Driver assistance


— 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.
— When a route is planned using the naviga-
tion system*, then system displays messag-
es based on an assumed route. Without
route guidance, the system displays mes-
sages based on an assumed route.
— The wording of the message may vary de-
pending on the selected Audi drive select*
mode and the selected gear. No messages
are displayed when in the "S" driving pro-
gram.
Adaptive cruise assist
(eee ieleur isola)
Applies to: vehicles with adaptive cruise assist

Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
Within the limits of the system, the adaptive
speed assist assists the driver in controlling the
speed and the set distance to the vehicle driving
ahead. If the system detects a vehicle driving
ahead, the adaptive speed assist can brake and
accelerate your vehicle within the limits of the
system. On open roads with no traffic, it func-
tions like a cruise control system. The stored
speed is maintained. When approaching a vehicle
driving ahead, the adaptive speed assist auto-
matically brakes to match that vehicle's speed
and then maintains the set distance as much as
possible. Once the system does not detect a vehi-
cle driving ahead, adaptive speed assist will ac-
celerate up to the set speed.
The additional lane guidance assists the driver
with corrective steering in order to stay in the
lane. You can adjust if the adaptive cruise assist
will provide support with lane guidance
= page 141, Switching lane guidance on and off.
In stop-and-go traffic and in traffic jams, the ve-
hicle may brake to a full stop and then may also
138

start driving again automatically under certain
conditions.
Applies to: vehicles with efficiency assist: Predic-
tive control can adjust the speed based on traffic
and road conditions > page 142, Predictive con-
trol.

ZA WARNING
Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 122.
@ Tips
The system complies with United States FCC
regulations and ISED regulations > page 311.

Fig. 98 Example: driving into a curve
In some situations, the adaptive cruise assist
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. 98 and out of a
curve, 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 123, fig. 89.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the adaptive cruise
assist may accelerate 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.
— 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.

) Analog instrument cluster: 20 mph (30 km/h)
If the malfunction remains, drive to an author-
ized Audi dealer or authorized Audi Service Facili-
ty immediately to have the malfunction correct-
ed.

A WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 122.
— Pay attention to traffic and the area around
your vehicle when predictive control is
switched on. The driver is always responsible
for assessing the traffic situation.
—The system does not consider “right of way”
rules and does not respond to traffic lights,
so lack of driver attention in these situations
can increase the risk of an accident.
— The speed when driving through curves may
be different from what you as a driver would
do or may not be suitable for the weather
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.
@) 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 @
of the set speed limit will be adjusted even
if the adaptive cruise assist is not actively
regulating.
— Control by the system depends on which
adaptive cruise assist 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

143

Driver assistance

without a speed limit, the system will regu-
late 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.
