0 :r Child safety
Toddlers and children who are older than one
year up to about 4 years old and weigh more than
20 lbs (9 kg) up to 40 lbs. (18 kg) must always be
properly restrained in a child safety seat certified
for their size and weight

The airbag on the passenger side makes the front
seat a potentially dangerous place for a child to
ride. The front seat is not the safest place for a
child in a forward -facing child safety seat. It is a
very dangerous place for an infant or a larger
child in a rearward-facing seat .
_&. WARNING
Not using a child safety seat, us ing the wrong
child safety seat or improperly instal ling a
chi ld restraint increases the risk of serious
personal injury and death in a collision or oth ­
er emergency situation.
- Children on the front seat of any car, even
with Advanced Airbags, can be seriously in­
jured or even killed when an airbag inflates.
A child in a rearward-facing ch ild safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System .
- The inflating airbag will hit the child safety
seat or infant carr ier with great force and
will smash the child safety seat and child
against the backrest, center arm rest, door
or roof.
-Al ways install rear-fa cing child safety seats
on the rear seat .
- If you must insta ll a rearward facing child
safety seat on the front passenger seat be­
cause of excep tional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rea r-facing child safety seat in a rear
seating position and have the a irbag system
inspected by your Audi dealer .
- The rear side of the ch ild safety seat shou ld
be positioned as close as possible to the
backrest on the veh icle seat. Adjust the rear
seat head restraint if it is difficult to install
the child seat w ith the head restraint in

Securing child 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 saf ety belt webbing
from loosening up during normal driving. A child
safety seat can only be properly installed when
the safety belt is locked so that the child and
child safety seat will stay in place .

- Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the speci­
fied criteria in this chapter .
- If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control

Gasoline additives
A pp lies to: ve hicles w ith gasoline engine
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use .
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
268
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
gine of peak performance.
([) Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle
Limited Warranty.
Refueling
· Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap .
If the power locking system should fail, you can
still open the flap manually -for detailed instruc­
tions see
~ page 2 70.
You can find the fuel tank capacity of your vehicle
in
~ page 334 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
~ page 267.
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and
polluting the environment while you refuel your
vehicle . In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
& WARNING
-Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc .,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/AS TM F8S2 -86).

Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
sions or serious injuries.
- Fuel ignites easily and can cause serious
burns and other injuries.
-
-If you do not switch the engine off when fu­
eling and/or do not insert the fuel nozzle
completely into the tank opening, fuel can
leak out or run over. Leaked fuel can ignite
and start a fire.
- Do not use the telephone while fueling. The
electromagnetic rays can cause sparks,
which can ignite fuel vapors and start a fire .
- Do not sit in your vehicle while fueling. If
you must make an exception and enter your
veh icle aga in while fueling, close the door
and touch metal to discharge static electric­
ity before touching the fuel nozzle. Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the
risk of an explosion.
- For your safety, carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the event of an accident.
- If you must make an exception and trans­
port a fuel container, note the following:
269

Checking and Filling
-Never fill the fuel container with fuel
while it is in or on the vehicle. Static elec­
tricity is discharged when filling which can
cause the fuel vapors to ignite and in­
creases the risk of an explosion .
- Always place a fuel container on the
ground before filling .
- Always hold the fuel nozzle completely in
the fuel container when filling .
- If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This
prevents static electricity from discharg­
ing.
- Never spill fuel in the vehicle or the lug­
gage compartment . Evaporated fuel is ex­
plosive and increases the risk of serious in­
jury or death.
- Follow legal requirements when using,
storing and transporting fuel containers.
- Make sure the fuel container conforms to
industry standards (ANSI/ASTM F852-86).
0 Note
- Remove spilled fuel from vehicle paint im­
mediately, because it can damage paint.
- 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 will 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, otherwise fuel
can leak out when the vehicle is warming up.
