@ Tips
- The light sensor* for headlight control is
located in the rear view m irror mount.
You should therefore not apply any st ick­
ers to the windsh ield in this area in order
to prevent malfunctions or failures.
- Some exterior lighting functions can be
adjusted

- When you remove your key from the igni­
tion while the vehicle's lights are turned
on, a buzzer sounds as long as the driv­
er's door is open .
- In cool or damp weather, the ins ide of
the headlights, turn signals and tail lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clea r shor tly after
switching them on. This does not affect
the service life of the lighting.
- In the even t of a light sensor malfunc­
tion, the driver is no tified in the instru­

76 Warm and cold
Warm and cold Climate controls
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior.
It is the most effect ive when the windows and
sunroof are closed . If there is a build-up of
heat inside the vehicle, ventilation can help to
speed up the cooling 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.
Condensat ion 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 filter
The pollutant filter removes pollutants s uch
as dust and pollen from the air.
The air pollutants filter must be changed at
the intervals spec ified in you r Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work.
If you drive your vehicle in an area with h igh
a ir po llution, the fi lter may need to be
changed more frequent ly than specified in
your Aud i Wa rranty
& Ma intenance booklet. If
in doubt, ask your authorized Audi Service Ad ­
visor for advice .
Key coded settings
The climate control settings are automat ically
stored and assigned to the remote control key
that is in use.
A WARNING
Reduced visibility is dangerous and can
cause accidents.
-
- For safe driving it is very important that
all windows be free of ice, snow and con­
densation.
- Comp letely familiarize yourself with the
proper use and function of the heating
and ventilation system and especially how to defog and defrost the windows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the windshield first, using
the heating and ventilation system. The
washer solution may freeze on the wind­ shie ld and reduce visib ility.
(D Note
- If you suspect that the air conditioner
has been damaged, switch the system
off to avoid further damage and have it
inspected by a qualified dealership.
- Repairs to the Audi air conditioner re­
quire special technical know ledge and
special tools. Contact an authorized Aud i
dea ler fo r assistance.
@ For the sake of the environment
By reducing the amount of fuel you use,
you also reduce the amount of pollutants
emitted into the air.
(D Tips
-Keep the air intake s lots (in fro nt of the
w indshield) free from ice, snow and de ­
bris in order to maintain the proper func­
tion of the climate control system.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporarily . These systems
are available again as soon as the energy
balance has been restored.
- Air escapes through vents under the rear
window. When placing items of clothing
on the luggage compartment cover, en­
sure that the openings are not covered.

100 Audi adaptive cruise control and braking guard
confirmed by the video camera, an acute
collision warning.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing). Using the system under
these conditions could result in a colli­
sion.
- Switch adaptive cruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construc tion
zones. This prevents the vehicle from ac­
celerating to the set speed when in these
situations.
- Th e adaptive cruise control system w ill
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation.
- When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adaptive cr uise control system and
braking guard do not react to people, an­
ima ls, objects crossing the road or on­
coming objects .
- The function of the radar sensor can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a vehicle so closely that you cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
ano ther vehicle too closely . Always re­
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch ACC off when it is not being used.
{[) Note
The sensor can be d isp laced by impacts or
damage to the bumper, whee l housing and
underbody . That could affect the adaptive cruise control system and b
raking guard.
Have your authorized Audi dea ler or au­
thorized Audi Service Facility check their
function.

The adaptive cru ise control system only reacts
to objects that are moving or that the system
has a lready detected as moving. For example,
if a vehi cle@ , which has already been detect­
ed by the adaptive cruise control, turns or
changes lanes and another stationary vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.

-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der all conditions- danger of accident!
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed
of at least 19 mph (30 km/h).
- In certain situations, the system may not
function or its function may be limited.
For example:
- if vehicles are approaching or being left
behind very quickly. The display may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow or heavy mist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface .
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the system .
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
(D Tips
- If the window glass in the driver's door
or front passenger's door has been tint­
ed, the display in the exterior mirror may be misinterpreted.

Safety belts 143
Improperly worn safety belts
I ncorrectly positioned safety belts can cause
severe injuries .
Wearing safety belts improperly can cause se­
rious injury or death. Safety belts can only
work when they are correctly positioned on
the body . Improper seat ing pos itions reduce
the effectiveness of safety be lts and will even
i ncrease the risk of injury and death by mov­
ing the safety be lt to crit ica l areas o f the
body. Improper seating positions also in ­
crease the risk of serious injury and death
when an airbag dep loys and strikes an occu­
pant who is not in the correct seating posi­
tion. A driver is responsible for the safety of
all vehicle occupants and especially for ch il­
dren . Therefore:
.. Never permit anyone to assume an incorrect
sitt ing position in the vehicle while traveling
¢ &,. .
A WARNING
Improperly worn safety belts increase the
risk of serious persona l injury and death
whenever a ve hicle is being used.
- Always make s ure that all vehicle occu­
pa nts are co rrectly restrained and stay in
a co rrec t seating position whenever the
veh icle is being used .

Safety belt preten­
sioners
How safety belt pretensioners work
In front , side and rear -end collisions above a
particular severity, safety belts are tensioned automatically.
The safety belts are equipped with safety belt
pretensioners . The system is activated by sen­
sors in front, side and rear-end co llisions of
great seve rity . This tightens the belt and takes
u p belt slack¢.&.
in Service and disposal of Iii>

144 Safety belts
safety belt pretensianer on page 144. Taking
up the slack helps to reduce forward occupant
movement during a collision.
{[) Note
Never let the belt remain over a rear seat­
back that has been folded forward.
(D Tips
The safety belt pretensioner can only be activated once.
- In minor frontal and side collisions, in
rear-end collisions, in a rollover and in
accidents involving very little impact
force, the safety belt pretensioner are
not activated.
- In the case of a side crash, the safety
belt pretensioners will activate on the
driver's or front passenger's sides only,
depending on which side of the vehicle
the crash occurs .
- When the safety belt pretensioners are
activated, a fine dust is released. This is
normal and is not caused by a fire in the
vehicle.
- The relevant safety requirements must
be observed when the vehicle or compo ­
nents of the system are scrapped . An au­
thorized Audi dealer or qualified work­
shop is familiar with these regulations
and will be pleased to pass on the infor­
mation to you.
- Be sure to observe all safety, environ­
mental and other regulations if the vehi­
cle or individual parts of the system, par­
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your authori zed Audi dealer perform this
service for you .
Service and disposal of safety belt
pretensioner
The safety belt pretensioners are parts of the
safety belts on your Audi . Installing, remov­
ing, servicing or repairing of belt pretension­
ers can damage the safety belt system and prevent it from working correctly
in a colli­
sion.
There are some important things you have to
know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing a safety belt
pretensioner from activating when needed
or activating it unexpectedly :
- The belt pretensioner system can be acti ­
vated only once . If belt pretensioners
have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety belt system.
- Safety belt systems including safety belt
pretensioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposal of this system.
- For any work on the safety belt system,
we strongly recommend that you see
your authorized Audi dealer or qualified
technician who has an Audi approved re­
pair manual, training and special equip­
ment necessary.

A WARNING
Improper care, servicing and repair proce ­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way .
- Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft , dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body .
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi .
Airbag system 159
-Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer .
- The airbag system can be activated only
once . After an airbag has inflated , it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­ placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a
pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer - risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre ­
cautions must be followed.

(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
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 serv iced at regular inter-
vals .
By having your vehicle regularly serviced by an
author iz ed Audi dealer helps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab il ity to hold its value, it also affects
fu el
c onsump tion .
C hec k your oil each tim e you fill your t ank .
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 d rive yo ur vehicle about 3 ,000 miles
(5,000 kilometers) be fore you can properly
assess oi l consumption.
This a lso applies to fuel consumption and en­
g ine output .

Fewer short trips
Fuel consumption will always be rela tively
high on short trips .
.,. Try to avoid driving short distances with a
cold engine.
The engine and cata lytic converter have to
reach their opt imal

Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 mi les
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
