Audi adapt ive crui se c ontrol an d bra kin g guard 9 3
vehicles or obstacles that are not moving
can trigger a collision warning and if conÂ
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 Â
sion .
- Switch adaptive c ruise control off tempoÂ
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones . This prevents the vehicle from acÂ
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 , anÂ
ima ls, objects crossing the road o r onÂ
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,
heavy 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 reÂ
member that the automatic braking
funct ion cannot bring the veh icle to a
sudden or emergency stop under these
conditions .
- 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 a uÂ
thorized Audi Serv ice Facility check their
funct ion.

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 deÂ
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 rivÂ
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 .
The system is designed for driv ing on free Â
ways and expanded highways and thus works only at speeds of 40 mph (65 km/h) or more .
Applies to vehicles with side assist* : If you acÂ
tivate your turn s ignal when active lane assist
is ready and when activated side assist has
classified a lane change as crit ica l because of
vehicles traveling alongside you or comi ng
closer, there will be noticeable correct ive
steer ing just before you leave the lane . This is
done to try to keep your veh icle in the lane.
Applies to vehicles w ithout s ide ass ist*: when
the system is ready, it does not warn you if
you act ivate your turn signa l before driving
across a lane marker line . In this case, it asÂ
sume s that yo u are ch ang ing lanes intent ionÂ
a lly.
I f the vehicle is also equipped with Audi adapÂ
tive cruise cont ro l*, the co rrec tive steering
will be mo re specific in rega rd to the driving
situation. In addition to the lane marker lines,
the system can a lso take into account other
objects such as guard rails . If they are detectÂ
ed in close proximity to the veh ic le, Audi ac-
Audi acti ve lane a ssis t 10 1
tive lane assist he lps prevent the vehicle from
driving too close to them. There is a lso passÂ
ing ass istance . The system does not provide
any correct ive steering if it detects that you
are passing another vehicle.
A WARNING
- The system warns the drive r that the veÂ
hicle is leaving the lane using co rrect ive
s teer ing . The d river is always r esponsible
for keeping the vehicle withi n the lane.
- The system can assist the dr iver in keepÂ
i n g the vehicle in the lane, but it does
not steer by itself. A lway s keep yo ur
h a nds on the steering wheel.
- Cor rective s teer ing may not occur in cerÂ
tain sit uat ions, such as dur ing heavy
bra king.
- Th e camera does not recogni ze all lane
marker lines. Cor rective s teer ing ca n only
take p lace on the side of the vehi cle
where lane marke r lines are detected.
- Othe r road str uctures o r objects co uld
possibly be identified unintentiona lly as
lane ma rker lines . As a res ult, corrective
steering may be unexpected or may not
occ ur.
- The camera view can be restricted, for
examp le by vehicles driving ahead or by
ra in, snow, heavy spray or light shining
into the camera . Th is can result in act ive
lane assis t not detecti ng the lane marke r
lines or detect ing them inco rrectly.
- Unde r ce rtain conditions such as ruts in
the road, a banked roadway or crossÂ
winds, the co rrective stee ring alone may
not be enough to keep the vehicle in the
lane.
- For safety reasons, active lane ass ist
m ust not be u sed w hen the re a re poor
road and/or weat her condi tions such as
slippe ry roads, fog, grave l, heavy rain,
snow an d the potential for hydroplaning .
Using active lane assist under these conÂ
ditions may increase the risk of a crash.

AUDI
Fig. 114 Rear of t he ve hicle: positio n of t he se nsors
Side assist functions at speeds above approx iÂ
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 apÂ
p roaches, the sooner the display in the exteriÂ
or m irror will t urn on.
@ V ehicles 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 enÂ
ter your "blind spot", at the latest.
Audi side assist 105
© 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 exterior mirror
turns on as soon as the vehicle enters your blind spot.
The disp lay will not t urn on if you quickly pass
a vehicle that side assist has detected (the difÂ
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 situaÂ
tions, the d isp lay in the exterior mirror may
turn on even though there is no veh icle locatÂ
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. 114 with
stickers, depos its, bicycle wheels or other obÂ
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 214.
_&. WARNING
- Always pay attention to traffic and to t he
area a round your ve hicl e. S ide assist canÂ
not replace a driver's attention. T he drivÂ
er a lone is always responsible for lane
changes and similar driving mane uvers.

106 Audi side assist
-Improper reliance on the side assist sysÂ
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 unÂ
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 auÂ
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.

Improper care, servicing and repair proceÂ
dures can increase the risk of personal inÂ
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
~r the instrument panel or modify them
in anyway .
- 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 deÂ
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instruÂ
ment panel, front seats or electrical sysÂ
tem (including the installation of audio
equipment, cellular telephones and CB

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 workÂ
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 Â
ment upholstery over the front seatÂ
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 airÂ
bag module must always be repaired
Airbag system 165
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 authori zed 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 replaceÂ
ment parts designed and approved espeÂ
cially for your Audi model version . ReÂ
placement of complete airbag systems
or airbag components must be perÂ
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty

166 Airbag system
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag SysÂ
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 sp rings, suspenÂ
sion struts, shock absorbe rs etc. can change
the forces that are measured by the a irbag
sensors a nd sent to the electron ic control
un it. Some suspension changes ca n, for examÂ
p le, 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 measÂ
ured by the sensors and prevent the airbag
from deploying when it should .
A WARNING
Changing the vehicle 's s uspension includÂ
ing use of unapproved tire-rim combinaÂ
tions can change Advan ced Airbag perÂ
formance and increase the risk of serio us
personal injury in a crash.
- Never install suspens io n components
t hat do not have the same performance
characteristics as the components origiÂ
nally installed on your vehicle .
- Never use tire-rim combinat ions that
have not been approved by A udi.
A WARNING
-
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the

In addition to their normal safety f unction,
safety belts help keep the driver or front pasÂ
senger in position in a fronta l collision so that
the a irbags can provide supplemental protecÂ

The airbag system is not a substitute for your safety belt . Rather, it is part of the overa ll ocÂ
cupant restra int system in your vehicle. A lÂ
ways remember that the a irbag system can
only he lp to protect you if you are wearing
you r safety belt and wearing it properly. This
is why you should always wear your safety
belt, no t jus t because the law requires you to
do so
