– Setting the ACC
– Troubleshooting
The Adaptive Cruise Control (ACC) main-
tains a constant speed that you have set.
If the vehicle approaches a vehicle in
front, the ACC automatically adapts the
speed so that a distance you have selec-
ted is maintained.
.
You can set a speed between around 30 km/h
and around150 km/h. Depending on equipment
level, there may be slight deviations in the speed
range.
Driving with ACC
You can override the active ACC system at any
time. Control will be stopped if you brake. If you
accelerate, control will be interrupted while you
are accelerating and then resumed with the set
speed.
Whether the vehicle is equipped with ACC
The vehicle is equipped with ACC if you can ad-
just settings for ACC in the instrument cluster
menu
page 114.

Driver intervention prompt
The red warning lamp on the instrument
cluster lights up and an acoustic warning is
given. As automatic deceleration by the
ACC system is not sufficient or the system
limits have been reached, the ACC system
will request you to take over control of the
vehicle and be prepared to brake.
Radar sensor
ACC detects driving situations by means of the
radar sensors in the front of the vehicle

The range of the radar sensor is up to approxi-
mately 160 m.
WARNING
The adaptive cruise control system (ACC) can-
not replace the driver's attention and operates
only within the limits of the system. Improper
or careless use of ACC can easily lead to acci-

dents and serious injuries. If you do not pay due
attention, there is a risk of accidents and seri-
115
ous or even fatal injuries.
● Adapt your speed and distance from the ve-
hicles ahead to suit visibility, weather, road,
and traffic conditions.
● For safety reasons, never use ACC in low visi-
bility conditions, on roads with multiple
curves, inclines, or slippery surfaces (such as
snowy, wet, or flooded roads).
● Never use ACC during off-road driving or on
unpaved roads. ACC can only be used on
paved roads.
● Depending on vehicle equipment, ACC may
not respond to stationary vehicles.
● ACC will not react to persons, animals, or ve-
hicles that are crossing laterally or approach-
ing the vehicle in the same lane.
● If sufficient deceleration is not possible
through ACC, the driver shall immediately
apply foot brake as required by the system.
● Foot brake should be applied as soon as
braking requirement information is displayed
on the instrument cluster display.
● If the system requests the driver to take con-
trol of the vehicle and the vehicle continues
to move, the driver must apply the foot
brake.
● Always be prepared to take control of the ve-
hicle by accelerating or braking yourself.
WARNING
Never take risks by using the additional con-
venience features provided by the adaptive
cruise control (ACC). ACC cannot detect all driv-
ing situations and may not react or may react
with a delay or in an undesired way. Drivers are
responsible for all driving behaviors at all times.
● Pay attention to changes in road conditions
and drive with caution when using the ACC.
Failure to do so may lead to accidents and
serious or fatal injuries.
● The ACC can only work within its maximum
range when the radar sensors detect a vehi-
cle in front. Under special circumstances, the
system may not issue a warning or intervene
immediately or may issue a warning or inter-
vene with a delay. In this case, you should
use the brakes and take control of the vehi-
cle as needed to avoid accidents and serious
or fatal injuries.
