Mercedes-Benz CLS-Class 2012 Owners Manual - Manual (Page 69)

EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section ( Y page 61).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.
G WARNING
If EBD has malfunctioned, the braking system
remains available with full brake boosting
effect. However, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident. You should therefore adapt your
driving style to the different handling
characteristics.
X Observe the notes on warning and indicator
lamps (
Y page 244) as well as display
messages ( Y page 218).
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 166) and hill start assist
( Y page 135). For further information, see
Driving tips ( Y page 152).
PRE-SAFE ® Brake
PRE-SAFE ® Brake is only available in vehicles
with DISTRONIC PLUS.
i Observe the "Important safety notes"
section ( Y page 61).
PRE-SAFE ® Brake can help you to minimize
the risk of a frontal 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.
At speeds above approximately
4 mph (7 km/h), this function warns you
when you are rapidly approaching the vehicle
in front. An intermittent warning tone will
then sound and the · distance warning
lamp in the instrument cluster will light up.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
If the driver and front passenger have their
seat belt fastened, PRE-SAFE
® Brake can also
brake the vehicle automatically at speeds
from approximately 4 mph (7 km/h) to
approximately 124 mph (200 km/h).
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE
® Brake. To stop the
braking action, you can either depress the
accelerator pedal further, activate kickdown
or release the brake pedal.
The braking action of PRE-SAFE
® Brake is
ended automatically if:
R
you maneuver to avoid the obstacle.
R
there is no longer any danger of a rear-end
collision.
R
there is no longer an obstacle detected in
front of your vehicle.
