Problem Possible cause/result Suggested solutions
The battery check lamp on the remote control
for the auxiliary heating does not light up
briefly when a button is pressed.
The remote control batteries are discharged. Change the remote control batteries
( page 541).
The auxiliary heating does not switch on or the
engine does not start.
Lack of fuel.
The fuel tank is less than a quarter full. The aux-
iliary heating switches off automatically.
Refuel at the nearest refueling station.
Then start the auxiliary heating repeat-
edly until the fuel lines are full.
The undervoltage protection circuit integrated
in the control unit switches off the auxiliary
heating because the on-board voltage is less
than 10 V.
If necessary, have the alternator and
the battery checked.
The fuse has blown. Replace the fuse ( page 589).
Have the cause of the blown fuse
checked at an authorized Sprinter Deal-
