Adaptive cruise control*
NOTE
If any of the Cruise Control buttons are
held depressed for several minutes then it
is blocked and deactivated. To be able to
reactivate Cruise Control, the car must be
stopped and the engine restarted.
In certain situations, cruise control cannot
be activated. In this case, the combined
instrument panel shows
Unavailable
, see page 169.

Set time interval
Different time intervals to the
vehicle in front can be
selected and shown in the
combined instrument panel
as 1-5 horizontal lines - the
more lines the longer the
time interval. One line corre-
sponds to approximately 1 second to the
vehicle in front, 5 lines
approximately 3 seconds.
To set/change the time interval:
•
Increase or decrease with the steering
wheel buttons /
At low speed, when the distances are short,
the adaptive cruise control increases the time
interval slightly.
Disengaging and selecting a higher or lower gear does not involve standby mode.

Option/accessory, for more information, see Introduction.
The adaptive cruise control allows the time
interval to vary noticeably in certain situations
in order to allow the car to follow the vehicle
in front smoothly and comfortably.
Note that a short time interval only allows the
driver a short time to react and take action if
any unforeseen traffic problem should arise.
The same symbol is also shown when Dis-
Cruise control
tance Warning is activated, see page 172.
Only use the time intervals permitted by
local traffic regulations.
If Cruise Control does not appear to react
when activated, this may be because the
time distance to the car in front is prevent-
ing an increase in speed.
The higher the speed the longer the calcu-
lated distance in metres for a given time
interval.
Temporary deactivation - standby mode
To temporarily disengage the adaptive cruise
control and set it in standby mode:
.
•
Press the steering wheel button
NOTE
This symbol and the stored speed's
marking then change colour from
GREEN to WHITE.
Standby mode due to driver intervention
Cruise control is temporarily disengaged and
set in standby mode if:
•
the foot brake is used
•
the clutch pedal is depressed for longer
3
than 1 minute
•
the gear selector is moved to N position
(automatic gearbox)
•
the driver maintains a speed higher than
the set 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 cruise control setting - the car
returns to the last stored speed when the
accelerator pedal is released.
Automatic standby mode
The adaptive cruise control is dependent on
other systems, such as DSTC (see page 154).
If any of these systems stop working then
cruise control is automatically deactivated.
In the event of automatic deactivation a signal
will sound and the message
Cancelled
is shown in the combined instru-
.
ment panel. The driver must then intervene
and adapt the speed and distance to the
vehicle ahead.
