Notes on changing bulbs

Bulbs and lamps are an important aspect of vehicle safety. You must therefore make sure that all bulbs are in working order at all times.

../../../../global/pictures_mb/symb_achtung.png

WARNING

Bulbs and lamps can be very hot. You should therefore allow them to cool down before you change them. Otherwise, you could be burned if you touch them.

Keep bulbs out of the reach of children. Otherwise, they could damage the bulbs, for example, and injure themselves.

Never use a bulb which has been dropped. Such a bulb may break or even explode and injure you.

Halogen bulbs are pressurised and can explode when you change them, particularly if they are very hot. You should therefore wear eye protection and gloves when you are changing them.

  • Switch off the lighting system before changing a bulb to avoid a short-circuit.

  • Only touch new bulbs with a clean lint-free cloth or similar. Do not work with wet or greasy fingers.

  • Only fit 24 V bulbs of the same type and of the correct wattage.

    Vehicles with halogen load compartment lighting:

    For the load compartment lighting, only fit 12 V bulbs of the same type as before and of the correct wattage.

  • Have the headlamp setting checked regularly.

  • If the new bulb still does not light up, consult a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.

Make sure the bulbs are always securely fitted.

Fuses

../../../../global/pictures_mb/symb_info.png

Blown fuses must be replaced with fuses of the same rating (which can be recognised by the colour and amperage) and which have the amperage specified in the fuse allocation chart. More information can be obtained from any Mercedes-Benz Service Centre.

../../../../global/pictures_mb/symb_achtung.png

WARNING

Only use fuses that have been approved for Mercedes-Benz vehicles and which have the correct fuse rating for the systems concerned. Do not attempt to repair or bridge faulty fuses. Otherwise, a circuit overload could cause a fire. Have the cause traced and rectified at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.

../../../../global/pictures_mb/symb_info.png

Always carry spare fuses in the vehicle for emergencies.

Switch off the ignition and the electrical consumers before changing a fuse.

Fuse box

The fuses, relays and spare fuses (24 V) are located in the fuse box in the glove compartment.

../../../../global/pictures_mb/symb_info.png

The following fuses are located in the seat base:

  • F56 - F58 (12 V) for the ABS hydraulic assembly and the charge indicator

  • F60 (24 V) for the battery isolating switch and emergency shutdown

  • F61 (24 V) for the auxiliary heating system

images/img09fba6ee351f1514167ce066313ad7cf_1_--_--_JPG72.jpgGlove compartment open

To open: open the glove compartment more.

Turn quick release fastener mbsymb6_inv_003b.png about 90° using a suitable object, e.g. a coin and remove cover mbsymb6_inv_003a.png.

To close: make sure that quick release fastener mbsymb6_inv_003b.png is turned so that it is horizontal. Fit the bottom of cover mbsymb6_inv_003a.png and fold up.

Turn quick release fastener mbsymb6_inv_003b.png about 90° and lock cover mbsymb6_inv_003a.png.

Fuse allocation

The fuse allocation chart for standard equipment fuses and relays is on the front of cover mbsymb6_inv_003a.png; the fuse allocation chart for optional equipment fuses is on the reverse of the cover. Both charts show all numbered fuses and relays.

Power supply for auxiliary consumers

../../../../global/pictures_mb/symb_ruf.png

Observe the following points when retrofitting additional electrical consumers:

  • Do not connect additional consumers to fuses which are already allocated.

  • Do not connect additional cables to existing ones (e.g. using an insulation piercing connecting device).

  • Use additional fuses to ensure that retrofitted electrical consumers have adequate fuse protection.
