Protection of the environment
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. Returning an end-of-life vehicle
EU countries only:
Mercedes-Benz will take back your old vehicle to dispose of it in an environmentally-respon-sible manner in accordance with the Euro-
pean Union (EU) End of Life Vehicles Direc-
tive.
There is a network of return points and dis-
assembly plants available. You can return
your vehicle to these plants free of charge.
This makes a valuable contribution to the
recycling process and the conservation of
resources.
For further information on recycling old vehi- cles, recovery and the terms of the policy,
visit the Mercedes-Benz homepage. Genuine Mercedes-Benz parts
H
Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
! Airbags and seat belt tensioners, as well
as control units and sensors for these
restraint systems, may be installed in the
following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console Introduction

Have roll bars checked immediately at a quali-
fied specialist workshop. G
WARNING
If you place objects or clothing on the roll bar covers, these could impair roll bar extension.
The roll bars may then not protect the vehicle occupants as intended. In addition, objects
could endanger the vehicle occupants when
the roll bar is extending. This poses an
increased risk of injury or even fatal injury.
Ensure that the movement area of the roll bar covers is kept clear. Always stow all objects in
the vehicle correctly. The roll bars are located in the rear area of the
vehicle under the two outer rear compart-
ment trim covers.
The roll bars are extended automatically if
systems detect that the vehicle is in danger of
overturning. The two rear compartment trim
covers are opened and the roll bars are exten- ded within fractions of a second.
Once the roll bars are extended, you can no
longer lower them. An open roof can no lon-
ger be closed. In this case, visit the nearest
qualified specialist workshop. PRE-SAFE
®
(anticipatory occupant
protection)
Introduction PRE-SAFE
®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations. Important safety notes !
Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is a risk that the seats and/or the objects could be damaged.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
R on vehicles with DISTRONIC PLUS: if
BAS PLUS brakes hard or the radar sensor
system detects an imminent danger of col- lision in certain situations
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the seat belts are pre-tensioned.
R if the vehicle skids, the side windows are
closed so that only a small gap remains.
R the front-passenger seat is adjusted if it is
in an unfavourable position.
R Vehicles with a multicontour seat or
active multicontour seat: the air pres-
sure in the side bolsters of the backrest is
increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. All settings made by
PRE-SAFE ®
can then be reversed. 56

Brakes
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)
General notes i
Observe the "Important safety notes" sec-
tion (Y page 70).
BAS PLUS is only available on vehicles with
DISTRONIC PLUS.
For BAS PLUS to assist you, the radar sensor system must be operational.
With the aid of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
If the radar sensor system is malfunctioning,
BAS PLUS will not be available. The brake
system is still available with complete brake
boosting effect and BAS.
BAS PLUS can help you to minimise the risk of a collision with a vehicle or reduce the effects
of such a collision. If BAS PLUS detects a
danger of collision, you are assisted when
braking.
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 does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
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, detec-
tion can be impaired.
Detection by the radar sensor system is also
impaired in the event of:
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
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different
line
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper- ation checked at a qualified specialist work-
shop. This also applies to collisions at slow
speeds where there is no visible damage to
the front of the vehicle.
Function To avoid a collision, BAS PLUS calculates the
brake force necessary if:
R you approach an obstacle and
R BAS PLUS has detected a risk of collision
When driving at a speed under 30 km/h : if
you depress the brake pedal, BAS PLUS is
activated. Braking assistance from BAS PLUS
is carried out at the last possible moment.
When driving at a speed above 30 km/h : if
you depress the brake pedal sharply, BAS 72

WARNING
If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This increa-
ses the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 275) as well as dis-
play messages (Y page 250). ADAPTIVE BRAKE
i Observe the "Important safety notes" sec-
tion (Y page 70).
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 196) and
hill start assist (Y page 158). PRE-SAFE

General notes i
Observe the "Important safety notes" sec-
tion (Y page 70).
PRE-SAFE ®
Brake is only available on vehicles
with DISTRONIC PLUS.
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be opera-
tional.
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.
PRE-SAFE ®
Brake can help you to minimise
the risk of a collision with a vehicle ahead, and reduce the effects of such a collision. If PRE-
SAFE ®
Brake has detected a risk of collision,
you will be warned visually and acoustically as
well as by automatic braking. PRE-SAFE ®Brake cannot prevent a collision without your
intervention.
Important safety notes G
WARNING
PRE-SAFE ®
Brake will initially brake your vehi-
cle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you also brake. Automatic
emergency braking cannot prevent a colli-
sion. There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action. G
WARNING
PRE-SAFE ®
Brake cannot always clearly iden-
tify objects and complex traffic conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brake warns you. Terminate the
intervention in a non-critical driving situation.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col- lision, you must apply the brakes yourself. G
WARNING
PRE-SAFE ®
Brake does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, PRE-SAFE ®
Brake may neither
give warnings nor intervene in all critical sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Driving safety systems

In the event of snowfall or heavy rain, detec-
tion can be impaired.
Detection by the radar sensor system is also
impaired in the event of:
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
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different
line
Following damage to the front end of the vehi-
cle, have the radar sensor settings and oper- ation checked at a qualified specialist work-
shop. This also applies to collisions at slow
speeds where there is no visible damage to
the front of the vehicle.
Function X
To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 238).
When PRE-SAFE ®
Brake is deactivated, the
æ symbol appears in the assistance
graphic in the multifunction display.
This function will issue a warning if:
R at a speed of around 30 km/h or more, the
distance maintained to the vehicle travel-
ling in front is insufficient for several sec-
onds.
The · distance warning lamp then lights
up in the instrument cluster.
R at a speed of approximately 7 km/h or
more, you rapidly approach a vehicle in
front.
An intermittent warning tone will then
sound and the ·distance warning lamp
will light up in the instrument cluster.
X Brake immediately to defuse the situation.
or
X Take evasive action provided it is safe to do
so. The PRE-SAFE
®
Brake function can also brake
the vehicle automatically under the following
conditions:
R the driver and front-passenger have their
seat belts fastened
and
R the vehicle speed is between approx-
imately 7 km/h and 200 km/h
At speeds of up to approximately 70 km/h,
PRE-SAFE ®
Brake can also detect stationary
objects. Examples of stationary objects are
stopped or parked vehicles.
i If there is an increased risk of collision,
preventive passenger protection measures
(PRE-SAFE ®
) are activated.
If the risk of collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking,
up to the point of full brake application. Auto- matic emergency braking is not performed
until immediately prior to an imminent acci-
dent.
You can prevent the intervention of the PRE-
SAFE ®
Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you manoeuvre to avoid the obstacle
R there is no longer any danger of a collision
R there is no longer an obstacle detected in
front of your vehicle STEER CONTROL
General notes STEER CONTROL helps you by transmitting a
noticeable steering force to the steering
wheel in the direction required for vehicle
stabilisation. 78
