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.

dangers posed by batteries and
acid.
When handling batteries, observe
the safety precautions and special
protective measures contained in
this Operator's Manual.
HEnvironmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separatelyand recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
Observe the following notes:
RRecharge the battery more frequently, if you:
-predominantly drive short distances
-predominantly drive at low outside temper-
atures
-park the vehicle for longer than
three weeks.
In order for the batteries to achieve their max- imum possible service life, they must always
be sufficiently charged.
RWhen you park the vehicle, remove the key if
you do not require any electrical consumers.
The vehicle will then use very little energy,
thus conserving battery power.
RWhen replacing a battery, only use batteries
that are recommended for use in Sprinter
vehicles.
RHave the battery removed at a qualified spe-
cialist workshop.
RIf you leave the vehicle parked for longer than
three weeks:
-consult a qualified specialist workshop or
-switch off the power supply using the bat-
tery main switch (Ypage 118) or
-disconnect the batteries (Ypage 230). Otherwise, you need to check the battery's
condition of charge every three weeks, since
standby power consumption can drain the
battery. If the battery voltage is lower than
12.2 V, the battery must be charged. Other-
wise, the battery may be damaged by exhaus-
tive discharging.
Be sure to observe the notes on charging the
batteries (
Ypage 233).
Installation locations
Your vehicle may be equipped with three bat-
teries, depending on the equipment version:
RStarter battery in the battery case in the left
footwell
RAdditional battery in the engine compartment
RAuxiliary battery under the left-hand front
seat
Have the auxiliary battery removed at a qualified
specialist workshop.

Important safety notes
GWARNING
Functions relevant to safety are restricted or
no longer available if:
Rthe engine is not running.
Rthe brake system or the power steering is
malfunctioning.
Rthere is a malfunction in the voltage supply or the vehicle's electrical system.
If your vehicle is being towed, much more
force may be necessary to steer or brake.
There is a risk of an accident.
In such cases, use a tow bar. Before towing,
make sure that the steering moves freely.
GWARNING
You can no longer steer the vehicle if the
steering wheel lock has been engaged. There
is a risk of an accident.
Always switch off the ignition when towing the
vehicle with a tow cable or a tow bar.
GWARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible
gross weight of your vehicle, the:
Rthe towing eye could detach itself
Rthe vehicle/trailer combination could roll-
over.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
Information on the gross vehicle weight can be
found on the vehicle identification plate
(
Ypage 276).
!Only secure the tow rope or tow bar at the
towing eyes. Otherwise, the vehicle could be
damaged.
!Observe the following points when towing
with a tow rope:
RSecure the tow rope on the same side on
both vehicles.
REnsure that the tow cable is not longer than
legally permitted. Mark the tow cable in the
middle, e.g. with a white cloth (30 x 30 cm).
This will make other road users aware that
the vehicle is being towed.
ROnly secure the tow cable to the towing
eye.
RObserve the brake lamps of the towing
vehicle while driving. Always maintain a dis-
tance so that the tow rope does not sag.
RDo not use steel cables or chains to tow
your vehicle. You could otherwise damage
the vehicle.
!Do not use the towing eye for recovery, this
could damage the vehicle. If in doubt, recover
the vehicle with a crane.
!When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
When towing away, you must observe the legal
requirements for the country in which you are
currently driving.
It is preferable to have the vehicle transported
on a transporter or trailer instead of towing it.
