Warning!
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
could cause an accident. Personal or fatal
injury to you or others may be the result.
i This device

has been approved by the FCC
as a “Vehicular Radar System”. The radar
sensor 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, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
BAS PLUS detects obstacles that are in your
driving path for a sufficient period of time to
permit the system to recognize these
obstacles. If you approach the detected
obstacle quickly, BAS PLUS calculates the
level of brake power boost appropriate for the circumstance to supply when the driver
applies the brakes.
When you step quickly on the brake pedal in
an emergency braking situation, BAS PLUS
automatically regulates the brake power
boost to a level that is suitable for the traffic
situation.
If BAS

PLUS requires a particularly high brake
power boost, PRE-SAFE ®
is activated at the
same time.
X Keep constant pressure on the brake pedal
until the emergency braking situation is
over.
During this process, the ABS prevents the
wheels from locking up.
The brakes will resume normal operation
after
R the brake pedal is released
R no obstacles are detected in your path
R the system no longer senses a risk of a
collision
BAS PLUS is then deactivated.
BAS PLUS can react to stationary obstacles
such as standing or parked vehicles at road
speeds of up to approximately 40 mph
(70 km/h ).
BAS

PLUS can only assist you when the radar
sensors are switched on and functional. You
can check whether the sensors are active by
switching on DISTRONIC PLUS
(Y page 304) or using the Radar sensors
function ( Y page 216) in the instrument
cluster control system. G
Warning!
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 58

i USA only:
This device
has been approved by the FCC
as a “Vehicular Radar System”. The radar
sensor 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

any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
i Canada only:
This device complies with RSS-210 of
Industry Canada. Operation is subject to
the following two conditions:
1. This device may not cause interference, and
2. this device must accept any interference received, including
interference that may cause undesired
operation of the device.
Removal, tampering, or altering of the
device will void any warranties, and is not

Using the radar sensors, the PRE-SAFE ®
Brake detects obstacles that are in your
driving path for a sufficient period of time for
the system to recognize it. If you approach a
vehicle and the PRE-SAFE ®
Brake has
established that the distance to the vehicle
ahead at your current speed is so close that
the PRE-SAFE ®
Brake will not be capable of slowing the vehicle sufficiently, the system
will
initially
warn you visually and acoustically.
If you do not apply the brakes yourself or
maneuver around a sensed obstacle, the
vehicle will brake lightly automatically. The
PRE-SAFE ®
system (Y page 49) is activated
when the distance to the vehicle ahead at
your current speed is so close that the PRE-
SAFE ®
Brake will not be capable of slowing
the vehicle sufficiently. G
Warning!
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
R disturbance from other radar sources
R strong radar reflection such as in parking
garages
The PRE-SAFE ®
Brake

uses radar signals that
are not reflected well by narrow objects and
absorptive materials. For this reason the PRE-
SAFE ®
Brake will not react to persons,
animals, and approaching traffic or cross-
traffic.
The PRE-SAFE ®
Brake may not detect narrow
vehicles driving in front of you, such as
motorcycles and vehicles driving offset from
your vehicle center. G
Warning!
The PRE-SAFE ®
Brake brakes your vehicle
with a maximum of 13 ft/s 2
(4 m/s 2
). This
corresponds to about 40% of the maximum
deceleration ability of your vehicle. This
automatic braking is intended only to initiate
the braking

if the driver has not already done
so. The driver must apply the brakes in order
to prevent a collision.
The PRE-SAFE ®
Brake applies the brake pedal
automatically which results in the brake pedal
moving. Therefore keep driver’s foot area
clear at all times, including the area under the Driving safety systems

brake pedal. Objects stored in this area may
impair
pedal
movement which could interfere
with the braking ability of the PRE-SAFE ®
Brake.
Do not place your foot under the brake pedal
– your foot could become caught.
To maintain the proper distance to the vehicle
in front of you and thus prevent a rear-end
collision, you must apply the brakes yourself.
X Brake the vehicle immediately to avoid a
collision.
Under no circumstances should the driver
await the intermittent warning sound
before braking. Observe the following
warning note.
The intermittent

warning sound ceases and
the distance warning lamp · goes out
when the necessary distance to the vehicle
ahead is again established.
The PRE-SAFE ®
Brake
can react to stationary
obstacles such as standing or parked vehicles
at road speeds of up to approximately 40 mph
(70 km/h). G
Warning!
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.
The PRE-SAFE ®
Brake does not always clearly
interpret complex traffic situations. If a visual
and/or acoustic warning is issued in an
uncritical driving situation, or if the vehicle
brakes lightly, you can interrupt the PRE-
SAFE ®
Brake maneuver by pressing down all
the way on the accelerator pedal, using
kickdown, or releasing the brake pedal. The PRE-SAFE
®
Brake maneuver is
terminated immediately when
R you avoid the obstacle by evasive steering
R you drive less than 9 mph (15 km/h

)
R an obstacle can no longer be identified
ahead of you
R the system no longer senses the risk of a
collision
i The PRE-SAFE ®
Brake will remain passive
while DISTRONIC PLUS is switched on
(Y page 304).
After 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.
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 216). Canadian
law does not permit the use of the radar
sensor system for vehicles from outside of
Canada.
When you switch off the radar system, the
following functions are deactivated:
R PRE-SAFE ®
Brake
R BAS PLUS (Y page 57)
R DISTRONIC PLUS (Y page 304)
R Park Assist ( Y page 324)

X Activating and deactivating: Activate or
deactivate the PRE-SAFE ®
Brake using the
instrument cluster control system
(Y page 213).
After the function has been activated, the
PRE-SAFE ®
Brake indicator Ä appears
in the instrument cluster. When the HOLD
function is switched on, the PRE-SAFE ®
Brake indicator Ä will not appear. 64

Warning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between or
under the pedals. You could then no longer
brake or accelerate. This could lead to
accidents and injury. G
Warning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly. Starting the engine
