Child safety
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 safe ­
ty seat . An unlocked safety belt retractor
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.
- 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 rearward-facing child safety seats or infant carriers on the front passen­
ger 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 rearward-facing child safety
seats or infant carriers on the rear seat.
- Forward-facing child safe ty 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.
- It is safer to install a forward-facing child
safety seat on the rear seat.
- Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
being used~
page 150 . Special precautions
apply when installing a child safety seat on
the front passenger seat~
page 129, Child
restraints on the front seat -some impor­
tant things to know.

A WARNING
-
Always take special precautions if you must
install a forward or rearward-facing child re ­
straint on the front passenger's seat in excep­
tional situations:
- Whenever a forward or rearward -facing
child restraint is installed on the front pas­
senger seat, the
PASSENGER AIR BAG OFF
light must come on and stay on whenever
the ignition is switched on.
- If the PASSENGER AIR BAG OFF light does
not come on and stay on, perform the
checks described ~
page 138, Monitoring
the Advanced Airbag System.
- Take the child restraint off the front passen­
ger seat and install it properly at one of the
rear seat positions if the
PASSENGER AIR
BAG OFF
light does not stay on whenever
the ignition is switched on.
- Improper installation of child restraints can
reduce their effectiveness or even prevent
them from providing any protection.
- An improperly installed child restraint can
interfere with the airbag as it deploys and
seriously injure or even kill the child .
- Always carefully follow the manufacturer 's
instructions provided with the child safety
seat or carrier.
- Never place additional items on the seat
that can increase the total weight registered
by the weight-sensing mat and can cause in­
jury in a crash .
A WARNING
Forward-facing child restraints:
- Always make sure the forward-facing seat
has been designed and certified by its man ­
ufacturer for use on a front seat with a pas­
senger front and side airbag .
- Never put the forward-facing child restraint up , against or very near the instrument pan­
el.
-Always move the passenger seat into its
rearmost position in the seat's fore and aft
-

adjustment range, as far away from the air­
bag as possible before installing the for­
ward-facing child restraint. The backrest must be adjusted to an upright position .
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on .
A WARNING
Rearward-facing child restraints:
- 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 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 be especially careful if you must in­
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir­
cumstances.
- A tight tether strap on a rearward-facing
child restraint attached to the front passen­
ger seat can put too much pressure on the
weight-mat in the seat and register a heavi­ er weight in the Advanced Airbag System .
The heavier weight registered can make the
system work as though an adult were on the
seat and deploy the Advanced Airbag when
it must be suppressed causing serious or
even fatal injury to the child.
- 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, immediately in­
stall the rearward-facing child safety seat in
a rear seating position and have the airbag
system inspected by your authorized Audi
dealer.
Child safety
Activating the convertible locking retractor
Use the convertible locking retractor to secure a
child restraint .
Always heed the child safety seat manufacturer's
instruc tions when installing a child restrain t in
your vehicle . To activate the convertible locking
retractor:
.. Place the child restraint on a sea t, preferably on
the rear seat.
.. Slowly pull the belt
all the way out .
.. Route it around or through the child restraint
belt path
~ . & .
.. Push the child safety seat down with your full
weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for that
seating posit ion.
.. Guide the saf ety belt back into the retractor un­
til the belt lies flat and snug on the child safety
seat .
.. You should hear a "clicking" noise as the belt
winds back into the inertia reel. Test the con­
vertible locking retractor by pulling on the belt .
You should no longer be able to pull the belt
out of the retractor. The convertible locking re­
tractor is now activated .
.. Make sure that the red release button is facing
away from the child restraint so that it can be
unbuckled quickly.
.. Pull on the belt to make sure the safety belt is
properly tight and fastened so that the seat
cannot move forward or sideways more than
one inch (2 .5 cm) .
A WARNING
Using the wrong child restraint or an improp­
erly installed child restraint can cause serious
personal injury or death in a crash .
- Always make sure that the safety belt re­
tractor is locked when installing a child safe­
ty seat. An unlocked safety belt retractor
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 crash. ..,.

Winter tires
When driving in the w inter, your vehicle w ith all­
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be advisa­
ble to mount winter tires (or all-season tires) for
improved driveability and braking: these tires
must be mounted on
all four wheels. See also
c:> page 211, Winter tires .
Tire chains
Where tire chains are mandatory on certain
roads, th is normally also applies to vehicles with
all-wheel drive
c:> page 211, Snow chains.
Replacing wheels/tires
Vehicles w ith all-wheel drive must a lways have
tires of the same size . Also avoid tires with differ­
ent tread depths. For details see page
c:> page 203, New tires or wheels.
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road vehicle. It is there­
fore best to avoid rough tracks and uneven ter­
rain as much as possible . Also refer to
c:>page 177.
A WARNING
Always adjust your driving to road and traffic
conditions. Do not let the extra safety afford­
ed by all-wheel drive tempt you into tak ing
extra risks .
- Although the all-wheel drive is very effec­
tive, always remember that braking capac ity
is limited by tire traction. You should there­
fore not drive at excessive speeds on icy or
slippery road surfaces.
- On wet road surfaces, be careful not to drive
too fast because the front wheels could be­
gin to slide on top of the water (aquaplan­
ing). If this should occur, you will have no
warning from a sudden increase in engine speed as with a front-whee l drive vehicle .
Always drive at speeds which are suited to
the road conditions -risk of crash .
Smart Technology
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa ­
bility of electrical energy for starting the engine.
If a vehicle with a conventional energy system is
not driven for a long period of time, the battery
is d ischarged by idling current consumers (e.g .
immobilizer). In certain circumstances it can re­
su lt in there being insufficient energy available to
sta rt the eng ine .
Intelligent energy management in your vehicle
hand les the distribution of electrical energy .
Starting ability is markedly improved and the life
of the battery is extended.
Basically, energy management consists of
bat­
tery diagnosis , idling current management
and
dynamic energy management .
Battery diagnosis
Battery diagnosis continuously determines the
state of the battery . Sensors determine battery
voltage, battery current and battery tempera­
ture . T his determines the current state of charge
and the power of the battery.
Idling current management
Idling current management reduces energy con­
sumption while the vehicle is standing . With the
ignition switched off, it controls the energy sup­
ply to the various electrical components. Data
from battery d iagnosis is considered.
Depend ing on the battery's state of charge, indi­
vidual consumers are gradually turned off to pre­
vent excessive discha rge of the batte ry and thus
mainta in starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic energy
manageme nt distr ibutes the energy gene rated
accord ing to the needs of the individual compo­
nents.
It regu lates consumption, so that more
elect rical energy is not being used than is be ing
generated and ensures an optima l state of
charge for the battery. ..,.

Driving and th e environment
(D Tips
-Check the depth of the water before driving
through it.
- Do not stop the veh icle, drive in reverse or
switch the engine
off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to dr ive
through safely.
- Avoid driving through sa lt water because it
can cause corrosion.
Warming up and cooling down
By carefully warming up and cooling down your
veh icle, you can help ensure that it is not over­
stressed unnecessar ily du ring sporty dr iv ing.
When warming up, the vehicle is driven at a max­ imum engine speed of 6000 RPM in order to ra ise
the engine oil temperature to a m inimum of
140 °F (60 °C). T he tires also only reach their full
road holding capab ility once they have wa rmed
up.
The cooling fan can continue to run in your vehi­
cle after the eng ine is switched
off. However,
d riving the vehicle to cool it dow n is part icu larly
important. During sporty d riving, the engine and
brakes , the exhaust system, and the transmission
all become extremely hot. Before you park the
vehicle, you should drive it for a few mi les/kilo ­
meters at light load in the low rpm range to al­
low it to cool down.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in on
environmentally sound manner .
.. Always use lead -free gasoline c::> page 183,
Fuel supply.
.. Never ru n the tank down a ll the way to empty.
.. Neve r pu t too m uch motor oil in your engine
c::> page 191, 't:::?: Adding engine oil .
178
.. Never try to push -or tow-start your vehicle .
The catalytic converte r is an effi cient "clean-up"
device b uilt into the exha ust system of the veh i­
cle. The cata lytic conve rter burns many o f the
po llutants in the exhaust gas before they are re­
l eased into the atmosphere.
The exclusive use of unleaded fue l is c ritically im ­
po rtant for the life of the catalytic conver ter and
proper functioning of the engine .
A WARNING
-The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exhaust tail pipes once they
have become hot. Th is could resu lt in burns.
- Do not park or operate the vehicle in areas
where the hot exha ust system may come in
contact with dry grass, brush, fuel spill or
other material which can cause a fire.
- Do not apply additional undercoating or rustproof ing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or
heat shields. During dr iving, the substance
used for unde rcoat ing could overheat and
cau se a fire.
@ Note
- Be aware that just one tank fill ing with lead­
ed
fuel w ill al ready ser iously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
c::>poge 191.
-Do not drive until the fue l tank becomes
completely empty . T he engine cou ld m isfire .
Unburned fu el could also get into the ex­
haus t sys tem a nd this could cause the cata­
lyt ic converte r to overheat.
- Do not turn
off the ignition while the vehicle
is
moving.
- Do not continue to operate your veh icle un­
der these condi tions, as otherwise f uel can
re ach the cat aly tic converter. This could re ­
s u lt in ove rheat ing of the c onve rter, requ ir­
ing its replacement .

Care and cleaning
A WARNING
- Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourse lf
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect may be delayed due to moisture on the
brake rotors or ice in the winter . The brakes
must be dried first w ith a few careful brake
applications.
@ Note
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be fo lded in and out us ing the power folding
funct ion.
- To prevent pa int damage, do not wash the
vehicle in direct sunlight .
- To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­ moved.
@ For the sake of the environment
On ly wash the vehicle in facilities specially de­
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.

~ Insert the fuel nozzle from the gasol ine pump
into the fuel filler neck as far as it will go.
~ Select a medium refuelling rate so that the
nozzle switches off automat ica lly when the
tank is full.
Putting the fuel cap back on
~ After filling your tank, tw ist the f uel cap clock­
wise as far as it wi ll go.
~ Close the fuel filler flap.
Fuel and Refueling
To avoid fuel spilling or evaporating from the fuel
tank always close fue l cap proper ly and com­
pletely .
A WARNING
--
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
- Failure to shut the engine off while refuel­
ing and/or to insert the pump noz zle fully
into the fue l filler neck could cause fuel to
spray out of filler neck or to overflow . Fuel
spray and overflowing fuel can cause a fire.
- Never use a cellular telephone while refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire .
- Never get back into your vehicle while refu­
eling. If in exceptional circumstances you
must get back in your vehicle whi le refuel­
ing, make certain that you close the door
and touch metal to discharge static electric­
ity before touching the filler nozzle again.
Static electricity can cause sparks that can ignite fue l vapors re leased during refueling.
- Never smoke or have an open f lame any­
where in or near your vehicle when refueling
or filling a portable fue l conta iner .
- For your safety, we strongly recommend
that you do not travel with a portable f uel
container in your vehicle. The container, full
or empty may leak and cou ld cause a fire,
especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
ple ase observe the following:
- Never fill a portable fuel container while it
is anywhere in or on the veh icle (for exam­
ple, in the luggage compartment, or on
the trunk). Static e lectricity can build up
while filling and can ignite fuel vapors
causing a f ire.
- Always place a portab le fue l container on
the ground before filling .
185

Fuel and Refueling
-Always keep the fi ller nozzle completely
inside the portable container before and
during filling.
- If filling a portable container made of
metal, the filler nozzle must always be in
contact with the container. This will help
prevent static electricity from discharging
and cause a fire .
-Never sp ill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammab le.
-Always observe local and state/provincia l
laws regarding the use, storage and trans­
portat ion of fuel containers.
- Make certain the fuel container meets in­
dustry standards (ANSI/ ASTM F852 -86) .
(D Note
If any fuel has spilled onto the car, it should
be removed immediately to prevent damage
to the paint .
@ For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first time,
the tank is full. Do not try to add more fuel
because fuel may spill out . In addition, the
expansion space in the fuel tank will be filled·
causing the fuel to overflow when it becomes
warm and pollute the environment.
(j) Tips
- Running your engine while refuelling may
cause vapors to escape or even cause fuel to
sp il l out of the tank . This wo uld then shut
off the fuel nozzle before the tank is full.
- Do not refuel your veh icle with the ignition
turned on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling.
- The fuel filler flap of your vehicle is not
l ocked when you lock the vehicle from the
inside .
