Warm and cold Climate controls
Description
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 r eached a certain
temperature.
Condensation from the cooling system can
drip and form a puddle of water under the ve­hicle. This is normal and does not mean there
is a leak.
Pollut ant filter
The po llutant filte r removes pollutants s uch
as dust and pollen from the air.
The air pollutants filte r must be changed at
the intervals spec ified in you r Wa rra nty
&
Maintenance book let, so that the air condi­
tioner can properly work.
I f you drive you r vehicle in an area with h igh
ai r po llution , the fi lter may need to be
changed more freq uent ly than specified in
your Aud i Warranty
& Ma intenance booklet. If
i n doubt, ask your authorized Audi Service Ad­
visor for advice .
K ey coded settings
The climate con trol settings are a utomat ica lly
stored and assigned to the remote contro l key
that is in use .
& WARNING
Reduced visibility is dangero us and can
cause accidents . -
Warm and cold 75
- For safe driving it is very important that
all windows be free of ice, snow and con­
densat ion.
- Comp letely fam iliarize yourse lf with the
proper use and funct ion of the heat ing
and ve nti lation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the w indshield first, using
the heating and ventilation system . The
washer solution may free ze o n the wind­
shie ld and red uce visib ility.
(D Note
- If you suspect that the air conditioner has been damaged, switch the system
off to avoid furt her damage and have it
i n spected by a q ua lified dea lership.
- Repairs to the Audi air conditioner re­
quire specia l techni cal know ledge and
special tools. Contact an autho rized Aud i
dealer fo r ass istance.
@ For the sake of the environment
By reduci ng the amou nt of f uel you use,
you also red uce the amount of pollutan ts
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
br is in order to maintain the proper f unc ­
tion of the climate control system.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporar i Ly . 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.

88 Audi adapti ve cruise control and bra king gu ard
vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the v ideo camera, an acute col­
lis ion warn ing .
- For safety reasons, do not use adaptive
cruise co ntrol when driving on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing) . Using the system under
these cond it ions cou ld result in a co lli ­
sion .
- Swi tch adap tive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones . This prevents the vehicle from ac­
celerat ing to the set speed when in these
situations.
- The adapt ive cruise control system wi ll
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and d istance regulation .
- When approaching stationary objects such as stopped traff ic, adaptive cruise
co ntrol will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people, an­
imals, objects c rossing the road or on­
coming objects .
- The function of the radar senso rs can be
affected by reflective objects such as
guard rai ls , the entrance to a tunnel,
heavy rain or ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise contro l canno t slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function cannot br ing the vehicle to a
sudden or emergency stop under these condit ions.
- To prevent unintended operation, always switch ACC off when it is not being used. (D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That cou ld affect the adaptive
cruise control system and brak ing guard.
Have your authorized Aud i dea ler or au ­
thorized Audi Service Facility check their
funct ion .

- Always remember that the radar sensor
for the Audi braking guard works only
within defined detection and range limits
that may prevent the proper detection of
other vehicles .
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not
be promptly detected or may not be de­
tected at al l.
- Reflective surfaces includ ing crash barri­
ers or tunnel entrances may impair the

-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 vehi­ cles in your blind spot, only after your ve­
hicle 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 . Vehi­
cles in the adjacent lane may not be de­
tected 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.

Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries.
Wear ing safety be lts imprope rly can cause se ­
rio us inj ury or death. Safety be lts can on ly
wo rk when they are correct ly positioned on
the body. Improper seating positions reduce
the effect iveness of safety belts and will even
increase the r isk of injury and death by mov­
ing the safety belt to cr itical areas of the
body. Imprope r seat ing pos it ions also in­
crease the risk of serio us in jury and death
when an air bag deploys and str ikes a n occu­
pant who is not in the correct seating posi­
tion . A d river is responsib le for the sa fety of
all vehicle occupants and especially for chi l­

Safety belt preten­
sioners
How safety belt pretensioners work
In front, side and rear -end collisions above a
particular severity and in a rollover , safety
belts are tensioned automatically.
Reversible safety belt tensioners
T he safety belts on the fro nt sea ts ar e e qui p­
ped with powe r reversib le tensioners . The fo l­
lowing functions a re ava ila bl e when the driv­
er's/front passenger's safety belts are fas­
tened :
- Automatic tens ioners : at the star t of a drive,
the safety belts automat ica lly adjust to the
passe nger afte r a certain time period or ve ­
hicle speed. To switch the automatic ten­
sioners off, select the following in the MMI:

Taking up the slack helps to reduce 1111>

forward occupant movement during a colli­
sion.
A WARNING
- It is possible for the pretensioners to de­
ploy incorrectly.
- The pyrotechnic system can only provide
protection for one collision . If the pyro­
technic pretensioners deploy, the preten­
sioning system must be replaced.
(D Tips
The pyrotechnic safety belt pretensioners
can only deploy once.
- The safety belt pretensioners do not de­
ploy in minor frontal and side collisions,
in rear-end collisions, in rollovers and in
collisions involving very little impact
force .
- A fine dust is released when the pyro­
technic safety belt pretensioners deploy.
This is normal and is not caused by a fire
i n the veh icle.
- The relevant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped . A
qualified dea lership is familiar with
these regulations and will be pleased to
pass on the information 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 authorized Audi dealer perform this
service for you.
Service and disposal of safety belt
pretension er
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
Safety belts 141
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 be lt system.
- Safety belt systems including safety belt
pretensioners cannot be repaired. Spe­
cial procedures are required for removal,

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.
.&_ 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 cup
holders 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
moi5tened with plain water. Solvent5 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.
- 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.
- For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­
nic 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.
® For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate Material - special handling may apply, see

have your dealer perform this service for
you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi, lower ing the vehicle, changing the stiffness of
the suspension, including the springs, suspen­ sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
un it . Some suspension changes can, for exam­
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not dep loy if the
changes had not been made. Other kinds of
changes may reduce the force Levels meas­
ured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is poss ible that an airbag
will not deploy at a seating position where the
safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious personal injury in a crash.
Airbag system 157
-Never install suspension components
that do not have the same performance
characteristics as the components origi­
nally installed on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
-
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that they are not obstructed.
Knee airbags
Description of knee airbags
The knee airbag system con provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 149 Driver 's airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
¢ fig . 149, the airbag for the passenger is at
about the same height in the instrument pan­
el underneath the glove compartment.
The knee airbag offers additional protection
to the driver's and passenger's knees and up ­
per and Lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also deploy in frontal col lisions when the de­
ployment threshold stored in the control unit .,,.

& WARNING
-Never let the vehicle roll to a stop with
the engine shut
off.
- If the brake booster is not working, for
example 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.
Servotronic ® -
advanced power
steering system
-
The power steering systems use the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic ® power steering
system senses the road speed and e lectroni­
cally adjusts power ass istance to provide com­
fortable and safe steering response exactly matched to the veh icle speed.
Power steering wi ll not work if the engine is
off. As a resu lt, the steering whee l wi ll be hard
to turn.
The power steering fluid level is checked dur­ ing the scheduled maintenance services.
(D Note
I f there is an electronic malfunct ion, ser­
votronic
will sti ll function like a conven­
tional power steering system, providing a
constant steering support force that is no
longer proportionate to the vehicle speed.
This is most noticeable when turning the steer ing whee l at low speeds (for examp le
when parking), -more effo rt will be re­
qui red than usual.
- Be awa re of the different than usual
steering response and adjust your stee r­
i ng fo rce accord ingly.
- Have the p roblem checked and set right
by an Aud i dealer as soon as possib le .
Int ellig ent technolog y 191
(D Tips
-When the engine is running, never ho ld
the steering wheel turned all the way to
the right or to the left for longer than 15
seconds. The power steering pump will
overheat the hydrau lic fluid if you keep
holding the stee ring wheel turned all the
way. This is likely to damage the power
steering system.
- If the powe r stee ring system should fa il
entire ly, o r if the e ngine is not run ning
(for example, wh ile be ing towed), you
w ill still be able to stee r the veh icle.
However,
considerably more effor t will
be required to do so .
- If the power stee ring system sho uld
have a lea k, or is not functioning proper ­
ly, contact your authorized A udi dealer
immediately.
- The power steering system req uires a
specially formu lated hydra ulic fluid. The
