Side assist (lane change assist) helps you mon itor
your blind spot and traffic behind your vehicle .
Within its lim its, the system warns you about
vehicles that are coming closer or that are travel­
ing within your sensor range
(D <=?fig. 109. If a
lane change is classified as critical, the display@
turns on in the exterio r mirror

are indicated, at the latest, by the time they en­
ter your "blind spot".
© Vehicles you are passing
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the
veh icle and your vehicle is less than approximate­
ly 9 mph (15 km/h)), the display in the exterior
mirror turns on as soon as the vehicle enters your
blind spot.
The display will not turn on if you quickly pass a
vehicle that side assist has detected (the differ­
ence in speed is greater than approximately 9 mph (15 km/h)).
Functional limitations
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
in the exterior mirror may turn on even though
there is no vehicle located in the area that is criti­
cal for a lane change. For example:
- If the lanes are narrow or if your are driving on
the edge of your lane. If this is the case, the system may have detected a vehicle in another
lane that is
not adjacent to your current lane.
- If you are driving through a curve. Side assist
may react to a vehicle that is in the same lane
or one lane over from the adjacent lane.
- If side assist reacts to other objects (such as
roadside structures like guard rails).
- In poor weather conditions . The side assist
functions are limited.
Do not cover the radar sensors ¢
fig. 112 with
stickers, deposits, bicycle racks or other objects,
because this will impair their function. Do not
use side assist when towing a trailer. For infor­
mation on cleaning, refer to¢
page 33 7.
A WARNING
- Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a driver's attention. The driver alone
is a lways responsible for lane changes and
similar driving maneuvers.
Assist
-In some 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 m ist.
- 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 adversely affect the sys­
tem. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their func­
tion.
(D Tips
If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be incor­
rect.

Airbag system
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the front
airbag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child against the backrest, center armrest, door
or roof.
- Always install rear-facing child safety seats
on the rear seat.
- If you must install a rearward -facing child
safety seat on the front passenger seat be­ cause of exceptional circumstances and the
PASSENGER AIR BAG OFF,;, light does not
come on and stay on, immediately install
the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your authorized Audi dealer .
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer ­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates.
- Never hold things in your hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area of
the front passenger seat . Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
- Never place or attach accessories or other
objects (such as cupholders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself . These objects
could cause injury in a crash, especially
when the airbags inflate .
- Never recline the front passenger's seat to
transport objects. Items can also move into
264
the area of the side airbag or the front air­
bag during braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined .
- Never place or transport objects on the
front passenger seat. Objects on the front
passenger seat could cause the capacitive
sensor in the seat to signal to airbag system
that the seat is occupied by a person when it
in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
worked without objects on the seat .
- Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that the seat is occupied by a person when it is
not , or to signal that it is occupied by some ­
one who is heavier than the person actually
sitting on the seat. The presence of an ob­
ject could cause the passenger front airbag
to be turned on when it should be off, or
could cause the airbag to work in a way that is different from the way it would have
worked without the object on the seat .
A WARNING
The fine dust created when airbags deploy can
cause breathing problems for people with a
history of asthma or other breathing condi­
tions .
- To reduce the risk of breathing problems,
those with asthma or other respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or opening win­
dows or doors.
- If you are in a collision in which airbags de­
ploy , wash your hands and face with mild
soap and water before eating.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches. ..,_

Airbag syste m
Make sure that the PASSENGER AIR BAG
OFF
11;; li ght comes on and stays on all t he
t ime whenever the ignition is switched on.
A WARNING
- If the PA SSEN GER AIR BAG OFF 11;; light
does not go out when an adult is si tting on
the front passe nger seat a fter ta king the
steps described above, make sure the adult is p roperly seated and restrained at one of
the rear seating positions.
- Have the airbag system inspected by your
authorized Aud i dealer before transporting
anyone on the front passenger seat.
@ Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenge r
side w ill be tu rned off, and the
PASSENGER
AIR BAG OFF

Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
different places on your Audi. Installing, remov­ ing, servic ing or repa iring a part in an area of the
ve hicle can damage a part of an airbag system
and prevent that system from working properly
i n a collision .
There are some important things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
env ironment.
A WARNING
Improper care, serv icing and repai r proce­
dures can increase the r is k of personal injury
and death by preventing an airbag from de­
ploying when needed or dep loying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the stee r­
ing wheel horn pad or airbag cover or the in­
strument pane l or modify them in any way.
268
- Never attach any objects s uch as c upholders
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag canno t deploy and p rotect
properly.
- Never repair, adjust , or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular telephones and C B radios, etc.)
m ust be perfo rmed by a qualified techn ician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly recommend that you see your au­
thorized A udi dealer or qualified workshop.
- Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repaired immedi­
ate ly by an autho riz ed Au di dealer.
- The a irbag system can deploy on ly once. Af­
ter an airbag h as been deployed, i t m ust be
repla ced with new replacement parts de­
signed and approved espec ia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be perfo rmed by qua lified workshops
only. Make su re that any airbag service ac­
tion is entered in your A udi Warranty
