Exhaust gas aftertreatment
The exhaust gas aftertreatmen trequires a
reducing agent known as Diesel Exhaust Fluid
(DEF) in order to function correctly. Filling up
the DEF tank is usually part of the service
scope. DEFc onsumption depends on
operational and driving conditions and it is
not necessary to wait until the next scheduled
service to replenish the fluid. Fluid should be
added regularly to the DEFs upply reservoir
during vehicle operation or, at the latest, after
receiving the first warning message via the
on-board computer.
To conform to emission regulations, you must
operate the vehicle with DE Fand refill the
supply regularly .The engine management
recognizes attempts to operate the vehicle
without DEF, with thinned DEF or with
another reducing agent. After previous
warning messages, the engine management
then prevents a further engine start.
If the DEF level drops below 1.5 US gal
(5.5 l), the first warning message is issued
and a warning tone sounds. After the
message appears for the first time, and under
normal driving conditions, the remaining DEF
supply will last for approximately 1,000 mi
(1,600 km).
After that, the 0.8 US gal (3.0 l)reserve mark
is reached. Once the reserve range has been
reached, you will receive the next warning
message and you will hearas eries of warning
tones. After the first message, the DEF
reserve will last for approximately 1,200 mi
(1,900 km). However, you will only be able to
start the engine another 16 times.
You should immediately add 2.0 US gal
(7.6 l) of DEF (Y page 144) or have the DEF
supply reservoir filled at a qualified specialist
workshop.
When the number of remaining engine starts
is 0 , the engine management prevents the
engine being started.
If the 0018 checkengine indicator lamp lights
up, the exhaust gas aftertreatment is faulty or
an emission-related malfunctio nhas occurred (Y
page 204). You will then only be
able to drive a maximum 50 mi (80 km) before
the engine managemen trestricts the number
of starts remaining.
If the exhaust gas aftertreatment is faulty,
have it checked and repaired at a qualified
specialist workshop.
Further information on DEF can be found in
the "Refueling" ( Ypage 143) and "Service
products and capacities" (Y page 320)

General notes !
For safety reasons, have add-on
equipment manufactured and installed
according to the Sprinter body/equipment
mounting directives in force. These body/
equipment mounting directives ensure that
the chassis and the body form one unit and
that maximum operating and road safety is
achieved.
We recommend for safety reasons that:
R you carry out no other modifications to
the vehicle.
R you obtain the agreement of the
distributor named on the inside of the
front cover for any deviations from the
approved body/equipment mounting
directives.
Approval from certified inspection
agencies or official approvals cannot rule
out risks to your safety.
We recommend that you use genuine
Mercedes-Benzp arts as well as conversion
parts and accessories that have been
specifically approved by Mercedes-Ben zfor
the type of vehicle.
These parts have been specially tested to
establish their safety, reliability and
suitability. Introduction
