Safety and Security
Driving safety systems
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.
®
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
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.
