higher the speed of the vehicle and the greater the vehicle 's weight, the more energy
that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor . If
the speed doubles from 15 to 30 mph (25 to
50 km/h) , the energy increases 4 times!
Because the occupants in this vehicle are not
using safety belts
r::;, fig. 102, they will keep
moving at the same speed the vehicle was
moving just before the crash, until something
stops them -here, the wall
c:> fig . 103 .
The same principles apply to people sitting in
a vehicle that is involved in a frontal collision .
Even at city speeds of 20 to 30 mph (30 to 50
km/h), the forces acting on the body can
Safety belts 101
reach one ton (2,000 lbs, or 1,000 kg) or
more. At higher speeds, these forces are even
greater.
People who do not use safety belts are also
not attached to their vehicle. In a frontal colli­
sion they will also keep moving forward at the
speed their vehicle was travelling just before
the crash. Of course, the laws of physics don't
just apply to frontal collisions, they determine what happens in all kinds of accidents and col ­
lisions .
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!
Fig. 104 A driver not wear ing a safety belt is v io len tly
thrown forward
Unbelted occupants are not able to resist the
tremendous forces of impact by holding tight
or bracing themselves . Without the benefit of
safety restraint systems, the unrestrained oc­ cupant will slam violently into the steering
wheel, instrument panel, windshield, or what­
ever else is in the way r::;, fig . 104 . This impact
with the vehicle interior has all the energy
they had just before the crash.
Never rely on airbags alone for protection .
Even when they deploy , airbags provide only
additional protection . Airbags are not sup­
posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with airbags, all
vehicle occupants, including the driver, must
wear safety belts correctly in order to mini­
mize the risk of severe injury or death in a
crash.

108 Airbag sys tem
Airbag system
Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen­
gers, before driving off, a lways:
• Adjust the driver's seat and steering wheel
properly
c:> page 92,
• Adjust the front passenger's seat properly
c:> page 60,
• Wear safety be lts properly c:> page 102,
• Always properly use the proper child re-
straint to protect children
c:> page 129.
In a collision airbags must inflate within the
blink of an eye and with considerable force .
The supplemental airbags can cause injuries if
the dr iver or the front seat passenger are not
seated properly . Therefore in order to help the
a ir bag to do its job, it is important, both as a
d river and as a passenge r to sit properly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenger
compa rtment, the airbag can inflate fully and
comp letely and provide supp lemental protec­
tion in ce rtain frontal collisions
c:> page 92,
Proper occupant seating positions . For detai ls

I t's especially important that children a re
properly restrained
c:> page 129.
There is a lot that the d river and the passen­
ger can and must do to help the individua l
safety features ins talled in your A udi work to­
gether as a system.
Prope r seat ing pos ition is important so that
the front airbag on the drive r side ca n do i ts
job. If yo u have a physical impa irment or con- dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the pedals, or if you
have concerns with regard to the function or
operation of the Advanced Airbag System,
please contact your author ized Audi dealer or
qualified workshop, or call Audi Customer Re­
lations at 1-800-822-2834 for poss ible modi­
fi cat ions to your veh icle.
When the airbag system deploys, a gas gener ­
ator will f ill the a irbags, break open t he pad­
ded cove rs, and inflate between the steering
whee l and the dr ive r and between the instru­
ment pane l and the fron t passenger. The a ir­
bags will deflate immediately after dep loy­
ment so that the front occupants can see

All of th is takes p lace in the b link of an eye, so
fast that many peop le don't even realize that
the airbags have deployed. The airbags a lso
inflate with a great dea l of force and nothing
should be in their way when they deploy.
Front a irbags in combination wi th properly
worn safety belts slow down and lim it the oc ­
cupant's forward movement . T ogether they
help to prevent the drive r and passenger from
hitting parts of the inside the vehicle while re­
ducing the fo rces acting on t he occ upan t dur­
ing the crash . In this way they help to reduce
the risk of injury to the head and upper body in the crash. Airbags do not protect the arms
or the lower parts of the body.
Both front airbags wi ll not inflate in all fronta l
collisions . The triggering of the a irbag system
depends on the vehicle dece leration rate
caused by the co llision and registered by the
electron ic control unit. If th is rate is below
the reference value programmed in to the con­
trol unit , the airbags will not be triggered ,
even though the car may be badly damaged as
a resu lt of the co llision . Ve hicle damage, re­
pair costs o r even the lack of ve hicle damage
is not necessarily an indica tion of whether an
