visibility conditions. For example, fog cannot be detected by the light sensors.
So always switch on the headlights 1§.D under these weather conditions and
when driving in the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists . Always turn on
the headlights so that you can see ahead
and so that others can see your car from
the back.
- Please observe legal regulations when
using the light ing systems descr ibed .
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic.
@ Tips
- The light sensor* for automatic head­ light range control* is located in the rear
view mirror mount. You should therefore not apply any stickers to the windshield
in this area in order to prevent malfunc­
tions or failures.
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display ¢
page 21.
-You will hear a warning tone if you open
the driver door when the exterior lights
are switched on .
- In cool or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after
switching them on. This does not affect
the service life of the lighting .
Clear vision 45
Emergency flasher
The emergency flasher makes other motorists
aware that you or your vehicle are in an emer­
gency situation .
Fig. 40 Ce nt er co nsol e: em erge ncy flash er sw itc h
.,. Press the switch &..¢ fig. 40 to turn the
emergency flashers on or off.
When the emergency flasher is on, all four
turn signals blink at the same time . The turn
signal indicator lights
B DI in the instru­
ment cluster, as well as the light in the emer­
gency flasher switch &.. blink likewise. The
emergency flashers also work when the igni­
tion is turned off.
The emergency flashers will turn on automati­
cally if you are in an accident where the airbag has deployed.
@ Tips
You should turn on the emergency flashers
when:
- you a re the last vehicle standing in a traf­
fic jam so that any other vehicles coming
can see you, or when
- your vehicle has broken down or you are
in an emergency situation, or when
- your vehicle is being towed by a tow
truck or if you are towing another vehicle
behind you.

.&_ WARNING
-The ra in sensor is only des igned to assist
and support the drive r.
It remains entire­
ly the dr iver's respons ibility to monitor
o utside wea ther conditions and to man­
ually activate the wipers as soon as rain
or drizzle reduces visibility through the
w indshield.
- The w indshie ld m ust not be treated with
water -repe llent materials. They can in­
c rease glare under poor visibi lity condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. I n addi­
tion, they can cause the windshield wip­
ers to chatte r.
- Properly functioning windshie ld w iper
blades are required for a clear view and
safe dr iv ing ¢

(D Note
-In the case of frost, check whether the
windsh ield wiper b lades a re frozen to
t h e windshie ld. Switching on the wind­
s h ield wipers can damage the wiper
blades!
- Prior to using a car wash, the win dsh ield
wipe r system must be switched off (lever
i n position @). This helps to prevent un ­
i ntent ional sw itch ing on and damage to
the windshie ld w iper sys tem .
- Do no t use the wipe rs to cle ar a frosted
window. Using the wipers as a conven­
i ent ice sc raper will destroy t he wiper
b lades .

Warm and cold Four-zone automatic
climate control
Description
Applies to vehicles: with four-zone automat ic climate co n­
tro l
The climate control system warms, cools and
adds humidity to the a ir in the veh icle inter io r.
It is the most effect ive when the windows and
sunroof* are closed.
If the temperature inside
the parked vehicle becomes very warm, open­ ing the window briefly will speed up the cool­
ing process.
I n all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensation from the cooling system can
drip and form a puddle of water under the ve­
hicle. This is normal and does not mean there
is a leak.
Pollutant filt er
The po llutant filter removes pollutants such
as dust and pollen from the air.
The air pollutants filter must be changed at
the intervals spec ified in your Wa rranty
&
Maintenance book let, so that the air condi ­
tioner can properly work.
I f you d rive your vehicle in an area with h igh
air po llution, the fi lter may need to be
changed more frequent ly than specified in
your Audi Warranty
& Maintenance booklet. If
in doubt, ask your authorized Audi Service Ad·
visor for advice.
Key coded setting s
The clima te control sett ings are a utomat ica lly
stored and assigned to the remote contro l key
that is in use .
Warm and c old 69
A WARNING
-
Reduced visibi lity is dangerous and can
cause acc idents .
- For safe driving it is very important that
all windows be free of ice, snow and con­
densat ion.
- Comp letely fam il iarize yourse lf with the
proper use and funct ion of the heat ing
a nd ventilation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer system in freez ing weathe r unt il you
have warmed the windshie ld first, using
the heating and ventilation system. The
washer sol ution may freeze on the wind­
shie ld and red uce visibi lity.
CJ) Note
- If you s uspect that the air conditioner
has been damaged, switch the system
off to avoid furt her damage and have it
inspected by a qualified dea lership .
- Repairs to the Audi air conditioner re­
quire specia l technical know ledge and
special tools. Contact an authorized Audi
dealer fo r ass istance.
@ For the sake of the envi ronment
By reducing the amount of f uel you use,
you also red uce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lo ts ( in front of the
w indshield) free from ice, snow and de­
bris in order to maintain the proper func­
tion of the climate control system.
- The energy ma nagement system may
switch the seat heating* or rear window defroster off temporar ily. These systems
are available again as soon as the energy
balance has been restored .
- Air escapes through vents under the rear window. When plac ing items of cloth ing
on the luggage compartment cover, en­
sure that the openings are not covered.

What impairs driving safety?
Safe driving is directly related to the condi­
tion of the vehicle, the driver as well as the
driver 's ability to concentrate on the road
without being distracted.
The driver is respons ible for the safety of the
veh icle and all of its occupants.
If your ability
to drive is impai red, safety r isks for everybody
in the vehicle increase and you also become a
hazard to everyone else on the road ¢
A.
Therefore:
.. Do not let yourself be distracted by passen­
gers or by using a cellular telephone.
.. NEVER drive when your driving ability is im­
paired (by medications, alcohol, drugs, etc.).
.. Observe all traffic laws, rules of the road
and speed limits and plain common sense .
.. ALWAYS adjust your speed to road, traff ic
and weather conditions .
.,. Take frequent breaks on long trips. Do not
drive for more than two hours at a stretch.
.. Do NOT drive when you are t ired, under
pressure or when you are stressed.
A WARNING
Impaired driving safety increases the risk
of serious personal injury and death when­
ever a vehicle is being used.
Driving Safely 121
Proper occupant
seating positions
Proper seating position for the driver
The proper driver seating position is impor­
tant for safe, relaxed driving .
Fig. 146 Correct seat ing pos it ion
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the driver's seat to the
follow ing position:
.. Adjust the driver's seat so that you can easi ­
ly push the pedals all the way to the floor
wh ile keeping your knee(s) slightly bent
¢.&_ .
.. Adjust the angle of the seatback so that it is
in an upr ight position so that your back
comes in full contact w ith it when you drive.
.. Adjust the steering wheel so that th ere is a
distance of at least 10 inches (25 cm) be­
tween the steering wheel and yo ur breast
bone
Q fig. 146. If not possible, see your au ­
thorized Audi dealership about adaptive
equipment .
.. Adjust the steering wheel so that the steer­
ing wheel and airbag cover points at your
chest and not at your face.
.,. Grasp the top of the steer ing whee l with
your elbow(s) slightly bent.
.. For adjustable head restra ints: Adjust the
head restraint so the upper edge is as even
as possible with the top of your head. If that
is not possible, try to adjust the head re­
straint so that it is as close to this position
as poss ible. Move the head restraint so that
it is as close to the back of the head as pos-
sible . .,.

A WARNING ,~
To help prevent poisonous exhaust gas
from being drawn into the vehicle, always
keep the rear lid closed while driving .
- Never transport objects larger than
those fitting completely into the luggage
area because the rear lid cannot be fully
closed.
- If you absolutely must drive with the rear
lid open, observe the following notes to
reduce the risk of poisoning:
- Close all windows,
- Close the power roof*,
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­ dows, the power roof* and the rear lid are
securely closed and locked to reduce the
risk of injury when the vehicle is not being
used.
- After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open. A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle .
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
Gj) Tips
-Air circulation helps to reduce window fogging. Stale air escapes to the outside
through vents in the trim panel. Be sure
to keep these slots free and open .
-
Driving Safely 127
-The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. The tire pressure la­
bel is located on the driver's side B-pillar.
The tire pressure label lists the recom­
mended cold tire inflation pressures for
the vehicle at its maximum capacity
weight and the tires that were on your
vehicle at the time it was manufactured. For recommended tire pressures for nor­
mal load conditions, please see chapter
I:!) page 233.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie-downs to secure your cargo prop­
erly<>
page 126, Loading the luggage com­
partment.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item. Vehicle speed is the most
significant factor.
For example , in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10-lb (4.5 kg) object are about 20 times the
normal weight of the item. This means that
the weight of the item would suddenly be about 200 lbs. (90 kg) . You can imagine the
injuries that a 200 lbs . (90 kg) item flying
freely through the passenger compartment
could cause in a collision like this.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
-Always use suitable mounting straps and properly secure items to the tie-downs in

144 Airbag system
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature.
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
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only supplemental protection .
- Airbag work most effectively when used
with properly worn safety belts.
- Therefore, always wear your safety belts
and make sure that everybody in your ve­
hicle is properly restrained .
- Always hold the steering wheel with both
hands on the outside of the steering
wheel rim at the 9:00 o'clock and 3:00
o'clock positions to help reduce the risk
of personal injury if the driver's airbag in­
flates.
- Never hold the steering wheel at the 12
o'clock position or with your hands any­
where inside the steering wheel or on the
steering wheel hub. Holding the steering
wheel the wrong way increases the risk of severe injury to the arms, hands, and
head if the driver airbag deploys.
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
and/or by being pushed into you as the air­
bag inflates.
-Always make sure nothing is in the front
airbag deployment zone that could be
struck by the airbag when it inflates.
- Objects in the zone of a deploying airbag
can become projectiles when the airbag
deploys and cause serious personal in­
Jury.
- Never hold things in your hands or on
your lap when the vehicle is in use .
-
-Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the
doors; never attach then to the doors or
the windshield; never place them over or
near or attach them to the area marked
.,AIRBAG" on the steering wheel, instru­
ment panel or the seat backrests; never place them between these areas and you
or any other person in the vehicle.
- Never attach objects to the windshield
above the passenger front airbag, such
as accessory GPS navigation units or mu­
sic players. Such objects could cause seri­
ous injury in a collision, especially when
the airbags inflate.
- Never recline the front passenger seat to
transport objects. Items can also move
into the deployment area of the side air­
bags or the front airbag during breaking
or in a sudden maneuver. Objects near
the airbags can fly dangerously through
the passenger compartment and cause
injury, particularly when the seat is re­
clined and the airbags inflate.
A WARNING
A person on the front passenger seat, es­
pecially infants and small children, will re­
ceive serious injuries and can even be kil­
led by being too close to the airbag when
it inflates.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the front passenger airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee
that deployment under these special
conditions is impossible in all conceiva­
ble situations that may happen during
the useful life of your vehicle.
- The Advanced Airbag System can deploy
in accordance with the ,,low risk" option
for 3- and 6-year-old children under the

U.S. Federal Standard if a child with elec­
trical capac itance greater than the com­
bined capacitance of a typical one-year
old infant restra ined in one of the for­
ward fac ing or rearward-fac ing ch ild
seats w ith which your vehicle was certi­
fied is on the front passenger seat and
the other conditions for airbag deploy­ ment are met.
- Acc ident statist ics have shown that chil­
dren are generally safer in the rea r seat
area than in the front seating posit ion .
- For their own safety, all children, espe­
c ially 12 years and younger, sho uld al­
ways ride in the back p roperly rest rained
for their age an d size .
Advanced front airbag system
Your veh icle is equipped w ith a front Advanced
Airbag System in comp liance with Un ited
States Federal Motor Vehicle Safety Standard 208 as applicable at the time your vehicle was
manufactured.
The front Advanced Airbag System supple­ ments the safety belts to provide add it iona l
protection for the driver's and front passeng­
e r's heads and upper bodies in frontal crashes.
The airbags inflate only in frontal impacts
when the vehicle dece le rat io n is high enough.
The front Advanced A irbag System for the
fro nt seat occupants is not a substitute for
your safety belts . Rather, it is part of the over­
all occupant rest raint system in your ve hicle.
A lways remember that the airbag system can
only help to pro tect you, if you are s itting up ­
righ t, wearing yo ur sa fety belt and wearing it
properly. This is why you and yo ur passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your veh icle
h as been certified to meet the " low r isk" re­
q uir ements for 3 and 6 year-o ld children on
the passenger s ide and very small adu lts on
the dr iver side. The low risk deployment crite­
ria are intended to he lp reduce the risk of i n­
j ury through interaction with the front airbag
A irbag system 145
that can occur, for examp le, by being too
close to the steering wheel and instr ument
panel when the airbag inflates .
In add ition, the system has been cert ified to
comply with the "s uppression" requirements
of the Safety Standard, to turn off the front
airbag for in fants 12 months o ld and younger
who are rest rained on the front passenger
seat in child restraints that are listed in the
Standa rd
c> page 167, Child restraints and
Advanced front airbag system .
"Suppression" requires the front a irbag on the
passenger side to be turned off if:
- a child up to abo ut one year of age is re­
strained on the front passenger seat in one
of the rear-fac ing or forward -facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad ­
vanced Airbag System in your ve hicle was
cert ified . Fo r a listing of the chi ld restraints

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 131, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenag ers, their muscles and bones are not
fu lly developed. In many respects children are
at greater risk of serious injury in crashes than
adu lts.
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 children .
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,
on ly an appropriate chi ld restraint properly
used can reduce the risk of ser ious injury .
Child restra ints, 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 chi ld's size ~
page 169 , Impor­
tant safety instructions for using child safety
seats.
Please be sure to read and heed all of
the important information and WARNINGS
about ch ild 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-
Child Sa fet y 165
straints are on the front passenger seat . Be­
cause of the large amount of important infor­
mation, we cannot repeat it a ll here . We urge
you to read the detailed information in this 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 chi ldren .
.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 ikin g the interior or by be­
ing ejected from the vehicle during a
sudden maneuver or impact. An un re ­
strained or improper ly 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 a irbag in­
flates. A child in a rearward-facing child
safety seat installed on the front passen­
ger seat will be ser iously injured and can
be killed if the front airbag inflates .
- The inflating airbag will h it 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.

Engine 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
qu ires little attention .
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of specially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with anticorros ion addi­
tives (50% for USA models; 60% for Canadian models) . This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's cooling system from
corrosion and scaling.
It also raises the boil ­
ing point of the coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi ­
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 ° F ( - 40 °C) Canada.
I f you must add coo lant, use a mixture of wa­
ter and coolant addit ive. Mixing the coolant
additive with distilled water is recommended.

your vehicle is sufficient to meet the cli ­
mate conditions. This is especia lly impor­
tant if you live in a region where the win­
ter is extremely co ld. If necessary, in­
crease the proportion of coolant additive
to 60% .
- When adding coolant additive to your
cooling system, remember :
- We recommend using only coolant ad­
ditive G12++ or G13 (check the label)
for your vehicle . This coolant additive is
avai lable at authorized Audi dealers .
Other types of antifreeze can signifi­
cantly reduce corrosion protection. The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Veh icle
Limited Warranty.
