Warm and cold Climate controls
Description
Th e climate control sy stem 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* a re 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 f unctions 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.
Pollutant filter
The po llutant filte r removes po llutants s uch
as dust and pollen from the air.
The air pollutants filte r must be changed at
t he intervals spec ified in you r Wa rra nty
&
Main tenance book let, so tha t the air condi
tioner can properly work.

108 Audi side assist
-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 veh icles 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.

A WARNING
- It is possible for the pretensioners to de
ploy incorrectly.
- The pyrotechnic system can only provide
protection for one co llision. 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 invo lving very litt le impact
force .
- A fine dust is released when the pyro
techn ic safety belt pretens ioners deploy.
This is normal and is not caused by a fire i n the veh icle.
- The relevant safety requirements must
be obse rved when the vehicle or compo
nents of the system are scrapped . A
qualified dea le rship is familiar with
these regulations and w ill be pleased to
pass on the informat ion to you.
- Be sure to observe all safety, environ
mental and other regulations if the vehi
cle or indiv id ual parts of the system, par
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your a uthorized Audi dea ler perform this
serv ice for you .
Service and disposal of safety belt
pretension er
The safety belt pretensione rs are parts of the
safety bel ts on your Audi . Installing, remov
ing, servicing or repa iring of belt pretens ion
e rs can damage the safety be lt system and
prevent it from working correct ly in a colli
sion.
There are some important th ings you have to
know to make sure that the effect iveness of the system wi
ll not be impaired and that dis
carded components do not cause injury or pol
l ute the environment .
A WARNING ,.__
Improper care, servic ing 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 act i
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
pretens ioners cannot be repaired. Spe
cial procedures are required for removal,
installation and disposa l of th is system.
- For any wo rk on the safety belt system,
we strongly recommend that you see
your author ized Audi dealer or qualified
technician who has an Audi approved re
pair manua l, training and special equip
ment necessary.

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, lowering the vehicle, chang ing the stiffness of
the suspension, including the spring s, suspen
sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and sent to the electronic control
unit . 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 deploy 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 possible 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.
- 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 e lectronic 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 .

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 sys
tem senses the road speed and electron ically
ad ju sts powe r ass istance to provide comfor ta-
Int ellig ent technolog y 203
ble and safe steering response exactly match
ed to th e vehicle speed .
Power steer ing will not work if the engine is
off . As a result, the steering wheel will be h ard
to tu rn.
T he powe r stee ring fluid level is checked d ur
i ng t he sched uled maintena nce services.
(D Note
If there is an e lectronic malfunction, ser
votronic
will s till fu nction like a conven
tiona l powe r steering system, providing a
constant steering s upport force tha t is no
l onge r proportionate to the vehicle speed.
This is most noticeab le when t urni ng the
steering wheel at low speeds (for example
when parking), -more effort w ill be re
quired than usual.
- Be aware of the different than usual steering response and adjust your steer
ing force accordingly.
- Have the problem checked and set right by an Audi dealer as soon as possible.
(D Tips
-When the engine is running, never hold
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 hydraulic fluid if yo u keep
holding the stee ring wheel turned all the
way. This is likely to damage the power
steering sys tem.
- If the powe r stee ring system should fa il
entire ly, o r if t he engine is not runn ing
(for example, wh ile be ing towed), you
w ill still be able to steer the veh icle .
However,
considerably more effort will
be required to do so .
- If the powe r steering system sho uld
have a leak, or is not functioning proper
ly, contact your author ized Audi dealer
immediately.
- The power steering system req uires a
specially formu lated hydraulic fluid. The
power steering fluid reservoir is located
in the engine compartment
