Securing child safety
seats
Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas­
senger can be locked with the convertible locking
retractor to properly secure child safety seats .
The safety belts emergency locking retractors for
the rear seats safety belts and for the front pas­
senger's seat safety belt have a convertible lock­
ing retractor for child restraints. The safety belt
must be locked so that belt webbing cannot un­
reel. The retractor can be activated to lock the
safety belt and prevent the safety belt webbing
from loosening up during normal driving. A child
safety seat can only be properly installed when
144
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, all
children, especially those 12 years and younger,
should always ride in the back seat properly re­
strained for their age and size.
A 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 re­
tractor is locked when installing a child
safety seat. An unlocked safety belt retrac­
tor cannot 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 in a collision.
- Always make sure that the rear seat back­
rest to which the center rear safety belt is
attached is securely latched whenever the
rear center safety belt is being used to se­
cure a child restraint.
-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 .
- Never install rear-facing child safety seats
or infant carriers on the front passenger
seat. A child will be seriously injured and
can be killed when the passenger airbag in­
flates.
- 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.
-Always install rear-facing child safety seats
or infant carriers on the rear seat.

f ires and injuries.
- If you must transport fuel in a fue l contain­
er, p lease note the following:
- Always place a fue l co nta iner on the
ground befo re fil ling . Neve r fill the fuel
contai ne r with fuel whi le i t is in o r o n the
vehicle. Elect rostatic charge can oc cu r
while refueling and the fuel vapo rs could
ignite.
- Fo r fuel con tai ners made o f me tal, the
fuel p ump nozzle must a lways maintai n
contact with the container to reduce the
risk of stat ic charge.
- Insert the fuel pump nozz le as far as pos­
sible into the f iller opening wh ile refuel­
ing .
- Fo llow lega l req uirements when using,
stor ing and transporting fuel conta iners .

large cloth when opening.
- Do not remove the engine cover under any circumstances. This increases the risk of
burns.
- If tests need to be performed with the en­
gine running, there is additional danger due
to moving components (such as the ribbed belt, alternator and radiator fan) and from
the high-voltage ignition system.
- Do not under any circumstances give gas in­
advertently (for example, by hand from the
engine compartment) if the vehicle is sta­
tionary but the engine is running and a gear
is engaged. Otherwise, the vehicle will start
to move immediately and this could result
in an accident.
- Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke .
- Never work near open flames.
- Always have a working fire extinguisher
nearby.
- All work on the battery or electrical system
in your vehicle can result in injuries, chemi­
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed:
- Ignition cable
- Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb .
T his applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
Sheet metal and bu lb holders can have sharp
edges that can cause serious cuts, pa rts must be
correctly taken apart and then properly put back
together to help prevent breakage o f parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Aud i dea ler rep lace any bulbs fo r
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
