Intellig ent Technology
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all whee l drive, the dr iving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as we ll as
the cur rent road conditions . A lso see ¢
page 89 .
The all whee l dr ive concept is des igned for high
engine power. Yo ur vehicle is except iona lly pow­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­ cautions
q .&, .
Winter ti res
By using all whee l drive, your veh icle has good
forward motion w ith standard tires in winter con­
ditions . However, using winter or all season tires
on
all four wheels in the winter is recommended,
because th is w ill improve the
braking effect.
Snow chains
If there a re snow chain laws, snow cha ins m ust
also be used on ve hicles with all wheel drive
¢ page 181, Snow chains .
Replacing tires
For vehicle s wi th a ll wheel d rive, o nly wheels wi th
the same roll ing ci rcumfe rence sho uld be used.
Avoid using tires with di fferen t tread depths
¢ page 173, New tires or wheels.
A WARNING
- Also, in vehicles with all whee l drive, adapt
your driving style to the current road and traffic cond itions. Do not let the increased
safety prov ided tempt you into taking r isks,
because this increases the risk of an acc i­
dent.
- The braking ab ility of your vehicle is limited
to the trac tion of the wheels. I n this way, it
is not different from a two w heel d rive vehi ­
cle. Do no t be tempte d to accelerate to a
h igh speed when the ro ad is s lippery, be -
cause t his increases t he risk of an acci den t. ...,

Driving safety
Basics
Safe driving habits
Please remember -safety first!
The individual safety features of your vehicle can
work together as a system to help protect you
and your passengers in a wide range of accidents.
T hese features cannot work as a system if they
are not always correctly adjusted and correctly
used.
This chapter contains important information,
tips, instructions and warnings that you need to
read and observe for your own safety, the safety
of your passengers and others . We have summar­
ized here what you need to know about safety
belts, airbags, child restraints as well as child
safety. Your safety is for us
priority number 1. Al­
ways observe the information and warnings in
this section -for your own safety as well as that
of your passengers.
The information in this section applies to all
model versions of your vehicle. Some of the fea­
tures descr ibed in this sections may be standard
equipment on some models, or may be optional
equipment on others. If you are not sure, ask
your authorized Audi dealer.
A WARNING
- Always make sure that you follow the in­
structions and heed the WARNINGS in this
Manual. It is in your interest and in the in­
terest of your passengers .

tions.
Driving safety
Important things to do before driving
Safety is everybody's job! Vehicle and occupant
safety always depends on the informed and care­
ful driver .
For your safety and the safety of your passen­
gers,
before driving always:
.. Make sure that all lights and signals are operat­
ing correctly.
.. Make sure that the tire pressure is correct .
.. Make sure that all windows are clean and afford
good visibility to the outside .
.,. Secure all luggage and other items carefully
¢ page 102, ¢page 45.
.,. Make sure that nothing can interfere with the
pedals.
.. Adjust front seat, head restraint and mirrors
correctly for your height.
.. Instruct passengers to adjust the head re­
straints according to their height.
.. Make sure to use the right child restraint cor­
rectly to protect children
¢ page 134, Child
safety.
.,. Sit properly in your seat and make sure that
your passengers do the same¢
page 42, Front
seats.
.. Fasten your safety belt and wear it properly. Al­
so instruct your passengers to fasten their safe­
ty belts properly ¢
page 106 .
What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle , the driver as well as the driver's abili­
ty to concentrate on the road without being dis­
tracted.
The driver is responsible for the safety of the ve­
hicle 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 passengers
or by using a cellular telephone .
.. NEVER drive when your driving ability is im­
paired (by med ications, alcohol, drugs, etc .) .
.. Observe all traffic laws, rules of the road and
speed limits and plain common sense . .,.
97

Driving sa fety
• 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 pres­
sure or whe n you are stressed .
A WARNING
Impaired driv ing safety inc reases t he risk of
ser ious persona l inju ry and death whenever a
vehicle is being used.
Correct passenger
seating positions
Proper seating position for the driver
The proper driver seating position is important
for safe, relaxed driving .
Fig. 9 8 Correct seating pos it io n
For your own safety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the driver 's seat to the following
position :
• Adjus t the dr iver's seat so tha t you can easily
push the pedals all the way to the floor whi le
keeping your knee(s) s light ly bent ~
,A.
• 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 dis­
tance of at least 10 inches (25 cm) between the
stee ring wheel and your breast bone~
fig. 98 .
If no t possib le, see you r authorized Aud i dea le r
about adapt ive eq uipment.

• Ad just the steering wheel so that the steer ing
wheel and airbag cover points at your chest and
not at yo ur face .
• Grasp the top of the steering wheel with your
elbow(s) slightly bent.
• Adjust the head restraint so the uppe r edge is
as even as possib le w ith the top of your head .
If
that is not possib le, try to adjust the head re­
strai nt so that it is as close to this pos it io n as
possible.
• Fasten and wear sa fe ty belts correctly
r=>page 109.
• Always keep both feet in the footwell so that
you are in contro l of the veh icle at all t imes .

A WARNING
Drivers who are unbelted, out of position or
too close to the airbag can be seriously in­
jured by an airbag as it unfo lds. To help
re­
duce the risk of serious personal injury:
- Always ad just the driver 's seat and the
steering whee l so that there are at least
10 inches (25 cm) between yo ur breastbone
and the steering wheel.
- Always hold the steering wheel on the out­
side of the steering wheel r im with yo ur
hands at t he 9 o'clock and 3 o'clock posi­
tions to help reduce the risk of personal i n­
jury if the driver's airbag in flates.
- Never hold the stee ring wheel at the
1 2 o'cl ock position o r wi th you r hands at
o ther posi tion s in side the steer ing whee l
rim o r on the steeri ng wheel hub. Holding
the steering wheel the wrong way can cause serious inju ries to the hands, arms and head
if the drive r's airbag dep loys.
- Pointing the steering wheel towa rd your
face decreases the ability of the supplemen­
tal d river 's airbag to protect you in a coll i­
sion.
- Always sit in an upright pos ition and never
lean aga inst or place any part of your body
too close to the area where the airbags are
located.

' Advanced Airbag System components
The front passenger seat in your veh icle has a lot
of very impo rtant parts of the Advanced A irbag
System in it . These parts include the weight-
sensing mat, sensors , wir ing, brackets, and .,.

more. The function of the system in the front
passenger seat is checked by the electronic con­
trol unit when the ignition is on . The control unit
monitors the Advanced Airbag System and turns
the airbag indicator light on when a malfunct ion
i n the system components is detected . The func ­
tion of the airbag indicator light is descr ibed in
greater detail below . Because the front passen­
ge r seat contains important parts of the Ad­
vanced A irbag System, you m ust take care to p re­
vent it from being damage d. Damage to the seat
may prevent the Advanced Airbag for the front
passenger seat from doing its job in a crash.
The front Advanced Airbag System consists
of the following :
-Crash sensors in the front of the vehicle t hat
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An electronic control un it, with integrated
crash sensors for front and side impacts. The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit a lso "de ­
c ides " whether the safety be lt pretens ione rs
sho uld be activated .
- An Advanced Airbag with gas generator and
contro l valve for the d river ins ide the s teer ing
whee l hub.
- An Advanced Airbag with gas generator and
contro l valve inside the instrument pa ne l for
the fron t passenger.
- A weig ht-sensing mat unde r the upho lstery

components work together
The front Advanced Airbag System and the side
airbags supplement the protection offered by the
front three-po int safety belts and the adjustable
head restraints to help reduce the risk of injury in
a w ide range of acc ident and crash s ituations . Be
sure to read the important information about
safety and heed the WARNINGS in th is chapter.
Deployment of the Advanced Airbag System and
the act ivat ion of the safety belt pretensioners de­
pend on the deceleration measured by the crash
sensors and registered by the electronic control
un it. Crash severity depends on speed and de cel-

eration as well as the mass and stiffness of the
vehicle or object involved in the crash .
On the passenger side, regard less of safety be lt
u se, the airbag will be turned off if the weight on
the passenger seat is less than the amount pro­
grammed in the electronic control unit . The front
airbag on the passenger side will also be turned
off if one of the child safety seats that has been
certified under Federal Motor Vehicle Safety
Standard 208 has been recogn ized on the seat .

some important things to know.
A WARNING
To reduce the ris k of injury when an airbag in ­
f lates, always wea r safety belts properly.
- If you are un restrained, leaning forward, sit ­
ting sideways or out of position i n any way,
your risk of injury is much higher.
- You will a lso receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates -
even with an Advanced Airbag

The front airbags are designed to provide addi­
tional protection for the chest and face of the
driver and the front seat passenger when:
- sa fety belts are worn prope rly,
- the seats have been positioned so that the oc-
c u pant is properly sea ted as far as possible
from the airbag,
- and the head restra ints have been p roperly ad-
justed.
Because airbags inflate in the blink of an eye w ith
g reat fo rce, things you have on your lap or have
p laced on the seat cou ld become dangerous pro­
jectiles, and be p ushed into you if the ai rbag in ­
flates.
When an a irbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
ve hicl e. Thi s dust is made up mostly of a powder
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that whi le the sup­
p lemental airbag system is designed to reduce
the likel ihood of ser ious injuries, other i nju ries,
for example swelling, bruising and minor abra­
sions, can a lso happen when airbags inflate . Air­
bags do not protect the arms or the lower parts
of the body. Front airbags only supplement the
three po int safety belts in some frontal collisions
i n which the ve hicle decelerat io n is high enough
to deploy the airbags .
F ront airbag s will not deploy:
- if the ignit ion is switched off when a crash oc-
curs,
- in side collisions,
- in rear-end collisions,
- in rollove rs,
- when the c rash decelerat io n meas ured by the
airbag system is less than the minimum thresh­
o ld needed for airbag deployment as registered
by the electronic contro l unit.
The front passenger airbag will also not d eplo y:
- when the front passenger seat is not occ upied,
- when the we igh t on the fron t passenge r seat as
sensed by t he Advanced A irbag System indi-
Airb ag sys tem
cates that the front a irbag on the passenger
side has to be turned off by the e lectronic con­
trol unit (the
PASSENGER AIR BAG OFF light
comes on and stays on).
A WARNING
Sitting in the wrong position can increase the r isk of ser ious injury in crashes .
- To reduce the r isk of injury when the airbags
inflate, the driver and passengers must al­
ways sit in an upright posit ion, must not
lean aga inst or place any part of their body
too close to the area where the airbags are
lo cated.
- Occupants who are unbelted, out of posit ion
or too close to the airbag can be serio usly
in jur ed by an airbag as it unfolds with g reat
force in the blink of an eye
r=> page 115.
A WARNING
-A child in a rearward-facing child safety seat
insta lled on the front passenger seat will be
seriously injured and can be ki lled if the front
airbag inflates -even with an Advanced Airbag
System.
- The inflating airbag will h it the ch ild safety
seat or in fant carr ier with great force and
will smash the child safety seat and child aga inst the backrest, center armrest, door
or roof.
- Always install rear-fac ing child safety seats
on the rear seat.
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immedia tely insta ll
the rea r-facing child safety se at in a rear
seating posi tion and have the airbag system
inspected by your au thorized Audi dealer.
A WARNING
= -
Objects between you and the airbag will in -
crease the risk of injury in a crash by interfer­
i ng with the way the airbag unfolds or by be­
i ng p ushed into you as the airbag inflates.
