adaptive cruise control (ACC) 139
Controls Safety Driving tips General maintenance Self-help Technical data
• An acoustic warning will also sound (unless it has been deacti-
vated in the sound system or MMI* settings).
Note
• Pressing the brake pedal will switch off the adaptive cruise
control system. The speed set at that point will, however, remain
stored until the adaptive cruise control is activated again.
• To resume the programmed cruising speed, release the brake
pedal and pull the control lever towards you ⇒ page 132,
“Switching off the system (with speed memory function) and reacti-
vating it”.
• If you exceed the target speed by pressing the accelerator, the
driver intervention prompt will not be accompanied by a warning
tone. The indicator lamp shown in the display will also switch off
when the target speed is exceeded.
• If the adaptive cruise control triggers a braking operation the
hydraulic brake system is under pressure. This is why brake pedal
travel will be shorter and the pedal will feel “harder”.
Applies to vehicles: with adaptive cruise control
Setting the warning tone volume and driving
program
You can change the adaptive cruise control settings on
the sound system or MMI* to suit your individual driving
style.
– Select: Function selector button > adaptive cruise
control.
Setting the volume of the warning tone
If the adaptive cruise control system switches off (e.g. when the ESP
intervenes) or a driver intervention prompt appears, a warning tone
will sound.
You can set the volume of the warning tone to low, medium, or high.
The new volume will sound briefly after making any adjustment. If
you do not want a tone to sound, select off.
Adjusting the basic settings
You can set the distance (time interval) you want the adaptive cruise
control system to keep to the vehicle in front by selecting distance
1, distance 2, distance 3 or distance 4.
