Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.For more information, see “Practical hints”
(
page 566).
Adaptive Brake
Adaptive Brake provides a high level of
braking safety as well as increased braking
comfort. It is coupled with ABS, ESP
® and
BAS. Adaptive Brake takes driver and vehi-
cle characteristics into consideration, thus
achieving an optimal braking effect.
Warning!G
When the ABS is malfunctioning, the BAS,
BAS Plus* and ESP® are also switched off.
When the ABS is malfunctioning, the wheels
may lock during hard braking, reducing
steering capability and extending the brak-
ing distance.
Warning!G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded. The ABS cannot prevent acci-
dents, including those resulting from exces-
sive speed in turns, following another
vehicle too closely, or hydroplaning.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or dan-
gerous manner which could jeopardize the
user’s safety or the safety of others.

69 Safety and Security
Driving safety systems
After 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 336). 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.

Driving safety systems
PRE-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 268).
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.
iPRE-SAFE® Brake will remain passive while
DISTRONIC Plus* is switched on (

Warning!G
Some jurisdictions prohibit the driver from
using a cellular telephone while driving.
Whether or not prohibited by law, for safety
reasons, the driver should not use the cellu-
lar telephone while the vehicle is in motion.
Stop the vehicle in a safe location before
placing or answering a call.
If you nonetheless choose to use the mobile
phone
1 while driving, please use the hands-
free feature and be sure to pay attention to
the traffic situation at all times. Use the mo-
bile phone only when road, weather and traf-
fic conditions permit. Otherwise, you may
not be able to observe traffic conditions and
could endanger yourself and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approxima-
tely 14 m) every second.
1Observe all legal requirements.
Warning!G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.
