Z\ WARNING
It is dangerous to activate cruise control and

Setting the distance
Applies to: vehicles with Audi adaptive cruise control



B4M-0234


Fig. 117 Operating lever: setting the distance
> Tap the switch to display the distance that is
currently set > fig. 117.
> To increase or reduce the distance in incre-
ments, tap the switch upward/downward again.
The distance between the two vehicles will
change in the instrument cluster display.
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 also acceler-
ate up to the speed that you have set.
The higher the speed, the greater the distance
=> A\. The Distance 3 setting is recommended.
That is equal to the general recommendation of
“half the speed shown on the speedometer”.
The distances provided are specified values. De-
pending on the driving situation and how the ve-
hicle ahead is driving, the actual distance may be
more or less than these target distances.
If you change the time gaps, the value you have
just set appears briefly in the instrument cluster
display, for example [Eg for Distance 3. This only
occurs if the adaptive cruise control is not cur-
rently shown in the display > page 120, fig. 113.
Distance 1: this setting corresponds to a distance
of 92 feet (28 m) when traveling at 62 mph (100
km/h), or a time distance of 1 second.
Distance 2: this setting corresponds to a distance
of 118 feet (36 m) when traveling at 62 mph
(100 km/h), or a time distance of 1.3 seconds.
Distance 3: this setting corresponds to a distance
of 164 feet (SO m) when traveling at 62 mph
(100 km/h), or a time distance of 1.8 seconds.
Distance 4: this setting corresponds to a distance
of 219 feet (67 m) when traveling at 62 mph
(100 km/h), or a time distance of 2.4 seconds.
Distance 5: this setting corresponds to a distance
of 328 feet (100 m) when traveling at 62 mph
(100 km/h), or a time distance of 3.6 seconds.

When setting the distance, the driver is re-
sponsible for adhering to any applicable legal
regulations.

play
Activating rear cross-traffic assist
The rear cross-traffic assist is activated automati-
cally if you turn on the parking aid > page 136 or
shift into reverse gear.
The rear cross-traffic assist can warn the driver of
a potential collision with approaching cross-traf-
fic when driving in reverse at speeds up to ap-
proximately 7 mph (12 km/h). Within its limits,
the system monitors the areas behind and next
to the vehicle using the radar sensors when leav-
ing a parking space > page 132, fig. 127. Moving
objects that are approaching, such as cars, are
detected > fig. 128.
If the system detects critical cross traffic when
backing out of a parking space, it will react as fol-
lows:
134
— Visual indicator: an indicator appears in the In-
fotainment system display with a red arrow
symbol. The arrow points in the direction from
which the object is approaching > fig. 129.
— Audible warning signal: a continuous tone may
sound as an additional indicator when driving in
reverse.
— Automatic brake activation: a brief activation
of the brakes may also warn you of a potential
collision with an approaching object.
The audible warning signal and the automatic
brake activation occur only when driving in re-
verse.

iN WARNING
—The rear cross-traffic assist is an assist sys-
tem and cannot prevent a collision by itself.
The driver must always intervene. The driver
is always responsible for braking at the cor-
rect
time.
— Please note that the rear cross-traffic assist
may activate the brakes unexpectedly. Se-
cure any cargo that you are transporting to
reduce the risk of damage or injury.
— An additional brake activation may be trig-
gered within 10 seconds after an automatic
brake activation.
—If there is an acoustic warning signal from
the rear cross-traffic assist, then the parking
system may not warn you of detected obsta-
cles under certain circumstances.
— The view of the radar sensors may be im-
paired by leaves, snow, heavy spray or dirt.
Clean the area in front of the sensors
=> page 132, fig. 127.

ZA WARNING
— The rear cross-traffic assist will not provide
alerts about people and cannot warn you
about every type of approaching objects,
such as cyclists. Always monitor the traffic
as well as the vehicle's surroundings with di-
rect eye contact.
— The rear cross-traffic assist will not provide
alerts if your vehicle is parallel or diagonally
