Environmental protection
General notes
H
Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
Our objectives are to use the natural resour-
ces which form the basis of our existence on
this planet sparingly and in a manner which
takes the requirements of both nature and
humanity into consideration.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally-responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tyre wear depend on
the following factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors. Therefore,
please bear the following in mind:
Operating conditions:
R avoid short trips, as these increase fuel
consumption.
R observe the correct tyre pressure.
R do not carry any unnecessary weight in the
vehicle.
R remove the roof rack once you no longer
need it.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R all maintenance work should be carried out
at a qualified specialist workshop.
Personal driving style:
R do not depress the accelerator pedal when
starting the engine.
R do not warm up the engine when the vehicle
is stationary.
R drive carefully and maintain a safe distance
from the vehicle in front.
R avoid frequent, sudden acceleration and
braking. R
change gear in good time and use each gear
only up to Ôof its maximum engine speed.
R switch off the engine in stationary traffic.
R monitor the vehicle's fuel consumption. Take-back of end-of-life vehicles
EU countries only:
Mercedes-Benz will take back your end-of-life
vehicle for environmentally friendly disposal in
accordance with the European Union (EU) End-
Of-Life Vehicles Directive.
A network of vehicle take-back points and dis-
mantlers has been established for you to return
your vehicle. You can leave it at any of these
points free of charge. This makes an important
contribution to closing the recycling circle and
conserving resources.
For further information about the recycling and
disposal of end-of-life vehicles, and the take-
back conditions, please visit the national
Mercedes-Benz website for your country. Genuine Mercedes-Benz parts

PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when physi-
cal limits are exceeded and the vehicle under- steers or oversteers severely
R vehicles with the Driving Assistance package:
when a driver assistance system intervenes
powerfully or the radar sensor system detects
an imminent danger of collision in certain sit- uations
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detected:
R the front seat belts are pre-tensioned
R if the vehicle skids, the front side windows are
closed
R vehicles with the memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavourable
position
If the hazardous situation passes without result- ing in an accident, PRE-SAFE ®
slackens the belt
pre-tensioning. All settings made by PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back slightly
when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®

tion about the convenience function can be
found under "Belt adjustment" (Y page 47).PRE-SAFE
®
PLUS (anticipatory occu-
pant protection PLUS)
Introduction PRE-SAFE
®
PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE ®
PLUS is able to detect that a head-on or rear-end
collision is imminent. In certain hazardous sit-
uations, PRE-SAFE ®
PLUS takes pre-emptive
measures to protect the vehicle occupants. Important safety notes The intervention of PRE-SAFE
®
PLUS cannot
prevent an imminent collision.
The driver is not warned before the intervention
of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene:
R if the vehicle is reversing
R when the vehicle is towing a trailer and there
is a risk of a rear-end collision
When driving, or when parking or exiting a park- ing space with assistance from Active Parking
Assist, PRE-SAFE ®
PLUS will not apply the
brakes.
Function PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the radar sensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following measures
depending on the hazardous situation detected:
R if the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned
R if the radar sensor system detects that a rear-
end collision is imminent:
- the rear hazard warning lamps are activa-
ted and flash at a higher frequency
- the brake pressure is increased if the driver
applies the brakes when the vehicle is sta-
tionary
- the seat belts are pre-tensioned
The PRE-SAFE ®
PLUS braking application is can-
celled:
R if the accelerator pedal is depressed when a
gear is engaged
R if the risk of a collision passes or is no longer
detected
R if DISTRONIC PLUS indicates an intention to
pull away
If the hazardous situation passes without result- ing in an accident, the original settings are
restored. 58

WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking X
Keep the brake pedal depressed firmly 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. BAS PLUS (Brake Assist System
PLUS) with Cross-Traffic Assist
General information BAS PLUS can help you to minimise the danger
of collision with a vehicle or a pedestrian and
reduce the effects of such a collision. If BAS
PLUS detects a danger of collision, you are
assisted when braking.
i Observe the important safety notes in the
"Driving safety systems" section (Y page 67).
BAS PLUS is available only on vehicles with the
Driving Assistance package.
For BAS PLUS to assist you when driving, the
radar sensor system and the camera system
must be operational.
With the help of a sensor system and a camera
system, BAS PLUS can detect obstacles:
R that are in the path of your vehicle for an
extended period of time
R that cross the path of your vehicle
In addition, pedestrians in the path of your vehi-
cle can be detected.
BAS PLUS detects pedestrians using typical
characteristics such as the body contours and
posture of a person standing upright.
If the radar sensor system or the camera system
is malfunctioning, BAS PLUS functions are
restricted or no longer available. The brake sys- tem is still available with complete brake boost-ing effect and BAS. i
Observe the restrictions described in the
"Important safety notes" section
(Y page 68).
Important safety notes G
WARNING
BAS PLUS cannot always clearly identify
objects and complex traffic situations.
In such cases, BAS PLUS may:
R intervene unnecessarily
R not intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation. G
WARNING
BAS PLUS cannot always clearly identify peo- ple, this is especially the case if they are mov-
ing. BAS PLUS cannot intervene in these
cases. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
BAS PLUS does not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R when cornering
As a result, BAS PLUS may not intervene in all
critical situations. There is a risk of an acci-
dent.
Always pay careful attention to the traffic sit- uation and be ready to brake.
In the event of snowfall or heavy rain, detection
can be impaired.
Detection by the radar sensor system is also
impaired in the following situations:
R dirt on the sensors or obscured sensors
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks 68
Driving safety systemsSafety

R
a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
R vehicles quickly moving into the radar sensor
system detection range
Detection by the camera system is also impaired
in the following situations:
R dirt on the camera or obscured camera
R glare on the camera system, e.g. from the sun
being low in the sky
R darkness
R if:
- pedestrians move quickly, e.g. into the path
of the vehicle
- the camera system no longer detects a
pedestrian as a person due to special cloth-
ing or other objects
- a pedestrian is concealed by other objects
- the typical outline of a pedestrian is not
distinguishable from the background
Following damage to the front end of the vehicle, have the radar sensor settings and operation
checked at a qualified specialist workshop. This
also applies to collisions at low speeds where
there is no visible damage to the front of the
vehicle.
Following damage to the windscreen, have the
configuration and operation of the camera sys-
tem checked at a qualified specialist workshop.
Function To avoid a collision, BAS PLUS calculates the
brake pressure necessary if:
R you approach an obstacle and
R BAS PLUS has detected a danger of collision
At speeds of under30 km/h: if you depress the
brake pedal, BAS PLUS is activated. Braking
assistance from BAS PLUS is provided at the last
possible moment.
At speeds of above30 km/h:if you depress the
brake pedal sharply, BAS PLUS automatically
increases the brake pressure to a degree suited to the traffic situation.
BAS PLUS provides braking assistance in haz-
ardous situations with vehicles in front within a
speed range between 7 km/h and 250 km/h. At speeds of up to approximately 70 km/h, BAS
PLUS can react to:
R stationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
R obstacles crossing your path that move in the
detection range of the sensors and are detec- ted
i If BAS PLUS demands particularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
) are activated simulta-
neously (Y page 57).
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual, if:
R you release the brake pedal
R the danger of collision has passed
R no obstacle is detected in front of your vehicle
R you depress the accelerator pedal
R you activate kickdown COLLISION PREVENTION ASSIST
PLUS
General information i
Observe the "Important safety notes" sec-
tion (Y page 67).
COLLISION PREVENTION ASSIST PLUS consists of a distance warning function with an autono-
mous braking function and Adaptive Brake
Assist.
COLLISION PREVENTION ASSIST PLUS can help you to minimise the danger of collision with thevehicle in front or reduce the effects of such a
collision.
If COLLISION PREVENTION ASSIST PLUS
detects a danger of collision, you will be warned
visually and audibly. If you do not react to the
visual and audible collision warning, autono-
mous braking can be initiated in critical situa-
tions. If you apply the brake yourself in a critical situation, the COLLISION PREVENTION ASSIST
PLUS Adaptive Brake Assist assists you. Driving safety systems
69Safety Z

Important safety notes
In particular, the detection of obstacles can be
impaired in the following situations:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
R new vehicles or after the COLLISION PRE-
VENTION ASSIST PLUS system has been serv- iced
Observe the important safety notes in the
"Running-in notes" section (Y page 132).
Following damage to the front end of the vehicle, have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at low
speeds where there is no visible damage to the front of the vehicle.
Activating/deactivating The COLLISION PREVENTION ASSIST PLUS is
automatically active when the ignition is
switched on.
You can activate or deactivate COLLISION PRE-
VENTION ASSIST PLUS in the on-board com-
puter (Y page 233). When the system is deac-
tivated, the distance warning function and the
autonomous braking function are also deactiva-
ted.
If COLLISION PREVENTION ASSIST PLUS is
deactivated, the æsymbol appears on the
assistance display.
Distance warning function General information
The distance warning function can help you to
minimise the risk of a rear-end collision with a
vehicle ahead or reduce the effects of such a
collision. If the distance warning function
detects a risk of collision with the vehicle in
front, you will be warned visually and audibly. Important safety notes
i Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 67). G
WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation; do not rely on the distance warning
function alone.
Function The distance warning function issues a warning at speeds:
R of approximately 30 km/h or more if, over
several seconds, the distance maintained to
the vehicle travelling in front is insufficient.
The · distance warning lamp will then
light up on the instrument cluster.
R of approximately 7 km/h or more if you are
rapidly approaching a vehicle in front. An
intermittent warning tone will then sound and
the · distance warning lamp will light up
on the instrument cluster. 70
Driving safety systemsSafety

X
Brake immediately to increase the distance
from the vehicle in front.
or X Take evasive action provided it is safe to do
so.
Due to the nature of the system, certain com-
plex but non-critical driving conditions may also
cause the system to display a warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of approximately 70 km/h, the
distance warning function can also react to sta- tionary obstacles, such as stopped or parked
vehicles.
Autonomous braking function If the driver does not react to the distance warn-
ing signal in a critical situation, COLLISION PRE-
VENTION ASSIST PLUS can assist with the
autonomous braking function.
Vehicles without DISTRONIC PLUS: the
autonomous braking function is available in the following speed ranges:
R 7–105 km/h for moving objects
R 7–50 km/h for stationary objects
Vehicles with DISTRONIC PLUS: the autono-
mous braking function is available in the follow-
ing speed ranges:
R 7–200 km/h for moving objects
R 7–50 km/h for stationary objects
Due to the nature of the system, complex but
non-critical driving conditions may also cause
the autonomous braking function to engage.
If the autonomous braking function demands
particularly high braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously (Y page 57).
Adaptive Brake Assist General information
i Observe the "Important safety notes" sec-
tion (Y page 67).
With the help of the radar sensor system, Adap- tive Brake Assist can detect obstacles that are in
the path of your vehicle for an extended period
of time. If Adaptive Brake Assist detects a risk of colli-
sion with the vehicle in front, it calculates the
braking force necessary to avoid a collision. If
you apply the brakes forcefully, Adaptive Brake
Assist will automatically increase the braking
force to a level suitable for the traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardous situations at speeds above
7 km/h. It uses the radar sensor system to
assess the traffic situation.
Up to a speed of approximately 250 km/h,
Adaptive Brake Assist is capable of reacting to
moving objects that have already been detected
as such at least once over the period of obser-

Up to a speed of approximately 70 km/h, Adap-
tive Brake Assist reacts to stationary obstacles.
If Adaptive Brake Assist demands a particularly
high brake pressure, preventative passenger
protection measures (PRE-SAFE ®
) are activated
simultaneously (Y page 57).
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if: R you release the brake pedal
R a danger of collision with the vehicle in front
no longer exists
R no obstacle is detected in front of your vehicle
Adaptive Brake Assist is then deactivated.
