General information
Appl ies to: ve hicles with Audi adaptive cruise contro l an d Audi
p re se nse front
Fig. 88 Front of vehicle: sensor
The general information applies to adaptive
cruise control* and pre sense front*
i::;, page 97.
The radar sensor area
i::!:> fig. 88 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 to
c> page 224. 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 range ¢
page 90, fig. 87.
-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'=>
page 92.
- With stationary objects ¢
page 92.
A WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and the pre
sense front is active
'=> page 9 7. As the driv­
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 a re not actively
using it.

Audi pre sense
Introduction
Applies to: vehicles with Audi pre sense basic or Audi pre
sense front
Within the limits of the system, pre sense basic
and pre sense front can initiate steps to protect
vehicle occupants in certain dangerous situa­
tions.
Critical driving situations can be recognized by
the pre sense front via a network of different ve­
hicle systems and can take steps to prepare the
vehicle occupants for a potential collision.
The pre sense front works with a radar sensor
and a video camera*. It also functions within the
limits of the system when adaptive cruise con­
trol* is switched off.

A WARNING
Also follow the general information found on
~ page 91, General information.
Audi pre sense basic
Description
Applies to: vehicles with Audi pre sense basic
The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or higher.
The following functions can be triggered under
certain conditions within the limits of the sys­
tem:
- Tensioning of the safety belts (for examp le,
during heavy braking): the front safety belts have reversible belt tensioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger again.
- Closing the windows (for example when over­
or understeering): the windows close until
there is a small gap open.
Audi drive select: the deployment time is adapt­ ed in dynamic mode.
A WARNING
-The pre sense basic cannot overcome natural
physical laws. It is a system designed to assist
and it cannot prevent a collision. Do not let
the increased safety provided tempt you into
taking risks. This could increase your risk of a
collision.
- The system can dep loy incorrectly due to
system-specific limits.
@ Tips
-Certain pre sense basic functions switch off
when ESC is switched off (sport mode) or
when driving in reverse.
97

<( co .... N r--­N .... 0 r--­> co
-Please note that the sensor does not always
detect all objects . This increases the risk of
a collision.
- Pre sense front does not react to people or
animals or objects that are crossing the ve­
hicle's path or are difficult to detect
¢ page 91 .
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensor and
the system's ability to detect a collision risk.
- Lack of attention can lead to collisions, oth ­
er accidents and serious injuries. pre sense
front is an assistance system and cannot
prevent a collision by itself. The driver must
always intervene . The driver is always re­
sponsible for braking at the correct time.
- Always pay attention to traffic , even when
pre sense front is switched on. Always be
ready to intervene and take over complete
control of the vehicle whenever it is neces­
sary. Always follow traffic laws regarding
maintaining a safe distance between your
vehicle and vehicles ahead.
- pre sense front works within certain limits
and cannot react to situations that are out­
side of the system limits, such as when ap­
proaching a stationary vehicle or a station ­
ary obstacle (the end of a traffic jam or ave­
hicle that has broken down).
- Always keep in mind that the radar sensor
for pre sense front only works within de­
fined detection zones , which means other
vehicles may not always be detected cor­
rectly.
- The function and range of the radar sensor
can be impaired by rain, snow and heavy
mist. Vehicles ahead may not be detected
right away, or not detected at all.
(1) Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. Pre sense front can be impaired
by this. Have an authorized Audi dea ler or au­
thorized Audi Service Facility check their func­
tion .
Assist
{!) Tips
-You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving.
- For information on driver messages about
pre sense, refer to
¢ page 100.
- Keep in mind that pre sense front can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.
- Certain pre sense front functions switch off
when ESC is switched off (sport mode) or
when driving in reverse.
- The pre sense front functions are not availa­
ble if there is a malfunction in the adaptive
cruise control* system
Q page 96 or
Q page 100 .
-Keep in mind that pre sense front can brake
abruptly . Always secure cargo or objects
that you transport to reduce the risk of
damage or injury.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It i s becom ing increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are ab le to get to the bulb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
