ADAPTIVE BRAKE

ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In
addition to the braking function, ADAPTIVE
BRAKE also has the HOLD function
( Y page 207) and hill start assist

PRE-SAFE Brake is only available in vehicles
with DISTRONIC PLUS.

PRE-SAFE Brake can help you to minimize
the risk of a collision with a vehicle ahead or
reduce the effects of such a collision. If PRE-
®
SAFE Brake has detected 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.
Starting at a speed of around
4 mph (7 km/h), this function warns you if
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.

Take evasive action provided it is safe to do
so.
If the driver and front passenger have their
seat belt fastened, PRE-SAFE

Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary

You can stop PRE-SAFE
at any time by:
depressing the accelerator pedal further

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
40 mph (70 km/h), PRE-SAFE
® also detect stationary obstacles such as
stopped or parked vehicles.
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
protection measures (PRE-SAFE
activated ( Y page 54). If, at speeds over
20 mph (30 km/h), a risk of collision remains
and you do not brake, take evasive action or
significantly accelerate, automatic braking
may be performed up to the level of
emergency braking. Automatic emergency
braking is not performed until immediately
