2014 MERCEDES-BENZ SPRINTER jump start terminals

Disconnecting/connecting the
starter battery
Important safety notes G
WARNING
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.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
R Never place metal objects or tools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables.
R Never 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 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 dam-
age the vehicle electronics. Battery cover in the driver's footwell
X Switch off all electrical consumers.
X Switch off the engine and remove the key
from the ignition lock.
X Remove the floor covering in the driver's
footwell ( Ypage 261).
X Loosen screws 0044and slide battery
cover 0043in the direction of the arrow.
The screws must protrude beyond the
larger recesses.
X Remove battery cover 0043upwards. Starter battery in the driver's footwell
X First loosen and remove the negative ter-
minal clamp so that it is no longer in contact
with the terminal.
X Remove the cover from the positive termi-
nal.
X Loosen the positive terminal clamp and fold
it up to the side together with the pre-fuse

WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery. G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention.
! Only charge the installed battery with a
battery charger that has been tested and
approved by the distributor named on the
inside of the front cover. This device allows
the battery to be charged when it is instal- led in the vehicle. The vehicle's electronics
may otherwise be damaged.
X Recharge the removed battery. Observe
the notes in the operating instructions for
your battery charger.
X Install the battery. Observe the notes on
reconnecting the battery.
i If batteries are not being used, you should
charge them once a month.
It is also possible to charge the starter bat-
tery using the jump-starting connection
point in the engine compartment
(Y page 278). Care
! Dirty battery clamps and battery surfaces
cause leak currents which lead to the bat-
teries discharging.
! Do not use cleaning agents containing
fuel. Cleaning agents containing fuel cor-
rode the battery housing.
! If dirt gets into the battery cell, battery
self-discharge will increase and the battery
may be damaged.
The following points on battery care must be
observed:
X Regularly check the battery terminals and
the fastening of the negative cable to the
chassis to ensure that they are firmly
seated.
X Always keep the battery terminals and bat-
tery surfaces clean and dry.
X Lightly grease the undersides of the battery
terminals with acid-resistant grease.
X Only clean the batteries when the caps are
screwed on.
Otherwise, dirt could get into the battery
cells.
X Unscrew the caps and clean blocked
breathers with a suitable tool such as a
piece of wire. 266
