2015 MERCEDES-BENZ SPRINTER jump start terminals

Be sure to observe the notes on charging
the batteries (Y
page 263). Installation locations
Your vehicle may be equipped with three bat-
teries, depending on the equipment version:
R a starter battery in the battery case in the
driver's footwell
R additional battery in the engine compart-
ment
R auxiliary battery under the driver's seat
Have the auxiliary battery removed at a quali-
fied specialist workshop. Installing/removing the floor cover-
ing (starter battery) G
WARNING
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
top of one another. X
Switch off all electrical consumers.
X To remove: remove screws 0087and take off
trim 0044. X
Remove floor covering 0043.
X To install: place floor covering 0043in the
driver's footwell.
X Slide floor covering 0043underneath the car-
rier of 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 notobstruct the accelerator pedal.
X Put trim 0044in place and screw screws 0087
back in. 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 260

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 additional 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. Additional battery in the engine compartment
X Switch off all electrical consumers.
X Switch off the engine and remove the key
from the ignition lock.
X Open the hood (Y page 248).
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 and remove the positive terminal
clamp. Connecting the additional battery !
Always connect the battery in the order
described below. Never swap the terminal
clamps. You may otherwise damage the
vehicle electronics.
X Connect the positive terminal clamp.
X Attach the cover to the positive terminal.
X Connect the negative terminal clamp.
X Close the hood.
Carry out the following work after connecting
the battery:
X Reset the side windows (Y page 79). Installing and removing the additional
battery (engine compartment)

WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting. Battery
263Maintenance and care Z

If the indicator/warning lamps do not light up
in the instrument cluster when temperatures
are low, it is probably because the discharged
battery has frozen. Should this be the case, do
not jump-start the vehicle or charge the bat-
tery. The service life of a thawed battery may be shorter. Start-up behavior may deterio-
rate, in particular at low temperatures. Have
the thawed battery checked at a qualified
specialist workshop. G
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 skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten- tion.
! 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.
A battery charger unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an accessory. Only this device permits the
charging of the battery in its installed posi-
tion. Only charge the installed battery with a
battery charger that has been tested and
approved by Mercedes-Benz, using the jump-
start connection point in the engine compart-
ment. Contact an authorized Mercedes-Benz
Center for information and availability. Read the operating instructions for your charger
before charging the battery.
The additional battery can not be charged
from the jump-starting connection point.
Recharge the battery more frequently if you
use the vehicle mainly for short trips and/or
drive at low outside temperatures.
X Charge the battery. Observe the notes in
the operating instructions for your battery
charger.
X If necessary, install battery. Observe the
notes on reconnecting the battery.
i Recharge uninstalled, out of service bat-
teries every three months. This will counter
self-discharging and prevent battery dam-
age. 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 battery casing with a com-
mercially available cleaning product. 264
