The ACC has certain limitations inherent to
the syst
em. Cert
ain r
eactions, under certain
circumstances, may be unexpected or come
late from the driver's point of view. So pay at-
tention in order to intervene if necessary.
The following situations require maximum at-
tention:
Starting driving after a stationary period
After a stopping phase, the ACC may begin
moving when the vehicle in front moves off
(vehicles with automatic transmission). On
vehicles with manual transmission, follow the
instructions in the instrument panel
›››
.
Overtaking
When the t
urn signal lights up bef
or
e the ve-
hicle starts to overtake, the ACC accelerates
the vehicle automatically and thus reduces
the distance from the vehicle in front.
When the vehicle moves to the overtaking
lane, if the ACC does not detect another ve-
hicle in front, it accelerates until it reaches the
programmed speed.
System acceleration can be interrupted at
any time by pressing the brake pedal or by
pressing the button 

Driving through a bend
When entering or leaving some curves, the
radar sensor may cease to sense the vehicle
driving in front of it, or react to a vehicle in the
adjacent lane
›››
Fig. 167 . The vehicle may
brake unnecessarily or stop reacting to the
vehicle in front. In this case, the driver has to
intervene by accelerating or interrupting the
braking by pressing the brake or pressing the
button 

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