overs .
Alwa ys rememb er: Airbag s wi ll deploy on ly once,
and on ly in cer tain kinds of collisions. Your safety
b e lts a re a lways there to offer protection in those
situations in which airbags are not supposed to
deploy, or when they have already deployed; for
examp le, when your vehicle str ikes or is struck by
another after the first collision .
This is just one of the reasons why an airbag is a
supp lementary restraint and is not a substitute
for a safety belt. The airbag system works most
effectively when used w ith the safety belts.
Therefore, always properly wear your safety belts
c::>page 144.
A WARNING
Sitting too close to the steer ing whee l o r in­
strument panel will decrease the effect ive­
ness of the airbags and will increase the risk
o f persona l injury in a coll is ion .
- Never sit closer than 10 inches (25 cm) to
the steering wheel or instrument panel.
- If you cannot sit more than 10 inches
(25 cm) from the steer ing whee l, investi­
gate whethe r adaptive equipment may be
available to help yo u reach the peda ls and
increase your seating distance from the
steering wheel.
- If you are unrestrained, lean ing forward, sit­
ting s ideways or out of position in any way,
your risk of in jury is much higher.
- You will also receive serio us injuries and
cou ld even be killed if you are up against the
airbag or too close to it when it inflates -
even with an Advanced Airbag.
- To reduce the r isk of injury when an airbag
inflates, always wear safety belts properly
¢ page 147, Safety belts .
- Always make certain that children age 12 or
younger always r ide in the rear seat. If chil­
dren are not properly restrained, they may
be severely injured or killed when an airbag
inflates .
- Never let children ride unrestrained or im­
properly restrained in the veh icle. Adjust the
front seats properly.
-
Airbag syste m
- Never ride with the back rest reclined .
- Always sit as far as possible from the steer -
ing wheel o r the instrument panel
c::> page 136.
- Always sit up right with your back against
the backrest of your seat.
- Never p lace your feet on the instrument
panel or on the seat. Always keep both feet
on the floor in front of the seat to help pre­
vent serious injur ies to the legs and hips if
the airbag inflates.
- Never recline the front passenger's seat to transport objects. Items can also move into
the area of the side airbag or the front air­
bag d uring braking or in a sudden maneu­
ver. Objects near the airbags can become
p rojectiles and ca use in jury when an airbag
inflates.
A WARNING

Airb ag syst em
Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu­
pants .
Fig. 165 Location of driver airbag : in steering whee l
Fig. 166 Location of front passenger's airbag: in the instru­
ment panel
Your vehicle is equ ipped with an "Advanced Air­
bag System" in compliance with Un ited States
Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicab le at the time your veh i­
cle was manufactured. The safety belts for the
seats have "pretensioners" that help to take s lack
out of the belt system . The pretensioners are also
activated by the electronic control unit for the
airbag system .
The front safety belts a lso have load limiters to
help reduce the forces applied to the body in a
crash.
The airbag for the driver is in the steer ing wheel
hub ¢
fig. 165 and the airbag for the front pas ­
senger is in the instrument panel¢
fig. 166. The
general location of the airbags is marked "AIR­
BAG".
156
There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detailed
i nformation about airbags, safety belts and child
safety in this and the other chapters that make
up the owner's literature. Please be sure to heed
the WARNINGS -they are extremely important
for your safety and the safety of your passengers, especially infants and small children .
,&_ WARNING -
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only supp lemental p rotection.
- Airbag work most effectively when used with properly worn safety belts .
- Therefore, always wear your safety be lts and
make sure that everybody in your vehicle is
prope rly restrained.
,&_ WARNING
A person on the front passenger seat, espe­
cially infants and small ch ild ren, will rece ive
serious i njur ies and can even be killed by be­
ing too close to the airbag when it inf lates .
- Although the Advanced Airbag System in your vehicle is designed to turn off the front passenger airbag if an infant or a sma ll child
is on the front passenger seat, nobody can
absolutely guarantee that dep loyment un­
der these special condit ions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle .
- The Advanced Airbag System can dep loy in
accordance with the "low risk" option under
the U .S. Federal Standard if a chi ld that is
heav ier than the typical one-year old child is
on the front passenger seat and the other
conditions for airbag deployment are met.
- Accident statistics have shown that ch ildren
are generally safer in the rear seat area than
in the front seating position .
- F or their own safety, all ch ildren, especially
12 years and younger, sho uld a lways ride in
the back properly restrained for their age
and size .

exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system
inspected immediately by your Audi dealer .
A WARNING
If, in exceptional circumstances, you must in­
stall a forward-facing child restraint on the
front passenger's seat:
- Always make sure the forward-facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Always follow the manufacturer's instruc­
tions provided with the child safety seat or
carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible before installing the child
restraint. The backrest must be adjusted to
an upright position.
- Always make sure that the
PASSENGER AIR
BAG OFF
light comes on and stays on all the
time whenever the ignition is switched on.
(D Tips
Always replace child restraints that were in­
stalled in a vehicle during a crash. Damage to
a child restraint that is not visible could cause
it to fail in another collision situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System " in compliance with United States
Federal Motor Vehicle Safety Standard (FMVSS)
208 as applicable at the time your vehicle was
manufactured.
The Advanced Airbag system in your vehicle has
been certified to meet the "low-risk" require­
ments for 3- and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
Child safety
the airbag that can occur, for example, by being
too close to the steering wheel and instrument
panel when the airbag inflates. In addition, the
system has been certified to comply with the "suppression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up to 12 months who are restrained on the front pas­
senger seat in child restraints that are listed in
the Standard.
Even though your vehicle is equipped with an Ad ­
vanced Airbag system, all children, especially
those 12 years and younger, should always ride in
the back seat properly restrained for their age
and size . The airbag on the passenger side makes
the front seat a potentially dangerous place for a child to ride. The front seat is not the safest place
for a child in a forward-facing child safety seat. It can be a very dangerous place for an infant or a
larger child in a rearward-facing seat.
Advanced Airbags and the weight-sensing mat in the front seat
The Advanced Airbag System in your vehicle de­
tects the presence of an infant or child in a child
restraint on the front passenger seat using the
weight-sensing mat in the seat cushion and the
sensor below the safety belt latch on the front
passenger seat that measures the tension on the
safety belt .
The weight-sensing mat measures total weight of
the child and the child safety seat and a child blanket on the front passenger seat. The weight
on the front passenger seat is related to the de­
sign of the child restraint and its "footprint", the
size and shape of the bottom of the child re­ straint as it sits on the seat . The weight of a child
restraint and its "footprint" vary for different
kinds of child 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 typical infants and typ­
ical 1 year-old child have been stored in the con­
trol unit of the Advanced Airbag System. When a

Smart Technolog y
A center differentia l distributes the driving power
variably to the front and rear axle. It works to­
gether with selective wheel torque contro l, which
activates when driving through curves
c:::;,page 191.
The all-wheel drive concept is designed for high
engine power . Your vehicle is exceptionally pow­
erful and has excellent driving characteristics bo th under normal driv ing condit ions and on
snow and ice . Always read and follow safety pre ­
cautions
c:::;, .&. .
Wint er tires
When driving in the winter, your vehicle with all­
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be advisa­
ble to mount winter tires (or all-season tires) for
improved dr iveability and braking: these tires
must be mounted on
a ll four wheels . See a lso
c:::;, page 250, Winter tires.
Tire chain s
Where tire chains are manda tory on certain
roads, this normally also applies to vehicles with
all-wheel drive c:::;, page 250, Snow chains.
Repl acing wheels /tire s
Vehicles with all-whee l drive must always have
tires of the same size. Also avoid tires with differ­
ent tread depths . For deta ils see page
c:::;, page 242, New tires or wheels .
A WARNING
Always adjust your driving to road and traffic
conditions. Do not let the extra safety afford­
ed by all-wheel drive tempt you into ta king
extra r is ks.
- Althoug h the all-whee l dr ive is very effec­
t ive, always remember that brak ing capac ity
is limited by tire traction . You should there­
fore not drive at excessive speeds on icy or slippery road surfaces .
- On wet road su rfaces, be careful not to drive
too fast because the front wheels could be­
gin to slide on top of the water (aquaplan­
ing). If this should occur, you will have no
warning from a sudden increase in engine
speed as with a front -whee l drive vehicle.
196
Always drive at speeds which are suited to
the road cond it ions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­ bility of electrical energy for starting the engine .
If a vehicle with a conventional energy system is
not driven for a long period of time, the battery
i s d ischarged by idling current consumers (e .g .
i mmob ili zer). I n certain c ircumstances it can re­
s ul t in the re be ing insuffi cient energy available to
start the eng ine.
Intelligent energy management in your vehicle
hand les the d ist ribution of electrical energy.
Start ing ability is ma rkedly improved and the life
of the ba ttery is extended .
Bas ica lly, energy management consists of
bat­
t e ry diagn osi s, idling curr ent man ag ement
and
d ynami c energy management .
Batte ry diag nosi s
Battery diagnosis continuously determines the
state of the battery. Se nsors determine battery
vo ltage, battery current and battery tempera­
tu re. This determines the cu rrent state of cha rge
and the power of the battery .
Idling current management
Idling current management reduces energy con ­
sumption whi le the vehicle is standing . W it h the
i gnition switched off, it cont ro ls the energy sup­
ply to the various electrical components. Data
from battery d iagnosis is cons idered.
Depend ing on the battery's state of charge , indi­
v idual consumers are gradua lly tu rned off to pre­
vent excessive discharge of the batte ry and thus
maint ain s tarting capability.
Dynamic ener gy management
While the vehicle is being driven, dynamic ene rgy
management distr ibutes the energy gene rated
accord ing to the needs of the individual compo-
nents. It regu lates consumption, so that more

you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle . Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
