and road conditions. If necessary, apply the
brakes and reduce the selected speed to be
maintained in the Adjustment to curves
along route setting to reduce the risk of an

accident.

G) Tips
— Predictive control can exceed or drop below
the maximum permitted speed. The driver
is responsible for adhering to the permitted
speed limit.
— The traffic signs on the road always take pri-
ority over the display. The driver is always
responsible for adhering to the regulations
applicable in the country where the vehicle
is being operated.
— Ifa speed limit is detected, the marking @
= page 128 of the set speed limit will be ad-
justed even if Audi adaptive cruise control is
not actively regulating.
— Control by the system depends on which
adaptive cruise control driving program is
set or on the selected Audi drive select*
mode.
— After switching on the ignition and first
driving onto a freeway or similar road with-
out a speed limit, the system will regulate
the speed to 80 mph (130 km/h)). Then
the system adjusts to the last speed set by
the driver.
— There is no adaptation to speed limits when
driving through highway interchanges and
when driving on or off the expressway.
— The system can fail to provide control or the
control may be faulty if the values from the
camera-based traffic sign recognition” are
incorrect or the navigation system map data
is outdated.
— When route guidance is switched on, the
system adapts to the route provided by the
navigation system. Driving without route
guidance or leaving a route can result in
faulty control.

Audi adaptive cruise
control
General information
Applies to: vehicles with Audi adaptive cruise control
Depending on vehicle equipment, Audi adaptive
cruise control may consist of the following func-
tions:
Within the limits of the system, the adaptive
speed
and distance control assists the driver in
controlling the speed and the set distance to the
vehicle driving ahead. If the system detects a ve-
hicle driving ahead, the adaptive cruise control
can brake and accelerate your vehicle within the
limits of the system. On open roads with no traf-
fic, it functions like a cruise control system. The
stored speed is maintained. When approaching a
vehicle driving ahead, the adaptive cruise control
system automatically brakes to match that vehi-
cle's speed and then maintains the set distance
as much as possible. 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, the vehicle may brake to a
full stop and then may also start driving again
automatically under certain conditions.
Applies to: vehicles with traffic jam assist: In
traffic jams or in stop-and-go traffic, the traffic
jam assist can assist the driver to stay within the
lane detected by the system > page 134.
Applies to: vehicles with efficiency assist: Predic-
tive control can adjust the set speed based on
traffic and road conditions > page 126.

ZA WARNING
Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
G) Tips
For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see > page 275.

Fig. 112 Example: driving into a curve
In some situations, the adaptive cruise control
function is limited and you must assume control
of the vehicle when necessary, for example by ap-
plying the brakes.
— When driving into a curve > fig. 112 and out of
acurve, the system may react to a vehicle in the
neighboring lane and apply the brakes. You can
override the system by pressing the accelerator
pedal briefly.
— The system works with the various sensors and
cameras in the vehicle. Vehicles can only be de-
tected once they are within the area and range
covered by the sensors > page 115, fig. 104.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the system may ac-
celerate unexpectedly.
— The system does not react to a stationary vehi-
cle in the same lane if it expects that you can
easily drive around the stationary vehicle by
turning the steering wheel.
128
— The system cannot react to stationary objects,
such as vehicles at the end of a traffic jam, es-
pecially when traveling at high speeds.
— 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 vehicles with an overhanging load, may be
detected late or not detected at all.
— The system does not respond to people, ani-
mals, or objects that are crossing or approach-
ing from the opposite direction.

ZA\ WARNING
Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.

Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— The activated adaptive cruise control is only
an assist system, and the driver is still re-
sponsible for controlling the vehicle. The
driver is especially responsible for braking,
steering, starting to drive, and controlling
the speed and the distance from other
vehicles.
— Turn on the adaptive cruise control only if
the surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— 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.
— Ifyou press the [SETIQ) button when driving
at speeds below 15 mph (20 km/h)”, the
minimum possible speed that the system
can maintain will be set. If no vehicle is de-
tected ahead of you, the vehicle will acceler-
ate up to that speed.


(i) Tips
— Always keep your hands on the steering
wheel so you can be ready to steer at any
time. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.

— If you switch the ignition or the adaptive
cruise control system off, the set speed is
erased for safety reasons.
— When adaptive cruise control is switched
on, the ESC and ASR automatically switch
on.
— The system cannot be switched off or it may
be interrupted if the road exceeds the maxi-
mum possible grade for safe operation.
Setting the distance
Applies to: vehicles with Audi adaptive cruise control

B4M-0234


Fig. 117 Operating lever: setting the distance
If you adjust the speed, you must also change the
time gap to the vehicle driving ahead. The higher
the speed, the greater the distance that is need-
ed.
> Tap the rocker switch to display the distance
that is currently set.
> To increase or decrease the distance in incre-
ments, tap the switch again toward @) or G).
The newly-set distance will be shown briefly, for
example with the indicator light. In the Driv-
er assistance display, a graphic display is shown
instead of the indicator lights > page 128,
fig. 114. The display matches the functions of
the indicator lights.
When approaching a vehicle driving ahead, the
adaptive cruise control system brakes to match
that vehicle's speed and then adjusts to the set
distance. If the vehicle driving ahead accelerates,
then the adaptive cruise control will accelerate
up to the speed that you have set.
The following distances can be set:

Meaning

The time between is approximately 1
eee second. This setting corresponds toa
= distance of approximately 92 feet (28
m) when traveling at 62 mph (100
km/h).
The time between is approximately 1.3
seconds. This setting corresponds toa
distance of approximately 118 feet (36
m) when traveling at 62 mph (100
km/h).
The time between is approximately 1.8
seconds. This setting meets the general
recommendation of “half the speed
shown on the speedometer”. This cor-
responds to a distance of approximate-
ly 164 feet (SO m) when traveling at
62 mph (100 km/h).
The time between is approximately 2.4
seconds. This setting corresponds to a
distance of approximately 219 feet
(67 m) when traveling at 62 mph (100
km/h).
The time between is approximately 3.6
seconds. This setting corresponds toa
distance of approximately 328 feet
(100 m) when traveling at 62 mph (100

In a speed range under 40 mph (65 km/h), the
system can help to keep the vehicle within a lane
calculated by the system. Within the limits of the
system, the system controls the steering auto-
matically when adaptive cruise control is switch-
ed on. Since traffic jam assist is only an assist
system, the driver must always keep his or her
hands on the steering wheel and be ready to
steer. The driver can override the control at any
time by actively steering.
The system is designed for driving on express-
ways and highways.
