Driving safety systems
PRE-SAFE
®
Brake will only assist you by
automatically initiating braking if the driver
and front passenger have their seat belts
fastened.
Using the radar sensors, PRE-SAFE
®
Brake
detects obstacles that are in your driving
path for a sufficient period of time for the
system to recognize it. If you approach a
vehicle and PRE-SAFE
®
Brake has estab-
lished that the distance to the vehicle
ahead at your current speed is so close
that PRE-SAFE
®
Brake will not be capable
of slowing the vehicle sufficiently, the sys-
tem will initially warn you visually and
acoustically.
When travelling in Canada in a vehicle not
registered in Canada, you must switch off
the radar sensor system* (
page 282).
Canadian law does not permit the use of
the radar sensor system* (
page 282) for
vehicles from outside of Canada. When you
switch off the radar sensor system*, the
following functions are deactivated:
ț BAS Plus* ( page 69)
ț DISTRONIC Plus* ( page 424)
ț Park Assist* ( page 448)
ț PRE-SAFE
®
Brake
Always pay attention to traffic conditions
even while PRE-SAFE
®
Brake is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident resulting in person-
al or fatal injury to you or others.
