Maintenance
General notes
HEnvironmental note
Observe measures to protect the environ-
ment when working on the vehicle. You must
observe the legal requirements when dispos-
ing of service products, e.g. engine oil. This
also includes all components, e.g. filters,
which have come into contact with service
products. Any qualified specialist workshop
can provide information about this.
Dispose of empty containers, cleaning cloths
and care products in an environmentally
responsible manner. Comply with the instruc-
tions for use of the care products.
226Maintenance
Maintenance and care

Do not run the engine for longer than neces-
sary when the vehicle is stationary.
Before having maintenance and repairs per-
formed, it is essential to read the materials rela-
ted to the maintenance and repairs:
Rthe applicable sections of the technical doc-
umentation, e.g. the Operator's Manual and
workshop information.
Rregulations such as industrial safety regula-
tions and accident prevention regulations.
While working under the vehicle, you must
secure the vehicle on jack stands with sufficient load capacity.
Never use the jack as a substitute. The vehicle's
jack is intended only to raise the vehicle for a
short time when changing a wheel. It is not
suited for performing maintenance work under
the vehicle.
Please also refer to the notes about qualified
specialist workshops (
Ypage 27).
The scope and regularity of the inspection and
maintenance work primarily depend on the
often diverse operating conditions. Specialist
knowledge beyond the scope of this Operator's
Manual is required when carrying out testing
and maintenance work. This work should only be
carried out by trained staff.
The vehicle Maintenance Booklet describes the scope and fre que
ncy of maintenance work and
contains additional notes on the New Vehicle
Limited Warranty and on service products.
Maintenance services must be carried out in
accordance with the provisions and recommen-
dations in the Maintenance Booklet. Not doing
so could void the warranty claim and lead to
refusal of goodwill gestures after the manufac-
turer has submitted a damage report.
iObserve the notes on genuine Sprinter parts
(Ypage 29).
Service interval display
General notes
A service that is due is displayed in the service
interval display about one month in advance. A
message is then displayed while the vehicle is in
motion or when the ignition is switched on.
iThe service interval display does not provide
information about the engine oil level. The service interval display should therefore not
be confused with the
5engine oil level
display.
The service due date is displayed in days or
miles (kilometers), depending on the total dis-
tance driven.
The symbols or letters on the service display
show the type of service that is due.
