Protecting the environment
General notes
H
Environmental note
The pollutant emission of your vehicle is
directly related to the vehicle's operation.
You can make a contribution to environmental protection by operating your vehicle in an
environmentally responsible manner. To do
this, observe the following recommendations
on operating conditions and your personal
driving style.
Operating conditions:
R Make sure that the tire pressure is correct.
R Do not carry any unnecessary weight with
you (e.g. a roof rack which is no longer
required).
R Observe the service intervals. A regularly
serviced vehicle will contribute to environ-
mental protection.
R Always have maintenance work 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 while station-
ary.
R Drive carefully and maintain a sufficient dis-
tance to other vehicles.
R Avoid frequent, sudden acceleration and
braking.
R Shift gears in good time and use each gear
only up to 00C3of its maximum engine speed.
R Switch off the engine in stationary traffic,
e.g. use the ECO start/stop function.
R Drive in a fuel-saving manner. Pay attention
to the ECO display for a fuel-efficient driving
style. Environmental concerns and recom-
mendations
Wherever the Operator's Manual requires you to
dispose of materials, first try to recycle or re-use them. Observe the relevant environmental rules
and regulations when disposing of materials. In
this way you will help to protect the environ-
ment. Genuine Mercedes-Benz parts
H
Environmental 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:
R doors
R door pillars
R door sills
R seats
R cockpit
R instrument cluster
R center 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
systems, e.g. the brake system. Use only genu-
ine Mercedes-Benz parts or parts of equal qual-
ity. Only use tires, wheels and accessories that
have been specifically approved for your vehi-
cle.
Genuine Mercedes-Benz parts are subject to
strict quality control. Every part has been spe-
cifically developed, manufactured or selected
for and adapted to Mercedes-Benz vehicles.
Therefore, only genuine Mercedes-Benz parts
should be used. 24
Genuine Mercedes-Benz partsIntroduction

X
Connect the cable provided in the trunk to the
trickle charger.
X Connect the trickle charger to 12 V socket 0043.
Consult the manufacturer's operating instruc- tions on how to do so.
The trunk lid can be closed, even if a trickle
charger is connected. Make sure that the con-
nector for both the connector cables is outside
of the vehicle.
The connector can then separate if the vehicle is moved, even if you forget to disconnect the con-
nector cables. This prevents damaging the
cables and the trickle charger.
A trickle charger connected to 12 V socket 0043
only maintains the current charge level of the
vehicle's electrical system battery. If the vehi-
cle's electrical system battery is discharged, it
needs to be charged with a battery charger. Driving tips
General driving tips
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. G
WARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. 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:
X The tires should always be inflated to the rec-
ommended tire pressure.
X Remove unnecessary loads.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all service and maintenance work car-
ried out at the specified intervals.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic and in hilly ter- rain.
Drinking and driving G
WARNING
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.
Emission control G
DANGER
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases is hazardous to health
and can result in poisoning. There is a risk of
fatal injury. Therefore, never leave the engine Driving tips
131Driving and parking
Z

running an enclosed space without adequate
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.
You can obtain current information concerning
the servicing of your vehicle at any time from a
qualified specialist workshop. This could be an
overview of the maintenance work or any addi-
tional maintenance work, for example. Braking
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.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting to a
lower gear in good time. This allows you to
take advantage of the engine's braking effect.
This helps you to avoid overheating the
brakes and wearing them out excessively.
When you take advantage of engine braking, a drive wheel may not turn for some time, e.g.
on a slippery road surface. This could cause damage to the drive train. This type of damage
is not covered by the Mercedes-Benz war-
ranty.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately. Drive on for a short while. This allows the airflow to
cool the brakes more quickly.
Wet roads If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance.132
