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 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 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

Function
Starting at aspeedofa pproximately 4mph
(7 km/h), th edistanc ewarning function warns
you ifyou rapid ly approachav ehicle in front. An

XTakee vasive action,p rovide ditiss afe todo

Due to th enature of th esystem, particularly
co mpli cated but non-critical driving conditions
may also caus ethe system to displayaw arning.
Witht hehelp of th eradar sensor system, the
dist ancewarning function can detect obstacles
that are inthep athofy our veh iclefor an exten-
ded period of time.
Up to aspeedofa pproximately 44 mph
(70 km/ h),t he distance warnin gfunction 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
Assis tcan assist with the autonomous braking
function.
If the autonomous brakin gfunction requires a
particularly high brakin gforce, preventative
passenger protection measures (PRE-SAFE
®)
are activated simultaneously.
Vehicles without Distance Assist
DISTRONIC: the autonomous brakin gfunction
is available in the following speed ranges:
R4-65m ph (7-105 km/ h)for moving objects
R4-31m ph (7-50km/h)for stationary
objects
Vehicles with Distance Assist 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. If the autonomous braking function requires a
particularly high braking force, preventative
passenger protection measures (PRE-SAFE
®)
are activated simultaneousl y(Ypage53).
Adaptive Brake Assist
General information
iObservet he "Important safety notes" sec-
tion (Ypag e56).
With the help of adaptive Brake Assist, the dis-
tance warning signalc an 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
braking force necessary to avoi dacollision. If
you apply the brakes forcefully ,adaptive Brake
Assist wil lautomatically increas ethe braking
force to alevels uitabl efor the traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardouss ituations at speeds above
4m ph (7 km/h) .Itusesrada rsensor technology
to assess the traffic situation.
Up to aspeedofa pproximately 155 mph
(250 km/h) ,adaptive Brake Assist is capable of
reacting to moving objects that have already
been detected as such at least once over the
period of observation.
Up to aspeedofa pproximately 44 mph
(70 km/h), adaptive Brake Assist reacts to sta-
tionary obstacles.
If adaptive Brake Assist demands particularly
high braking force, preventative passenger pro-
tection measures (PRE-SAFE
®)a re activated
simultaneousl y(Ypage53).
XKeep the brake pedald epressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes wil lwork normally again if:
Ryou release the brake pedal.
Rthere is no longera ny dangerofacollision.
Rno obstacle is detected in front of you rvehi-

Adaptive Brake Assist is then deactivated.
