2015 AUDI S3 SEDAN sensor

Light and Vision
When switched on, adaptive light adjusts to
curves depending on the vehicle speed and steer·
ing wheel angle . This provides better lighting
through the curve. The system operates in a
speed range from approximately 6 mph (10 km/
h) to 68 mph (110 km/h).
Static cornering light* (vehicles with adaptive
light)· the cornering light switches on automati­
cally when the steering wheel is turned at acer­
tain ang le at speeds up to approximately 44 mph
(70 km/h) and whe n the turn signal is activated
at speeds up to approximately 25 mph (40 km/
h). The area to the side of the vehicle is illuminat­
ed better when tu rning.
Speed depend ent light distribution* -The speed
dependent light distribution adapts the light in
towns and on highways or expressways. In tersec­
tions can also be illum inated on veh icles with a
navigat ion system*.
Highway light function*
(Vehicles with adaptive light or LED headlights) -
This function adapts the light ing for highway
driving based on vehicle speed .
..&, WARNING
-Automatic headlights* are only int ended to
assist the driver. They do not relieve the
driver of his responsibility to check the
headlights and to turn them on manually
according to the current light and visibi lity
condit ions. For example, fog cannot be de·
tected by the light sensors . So always switch
on the low beam under these weather con­
ditions and when driving in the dark
io.
- Accidents could occur if you can not see the
road ahead of you well and if others on the
road cannot see you . Always switch your
head lightsonsothatyoucanseetheroad
ahead of you and others can see your vehicle
from behind.
- Please observe legal regulations when using
the lighting systems described .

(D Note
The rear fog lights shou ld only be turned on in
accordance with traffic regulation, as the lights are bright for following traffic.
@ Tips
-The light sensor for the automatic head­
lights * is in the rearview mirror mount.
Therefore, do not place any stickers in this
area on the windshield.
- Some functions of the exterior lighting can
be adjusted
c> page 45.
- If you turn off the ignition whi le the exterior
lights are on and open the door, you will
hear a warning tone.
- In some market-specific versions, the tail
lights do not turn on when switching on the
daytime running lights.
- In cool or damp weather, the inside of the headlights, turn signals and taillights can
fog over due to the temperature difference
between the inside and outside . They will
clear shortly after switching them on. This
does not affect the serv ice life of the light­
ing .
- A message will appear in the instrument
cluster if there is a malfunction in the light
sensor

tion is turned off.
@ Tips
Yo u should switch the emergency flashers on
if:
- You are the last car in a traffic jam so that
all other vehicles approaching from behind
can see you, or if
- Your vehicle has broken down or you are
having an emergency, or if
- Your vehicle is being towed or if yo u are
towing another vehicle.

- The rain sensor is only intended to assist the
driver. The driver is still responsible for manually switch ing the w ipers on according
to the visibility cond itions.
- The windshield may not be treated with wa­
ter-repelling w indshield coat ing agents. Un­
favorable conditions, such as wetness, dark­
ness, low sun, can result in increased glare.
W iper blade chatter is also possib le.
- Properly function ing windsh ield wiper

shield wiper blades .
(D Note
- In the case of frost, check whether the
windshield wiper blades are fr ozen to the
w indshield. Switching on the w indshield
w ipers can damage the w iper blades!
- Prior to using a car wash, the windshield
w iper system must be sw itched off (leve r in

Light and Vi sion
- Do not use the wipers to remove ice from
the windows. Using windshie ld wipers as ice
scrapers destroys the wiper blades.
(D Tips
- The windshield wipers are switched off
when the ignition is turned off. Activate the
windsh ield wipers after the ignition is
switched back on by moving the windsh ield
wiper lever to any pos it ion.
- Worn or dirty windshie ld wiper b lades result
i n streaking. This can affect the rain sensor
funct ion. Check your windshield wiper
blades regularly .
- The washer fluid nozzles in the w indshield
washer system are heated* at low tempera­
tures when the ignit io n is on.
- When stopp ing temporarily, such as at a
traffic light, the speed of the windsh ield
wipers automatically reduces by one level.
- In vehicles with an MMI, you can switch the
rain sensor or off in the
Dri ver ass istanc e
menu.

General information
Applies to vehicles: with Audi adaptive cruise control and Audi
pre sense front
Fig. 81 Front of vehicle: sensor
The general information applies to adaptive
cruise control* and pre sense front*
r::!>page 103.
The radar sensor area r::!> fig. Bl must not be cov­
ered with stickers, deposits or any other obstruc­
tions as it may impair the function of the adap­
tive cruise control and the pre sense front. For in­
formation on cleaning, refer tor::!>
page 235. The
same applies for any modifications made in the
front area .
The function of the adaptive cruise control sys­ tem and pre sense front is limited in some condi­
tions :
- Objects can only be detected when they are
within the sensor ranger::!>
page 96, fig. 80.
-The system has a limited ability to detect ob­
jects that are a short distance ahead, off to the side of your vehicle or moving into your lane.
- Objects that are difficult to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
- When driving through curves
r=> page 98.
-With stationary objects r::!> page 98.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and the pre
sense front is active
r::!> page 103. As the d riv­
er, you are still responsible for starting and
for maintaining speed and distance to other objects. The pre sense front is used to assist
you. The driver must always take action to
Assist
avoid a collision. The driver is always responsi­
ble for braking at the correct time.
- Using adaptive cruise control incorrectly can
cause collisions, other accidents and serious
injuries.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing). Using the system under these condi­
tions could result in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situations.
- The adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and pre sense front will
have limited function.
- The adaptive cruise control system and pre
sense front do not react to people, animals,
objects crossing the road or oncoming ob­
jects.
- The function of the radar sensors can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
- Always maintain enough distance from
vehicles ahead so that you can still brake
your vehicle safely. The adaptive cruise con­ trol cannot safely slow your vehicle or brake it to a stop if you are driving too close be­
hind a vehicle. Please note that the auto­
matic braking function cannot brake sud­
denly or apply the brakes fully under these
conditions.
- To reduce the risk of unintended actions,
switch the ACC off when you are not actively
using it.

Assist
(D Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. The adaptive cruise control and
pre sense front may become impaired as a re­
sult. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their func­
tion.
In curves
Applies to vehicles: with Audi adaptive cruise control and Aud i
pre sense front
Fig. 82 Example: driving into a curve
When driving into a curve~ fig. 82 and out of a
curve, the adaptive cruise control may react to an
object in the neighboring lane and apply the
brakes. You can prevent that by pressing the ac­
celerator pedal briefly .
Stationary objects

pre sense front

ject

Adaptive cruise control
The adaptive cruise control system only reacts to
objects that are moving or that the system has
already detected as moving. For example, it can
react when a vehicle that has already been de­
tected @turns or changes lanes, but adapt ive
cruise control does not react to a stationary vehi­
cle @. Press the brake pedal to slow your vehicle
down!
Pre sense front
Pre sense front only reacts to stationary objects
at low speeds.
