evant systems, e.g. the brake system. Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tires, wheels and
accessories that have been specifically
approved for your vehicle.
Genuine Mercedes-Benz parts are subject to

tion, strategically located parts delivery cen-
ters provide quick and reliable parts service.

Benz parts ( Ypage 348).

Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.

particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.

Useful information
iThis Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops ( Ypage 25).
Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise fog up.
To prevent the windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off ( Ypage 133).
iWhen the weather is warm, ventilate the
vehicle for a brief period. This will speed up the cooling process and the desired vehicle
interior temperature will be reached morequickly.
iThe integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants and odors. A clogged filter reduces the amount of air supplied to the vehicle
interior. For this reason, you should alwaysobserve the interval for replacing the filter, which is specified in the Maintenance
Booklet. As it depends on environmental
conditions, e.g. heavy air pollution, the
interval may be shorter than stated in the
Maintenance Booklet.
122Overview of climate control systems
Climate control

Drive sensibly – save fuel
Observe the following tips to save fuel:R The tires should always be inflated to the
recommended tire pressure.
R Remove unnecessary loads.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Observe the service intervals in the Main-
tenance Booklet or in the service interval
display. Have all the maintenance work car-
ried in accordance with Daimler AG regu-
lations.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and in hilly terrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs anddriving 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
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. All work
on the engine must be carried out only by
qualified and authorized Mercedes-Benz
technicians.
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
Example: ECO display
The ECO display provides feedback on how
economical your driving characteristics are.
The ECO display assists you in achieving the
most economical driving style for the selec-
ted settings and prevailing conditions. Your
driving style can significantly influence the
vehicle's consumption.
The ECO display consists of three bars: R
Acceleration
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 percent-
age 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
consumption.
