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 amanner
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 conditionsofy our 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.
Rar egularly 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
startin gthe engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintain asafe 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 Operator's Manual requires you to
dispose of materials, first try to regenerate or re-
use them. Observe the relevant environmental
rules and regulations when disposing of materi-
als. In this way you will help to protect the envi-
ronment.
Genuine Mercedes-Benz parts
HEnvironmental note
Daimler AG also suppliesr econditioned 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
Rinstrumentc luster
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 malfunction sinsafety-relevant

Introduction

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 occupantsa nd an air bag
Rthere are no objectsbetween the seat, door
and B-pillar
Rthere are no hard objects, e.g. coat hangers,
hanging on the grab handles or coat hooks
Rno accessories, such as cup holders, are
attached 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 object sare in
the pocket sofyour clothing. Store such
object sinas uitable 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. Modification sorwork not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensor sbeing impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protec tvehicle occupantsast hey 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 aqualified specialist work-
shop.
Front air bags
!Do not place heavy object sonthe front-
passenger seat. This could cause the system
to identif ythe 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 frontoft he steer-
ing wheel. Front-passenger fronta ir bag;
deploys in frontofa nd above the glove box.
When deployed, the fronta ir bags offer addi-
tional head and thorax protection for the occu-
pants in the fronts eats.

62Driving safety systems
Safety

The distance warning function may not give
warnings 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.
Always adapt your speed to suit the prevailing
road and traffic conditions.
GWARNING
The distance warning function cannot always
clearly identify object sand complex traffic
situations.
In such cases, the distance warning function
may:
Rgive an unnecessary warning
Rnot give awarning
There is arisk of an accident.
Always pay careful attention to the traffic sit-
uation and do not rely solely on the distance
warning function.
Function
Starting at aspeed of approximately 4mph
(7 km/h), the distance warning function warns
you if you rapidly approach avehicle in front.A n
intermittent warning ton ewill then sound, and
the · distance warning lamp will light up in
the instrument cluster.
XBrake immediately in order to increase the
distance from the vehicle in front.
or
XTake evasive action, provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause the system to display awarning.
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 aspeed of approximately 44 mph
(70 km/h), the distance warning function can
also react to stationary obstacles, such as stop-
ped or parked vehicles.
Autonomous braking function
If the driver does not react to the distance warn-
ing signal in acritical situation, Active Brake
Assist can assist the driver with the autonomous
braking function.
The autonomous braking function:
Rgives the driver more time to react to critical
driving situations
Rcan help the driver to avoid an accident or
Rreduces the effectsofana ccident
Vehicles without Distance Pilot DISTRONIC: the autonomous braking function is available in
the following speed ranges:
R4-65m ph (7-105 km/h) for moving objects
R4-31mph (7-50km/h)for stationary
objects
Vehicles with Distance Pilot DISTRONIC: the
autonomous braking function is available in the
following speedr anges:
R4-124 mph (7 -200 km/h )for moving
objects
R4-31m ph (7-50km/h)for stationary
objects
Due to the nature of the system ,particularly
complicated but non-critical driving conditions
may als ocaus ethe Autonomou sBraking Func-
tion to intervene.
Situation-dependent braking assis-
tance
General information
iObservet he "Important safety notes" sec-
tion (Ypag e61).
With the help of the rada rsensor system ,Adap-
tive Brake Assist can detect obstacles that are in
the path of you rvehiclef or an extended period
of time.
If Adaptive Brake Assist detects arisk of colli-
sion with the vehicleinf ront, it calculatesthe
brake pressure necessary to avoi dacollision. If
you apply the brakes forcefully ,situation-
dependent braking assistance adapts to the sit-
uation and automatically increases the brake
pressure to adegreea ppropriate to the traffic
situation.
Situation-dependent braking assistance pro-

sensor technology to assess the traffic situa-
tion.
Situation-dependent braking assistance is capa-
ble of reacting to moving objects that have
alreadybeen detected as such at least once
over the period of observation, up to vehicle
speeds of around 155 mph (250 km/h).
Situation-dependent braking assistance can
also detect stationary objects, up to vehicle
speeds of around 44 mph (70 km/h).
XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally againi f:
Ryou release the brake pedal.
Rthere is no longer any danger ofacollision.
Rno obstacle is detected in front of your vehi-
cle.
Situation-dependent braking assistance is then
deactivated.
Important safety notes
iObserve the "Important safety notes" sec-
tion for driving safety systems (Ypage 61).
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rwhen cornering
As aresult, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist might:
Rintervene unnecessarily
Rnot intervene
There is arisk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Terminate the
intervention in anon-critical driving situation.
Due to the nature of the system, complex but
non-critical driving conditions may also cause
Active Brake Assist to intervene.
Even if Active Brake Assist is not available due to
am alfunction in the radar sensor system, the
brake system is still available with full brake
boosting effect and BAS.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-
tion (Ypage 61).
ESP
®monitors driving stability and traction,i .e.
power transmission between the tires and the
road surface.
If ESP
®detects that the vehicle is deviating from
the direction desired by the driver, one or more
wheels are braked to stabilize the vehicle. The
engine output is also modified to keep the vehi-
cle on the desired course within physical limits.
ESP
®assists the driver when pulling awayo n
wet or slippery roads. ESP®can also stabilize
the vehicle during braking.
ETS/4ETS (Electronic Traction System)
iObserve the "Important safety notes" sec-
tion (Ypage 61).
ETS traction control is part of ESP
®.Onv ehicles
with 4MATIC, 4ETS is part of ESP®.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
awaya nd accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is transfer-
red to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP
®.
