Airbag system

— the two side airbags located in the sides of the
front backrests
— the airbag warning light in the instrument clus-
ter.
The airbag system is monitored electronically to
make certain that it is functioning properly at all
times. Each time you turn on the ignition, the air-
bag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety
belts and can help to reduce the risk of injury to
the driver's and front passenger's upper torso on
the side of the vehicle that is struck in a side col-
lision. The airbag deploys in side impacts and on-
ly when the vehicle acceleration registered by the
control unit is high enough. If this rate is below
the reference value programmed into the control
unit, the side airbags will not be triggered, even
though the car may be badly damaged as a result
of the collision. It is not possible to define an air-
bag triggering range that will cover every possi-
ble angle of impact, since the circumstances will
vary considerably between one collision and an-
other. Important factors include, for example,
the nature (hard or soft) of the impacting object,
the angle of impact, vehicle speed, etc.
= page 208, Important safety instructions on
the side airbag system.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas-
senger in position in the event of a side collision
so that the side airbags can provide protection.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall occu-
pant restraint system in your vehicle. Always re-
member that the side airbag system can only
help to protect you if you are wearing your safety
belt and wearing it properly. This is another rea-
son why you should always wear your safety
belts, not just because the law requires you to do
so > page 182, General notes.
It is important to remember that while the sup-
plemental side airbag system is designed to re-
duce the likelihood of serious injuries, other inju-
ries, for example, swelling, bruising, friction
burns and minor abrasions can also be associated
with deployed side airbags. Remember too, side
airbags will deploy only once and only in certain
kinds of accidents - your safety belts are always
there to offer protection.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an indication
of over-sensitive or failed airbag activation. In
some collisions, both front and side airbags may
inflate. Remember too, that airbags will deploy
only once and only in certain kinds of collisions -
your safety belts are always there to offer protec-
tion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed.
The
side airbag system will not deploy:
— when the ignition is switched off
— in side collisions when the acceleration meas-
ured by the sensor is too low
—in front-end collisions
—in rear-end collisions
—in rollovers.
In some types of accidents the front airbags and
side airbags may be triggered together.

Z\ WARNING
— Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position > page 208.
— If the airbag indicator light > page 18
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup-
posed to, or will not inflate when it should.

Child safety


— Never install a rearward facing child safety
seat on the front passenger seat if the PAS-
SENGER AIR BAG OFF 3%; light does not
turn on and stay on. Have the system in-
spected immediately by an authorized Audi
dealer or authorized Audi Service Facility.


ZA\ WARNING
— Forward-facing child seats installed on the
front passenger seat may interfere with the
deployment of the airbag and cause serious
personal injury to the child.
— If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety and
well-being require the following special pre-
cautions to be taken:
— Always make sure that the forward-facing
seat has been designed and certified by its
manufacturer for use on a front passenger
seat with a front and side airbag.
— Always carefully follow the manufacturer's
instructions provided with the child seat or
infant carrier.
— Never put the forward-facing child re-
straint up against or very near the instru-
ment panel.
— Always move the front passenger seat to
the highest position in the up and down
adjustment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as far away from the
airbag as possible, before installing the
forward-facing child restraint.
— Always make sure that the safety belt up-
per anchorage is behind the child restraint
and not next to or in front of the child re-
straint so that the safety belt will be prop-
erly positioned.
— Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
— Never place objects on the seat (such as a
laptop, CD player, electronic games device,
power inverter or seat heater for child
seats). These may influence the electrical

capacitance measured by the capacitive
passenger detection system and can also
fly around in an accident and cause serious
personal injury.
— Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat-
er for child seats) on the front passenger
seat if the device is connected to the 12-
volt socket or the cigarette lighter socket.
— Ifa seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys-
tem on this seat.
— Make sure that there are no wet objects
(such as a wet towel) and no water or oth-
er liquids on the front passenger seat
cushion.
— Always make sure that the PASSENGER
AIR BAG OFF #; light comes on and stays
on all the time whenever the ignition is
switched on.
— Never install a forward-facing child safety
seat on the front passenger seat if the
PASSENGER AIR BAG OFF %; light does
not turn on and stay on. Have the system
inspected immediately by an authorized
Audi dealer or authorized Audi Service Fa-
cility.
— Always buckle the child seat firmly in place
even if a child is not sitting in it. A loose
child seat can fly around during a sudden
stop or in a collision.
— Always read and heed all WARNINGS
whenever using a child restraint in a vehi-
cle > page 182, Safety belts, > page 189,
Airbag system and > page 210, Important
information.


G) Tips
Always replace child restraints that were in-
stalled in a vehicle during a crash. Damage to
a child restraint that is not visible could cause
it to fail in another collision situation.

to prevent the child safety seat from moving
=> page 219.
» Push the child safety seat down with your full
weight to get the safety belt really tight so that
the seat cannot move forward and sideways
more than 1 in (2.5 cm).
Infants up to about one year (20 lbs or 9 kg) are
best protected in special infant carriers and child
safety seats designed for their age group. Many
experts believe that infants and small children
should ride only in special restraints in which the
child faces the back of the vehicle. These infant
seats support the baby's back, neck and head ina
crash > fig. 163.

ZA\ WARNING
Not using a child safety seat, using the wrong
child safety seat or improperly installing a
child restraint increases the risk of serious
personal injury and death in a crash.
— Never install a rear-facing child restraint in
the forward-facing direction. Such restraints
are designed for the special needs of infants
and
very small children and cannot protect
them properly if the seat is forward-facing.

Py i3
Safety belts for the front passenger can be
locked with the convertible locking retractor to
properly secure child safety seats.
The safety belt emergency locking retractor for
the front passenger’s seat safety belt have a con-
vertible locking retractor for child restraints. The
safety belt must be locked so that belt webbing
cannot unreel. The retractor can be activated to
lock the safety belt and prevent the safety belt
webbing from loosening up during normal driv-
ing. A child safety seat can only be properly in-
stalled when the safety belt is locked so that the
child and child safety seat will stay in place.
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, a
child should always ride in the seat properly re-
strained for its age and size.

ZA\ WARNING
Improperly installed child safety seats in-
crease the risk of serious personal injury and
death in a collision.
— Always make sure that the safety belt retrac-
tor is locked when installing a child safety
seat. An unlocked safety belt retractor can-
not hold the child safety seat in place during
normal driving or in a crash.
— Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or ina collision.
— If the backrest is not securely latched, the
child and the child restraint will be thrown
forward together with the backrest and will
strike parts of the vehicle interior. The child
can be seriously injured or killed.
— The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof.
— Forward-facing child safety seats or infant
carriers installed on the front passenger's
seat may interfere with the deployment of
the airbag and cause serious injury to the
child.

Checking and Filling

The correct fuel type for your vehicle can be
found on a label located on the inside of the fuel
filler door. For additional information on fuel, see
=> page 223.
For the tank capacity in your vehicle, refer to the
Technical Data > page 285.
If the central locking system malfunctions, there
is a fuel filler door emergency release
=> page 226.


Z\ WARNING
Improper fueling procedures and improper
handling of fuel can lead to explosions, fires,
severe burns, and other injuries.
— Do not smoke. Keep away from open flames.
— The ignition must be switched off when re-
fueling.
— Mobile devices, radio devices, and other ra-
dio equipment should always be switched
off when refueling. Electromagnetic rays
could cause sparks and start a fire.
— If you do not insert the fuel pump nozzle all
the way into the filler tube, then fuel can
leak out. Spilled fuel can ignite and start a
fire.
— Never get into the vehicle when refueling. If
there is an exceptional situation where you
must enter the vehicle, close the door and
touch a metal surface before touching the
fuel pump nozzle again. This will reduce the
risk of electrostatic discharge that can cause
flying sparks. Sparks can start a fire when
refueling.

cur while refueling and the fuel vapors
could ignite.
— When using fuel containers made of met-
al, the fuel pump nozzle must always re-
main in contact with the container to re-
duce the risk of static charge.
— Insert the fuel pump nozzle as far as pos-
sible into the filler opening while refuel-
ing.
— Follow the applicable legal regulations in
the country where you are driving when
using, storing and transporting fuel con-
tainers.
— Make sure that the fuel container meets
the industry standards, for example ANSI
or ASTM F852-86.



Z\ WARNING
Transporting fuel containers inside the vehicle
is not recommended. Fuel could leak out of
the container and ignite, especially during an
accident. This can cause explosions, fires, and
injuries.
— If you must transport fuel in a fuel contain-
er, note the following:
— Always place the fuel container on the
ground before filling. Never fill the fuel
container with fuel while it is inside or on
the vehicle. Electrostatic discharge can oc-

C) Note
— Remove fuel that has overflowed onto any
vehicle
components immediately to reduce
the risk of damage to the vehicle.
— Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re-
sults from that can cause engine misfires.
Uncombusted fuel may enter the exhaust
system and increase the risk of damage to
the catalytic converter.
@) For the sake of the environment
Do not overfill the fuel tank, or fuel could leak
out when the vehicle is warming up.
@) Tips
— If adverse weather conditions cause the fuel
filler door to freeze shut, press on the cen-
ter of the filler door with the heel of your
hand and then try opening it again.
— The fuel filler door on your vehicle does not
lock if you lock the vehicle from the inside
using the central locking switch.
G) Tips
— Your vehicle is equipped with a misfueling
guard. It allows the vehicle to be fueled only
with the correct fuel pump nozzle.
—Aworn or damaged nozzle or a nozzle that
is too small may not be able to open the
