Disconnecting/connecting the
starter battery
Important safety notes
GWARNING
During the charging process, a battery produ-
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
electronic components such as the alterna-
tor.
Always disconnect the starter battery in the
battery case in the left-hand side footwell
first.
!Always disconnect the battery in the order
described below. Never swap the terminal
clamps. You may otherwise damage the vehi- cle electronics.
If the vehicle is expected to be out of use for over
3 weeks, disconnect the batteries. This will pre-
vent battery discharge caused by off-load cur-
rent consumption.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 27).
Vehicle electronics
Tampering with the engine electron-
ics
GWARNING
Always have work on the engine electronics
and related components carried out at a quali-
fied specialist workshop. Otherwise, the vehi-
cle's operating safety could be affected.
!Only have engine electronics and the corre-
sponding parts, such as control units, sensors or connector leads, serviced in a qualified
specialist workshop. Otherwise, the vehicle
parts may wear more quickly. This can lead to
loss of the New Vehicle Limited Warranty.
Installing electrical or electronic
equipment
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
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. Electrical and electronic devices may have a
detrimental effect on both the comfort and the
operating safety of the vehicle. If equipment of
this kind is installed, its electromagnetic com-
patibility must be checked and verified.
If these devices are linked to functions associ-
ated with resistance to interference, they must
have type approval. This applies to the device or
its interfaces to the vehicle electronics, e.g.
charging brackets.
A telephone or two-way radio to be installed in
the vehicle must be approved. Further informa-
tion can be obtained from any Sprinter Dealer.
For operation of mobile phones and two-way
radios, Mercedes-Benz recommends connec-
tion to an approved exterior antenna. This is the
only way to ensure optimum reception quality
inside the vehicle and to minimize mutual inter-
ference between the vehicle electronics, mobile
phones and two-way radios.
The transmission output of the mobile phone or
two-way radio may not exceed the following
maximum transmission output (PEAK):
Frequency rangeMaximum trans-
mission output
