Airbag system 111111
-----------------------------=--=-------
It is important to remember that while the supplemental airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example swelling, bruising and minor abrasions, can
also happen when airbags inflate. Airbags do not protect the arms
or the lower parts of the body. Front airbags only supplement the
three point safety belts in some frontal collisions in which the
vehicle deceleration is high enough to deploy the airbags.
Front airbags
will not deploy:
• if the ignition is switched off when a crash occurs,
• in side collisions,
• in rear -end collisions,
• in rollovers ,
• when the crash deceleration measured by the airbag system is
less than the minimum threshold needed for airbag deployment as
registered by the electronic control unit.
The front passenger airbag
will also not deploy:
• when the front passenger seat is not occupied,
• when the weight on the front passenger seat as sensed by the
Advanced Airbag System indicates that the front airbag on the
passenger side has to be turned off by the electronic control unit
(the PASSENGER AIR BAG OFF light comes on and stays onl.
& WARNING
Sitting in the wrong position can increase the risk of serious injury
in crashes.
• To reduce the risk of injury when the airbags inflate, the driver
and passengers must always sit in an upright position, must not
lean against or place any part of their body too close to the area
where the airbags are located.
• Occupants who are unbelted, out of position or too close to the
airbag can be seriously injured by an airbag as it unfolds with
great force in the blink of an
eye :::::, page 189.
Controls and equip­ ment Safety first
Vehicle operation
& WARNING
A child in a rearward-facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates
-even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center arm rest, door or roof.
• Always install rear-facing child safety seats on the rear seat.
• If you must install a rearward facing child safety seat on the
front passenger seat because of 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 by your
Audi dealer .
& WARNING
Objects between you and the airbag will increase the risk of injury
in a crash by interfering with the way the airbag unfolds or by
being pushed into you as the airbag inflates .
• Never hold things in your hands or on your lap when the vehicle
is in use.
• Never transport items on or in the area of the front passenger
seat. Objects could move into the area of the front airbags during
braking or other sudden maneuver and become dangerous projec ­
tiles that can cause serious personal injury if the airbags inflate.
• Never place or attach accessories or other objects (such as cup
holders, telephone brackets, large, heavy or bulky objects) on the
doors, over or near the area marked "AIRBAG" on the steering
wheel, instrument panel, seat backrests or between those areas
and yourself. These objects could cause injury in a crash, espe­
cially when the airbags inflate.
• Never recline the front passenger's seat to transport objects.
Items can also move into the area of the side airbag or the front _,,

& WARNING (continued)
• If you must install a rearward-facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on ,
immediately install the rear -facing child safety seat in a rear
seating posit ion and have the airbag system inspected by your
Audi dealer .
• A tight tether or other strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure
on the weight-sensing mat in the seat and register more weight
than is actually on the seat. The heavier weight registered can make the system work as though an adult were on the seat and
deploy the Advanced Airbag when it must be suppressed causing
serious or even fatal injury to the child.
• If , in exceptional circumstances , you must install a forward ­
facing child restraint on the front passenger seat , always move the
seat into its rearmost position in the seat 's fore and aft adjust­
ment range , as far away from the airbag as possible. The backrest
must be adjusted to an upright position . Make sure that the
PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on .
& WARNING
• If the PASSENGER AIR BAG OFF light does not go out when an
adult is sitting on the front passenger seat after taking the steps
described above , make sure the adult is properly seated and
restrained at one of the rear seating positions .
• Have the airbag system inspected by your Audi dealer before
transporting anyone on the front passenger seat .

& WARNING
Improper care , servicing and repair pro cedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly :
• Never cover, obstruct, or change the steering wheel horn pad
or airbag cover or the instrument panel or modify them in any way.
• Never attach any objects such as cup holders or telephone
mountings to the surfaces covering the airbag units .
• For cleaning the horn pad or instrument panel , use only a soft ,
dry cloth or one moistened with plain water . Solvents or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly .
• Never repair , adjust , or change any parts of the airbag system.
• All work on the steering wheel, instrument panel, front seats or

a ll measured .
The direction in which the driver wishes to travel is determined with
the aid of the steering angle and veh icle speed and is continua lly
compared with the actual behavior of the vehicle. If the two do not
match, -for example, when the vehicle starts hydrop la ning on a
wet road -
, ESP will au tomatical ly brake the appropria te wheel to
correct the problem .
The vehicle is then stabi lized by the forces acting on the whee l
during braking . If the vehicle is
oversteering (r ea r tends to skid out
of the turn), t he brakes are main ly app lied on the whee l that is on
the outside of the curve . In the case of a vehicle that is
understeering
(tendency to s lide out of the curve) , the bra kes are applied at the
rear whee l that is on the inside of the curve. An acoustic signal indi ­
cates when ESP brake appl ication cuts in

The system operates across the entire speed range in combination
wi th the ABS system
~ page 240. If the Ant i- Lock Brake Sys te m
(ABS) malfunctions, the ESP wi ll be out of act ion as well.
Ac tivat ion
When you turn on the engine, ESP will automatica lly be activated
and will perfo rm a self -test.
You can activate a deactivated ESP or deact ivated ASR as requ ired
by pressing the
=> page 236, fig. 199 button.
D eac tiva tion
Norma lly, the ESP should always be on .
When necessary, you can deact ivate Anti -Slip Regulat ion (ASR) or
the Electronic Stabilization Program (ESP) by pressing the button
=> page 236, fig. 199 .
• Dea ctivating A SR: Tap briefly on the ESP button . In certain excep ­
t iona l situations (e .g. driving wit h tire chains or a t a forced pace
around a track), the Anti-S lip Regu lation (ASR) can be deactivated

& WARNING
The Electronic Stabilization Program i s neve rthele ss subject to the
laws of physi cs . It is part icularly important to pa y attent ion to thi s
fact on we t and slippery roads . It is therefore important that you
always adapt your driving to the condit ion of the road and traffic
c onditions. Do not allow the inc reased safety provided by the Elec ­
tronic Stabiliz ation Program sy stem to lull you into a ccepting
additional safety ri sk s.
• Plea se note that when ESP or ASR is dea ctivated , the drive
wheels can spin on icy and slippery roads and the vehicle can
break a way -da nger of skidding! •

& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics.
[ i] Tips
• If ABS is not functioning properly, a warning light will come on.
See~ page 21.
• If a fault occurs in the ABS , the EDL is also not functioning. This
is indicated by the ABS warning light. •
Brake assistant
The brake assistant is designed to achieve the optimum
braking effect.
The brake assistant helps to increase the effective braking power
and thus to achieve a shorter stopping distance . If the driver
presses the brake pedal very quickly, the brake assistant automati ­
cally boosts the braking force to the maximum level, up to the point
where the anti-lock brake function (ABS) intervenes to stop the
wheels from locking. You should then keep the brake pedal pressed
until the vehicle has braked to the required speed. The brake assis ­
tant switches itself off as soon as you release the brake pedal.
The brake assistant will not be operative if there is a malfunction in
the ABS.
Controls and equip­
ment Safety first
Vehicle operation
& WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow the vehicle ahead of you too closely. An increased accident
risk cannot be compensated even by the brake assistant, so
always maintain a safe speed. •
Servotronic® -advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort. Your Audi is equipped with the electronically controlled
Servotronic® advanced power steering system. It adjusts
the degree of steering assistance to the roadspeed.
The advanced Servotronic ® power steering system senses the road
speed and electronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
vehicle speed .
Power steering will not work if the engine is off. As a result, the
steering wheel will be hard to turn.
The power steering fluid level is checked during the scheduled
maintenance services.
0 Note
If there is an electronic malfunction, servotronic will still function
like a conventional power steering system, providing a constant
steering support force that is no longer proportionate to the vehicle
speed . This is most noticeable when turning the steering wheel at
low speeds (for example when parking), -more effort will be
required than usual.

Alway s adjust your driving to road and traffic condition s. Do not
let the extra safety afforded by the all -wheel drive tempt you into
taking extra risks .
• Although the quattro ®all-wheel drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at e xcessive speeds on icy or slippery
road surfaces.
• On wet road surfaces , be careful not to drive too fast be cause
the front wheels could begin to slide on top of the water (hydro ­
planing ). If this should occur , you will have no warning from a
sudden increase in engine speed as with a front -wheel drive
vehicle . Always drive at speeds which are adjusted to the road
conditions - risk of crash! •

crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead means the part of the tire that is made of steel wires, wrapped or
reinforced by ply cords and that is shaped to fit the rim.
Bead separation
means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
&, WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage.
•
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted .
Curb weight
means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire designed to operate at higher loads and at higher infla ­
tion pressures then the corresponding standard tire. Extra load tires
my be identified as "XL", "xi", "EXTRA LOAD", or
"RF" on the side ­
wall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire-ground interfaces .
Gross Vehicle Weight Rating ("GVWR")
means the maximum total loaded weight of the vehicle.

& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators .
• Especially in wet and slick driving situations , a preferably large
profile depth of the tires is necessary , and an approximately
similar profile depth of the front and rear axle tires.
• The diminished driving safety , caused by too small of a tire
profile, is negatively perceivable especially in handling , in danger
of hydroplaning when driving through deep puddles and ponds,
when driving around curves , and in braking behavior.
• Worn tires are a safety hazard , they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chem icals that can cause tire damage , such as
grease, oil, gasoline and brake fluid away from tires .
• Tires age even if they are not being used and can fail suddenly ,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds .
