— Obstacles may disappear from the measure-
ment range when approaching them, even if
they were already detected. Under certain
circumstances, the detection and display of
certain surfaces and objects may be limited:
— Items and objects above the coverage
area, for example cars parked bumper-to-
bumper, half-open garage doors, or hang-
ing objects that do not touch the ground
— Low obstacles

@) Tips
— The coverage areas of the sensors > fig. 85
are diagrams and do not represent a true-
to-scale image of the sensor ranges. The ra-
dar sensors are designed to detect the left
and right adjacent lanes when the road
lanes are the normal width.
— The sensors and the areas around them
must not be obstructed because this can im-
pair the function of the systems that de-
pend on them. Make sure that the sensors
are free of snow, ice, and other deposits. Do
not use any accessories, stickers, or other
objects that extend into the range of the
sensors.
— Do not use a license plate bracket different
from the one installed by the factory in the
front of the vehicle, because it may impair
the function of some systems.
— The sensors can shift from an accident,
manual force, impacts, or from damage to
the radiator grill, bumper, wheel housing,
or underbody. Do not continue using the as-
sistance systems if the sensors have shifted,
because this is unsafe. Have an authorized
Audi dealer or authorized Audi Service Fa-
cility check their function.
— The function of the sensors may be limited
when light and visibility conditions are poor,
for example when driving into a tunnel,
when there is glare, or when there are re-
flective objects.
— External ultrasonic sensors, such as those in
other vehicles, can interfere with the sen-
sors.
—The side area ©)* is detected and evaluated
when passing. There may have been
changes to the surrounding area after
switching the ignition off and on again, af-
ter opening the doors, or if the vehicle is left
stationary for a period of time. In this case,
the area will appear black until the area has
been detected and evaluated.

Driving information
Driving information
Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps the driver to
stay below a specified maximum speed. A warn-
ing threshold can be set for this purpose.
Once the speed slightly exceeds the stored
threshold, the speed warning system will alert
the driver with an indicator in the instrument
cluster and a warning tone. Once the speed drops
below the stored maximum speed, the indicator
will turn off.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
al speed limit or if there is a specified maximum
speed for winter tires.
G) Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.
Setting the warning threshold

the navigation data’ is.
— Outdated map content in the navigation
system* can cause information on the dis-
play to be omitted or incorrect.
— Certain traffic lights can automatically ad-
just to the current traffic situation. If this
occurs, the display of traffic light informa-
tion can change suddenly.
— 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.

Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.
ZA\ WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.
() Note
Before driving downhill a long distance ona
steep hill, decrease your speed and select a
lower gear. This makes use of the engine brak-
ing effect and reduces the load placed on the
brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.

Adaptive speed/cruise
assist
General information
Applies to: vehicles with adaptive cruise assist
Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
The adaptive speed/cruise assist (called only
adaptive cruise assist in the vehicle display and in
the rest of the Owner's Manual) consists of a
speed and distance control system. It assists the
driver by both regulating the speed and main-
taining the set distance to the vehicle driving
ahead, within the limits of the system. If the sys-
tem detects a vehicle driving ahead, the adaptive
cruise assist can brake and accelerate your vehi-
cle within the limits of the system. On open roads
with no traffic, it functions like a cruise control
system. The stored speed is maintained. When
approaching a vehicle driving ahead, the adaptive
cruise assist automatically brakes to match that
vehicle's speed and then maintains the set dis-
tance as much as possible. As soon as the system
does not detect a vehicle driving ahead, adaptive
cruise assist accelerates up to the set speed.

responsible for controlling the vehicle. The
driver is especially responsible for braking,
starting to drive, controlling the speed, and
maintaining the distance to other vehicles.
— Turn on the adaptive cruise assist only if the
surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch the adaptive cruise assist off tempo-
rarily when driving in turning lanes or high-
way exits. This prevents the vehicle from ac-
celerating to the stored speed when in these
situations.
ZA WARNING
If you press the SETK2) button when driving
at speeds below 20 mph (30 km/h), then 20
mph (30 km/h) will be set because that is the
minimum speed that can be set. If no vehicle
is detected ahead of you, the vehicle will ac-
celerate up to that speed.
@ Tips
— Always keep your hands on the steering
wheel. 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 assist off, the stored speed is erased
for safety reasons.
— When the adaptive cruise assist is switched
on, the ESC and the ASR are switched on au-
tomatically.
— The system cannot be switched off if the
road exceeds the maximum possible grade
for safe operation.
— If you signal to pass and the adaptive cruise
assist suggests a passing maneuver, the
adaptive cruise assist will accelerate just be-
fore changing lanes to shorten the distance
to the vehicle driving ahead.

Setting the distance
Applies to: vehicles with adaptive cruise assist
B4M-0234
Fig. 97 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 G) or ().
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 114,
fig. 94. The display matches the functions of the
indicator lights.
When approaching a vehicle driving ahead, the
adaptive cruise assist brakes to the set speed and
then maintains the set distance. If the vehicle
driving ahead accelerates, then the adaptive
cruise assist will also accelerate up to the speed
that you have set.
The following distances can be set:
