Protection of the environment
General notes
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
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 tire wear are affected by these factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel con-
sumption.
R always make sure that the tire pressures
are correct.
R do not carry any unnecessary weight.
R remove roof racks once you no longer need
them.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have service work 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 andbraking.
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 keep an eye on the vehicle's fuel consump-
tion.
Environmental concerns and recom-
mendations
Wherever the operating instructions require
you to dispose of materials, first try to regen-
erate or re-use them. Observe the relevant
environmental rules and regulations when
disposing of materials. In this way you will
help to protect the environment.
Genuine Mercedes-Benz parts
HEnvironmental note
Daimler AG also supplies reconditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the same Limited Warranty entitlements as newparts.
!Air bags and Emergency Tensioning Devi-
ces, 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 cockpit
R instrument cluster
R center console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-tems.
Have aftermarket accessories installed at a qualified specialist workshop.
20Introduction

ROnly secure a child in a rearward-facing
child restraint system on the front-
passenger seat when the front-passenger
front air bag is deactivated. If the
PASSENGER AIR BAG OFF indicator lamp is
permanently lit, the front-passenger front
air bag is deactivated ( Ypage 39).
R Always observe the instructions and safety
notes on the "Occupant Classification Sys- tem (OCS)" ( Ypage 47) and on "Children
in the vehicle" ( Ypage 54) in addition to
the child restraint system manufacturer's
installation instructions.
Objects in the vehicle interior may pre-
vent an air bag from functioning correctly. Before starting your journey and to avoid risks
resulting from the speed of the air bag as it
deploys, make sure that:
R there are no people, animals or objects
between the vehicle occupants and an airbag.
R there are no objects between the seat, door
and B-pillar.
R no hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
R no accessories, such as cup holders, are
attached to the vehicle within the deploy-
ment area of an air bag, e.g. to doors, side
windows, rear side trim or side walls.
R no heavy, sharp-edged or fragile objects
are in the pockets of your clothing. Store
such objects in a suitable place.
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objectsto it.
GWARNING
Sensors to control the air bags are located in the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensors being impaired. The airbags might therefore not function properly
any more. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk ofinjury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan-
eling carried out at a qualified specialist work- shop.
Front air bags
Driver's air bag :deploys in front of the
steering wheel. Front-passenger front air bag ;deploys in front of and above the glove
box.
When deployed, the front air bags offer addi- tional head and thorax protection for the
occupants in the front seats.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
inform you about the status of the front-
passenger front air bag ( Ypage 39).
The front-passenger front air bag will only
deploy if:
R the system, based on the OCS weight sen-
sor readings, detects that the front-
passenger seat is occupied ( Ypage 47).
The PASSENGER AIR BAG ON indicator
lamp is lit ( Ypage 47)
R the restraint system control unit predicts a
high accident severity

COLLISION PREVENTION ASSIST PLUS
General information
COLLISION PREVENTION ASSIST PLUS con-
sists of a distance warning function with an
autonomous emergency braking function and adaptive Brake Assist.
COLLISION PREVENTION ASSIST PLUS can
help you to minimize the risk of a front-end
collision with a vehicle ahead or reduce the
effects of such a collision.
If COLLISION PREVENTION ASSIST PLUS
detects that there is a risk of a collision, you
will be warned visually and acoustically. If you
do not react to the visual and audible collision
warning, autonomous braking can be initiated in critical situations. If you apply the brake
yourself in a critical situation, the COLLISION PREVENTION ASSIST PLUS adaptive Brake
Assist assists you.
Important safety notes
In particular, the detection of obstacles can
be impaired if:
R there is dirt on the sensors or anything else
covering the sensors
R there is snow or heavy rain
R there is interference by other radar sources
R there are strong radar reflections, for
example in parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in front on a different line
R new vehicles or after a service on the COL-
LISION PREVENTION ASSIST PLUS system
Observe the notes in the section on break- ing-in ( Ypage 134).
Following damage to the front end of the vehi- cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.
Distance warning function
Important safety notes
iObserve the "Important safety notes" sec-
tion for driving safety systems ( Ypage 60).
GWARNING
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.
GWARNING
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 and do not rely solely on the distance
warning function.
Function X To activate/deactivate: activate or deac-
tivate the distance warning function in the
on-board computer ( Ypage 203).
Vehicles with a black and white multi-
function display: when the distance warning
function is activated, the Äsymbol
appears in the status overview in the multi-
function display.
Vehicles with a color multifunction dis-
play : when the distance warning function is
deactivated, the æsymbol appears in the
assistance graphics in the multifunction dis-
play in display.
62Driving safety systems
Safety

The distance warning function can help you tominimize the risk of a front-end collision with
a vehicle ahead or reduce the effects of such
a collision. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically.
Starting at a speed of around 4 mph (7 km/h),
the distance warning function warns you if
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 in order 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, particularly
complicated but non-critical driving condi-
tions may also cause the system to display a
warning.
With the help of the radar sensor system, the distance warning function can detect obsta-
cles that are in the path of your vehicle for an
extended period of time.
Up to a speed of around 44 mph (70 km/ h),
the distance warning function can also react
to stationary obstacles, such as stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision,
the system will initially alert you both visually
and acoustically.
Autonomous braking function
If the driver does not react to the distance
warning signal in a critical situation, COLLI-
SION PREVENTION ASSIST PLUS can assist
with the autonomous braking function.
The autonomous braking function:
R gives the driver more time to react to criti-
cal driving situations
R can help the driver to avoid an accident or
R reduces the effects of an accident Vehicles without DISTRONIC PLUS:
the
autonomous braking function is available in
the following speed ranges:
R 5 - 65 mph (7 - 105 km/h) for moving
objects
R 5 - 31 mph (7 - 50 km/h) for stationary
objects
Vehicles with DISTRONIC PLUS: the auton-
omous braking function is available in the fol- lowing speed ranges:
R 5 - 124 mph (7 - 200 km/h) for moving
objects
R 5 - 31 mph (7 - 50 km/h) for stationary
objects
If the autonomous braking function requires a particularly high braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously.
Adaptive Brake Assist
iObserve the "Important safety notes" sec-
tion ( Ypage 60).
Adaptive Brake Assist provides braking assis- tance in hazardous situations at speeds
above 4 mph (7 km/h). It uses radar sensor
technology to assess the traffic situation.
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
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.
GWARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
