ary vehicle for up to 30 minutes after the
engine has been switched off
.The heating
time depends on the coolant temperature and
on the interior temperature that has been set.
i The blower will run at a low speed regard-
less of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated.
X Turn the key to position 0(Ypage 143) in
the ignition lock or remove it.
X To activate: press theÁbutton.
The indicator lamp in the Ábutton lights
up.
X To deactivate: press theÁbutton.
The indicator lamp in the Ábutton goes
out.
i Residual heat is deactivated automati-
cally:
R after approximately 30 minutes
R when the ignition is switched on
R if the battery voltage drops
R if the coolant temperature is too low Auxiliary heating
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
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
WARNING
When operating the auxiliary heating parts of
the vehicle can get very hot. Make sure that
the exhaust system does not under any cir-
cumstances come into contact with easily
ignitable material such as dry grass or fuels.
The material could otherwise ignite and set the vehicle alight. Choose your parking spot
accordingly.
Operating the auxiliary heating is thus pro-
hibited at filling stations or when your vehicle
is being refuelled. You must therefore switch
off the auxiliary heating at filling stations.
! 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 the auxiliary heating on regularly
once a month for approximately ten
minutes.
The auxiliary heating heats the air in the vehi-
cle interior without using the heat of the run-
ning engine. The auxiliary heating is operated
directly using the vehicle's fuel. For this rea-
son, 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 switch 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 switching on X
Turn the key to position 2(Ypage 143) in
the ignition lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when climate control is set to
manual. Optimum comfort can be attained
when the system is set to automatic 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. 134

Problem Possible causes/consequences and
M Solutions
The coolant tempera-
ture display is showing
more than 120 †. A
display message may
also appearint
he mul-
tifunction display 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 293). 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
If the coolant temperature is below 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrain and stop-start traffic. Automatic transmission
Important safety notes
G
WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor
R, the vehicle could pull away suddenly. There
is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do
not simultaneously accelerate.
i Bear in mind that the power transmission
between the engine and the transmission
is interrupted when the engine is switched
off. Therefore, to prevent the vehicle from
rolling away, shift the automatic transmis-
sion to position Pand apply the parking
brake when the engine is switched off and
the vehicle is stationary. Selector lever
Overview of transmission positions !
If the engine speed is too high or if the
vehicle is rolling, do not shift the transmis- sion directly from
Dto R, from Rto Dor
directly to P.
Do not open the driver's door while the
vehicle is in motion. At low speeds in trans-
mission position Dor R, park position Pis
otherwise engaged automatically.
The transmission could be damaged. Selector lever
