With the key in steering lock position 2, the 
seat belt warning lamp comes on for a short 
time if the driver’s seat belt is not fastened. 
After starting the engine, the warning lamp remains 
illuminated for a short time to remind the driver and 
passengers to fasten seat belts.
Charge indicator lamp
Should the charge indicator lamp fail to 
come on prior to starting when the key is in 
steering lock position 2 or should it fail to go 
out after starting or during operation, this indicates a 
malfunction which must be repaired at an authorized 
Mercedes-Benz Light Truck Center immediately.If the charge indicator lamp comes on while the engine 
is running, this may indicate that the poly-V-belt has 
broken. Should this condition occur, the poly-V-belt 
must be replaced before continuing to operate the 
vehicle. Otherwise, the engine will overheat due to an 
inoperative water pump which may result in damage to 
the engine.
Do not continue to drive the vehicle with the charge 
indicator lamp illuminated. Doing so could result in 
serious engine damage that is not covered by the 
Mercedes-Benz Limited Warranty.
