Brake fluid
GWARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, storage
and disposal of service products on the labels
of the respective original containers. Always
store service products sealed in their original
containers. Always keep service products out
of the reach of children.
Brake fluid is hazardous to health. Also observe
the safety notes in the "Service products and
capacities" section (
Ypage 277).
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
!Brake fluid corrodes paint, plastic and rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
Have the brake fluid renewed every 2 year sat a
qualified specialist workshop. Observe the infor- mation on brake fluid in the "Technical data"
section (
Ypage 283).
Check the brake fluid level regularly, e.g. weekly
or when refueling.

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 26).
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 28).

Battery
Important safety notes
Work on the battery, e.g. removing or installing,
requires specialist knowledge and the use of
special tools. Therefore, always have work on
the battery carried out at a qualified specialist
workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g. the lighting sys-
tem, ABS (anti-lock braking system) or ESP
®
(Electronic Stability Program). The operating
safety of your vehicle may be restricted. You
could lose control of the vehicle, for example:
Rbraking
Rin the event of abrupt steering maneuver
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci- dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car-
ried out at a qualified specialist workshop.
Further information can be found under "ABS"
(
Ypage 53) and under "ESP®" (Ypage 54).
GWARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The flammable gas mix is produced when the
battery is charged or when the vehicle is jump-
started.
Always make sure that neither you nor the bat-
tery are electrostatically charged. Electrostatic
charging results, for example, from:
Rwearing synthetic clothing
Rfriction between clothing and the seat
Rdragging or pushing the battery across carpet flooring or any other synthetic materials
Rrubbing the battery with cloths or towels.
Comply with the following safety precautions
and take protective measures when handling
batteries.
Risk of explosion. Explosive oxyhy-
drogen is produced when batteries
are being charged. Only charge bat-
teries in well-ventilated areas.
Fire, open flames and smoking are
therefore prohibited when working
on the battery. Avoid creating
sparks.
Battery acid is caustic. Avoid con-
tact with the skin, eyes or clothing.
Wear acid-proof protective gloves. If
skin or clothes are splashed with
acid, neutralize the splashes imme-
diately with soapy water or an acid
neutralizer, and then clean the affec-
ted areas with water. Consult a doc- tor if necessary.
Wear eye protection. When mixing
water and acid, the liquid can splash
into your eyes. Rinse acid splashes
to the eyes immediately with clean
water and contact a doctor immedi-
ately.
Keep children at a safe distance.
Children are not able to assess the

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 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 your vehicle parked your vehicle
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 229).
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 232).
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.
