- Do not press back the bonnet unless both of
your hands are flat on top of the bonnet. If
you do this, you cannot catch your fingers
between the bonnet and body. Take care
when pressing back the bonnet: careless or
uncontrolled movements can cause injury to
yourself or others -risk of injury!
- The system can only be activated once. If
the pedestrian protection system has been
triggered, have it replaced without delay by
a qualified workshop.
- All repairs to the bumper and the pedestrian
protection system must only be carried out
by a qualified workshop working to the
spe cifications of the Audi factory. Improper
repairs can impair the effectiveness of the
system and invalidate the operating permit
for your vehicle.
- The relevant safety requirements must be
observed when individual components of
the system or the entire vehicle are scrap­
ped. Your authorised dealer is familiar with
these regulations and will be pleased to
pass on the information to you.

Do not wear the belt over hard or fragile ob­
jects (such as glasses or pens, etc.) because
this can cause injuries.
- Loose, bulky clothing (such as an overcoat
over a jacket) impairs the proper fit and
function of the belts.
- The belts must be kept clean, otherwise the
retractors may not work properly
¢ tab. Cleaning the interior on page 238.
- The slot in the seat belt buckle must not be
blocked with paper or other objects, as this
can prevent the latch plate from engaging
properly.
- The latch plate of the belt must always be
engaged in the correct buckle for that seat,
otherwise the belt will not be fully effective.
- Check the condition of the seat belts at reg­
ular intervals. If you notice that the belt
webbing, fittings, retractor mechanism or
buckle of any of the belts is damaged, the
belt must be replaced by a qualified work­
shop.
- The seat belts must not be removed or
modified in any way. Do not attempt to re­
pair a damaged belt yourself.
- Seat belts which have been worn in an acci­
dent and stretched must be replaced by a
qualified workshop. The belt anchorages
should also be checked. Seat

Forces acting in a
collision
The physical principles involved in a frontal
impact
Very large forces are generated during a colli­
sion; these forces have to be absorbed.
Fig. 184 Passengers of a vehicle which is headed for a
brick wall. They are not using seat belts.
Fig. 185 The vehicle crashes against the wall
The phys ical principles involved in a frontal colli­
sion are relatively simple:
Both the moving vehicle and the passengers pos­
sess energy, which is known as "kinetic energy"
¢ Fig. 184. The amount of "kinetic energy" de­
pends on the speed of the vehicle and the weight
of the vehicle and passengers. The higher the
speed and the greater the weight, the more ener­
gy there is to be absorbed in an accident.
The most significant factor, however, is the speed
of the vehicle. If the speed doubles from 25 km/
h to 50 km/h, for example, the kinetic energy in­
creases by a factor of four. Because these passen­
gers are not restrained by seat belts, the entire
amount of kinetic energy has to be absorbed at
the point of impact ¢ Fig. 185. This would result
in serious or potentially fatal injury.

belts
Even at urban speeds of 30 km/h to 50 km/h, the
forces acting on the occupants in a collision can
reach the equivalent of 1 ton (1000 kg) or more.
At greater speed these forces are even higher.
Again: if the speed doubles, the forces increase
by a factor of four.
Passengers who do not wear seat belts are not
"attached" to the vehicle. In a frontal collision
they will continue to move forward at the speed
their car was travelling just before the impact.
What happens to passengers not wearing
seat belts?
Passengers not wearing seat belts risk fatal inju­
ries in the event of an accident.
Fig. 186 A driver not wearing a seat belt can be thrown
forwards
Fig. 187 A rear passenger not wearing a seat belt can be
thrown forwards
In a frontal collision, unbelted passengers will be
thrown forwards and make violent contact with
the steering wheel, dashboard, windscreen, etc
¢ Fig
. 186.
Passengers not wearing their belts
risk being thrown out of the car. This could result
in potentially fatal injuries.
The common belief that occupants can brace
their weight with their hands in a minor collision
206 is
false. Even at low speeds the forces acting on
the body in a collision are so great that it is not
possible to hold yourself in the seat.
It is also important for the rear passengers to
wear seat belts, as they could otherwise be
thrown forwards violently in an accident. Rear
passengers who do not use seat belts endanger
not only themselves but also the other occupants

.... The
three-point inertia reel belts are tensioned
automatically. The retractor system gives com­
plete freedom of movement, as long as the pull
on the belt is slow. Hard braking locks the belt.
The belt will also lock when you accelerate, drive
up or down a steep hill or in a sharp curve.
A WARNING
- Always make certain that the belt is posi­
tioned properly ¢ Fig. 188 -risk of injury
¢ page 207, Adjusting the seat belts.
- The latch plate of the belt must always be
engaged in the correct buckle for that seat.
Otherwise the belt will not be fully effective
and the danger of injury increases.
Adjusting the seat belts
Always position seat belts properly for maximum
safety.
Fig. 190 Adjusting shoulder/lap belt
The following equipment is available for your ve­
hicle to help you position the seat belt properly
to suit your height:
- Seat height adjustment (front seats)
A WARNING
- The shoulder section of the belt should be
fitted across the centre of the collar bone
close to the body. To fasten the belt, take
hold of the belt above the latch plate and
pull it slowly down across your chest. Wear
the lap portion of the seat belt as low as
possible over the hips so that there is no
pressure on the lower abdomen. The belt
should always be worn tightly¢ Fig. 190 . Seat
belts
Pull the belt tight if necessary to take up
any slack.
- Always make sure that belt is positioned
properly. Incorrectly worn seat belts can
give rise to injuries even in a minor collision.
- Seat belts worn too loose can result in inju­
ries because they allow excessive forward
movement in a crash; the occupant will be
brought to a sudden stop by the belt web­
bing.
Wearing and adjusting the seat belts
during pregnancy
To afford the best protection for the unborn
child it is important for the mother to wear the
seat belt properly at all times.
Fig. 191 Positioning seat belts during pregnancy
Women should always ensure they adjust the
seat belt correctly during pregnancy.
� Adjust the front seat correctly before putting
on the seat belt¢ page 46, Seats and storage.
� To
fasten the belt, take hold of the latch plate
and pull it slowly down across your chest. Wear
the lap portion of the seat belt as low as possi­
ble over the hips so that there is no pressure on
the stomach ¢ Fig. 191, ¢ ,&. .
� Insert the latch plate into the buckle for the ap­
propriate seat and push it down until it is se­
curely locked with an audible click¢ page 206,

.... Airbag
system
Description of airbag
system
General notes on airbag system
The airbag is an integral part of the car's passive
safety system.
In conjunction with the seat belts, the airbag sys­
tem gives the front occupants additional protec­
tion for the head and chest in the event of a se­
vere frontal collision.
In a side collision the side airbags reduce the risk
of injury to the areas of the body facing the im­
pact ¢_&.
In addition to their normal function of protecting
the occupants in a collision, the seat belts also
hold them in a position where the airbags can in­
flate properly and provide maximum protection.
The airbag system will only work with the igni­
tion on. The airbag system is monitored electron­
ically; the airbag warning lamp indicates whether
the system is functioning properly.
The main parts of the airbag system are:
- The electronic monitoring system (control unit
and sensors)
- The two front airbags
- The two side airbags
- The warning lamp El in the instrument cluster
There is a fault in the airbag system if the
warning lamp
- does not come on when the ignition is switched
on.
- does not go out about 4 seconds after the igni­
tion is switched on.
- goes out and then comes on again after the ig­
nition is switched on.
- comes on or flickers while the car is moving.
A WARNING
- The airbags are not a substitute for the seat
belts; they are an integral part of the car's
overall passive safety system. The airbags
can only offer effective protection if the oc- Airbag system
cupants are wearing their seat belts. For
this reason it is very important to wear the
seat belts at all times ¢ page 204, Why is it
so important to use seat belts?.
- The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly ¢ page 46, Seats and stor­
age.
- If you do not wear a seat belt, if you lean
for ward, or are not seated correctly while
the vehicle is in motion, you are at greater
risk of injury should the airbag system be
triggered in an accident.
- Components of the airbag system are loca­
ted in various parts of the vehicle. If repairs
to other vehicle components make it neces­
sary to perform work on the airbag system
or to remove or install parts of the airbag
system, this may cause damage to the air­
bag system. As a result, the airbags may not
inflate correctly or may not be triggered at
all in an accident situation. For this reason,
you should always have the work carried out
by a qualified workshop.
- If a fault should occur in the airbag system,
have the system checked immediately by a
qualified workshop. Otherwise the system
may fail to trigger in an accident.
- Do not attempt to modify components of
the airbag system in any way.
- Never make any alterations to the front
bumper or the body.
- Do not remove the front seats.
- The airbag system can only be activated
once; if the airbag has been triggered, the
system must be replaced. Should the airbag
system or airbag modules have to be re­
placed, the qualified workshop carrying out
the replacement will document all details.
- If you sell the vehicle, remember to pass on
the complete Service Wallet to the new
owner. If any of the airbags have been deac­
tivated, it is important that the new owner
is also given the relevant documents.
- The relevant safety requirements must be
observed when the vehicle or components
of the airbag or belt tensioner systems are
scrapped.

Fuel Petrol grade
Applies to vehicles: with petrol engine
The correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic converter
and must only be run on unleaded petrol. The
petrol must comply with the EN 228 or DIN
51626-1 standard and must be sulphur-free. You
can fuel your vehicle with fuels containing a max­
imum of 10% ethanol (ElO). The petrol grades
have different octane ratings (RON).
The following headings relate to the sticker on
the inside of your vehicle's tank flap:
Unleaded fuel only RON/ROZ 95 Super,
Premium or min. RON/ROZ 91 Normal
The use of premium petrol (95 RON) is recom­
mended. If that type of fuel is not available, reg­
ular petrol (RON 91) can be used with a slight
loss of power.
Unleaded fuel only, min. RON/ROZ 95 Super,
Premium
Premium petrol (at least 95 RON) must be used.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an emer­
gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi­
ble.
Unleaded fuel only RON/ROZ 98 Super Plus
or min. RON/ROZ 95 Super, Premium
The use of Super Plus petrol (98 RON) is recom­
mended. If that type of fuel is not available, pre­
mium petrol (RON 95) can be used with a slight
loss of power.
If premium petrol is not available, the engine can
� be
run on regular petrol with 91 RON as an emer-

CD CAUTION
- Do NOT fuel your vehicle with high-ethanol
fuel blends (e.g. ESQ or E85). This will dam­
age the fuel system.
- Just one tank of leaded fuel or fuel with
metallic additives will permanently impair
the efficiency of the catalytic converter.
- You should use only petrol additives which
have been approved by Audi. Additives with
so-called octane boosters or antiknock addi­
tives can contain metallic additives that
cause significant damage to the engine and
the catalytic converter. Do not use such ad­
ditives.
- Metal-based fuels, which can be identified
from the marking on the fuel dispenser,
must not be used. LRP fuel (lead replace­
ment petrol) also contains high concentra­
tions of metallic additive. Risk of engine
damage!
- High engine speed and full throttle can
damage the engine when using petrol with
an octane rating lower than the correct
grade for the engine.
«'.D Note
- You can use higher octane fuel than your en­
gine requires.
- In countries where sulphur-free fuel is not
available, you may use low-sulphur fuel in­
stead.
Diesel fuel
Applies to vehicles: with diesel engine
Please note the information on the inside of the
fuel tank flap.
The use of sulphur-free diesel to EN 590 is rec­
ommended. If that type of fuel is unavailable,
diesel to EN 590 can be used. It must have ace­
tane number (CN) of at least 51. The cetane
number indicates the ignition quality of the die-
sel fuel.

Downloaded from www.Manualslib.com manuals search engine Checking
and topping up fluids
Diesel can thicken at very low temperatures,
which can result in problems starting the engine
or prevent the engine from running smoothly. For
this reason, filling stations in some countries of­
fer winter-grade diesel fuel during the cold
months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth­
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
CD CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam­
age to the fuel system and the engine.
- Never start the engine if you fill up with the
wrong type of fuel, as this could damage
the fuel system and the engine. Obtain pro­
fessional assistance.

Press the tank flap -arrow- ¢ Fig. 204 to open
it. Your vehicle has a new self-sealing fuel tank
without a tank cap.
� Insert the filler nozzle into the fuel filler neck
as far as the stop ¢ Fig. 205 and ensure it is
properly engaged.
� Start refuelling. When the automatic filler noz­
zle is operated correctly it will switch itself off
as soon as the tank is "full". Do not try to put in
more fuel after the nozzle cuts out, as this will
fill the expansion chamber in the fuel tank.
� When the fuel filler pump switches itself off,
wait for 5 seconds before pulling out the filler
nozzle so that any remaining fuel can flow into
the tank opening.
� Close the tank flap. Make sure you hear it click
into place.
The correct fuel grade for your vehicle is given on
a sticker on the inside of the tank flap. Further
notes on fuel ¢page 217.
The tank capacity of your vehicle is given in the
Technical data section ¢ page 258.
& WARNING
Fuel is highly inflammable and can cause seri­
ous burns and other injuries.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and leak.
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- When filling your tank or a spare fuel canis­
ter with fuel, do not smoke and keep away
from naked flames -risk of explosion!
- If,
in exceptional circumstances, you have to
carry a spare fuel canister, please observe
the following warnings:
- Never fill fuel into the spare fuel canister
with the canister placed in or on top of the
vehicle. An electrostatic charge could
build up during filling, causing the fuel va­
pour to ignite -risk of explosion! Always
place the canister on the ground to fill it.
- Insert the filler nozzle as far as possible
into the spare fuel canister.

.... -
If the spare fuel canister is made of metal,
the filler nozzle must be in contact with
the canister during filling. This helps pre­
vent an electrostatic charge building up.
- Make sure you never spill fuel in the vehi­
cle or in the Luggage compartment. Fuel
vapour is explosive -danger to Life!
CD CAUTION
- Remove any fuel spills from the paintwork
immediately.
- Never run the tank completely dry. If there
is an irregular fuel supply, misfiring can oc­
cur. As a result unburnt fuel can enter the
exhaust system and cause damage to the
cata Lytic converter(s).
- When filling the fuel tank after having run it
completely dry on a vehicle with a diesel en­
gine the ignition must be switched on for at
Least 30 seconds without starting the en­
gine. When you then start the engine it may
take Longer than normal (up to one minute)
for the engine to start firing. This is because
air needs to be bled from the fuel system
while starting.
(® For the sake of the environment
Do not overfill the fuel tank -this may cause
the fuel to overflow if it becomes warm.
(1j) Note
Should the fuel tank flap become frozen stuck
during inclement weather, press the middle
of the flap with the palm of the hand and try
again.
@ Note
To prevent the tank from being filled with the
incorrect type of fuel (petrol or diesel), only
suitable filler nozzles can be inserted in the
fuel filler on your vehicle.
- If the filler nozzle is old, damaged or too
small, it may not be able to open the pro­
tection mechanism on the fuel tank. In this
case, try turning the filler nozzle before in­
serting it in the fuel filler neck, use a differ- Checking

tance.
- The protection mechanism will not open if
you try to add fuel from a spare fuel canis­
ter. If you need to fill the tank from a spare
