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-

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

Sliding/tilting sunroof*
G
Risk of injury
Children could injure themselves if they
operate the sliding/tilting sunroof.
Never leave children unsupervised in the
vehicle. Always take the key with you when
leaving the vehicle, even if you are only
leaving 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 there is a risk of
entrapment, release the switch and push it
briefly in any direction to stop the sliding/
tilting sunroof. G
Risk of injury
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 over-
turning. 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" and "Conve-
nience closing" features respectively. Controls

Risk of accident
On no account should you attempt to draw
the vehicle/trailer combination out by
increasing speed. Trailer po
wer supply
The trailer socket of your vehicle is equipped
at the factory with a permanent power supply.
The permanent power supply is supplied via
trailer socket pin 9.
! You can connect accessories with a max-
imum power consumption of 180 W to the
permanent power supply.
You must not charge a trailer battery using
the power supply.
You can obtain further information about
installing the trailer electrics from a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. Trailer with 7-pin connector
If your trailer has a 7-pin connector, you can
connect it to the 13-pin socket on the ball
coupling using an adapter or, if necessary, an
adapter cable. Both of these can be obtained
at a qualified specialist workshop, e.g. at a
Mercedes-Benz Service Centre.
Fitting the adapter 1
Connector with lug

nector clockwise to the stop. X
Make the cover engage.
X If you are using an adapter cable, secure
the cable to the trailer with cable ties.
! Make sure that there is sufficient cable
play so that the cable cannot become
detached when cornering.

Service
181Service
ASSYST service interval display
The ASSYST service display informs you when
the next service is due. Whenever a service is
due, this is shown in the multi-function dis-
play:
Service A in ..days
Service A in .. km
Service A due now The symbol and the letter indicate which type
of service is due:
9
Minor service A
½ Major service B
The ASSYST service display does not record
any periods of time during which the battery is disconnected. In order to maintain the
time-dependent service schedule, you should
call up the service due date and make a note
of it before disconnecting the battery. The
alternative is to subtract the battery discon-
nection periods from the service date shown
on the display.
Fading out the service message
The service message disappears automati-
cally after a few seconds. You can also fade
out the service message yourself.
1
Reset button
X Press reset button 1. Missing the service due date One of the following messages appears in the
multi-function display:
Service A overdue by .. days
Service A overdue by .. km
You will also hear a warning tone.
A qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre, resets the
ASSYST service display after the service work
has been carried out.
i If you fail to have the service performed
by the specified date, you may be violating
applicable laws. Your warranty may be inva-
lidated and goodwill settlements may be
refused.
Calling up the service due date Use the buttons on the multi-function steer-
ing wheel. Operation

Care
183H
Environmental note
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally responsible manner.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces, otherwise you could
damage the paintwork. Vehicle care
! Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature.
Automatic car wash You can wash the vehicle in an automatic car
wash from the beginning. !
Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use automatic car washes without
brushes.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise a risk of dam-
age to the exterior mirrors.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is fully turned off and that the wind-
screen wiper switch is set to 0. The rain
sensor may otherwise be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
After using an automatic car wash, wipe any
wax and drying agents off the windscreen and
the wiper blades. This will prevent smears and
reduce wiping noises caused by residue on
the windscreen. High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with cir-
cular-jet nozzles (dirt grinders) to clean
your vehicle or ― especially ― the tyres.
Otherwise, you could damage the tyres and
cause an accident.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door joint
R electrical components
R battery
R connectors
R lights
R seals
Damaged seals or electrical components
can lead to failures or leaks. Operation
