must always sit in an upright position,
must not lean against or place any part
of their body too close to the area where
the airbags are located .
- Occupants who are unbelted, out of posi­
tion or too close to the airbag can be se­ riously injured by an airbag as it unfolds
with great force in the blink of an eye
~ page 158.
A WARNING
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 install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer .
A WARNING
Objects between you and the airbag will
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
or by being pushed into you as the airbag
inflates.
- Never hold things in your hands or on
your lap when the vehicle is in use.
- Never transport items on or in the area
of the front passenger seat. Objects
could move into the area of the front air­
bags during braking or other sudden ma­
neuver and become dangerous projec-
Airbag system 167
tiles that can cause serious personal in­
jury if the airbags inflate.
- Never place or attach accessories or oth­
er objects (such as cupholders, tele­ phone brackets, large, heavy or bulky ob­
jects) on the doors, over or near the area marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those areas and yourself. These
objects could cause injury in a crash, es­
pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can also
move into the area of the side airbag or
the front airbag during braking or in a
sudden maneuver. Objects near the air­ bags can become projectiles and cause
injury, particularly when the seat is re­
clined.
A WARNING
The fine dust created when airbags deploy
can cause breathing problems for people
with a history of asthma or other breath­ ing conditions.
- To reduce the risk of breathing problems,
those with asthma or other respiratory
conditions should get fresh air right
away by getting out of the vehicle or
opening windows or doors.
- If you are in a collision in which airbags
deploy, wash your hands and face with mild soap and water before eating.
- Be careful not to get the dust into your
eyes, or into any cuts or scratches .
- If the residue should get into your eyes,
flush them with water. •

Child Safety
Important things to
know
Introduction
The rear seat is generally the safest place in a
collision.
The physical principles of what happens when
your veh icle is in a crash app ly also to chi ldren
~ page 150, What happens to occupants not
wearing safety belts?.
But unlike adults and
teenagers, their muscles and bones are not
fu lly developed. In many respects children are
at greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully deve l­
oped, they require restraint systems especial­
ly designed for their size, weight, and body
structure. Many countries and all states of the
United States and provinces of Canada have
laws requiring the use of approved child re­
straint systems for infants and small ch ildren.
In a fronta l crash at a speed of 20 -35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant w ill be more than 20 t imes the
weight of the child. This means the weight of
the child would suddenly be more than 260 pounds (120 kg). Under these conditions,
only an appropriate ch ild restraint properly
used can reduce the risk of ser ious injury.
Child restraints, like adult safety belts, must
be used properly to be effective. Used improp­
erly, they can increase the risk of serious in­
jury in an accident.
Consult the child safety seat manufacturer's instructions in order to be sure the seat is
right for your ch ild's size ~
page 181, Impor­
tant safety instructions for using child safety
seats.
Please be sure to read and heed all of
the important information and WARNINGS
about child safety, Advanced A irbags, and the
installation of child restraints in this chapter .
There is a lot you need to know about the Ad­
vanced Airbags in your vehicle and how they
work when infants and children in child re- straints are on the front passenger seat
. Be­
cause of the large amount of important infor­
mation, we cannot repeat it all here . We urge
you to read the detailed information in th is
owner's manual about airbags and the Ad­
vanced Airbag System in your vehicle and the
very important information about transport­
ing children on the front passenger seat.
Please be sure to heed the WARNINGS -they
are extremely important for your safety and
the safety of your passengers, especially in­
fants and small children.
A WARNING
-Accident statistics have shown that chil­
dren are generally safer in the rear seat
area than in the front seating position.
Always restrain any child age 12 and un­
der in the rear.
- All vehicle occupants and especially chil­
dren must be restrained properly when­
ever riding in a vehicle. An unrestrained
or improperly restrained chi ld could be
injured by str iking the i nterior or by be­
ing ejected from the vehicle during a
sudden maneuver or impact. An unre­
strained or improperly restrained chi ld is
also at greater risk of injury or death
through contact with an inflating airbag.
- A suitable chi ld restraint properly instal ­
led and used at one of the rear seating positions provides the highest degree of
protection for infants and small children
in most accident situations.
A WARNING ,_
Children on the front seat of any car even
with Advanced Airbags can be ser iously in­
jured or even killed when an airbag in­
flates. A child in a rearward-facing child
safety seat installed on the front passen­
ger seat will be seriously injured and can
be killed if the front airbag inflates.
- 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, or door.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) rein­
forces driver safety. It reduces the risk of slip ­
ping and improves driving stability. ESC de­
tects critical s ituations such as the vehicle
Intelligent technology 197
oversteering and understeering or the whee ls
spinning . The vehicle is stabilized by applying
the brakes or reducing eng ine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL), dy­
namic steering*, hill descent assist and selec­
tive wheel torque control.
Anti-lock braking system (ABS)
ABS prevents the whee ls from locking up
when braking . The vehicle can still be steered
even during hard braking. App ly steady pres­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations . You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels beg in to sp in and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hill s.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the othe r whee ls .
T his function is available up to about 78 mph
(125 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au­
tomatically when conditions have returned to
normal.

Fa u lts in th e brake sy stem
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circuits may have failed~.&. .
Low brak e flu id level
Malfunct ions can occur in the brake system if
the brake fl uid leve l is too low . T he b rake fluid
l eve l is monito red electronically .
Brake booster
The brake booster increases the pressure that
you generate w ith the brake pedal.
It only op­
e rates while the eng ine is running or with the
i gnit ion sw itched on (hybr id dr ive*) ~.&, .
Brake lining wear statu s
Brake lining wear may be checked by visual in ­
spection of the condition of the brake pads
through the openings in the whee l. If neces­
sa ry, the wheel may be removed for this in­
spection
~ page 2 74, Changing a wheel.
.&_ WARNING
=
- You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range . Do not ride
the brakes or hold the pedal down too long or too often . This could cause the
brakes to get hot and dimin ish b raking
efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the b rakes to
overheat, premat ure wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa­
ter , driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums . Carefully apply brakes
Int ellig ent technolog y 201
for a test. Brakes will dry and ice coat­
ings w ill be cleaned off after a few care­
ful brake applicat ions.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
f low to the front brakes is not obst ruct­
ed. Otherw ise the brake system could
overhea t reducing the effectiveness of
the entire brake system .
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopping distance . Avoid driving
the vehicle and have it towed to the near­
est a uthori zed Audi dea ler or qualified
workshop.
- Never let the vehicle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
examp le when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .

Driving with your
quattro ®
With all-wheel drive, all four wheels are driv ­
en .
General information
With all-wheel dr ive, power is distributed to
all four wheels. This happens automatically
depending on your dr iving style and the road
conditions at the time . See also ¢
page 197.
A center different ial distr ibutes the dr iv ing
power var iably to the front and rear axle.
It
works together with selective wheel torque
control, which activates when driving through
curves
¢ page 198.
The all-wheel drive concept is des igned for
high engine power. Your veh icle is exception ­
ally powerfu l and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precaut ions¢ &.
Winter tires
When driving in the winter, yo ur vehicle with
all -wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing: these tires must be mounted o n
all four
wheels .
See also¢ page 263, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also app lies to veh icles
with all-wheel drive¢
page 264, Snow
chains.
Replacing wheels/tires
Vehicles with all -wheel drive must always
have tires of the same s ize. A lso avoid tires
with different tread depths. For deta ils see
page
o page 2 59, New tires and replacing
tires and wheels.
A WARNING
-Always adjust your dr iv ing to road and traf-
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Altho ugh the all-wheel drive is very ef­
fective, always remember that braking
capacity is limited by tire traction. You
should therefore not d rive 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 begin to slide on top of the water
(aquaplaning). If this should occur, you

Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
• Always use lead-free gasoline¢ page 228,
Fuel supply.
• Never run the tank down all the way to
empty .
• Never put too much motor oil in your en-
gine ¢
page 238, Adding engine oil~-
., Never try to push- or tow -start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the life of the cata lytic conve rt­
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r operate the vehicle in
areas where the hot exhaust 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
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating could
overheat and cause a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 238.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned f uel could a lso get into the exhaust system and this co
uld cause
the cata lytic converter to overheat .
- Do not turn off the ignition while the ve ­
hicle is moving.
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained properly
and in accordance w it h the service rec­
ommendat ions in your Warranty &
M ain tenance book let.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em iss ion contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam ­
aged.
T his is espe cially true for ve hicles with low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles .

208 Driving and environment
would go unheeded. Extended idling also
produces heat, which could result in over­ heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
• Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ability to hold its value, it also affects
fuel
consumption.
Check your oil each time you fill your tank.
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain mileage has been driven .
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly
assess oil consumption .
This also applies to fuel consumption and en­
gine output .
{Q) Note
-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and
other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips.
• Try to avoid driving short distances with a
cold engine.
The engine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effectively.
Just after starting, a cold engine in a mid-size
car only achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a mile , fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 miles (4 km),
the engine is at its proper operating tempera­
ture and fuel economy has reached a normal level. So you can see that you should avoid
short trips whenever possible .
T he
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer .

mat ion of harmfu l deposits, sometimes called
"sludge ", that ove r time can lead to expensive
repairs .
At the time of pr int ing , engine o ils available in
the U .S . and Canada that meet the exacting
specifi cations of Audi oi l standard VW 502 00
a re synthetic engine oils. This does not mean,
however, that every syn thetic engine oil will
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the format ion of harmful de ­
posits use only oi l with the fo llowing specifi­
cations printed on the oil container :
Audi oil standard VW 502 00
O il container labe ls may carry the specif ica ­
tion s ingly or in comb inat ion with other des ig­
nations and oil qua lity standards .
Viscosity
Engine oi ls are graded according to their vis­
cosity. The proper viscosity grade oil for your
engine depends on cl imactic or seasonal con­
d itions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem ­
pe ratu re ranges for normal driving conditions .
However, if eng ine o il viscos ity grade SA E
SW40 is not avai lab le, you can also use viscos­
ity grade SAE SW -30 or SAE OW-40 as long as
it meets Audi o il quality standard VW 502 00
specif ications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an ext ra quart (
li te r) of oil that exp ress ly con forms to the
VW 502 00 spec ification, in case you have to
top
off the oil while on the road.
Only if the ba r of the o il level indica tor is near
" Mi n" - and no oil that express ly conforms to
Audi o il standard VW 502 00 specifications is
available - may you top
off w ith a high quality
engine oil, preferably synthetic-based, that
meets ACEA A3 or API SM spec ificat ions, but
even then, on ly in viscosity grades SAE
SW-40, SAE SW-30, or SAE OW-40 . Howeve r,
during the entire time between o il change in­
te rva ls , never top
off with more than a total
of 0 .5 qt/liter engine oil t hat does not con­
f orm to Audi oil specification VW 502 00 .

Changing the engine oil
T he eng ine o il and o il fil ter m ust be changed
accord ing to the mileage (k ilometers) and
time intervals specified in your ve hicle's War ­
ranty
& Maintenance booklet . Do not exceed
these interva ls - harmful deposits from old
engine oil can reduce eng ine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter­
vals is so very important because the lubricat­
ing propert ies of oil decrease gradually d uring
normal veh icle use. If you are not sure when
you have your oil changed, ask your author ­
ized Audi Se rv ice Adv isor.
Under some circumstances the engine oil
shou ld even be changed more frequent ly.
Change oil more often if you drive most ly
sho rt distances, operate the ve hicle in dusty
areas o r most ly unde r stop-and-go traff ic con­
ditions, o r when you use your vehi cle where
temperatu res s tay be low freezing point for
l ong periods .
