For example, the displays hows one of the fol-
lowing service messages for afew seconds:
RNext Service Ain..Days

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.

Battery
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

Maximum tire pressures
:Maximumpermitted tire pressure (example)
Never exceed the maximu mpermissible tire
inflation pressure. When adjusting the tire pres-
sure salway sobserve the recommendedt ire
pressure for you rvehicl e(
Ypage270).
iThe actua lvalues for tires are specific to
each vehiclea nd may deviate from the values
in the illustration.
Tire valve (snap-in valve)
Important safety notes
GWARNING
Tire valve that are not approved for you rvehi-
cle by the distributor named on the inside
cover pag emay result in aloss of tire pres-
sure .This may affect road safety .There is a
risk of an accident.
Only use tire valve that are approved for your
vehiclebyt he distributor named on the inside
cover page. Always make sure you have the
correct tire valve type for the tires on your
vehicle.
!Do not screw additiona lweights (check
valves, etc.) onto the tire valves. The elec-
tronic components coul dthus be damaged.
iFor safety reasons, Mercedes-Benz recom-
mends that you only use tire valve sthat have
been tested for use on you rvehicle.
Checking the tire pressure manually
In order to determine and adjust the tire pres-
sures, proceedasf ollows:
XRemove the valve cap of the tire you wis hto
check.
XPress the tire pressure gauge securely onto
the valve.
XRea dthe tire pressure and compare it with the
recommendedv alueont he loading informa-
tion table or the tire pressure table
(
Ypag e270).
XIf the tire pressure is too low ,increas eittothe
recommendedv alue.
XIf the tire pressure is too high ,release air by
pressing downt he metal pin in the valve .Use
the tip of apen, for example. Then, check the
tire pressure again using the tire pressure
gauge.
XScrew the valve cap onto the valve.
XRepeat the steps for the other tires.
Tire pressure monitor
General notes
In vehicles with atire pressure monitor system,
the vehicle's wheels have sensors installed
which monitor the tire pressure in all four tires.
The tire pressure monitor warns you if the pres- sure drops in one or more of the tires. The tire
pressure monitor only functions if the corre-
sponding sensors are installed on all wheels.
Tire pressure display (only on vehicles with steer-
ing whee lbuttons)

Restarting the tir epressure monitor
General notes
When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamp goes out. The monitor uses the
currently set tire pressures as the referenc eval-
ues for monitoring. In most cases, the tire pres-
sure monitor will automatically detec tthe new
referenc evalues after you have changed the tire
pressures. However,y ou can also define refer-
enc evalues manually as described here. The tire
pressure monitor then monitors the new tire
