WARNING Risk of explosion from hydro‐
gen gas igniting
A battery generates hydrogen gas during the
charging process. If there is a short circuit or
sparks start to form, there is a danger of the
hydrogen gas igniting.
#
Make sure that the positive terminal of
the connected battery does not come
into contact with vehicle parts.
#
Never place metal objects or tools on a
battery.
#
When connecting and disconnecting the
battery, you must observe the described
order for the battery clamps.
#
When giving starting assistance, always
make sure that you only connect battery
terminals with identical polarity.
#
During starting assistance, you must
observe the described order for con‐
necting and disconnecting the jumper
cables.
#
Do not connect or disconnect the bat‐
tery clamps while the engine is running.
&
WARNING Risk of explosion during
charging process and starting assistance
During the charging process and starting
assistance, the battery may release an explo‐
sive gas mixture.
#
Avoid fire, open flames, creating sparks
and smoking.
#
Make sure that there is sufficient venti‐
lation during the charging process and
during starting assistance.
#
Do not lean over a battery.

WARNING Risk of explosion from a fro‐
zen battery
A discharged battery may freeze at tempera‐
tures slightly above or below freezing point.
During starting assistance or battery charg‐
ing, battery gas can be released.
#
Always allow a battery to thaw before
charging it or performing starting assis‐
tance.
If the warning/indicator lamps do not light up in
the instrument display around or below freezing
point, it is very likely that the discharged battery
has frozen.
In this case, observe the following points:
R
Do not give the vehicle starting assistance or
charge the battery
R
The service life of a battery that has been
thawed may be reduced drastically
R
The start-up behavior may deteriorate, partic‐
ularly at low temperatures
R
It is recommended that you have a thawed
battery checked at a qualified specialist work‐
shop

NOTE Damage caused by numerous or
extended attempts to start the engine
Numerous or extended attempts to start the
engine may damage the catalytic converter
due to non-combusted fuel.
#
Avoid numerous and extended attempts
to start the engine.
When jump-starting and charging the batteries,
observe the following points:
R
Only use undamaged jumper cables/charging
cables with a sufficient cross-section and
insulated terminal clamps
R
Non-insulated parts of the terminal clamps
must not come into contact with other metal
parts while the jumper cables/charging
cables are connected to the battery/jump-
start connection point
R
The jumper cables/charging cables must not
come into contact with any parts which may
move when the engine is running
R
Always make sure that neither you nor the
battery is electrostatically charged
R
Always keep away from fire and open flames
R
Do not lean over a battery
R
When charging: only use a battery charger
that has been tested and approved by Freight‐
liner Sprinter and read the operating instruc‐
tions for your charger before charging the
batteries
