Environmental protection
General notes
H
Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
Our objectives are to use the natural resour-
ces which form the basis of our existence on
this planet sparingly and in a manner which
takes the requirements of both nature and
humanity into consideration.
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 tyre wear depend on
the following factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors. Therefore,
please bear the following in mind:
Operating conditions:
R avoid short trips, as these increase fuel
consumption.
R observe the correct tyre pressure.
R do not carry any unnecessary weight in the
vehicle.
R remove the roof rack once you no longer
need it.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R all maintenance work should be 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 and
braking. 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 monitor the vehicle's fuel consumption. Returning an end-of-life vehicle
EU countries only:
Mercedes-Benz will take back your end-of-life
vehicle for environmentally-friendly disposal in
accordance with the European Union (EU) End-
Of-Life Vehicles Directive.
A network of vehicle take-back points and dis-
mantlers has been established for you to return
your vehicle. You can leave it at any of these
points free of charge. This makes an important
contribution to closing the recycling circle and
conserving resources.
For further information about the recycling and
disposal of end-of-life, and the take-back con-
ditions, please visit the national Mercedes-Benz
website for your country. Genuine Mercedes-Benz parts
H
Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war- ranty applies as for new parts.
! Airbags and seat belt tensioners, 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 dashboard
R instrument cluster
R centre 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. 26

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 before the intervention
of PRE-SAFE ®
PLUS.
PRE-SAFE ®
PLUS does not intervene:
R if the vehicle is reversing
R when the vehicle is towing a trailer and there
is a risk of a rear-end collision
When driving, or when parking or exiting a park- ing space with assistance from Active Parking
Assist, 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:
R if the radar sensor system detects that a
head-on collision is imminent, the seat belts
are pre-tensioned
R if the radar sensor system detects that a rear-
end collision is imminent:
- the rear hazard warning lamps are activa-
ted and flash at a higher frequency
- 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-
celled:
R if the accelerator pedal is depressed when a
gear is engaged
R if the risk of a collision passes or is no longer
detected
R if DISTRONIC PLUS 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:
R the hazard lamps are switched on
R the emergency lighting is switched on
R the vehicle doors are unlocked
R the front side windows are lowered
R vehicles with the memory function: the elec-
trically adjustable steering wheel is raised
R the engine is switched off and the fuel supply
is cut off
R vehicles with the Mercedes-Benz emergency
call system: automatic emergency call Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat. Children are generally better protected there.
If a child younger than twelve years old and
under 1.50 min height is travelling in the vehi-
cle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
R be sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions.
R be sure to observe the instructions and safety
notes on the automatic front-passenger front airbag deactivation system (Y page 49).56

the engine speed does not reach the red area
of the rev counter.
X To shift down: pull steering wheel gearshift
paddle :.
The automatic transmission shifts down to
the next gear.
Automatic downshifting occurs when coast-
ing.
If the engine exceeds the maximum engine
speed when shifting down, the automatic
transmission protects against engine damage
by not shifting down.
Gearshift recommendation The gearshift recommendation assists you in
adopting a fuel-efficient driving style. The rec-
ommended gear is shown on the multifunction
display.
X When gearshift recommendation :is shown
on the multifunction display of the instrument
cluster, shift to recommended gear ;.
Protection against reaching the over-
revving range (Mercedes-AMG vehicles) !
The automatic transmission does not shift
up automatically even when the engine limit-
ing speed for the current gear is reached.
When the engine limiting speed is reached, the fuel supply is cut to prevent the engine
from overrevving. Always make sure that the
engine speed does not reach the red area of
the rev counter. There is otherwise a risk of
engine damage. Before the engine speed reaches the red area,
an upshift indicator will be shown on the multi-
function display.
X When message :appears on the multifunc-
tion display, pull the right-hand steering
wheel gearshift paddle.
Kickdown X
For maximum acceleration, depress the
accelerator pedal beyond the pressure point.
The automatic transmission shifts to a lower
gear depending on the engine speed.
X Shift back up once the desired speed is
reached.
During kickdown, you cannot shift gears using
the steering wheel gearshift paddles.
If you apply full throttle, the automatic trans-
mission shifts up to the next gear when the
maximum engine speed is reached. This pre-
vents the engine from overrevving.
Mercedes-AMG vehicles: kickdown is possible
only in the temporary setting. 160

If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is a risk of
fire and explosion.
Always touch the vehicle body before opening the fuel filler flap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up.
Do not get back into the vehicle during the refu-
elling process, otherwise electrostatic charge
could build up again. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel can
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not switch on the ignition if you accidentally refuel with the wrong fuel.
Otherwise, fuel can enter the fuel system. Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. The repair costs are high. Notify a
qualified specialist workshop and have the
fuel tank and fuel lines drained completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
! Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system could otherwise be blocked by particles fromthe fuel can.
If you overfill the fuel tank, some fuel may spray
out when you remove the fuel pump nozzle.

cluster flashes
When the vehicle has been braked to a stand-
still, the electric parking brake is applied. Parking up the vehicle
If you leave the vehicle parked up for longer than
four weeks, the battery may be damaged by
exhaustive discharging.
If you leave the vehicle parked up for longer than
six weeks, it may suffer from lack of use.
X Contact a qualified specialist workshop and
seek advice.
i You can obtain information on trickle charg-
ers from a qualified specialist workshop.

Important safety notes G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving.
Drive sensibly – save fuel Observe the following tips to save fuel:
X The tyres should always be inflated to the rec-
ommended tyre pressure.
X Remove unnecessary loads.
X Remove roof racks when they are not needed.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the Ser-
vice Booklet or by the service interval display.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic, on short jour- neys and in hilly terrain. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists you in achieving the most economical driving style
for the selected settings and prevailing condi-
tions. Consumption can be significantly influ-
enced by your driving style. :

display. In addition, warning lamp
8on the
instrument cluster lights up (Y page 286).
The ECO display consists of three sections, with an inner and outer area. The sections corre-
spond to the following three categories: :
Acceleration
(evaluation of all accel-
eration processes):
R The outer area fills up and the inner
area lights up green: moderate
acceleration, especially at higher
speeds.
R The outer area empties and the
inner area is grey: sporty acceler-
ation. ;
Coasting
(evaluation of all decelera-
tion processes):
R The outer area fills up and the inner
area lights up green: anticipatory
driving, keeping your distance and early release of the accelerator.
The vehicle can coast without use
of the brakes.
R The outer area empties and the
inner area is grey: frequent heavy
braking. =
Constant
(continuous evaluation
over the entire journey):
R The outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and decelera-
tion.
R The outer area empties and the
inner area is grey: fluctuations in
speed. The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on the driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up. The ECO display does not indicate the actual fuel
consumption. The additionally achieved range
displayed under Bonus fr. start
Bonus fr. start does not
indicate a fixed consumption reduction.
In addition to driving style, the actual consump- tion is affected by other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included on the ECO dis-
play.
An economical driving style involves driving at a moderate engine speed.
To achieve a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation.
R drive the vehicle in drive program E
On long journeys at a constant speed, e.g. on the motorway, only the outer area for "Constant"
will change.
The ECO display summarises the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of a journey. During
a prolonged driving time, these changes are
smaller. For more marked changes, perform a
manual reset (Y page 234).

WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface. Driving tips

R a system fault occurs
R the power supply is insufficient
If a malfunction occurs, the transmission may
also be shifted to position jautomatically. AIR BODY CONTROL
General notes AIR BODY CONTROL is an air suspension system
with variable damping for improved driving com-
fort. All-round level control ensures the best
possible suspension and constant ground clear- ance, even with a laden vehicle. When you driveat speed, the vehicle is lowered automatically to improve driving safety and to reduce fuel con-
sumption. You also have the option of manually
adjusting the vehicle level. AIR BODY CONTROL
consists of level setting, level control and the
ADS Adaptive Damping System.
The vehicle level can be set using the DYNAMIC SELECT switch (Y page 152) or the level button
(Y page 188). The setting always corresponds
to the last function selected.
Important safety notes G
WARNING
People's limbs may become trapped if they
are located underneath the vehicle or
between the vehicle body and the tyres when the vehicle is lowering. There is a danger of
injury.
When lowering the vehicle, make sure no one
is underneath the vehicle or in the immediate vicinity of the wheel arches.
i If one of the doors is open, the vehicle is not
lowered. Driving systems

The vehicle/trailer combination could become
unstable.
The vehicle/trailer combination could also
become unstable if the noseweight used is lower
than the minimum permissible noseweight.
To avoid hazardous situations:
R make sure to check the noseweight before
each journey
R use a noseweight as close as possible to the
maximum noseweight
R do not exceed the maximum permissible
noseweight
R do not use a noseweight lower than the min-
imum noseweight
Make sure that the following values are not
exceeded:
R the permissible noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
The applicable permissible values, which must
not be exceeded, can be found:
R in your vehicle documents
R on the type plates for the trailer
R on the vehicle identification plate
If the values differ, the lowest value applies.
You will find permissible trailer loads under
"Technical data" (Y page 380).
When reversing the towing vehicle, make sure
there is nobody between the trailer and the vehi- cle.
Couple and uncouple the trailer carefully. If you
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is affected more by strong crosswinds R
demands more sensitive steering
R has a larger turning circle
This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain a safe distance. Drive carefully.
When towing a trailer, always adjust your speed to the current road and weather conditions. Do
not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on towing a trailer
General notes When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for a maxi-
mum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 359).
You will find permissible trailer loads under
"Technical data" (Y page 380).
Driving tips Observe the information on ESP
®
trailer stabili-
sation (Y page 76).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the maximum per-
missible speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing a trailer. See the "Technical data"
section to find out whether this applies to your
vehicle (Y page 381). In the event of increased
rear axle load, the car/trailer combination may
not exceed a maximum speed of 100 km/ hfor
reasons concerning the operating permit. This
also applies in countries in which the maximum
permissible speed for car/trailer combinations
is greater than 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer and the vehicle will consume
more fuel.
Shift to a lower gear in good time on long and
steep downhill gradients.
This also applies in the case of:
R activated DISTRONIC PLUS
