If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also lose
control of the vehicle. There is a risk of an
accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the country
in which you are currently driving when operat-
ing mobile communication equipment.
Please remember, a navigation system does not
supply information on the load-bearing capacity of bridges or the overhead clearance of under-
passes. The driver remains responsible for
safety at all times.
You and others can suffer health-related dam-
age through electromagnetic radiation. By using
an exterior antenna, a possible health risk
caused by electromagnetic fields, as discussed
in scientific circles, is taken into account. Only
have the exterior antenna installed by a qualified
specialist workshop.
You will find information on installing electrical
or electronic equipment in the “Vehicle elec-
tronics” section (

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.
Installing/removing the floor cover-
ing (starter battery)
GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on

ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
RMake sure that the positive terminal of a
connected battery does not come into con- tact with vehicle parts.
RNever place metal objects or tools on a bat-
tery.
RIt is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
Disconnecting the starter battery
!Switch off the engine and remove the key
from the ignition lock. Firstly remove the bat-
tery terminals. Otherwise, you could destroy
