Important safety notes on the side airbag system
There are a number of safety points concerning the airbag
system which you should remember. This will help to
reduce the risk of injury in an accident.
WARNING
•
If you do not wear a seat belt, if you lean forward, or are not
seated correctly while the vehicle is in motion, you are at greater
risk of injury should the side airbags be triggered in an accident.
•
If children are not seated correctly, they are at greater risk of
injury in an accident. This is particularly the case if the child is
travelling on the front passenger's seat and the airbag system is
triggered. This could result in serious or potentially fatal injury
⇒page 185, “Child safety”.
•
It is important not to attach any accessories (such as cup
holders) to the doors. This would impair the protection offered by
the side airbags.
•
The sensors for the airbags are located in the front doors. You
must therefore not make any modifications to the doors or door
trim (e.g. retrofitting loudspeakers), as this could impair the func-
tion of the side airbags. Any damage to the front doors could lead
to faults in the system. Repairs or any other work on the front
doors must therefore always be carried out by a qualified work-
shop.
•
The built-in coat hooks should only be used for lightweight
clothing. Do not leave any heavy or sharp-edged objects in the
pockets.
•
Do not apply excessive force to the sides of the backrests (such
as hard knocks or kicks), as this could damage parts of the system.
The side airbags could then fail to operate when required.
•
If you intend to fit protective covers over the seats, these must
be of the specific type approved for use on Audi seats with side
airbags. Conventional seat covers would obstruct the side airbag when it inflates out of the backrest, and seriously reduce the
airbag's effectiveness.
•
Any damage to the original seat upholstery or around the
seams of the side airbag units must be repaired immediately by a
qualified workshop.
•
Any work involving the side airbag system or removal and
installation of the airbag components for other repairs (such as
repairs to the seats) must always be performed by a qualified
workshop. Otherwise the airbag system may fail to work
properly.
Head-protection airbags (sideguard)Description of head-protection airbags
The head-protection airbags work together with the side
airbag system to give extra protection in a side impact.The head-protection airbags are located above the doors on the left
and right sides of the vehicle ⇒fig. 193. The locations of the airbags
are marked with the word “AIRBAG”.

•
Where sun blinds are fitted on the rear doors, these must not
obstruct or impair the airbags in any way.
•
If unsuitable accessories are installed near the head-protection
airbag, the protection afforded by the airbag can be seriously
impaired if the system is triggered. When the head-protection
airbag opens, parts of these accessories could be thrown into the
vehicle and injure passengers ⇒page 250.
•
Any work involving the head-protection airbags, or removal
and installation of the airbag components for other repairs (such
as repairs to the roof liner), must always be performed by a quali-
fied workshop. Otherwise the airbag system may fail to work
properly.
Applies to vehicles: with key-operated switch for front passenger's airbagDeactivating the front passenger's airbag via the key-operated switchIf an airbag has been deactivated, it should be reactivated
as soon as possible so that it can continue to give the
required protection.The key-operated switch for deactivating the front

Child safetyPoints to remember if children are
travelling in the carIntroduction
Statistics show that children are generally safer on the
rear seat than on the front passenger's seat.Children under 12 years of age should normally travel on the rear
seat
4). Children travelling on the rear seat must use a child restraint
system or the seat belts provided, depending on their age, height
and weight. For safety reasons, the child restraint system should be
installed behind the front passenger's seat.
The physical principles involved and the forces acting in a collision
apply to children just as much as adults ⇒page 171, “Forces acting
in a collision”. But, unlike adults, children do not have fully devel-
oped muscle and bone structures. This means that children are
subject to a greater risk of injury.
To reduce this risk, children must always use special child restraint
systems when travelling in the car.
Use only child restraint systems which are officially approved under
the European standard ECE R 44 and are suitable for the child. ECE R
refers to the Economic Commission of Europe Recommendation,
which categorises child restraint systems in 5 groups ⇒page 186,
“Child seat categories”. Child restraints that have been tested and
approved under the ECE R 44 standard bear the ECE-R 44 test mark
on the seat (the letter E in a circle with the test number below it).
We recommend using child restraint systems from the range of
Audi Genuine Accessories available from Audi dealers. The
“Huckepack” range includes suitable restraint systems for all ages. These systems have been specially developed and tested for use in
Audi vehicles and comply with the ECE-R 44 standard.
Follow the manufacturer's instructions and observe any statutory
requirements when installing and using child restraints ⇒ in
“Important safety notes for using child safety seats”.
Important safety notes for using child safety seats
Correct use of child safety seats can help to reduce the
risk of injury in an accident.
WARNING
•
All vehicle occupants, especially children, must wear a seat
belt while the vehicle is in motion.
•
Children who are less than 1.5 metres tall must not wear a
normal seat belt without a child restraint, as this could cause inju-
ries to the abdominal and neck areas.
•
Babies and children must never travel on another occupant's
lap.
•
A suitable child safety seat can protect your child ⇒page 186,
“Child safety seats”.
•
Never allow two children to occupy one child safety seat.
•
Never leave a child without supervision in a child safety seat.
•
Never allow a child to travel in the car without a suitable child
restraint.
•
Never allow a child to stand up or kneel on a seat while the car
is moving. In an accident, the child could be catapulted through
the car, causing possibly fatal injuries to itself and other occu-
pants.
4)Observe any restrictions or regulations to the contrary.

Possible alternatives for securing a child safety seat
A child safety seat can be secured on the rear seats and
on the front passenger's seat.The following alternatives are available for safely securing a child
safety seat on the rear seats and on the front passenger's seat.•
Child safety seats of the categories 0 to 3 can be secured with the
standard three-point seat belts.
•
Child safety seats of the categories 0, 0+ and 1 with the “ISOFIX”
system can be secured without seat belts using the “ISOFIX”
retainers* ⇒page 191.
Compatibility of vehicle seat positions for child safety seats
(according to EC directive 77/541):
“universally compatible”
The front passenger's backrest must be set as far forward as
possible or adapted to the child safety seat as required, and the
seat height must be adjusted to its highest position.
The front passenger's airbag must be deactivated if a rearward-
facing child seat is used.
The front passenger's seat can be equipped with optional
“ISOFIX” retainers.
The rear seats can be equipped with optional “ISOFIX” retainers.
WARNING
While the vehicle is moving, children must always be protected
with a restraint system which is suited to their age, height and
weight. Please refer to the chapter “Child seat categories”.•
Never install a rearward-facing child safety seat on the front
passenger's seat unless the front passenger's airbag has been
deactivated. This could result in potentially fatal injuries. If you
have no alternative but to let a child travel on the front passenger's
seat, the front passenger's airbag must be deactivated before-
hand. Please refer to the chapter “Deactivating airbags”.
•
Note the important information and warnings concerning the
use of child safety seats found in the chapter “Important safety
notes when using child safety seats” and in the installation
instructions provided by the manufacturer of the child safety
seat.

Technical data Switching off
The ESP should normally be left switched on at all times. If required,
you can press the ESP OFF button to switch off the traction control
system (ASR) or the electronic stabilisation program (ESP).
•
Switching off the traction control system (ASR): Press the ESP
button briefly. The traction control system (ASR) can be switched off
in special driving conditions, e.g. if you are driving with snow chains
⇒page 198. The message ASR off will appear in the display.
•
Switching off the ESP/traction control system (ASR): Press the
ESP button for longer than 3 seconds. The ESP/ASR warning lamp
lights up when the system is switched off, see ⇒page 16. The
message ESP switched off will appear in the display.
WARNING
•
The ESP is not able to overcome the physical limits of adhesion.
Even with ESP, you should always adjust your speed to suit the
conditions. Please bear this in mind, especially on wet or slippery
road surfaces. Do not let the extra safety provided tempt you into
taking any risks when driving – this can cause accidents.
•
Please note that, when the ESP or ESP/traction control system
(ASR) is switched off, the driven wheels may start to spin, causing
the vehicle to lose grip, in particular on slippery or wet roads -
danger of skidding!
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking.The anti-lock brake system (ABS) is an important part of the car's
active safety system. However, the ABS will not necessarily guar-
antee shorter stopping distances in all conditions. For instance, on
loose gravel or fresh snow on top of an icy surface (conditions which
anyway require extreme care and reduced speed), the stopping
distance with ABS may even be slightly longer.How the ABS works
The system runs an automatic self-check when the car reaches a
road speed of about 6 km/h. This may be accompanied by a noise
from the ABS pump.
If one of the wheels is turning too slowly in relation to the road
speed, and is close to locking up, the system will reduce the pres-
sure in the brake line to this wheel. The driver is made aware of this
control process by a pulsating of the brake pedal and accompa-
nying noise. This is a deliberate warning to the driver that one or
more of the wheels is tending to lock up and the ABS control func-
tion has intervened. In this situation it is important to keep the brake
pedal fully depressed so the ABS can regulate the brake application
- do not “pump” the brake pedal.
WARNING
The grip provided by ABS is still subject to the physical limits of
adhesion. Always bear this in mind, especially on wet or slippery
roads. If you notice that the ABS is working (to counteract locked
wheels under braking), you should reduce speed immediately to
suit the road and traffic conditions. Do not let the extra safety
provided tempt you into taking any risks when driving – this can
cause accidents.
Note
If a malfunction should occur in the ABS, this is indicated by a
warning lamp ⇒page 18.Brake assist system
The brake assist system helps the driver to achieve
optimum braking effect.The brake assist system helps to increase braking power and thus to
achieve a shorter stopping distance. If the driver presses the brake
