M
MSolutions The rear window heating
has switched off prema-
turely or cannot be acti-
vated. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading lamps,
interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window heating
can be activated again. Switching air-recirculation mode
on/off
General notes You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle from
outside. The air already inside the vehicle will
then be recirculated.
If you activate air-recirculation mode, the win-
dows can mist up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows misting up.

between the side window and window frame.
There is a risk of injury.
When opening, make sure that nobody is
touching the side window. If someone
becomes trapped, immediately press
the W switch in the door to stop the move-
ment of the side windows. To continue closing
the side window, pull on the Wswitch.

General notes It is possible to make use of the residual heat of
the engine to continue heating the vehicle for
approximately 30 minutes after the engine has
been switched off. The heating time depends on
the set interior temperature.
The "residual heat" function only functions opti- mally with the side windows closed.

Important safety notes G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
The auxiliary heating and the exhaust gas dis-
charge location can be found in front of the right- hand front wheel.
! Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle a maximum of two times, drive for a longer distance. 132
Operating the climate control systemClimate control

These notes must be observed under all cir-
cumstances. You could otherwise damage
the engine, the electronics or the transmis-
sion.
If you must drive on stretches of road on which
water has collected, please bear in mind that:
R in the case of standing water, the water level
must be no higher than the lower edge of the vehicle body
R you should drive no faster than walking pace Winter driving
G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden acceleration,
steering and braking manoeuvres. If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: shift
to neutral.
X Vehicles with automatic transmission:
shift the transmission to position
N.
X Try to bring the vehicle under control by using
corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in wooded areas or on bridges. The vehicle could
skid if you fail to adapt your driving style. Always
adapt your driving style and drive at a speed to
suit the prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

! Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle a maximum of two times, drive for a longer distance.
Only vehicles with auxiliary heating have this
function.
In the Heating Heating submenu, you can select a
stored departure time or change a departure
time.
The auxiliary heating timer function calculates
the switch-on time according to the outside
temperature so that the vehicle is preheated by the departure time. When the departure time isreached, the auxiliary heating continues to heat
for a further five minutes and then switches off. The auxiliary heating adopts the THERMATIC orTHERMOTRONIC temperature setting.
You can switch off the auxiliary heating by using
the remote control or the auxiliary heating but-
ton on the centre console.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
