it is necessary. A lways follow traffic laws
regarding mainta ining a safe distance
between your vehicle and vehicles ahead.
- pre sense front works within certain lim­
its and cannot react to situations that
are outside of the system lim its, such as
when approaching a stationary vehicle or
a stationary obstacle (the end of a traffic
jam or a vehicle that has broken down).
-Always keep i n m ind that the radar sen­
sor fo r pre sense front only works within
defined detection zones, which mea ns
other vehicles may not always be dete ct­
ed correct ly.
- T he function and range of the radar sen­
sor can be impaired by rain, snow and
heavy mist. Veh icles ahead may not be
detected right away, or not detected at
all.
- Reflective surfaces such as g uard rails or
entrances to t unnels may impair the
function of the radar sensor .
{[) Note
The senso r can be disp laced by impacts or
damage to the bumper, whee l housing and
underbody . The pre sense front sensor can
be damaged by this . Have your authorized
Aud i dea ler or authorized service facility
check the ir function.
(D Tips
- You can cance l the braking w ith increas­
ing force that is initiated by the system
by braking yourself, by accelerating no­
ticeab ly or by swerving.
- For information on dr iver messages
about pre sense, refer to¢ page 96.
- Keep in mind that pre sense can brake unexpectedly. Always secure any cargo or
objects that you are transporting to re­
duce the r isk of damage or injury .
- Certain pre sense front funct ions sw itch
off when ESC is sw itched off (sport
mode) or when drivi ng in reve rse .
- The pre sense front funct ions are not
available if there is a malfunction in the adaptive cru
ise cont ro l* system

I AU DI
Fi g. 93 Rear of ve hicle: se nsor pos it ions
Side assist functions at speeds above app rox i­
mately 19 mph (30 km/h) .
@Vehicl es that 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, t he sooner the display in the exteri ­
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 indi cated by the time they en­
t er your "blind spot", at the latest.
Aud i side assist 103
© Veh icles 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 ro r
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).
Functional limitations
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lan es are the normal width . In some sit ua­
tions, the d isp lay in the exterior mirror may
turn on even though there is no ve hicle locat­
ed in the area that is cr itical for a lane cha nge.
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 the vehicle in
another lane that is
not adjacent to you r
current lane .
-If you are dr iving through a curve . S ide as ­
sis t may react to a vehicle that is one lane
over 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 limited .
Do not cover the radar sensors
c> fig. 93 w ith
stickers, depos its, bicycle wheels or other ob­
jects, because this will affect the funct ion. For
information on cleaning, see
c> page 205.
A WARNING
- Always pay attention to traffic and to the
a rea a round your ve hicl e. Side assi st can­
not repla ce a d river's attention . Th e driv ­
er a lone is always responsible for la ne
cha nges and s imilar dr iv ing ma ne uvers.
- In some si tua tions, the system may not
function or its function may be limited.
F or examp le:

104 Audi side assist
-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.
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range.
- Audi side assist cannot detect all vehicles
under all conditions, which can increase
the risk of accidents.
- Please note that side assist only displays
approaching vehicles or vehicles in your
blind spot if your vehicle is traveling at
least 19 mph (30 km/h).
- In certain situations, the system may not
work or its function may be limited. For
example:
- The display may not turn on at the
right time if vehicles are approaching
or passing very quickly.
- In poor weather conditions, such as
heavy rain, snow or fog.
- In very wide lanes, in tight curves or
when there are slopes in the roadway,
vehicles in the neighboring lanes may not be detected because they are out­
side of the sensor range.
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 service facility check their func­
tion.
{D) 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

152 Airbag sys te m
cause the capacitive passenger detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a person when it is not, or to signal that it
is occupied by someone who is heavier
than the person actually s itting on the
seat. The presence of additional objects
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause the airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat.
- Make sure that the
PA SSENGER AIR BAG
OFF
light comes on and stays on all the
t ime whenever the ignition is switched
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
lot of very important parts of the Advanced
A irbag System in it . These parts include the
capacitive passenger de tect ion system, wir­
ing, b ra ck ets, and more. The cont ro l unit
monitors the system on the front passenger
seat when the ign ition is switched on and
turns the airbag indicato r light on when a
malfunction in the one of the system compo­
nents is detected¢
page 157 . Because the
fro nt passenger seat contains important parts
of the Advanced Airbag System, you must
take care to prevent it from being damaged .
Damage to the seat may prevent the Ad­
vanced A irbag System for the front passenger
se at from doing i ts job in a c rash.
The front Advanced Airbag System
consists of the following:
- Crash sensors in the fro nt of the ve hicle that
m easure ve hicle accelera tion/de celera tion
to provide info rmation to the Advanced Air­
bag System abo ut the seve rity of the crash.
- An electronic cont ro l u nit, with integrated
c rash sensors for front and side impacts.
The cont ro l unit "decides" whether to fire
the front airbags based on the information received from the crash sensors. The contro l unit also "decides" whether the sa
fety belt
pretensioners sho uld be activated.
- An Advanced A irbag w ith gas generato r for
the driver inside the steering wheel h ub.
- An Advance d Airbag w ith g as generato r in­
side the inst rument panel for the front pas ­
senger.
- A capacit ive passenger detection system un­
de rneath the front passenger seat cover .
This system meas ures the electrical capac i­
tance of the person in the seat. The informa ­
tion registered is sent cont inuo usly to the
electronic control un it to regu late deploy­
ment of the front Advanced A irbag on the
passe nger side .
- An airbag monitor ing system and indicator
light in the instrument cluster¢
page 156 .
-A sensor in each front seat registers the dis­
tance betwee n the respective seat and the
steer ing whee l o r inst rument panel. The in­
formation registered is sent cont inuous ly to
t he ele ct ron ic contro l unit to regula te de­
p loyment of the front Adva nced A irb ags .
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of t he instr u­
ment p anel ¢
page 217 and t ells yo u when
the fron t Advanced Airbag on the passenge r
side has been turned off.
- A sensor in the safety be lt latch for the driv ­
er and for the front seat passenger that
senses whether t hat safety belt is latched or
not and transmits this information to the
electronic control un it.
A WARNING
Damage to the front passenger seat can
prevent the front airbag from wor king
p roperly.
- Improper repair or d isassembly of the
front passenge r and dr iver sea t will pre­
vent the Advanced Airbag System from
functioning p roperly.
- Repairs to the front passenge r seat must
be pe rformed by qualified and p roperly
trained workshop personnel.
- Never remov e the front passenger o r
d river seat from the vehicle.
-
