Adaptive cruise control*

Option/accessory, for more information, see Introduction.
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 number of lines for the
selected time interval is
shown during the setting itself
and for several seconds after-
wards. Then a smaller scale
version of the symbol is
shown to the right of the dis-
play. The same symbol is also shown when
Distance Alert is activated, see page 175.
NOTE
Only use the time interval that is allowed in
accordance with local traffic regulations.
If cruise control does not seem to react to
activation the reason may be that the time
interval to the closest vehicle prevents an
increase in speed.
The higher the speed, the longer the calcu-
lated distance in metres for a specific time
interval.
Temporary deactivation - standby mode
Press the steering wheel button to tempo-
rarily disengage the cruise control and set it in
standby mode - set speed is shown in brackets
in the display, e.g.
(100) .
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
than 1 minute
1
•
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
Adaptive cruise control is dependent on other
systems e.g. stability and traction control
(DSTC). If any of these systems stop working
then cruise control is automatically deacti-
vated.
In the event of automatic deactivation a signal
will sound and the message
Cruise control
Cancelled
is shown in the display. The driver
must then intervene and adapt the speed and
distance to the vehicle ahead.
An automatic deactivation can be due to:
•
engine speed is too low/high
•
speed falls below 30 km/h
•
wheels lose traction
•
brake temperature is high
•
the radar sensor is covered e.g. by wet
snow or heavy rain (radar waves blocked).
Resume set speed
Cruise control in standby mode is re-activated
with one press on the steering wheel button
- the speed is then set to the last stored
speed.
NOTE
A significant increase in speed may arise
after the speed has been resumed with
.
Deactivate
The cruise control is switched off with the
steering wheel button
in standby mode or
with one long press in active mode. The set
speed is cleared and cannot be resumed with
the
button.
1 Disengaging and selecting a higher or lower gear does not involve standby mode.
