Switching air-recirculation mode
on/off
Important safety notes You can deactivate the intake of fresh air if
unpleasant odors enter the vehicle from out-
side. The air inside the vehicle is then circula-
ted.
When you switch on air-recirculation mode,
the side windows and windows could fog up
more quickly, in particular at low outside tem-
peratures. Only switch on air-recirculation
mode for a short time.

X Press the h button.
If the indicator lamp in the h button
lights up, air-recirculation mode is activated.
Air-recirculation mode switches on automati-
cally: R at high outside temperatures

WARNING
During convenience opening, body parts
could be drawn in or become trapped
between the side window and the door
frame. There is a risk of injury. Monitor the entire opening procedure when
using convenience opening. When opening,
make sure that nobody touches the side
window. Release the % switch immedi-
ately if somebody becomes trapped, to
interrupt the opening procedure.
X Pre-entry climate control and conveni-
ence opening with the key:
press and hold
the % button on the key.
The side windows open automatically and
the blower of the climate control system is
activated.
X Release the % button.
i At high interior temperatures, the blower is
also switched on when a door is opened.
This means that slightly cooled air enters
the vehicle interior after the engine is star-
ted, to cool the vehicle more rapidly. Switching the residual heat function
on/off
General notes Only vehicles with dual-zone automatic climate
control have the residual heat function.
Once the engine is switched off, it is possible
to make use of the residual heat of the engine
to continue heating or ventilating the front
compartment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.
Switching the function on/off X
Turn the key to position 0 in the ignition
lock or remove it.
X Press the Ì button.
If the residual heat function is activated, the
indicator lamp in the Ì button comes on.
The blower will run at a low speed regard-
less of the airflow setting.
If you activate the residual heat function at
high temperatures, only the auxiliary ventila-
tion will be activated. The blower then runs
at medium speed. Operating the climate control system

Important safety notes
G
WARNING
Fuel is highly flammable. Improper handling
of fuel creates a risk of fire and explosion.
Avoid fire, open flames, smoking and creat-
ing sparks under all circumstances. Switch
off the engine and, if applicable, the auxiliary
heating before refueling. G
WARNING
Fuels are toxic and harmful to health. There
is a risk of injury.
You must avoid fuels coming into contact
with skin, eyes and clothes or being swal-
lowed.
Do not inhale the fuel vapors. Keep children
away from fuels.
Keep doors and windows closed during the
refueling process. 136

Always make sure that neither you nor the bat-
tery are electro statically charged.
An electrostatic charge can build up in the fol-
lowing situations:
R wearing synthetic clothing
R friction between clothing and the seat
R dragging or pushing the battery across car-
pet flooring or any other synthetic materials
R by rubbing the battery with a cloth or towels
Comply with the following safety precautions
and take protective measures when handling
batteries. Risk of explosion. Explosive oxyhy-
drogen is produced when batteries
are being charged. Only charge
batteries in well-ventilated areas.
Fire, open flames and smoking are
therefore prohibited when working
on the battery. Avoid creating
sparks.
Battery acid is caustic. Avoid con-
tact with the skin, eyes or clothing.
Wear acid-proof protective gloves.
If skin or clothes are splashed with
acid, neutralize the splashes imme-
diately with soapy water or an acid
neutralizer, and then clean the
affected areas with water. Consult
a doctor if necessary.
Wear eye protection. When mixing
water and acid, the liquid can
splash into your eyes. Rinse acid
splashes to the eyes immediately
with clean water and contact a
doctor immediately.
Keep children at a safe distance.
Children are not able to assess the
dangers posed by batteries and
acid.
When handling batteries, observe
the safety precautions and special
protective measures contained in
this Operator's Manual.
H
Environmental note Batteries contain pollutants.
It is illegal to dispose of
them with the household
rubbish. They must be col-
lected separately and dis-
posed of in an environmen- tally responsible recycling
system. Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop or to a col-
lection point for used bat-
teries.
Observe the following notes: R have the batteries recharged more fre-
quently in the following situations:
- if you predominantly drive short distan-
ces.
- if you predominantly drive at low outside
temperatures.
- if you leave the vehicle parked for a
lengthy period.
In order for the batteries to achieve their
maximum possible service life, they must
always be sufficiently charged.
R Consult an authorized Mercedes-Benz Com-
mercial Van Center if you wish to leave your
vehicle parked for a long period of time.
R When you park the vehicle, remove the key
if you do not require any electrical consum-
ers. The vehicle will then use very little
energy, thus conserving battery power.
R If your vehicle requires jump-starting, or if
you wish to provide jump-starting assistance
to another vehicle, only use the jump-start-
ing connection point in the engine compart-
ment
(Y page 272).
R Have the battery removed at a qualified spe-
cialist workshop. Installation locations
Your vehicle may be equipped with the follow-
ing three batteries, depending on the equip-
ment level:
R Starter battery in the seat base of the right-
hand front seat
R Auxiliary battery in the seat base of the
right-hand front seat
R Additional battery in the seat base of the
left-hand front seat Battery

Disconnecting and removing
G
WARNING
During the charging process, a battery pro-
duces hydrogen gas. If a short circuit occurs
or sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
R Never place metal objects or tools on a
battery.
R It is important that you observe the
described order of the battery terminals
when connecting and disconnecting a bat-
tery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
R Never connect or disconnect the battery
terminals while the engine is running. G
WARNING
Battery acid is caustic. There is a risk of
injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
! You should have all work involving the bat-
tery carried out at a qualified specialist
workshop.
If, in exceptional circumstances, you need
to disconnect the battery yourself, please
make sure that:
R Secure the vehicle to prevent it from roll-
ing away.
R You have switched off the engine and
removed the key. Make sure the ignition
is switched off. Check to see that there
are no indicator lamps lighting in the instrument cluster. Electronic compo-
nents such as the alternator may other-
wise be damaged.
R After the battery has been disconnected,
the parking brake is automatically
engaged. You can then no longer move
the vehicle.
R For vehicles with automatic transmission,
the transmission is locked in position P
after disconnecting the battery. You can
then no longer move the vehicle.
R You have first removed the negative ter-
minal and then the positive terminal.
Never mix up the terminal clamp discon-
nection/connection order and never mix
up the terminal clamps. The vehicle's
electronics may otherwise be damaged.
The battery and the cover of the positive ter-
minal clamp must be installed securely dur-
ing operation. Seat base (example: right-hand front seat)
The following description on disconnecting
and removing the battery is based upon the
example of the starter battery in the seat base
of the driver's seat. The additional battery is
disconnected and removed in the same way as
the starter battery. The auxiliary battery is
located in the seat base of the left-hand front
seat.
X Switch off all electrical consumers.
X Switch off the engine and remove the key
from the ignition lock.
X Open the front door on the right-hand side.
i To disconnect or remove the additional
battery, open the left-hand front door. The
auxiliary battery is located in the seat base
of the left-hand front seat. 260
