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.
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
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 malfunctions in safety-relevant

Driving tips
General notes
Important safety notes
GWARNING
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.
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the country
in which you are driving. Some jurisdictions pro-
hibit the driver from using a mobile phone while
driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers a
distance of 44 ft (approximately 14 m)per sec-
ond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof racks when they are not needed.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work carried out as
indicated by the service intervals in the Main-
tenance Booklet or by the service interval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Driving tips143

Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications. Always have
work on the engine carried out at a qualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Benz Center for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop.
The engine settings must not be changed under any circumstances. Furthermore, all specific
service work must be carried out at regular
intervals and in accordance with the Mercedes-
Benz service requirements. Details can be found in the Maintenance Booklet.
ECO display
The ECO display provides feedback on how eco-
nomical your driving characteristics are. The
ECO display assists you in achieving the most
economical driving style for the selected set-
tings and prevailing conditions. Your driving
style can significantly influence the vehicle's
consumption.
The ECO display consists of three bars:
RAcceleration
RConstant
RCoasting
The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%. A higher percentage
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.
Apart from driving style, consumption is
dependent on many factors such as, e.g.:
Rload
Rtire pressure
Rcold start
Rchoice of route
Relectrical consumers switched on
These factors are not included in the ECO dis-
play.
The evaluation of your driving style is carried out
using the following three categories:
RAcceleration(evaluation of all acceleration
processes):
-The bar fills up: moderate acceleration,
especially at higher speeds
-The bar empties: sporty acceleration
RConstant(assessment of driving behavior at
all times):
-The bar fills up: constant speed and avoid-
ance of unnecessary acceleration and
deceleration
-The bar empties: fluctuations in speed
RCoasting(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
iAn economical driving style specially
requires driving at moderate engine speeds.
To achieve a higher value in the categories
Acceleration
and Constant:
Robserve the gearshift recommendations.
Rdrive in drive program E.
iOn long journeys at a constant speed, e.g.
on the highway, only the bar for Constantwill
change.
iThe ECO display summarizes the driving
characteristics from the start of the journey to
its completion. For this reason, the bars
