it is necessary. Always follow traffic laws
regarding mainta ining a safe distance
between your vehicle and veh icles 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 in m ind that the radar sen ­
sor for pre sense front only works within defined detection zones, which means
other vehicles may not alw ays be detect­
ed correct ly.
- T he function and range of the radar sen­
sor c an be impaired by rain, snow and
heavy mist. Vehicles ahead may not be
detected right away, o r not detected at
all .
- Reflective surfaces such as guard rails or
entrances to t unnels may impair the
function of the radar sensor .
(D Note
The sensor 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 an authorized
Aud i dea ler or a uthori zed Audi Service Fa­
cility check their function.
(D} Tips
- You can cance l the braking with increas­
ing fo rce that is initiated by the system
by braking yo urself, by accelerating no­
ticeab ly or by swerving.
- For information on dr iver messages
about pre sense, refer to<=> page 97.
- Keep in mind that pre sense front can brake unexpectedly . Always secure any
cargo or objects that you are transport­
i ng to reduce the risk of damage o r in­
Jury .
- Certain pre sense front funct ions switch
off when ESC is sw itched off (sport
mode) or when driving in reverse .

-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 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.
(D Note
The sensors can be displaced by impacts or damage to the bumper, wheel housing and
underbody. This can affect the system. Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion.
@ 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

154 Airbag sys te m
- Always make su re that t here is nothing
on the front passenger seat that will
cause the capacitive passenge r 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 occ upied by someone who is heavier
than the person actu ally s itting on the
sea t. The presence of additiona l obje cts
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
PASSENGER AIR BAG
OFF
light comes o n 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
l o t of very important pa rts of the Advanced
A irbag System in it. These parts incl ude the
capacitive passenger detect ion sys tem, wir­
ing, brac kets, 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 indicator light on w hen a
malfunction i n the one of the system compo­
n ents is detected
c::;, page 159 . Because the
front passenge r seat contains important pa rts
of the Advanced Airbag System, you must
take ca re to pr even t it from be ing damaged.
Damage to the seat may preven t the Ad ­
vanced A irbag System for the front passenger
seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front o f the veh icle that
measure ve hicle acceleration/dece leration
to provide information to the Advanced Air­ bag System abo ut the severity of the crash .
- An electronic co ntro l unit, with i ntegrated
c rash sensors for f ront and side impacts.
The cont ro l unit "decides" whether to fire t
he front a irbags based on the in format ion
received from the crash sensors. The contro l
un it also "decides" whether the sa fety belt
pretens ioners sho uld be activated.
- An Advanced Airbag with gas generator fo r
the dr iver inside the steering wheel hub.
- An Advanced Airbag with gas gene rator in­
side the inst rument panel for the front pas­
senger.
- A capacit ive passenger detection system un­
derneath the front passenger seat cover.
This system measures the electrical capac i­
tance of the person in the seat. The informa­
tion registered is se nt cont inuous ly to the
elect ronic 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 t he i nstr ument cluster
¢ page 158.
-A senso r in each front seat registers the dis­
tanc e between the r espective seat and the
s teer ing whee l o r ins trumen t panel. The in­
form ation regis tered is sent cont inuo usly to
t he ele ct ron ic cont ro l unit to regula te de­
p loyment of the front Adv a need Ai rbags.
- The
PASSENGER AIR BAG OFF ligh t comes
on and stays on in the cen ter o f the instr u­
ment panel
c::;, page 214 and tells you when
the front Advanced Airbag on the passenger
side has been turned off.
- A sensor in t he safety be lt latch fo r th e d riv­
er and for the front seat passenger that
senses whether that safety belt is latched or not and transmits this information to t he
electronic control un it .
A WARNING
--
D amage to the fron t passenger seat can
p rev ent the fro nt airbag from wor king
prop erly.
- I mp rope r re pa ir or disassembly of the
fr ont passenge r and dr ive r sea t will pre­
ven t th e Adv anced Air bag System from
functioning p ro perly.
- Repairs to the front pa ssenge r seat must
be pe rformed by qualifie d and properly
trained workshop personnel.
