(e.g. retrofitting loudspeakers), as this
could impair the function of the side air­
bags. Any damage to the front doors could
lead to faults in the system. Repairs or any
other work on the front doors must there­
fore always be carried out by a qualified
workshop.
- 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 ap­
proved for use on Audi seats with side air­
bags. Conventional seat covers would ob­
struct the side airbag when it inflates out of
the backrest, and seriously reduce the air­
bag'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 com­
ponents 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
Description of head-protection airbags
Applies to vehicles: with head-protection airbags
Fig. 202 Location of head-protection airbag above the
door
The head-protection airbags are located above
the doors on the left and right sides of the vehi- Airbag
system
de ¢Fig. 202. The locations of the airbags are
marked with the word "AIRBAG".
In conjunction with the three-point seat belts
and side airbags, the head-protection airbags
give the occupants additional protection against
head and neck injuries in a severe side collision
¢.&. in Important safety notes on the head-pro­
tection airbags on page 216.
Together with other design features (including
cross-braces in the seats and the overall strength
of the body structure), the head-protection and
side airbag system offers an effective further im­
provement to occupant protection in side im­
pacts.
How the head-protection airbags work
Applies to vehicles: with head-protection airbags
When fully inflated, the airbags reduce the risk
of head or chest injury in a side collision.
Fig. 203 Head-protection airbag in inflated condition
In certain types of side collision, the head-protec­
tion airbag is triggered on the impact side of the
vehicle ¢ Fig. 203. Further airbag systems may
also be triggered, depending on the circumstan­
ces.
When the system is triggered, the airbag fills
with a propellant gas and covers the entire area
in front of the side windows, including the door
pillars. In this way the system is able to protect
both the front and the rear occupants on the side
of the vehicle where the impact occurs. The head­
protection airbag inflates to soften the impact if

system
an occupant strikes parts of the interior or ob­
jects outside the vehicle with their head. By re­
ducing the head impact and restraining uncon­
trolled movement of the head, the airbag also
reduces the forces acting on the neck.
The front airbags, side airbags and head-protec­
tion airbags may be triggered together in certain
types of accident.
In order to provide the desired extra protection in
an accident, the airbags have to inflate extremely
rapidly (within fractions of a second). The airbag
releases a fine dust when it inflates. This is quite
normal and does not mean there is a fire in the
vehicle.
Important safety notes on the head­
protection airbags
Applies to vehicles: with head-protection airbags
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 ac­
cident.
A WARNING
- It is important to ensure that the area
around the openings for the head-protec­
tion airbags remains unobstructed at all
times, so that the airbags can inflate prop­
erly if needed.
- The built-in coat hooks should only be used
for lightweight clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
When using the coat hooks, do not hang the
clothes on coat hangers.
- The space between the passengers and the
head-protection airbags must never be oc­
cupied by children, other passengers or
pets. Passengers should never lean out or
put a hand or arm out of the window while
the vehicle is in motion.
- Do not move the sun visors out to cover the
side windows if there is anything attached
to them (such as pens or a remote control
for the garage door). These objects could
cause injury if the head-protection airbag is
triggered.
216 -
The sensors for the airbags are located in
the doors. You must therefore not make any
modifications to the doors or door trim (e.g.
retrofitting loudspeakers), as this could im­
pair the function of the side airbags. Any
damage to the doors could lead to faults in
the system. Repairs or any other work on
the doors must therefore always be carried
out by a qualified workshop.
- If unsuitable accessories are installed near
the head-protection airbag, the protection
afforded by the airbag can be seriously im­
paired 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 260.
- Any work involving the head-protection air­
bags, or removal and installation of the air­
bag components for other repairs (such as
repairs to the roof liner), must always be
performed by a qualified workshop. Other­
wise the airbag system may fail to work
properly.

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

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.

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

ent filling pump or seek professional assis­
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
fuel canister, you must use the special fun­
nel stowed in the Luggage compartment

systems
Catalytic converter
Applies to vehicles with petrol engine: The vehi­
cle must only be used with unleaded petrol; oth­
erwise the catalytic converter will be irreparably
damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­
ing. This allows unburnt fuel to enter the exhaust
system, which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to vehicles with diesel engine: The die­
sel particulate filter can filter out almost all soot
particles contained in the exhaust gas. In normal
driving conditions the filter is self-cleaning.
Should the self-cleaning function of the filter not
be able to operate, e.g. when the vehicle is con­
tinuously used only for short trips, the filter be-

obstructed with soot and the symbol Cl
for the diesel particulate filter lights up
¢page 15.
A WARNING
The exhaust system is very hot when the vehi­
cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission control system (cata­
lytic converter or diesel particulate filter),
do not park the vehicle where the exhaust
can come into contact with flammable ma­
terials under the car (e.g. on grass or at the
forest edge) -risk of fire!
- Do not apply any undersea[ agents in the
area around the exhaust system -risk of
fire!
