DiagnosDiagnostics connectiontics connection

The diagnostics connection is a technical inter-

face in the vehicle. It is used, for example, in the

context of repair and maintenance work or for

reading out vehicle data in a specialist workshop.

Diagnostic devices should therefore only be con-

nected in a qualied specialist workshop.

WARNINGARNING Risk of accident due to con-

necting devices to the diagnostics con-

nection

If you connect devices to the diagnostics con-

nection of the vehicle, the function of vehicle

systems and operating safety may be

impaired.

For safety reasons, we recommend that

you only use and connect products

approved by your authorized Mercedes-

Benz Center.

General notes

WARNINGARNING 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 oor mats securely

and as prescribed in order to ensure that

there is always sucient room for the

pedals.

Do not use loose oor mats and do not

place oor mats on top of one another.

NOOTETE Battery discharging from using devi-

ces connected to the diagnostics connec-

tion

Using devices at the diagnostics connection

drains the battery.

Check the charge level of the battery.

If the charge level is low, charge the bat-

tery, e.g. by driving a considerable dis-

tance.

Please also note the information about the 12 V

battery and short-distance trips in the "Driving

and Parking" chapter (/ page 134).

Connecting and using another device with the

diagnostics connection can have the following

eects:

Malfunctions in the vehicle system

Permanent damage to vehicle components

Please refer to the warranty terms and conditions

for this matter.

Moreover, connecting equipment to the diagnos-

tics connection can lead to emissions monitoring

information being reset, for example. This may

lead to the vehicle failing to meet the require-

ments of the next emissions inspection during the

main inspection.
