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:
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.
HEnvironmental note
Have a defective high-voltage battery dis-
posed of in an environmentally-responsible
manner. Contact a qualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use an authorized Mercedes-Benz Center
for this purpose.
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

Introduction
Z

RAdjust the seats properly before beginning
your journey. Always make sure that the seat
is in an almost upright position. The center of
the head restraint must support the head at
about eye level.
RMove the driver's and front-passenger seats
as far back as possible. The driver's seat posi-
tion must allow the vehicle to be driven safely.
ROnly hold the steering wheel on the outside.
This allows the air bag to be fully deployed.
RAlways lean against the backrest while driv-
ing. Do not lean forwards or lean against the
door or side window. You may otherwise be in
the deployment area of the air bags.
RAlways keep your feet in the footwell in front
of the seat. Do not put your feet on the dash-
board, for example. Your feet may otherwise
be in the deployment area of the air bag.
RFor this reason, always secure persons less
than 5 ft (1.50 m)tall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
RAlways secure children under twelve years of age and less than 5 ft (1.50m)tall in suitable
child restraint systems.
RChild restraint systems should be installed on
the rear seats.
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 47).
RAlways observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (
Ypage 54) and on "Children in the
vehicle" (Ypage 62) in addition to the child
restraint system manufacturer's installation
and operating instructions.
Objects in the vehicle interior may prevent
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:
Rthere are no people, animals or objects
between the vehicle occupants and an air
bag.
Rthere are no objects between the seat, door
and B-pillar.
Rno hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
Rno accessories, such as cup holders, are
attache d to the vehicle within the deployment
area of an air bag, e.g. to doors, side windows,
rear side trim or side walls.
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
52Occupant safety
Safety

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 front seats.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps inform you about
the status of the front-passenger air bag
(
Ypage 47).
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 54). The
PASSENGER AIR BAG ON indicator lamp is lit
(
Ypage 54)
Rthe restraint system control unit predicts a
high accident severity
Driver's knee bag
Driver's knee bag :deploys under the steering
column. The driver's knee bag is always
deployed along with the driver's front air bag.
The driver's knee bag offers additional thigh,
knee and lower leg protection for the occupant
in the driver's seat.
Side impact air bags
GWARNING
Unsuitable seat covers could restrict or even
prevent the deployment of the air bags inte-
grated into the seats. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. In addition, the func- tion of the Occupant Classification System
(OCS) could be restricted. This poses an
increased risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Front side impact air bags :and rear side
impact air bags ;deploy next to the outer bol-
ster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax protection. However, it does
not protect the:
Rhead
Rneck
Rarms
In the event of a side impact, the side impact air
bag is deployed on the side on which the impact
occurs.
The side impact air bag on the front-passenger
side (front) deploys under the following condi-
tions:
Rthe OCS system detects that the front-
passenger seat is occupied or
Rthe belt tongue is engaged in the belt buckle
of the front-passenger seat
If the belt tongue is engaged in the belt buckle,
the side impact air bag on the front-passenger
side deploys if an appropriate accident situation
occurs. In this case, deployment is independent
of whether the front-passenger seat is occupied
or not.
Occupant safety53
Safety
Z

air bag must be deployed on time, at the start of
the collision.
The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
Rdistribution of the force during the impact
Rcollision angle
Rdeformation characteristics of the vehicle
Rcharacteristics of the object with which the
vehicle has collided
Factors which can only be seen and measured
after the collision has occurred do not play a
decisive role in the deployment of an air bag, nor
do they provide an indication of air bag deploy-
ment.
The vehicle may be considerably deformed with-
out an air bag being deployed. This is the case if
only relatively easily deformable parts have
been hit and a high rate of deceleration has not been reached. Conversely, an air bag may be
deployed even though the vehicle suffers only
minor deformation. This is the case if, for exam-
ple, very rigid vehicle parts such as the longitu-
dinal body members are hit in an accident and
the rate of deceleration is sufficient.
If the restraint system control unit detects a side impact or that the vehicle is rolling over, the rel-
evant restraint system components are
deployed independently of one another depend-
ing on the anticipated type of accident.
RSide impact air bags on the side of the colli-
sion, regardless of Emergency Tensioning
Device and use of the seat belt on the driver's
side and the outer seats on the second row
The side impact air bag on the front-
passenger side deploys under the following
conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the belt tongue has engaged in the belt
buckle of the front-passenger seat.
RWindow curtain air bag on the side of the col-
lision, regardless of seat belt use and whether
front-passenger seat is occupied
RFront Emergency Tensioning Devices, if the
system determines that they can offer addi-
tional protection for the vehicle occupants in
this situation
RRear Emergency Tensioning Devices in cer-
tain situations if the vehicle rolls over
RWindow curtain air bags on the driver's and
front-passenger sides in certain rollover sit- uations if the system determines that they
can offer additional protection to that provi-
ded by the seat belt
iNot all air bags are deployed in an accident.
The various air bag systems work independ-
ently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration, and the apparent type of accident:
Rfrontal collision
Rside impact
Rrollover
PRE-SAFE®(anticipatory occupant
protection system)
Introduction
PRE-SAFE®takes preemptive measures to pro-
tect occupants in certain hazardous situations.
Important safety notes
!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.
Despite your vehicle being equipped with the
PRE-SAFE
®system, the possibility of personal
injuries occurring as a result of an accident can-
not be eliminated. 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:
Rin emergency braking situations, e.g. when
BAS is activated
Rin critical driving situations, e.g. when physi-
cal limits are exceeded and the vehicle under-
steers or oversteers severely
Rvehicles 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
