!Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
Example: cap and coolant expansion tank
Checkingt he coolant level
XStop your vehicle as far awayf rom traffic as
possible on level ground.
XSwitch off the engine.
XSecure the vehicle to prevent it from rolling
away.
XOpen the hood (Ypage 241).
XSlowly turn cap :half aturn counter-clock-
wise to allow excess pressure to escape.
XTurn cap :further and remove it from cool-
ant expansion tank ;.
XCheck the coolant level.
If the coolant is up to marker bar =in the
filler neck when cold, there is asufficient
amount of coolant in coolant expansion
tank ;.
If the coolant is approximately 0.59 in
(1.5 cm) above marker bar =in the filler neck
when warm, there is asufficient amount of
coolant in coolant expansion tank ;.
Adding coolant
XIf the coolant drops under marker bar =in
the filler neck, add coolant.
Observe the information on the correct cool-
ant mixture ratio and the required water qual-
ity under "Service products and capacities"
(
Ypage 300). To prevent damage to the
engine cooling system, use only approved
corrosion inhibitor/antifreeze that complies
with the Mercedes-Benz Specifications for
Service Products.
XReplace cap :and turn it clockwise to
tighten.
XStart the engine.
XSet the temperature in the vehicle interior to
the maximum output on the air-conditioning
system control panel.
XAfter approximately 5minutes ,switch off the
engine and allow it to cool down.
XCheck the coolant level againa nd add coolant
if necessary.
XClose the hood.

service interval displayshould therefore not
be confused with the engine oil level display.
For example, the displays hows one of the fol-
lowing service messages for afew seconds:
RNext Service Ain..Days
RServiceADueorService ADue
RServ. AExceed. by .. Days
Then either the remaining time or distance until
the next service due date is displayed. If the
service due date has been exceeded, the
elapsedt ime or distance traveled after the over-
due service date is shown. The letter in the dis-
play message indicates which service is due. A
stands foraminor service and Bforam ajor ser-
vice.
Aq ualified specialist workshop, e.g. an author-
ized Mercedes-Benz Commercial Van Center,
will reset the service interval displaya fter the
service work has been carried out. You can also
obtain further information on maintenance
work, for example.
The prescribed service interval is based on nor- mal vehicle use. Service work will need to be
performed more frequently than prescribed if
the vehicle is operated under more arduousc on-
ditions or with higher loads. Such arduousc on-
ditions include:
Rregularc ity driving with frequent intermediate
stops
Rdriving predominantly short distances
Rfrequent operation in mountainous terrain or
on poor road surfaces
Rleaving the engine idling for long periods on a frequent basis
In these or similar operating conditions, have
the air filter, engine oil and oil filter, for example,
replaced more frequently. Under more arduous
operating conditions, the tires must be checked more often. Further information can be obtained
at aq ualified specialist workshop, e.g. an
authorized Mercedes-Benz Commercial Van
Center.

Important safety notes
Work on the battery, e.g. removing or installing,
requires specialist knowledge and the use of
special tools. Therefore, always have work on
the battery carried out at aqualified specialist
workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to ashort circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the
ESP
®(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is arisk of an accident.
In the event of ashort circuit or asimilari nci-
dent, contact aqualified specialist workshop

!Vehicles withagasolinee ngine:avoid
repeated and lengthy starting attempts. Oth-
erwise, the catalytic converter could be dam-
aged by non-combusted fuel.
If the indicator and warning lamps in the instru-
ment cluster do not light up at low tempera-
tures, the discharged battery may have frozen.
In this case you may neither charge the battery
nor jump-start the vehicle. The service life of a
thawed battery may be shorter. Start-up behav-
ior may deteriorate, in particular at low temper-
atures. Have the thawed battery checked at a
qualified specialist workshop.
Do not use arapid charging device to start the
vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another
vehicle or from adonor battery using jumper
cables. For this purpose, the vehicle has ajump-
starting connection point in the engine com-
partment.
When jump-starting, observe the following
points:
RThe battery is not accessible in all vehicles. If
the other vehicle's battery is not accessible,
jump-start the vehicle using adonor battery
or ajump-startingd evice.
RYou may only jump-start the vehicle when the
engine and exhaust system are cold.
RDo not start the engine if the battery is frozen.
Let the battery thaw first.
RJump-starting may only be performed from
batteries with anominal voltage of 12 V.
ROnly use jumper cables that have asufficient
cross-section and insulated terminal clamps.
RIf the battery is fully discharged, attach the
battery of another vehicle for afew minutes
before attempting to start. This charges the
empty battery alittle.
RMake sure that the two vehicles do not touch.
Make sure that:
Rthe jumper cables are not damaged.
Rbare parts of the terminal clamps do not come
into contact with other metal parts while the
jumper cables are connected to the battery.
Rthe jumper cables cannot come into contact
with parts such as the V-belt pulley or the fan.
These parts move when the engine is started
and while it is running.
Jumper cables and further information regarding
jump starting can be obtained at any qualified
specialist workshop.
Before connecting the jumper cables
XApply the parking brake.
XShift the transmission to position P.
XSwitch off all electrical consumers, e.g. audio
equipment, blower.
XTurn key to position 0in the ignition lock and
remove it.
XOpen the hood (Ypage 241).
Connecting the jumper cable
XPush contact protection cover :of the jump-
starting connection point backwards against
the spring force as far as it will go.
The jump-startingc onnection point is visible.
Terminal connecting plan
XRemove the cover from positive terminal =
of the donor vehicle's battery.
XConnect the positive terminal clamp of the
