\3 Auxiliary heating/ventilation*The auxiliary heating heats or ventilates
the interior to a temperature that you
have set. The auxiliary heating can be
operated with the engine switched on or
off.
The auxiliary heating is equipped with a
water heater.
Warning
G
Exhaust fumes are produced while the aux-
iliary heating is in operation. For this rea-
son, switch off the auxiliary heating in
enclosed spaces without an extraction sys-
tem, e.g. a garage.
Operation of the auxiliary heating system is
prohibited at gas stations or when refueling
your vehicle. The auxiliary heating must
therefore be switched off at refueling sta-
tions.
Warning
G
Observe the relevant safety regulations in
the case of vehicles used for the transport
of hazardous goods.
Aerosols, gas cartridges and other pressur-
ized containers transported in the vehicle
may be highly flammable and could explode
when heated.
Make sure that the containers described
are kept away from the flow of hot air from
the auxiliary heating.
Otherwise, you could endanger yourself
and others.

The auxiliary heating heats the coolant
and the vehicle interior and is therefore
more favorable to the engine and con-
sumes less fuel. The fuel tank must be at
least a quarter full to ensure that the
auxiliary heating/ventilation operates
correctly.
The maximum heating period is
60 minutes.
You can use the auxiliary heating / ven-
tilation to:\4

You can use the operating system to de-
fine up to three switch-on times, one of
which can be selected to switch on the
auxiliary heating / ventilation
(
\2
page 240).You can switch the auxiliary heating /
ventilation on and off immediately using:
\4
the auxiliary heating / heater booster
switch (

\4
the auxiliary heating remote control*
(\2
page 239)
iThe auxiliary heating automatically
switches to heater booster mode af-
ter the engine is started.
!
CAUTION
Switch on the auxiliary heating at reg-
ular intervals (at least once a month)
for approximately 10 minutes.
Make sure that the hot air flow is not
obstructed. The auxiliary heating
would otherwise overheat and switch
off.

Fuel is highly flammable. Fire, naked
flames and smoking as well as the use of
auxiliary heaters (sparks) are therefore
prohibited when handling fuel.
For this reason, switch off the auxiliary
heating when refueling.
Warning

with your skin or clothing. Your health
may be damaged if:
\4you spill fuel onto your bare skin

\3 Changing the batteriesIf the remote control batteries (remote
keyless entry) are discharged, you will
only be able to lock and unlock the vehi-
cle manually using the key.
If the batteries in the auxiliary heating
remote control are discharged, you will
only be able to switch the auxiliary heat-
ing on or off using the auxiliary heating /
heater booster switch inside the vehicle
(\2
page 238).
It is advisable to have the batteries
changed at an authorized Sprinter Deal-
er.
Warning
G
Keep batteries away from children.
Consult a doctor immediately if a battery
is swallowed.
Dispose of used batteries in an environ-
mentally responsible manner.
Danger of explosion if the battery is not
correctly replaced.
Replacements should always be either of
the same type or one which has been rec-
ommended by the manufacturer.
Environmental note
H
Batteries contain materials that can harm
the environment if disposed of improper-
ly. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
