Fastening rings
Unsecured loads are a hazard to all vehicle occu­
pants.
Fig. 180 Location of fastening rings in luggage compart­
ment
.,. Use the fastening rings to secure items safely in
the luggage compartment ¢ A in Luggage
compartment on page 201.
During a collision or an accident, even small and
light objects can possess so much energy that
they can cause very severe injuries. The amount
of this "kinetic energy" depends on the speed of
the vehicle and the weight of the object. The
most significant factor, however, is the speed of
the vehicle.
For example: an object weighing 4.5 kg is lying
unsecured in the vehicle. During a frontal colli­
sion at a speed of SO km/h, this object generates
a force corresponding to 20 times its weight.
That means that the effective weight of the ob­
ject increases to about 90 kg. You can imagine
the severity of the injuries which might be sus­
tained if this "projectile" strikes an occupant as it
flies through the passenger compartment.
A WARNING
If items of luggage or other objects are se­
cured to the fastening rings with inappropri­
ate or damaged tensioning straps, injuries
could result in the event of sudden braking or
a collision.
- To prevent pieces of luggage or other ob­
jects from flying forward, always use appro­
priate tensioning straps which are properly
secured to the fastening rings.
202 -
Never secure a child seat on the fastening
rings.
Pedestrian protection
system
Description
Applies to vehicles: with pedestrian protection system
The pedestrian protection system will automati­
cally be activated when the front of the vehicle
collides with a pedestrian. The bonnet is raised
several centimetres to create an additional crush
zone above the engine.
The sensors of the pedestrian protection system
are located in the front bumper. In rare cases, the
system can be triggered because the possibility
that a pedestrian has been hit cannot be ruled
out by the sensors, for example:
- in a coll ision with a street post,
- in a collision with an animal, or
- if you drive into a pile of snow, or
- in the event of ground contact, e.g. when driv-
ing on extremely poor road surfaces.
If the system has been activated, press the bon­
net back into its original position¢&. in Servic­
ing the pedestrian protection system on
page 203 and have the system serviced by a
qualified workshop.
.&_ WARNING
- Never change or replace the bumper or bon­
net as a part of tuning measures. This can
impair the effectiveness of the pedestrian
protection system and invalidate the operat­
ing permit for your vehicle. The manufactur­
er cannot be held liable for damage which
occurs as a result of failure to comply with
these stipulations, and such damage is not
covered under warranty.
- False activation of the pedestrian protection
system is possible.

belts
Seat belts
Why is it so important to
use seat belts?
Seat belts provide effective protection
The common belief that passengers can brace
their weight with their hands in a minor collision
is false.
Fig. 183 Driver with properly positioned seat belt -good
protection if the brakes are applied suddenly
It is an established fact that seat belts provide
good protection in accidents. Therefore wearing a
seat belt is required by law in most countries.
Properly worn seat belts hold the occupants in
the best position for maximum protection
¢ Fig. 183. The seat belts are capable of absorb­
ing much of the kinetic energy arising in a colli­
sion. Also they help to prevent uncontrolled
movements which could lead to severe injuries
¢ page 204, Important safety notes when using
seat belts.
If they wear the seat belts correctly, the passen­
gers benefit greatly from the ability of the belts
to reduce the kinetic energy gradually. The front
crumple zones and other passive safety features
(such as the airbag system) are also designed to
absorb the kinetic energy generated in a collision.
Taken together, all these features reduce the
forces acting on the occupants and consequently
the risk of injury.
Although these examples are based on a frontal
collision, the physical principles involved are the
same in other types of accidents. This is why it is
so import ant to put on the seat belts before ev­
ery trip -even when "just driving around the cor-
204 ner".
Ensure that your passengers wear their seat
belts as well ¢ ,&.
Properly worn seat belts have been shown to be
an effective means of reducing the potential for
injury and improving the chances of survival in a
serious accident ¢ page 205, Forces acting in a
collision.
For information on how children can travel safely
in the car refer to¢ page 195, Child seats .
.lD.. WARNING
- Seat belts must be put on before every trip -
even when driving in town. This also applies
to the rear passengers -risk of injury!
- During pregnancy, women should always en­
sure they wear a seat belt. The best way to
protect the unborn child is to protect the
mother ¢ page 207, Wearing and adjust­
ing the seat belts during pregnancy.
Important safety notes when using seat
belts
There are a number of safety points concerning
the seat belts which you should remember. This
will help to reduce the risk of injury in an acci­
dent.
.lD.. WARNING
- The seat belts can only provide maximum
protection if the seats are adjusted properly
¢page 46, Seats and storage.
- To ensure proper protection, it is important
to wear the seat belts in the correct position
¢ page 206, How to wear seat belts prop­
erly. Ensure that the seat belts are worn ex­
actly as recommended in this chapter. Belts
which are not worn properly can increase
the risk of injury in accidents considerably.
- Do not allow the seat belt to become twis­
ted or jammed, or to rub on any sharp
edges.
- Never allow two passengers (even children)
to share the same seat belt. It is especially
dangerous to place a seat belt over a child
sitting on your lap.

_& WARNING
During pregnancy, women should especially
make sure to wear the lap portion of the seat
belt as low as possible across the hips so that
there is no pressure on the stomach.
Taking off the seat belts
The red button releases the belt from the buckle.

• Press the red button in the seat belt buckle
¢ Fig. 192. The latch plate will spring out of
the buckle.
• Guide the belt back by hand so that it is taken
up by the retractor.
Belt tensioners
How the belt tensioners work ,...
N
0
' a:l
The seat belts for the driver and front passenger
are equipped with belt tensioners.
The seat belts on the front seats are tensioned
automatically in frontal, side and rear-end im­
pacts above a certain degree of severity. This
helps to reduce the forward motion of the occu­
pants.
In a less severe accident, or in the event of a roll­
over, the belt tensioners are not activated.
_& WARNING
- Any work on the tensioner system or remov­
al and installation of system components
for other repairs must be performed by a
qualified workshop.
208 -
The belt tensioners can only be activated
once. If they have been activated at any
time, the system must be replaced.
({D Note
- Some smoke may be released when the belt
tensioners are activated. This does not
mean there is a fire in the vehicle.
- The relevant safety requirements must be
observed when the vehicle or components
of the system are scrapped. Your authorised
dealer is familiar with these regulations and
will be pleased to pass on the information
to you.

Downloaded from www.Manualslib.com manuals search engine Airbag
system
- For safety reasons, the alternator and the
starter are both disconnected from the bat­
tery via a pyrotechnic circuit breaker in se­
vere accidents.
-Any repairs to the pyrotechnic circuit
breaker must always be performed by a
qualified workshop - risk of accident!
- The relevant safety requirements must be
observed when the vehicle or the circuit
breaker are scrapped.
When are the airbags triggered?
One or more airbag systems are triggered in se­
vere collisions, depending on the circumstances.
The airbag system is not triggered in minor colli­
sions, or in rear collisions, or if the car overturns.
In these situations, the occupants are protected
by wearing the seat belts.
Factors determining the triggering response
It is not possible to define the exact triggering
response of the airbag system in all possible sit­
uations, since the circumstances in different
types of accident will vary considerably. Impor­
tant factors include, for example, the nature
(ha rd or soft) of the object which the car hits, the
angle of impact, vehicle speed and so on.
Whether the airbags are triggered depends pri­
marily on the vehicle deceleration rate resulting
from the collision. By processing the signals from
the sensors located in the vehicle, the electronic
control unit is immediately able to evaluate the
severity of the collision and activate the restraint
systems accordingly. If the deceleration rate is
below the predefined reference value in the con­
trol unit the airbags will not be triggered, even
though the accident may cause extensive damage
to the car.
([J) Note
The airbag releases a fine dust when it in­
flates. This is quite normal and does not
mean there is a fire in the vehicle.

and tyres
Wheels General notes
... Inspect the tyres regularly for damage (cuts,
cracks or blisters, etc.). Remove any foreign
bodies embedded in the treads.
... If you have to drive over a kerb or similar obsta­
cle, drive very slowly and as near as possible at
a right angle to the kerb.
... Damaged rims or tyres must be replaced imme­
diately.
... Keep grease, oil and fuel off the tyres.
... Mark
the wheels before taking them off so that
they rotate in the same direction when refitted.
... When removed, the wheels should be stored
flat in a cool, dry and preferably dark place.
CD CAUTION
- Please note that summer and winter tyres
are optimised for the prevailing road condi­
tions at different times of year. We recom­
mend that you use winter tyres during the
winter months. At low temperatures, sum­
mer tyres lose their elasticity and grip, and
braking performance also suffers as a re­
sult. Cracks can form in the tread block on
summer tyres if they are used at very cold
temperatures, and this can cause perma­
nent damage to the tyres. An increase in
rolling noise and tyre imbalance may result
from this damage.
- Machined, polished or chrome-plated rims
must not be used in winter conditions. The
process used to manufacture these types of
wheel rim does not provide adequate sur­
face protection against corrosion, and the
rims can be permanently damaged by road
salt or similar.
New wheels or tyres
It is best to have all servicing of wheels and tyres
performed by a qualified workshop, since they
have the necessary special tools and replacement
parts and trained personnel. Wheels
and tyres
... New tyres do not yet give maximum grip. When
driving with new tyres, drive at moderate
speeds and be especially careful during the first
500 km.
... All four wheels must be fitted with tyres of the
same type, size (rolling circumference) and
preferably the same tread pattern.
... Tyres should be replaced in pairs and not indi­
vidually (i.e. both front tyres or both rear tyres
together).
... We recommend the use of Audi Genuine Tyres.
If you wish to use other tyres, please note that
the actual size can differ from the nominal size
marked on the tyre ¢.&_
.
... If you wish to purchase a different combination
of rims and tyres than the ones fitted on the ve­
hicle during production, it is advisable to con­
sult a qualified workshop beforehand ¢.&_
.
On vehicles with four-wheel drive, all four wheels
must always be fitted with tyres of the same
type, make and tread pattern, as otherwise the
driveline can be damaged by variations in the
wheel speeds. For the same reason, only use a
spare wheel* which has the same rolling circum­
ference as the normal road wheels.
If the spare wheel* is not the same type as the
tyres fitted on the car (for example if the car has
winter tyres or wide-section tyres) you should on­
ly use the spare wheel* if a puncture occurs, and
then only for a short period of time. In this case,
please drive with extra care. Refit a normal road
wheel as soon as possible.

Care of vehicle and
cleaning
General notes
Regular and careful care helps to maintain the
value of the vehicle. This may also be one of the
requirements for upholding any warranty claims
in the event of corrosion or paint defects.
The required car care products are available from
Audi dealers or specialist retailers. Please follow
the instructions for use on the packaging.
A WARNING
- Cleaning products and other materials used
for car care can damage health if misused.
- Car care products can contain toxic substan­
ces and must always be kept in a safe place
out of reach of children.
®, For the sake of the environment
- Please choose care products that are not
harmful to the environment.
- Surplus cleaning materials should not be
disposed of together with ordinary house­
hold waste.
Washing the vehicle
The longer residues are allowed to remain on the
vehicle, the more damage they can do to the
paintwork. High temperatures (for instance in di­
rect sunlight) further intensify the damage.
Before washing, soak heavy dirt with plenty of
water.
Stubborn dirt, such as bird droppings or resinous
tree sap, is best removed with plenty of water
and a micro-fibre cloth.
After the period when salt is put on the roads,
have the underside of the vehicle washed thor­
oughly.
High-pressure cleaners
When cleaning the vehicle with a high-pressure
cleaner, always follow the operating instructions
for the equipment. This applies particularly to
236 the
operating pressure and the spraying distance.
Do not point the spray jet directly at the seals on
the windows, doors, bonnet or boot lid, or at the
tyres, rubber hoses, insulating material or sen­
sors*. Maintain a distance of at least 40 cm.
Do not use a high-pressure cleaner to remove
snow and ice.
Never use high-pressure cleaners with a round-jet
nozzle or "dirt blasters".
The water must not be hotter than 60 °C.
Automatic car washes
Spray the vehicle with water before washing.
Ensure that the windows are closed and that the
windscreen wipers are switched off. Follow the
car wash operator's rules and recommendations,
especially if any accessories are attached to your
vehicle.
If possible use a brush less car wash.
Washing by hand
Clean the car with a soft sponge or brush, start­
ing on the roof and working down. Use solvent­
free cleaning agents.
Washing matt-painted vehicles by hand
To avoid damaging the paintwork when washing
the car, first remove any dust, sand and grit. In­
sects, grease stains and fingerprints are best re­
moved using a special cleaning agent for matt­
painted surfaces.
Apply the product with a micro-fibre cloth. Do
not apply too much pressure to avoid damaging
the paintwork.
Rinse the car thoroughly with water. Then clean
the car with a neutral shampoo and a soft micro­
fibre cloth.
Rinse the car with lots of water again and then
let it dry in the air. Remove any water stains with
a chamois.
