Activating/deactivating cooling with air dehumidification
General notes If you deactivate the "Cooling with air-dehumidification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up
more quickly. Therefore, only deactivate the "Cooling with air-dehumidification" function
briefly.
The "Cooling with air dehumidification" function is only available when the engine is running.
The air inside the vehicle is cooled and dehumidified according to the temperature selected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunction.
Switching cooling with air dehumidification on/off !
If the cooling with air dehumidification does not switch on, it is possible that the climate
control system has lost coolant.
Have the cooling with air dehumidification checked at a qualified specialist workshop. Canada only

Problems with the rear window
defroster
If the indicator lamp in the
ªrear window
defroster button flashes, the on-board volt-
age is too low. The rear window defroster has
deactivated prematurely or cannot be activa-
ted.
X Switch off any consumers that are not
required, e.g. reading lamps or interior
lighting.
When the battery is sufficiently charged,
the rear window defroster is activated
again automatically. Activating/deactivating air-recircula-
tion mode
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.
X Turn the SmartKey to position 2in the igni-
tion lock (Y page 133).
X To activate: press thedbutton.
The indicator lamp in the dbutton lights
up.
i Air-recirculation mode is automatically
activated at high levels of pollution or at
high outside temperatures. When air-recir-
culation mode is activated automatically,
the indicator lamp in the dbutton is not
lit.
Outside air is added after approximately
30 minutes. X
To deactivate: press thedbutton.
The indicator lamp in the dbutton goes
out.
i Air-recirculation mode switches off auto-
matically:
R after approximately five minutes at out-
side temperatures below approximately
41 ‡
R after approximately five minutes if cool-
ing with air dehumidification is deactiva- ted
R after approximately 30 minutes at out-
side temperatures above approximately
41 ‡ (5 †) Activating/deactivating the residual
heat function
The "residual heat" function is only available
in Canada.
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 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 SmartKey to position
0(Y page 133) in the ignition lock or
remove it.
X To activate: press theÁbutton.

Problem
Possible causes/consequences and
M
MSolutions The coolant tempera-
ture gauge shows a
value above 248 ‡
(120 †). A display mes-
sage may also appear in the multifunction dis-
play 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 278). Observe the warning
notes as you do so and add 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 below 248 ‡ (120 †), drive 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-and-go 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. G
WARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
i Bear in mind that the power transmission
between the engine and the transmission is
interrupted when the engine is switched
off. For this reason, shift the automatic
transmission to Pwhen the engine is
switched off and the vehicle is at a stand- still. Apply the parking brake to prevent the
vehicle from rolling away. 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. Automatic transmission
