* Option/accessory, for more information, see Introduction.
•
the gear selector is moved to N position
(automatic gearbox)
•
the driver maintains speed higher than
the stored speed for longer than
1 minute.
The driver must then regulate the speed.
A temporary increase in speed with the accel-
erator pedal, e.g. during overtaking, does not
affect the setting - the car returns to the last
stored speed when the accelerator pedal is
released.
For more information, see the sections Man-
aging speed (p. 202) and Overtaking another
vehicle (p. 204).
Automatic standby mode
The adaptive cruise control is dependent on
other systems, e.g. Stability system ESC
(p. 183). If any of these systems stops work-
ing, the adaptive cruise control is deactivated
automatically.
In the event of automatic deactivation a signal
will sound and the message
Adaptive cruise
control cancelled is shown in the combined
instrument panel. The driver must then inter-
vene and adapt the speed and distance to
the vehicle ahead.
An automatic deactivation can be due to:
•
the driver opens the door
•
the driver takes off his seatbelt
•
engine speed is too low/high
•
speed has fallen below 30 km/h
14
•
wheels lose traction
•
brake temperature is high
•
the radar sensor is covered e.g. by wet
snow or heavy rain (radar waves blocked).
For more information on symbols, messages
and their meaning, see section Symbols and
messages in the display (p. 211).
Resume set speed
Adaptive cruise control in standby mode is
reactivated with one press on the steering
wheel button
- the speed is then set to the
last stored speed.
NOTE
A marked speed increase may occur once
the speed has been resumed by selecting

Adaptive cruise control* - overtaking
another vehicle
ACC can also assist during overtaking.
When the car is following another vehicle and
the driver indicates an impending overtaking
manoeuvre with the direction indicator
15
, the
adaptive cruise control helps to briefly accel-
erate the car towards the vehicle in front.
This function is active at speeds
above 70 km/h.
Read more about the different time intervals
(p. 203) to the vehicle in front.
Read more about how you manage the speed
(p. 202).
WARNING
Be aware that this function can be acti-
vated in more situations other than during
overtaking, e.g. when a direction indicator
is used to indicate a change of lane or exit
to another road - the car will then acceler-
ate briefly.
