122 UNDERSTANDING YOUR INSTRUMENT PANELHEA TER BOOSTER
The switch (1) for activating the
heater booster system is located in
the center section of the dashboard.
The heater booster system can be
switched on while the vehicle is
being driven to help the engine to
reach its normal operating
temperature more quickly, which
will help to heat up the passenger compartment as
quickly as possible when the heating is switched on.To switch on with the engine running:
Press switch (1), the indicator lamp (2) lights up.
To switch off:
Press switch (1) again or switch the engine off. The
heater booster will then switch to run-on mode (about
2minutes).
NOTE: When the vehicle is being driven and a coolant
temperature of over 185 °F (+80 °C) is reached, the
heater booster system will switch to regulation mode.
If the coolant temperature drops to below 167 °F
(+75 °C) with the heater booster system switched on,
heat output is increased again.
If the key is turned to position 0 in the ignition lock
(run-on for about 2 minutes), the last setting selected at
switch (1) is retained when the engine is restarted
(memory function).
The operation of the heater booster system is usually
not required at outside temperatures above 41 °F
(+5 °C).

AUXILIARY HEATER – WATER OR AIR HEATER
(OPTIONA L)
NOTE: The auxiliary heater (water or air heating
device) can be used whether or not the engine is
running.
The auxiliary heater should be run at least once a
month for about 10 minutes.
The maximum heating period is 120 minutes. For more
information, refer to "Switching the Auxiliary Heater
On and Off - Ignition On".
The auxiliary heater will automatically switch off if the
fuel level is under about 4 US gal (15 l).
In case of faults, refer to "Auxiliary Heater – Tips for
Coping with Problems".
WARNING!
The auxiliary heating must not be operated at gas
stations due to the risk of fire and explosion. For
this reason, switch off the auxiliary heating before
refuelling.
Auxiliary heaters emit fumes when in operation,
including carbon monoxide.
Inhaling carbon monoxide is a health hazard and
can result in unconsciousness and death.
For this reason, do not operate auxiliary heating in
enclosed spaces without ventilation or an
extractor system, e.g. in a garage. Otherwise you
could endanger yourself and others.
WARNING!
Vehicles for transporting hazardous goods:
Observe the relevant safety regulations.

Otherwise there is a risk of severe personal
injuries, death and property damage due to
explosion.
WARNING!
Vehicles with air heater:
For safety reasons, we strongly recommend that
the heat exchanger be replaced by an authorized
Sprinter Dealer after 10 years of use.
If the vehicle is sold, the owner is required to
inform the buyer of this requirement. This should
be done when the Operator’s Manual is
transferred to the buyer.
