exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system inspected immediately by your Audi dealer .
A 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
precautions 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 install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions require the top tether strap to be used.
- Never put the forward-facing child re­
straint up against or very near the instru­
ment panel.
-Always set the safety belt upper anchor­
age to the adjustment position that per­
mits proper installation in accordance
with the child restraint manufacturer's in­
structions.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing the
child restraint. The backrest must be ad ­
justed to an upright position .
- 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 de­
vice, power inverter or seat heater for
child seats) . These may influence the elec­
trical capacitance measured by the capaci­
tive 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.
- If a 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.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immediate­ ly install the forward-facing child seat in a
rear seating position and have the airbag
system inspected by your authorized Audi
dealer.
- 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.

weighs more than 20 lbs. (9 kg).
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 we ight

The airbag on the passenger side makes the front
seat a potent ially dangerous place for a child to
ride . The front seat is not the safest place for a
ch ild in a forward-fac ing ch ild safety seat .
It is a
very dangerous place for an infant or a large r
ch ild in a rea rward-faci ng seat .
& WARNING
Not using a child safe ty se at, us ing t he wrong
chi ld safety seat or improperly insta lling a
chi ld restraint increases the risk of serious

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 child 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 a irbag will hit the child safety
seat or infant carrier with great force and
will smash the ch ild safety seat and chi ld
against the bac krest, center arm rest, door
or roo f.
- Always install rear-facing child safety seats
on the rear seat.
- If you must install a rearward fac ing ch ild
safety seat on the front passenger seat be­
cause of exceptiona l circumstances and the
PASSENGE R AIR B AG OFF light does not
come on and stay on, immediate ly install
the rear-fac ing ch ild safety seat in a rear
seating pos ition and have the airbag system
inspected by your Audi dealer.
- The rear side of the child safety seat should
be pos it ioned as close as poss ible to the
backrest on the vehicle seat.
- For adjustable head restraints: adjust or re­
move the rear seat head restraint if it is d if­
ficult to install the child seat with the head restra int in place ¢
page 60. Install the
head restraint again immediately once the
child seat is removed. Driving w ithout head
restra ints or w ith head restraints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically.

Gasoline additives
A ma jor concern among many auto manufactur­
ers is carbon deposit build-up ca used by the type
of gasoline yo u use.
A lthough gasoline gr ades d iffer from one manu ­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Dete r­
gent Gasoline, please go to the official website (www.toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
g ine of peak performance.

Checking and Filling
CJ) Note
-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives with the AdBlue and do not dilute it
with water.
- Only use refill bottles that are approved for your vehicle. Using other systems can cause Ad Blue to leak.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the Ad Blue tank. Do not start
the engine under any circumstances if the
wrong fuel is filled in the tank . There is a
risk of damaging the fuel tank system and
the engine . See an authorized Audi dealer or
authorized Audi Service Facility for assis­
tance.
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as possible with a
damp cloth and plenty of cold water. If the
Ad Blue has already crystallized, use warm
water and a sponge. AdBlue residue that is
not removed will crystallize and can damage
the affected surface .
- Do not store the refill bottle in the vehicle.
If it leaks, the escaping Ad Blue could dam­
age the vehicle interior .
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa ­
ter .
(D Tips
-You can obtain refill bottles from an author­
ized Audi dealer or authorized Audi Service
Facility .
- Follow the Ad Blue manufacturer's instruc­
tions for use and storage .
- A permitted refill bottle contains approxi­
mately 1.9 liters of AdBlue .
- Ad Blue can freeze at very low temperatures.
If this happens, the system will not detect
that the Ad Blue was refilled and it will con­
tinue to inform you of the low AdBlue level.
The message turns off as soon as the tank
thaws out again.

Engine compartment
Working in the engine compartment
Special care is required if you are working in the
engine compartment
For work in the engine compartment such as
checking and filling fluids, there is a risk of in­
jury, scalding, accidents, and burns. For this
reason, follow all the following listed warnings
and general safety precautions. The engine
compartment is a dangerous area.
¢ .&. .
.8, WARNING
To reduce the risk of injuries, complete the
following steps before opening the hood:
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
- Place the selector lever in the P position.
- Let the engine cool down.
- Never open the hood when you see that
steam or coolant drips from the engine
compartment- there is a danger of burns!
Wait until no steam or coolant flows out.
- Keep children away from the engine com­
partment.
- Never spill fluids on a hot engine. These flu­
ids (such as the freeze protection contained in the coolant) can catch fire.
- Avoid short circuits in the electrical system,
especially the battery.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm . The
cooling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
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 ~

Checking and Filling
-To reduce the risk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at least the total amount of oil in your engine .
- Engine oil is poisonous. Keep it well out of
the reach of children .
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
CD Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
-Before changing your oil, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used engine oil properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station.
Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sealed and generally re­
quires little attention.
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed. The coolant consists of a mixture of
244
specially conditioned water and the manufactur­
er's glycol-based coolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­ els; 60% for Canadian models). This mixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing system from corrosion and scaling. It also
raises the boiling point of the coolant.
Do not reduce the concentration of the coolant in
the summer by adding plain water.
The propor­
tion of coolant additive must be at least 50%
but not more than 60%
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine cooling system.
For year-round driving, antifreeze is added at the
factory for temperatures down to:
--31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
~ page 236.
CD Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­ ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold.
If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember:
- We recommend using only coolant addi­
tive Gl2++ or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The resulting
