PRE-SAFE ® PLUS (anticipatory occu-

Introduction
PRE-SAFE ® PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE
®
PLUS is able to detect that a head-on or rear-end
collision is imminent. In certain hazardous sit-
uations, PRE-SAFE ® PLUS takes pre-emptive
measures to protect the vehicle occupants.
Important safety notes
The intervention of PRE-SAFE
®
PLUS cannot
prevent an imminent collision.
The driver is not warned before the intervention
of PRE-SAFE
®
PLUS.
PRE-SAFE ® PLUS does not intervene:
R
if the vehicle is reversing
R
when the vehicle is towing a trailer and there
is a risk of a rear-end collision
When driving, or when parking or exiting a park-
ing space with assistance from Active Parking
Assist, PRE-SAFE
®
PLUS will not apply the
brakes.
