Protecting 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:
Roperating conditions of your vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
Ravoid short trips as these increase fuel con-
sumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer need
them.
Ra regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
Ralways have service work carried out at a
qualified specialist workshop.
Personal driving style:
Rdo not depress the accelerator pedal when
starting the engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintain a safe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear
only up to Ôof its maximum engine speed.
Rswitch off the engine in stationary traffic.
Rkeep 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 regenerate or
re-use them. Observe the relevant environmen-
tal 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 new
parts.
!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:
Rdoors
Rdoor pillars
Rdoor sills
Rseats
Rcockpit
Rinstrument cluster
Rcenter console
Do not install accessories such as audio sys-
tems in these areas. Do not carry out repairs or welding. You could impair the operating
efficiency of the restraint systems.
Have aftermarket accessories installed at a
qualified specialist workshop.
You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels as
well as accessories relevant to safety which
have not been approved by Mercedes-Benz. This
could lead to malfunctions in safety-relevant

area of an air bag, e.g. to doors or side win-
dows
Rno 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 objects
to 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 air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
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
!Do not place heavy objects on the front-
passenger seat. This could cause the system
to identify the seat as being occupied. In the
event of an accident, the restraint systems on
the front-passenger side may be triggered
and have to be replaced.
Driver's air bag :deploys in front of the steer-
ing 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 occu-
pants in the driver's and front-passenger seats.
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the front-
passenger front air bag (
Ypage 41).
The front-passenger front air bag will only
deploy if:
Rthe system, based on the OCS weight sensor
readings, detects that the front-passenger
seat is occupied (
Ypage 47). The
PASSENGER AIR BAG OFF indicator lamp is
not lit (
Ypage 48)
Rthe restraint system control unit predicts a
high accident severity
Knee bags
Driver's knee bag :deploys under the steering
column and front-passenger knee bag ;under
the glove box. The driver's and front-passenger
knee bags are triggered together with the front
air bags.
The driver's and front-passenger knee bags
offer additional thigh, knee and lower leg pro-
tection.
Side impact air bags
GWARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they are designed to do. In addition, the operation of
the occupant classification system (OCS)
46Occupant safety

Rsetting a more favorable seat position for the
front-passenger seat.
Rvehicles with a multicontour seat: increasing
the air pressure in the side bolsters of the seat
backrest.
!Make sure that there are no objects in the
footwell or behind the seats. There is a danger that the seats and/or objects could be dam-
aged when PRE-SAFE
®is activated.
Should an accident not occur, the preventative
measures taken are reversed. Certain settings
must be made yourself.
XIf the seat belt pre-tensioning is not reduced,
move the seat backrest back slightly.
Seat belt pre-tensioning is released.
PRE-SAFE®PLUS (anticipatory occu-
pant protection system 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 about the intervention
of PRE-SAFE
®PLUS.
PRE-SAFE®PLUS does not intervene if the vehi-
cle is backing up.
When driving, or when parking or exiting a park-
ing space with assistance from Parking Pilot,
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:
Rif the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned.
Rif the radar sensor system detects that a rear-
end collision is imminent:
-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-
celed:
Rif the accelerator pedal is depressed when a
gear is engaged
Rif the risk of a collision passes or is no longer
detected
Rif Distance Pilot DISTRONIC indicates an
intention to pull away
If the hazardous situation passes without result-
ing in an accident, the original settings are
restored.
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
Rthe hazard warning lamps are switched on
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rthe electrically adjustable steering wheel is
raised when the driver's door is opened
Rthe engine is switched off and the fuel supply
is switched off
Rvehicles with mbrace: automatic emergency
call
Children in the vehicle
Important safety notes
If a child younger than twelve years old and
under 5 ft (1.50 m)in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.

Braking
XKeep the brake pedal firmly depressed 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.
Brake Assist with cross-traffic func-
tion
General information
Brake Assist with cross-traffic function can help
you to minimize the risk of a collision with a
vehicle or a pedestrian and reduce the effects of
such a collision. If Brake Assist with cross-traffic
function detects a danger of collision, you are
assisted when braking.
iObserve the "Important safety notes" sec-
tion (Ypage 60).
Brake Assist with cross-traffic function is only
available in vehicles with the Driving Assistance
package.
For Brake Assist with cross-traffic function to
assist you when driving, the radar sensor system
and the camera system must be operational.
The sensor system and camera system help
Brake Assist with cross-traffic function detect
obstacles:
Rthat are in the path of your vehicle for an
extended period of time
Rthat cross the path of your vehicle
In addition, pedestrians in the path of your vehi-
cle can be detected.
Brake Assist with cross-traffic function detects
pedestrians using typical characteristics such
as body contours and the posture of a person
standing upright.
If the radar sensor system or the camera system
is malfunctioning, Brake Assist with cross-traffic function is restricted or no longer available. The
brake system is still available with comple te
b

rake boosting effect and BAS.
iObserve the restrictions described in the
"Important safety notes" section
(
Ypage 61).
Important safety notes
GWARNING
Active Brake Assist with cross-traffic function cannot always clearly identify objects and
complex traffic situations.
In such cases, Active Brake Assist with cross-
traffic function might:
Rissue an unnecessary warning or brake
Rissue no warning or not brake

uation; do not rely on the Active Brake Assist
with cross-traffic function alone.
Always be ready to brake and possibly take
evasive action.
GWARNING
Brake Assist with cross-traffic function can-
not always clearly identify people, particularly if they are moving. Brake Assist with cross-
traffic function 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.
GWARNING
Active Brake Assist with cross-traffic function does not react:
Rto small people, e.g. children
Rto animals
Rto oncoming vehicles
Rwhen cornering
As a result, Active Brake Assist with cross-
traffic function may not warn you or engage 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, the rec-
ognition can be impaired.
