ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-

PRE-SAFE Brake is only available in vehicles

®
PRE-SAFE Brake can help you to minimise
the risk of a collision with a vehicle ahead or
reduce the effects of such a collision. If PRE-
®
SAFE Brake detects a risk of collision, you
will be warned visually and acoustically as
well as by automatic braking. PRE-SAFE
Brake cannot prevent a collision without your
intervention.
This function will issue a warning if:
at speeds of around 30 km/h or more, over
R
several seconds, the distance maintained
to the vehicle travelling in front is insuffi-
cient.
The · distance warning lamp then lights
up in the instrument cluster.
at a speed of approximately 7 km/h or
R
higher, you very quickly approach a vehicle
in front.
An intermittent warning tone will then
sound and the · distance warning lamp
will light up in the instrument cluster.
Brake immediately in order to increase the

distance from the vehicle in front.

Take evasive action provided it is safe to do

Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE
You can prevent the intervention of the PRE-

SAFE Brake at any time by:
depressing the accelerator pedal further

there is no longer an obstacle detected in

front of your vehicle.
With the help of the radar sensor system,
®
PRE-SAFE Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
At speeds up to approximately 70 km/h,PRE-
®
SAFE Brake can also detect stationary
obstacles such as stopped or parked vehi-
cles.
If you approach an obstacle and PRE-SAFE
Brake detects a risk of a collision, the system
will alert you both visually and acoustically. If
you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently. If there is an increased risk
of collision, preventative passenger protec-
tion measures (PRE-SAFE
( page 48). If, at speeds over 30 km/h, a risk
Y
of collision remains and you do not brake,
take evasive action or significantly acceler-
ate, automatic braking may be performed up
to a level of automatic emergency braking.
Automatic emergency braking is not per-
formed until immediately prior to an accident
that can no longer be avoided.
