:E Audi adaptive cruise control
Description
Applies to: vehicles with Audi adaptive cruise control
Fig. 100 Detect ion range
The adaptive cruise control system is a combina­
tion of speed and distance regulation.
It assists
the dr iver by both regulat ing the speed and
maintaining a distance to the vehicle driving
ahead, within the limits of the system .
If the sys­
tem detects a vehicle driving ahead, the adaptive
cruise control can brake and accelerate your vehi­
cle. This makes dr iving more comfortable both
on long stretches of highway and in stop-and-go
traffic.
What can adaptive cruise control do?
The adaptive cruise control system uses video, ra­
dar, ultrasound and navigation data. Vehicles
driving ahead can be recognized up to
650 feet
(200 m) away.
Predictive funct ions offer the driver additional
comfort and contribute to the reduction in fuel
consumption and CO2 emissions
¢page 113.
On open roads with no traffic, it functions like a
cruise control system. The stored speed is main­
tained. When approaching a vehicle driving
ahead, the adaptive cruise control system auto­
matically brakes to match that vehicle's speed
and the n maintains the set distance. As soon as
the system does not detect a vehicle driving
ahead, adaptive cruise control accelerates up to
the stored speed.
In stop-and-go traffic, adaptive cru ise control ca n
brake until the vehicle is stationary and then can
Assistance systems
also start driving again automatically under cer­
tain conditions
¢page 110.
In traffic jams or stop-and-go traffic, traffic jam
ass ist can assist the driver¢
page 114.
Which functions can be controlled?
When you switch adapt ive cruise control on, you
can set the current speed as the "control speed"
¢page 109, Switching on/off.
When driving, you can stop cruise control
¢page 111 or change the speed <::;>page 110 at
any time.
You can also set the distance to the vehicle driv­ ing ahead and set the driving mode of the adap­
tive cruise control¢
page 111.
General information
Applies to: vehicles with Audi adaptive cruise control
Fig. 101 F ront of the vehicle : sensors and video camera
The areas with the radar and ultrasonic sensors
and the video camera
i::> fig . 101 must not be cov­
ered by stickers, depos its or any other objects,
because this can interfere with the adaptive
cruise control function. For informat io n on clean­
ing, see<::;>
page 354. The same applies for any
modifications made in the front area.
In some driving situations, the adaptive cruise
control function is restricted:
- Vehicles can only be detected when they are
with in the sensor detection zones<::;>
page 107,
fig . 100.
- The system has a limited ability to detect
vehicles that are a short distance ahead, off to
the side of your veh icle or moving into your
lane .
107

Assistance systems
-Objects that are difficult to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhang ing load are detected late or not
detected at all.
- When driving through curves
c:;, poge 108.
-When the vehicle is stationary r::;, page 108.
_& 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 the road surface is in
poor condition and/or in bad weather condi­
tions (such as ice, fog, gravel, heavy rain and
hydroplaning). Using the system under
these conditions increases the risk of an ac­
cident.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits (except if predictive control
is switched on) or in construction zones.
This prevents the vehicle from accelerating
to the stored speed when in these situa­
tions.
- 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 obstacles
such as stopped traffic, adaptive cruise con­
trol will respond with limited function.
- 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.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
108
underbody. This can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check their
function.
(D Tips
For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
c:;, page 384.

tive occupant protection are can be initiated.
- The
pre sen se fro nt system uses the data from
the adapt ive cruise control* radar sensors and
the camera to calculate the probability of a col­ lis ion. Within the limits of the system, an im­
pending collision with vehicles can be detected
i n both urban and rural speed ranges. In this
case, the system warns the dr iver visually,
acoustically and with a jerk on the brakes if nec­
essary.
If needed, it can initiate a pa rtial or fu ll
deceleration to reduce the co llision speed or to
avoid the collision under certain circumstances .
In conjunction with pre sense basic/rear, the
front safety belts are also reversibly tensioned
when needed. The pre sense front is also active
when adapt ive cruise control* is switched off.

:E: ' Audi pre sense city
Description
Appl ies to: ve hicles with Audi pre sense c ity
W ith in the limits of the system, pre sense c ity
can warn you of impending coll is ions w ith
vehicles and pedestrians and initiate the applica­
b le braking maneuver if needed. Pre sense city is
active at speeds of approximately 6 mph (10 km/ h) and higher.
A pedestrian warning can occur at speeds up to
50 mph (85 km/h), and vehicle warnings can oc­
cur at speeds up to 155 mph (250 km/h). A pre
sense city braking maneuver is possible at speeds
up to SO mph (85 km/h).
Warnings
A ppl ies to: ve hicles with Audi pre sense c ity
The system recognizes various dangerous situa­
tions . The
early warning occurs if:
- a vehicle driving ahead brakes suddenly,
- your own vehicle approaches a significantly
slower vehicle or stationary vehicle in the direc­
tion of travel.
- a pedestrian is standing in the lane or is moving
into the lane.
When this warning occurs, it may only be possi­ ble to avoid a collision by swerving or braking
strong ly. The message
Audi pre sense.
¢ page 119, fig. 115 and a warning tone will
warn you about the danger .
Additionally, a jerk on the brakes may occur as an
acute warning when there is an impending colli­
sion. If you do not react to the acute warning, pre
sense city can brake to the point of complete de­
celeration within the limits of the system. This reduces the vehicle speed in the event of a colli ­
sion. The message
Audi pre sense. also ap­
pea rs .
The following functions are triggered in conjunc­
tion with pre sense basic/rear:
- Revers ible tensioning of the front safety belts .
- Closing the windows and sunroof*.
- Inflating the side bolste rs* in the seat backrest
and seat surface.
