2012 MERCEDES-BENZ SPRINTER battery

Disconnecting the battery
G
Warning
There is a risk of a short circuit if the positive
terminal of the
connected battery comes into
contact with any part of the vehicle. This could
cause the flammable gas mix to ignite. You
and others could be seriously injured.
R Do not place any metal objects or tools on
the batteries.
R When disconnecting the batteries, always
disconnect the negative terminal clamp
before the positive terminal clamp.
R When connecting the batteries, always
connect the positive terminal clamp before
the negative terminal clamp.
R Do not disconnect or connect the batteries
when the engine is running.
! Switch off the engine and remove the key
from the ignition lock before you loosen or
disconnect the terminal clamps. You may
otherwise destroy electronic components
such as the alternator.
Always disconnect the starter battery in the
battery case in the driver's footwell first.
! Always disconnect the battery in
the order described below. Never swap the
terminal clamps. You may otherwise
damage the vehicle electronics.
X Switch off all electrical consumers.
Disconnecting the starter battery
The starter battery is located in the battery
case in the driver's footwell. Removing/installing the floor covering in
the driver's footwell X
To remove: remove screws 008A
and take off
trim 0047.
X Remove floor covering 0046.
X To install: replace floor covering
0046 in the
driver's footwell. G
Warning
Free movement of the pedals must not be
impaired. This would

otherwise jeopardize the
operating and road safety of the vehicle.
Make sure that the floor covering is pushed
under the carrier of the accelerator pedal and
cannot slide between the carrier and the
accelerator pedal when you install it.
This would otherwise prevent you from
depressing the accelerator pedal completely,
thereby restricting your vehicle's
acceleration, e.g. during overtaking.
X Slide floor covering 0046 underneath the
carrier for the accelerator pedal and align
it at the

base of the driver's seat and at the
door sill.
Make sure that the floor covering does not
obstruct the accelerator pedal.
X Put trim 0047 in place and screw the screws
008A back in.176

Charging the battery G
Warning
Only charge the battery in a well-ventilated
area. As the battery is being charged, gases
can escape and generate minor explosions,
which can injure

you and others or may cause damage to the paintwork or acid corrosion on
the vehicle.
There is a risk of acid burns during the
charging process due to the gases which
escape from the battery. Do not, therefore,
lean over the battery while it is being
recharged.
X Recharge the removed battery. Observe
the notes in the operating instructions for
your battery charger.
X Follow the above steps in the reverse order
to install the battery again.
! Only charge the installed battery with a
battery charger that has been tested and
approved by the distributor named on the
inside front cover. This device allows the
battery to be

charged when it is installed in
the vehicle. The vehicle's electronics
system may otherwise be damaged.
i It is also possible to charge the starter
battery using the jump-starting connection
point in the engine compartment
(Y page 247).
Reconnecting the battery !
Always connect the battery in the order
described below. Never

mix up the terminal
clamp disconnection/connection order
and never mix up the terminal clamps. You
may otherwise damage the vehicle
electronics.
X Switch off all electrical consumers.
X Connect the positive terminal clamp.
X Attach the cover to the positive terminal.
X Connect the negative terminal clamp.
i After the battery has been reconnected,
you must reset the side windows
(Y page 61). 178
Maintenance
Operation

Battery care
!
Please always observe the following
notes:
R dirty battery clamps
and battery surfaces
cause leak currents, which lead to the
batteries discharging. Always keep the
battery terminals and battery surfaces
clean and dry. Grease the battery
terminals, particularly the terminal
undersides, with a light coating of acid-
resistant grease.
R cleaning agents containing fuel corrode
the battery housing. Only clean the
battery housing with commercially
available cleaning agents.
R only clean the batteries when the caps
are screwed on. Dirt may otherwise enter
the battery cells and damage the battery.
R the breathers in the caps and the cell
ventilation tubes must be open.
Otherwise, gas cannot escape. Unscrew
blocked breathers and clean them with a
suitable tool such as a piece of wire. If
you do not unscrew the caps for cleaning,
there is a risk of short circuit.
R regularly check the battery terminals and
the fastening of the negative cable to the
chassis to ensure that they are firmly
seated.
R if batteries are not being used, you
should charge them once a month. Maintenance
