Useful information
i This Owner's Manual describes all models,
series and optional equipment for your vehi-
cle that were available at the time of going to
press. National variations are possible. Note
that your vehicle may not be equipped with all
of the functions described. This is also the
case for systems and functions relevant to
safety.
i Read the information on qualified specialist
workshops: (Y page 28). Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activate the windscreen demisting function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
For vehicles with a combustion engine, the
"Cooling with air dehumidification" function is
only available when the engine is running. For
hybrid vehicles, the "Cooling with air dehumidi-
fication" function is also available via the elec-
tric refrigerant compressor when the engine is
not running. Optimum climate control is only
achieved with the side windows and roof closed.
The "Residual heat" function can only be activa-
ted or deactivated with the ignition switched off (Y page 146).
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the "Convenience
opening" feature (Y page 99).
This will speed up the cooling process and the
desired interior temperature will be reached
more quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odours. A clogged filter reduces the amount of air supplied to the vehicle interior.
For this reason, you should always observe
the interval for replacing the filter, which is
specified in the Service Booklet. As this
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i Vehicles with AIR-BALANCE package:
in
addition to ionisation, the vehicle has an air
filter with anti-allergenic properties that con-
tribute to improved air filtration.
i Under certain environmental conditions, the
residual heat function may be activated auto-
matically an hour after the key has been
removed in order to dry the automatic climate control. The vehicle is then ventilated for 30
minutes. Overview of climate control systems
135Climate control

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. 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 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.
! 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.
! 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.
Do not get into the vehicle again during the refu-
elling process. Otherwise, electrostatic charge
could build up again.
If you overfill the fuel tank, some fuel may spray out when you remove the fuel pump nozzle.
Further information on fuel and fuel quality
(Y page 436). Refuelling
General notes Observe the important safety notes
(Y
page 175).
PLUG-IN HYBRID vehicles: pressure in the fuel
tank must be released before refuelling.
Except PLUG-IN HYBRID vehicles: if you
unlock/lock the vehicle from the outside, the
fuel filler flap also unlocks/locks.
The position of the 8fuel filler cap is dis-
played in the instrument cluster. The arrow next to the filling pump indicates the side of the vehi-
cle.

WARNING
DISTRONIC PLUS brakes your vehicle with up to 50% of the maximum possible deceleration.
If this deceleration is not sufficient,
DISTRONIC PLUS alerts you with a visual and
acoustic warning. There is a risk of an acci-
dent.
Apply the brakes yourself in these situations
and try to take evasive action.
! When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash
If you fail to adapt your driving style, DISTRONIC PLUS can neither reduce the risk of an accident
nor override the laws of physics. DISTRONIC
PLUS cannot take road and weather conditions
or traffic conditions into account. DISTRONIC
PLUS is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in lane.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line.
In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections, for
example, in multi-storey car parks
If DISTRONIC PLUS no longer detects a vehicle
in front, it may unexpectedly accelerate to the
speed stored. This speed can:
R be too high for a filter lane or a slip road
R be so high in the right lane that you pass vehi-
cles driving on the left
R be so high in the left lane that you pass vehi-
cles driving on the right
If there is a change of drivers, advise the new
driver of the speed stored.

Resetting the ASSYST PLUS service
interval display !
If the ASSYST PLUS service interval display
has been inadvertently reset, this setting can be corrected at a qualified specialist work-
shop.
Have service work carried out as described in the Service Booklet. This may otherwise lead
to increased wear and damage to the major
assemblies or the vehicle.
A qualified specialist workshop, e.g. a
Mercedes-Benz Dealership, will reset the
ASSYST PLUS service interval display after the
service work has been carried out. You can also
obtain further information on maintenance
work, for example.
Special service requirements The prescribed service interval is based on nor-
mal operation of the vehicle. Service work will
need to be performed more often if the vehicle is
operated under arduous conditions or increased loads, for example:
R regular city driving with frequent intermediate
stops
R if the vehicle is primarily used to travel short
distances
R for frequent operation in mountainous terrain
or on poor road surfaces
R if the engine is often left idling for long periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil filter changed more frequently. The tyres must be
checked more frequently if the vehicle is oper-
ated under increased loads. Further informationcan be obtained at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service Centre.
Driving abroad An extensive Mercedes-Benz Service network is
also available in other countries. You can obtain further information from any Mercedes-Benz
Service Centre. Care
