Socket for OBD Onboard
Diagnosis
An OBD socket for testing components that are
critical to exhaust composition is located under
a cover on the driver's side.
Emissions values
▷
The warning lamp lights up:
The emissions values are deterio‐
rating. Have the vehicle checked as
soon as possible.
▷
The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period can
seriously damage emission control compo‐
nents, in particular the catalytic converter.
Display of the previously described mal‐
functions on Canadian models.
Fuel cap
The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that fuel
vapor is escaping. If the cap is then tightened,
the display should go out in a short time.
Data memory
Your vehicle records data relating to vehicle op‐
eration, faults and user settings. These data are
stored in the remote control and can be read out
with suitable devices, particularly when the ve‐
hicle is serviced. The data obtained in this way
provide valuable information for service proc‐
esses and repair or for optimizing and develop‐
ing vehicle functions further. In addition, if you
signed a service contract for Assist, certain ve‐
hicle data can be sent directly from the vehicle
to facilitate the desired services.
