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.

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

GWARNING
During the charging process ,abattery produ-
ces hydrogen gas. If ashort circuit occurs or
sparks are created, the hydrogen gasc an
ignite. There is ariskofane xplosion.
RMake sure that the positive terminal of a
connected battery doe snot come into con-
tact with vehicle parts.
RNeve rplace metalo bjects or toolsonab at-
tery.
RIt is important that yo uobserve the descri-
bed order of the battery terminal swhen

RWhe njump-starting, make sure that the
battery poles with identica lpolarity are
connected.
RIt is particularly important to observe the
described order whe nconnecting and dis-
connecting the jumper cables.
RNeve rconnect or disconnect the battery

RSecure the vehicle to prevent it from rolling
away.
RYou have switched off the engine and
removed the key.M akes uret he ignition is

sur eelectronically" (
Ypage 276).
Important safety notes
GWARNING
Each tire, including the spare (ifp rovided),
should be checked at least once amonth
whe ncold and inflated to the pressure rec-
ommended by the vehicle manufacturer on
the Tir eand Loading Information placard on
the driver's doo rB-pilla rort he tire pressure
label on the inside of the fue lfiller flap. If your
vehicle has tires of adifferent size than the
size indicated on the Tir eand Loading Infor-
mation placard or the tire pressure label ,you
should determine the proper tire pressure for
those tires.
As an added safety feature ,you rv ehicle has
bee nequipped with atire pressure monitoring
system (TPMS) that illuminates alow tire pres-
sur etelltal ewheno ne or more of your tires
are significantly underinflated. Accordingly,
whe nthe low tire pressure telltal eillumi nates,
yo us hould stop and check your tires as soon
as possible, and inflate them to the proper
pressure. Driving on asignificantly underin-
flated tire causes the tire to overheata nd can
lea dtot ire failure. Underinflation also
reduce sfue lefficiency and tire treadl ife, and
may affect the vehicle' shandling and stop-
ping ability.
Please note that the TPMSisn otas ubstitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMSl ow tire pressure telltale.
USA only:
You rvehicle has also bee
nequipped with a
TPM

Sm alfunction indicator to indicate if the
system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. Whe nthe system
detects amalfunction, the warning lamp will
flash for approximately aminute and then
remain continuously illuminated. This
sequence will be repeated ever ytime the vehi-
cle is starte daslong as the malfunction
exists.
Whe nthe malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMSm alfunc-
tions may occur for avariety of reasons,
including the mounting of incompatible
replacement or alternate tires or wheels on
the vehicle that prevent the TPMSf rom func-
tioning properly. Alway scheck the TPMSm al-
function telltal eafterreplacing one or more
tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels
allow the TPMStoc ontinuetofunction prop-
erly.
It is the driver's responsibility to set the tire
pressure to the recommende dcold tire pressure
suitabl efor the operating conditions
(
Ypage 270).
Note that the correct tire pressure for the cur-
rent operating conditions mus tfirs tb ep ro-
gramed into the tire pressure monitor. If there is
as ubstantial los sofpressure, the warning
threshol dfor the warning messag eisaligne dto
the reference value sprograme din. Restart the
tire pressure monito rafte radjusting the cold
tire pressure (
Ypage 277). The current pres-
sures are saved as new reference values. This
will ensure that awarning messag ewillo nly
appea rifthe tire pressure drop ssignificantly.
The tire pressure monito rdoesn ot warn yo uifa

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
pressure values.
