PRE-SAFE ®
system
GWarning
The PRE-SAFE ®
system reduces the impact of
an accident on vehicle occupants, as long as
their seat belts have been fastened correctly.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out. You
should therefore always drive carefully and
adapt your driving style to the prevailing road,
weather and traffic conditions.
PRE-SAFE ®
takes pre-emptive measures to
protect the occupants in certain hazardous
situations.
PRE-SAFE ®
intervenes:
R in emergency braking situations, e.g. if BAS
is activated or, on vehicles with DISTRONIC
PLUS, if BAS PLUS or PRE-SAFE ®
Brake
intervenes powerfully
R if the radar sensor system detects an
imminent danger of collision in certain
situations (on vehicles with DISTRONIC
PLUS)
R in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely
or when having to swerve to avoid an
obstacle at a speed above 85 mph
(140 km/h).
PRE-SAFE ®
takes the following measures
depending on the hazardous situation
detected:
R the front seat belts are pre-tensioned.
R under accident conditions, the front-
passenger seat is adjusted if it is in an
unfavorable position.
R increases the air pressure in the side
bolsters of the seat cushion and seat
backrest of the multicontour seats in the
front.
R Coupe: if the vehicle skids, the panorama
sliding sunroof and the front side windows
are closed so that only a small gap remains.
R Cabriolet: if the vehicle skids, the front side
windows are closed so that only a small gap
remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat is
reduced again. All settings made by PRE-
SAFE ®
can then be reversed.
If the seat belts are not released:XWhen the vehicle is stationary, move the
backrest or seat back slightly.
The belt pretensioning is reduced and the
locking mechanism is released.GWarning
Make sure that nobody can become trapped
as you adjust the seat.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
More information about belt adjustment, a
convenience function integrated into PRE-
SAFE ®
, can be found in the "Belt adjustment"
section ( Y page 56).
NECK-PRO head restraints
The NECK-PRO head restraints increase
protection for the driver's and front-
passenger's head and neck. In the event of a
rear collision of a certain severity, the NECK-
PRO head restraints on the driver's and front-
passenger seats are moved forwards and
upwards. This provides better head support.
GWarning
Do not secure any objects (e.g. coat hangers)
on the NECK-PRO head restraints. Otherwise,
Occupant safety51SafetyBA 207 USA, CA Edition B 2011; 1; 3, en-USd2sboikeVersion: 3.0.3.62010-05-20T10:38:09+02:00 - Seite 51Z

GWarning
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
ABS works from a speed of about
5 mph (8 km/h) upwards, regardless of road-
surface conditions. ABS works on slippery
surfaces, even when you only brake gently.
The ! warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Braking
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
XIf ABS intervenes: continue to depress the
brake pedal with force until the braking
situation is over.XTo make a full brake application:
depress the brake pedal with full force.GWarning
If the ABS malfunctions, other driving systems
such as the BAS or the ESP ®
are also switched
off. Observe indicator and warning lamps that
may come on as well as messages in the
multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing the steering
capability and extending the braking distance.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
BAS (Brake Assist)GWarning
Observe "Important safety notes"
( Y page 64).
BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
XKeep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
GWarning
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.
BAS PLUS (Brake Assist PLUS)
GWarning
Observe "Important safety notes"
( Y page 64).
At speeds above approximately
20 mph (30 km/h), BAS PLUS assists you
when braking in hazardous situations and
uses the radar sensor system to evaluate the
traffic conditions.
GWarning!
BAS PLUS is a convenience system designed
to assist the driver during vehicle operation.
The responsibility for the vehicle speed and
the distance to the vehicle ahead, including
most importantly brake operation to assure
safe stopping distance, always remains with
the driver.
Always pay attention to traffic conditions
even while BAS PLUS is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
Driving safety systems65SafetyBA 207 USA, CA Edition B 2011; 1; 3, en-USd2sboikeVersion: 3.0.3.62010-05-20T10:38:09+02:00 - Seite 65Z

could cause an accident. Personal or fatal
injury to you or others may be the result.
i This equipment has been approved by the
FCC as a "Vehicular Radar System". The
radar sensor system is intended for use in
an automotive radar system only. Removal,
tampering, or altering of the device will void
any warranties, and is not permitted by the
FCC. Do not tamper with the device in any
way.
Any unauthorized modification to this
device could void the user's authority to
operate the equipment.
BAS PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time. Should you approach a detected
obstacle quickly, BAS PLUS calculates the
braking force necessary to avoid a rear-end
collision. Should you additionally apply the
brakes, BAS PLUS will automatically increase
the braking force to a level suitable for the
traffic conditions.
If BAS PLUS demands particularly high
braking force, PRE-SAFE ®
is activated
simultaneously.XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again when:
R you release the brake pedal
R no obstacle is detected in front of your
vehicle
R there is no longer any danger of a rear-end
collision
BAS PLUS is then deactivated.
At speeds up to approximately
40 mph (70 km/h), BAS PLUS can also detect
stationary obstacles, for example, stopped or
parked vehicles.
For BAS PLUS to assist you when driving, the
radar sensor system must be switched on and
operational. You can check this by activating
DISTRONIC PLUS ( Y page 174) or via the
"radar sensor" function in the on-board
computer( Y page 211).GWarning!
BAS PLUS will only respond with brake
assistance if it has clearly detected an object.
Detection can be impeded by
R dirty or covered sensors
R snowfall or heavy rain
R disturbance from other radar sources
R strong radar reflection such as in parking
garages
BAS PLUS uses radar signals that are not
reflected well by narrow objects and
absorptive materials. For this reason BAS
PLUS will not react to persons, animals, and
approaching traffic or cross-traffic.
BAS PLUS may not detect narrow vehicles
driving in front of you, such as motorcycles
and vehicles driving offset from your vehicle
center.
Following a collision or accident-related
damage to the front end of the vehicle, have
the configuration and operation of the radar
sensors checked at an authorized Mercedes-
Benz Center.
If BAS PLUS is not available due to a
malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.

GWarning
Observe "Important safety notes"
( Y page 64).
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®

Immediately brake your vehicle to increase
the distance between your vehicle and the
vehicle driving in front of you. The warning
sound is intended as a final caution that you
have not interceded with your own braking
inputs to avoid a potentially dangerous
situation. Do not wait for the operation of the
warning signal to intercede with your own
braking, as that will result in potentially
dangerous emergency braking which will not
always result in an impact being avoided.
Tailgating increases the risk of an accident.GWarning!

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. If you approach an obstacle
and PRE-SAFE ®
Brake detects a risk of a
collision, the system will initially alert you
both visually and acoustically. If you do not
brake or steer, the vehicle will at first
automatically brake slightly. In the event of
an increased risk of a collision, PRE-SAFE ®
is
activated ( Y page 51). If the risk of collision
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking.GWarning!
The PRE-SAFE ®
Brake will only respond with
brake assistance if it has clearly detected an
object. Detection can be impeded by:
R dirty or covered sensors
R snowfall or heavy rain

Driving safety systems69SafetyBA 207 USA, CA Edition B 2011; 1; 3, en-USd2sboikeVersion: 3.0.3.62010-05-20T10:38:09+02:00 - Seite 69Z

GWarning
Depending on the vehicle speed, PRE-SAFE®
Brake brakes your vehicle with a maximum of
13 ft/s 2
(4 m/s 2
) before a possible hard stop.
This corresponds to about 40 % of the
maximum deceleration ability of your vehicle.
The driver must apply the brakes additionally
in order to prevent a collision. The self-acting
hard stop will be initiated when the imminent
danger of a collision exists, e.g. when an
evasive maneuver cannot avoid an accident.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.
At speeds up to approximately
40 mph (70 km/h), PRE-SAFE ®
Brake can
also detect stationary obstacles, for example
stopped or parked vehicles.
GWarning!
If you do not receive visual or acoustic
warning signals, the PRE-SAFE ®
Brake may
R not have recognized the collision risk
R have been deactivated
R be malfunctioning
Apply the brakes yourself to avoid a collision.
XTo activate: activate PRE-SAFE ®
Brake in
the on-board computer ( Y page 207).
The Ä symbol appears in the lower
multifunction display, as long as the HOLD
function is not activated ( Y page 184).
On vehicles with parking guidance, the P
gear must be engaged for the icon to be
displayed.
For PRE-SAFE ®
Brake to assist you when
driving, the radar sensor system must be
switched on and operational.
PRE-SAFE ®
Brake does not always detect
complex traffic situations properly. You can
terminate the braking action of PRE-SAFE ®
Brake in a non-critical driving situation at any
time if:
R an acoustic and visual warning occurs
R the vehicle brakes
To end this, 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 you drive slower than approximately
9 mph (15 km/h)
R there is no longer an obstacle detected in
front of your vehicle
R there is no longer any danger of a collision
Following a collision or accident-related
damage to the front end of the vehicle, have
the configuration and operation of the radar
sensors checked. Choose a qualified
specialist workshop for this which has the
necessary specialist knowledge and tools for
the work required. Mercedes-Benz
recommends that you use an authorized
Mercedes-Benz Center for this purpose.

DISTRONIC PLUS
Important safety notes
DISTRONIC PLUS regulates the vehicle's
speed and automatically helps you maintain
the distance to the vehicle detected in front.
It brakes automatically in order to avoid
exceeding the set speed.
On long and steep downhill gradients,
especially if the vehicle is laden, you must
select shift range 1, 2 or 3 in good time. By
doing so, you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly.
If a slower-moving vehicle is detected in front,
DISTRONIC PLUS causes your vehicle to
brake and maintain a preset distance to the
vehicle in front.
GWarning!
The DISTRONIC PLUS requires familiarity with
its operational characteristics. We strongly
recommend that you review the following
information carefully before operating the
system.
GWarning!
The DISTRONIC PLUS is a convenience
system. Its speed adjustment reduction
capability is intended to make cruise control
more effective and usable when traffic speeds
vary. It is not however, intended to, nor does
it, replace the need for extreme care.
The responsibility for the vehicle's speed,
distance to the preceding vehicle and, most
importantly, brake operation to ensure a safe
stopping distance, always remains with the
driver.
The DISTRONIC PLUS cannot take street and
traffic conditions into account.
Complex driving situations are not always
fully recognized by the DISTRONIC PLUS. This
could result in wrong or missing distance
warnings.
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
( Y page 211) and operational.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
20 mph (Canada: 30 km/h) and
120 mph (Canada: 200 km/h). If there is a
vehicle in front, DISTRONIC PLUS is
operational in the speed range between
0 mph (Canada: 0 km/h) and
120 mph (Canada: 200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS emits radar waves, it can
simulate radar detectors used by police
authorities. You can refer to the applicable
section in the Operator's Manual if there are
any questions concerning this.

warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.GWarning!
The DISTRONIC PLUS adaptive cruise control
is not a substitute for active driving
involvement. It does not react to pedestrians
or on stationary objects, nor does it recognize
or predict the curvature and lane layout or the
movement of preceding vehicles. The
DISTRONIC PLUS can only apply a maximum
of 40% of the vehicle's braking power.
The DISTRONIC PLUS may not detect narrow
vehicles possibly driving in front of you, such
as motorcycles and vehicles driving in an
offset formation.
