Mercedes-Benz C-Class Owners Manual: Diagnostics connection

The diagnostics connection is only intended for the connection of diagnostic devices at a qualified specialist workshop

WARNING Risk of accident due to connecting devices to the diagnostics connection
If you connect equipment to a diagnostics connection in the vehicle, it may affect the operation of vehicle systems.

As a result, the operating safety of the vehicle could be affected.

  • Only connect equipment to a diagnostics connection in the vehicle which is approved for your vehicle by Mercedes- Benz.

 

WARNING Risk of accident due to objects in the driver's footwell
Objects in the driver's footwell may impede pedal travel or block a depressed pedal.

This jeopardizes the operating and road safety of the vehicle.

  • Stow all objects in the vehicle securely so that they cannot get into the driver's footwell.
  • Always install the floor mats securely and as prescribed in order to ensure that there is always sufficient room for the pedals.
  • Do not use loose floor mats and do not place floor mats on top of one another.

 

NOTE Battery discharging from using devices connected to the diagnostics connection
Using devices at the diagnostics connection drains the battery.
  • Check the charge level of the battery.
  • If the charge level is low, charge the battery, e.g. by driving a considerable distance.

Connecting equipment to the diagnostics connection can lead to emissions monitoring information being reset, for example. This may lead to the vehicle failing to meet the requirements of the next emissions inspection during the main inspection.
