Belt tensioners

Reversible
belt tensioners*
The following functions are available when seat
belts with reversible belt tensioners are buckled:
- The seat belts can be tensioned reversibly in
certain situations
^>page
120.
- The seat belts can be also be tensioned reversi­
bly in light collisions.
Pyrotechnic belt tensioners*
Seat belts with pyrotechnic belt tensioners are
tensioned automatically in severe collisions, de­
pending on the circumstances. This helps to re­
duce the forward motion of the occupants.

A,
WARNING
- False activation of the
belttensioner
is pos­

sible.

- Any work on the tensioner system or remov­
al and installation of system components
for other repairs must be performed by a
qualified workshop.
- The pyrotechnic system can only be activa­
ted once. If the pyrotechnic belt tensioners
have been activated at any time, the system
must be replaced.

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.
- 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 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.
© Note
All the other airbags in the car will remain
functional if the front passenger's airbag has
been deactivated.
Head-protection airbags
Description of head-protection airbags



Fig.
234 Location of head-protection airbags above the
doors (example)
The head-protection airbags are located above
the doors on the left and right sides of the
vehi­

cle.
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

•=>
A in Important safety notes on the head-pro­
tection airbags on page 287.
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
When fully inflated, the airbags reduce the risk
of head or chest injury in a side collision.

The head-protection airbag system is triggered in
certain types of side collision
^>Fig.
235. Further
airbag systems may also be triggered, depending
on the circumstances.
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. The head-protection airbag inflates to
soften the impact if an occupant strikes parts of
the interior or objects outside the vehicLe with
their head. By reducing the head impact and re­
straining uncontrolled movement of the head,
the airbag also reduces the forces acting on the
neck.
In order to provide the desired extra protection in
an accident, the airbags have to inflate extremely
rapidly (within fractions of
a
second).
Important safety notes on the 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
garage door
opener). These objects could cause injury if
the head-protection airbag is triggered.
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 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.
Sun blinds fitted on the rear doors 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 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
340.
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.

A WARNING

- If
you
have no alternative but to install a
rearward-facing child seat on the front pas­
senger's seat, the front passenger's airbag
must be deactivated beforehand. Potential­
ly fatal injuries to the child can result if the
front passenger's airbag is not deactivated

•=>
page 267
- If
you
have deactivated the front passeng­
er's airbag, reactivate it as soon as the child
seat is no longer needed so that the airbag
can continue to give the required protec­

tion.

- It is the driver's responsibility to ensure that
the key-operated switch is set to the correct

position.

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. Petrol
must be sulphur-free and must comply with the
EN 228 standard. You can fuel your vehicle with
fuels containing a maximum of 10%
ethanol

(E10). 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

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.

© CAUTION
- Do
NOT fuel
your vehicle with
high-ethanol

fuel blends (e.g. E50 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.
- 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 complying with
the EN 590 standard is recommended.
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
offer winter-grade diesel fuel during the cold

Emission controL
systems
Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded pet­

rol,
otherwise the catalytic converter will be ir­
reparably 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 diesel particulate filter can filter out almost
all soot particles contained in the exhaust gas. In
normal driving conditions the filter is self-clean­

ing.
Should the self-cleaning function of the filter
not be able to operate, e.g. when the vehicle is
continuously used only for short trips, the filter
becomes obstructed with soot and the indicator

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, do not
park the vehicle where the exhaust can
come into contact with flammable materials
under the car (e.g. on grass or at the forest
edge) - risk of fire!
- Do not apply any underseal agents in the
area around the exhaust system - risk of

fire!

Engine compartment
Working on components in the engine
compartment
Extra caution is necessary when working on com­
ponents in the engine compartment.
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment (e.g.
when checking and refilling fluids). Always ob­
serve the warnings listed below and follow all
normal safety precautions. The engine compart­
ment of any motor vehicle is a potentially haz­
ardous area
oA-

A WARNING
- Switch off the engine.
-Switch off the ignition.

-Applythe
parking brake.
- On vehicles with manual gearbox place the
gear lever in neutral, on vehicles with auto­
matic gearbox move the selector lever to
position P.
- To avoid the risk of being scalded, never
open the bonnet if
you
see steam or coolant
escaping from the engine compartment.
Wait until no steam or coolant can be seen
before opening the bonnet.
- Wait for the engine to cool down.
- Keep children away from engine compart­
ment.
- Never spill fluids on a hot engine. These
flu­

ids can cause a fire (e.g. radiator
anti­

freeze).
- Take care not to cause short circuits in the
electrical system.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off - risk of injury!
- Do not unscrew the cap on the expansion
tank when the engine is hot. The cooling
system is under pressure.
- Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.
295

Checking and topping up fluids
- Never remove the engine cover panel - risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive

belts,
alternator and radiator
fan,
etc., and
from the high-voltage ignition system.
- Never touch the radiator fan. The electric
additional fan is controlled by temperature
and can start running without warning.
- Applies to vehicles with automatic gearbox:
Never open the throttle inadvertently (for
instance by hand from the engine compart­
ment) if
a
gear is engaged while the vehicle
is stationary with the engine running. The
vehicle will otherwise start moving immedi­
ately and could cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
- Any work on the batteries and electrical sys­
tem in your vehicle entails a risk of injury
and chemical burns in addition to danger of
accident or fire.
For
this reason, you must
have the work carried out by
a
qualified
workshop.
© CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening. This
can otherwise cause serious malfunctions or
engine damage.
® For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any Leaks are detected at an
early stage. If
you
find spots of oil or other

fluids,
have your vehicle inspected in the
workshop.
