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

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.XKeep 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 330) or using the Radar sensors
function ( Y page 236) in the instrument
cluster control system.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.
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.

braking safety as well as increased braking
comfort. Adaptive Brake takes driver and

PRE-SAFE ®
Brake
The PRE-SAFE ®
Brake is available in vehicles
equipped with DISTRONIC PLUS. The PRE-
SAFE ®
Brake can assist you in minimizing the
risk of a rear-end collision with a vehicle in
front of you. The PRE-SAFE ®
Brake may also
reduce the severity of an accident. At speeds
above approximately 20 mph (30 km/h) it will
issue a warning when your vehicle is
approaching the preceding vehicle very
quickly. An intermittent acoustic warning
sounds and the distance warning lamp 00BA
in the instrument cluster comes on.
When the driver and front passenger have
fastened their seat belts, the PRE-SAFE ®
Brake can also
R brake the vehicle within a speed range of
up to 112 mph (180 km/h) automatically
R activate preventative occupant safety
measures (PRE-SAFE ®
) ( Y page 54)
GWarning!
An intermittent warning sounds and the
distance warning lamp 00BA in the instrument
cluster is illuminated if the PRE-SAFE ®
Brake
calculates that the distance to the vehicle
ahead and your vehicle’s current speed
indicate that the PRE-SAFE ®
Brake will not be
capable of slowing the vehicle sufficiently to
maintain the preset following distance, which
creates a danger of a collision.
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!
The PRE-SAFE ®
Brake 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 the PRE-SAFE ®
Brake is switched
on. Otherwise, you may not be able to
recognize dangerous situations until it is too
late and could cause an accident resulting in
personal or fatal injury to you or others.

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

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 54) 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.
When the danger of a collision still persists
and you do not brake or accelerate
significantly, the PRE-SAFE ®
Brake may
initiate full application of the brakes
automatically.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
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.
GWarning!
Depending on the vehicle speed, the
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 driving maneuver cannot
avoid an accident.
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
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.XBrake 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 00BA 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).
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.
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 330).
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

Voice Control System introduction
Safety notes
GWarning!
Only use the Voice Control System when road
and traffic conditions permit you to do so.
Otherwise you could be involved in an
accident in which you or others could be
injured.
GWarning!
Please devote your attention first and
foremost to the traffic situation you are in.
While the system permits hands-free phone
operation, attention to traffic may be diverted
not only by physical operation of a phone, but
also by the distraction of a phone
conversation while driving. As such, for safety
reasons, we encourage the driver to stop the
vehicle in a safe place before answering or
placing a phone call.
For safety reasons, you should only select a
destination when the vehicle is stationary.
While the navigation system provides
directional assistance, the driver must remain
focused on safe driving behavior, especially
attention to traffic and street signs, and
should utilize the system’s audio cues while
driving.
The navigation system does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. Their
observance always remains in the driver’s
personal responsibility. Maps do not cover all
areas nor all routes within an area.
Traffic regulations always have priority over
any route recommendations given.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
GWarning!
Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving.
Please always use navigation announcements
instead of consulting the map display for
directions. Consulting the symbols or map
display for directions may cause you to divert
your attention from driving and increase your
risk of an accident.

Intermittent wiping
Only switch on intermittent wiping under wet
weather conditions or in the presence of
precipitation.
When you select intermittent wiping, the rain
sensor is activated. The rain sensor sets a
suitable wiping interval depending on the
wetness of the sensor surface automatically.
! Do not leave windshield wipers on an
intermittent setting when the vehicle is
taken to an automatic car wash or during
windshield cleaning. Windshield wipers will
operate in the presence of water sprayed
on the windshield, and windshield wipers
may be damaged as a result.
! If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical
effects may cause the windshield wipers to
wipe in an undesired fashion. This could
then damage the windshield wiper blades
or scratch the windshield. You should
therefore switch off the windshield wipers
when weather conditions are dry.
XTurn the combination switch to position
004E or 004F .
After the initial wipe, pauses between
wipes are controlled by the rain sensor
automatically.
Intermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or
out of the vehicle from being sprayed.
Intermittent wiping will be continued when all
doors are closed and
R the automatic transmission is in drive
position D or reverse gear R
or
R the wiper setting is changed using the
combination switch
Single wipeXPress the combination switch briefly in
direction of arrow 0087 to the resistance
point.
The windshield wipers wipe one time
without washer fluid.
Wiping with washer fluid
XPress the combination switch in direction
of arrow 0087 past the resistance point.
The windshield wipers operate with washer
fluid.
i To prevent smears on the windshield or
noisy/chattering wiper blades, wipe with
washer fluid every now and then even when
it is raining.
For information on filling up the washer
reservoir, see “Washer system and headlamp
cleaning system” ( Y page 409).
For information on cleaning the headlamps
with washer fluid, see “Headlamp cleaning
system” ( Y page 303).
Problems with wipers
! If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off
immediately.
For safety reasons, do the following before
attempting to remove any blockage:
R Stop the vehicle in a safe location.
R Remove the SmartKey from the starter
switch.
or
R Turn off the engine by pressing the
KEYLESS-GO start/stop button and
open the driver’s door (with the driver’s

Safety notes
When activated, the DISTRONIC PLUS
adaptive cruise control system increases the
driving convenience afforded by the cruise
control while traveling on expressways and
other major roadways.
R If the DISTRONIC PLUS distance sensor
detects a slower moving vehicle directly
ahead, your vehicle speed will be reduced
so that you follow that vehicle at your
preset following distance.
R If there is no vehicle directly ahead of you,
the DISTRONIC PLUS will function in the
same way as standard cruise control
( Y page 328).
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!
