Selecting the switch-on time for the
auxiliary heating* This function is only available if the vehicle
has an auxiliary heating system.
The
Auxiliary

heat. function allows you to
select three switch-on times. You can set the
exact switch-on time using the other func-
tions in the Heater submenu.
The auxiliary heating adopts the Thermatic or
4-zone Thermotronic* temperature setting.
The minimum and maximum temperature set-
tings for the auxiliary heating are 20 † and
24 † respectively.
You can switch off the auxiliary heating by
using the remote control or the auxiliary heat-
ing button on the centre console.
The auxiliary heating is switched off automat-
ically after 50 minutes. This time can be
changed. To do this, visit a qualified specialist workshop, e.g. a Mercedes-Benz Service
Centre. G
Risk of fire and poisoning
The operation of the auxiliary heating pro-
duces hot, toxic exhaust fumes. The fuel
vapours produced during refuelling could
ignite on the hot exhaust system.
Do not switch on the auxiliary heating at
filling stations or in enclosed spaces, for
instance,

a garage, if there is no air extrac-
tion system.
You could otherwise endanger yourself and
others.
The Auxiliary heat. function can be called
up directly.

The auxiliary heating/ventilation is auto-
matically deactivated after about 30
minutes, or when:
R the ignition is switched on
R the battery voltage drops Auxiliary heating/ventilation*
G
Risk of poisoning
Exhaust fumes are produced when the aux-
iliary 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 system, 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 stations
or when your vehicle is being refuelled. You
must therefore switch off the auxiliary heat-
ing at filling stations.
The auxiliary heating heats the air in the vehi-
cle interior to a temperature between 20 °C and 24 °C without using the heat of the run-
ning engine. The auxiliary heating is operated
using fuel directly from the vehicle's fuel tank.
For this reason, the tank content 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 automatically switch over
from ventilation mode to heating mode or
from heating mode to ventilation mode.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before activating
X
Set the temperature to a value between
20 † and 24 †.
The auxiliary heating/ventilation can be acti-
vated even when the air conditioning is being
controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic mode. Set the desired temperature
within this range. If a higher temperature is
set, the vehicle is heated to 24 †. If a lower
temperature is set, the vehicle is heated to
20 †. Activating or deactivating the auxiliary
heating/ventilation The auxiliary heating/ventilation can be acti-
vated or deactivated via 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 128).

Remote control
Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For further information, con-
sult a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. The remote control has a maximum range of
approximately 300 metres. This range may be
reduced by:
R
sources of radio interference
R solid objects between 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
hold the remote control vertically, pointing
upwards when you press one of the but-
tons.
i A battery symbol appears in the display
when the batteries in the remote control
are low. Replace the remote control bat-
teries (Y page 270).
i More information about the auxiliary
heating can be found in the "Practical
advice" section ( Y page 264).1

Risk of injury
Never leave children unsupervised in the
vehicle. They could operate the sliding/tilt-
ing sunroof and injure themselves. Always
take the key with you when leaving the
vehicle, even if you only leave it for a short
time. G
Risk of injury
Make sure that nobody can become trap-
ped when you are opening and closing the
sliding/tilting sunroof. If danger threatens,
release the switch and push it briefly in any
direction to stop the sliding/tilting sunroof. G
Risk of injury
The glass in the sliding/tilting sunroof
could break in an accident. If you are not
wearing a seat belt, there is a risk that you
could be thrown through the opening in the
event of the vehicle overturning. Therefore,
always wear a seat belt to reduce the risk
of injuries. !
Only open the sliding/tilting sunroof if it
is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding/tilting sunroof. The seals could oth-
erwise be damaged.
i Resonance noises can occur in addition
to the usual airflow noises when the slid-
ing/tilting sunroof is open. They are caused
by minor pressure fluctuations in the vehi-
cle interior.
Change the position of the sliding/tilting
sunroof or open a side window slightly to
reduce or eliminate these noises.
i It is also possible to open and close the
sliding/tilting sunroof from the outside
using the "Summer opening" ( Y page 100)
and "Convenience closing" ( Y page 100)
features respectively. Controls
