Emission system maintenance
Emission control system caution -
diesel engines
Your Sprinter is equipped with emission
control
devices to comply with current diesel
exhaust emission regulations in countries
where the vehicle is certified for sale.
Observe our recommended maintenance
instructions in order to ensure the proper
operating state of your vehicle.
Observe the following:
a) Diesel engines require diesel fuel with
extremely low sulfur content for road vehicles
(maximum 15 ppm sulfur), in compliance with
ASTM standard D975. Failure to use ultra low
sulfur highway diesel fuel (ULSD) can severely
damage the vehicle's exhaust gas
aftertreatment system.
b) We approve the use of B5 (standard ULSD
which may contain up to 5% bio-diesel) for all
BlueEFFICIENCY ®
diesel engines.
Diesel fuels which contain a higher proportion
of bio-diesel, e.g. B20, or pure bio-diesel fuel
can severely damage the engine and fuel
system and are not permitted.
Contact your service center for further
information. If the B5 biodiesel blend is not
sufficiently labeled to clearly indicate that it
meets the USLD standard, it should not be
used. The New Vehicle Limited Warranty for
new vehicles does not cover damage caused
by the use of fuels not meeting fuel standards
approved by the distributor named on the
inside of the front cover.
c) The prescribed engine maintenance
work must be carried out fully and at the
required intervals.
d) Exhaust gas aftertreatment system
operation must not be modified in any
way. Alterations are not permissible by law.
Alterations can also damage the catalytic
converter and result in increased fuel
consumption and impaired engine running
conditions. If the "CHECK ENGINE" indicator lamp lights
up

in the instrument cluster when the engine
is running, this indicates that there may have
been a malfunction in the engine control
system or in the exhaust gas aftertreatment
system.
We recommend that the malfunction is
checked as soon as possible. BlueEFFICIENCY
®
exhaust gas
aftertreatment using DEF
BlueEFFICIENCY ®
exhaust gas
aftertreatment requires a reducing agent
(DEF) in order to function properly.
Maintaining

the level and condition of the DEF
is part of the regular maintenance service
work.
DEF is a non-flammable, non-toxic, colorless
and odorless, water-soluble liquid.
! Only use DEF according to ISO 22241. Do
not add special additives to DEF or dilute it
with water. This can damage the
BlueEFFICIENCY ®
exhaust gas
aftertreatment. Description of emission system
maintenance jobs
The composition of exhaust emissions is
influenced not only by the exhaust gas
aftertreatment system, but also by various
engine parts and their settings.
Maintenance of the exhaust system must
therefore include these engine parts. Some
maintenance jobs are actually only tests.
They are important, however, because they
allow early detection of discrepancies which
can later lead to increased exhaust
emissions.

It is generally less costly to adjust
deviations of this sort immediately than to
wait until they incur high repair costs. The
maintenance intervals have been determined
so that the vehicle, under normal operating 8
