138 UNDERSTANDING YOUR INSTRUMENT PANELAUXILIARY HEATER – TIPS FOR COPING WITH
PROBLEMSNOTE: After three successive attempts to start the
heater, a malfunction will be recorded in the integrated
diagnostic system and no further operation on
auxiliary heater will be available (lock-out). The work
to annul the lock-out must be carried out at an
authorized Sprinter Dealer.
The heater either does not switch on or automatically
switches off:
Insufficient fuel, fill up the fuel tank. Start up heater two times, until the fuel lines are filled.
The auxiliary heater will automatically switch off if the fuel level is under about 4 US gal (15 l).
The fuses in the fuse box are damaged. Electric fuses.
The battery voltage is too low, an undervoltage protector switches off the heater if the battery
voltage falls below about 10 volts. The heater motor does not run
The battery voltage is too low, check the battery.
Batteries.
The fuses in the fuse box are damaged. Electric fuses.
The heater motor is damaged.
Overheating The air channels are clogged. The heater can be restarted once the fault has been
repaired. When this is done, the heater should be
switched on and off.
The heater will remain switched off after it has been overheated a number of times (about 10 times in
succession). Have the fault repaired by an
authorized Sprinter Dealer.
NOTE: Repairs should only be made by an authorized

238 MAINTAINING YOUR VEHICLEPlastic and Rubber PartsDo not use oil or wax on these parts.
Do not use any caustic or alcohol-based or solvent-
based substances to clean plastic surfaces.
Avoid the use of stain removers, iodine tincture, nail
varnish and nail varnish remover, acetone, methylated
spirits, chlorine or ammonium-based cleaning agents,
cleaning agents containing abrasive substances.ELECTRICAL FUSESDamaged fuses are recognizable from their burnt-out
filament.
Prior to exchanging a fuse, turn the key in the ignition-
column lock to the 0 position and switch off the
consumer involved.
NOTE: Fuses must not be bridged. Replace fuses with
specified rated current. Only replace fuses when the
cause of the malfunction has been rectified.
NOTE: Fuses and relays (standard equipment) are on
the underside of the ignition column, refer to "Fuses
and Relays Standard Equipment". Fuses, relays and diodes (optional equipment) are
below the driver’s seat, refer to "Optional Fuse and
Relay Equipment".
CAUTION!
When replacing a blown fuse, it is important to
use only a fuse having the correct amperage
rating. The use of a fuse with a rating other than
indicated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected.
