70 Safety and SecurityDriving safety systemsAfter a hard collision or damage to the
front of the vehicle from an accident, have
the adjustment and operation of the radar
sensors checked by an authorized
Mercedes-Benz Center.
If BAS Plus is not available due to a radar
sensor malfunction, the braking system
will continue to function normally with full
brake boost and full standard BAS
function.
EBP
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allow-
ing the rear brakes to supply a greater pro-
portion of the braking effort in straight line
braking without a loss of vehicle stability.
ESP
®
The Electronic Stability Program (ESP
®) is
operational as soon as the engine is run-
ning and monitors the vehicle’s traction
(force of adhesive friction between the
tires and the road surface) and handling.
The ESP
® recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting the engine output, the ESP
®
works to stabilize the vehicle. The ESP® is
especially useful while driving off and on
wet or slippery road surfaces. The ESP®
also stabilizes the vehicle during braking
and steering maneuvers.
The ESP
® warning lamp v in the instru-
ment cluster flashes when the ESP
® is en-
gaged.
The ESP
® warning lamp v in the instru-
ment cluster comes on when you switch on
the ignition (
page 365). It goes out when
the engine is running.
Warning!
G
When the EBP is malfunctioning, the ABS,
BAS, BAS Plus* and ESP
® are also switched
off.
If the EBP is malfunctioning, the brake sys-
tem will still function with full brake boost.
However, the rear wheels could lock up dur-
ing emergency braking situations, for exam-
ple. You could lose control of the vehicle and
cause an accident. Adapt your driving style
to the changed driving characteristics.
78 Safety and SecurityDriving safety systemsPRE-SAFE
® Brake can react to stationary
obstacles such as standing or parked vehi-
c le s a t roa d s pe eds of up to ap proxim a tel y
40 mph (70 km/h).
Activating and deactivating: Activate
or deactivate PRE-SAFE
® Brake using
the instrument cluster control system
(
page 298).
After the function has been activated,
indicator : appears on the
left-hand side of the multifunction dis-
play.PRE-SAFE
® Brake does not always clearly
interpret complex traffic situations. If a vi-
sual and/or acoustic warning is issued in
an uncritical driving situation, or if the ve-
hicle brakes lightly, you can interrupt the
PRE-SAFE® Brake maneuver by
pressing down all the way on the accel-
erator or using kickdown
releasing the brake pedal
The PRE-SAFE
® Brake maneuver is termi-
nated immediately when
you avoid the obstacle by evasive
steering
you drive less than 9 mph (15 km/h)
an obstacle can no longer be identified
ahead of you
the system no longer senses the risk of
a collisionAfter a hard collision or damage to the
front of the vehicle from an accident, have
the settings and operation of the radar
sensors checked by an authorized
Mercedes-Benz Center.
Warning!
G
If you do not receive visual or acoustic warn-
ing signals, PRE-SAFE
® Brake has either not
recognized the collision risk, has been deac-
tivated or is malfunctioning. Apply the
brakes yourself to avoid a collision.
i
PRE-SAFE
® Brake will remain passive while
DISTRONIC Plus* is switched on (
