It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the temperature that has
been set.
Coupé: the residual heat function only works
optimally when the side window sand pano-
rama sliding sunroo fare closed.

i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key is removed. The vehicle is then
ventilated for 30 minutes to dry the air-
conditioning system.

Important safety notes G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefor eswitch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. agarage. G
WARNING
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 alonger
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 aqualified specialist
workshop, e.g. aMercedes-BenzS ervice
Centre. Operating thec

You cannot use the auxiliary ventilation to
cool the vehicle interior to atemperature
lower than the outsid etemperature.
Befor eswitchin gon 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 climat econtrol is being
controlled manually. Optimum comfor tcan
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 deactivate dusing the remote control
or the button on the centr econsole.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y page 229).

You may use two additional remot econtrols
for your vehicle. For further information, con-
sult aqualified specialist workshop ,e.g.a
Mercedes-Ben zService Centre.
The remote control has amaximum range of
approximately 300 metres. This range is
reduced by:
R sources of radio interference
R solid objectsb etween the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
i The optimum range can be achieved if you

Problem Possible causes/consequences and
M Solutions
Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or in amechanical
componentoft he engine management system.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop, e.g. aMercedes-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 283). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X
At coolant temperatures under 120 †, drive on to the nearest
qualified specialist workshop, e.g. to aMercedes-Benz Service
Centre.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Manual transmission
Gear lever
Gear lever
!
Only engage gear when the clutch pedal
is depressed.
! When shifting between 5thand 6thgear,
you should always push the gear lever all the way to the right. Otherwise, you could
shift unintentionally into
3rdor4th gear
and damage the transmission.
If you shift down at too high aspeed (trans-
mission braking), this can cause the engine
to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients.
There is otherwise arisk of damaging the
clutch.
! On long and steep downhill gradients,
especially if the vehicle is laden or towing
at railer, you must shift into gear 1, 2or3
in good time. This uses the engine's braking
effect.T his relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. Manual transmission
