Audi adapt ive crui se c ontrol an d bra kin g guard 8 7
vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the video camera, an acute col­ lis ion warn ing.
- For safety reasons, do not use adaptive
cruise control 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 itions cou ld result in a co lli ­
sion .
- Switch adaptive 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
celerating to the set speed when in these
situations .
- The adapt ive cru ise 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 adapt ive cruise control system and
braking guard do not react to people, an­
ima ls, objects crossing the road o r on­
coming objects .
- The function of the radar sensors can be
affected by reflective objects such as
guard ra ils, the entra nce to a tunnel,
he avy rain or i ce.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise cont ro l c anno t slow or
brake the veh icle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
funct ion cannot bring the veh icle to a
sudden or emergency stop under these
condit ions .
- To prevent unintended operation, always
switch ACC off when it is not be ing 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 le r or a u­
thorized Audi Serv ice Facility check their
funct ion.

Applies to vehicles: with Audi adaptive cruise control
I
F ig. 90 Ex ample: dri vin g in to a curve
When dr iving into a curve c:> fig. 90 and out of
a cu rve, the ad aptive cruise con trol may react
to a vehicle in the next lane and apply the
brakes . You can override or prevent the brak­
i ng by pressing the accelerator pedal b riefly.
Stationary objects

Audi active Lane assist
Active Lane assist
Description
Applies to vehicles: with active lane assist
Active lane assist helps you keep your vehicle
in your lane.
Active lane assist detects lane marker lines
within the limits of the system using a camera in the windshield . If you are approaching a de­
tected lane marker line and it appears likely
that you w ill leave the lane, the system will
warn you by means of corrective steer ing . T he
driver can over ride the cor re ct ive steer ing at
any time. If the veh icle crosses a line, the d riv­
er is also warned by a light
vibration in the
steering whee l. The vibration warning must
be switched on in the MMI for this to happen.
Active lane ass ist is operable when the line
marking the lane is detected on at least one
side of the vehicle .
If the system is in active standby mode and
the turn signa l is activated before driving over
the lane marker line, the warning does not oc­
cur since the system allows for intentional lane changes .
The system is designed for driv ing on free­
ways and expanded highways and thus works
only at speeds of 40 mph (65 km/h) or more .
If the vehicle is also equipped with Audi adap­
tive cruise control*, the corrective steering
will be more specif ic in regard to the driving
situation . In addition to the lane marker lines,
the system can a lso take into acco unt other
objects such as guard rails. If they are detect­
ed i n close proximity to the veh icle, Audi a c­
tive lane ass ist helps prevent the vehi cle from
driving too close to them . The re is also pass­
ing assistance. The system does not provide
any corrective steering if it detects that you
are passing another vehicle.
A WARNING
- The system warns the driver that the ve­
hicle is leaving the lane us ing corrective
Audi acti ve lane a ssis t 95
steer ing. The driver is always responsible
for keeping the vehicle within the lane.
- The system can assist the driver in keep­
ing the vehicle in the lane, but it does
not steer by itself. A lways keep your
hands on the steering wheel.
- Corrective steering may not occur in cer­ tain sit uat ions, such as dur ing heavy
brak ing.
- The camera does not recognize all lane
marker lines. Corrective steer ing can only
take p lace on the side of the vehicle
where lane marker lines are detected .
- Other road structures or objects cou ld
possibly be identified un intent ionally as
lane ma rker lines. As a result, cor rect ive
steer ing may be unexpected or may not
oc cur .
- The camera view can be restricted, for
examp le by vehicles driving ahead o r by
r ai n, snow, heavy spray or light s hining
into the camera. This can result in a ctive
lane assist not detecting the lane marke r
lines or detect ing them inco rrectly .
- Unde r ce rtain condi tions such as ruts in
the road, a banked roadway or cross­
winds, the corrective stee ring alone may
not be enough to keep the vehicle in the
lane.
- For safety reasons, active lane ass ist
must not be used when there are poor
road and/or weather condit ions such as
slippery roads, fog, gravel, heavy rai n,
snow and the potent ial for hydroplaning .
Using act ive lane assist under thes e con­
ditions may increase the risk of a crash.

"' a, 0 0 " a,
Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
@ Vehicl es th at ar e approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still
somewhat far away. The fas ter a vehicle ap­
p roaches, the sooner the display in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr itical
for a lane change. All vehicles detec ted by
side assist are indicated by the time they en­
ter your "blind spot", at the latest.
Audi side assist 99
@ Veh icle s left behind
If you s low ly pass a vehi cle that s ide assist has
detected (the difference in speed between the
vehicle and you r vehicle is less than 9 mph or
15 km/h), the display in the exterio r mir ror
turns on as soon as the vehicle enters your blind spot.
T he disp lay will not t urn on if you quickly pass
a vehicle that side assist has detected (the dif­
ference in speed between the veh icle and your
vehicle is greater than 9 mph or 15 km/h).
Functi onal limitations
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the d isp lay in the exterior mirror may
turn on even though there is no veh icle locat­
ed in the area that is cr itical for a lane change.
For example:
- if the lanes are narrow or if your are dr iving
on the edge of your lane.
If this is the case,
the system may have detected the vehicle in
another lane that is
not adjacent to your
current lane .
- if you a re driving through a curve. Side assist
may react to a vehicle that is one lane ove r
from the adjacent lane.
- if side assist reacts to other objects (such as
high or d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are l imited .
Do not cover the radar sensors
c> fig. 10 7 with
stickers, depos its, bicycle wheels or other ob­
jects, because this will affect the funct ion. Do
not use s ide ass ist when towing a trailer. For
i nformation on cleaning, refer to
c> page 212 .
_&. WARNING
-Always pay attention to traffic and to t he
area a round your ve hicl e. S ide assist can­
not replace a driver's attention. T he driv­
er a lone is always responsible for lane
changes and similar driving mane uvers.

100 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.
@ 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.

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
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 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
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.
Airbag system 163
-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 deploy only once. After an airbag has been deployed, it must be replaced with new replacement
parts designed and approved especially
for your Audi model version. Replace­
ment of complete airbag systems or air­
bag components must be performed by
qualified workshops only . Make sure that
any airbag service action is entered in
your Audi Warranty
& Maintenance book­
let under
AIRBAG REPLACEMENT RE­
CORD.
- 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 technicians who have the ex­
perience, information and special tools
necessary to perform the work safely.
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.

chlorate. When the vehicle or parts of the

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-r im combinations not approved by Aud i,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion st ruts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and se nt to the electron ic control
un it. Some suspension changes can, for exam­
p le, increase the force levels meas ured 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 a irbag
from deploying when it should.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire -rim combina­
tions can change Advan ced A irbag per­
formance and increase the risk of serio us
personal in jury in a crash.
- Never install suspension components
that do not have the same performance character istics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinatio ns that
have not been approved by A udi.
Knee airbags
Description of knee airbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
F ig . 1 65 Driver's knee airbag
The driver knee airbag is in the ins trumen t
pane l underneath t he steering wheel
¢ fig. 165, the airbag for the passenger is at
about the same height in the instrument pan­
el underneat h the glove compartment.
T he knee airbag offe rs additional p rotection
to the driver 's and passenger's knees and up­
per and lower th igh areas and supplements
the protection provided by the safety belts.
If t he front airbags dep loy , the knee ai rbags
also dep loy in frontal coll isions when the de­
ployment threshold stored in the contro l unit
is met
¢ page 15 7, More important things to
know about front airbags.
In addition to their norma l safety function,
safety belts help keep the dr iver or front pas­
senger in position in a fronta l collision so that
the a irbags can provide supplemental protec­
t ion .
The airbag system is not a substit ute for your
safety belt. Rather, it is part of the overa ll oc­
cupant restra int system in your vehicle. Al­
ways remember that the a irbag system can
o nly help to protect you if you are weari ng
your safety belt and wea ring i t properly. This
is why you should always wear your safety
belt, not just beca use the law requi res you to
do so
