Important safety notes G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts of
the vehicle may become very hot, and highly
inflammable material such as fuels could be
ignited. Operating the auxiliary heating is thus
prohibited at filling station sorwhen your vehi-
cle is being refuelled. You must therefore
switch off the auxiliary heating at filling sta-
tions.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for a longer
distance.
i Switch on the auxiliary heating regularly,
e.g. for about ten minutes every month. The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated directly using the
vehicle's fuel. For this reason, the tank con-
tent must be at least at reserve fuel level to
ensure that the auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode.
The auxiliary heating switches off automati-
cally after 50 minutes. This time limit can be
altered. To do this, visit a qualified specialist
workshop, e.g. a Mercedes-Ben
zService
Centre.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before switching on X
Turn the key to position 2in the ignition
lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when the climate control is being
controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic mode. Set the temperature to 22 †.
The auxiliary heating/ventilation can be acti-
vated or deactivated using the remote control
or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y page 210). Operating the climate control system

Problem Possible causes/consequences and
M Solutions
Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist
workshop, e.g. a Mercedes-Benz Service Centre.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 268). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X At coolant temperatures under 120 †, drive on to the nearest
qualified specialist workshop e.g. to a Mercedes-Benz Service
Centre.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Automatic transmission
Important safety notes
G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you to lose control of your vehicle and cause an
accident. Automatic transmission

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
available at the time of publicatio nofthe
Owner's Manual. Country-specific differen-
ces are possible. Please note that your
vehicle may not be equipped with all fea-
tures described. This also applies to safety-
relevant systems and functions. Important safety notes
You will find an illustration of the instrument
cluster in the "At a glance" section
(Y page 26). G
Risk of accident
Only use the on-board computer when road
and traffic conditions permit. You would oth-
erwise be distracted and unable to concen-
trate properly on driving, and could cause an
accident. G
Risk of accident
If the instrument cluster or multifunction dis-
play fails, no messages can be displayed.
This means that you will not see information
about the driving situation, such as the speed,
outside temperature, warning/indicator
lamps, display messages or system failures.
Handling characteristics may be affected.
Adapt your driving style and speed accord-
ingly.
Immediately consult a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Ben zrecommends that
you use a Mercedes-Benz Service Centre for
this purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist workshop. G
Risk of accident
The on-board computer only records and dis-
plays malfunctions and warnings from certain systems. For this reason, you should always
make sure that your vehicle is safe to use. You
could otherwise cause an acciden
tby driving
an unsafe vehicle. G
Risk of accident and injury
The operating safety of your vehicle could be
jeopardised if maintenance wor kis carried
out incorrectly. As aresult, you could lose
control of the vehicle and cause an accident.
In addition, the safety systems may no longer
be able to protec tyou or others as they are
designed to do.
Always have maintenance work carried out at
a qualified specialist workshop. The qualified
specialist workshop must have the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop. Displays and operation
Coolant temperature gauge
The coolant temperature gauge is in the
instrument cluster on the left-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †.
The coolant temperature may rise to the top
end of the scale at high outside temperatures
and on long uphill stretches. Rev counter
The red band in the rev counter indicates the
engine's overrevving range.
! Do not drive in the overrevving range.
Doing so will damage the engine.
The fuel supply is interrupted to protec tthe
engine when the red band is reached. 194
