Protection of the environment
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 old vehicle to
dispose of it in an environmentally-responsible
manner in accordance with the European Union (EU) End of Life Vehicles Directive.
There is a network of return points and disas-
sembly plants available. You can return your
vehicle to these plants free of charge. This
makes a valuable contribution to the recycling
process and the conservation of resources.
For further information on recycling old vehi-
cles, recovery and the terms of the policy, visit
the Mercedes-Benz homepage. 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.
Have accessories retrofitted at a qualified
specialist workshop. 24

after a cold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly.
Hill start assist Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll. G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may roll away. There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
R you are pulling away on a level road or a
downhill gradient
R on vehicles with automatic transmission, the
transmission is in position N
R the parking brake is applied
R ESP ®
is malfunctioning ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
When pulling away again, the engine starts auto-
matically. The ECO start/stop function thereby
helps you to reduce the fuel consumption and
emissions of your vehicle.
Important safety notes G
WARNING
If the engine is switched off automatically and you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving. There is a risk of accident and injury. If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.
General notes :
ECO start/stop display
The ECO start/stop function is activated when-
ever you start the engine using the key or the
Start/Stop button.
If the ¤ symbol is shown in green in the mul-
tifunction display, the ECO start/stop function
switches the engine off automatically if the vehi- cle stops moving.
If the ECO start/stop function has been man-
ually deactivated (Y page 143) or a malfunction
has caused the system to be deactivated, the
¤ symbol is not displayed.
Automatic engine switch-off General notes
The ECO start/stop function is operational and
the ¤ symbol is displayed in green in the
multifunction display, if:
R the indicator lamp in the ECO button is lit
green
R the outside temperature is within the range
that is suitable for the system
R the engine is at normal operating temperature
R the set temperature for the vehicle interior
has been reached
R the battery is sufficiently charged
R the system detects that the windscreen is not
misted up when the air-conditioning system is switched on
R the bonnet is closed
R the driver's door is closed and the driver's
seat belt is fastened
If the conditions for automatic engine switch-off
are not all fulfilled, the ¤symbol is shown in
yellow. 142

Automatic drive program E Drive program
Eis characterised by the follow-
ing:
R comfort-oriented engine settings.
R optimal fuel consumption resulting from the
automatic transmission shifting up sooner.
R the vehicle pulling away more gently in
forward and reverse gears unless the accel-
erator pedal is depressed fully.
R increased sensitivity. This improves driving
stability on slippery road surfaces, for exam-
ple.
R the automatic transmission shifting up
sooner. This results in the vehicle being driven
at lower engine speeds and the wheels being less likely to spin. Automatic drive program S Drive program
Sis characterised by the follow-
ing:
R sporty engine settings.
R the automatic transmission shifting up later,
as a result of the later automatic transmission
shift points, the fuel consumption possibly
being higher.

ECO display assists you in achieving the most
economical driving style for the selected set-
tings and prevailing conditions. Consumption
can be significantly influenced by your driving
style.
The ECO display consists of three bars:
R Acceleration
Acceleration
R Constant Constant
R Coasting
Coasting
The percentage count is the mean value of the
three bar values. The three bars and the mean
value begin at the value of 50%. A higher per-
centage count indicates a more economical
driving style.
The ECO display does not indicate the actual fuel
consumption. A fixed percentage count in the
ECO display does not indicate a fixed consump- tion.
In addition to driving style, the consumption is
affected by many 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 in the ECO dis-
play.
The evaluation of your driving style takes the
following three categories into consideration:
R Acceleration Acceleration (evaluation of all acceleration
processes):
- the bar fills up: moderate acceleration,
especially at higher speeds
- the bar empties: sporty acceleration
R Constant Constant (assessment of driving behaviour
at all times):
- the bar fills up: constant speed and avoid-
ance of unnecessary acceleration and
deceleration
- the bar empties: fluctuations in speed
R Coasting Coasting (assessment of all deceleration
processes):
- the bar fills up: anticipatory driving, keep-
ing your distance and early release of the
accelerator. The vehicle can coast without
use of the brakes.
- the bar empties: frequent braking
i An economical driving style involves driving
at a moderate engine speed. To achieve a higher value in the categories
Acceleration
Acceleration andConstant Constant:
R observe the gearshift recommendation
R drive the vehicle in drive program E(vehi-
cles with automatic transmission)
i On long journeys at a constant speed, e.g.
on the motorway, only the bar for Constant
Constant
will change.
i The ECO display summarises the driving
characteristics from the start of the journey to
its completion. Therefore, there are dynamic
changes in the bars at the start of a journey.
During a prolonged driving time, these
changes are smaller. For more dynamic
changes, perform a manual reset.
Further information on the ECO display
(Y page 216). Brakes
Important safety notes G
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.
Downhill gradients Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by constantly applying light
pressure to the pedal. This results in excessive
and premature wear to the brake pads.
Change into a lower gear in good time on long
and steep downhill gradients.
Take particular note of this when driving a laden vehicle and when towing a trailer.
i This also applies if you have activated cruise
control, SPEEDTRONIC or DISTRONIC PLUS.
This will use the braking effect of the engine, so
less braking will be required to maintain vehicle
speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly. 160

tem or the tyre pressure monitor cannot func-
tion reliably. Only restart the tyre pressure loss
warning system or tyre pressure monitor when
the defective wheel has been replaced with a
new wheel.
Vehicles with a tyre pressure monitor: all fit-
ted wheels must be equipped with functioning
sensors. Wheel and tyre combinations
You can ask for information regarding permitted wheel-tyre combinations at a Mercedes-Benz
Service Centre.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres and wheels
which have been approved by Mercedes-Benz specifically for your vehicle.
These are specially adapted to the control
systems, such as ABS or ESP ®
and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when driving with a load, tyre dimension variations
could cause the tyres to come into contact
with the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tyres, wheels or
accessories other than those tested and
approved.
Further information about wheels, tyres and
approved combinations can be obtained from any qualified specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tyres. As a result, Mercedes-Benz cannot guarantee vehicle safety if retreaded
tyres are fitted. Do not fit used tyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and therisk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommended tyre pressures can be found
in the tyre pressure table on the fuel filler flap.
For further information on tyre pressure, see
(Y page 324). Check tyre pressures regularly
and only when the tyres are cold.
Notes on the vehicle equipment – always fit the
vehicle:
R with tyres of the same size across an axle
(left/right)
R with the same type of tyres at a given time
(summer tyres, winter tyres, MOExtended
tyres)
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics)" section
(Y page 306).
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop. Emergency spare wheel
