than approved anticorrosion/antifreeze
products for your vehicle are being used.
You can find coolant instructions under the
"Coolant" section of the vehicle Operator's
Manual. Contact an authorized Sprinter
dealer for a list of anticorrosion/antifreeze

The
maintenance computer recommends the
inspection of certain wear parts, however, it
cannot judge the condition of these wear
parts. Only a qualified aftersales technician
can determine if a wear part should be
replaced. Approved engine oils and filters
General information about engine oil Engine oils and oil filters are especially tested
for their suitability in our engines and
durability

for our service intervals. Therefore,
only use approved engine oils and oil filters
required for vehicles with a maintenance
computer. Conventional petroleum-based
oils must not be used for vehicles equipped
with the ASSYST maintenance computer.
The following cases are not covered by the
limited warranty for new vehicles:
R using engine oils and oil filters of
specification other than those expressly
required by the maintenance computer.
R changing the engine oil and oil filter at
longer change intervals than those
specified by the maintenance computer.
R using any oil additives.
We recommend MOBIL OIL. MB sheet numbers Use the following table to determine the MB
sheet numbers. Refer to the Operator's

vehicle. The model and engine type can be
found in the "Service products and
capacities" section of the "Technical data"
chapter under "Engine oil".

In addition to the maintenance service, you
should also perform regular checks on the
following (e.g. weekly, when refueling or
before any long journey):
