Emergency Assist
How it works
Emergency Assist can detect whether the
driver is inactive and can automatically keep
the car in its lane and stop it altogether if nec-
essary. This way the system can actively help
avoid an accident or reduce its consequences.
Emergency Assist uses the same sensors as
Adaptive Cruise Control (ACC) and Lane As-
sist Therefore, carefully read the information
about the ACC ›››page174 and Lane Assist
›››page185 and take into account the limita-
tions of the systems and the indications given
in the information.
Emergency assist always available after the ig-
nition has been switched on and is activated if
the following conditions are met:
●
Travel Assist or Lane Assist) is switched on.
●
The system has detected at least one lane
boundary to the left or right of the vehicle.
Driver intervention prompt
If the emergency assist detects that the driver
is not actively doing anything, he or she is
prompted to take control of the vehicle by
audio warnings and a brief application of the
brake. In addition, a warning is shown on the
instrument cluster display and the volume of
the infotainment system is lowered.
Depending on the equipment, the driver’s seat
belt is tightened at the same time.
System intervention
If the driver does not react, the system can
brake the vehicle and keep it in its lane. The
following control lamp lights up on the instru-
ment cluster display:
The system is regulating, lane guidance
is activated.
The system is regulating, passive lane
guidance.
You can cancel the adjustment at any time by
moving the steering wheel, over-accelerating
or braking.
While the emergency assistant is in operation,
other road users are warned as follows:
●
The hazard warning lights are switched on
soon after.
●
The horn sounds (depending on the speed).
The following happens as soon as the vehicle
stops:
●
The electronic parking brake is activated.
●
All doors are unlocked.
●
The passenger compartment lighting comes
on.
●
Depending on the features, an emergency
call (eCall) is made.
Note
If the emergency assist is faulty, it may switch
o automatically.
Note
If Lane Assist is unavailable, Emergency Assist
is also unavailable.
