The adaptive cruise control (ACC) has cer-
t
ain physical limit
ations inher
ent in the sys-
tem. For example, certain reactions of the
ACC, in certain circumstances, may be unex-
pected or come late from the driver's point of
view. So pay attention in order to intervene if
necessary.
For example, the following traffic situations
call for the utmost attention:
Starting driving after a stopping phase
(only vehicles with automatic gearbox)
After a stopping phase, the ACC may begin
driving automatically when the vehicle in
front drives off

.
Overtaking
When the t
urn signal lights up bef
or
e the ve-
hicle begins an overtaking manoeuvre, the
ACC accelerates the vehicle automatically
and thus reduces the distance from the vehi-
cle in front.
When the vehicle enters the overtaking lane,
if the ACC does not detect another vehicle in
front, it accelerates until it reaches the pro-
grammed speed and maintains it.
System acceleration can be interrupted at
any time by pressing the brake or moving the
third lever backwards

Driving through a bend
On entering or exiting bends, the radar sensor
may stop detecting the vehicle in front or re-
acting to a vehicle in the adjacent lane
›››
Fig. 275 A In these situations the vehicle
may brake unnecessarily or fail to react to
the vehicle in front. In this case, the driver has
to intervene by accelerating or interrupting
the braking process by applying the brake or
pushing the third lever backwards

Driving in tunnels
When driving through tunnels the radar sen-
sor may be limited. Switch off the ACC in tun-
nels.
