The radar sensor area > fig. 109 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 or the pre sense front. For in-
formation on cleaning, see > page 342. The
same applies for any modifications made in the
front area.
The function of the adaptive cruise control sys-
tem or pre sense front is limited in some condi-
tions:
— Vehicles can only be detected when they are
within the sensor range > page 118, fig. 108.
—The system has a limited ability to detect
vehicles 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 120.
— When the vehicle is stationary > page 120.


Z\ WARNING
Always pay attention to the traffic around you
when adaptive cruise control is switched on.
As the driver, you are still responsible for your
own speed and the distance to other vehicles.
The adaptive cruise control is used to assist
you. The driver must always take action to
avoid a collision. The driver is always responsi-
ble for braking at the correct time.
— 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 temporari-
ly when driving in turning lanes, on express-
way exits or in construction zones. This pre-
vents the vehicle from accelerating to the
stored 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.
— Adaptive cruise control does not respond to
people, animals, or crossing or oncoming
objects.
— 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

@) Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check their
function.

Audi pre sense
Introduction
Applies to: vehicles with Audi pre sense
Within the limits of the system, the pre sense
functions can initiate measures in particularly
dangerous situations to protect the vehicle pas-
sengers and other road users.
— Due to the interlinking of various vehicle sys-
tems, critical driving situations can be detected
by pre sense basic and measures for preventa-
tive occupant protection are can be initiated.
— The pre sense front uses the data from the ra-
dar sensors and calculates the probability of an
accident > page 119. An impending collision
with vehicles can be detected within the limits
of the system. In this case, the system warns
the driver visually, acoustically and with a jerk
on the brakes if necessary. If needed, it can ini-
tiate a partial or full deceleration to reduce the
collision speed or to avoid the collision under
certain circumstances. In conjunction with pre >

Assist systems

strongly. The message Audi pre sense A
=> fig. 120 and a warning tone will warn you
about the danger.
If there is an impending collision with vehicles,
there will also be an acute warning in the form of
sharp braking. If you do not react to the acute
warning, pre sense front can brake with increas-
ing force within the limits of the system. This re-
duces the vehicle speed in the event of a colli-
sion.
Automatic deceleration
Depending on the speed, pre sense front can de-
celerate automatically shortly before a collision:
— if there are stationary vehicles when you are
traveling at speeds up to approximately 28
mph (45 km/h)
— if there are vehicles driving or stopped ahead
when you are traveling at speeds up to approxi-
mately 155 mph (250 km/h)
Automatic braking force increase
If pre sense front determines that you are not
braking strongly enough when a collision is immi-
nent, it can increase the braking force, depending
on the situation and speed:
— if there are stationary vehicles when you are
traveling at speeds up to approximately 50
mph (85 km/h)
— if there are vehicles driving or stopped ahead
when you are traveling at speeds up to approxi-
mately 155 mph (250 km/h)

— The system can deploy incorrectly due to
system-specific limits.
— 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 vehicles
traveling toward you in the same lane, to
people, groups of people, animals, objects
that are crossing the road, or objects that
are difficult to detect > A\ in General infor-
mation on page 119.



ZA\ WARNING
Pre sense front may be restricted or not avail-
able in the following example situations:
— If there are other reflective objects nearby,
such as guard rails or vehicles
— When driving into a tunnel
— In heavy fog, rain, spray, or snow
—If the radar sensor is dirty, covered in ice,
damaged, or covered
— In curves
— If the ESC was switched off.


Z\ WARNING
Pre sense front cannot overcome the laws of
physics. It is a system designed to assist and
it cannot prevent a collision in every circum-
stance. The driver must always intervene. The
driver is always responsible for braking at the
correct time. Do not let the increased safety
provided tempt you into taking risks. This
could increase your risk of a collision.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.

@) 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 dealer or au-
thorized Audi Service Facility check their func-
tion.
(i) 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.
— When driving in reverse, certain pre sense
front functions are switched off.
— System functions may not be available if the
ESC is limited or switched off, or if there is a
malfunction.

are approaching a detected lane marker line and
it appears likely that you will leave the lane, the
system will warn you with corrective steering.
You can override this steering at any time. If you
pass over a line, the steering wheel will vibrate
lightly. In order for this warning vibration to oc-
cur, it must first be switched on in the Infotain-
ment system. Active lane assist is ready for oper-
ation when the lane marker line is detected on at
least one side of the vehicle.
The system is designed for driving on express-
ways and highways and therefore only activates
at speeds above approximately 40 mph (65
km/h).
Applies to: vehicles with Audi side assist
If you activate a turn signal when active lane as-

Fig. 127 Rear of the vehicle: position of the sensors
Side assist functions at speeds above approxi-
mately 9 mph (15 km/h).
@ Approaching vehicles
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some-
what far away. The faster a vehicle approaches,
the sooner the display in the outside mirror will
turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
are indicated by the time they enter your “blind
spot”,
at the latest.
@ Vehicles you are passing
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the ve-
hicle and your vehicle is less than approximately
9 mph (15 km/h)), the display in the exterior mir-
ror 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:
