Air conditioning
129Activating/deactivating air-recircula-
tion mode
You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated. G
Risk of accident
Only switch over to air-recirculation mode
briefly at low outside temperatures. Other-
wise, the windows could mist up, thus
impairing visibility and endangering your-
self and others. This may prevent you from
observing the traffic conditions, thereby
causing an accident.
X To activate: briefly press the ,button.
The indicator lamp in the ,button
comes on.
i Air-recirculation mode is activated auto-
matically at high outside temperatures.
When air-recirculation mode is activated
automatically, the indicator lamp in
the , button is not lit.
Outside air is added after about 30
minutes. X
To deactivate: press the,button.
The indicator lamp in the ,button goes
out.
i Air-recirculation mode switches off auto-
matically:
R after approximately five minutes at out-
side temperatures below approximately
5 †
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
5 † Switching the residual heat on/off
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 Make sure that the key is in position 1or
0 in the ignition lock or that it has been
removed.
X To switch on: press the9button.
The indicator lamp in the 9button lights
up.
X To deactivate: press the9button.
The indicator lamp in the 9button goes
out.
i 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
R when the coolant temperature is too low Cont

Cap
X Unscrew cap 1and remove it.
X Top up with the amount of oil required.
! Do not add too much oil. If too much oil
is added and the oil level is above the max-
imum mark on the dipstick, the engine or
catalytic converter could be damaged.
Have excess oil siphoned off.
X Screw cap 1onto the filler neck. H
Environmental note
When topping up the oil, take care not to
spill any. Oil must not be allowed to escape
into the soil or waterways. You would oth-
erwise be damaging the environment. Oil level in the automatic transmis-
sion
There is no need for you to check the oil level
in the automatic transmission. In the event of
oil loss or problems with gearshifts, have the
automatic transmission checked at a quali-
fied specialist workshop, e.g. at a Mercedes-
Benz Service Centre. Coolant
G
Risk of injury
The cooling system is pressurised. There-
fore, only unscrew the cap once the engine
has cooled down. This means the coolant
temperature gauge must display less than
70 °C. You could otherwise be scalded by
escaping hot coolant.
Coolant consists of water and antifreeze/cor-
rosion inhibitor. Only check the coolant level
when the vehicle is on a level surface and the
engine has cooled down. Checking the coolant level The expansion tank is located in the engine
compartment on the right-hand side of the
vehicle when viewed in the direction of travel.
1
Cap
X Slowly turn cap 1by half a turn in the
direction of the arrow to release excess
pressure.
X Unscrew cap 1completely and remove it.
X Turn cap 2further anti-clockwise and
remove it.
There is sufficient coolant in the expansion
tank if the coolant is level with the mark in
the expansion tank when the coolant is cold
or approximately 1.5 cm higher when hot. Operation

Top up the coolant if necessary.
X Replace cap 1and tighten all the way to
the stop.
You will find further information about coolant
in the "Technical data" section
(Y page 280). Windscreen washer system/head-
lamp cleaning system
The washer fluid reservoir is located in the
engine compartment on the right when
viewed in the direction of travel. The head-
lamp cleaning system is also supplied from
the washer fluid reservoir. 1
Cap
X Add windscreen washer concentrate to the
washer fluid all year round. G
Risk of fire
Windscreen washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windscreen washer
concentrate is being handled.
Use
R a windscreen washer fluid additive
such as MB Summerwash to prevent
smearing (for temperatures above freez-
ing).
R a windscreen washer fluid additive with
antifreeze properties such as MB Winter-
wash (if there is a risk of frost).
X Mix the windscreen washer fluid in a con-
tainer beforehand. Adapt the mixing ratio
to the outside temperatures.
! Only use windscreen washer fluid which
is suitable for plastic lamp lenses. Unsuit-
able windscreen washer fluid could dam-
age the plastic lamp lenses of the head-
lamps.
X To open: pull cap1upwards by the tab.
X To close: press cap 1onto the filler neck
until it clicks into place. Tyres and wheels
Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These tyres have been specially adap-
ted for use with the control systems, such
as ABS or ESP ®
, and are marked as follows:
R MO = Mercedes-Benz Original
If you use other tyres and wheels,
Mercedes-Benz cannot accept any respon-
sibility for damage that may result. Further
information about tyres, wheels and
approved combinations can be obtained
from any Mercedes-Benz Service Centre.
If you use tyres other than those tested and
recommended for Mercedes-Benz vehi-
cles, characteristics such as handling, vehi-
cle noise emissions and fuel consumption
may be adversely affected. In addition, the
wheels may come into contact with the
body or axle components when heavily loa-
ded or when driving with snow chains. This
could result in damage to the tyres or the
vehicle. Operation
