Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. Otherwise, the windows could
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
The air-conditioning system or THERMOTRONIC
automatic climate control regulates the temper- ature and the humidity of the vehicle interior andfilters undesirable substances from the air.
The air-conditioning system or THERMOTRONIC automatic climate control can only be operatedwhen the engine is running. Optimum operationis only achieved with the side windows and pan-
orama sliding sunroof closed.
The residual heat function can only be activated or deactivated with the ignition switched off
(Y page 126).
Always keep the ventilation flaps behind the
side panelling clear (Y page 113). Otherwise the
vehicle will not be ventilated correctly.
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 90). This will speed up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. With THERMOTRONIC automatic
climate control, gaseous pollutants and
odours will also be reduced. 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 Book-
let. As this depends on environmental condi-
tions, e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet.
i Vehicles with auxiliary heating:
Under
certain environmental conditions, the resid-
ual heat function may be activated automati-
cally an hour after the ignition key has been
removed in order to dry the automatic climate
control. The blue LED on the rocker switch in the centre console lights up when the active
function to dry the automatic climate control is on. The vehicle is then ventilated for
30 minutes.
Vehicles without auxiliary heating: Under
certain environmental conditions, the resid-
ual heat function may be activated automati-
cally an hour after the ignition 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
117Climate control
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren.
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 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.
! 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.
! 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 back into the vehicle 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.

Do not use Distance Pilot DISTRONIC:
R in road and traffic conditions that 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 in poor visibility, e.g. due to fog, heavy rain or
snow.
Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can be
impaired in the following situations:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, e.g. in multi-storey
car parks
If Distance Pilot DISTRONIC no longer detects a vehicle in front, Distance Pilot DISTRONIC 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 on the right lane that you pass
vehicles driving in the left lane
R be so high in the left lane that you pass vehi-
cles driving in the right lane
If a new driver takes over, 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 Service Centre, 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 intermedi-
ate stops
R If the vehicle is primarily used to travel short
distances
R For frequent use in mountainous terrain or on
poor road surfaces
R If the engine is often left idling for long periods
R In particularly dusty conditions, or if air-recir-
culation mode is frequently used.
In these or similar operating conditions, have
the interior filter, engine air cleaner, engine oil
and oil filter, for example, changed more fre-
quently. The tyres must be checked more fre-
quently if the vehicle is operated under
increased loads. Further information can be
obtained at a qualified specialist workshop, e.g.
a Mercedes-Benz Service Centre.

Additives
!
Do not use any additives with the engine oil.
This could damage the engine. Brake fluid
G
WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to a heavy load. This would impair brak- ing efficiency. There is a risk of an accident.
Have the brake fluid renewed at the prescri-
bed intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
(Y page 327).
The brake fluid change intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB-Freigabe or MB-Approval
331.0.
