2013 MERCEDES-BENZ SPRINTER auxiliary battery

Problem Possible causes/consequences and
0004 Solutions
The auxiliary heating
switches off
automatically and/or
cannot be switched on. The low-voltage protection system integrated in the control unit
switches off the auxiliary heating because the on-board voltage is
less than 10 V.
X Have the alternator and battery checked. The auxiliary heating
switches off
automatically and/or
cannot be switched on. The fuse is blown.
X
Replace the fuse; see the "Fuse allocation" supplement.
X Have the cause of the blown fuse determined at a qualified
specialist workshop. The auxiliary heating
switches off
automatically and/or
cannot be switched on. A malfunction has occurred.
X
Switch the ignition on and off twice.
If the auxiliary heating still cannot be switched on, the heating
device is faulty.
X Have the auxiliary heating checked at a qualified specialist
workshop. The auxiliary heating is
overheated. The coolant level is too low.
X
Check the coolant level and add more coolant if necessary
(Y page 244). Operating the cargo compartment air
vents
If your vehicle is equipped with a roof
ventilator, you can ventilate and extract air
from the cargo compartment. X
Turn the key to position 2in the ignition
lock.
X To activate and extract air: press the
upper section of the 0009switch.
The roof ventilator removes used air from
the cargo compartment.
X To activate and ventilate: press the lower
section of the 0010switch.
The roof ventilator feeds fresh air into the
cargo compartment.
X To switch off: set the switch to the middle
position. Operating the cargo compartment air vents

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 possible. 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 (Y page 26). Breaking-in notes
The first 1,000 miles (1,500 km)
New or replaced brake pads and brake disks
only reach their optimum braking effec tafter
100 miles (a few hundred kilometers). Until
then, compensate for this by applying greater
force to the brake pedal.
For the service life and economy of your
vehicle it is crucial that you brea kinthe
engine with due care.
R Therefore, protect the engine for the first
1,000 miles (1,500 km) by driving at
varying vehicle and engine speeds.
R Avoid overstraining the vehicle and high
engine speeds during this period, e.g.
driving at full throttle. Do not exceed 0001of
the maximum speed for each gear.
R Do not change down a gear manually in
order to brake.
R Try to avoid depressing the accelerator
pedal beyond the point of resistance
(kickdown).
R The shift ranges 3,2or 1should only be
engaged when driving slowly, e.g. when
driving in mountainous terrain.
After 1,000 miles (1,500 km), you can
increase the engine speed gradually and
accelerate the vehicle up to full speed.
i You should also observe these notes on
breaking-in if the engine or parts of the drive train on your vehicle have been
replaced. Driving
Important safety notes
G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect.Y ou will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident .Release
the parking brake fully before driving off. Battery isolating switch
Important safety notes !
Make sure that the key is in position 0in
the ignition lock and wait at least
20 seconds before disconnecting or
connecting the battery isolating switch.
You could otherwise damage electrical
system components.
You can use the battery isolating switch to
disconnect the power supply to all your
vehicle's consumers. This will prevent
uncontrolled battery discharge caused by off-
load curren tconsumption.
If your vehicle is equipped with an auxiliary
battery in the engine compartment, you will
need to disconnect both batteries. Only then
is the electrical system fully disconnected
from the power supply. 132

Important safety notes G
WARNING
During the charging process, a battery
produces 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
contact with vehicle parts.
R Never place metal objects or tools on a
battery.
R It is important that you observe the
described 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
disconnecting 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 loosenor
disconnec tthe terminal clamps. You may
otherwise destroy electronic components
such as the alternator.
Always disconnectt he starter battery in the
battery case in the driver's footwell first.

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
