Maintenance and repair should be performed
by your service center. Make sure to have reg‐
ular maintenance procedures recorded in the

nance.
Socket for OBD Onboard
Diagnosis
Socket for Onboard Diagnosis
The socket for Onboard Diagnosis may
only be used by the service center, by work‐
shops that operate according to the specifica‐
tions of the vehicle manufacturer with appro‐
priately trained personnel, and by other
authorized persons. Otherwise, its use may
lead to vehicle malfunctions.◀
On the driver's side is an OBD socket for
checking the primary components in the vehi‐
cle emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as
possible.▷The warning lamp flashes under certain
circumstances:
This indicates that there is excessive mis‐
firing in the engine.Reduce the vehicle speed and have the
system checked immediately; otherwise,
serious engine misfiring within a brief pe‐
riod can seriously damage emission con‐
trol components, in particular the catalytic
converter.
Display of the previously described
malfunctions on Canadian models.
Fuel cap The indicator lamp lights up.
If the fuel cap is not properly tight‐
ened, 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.
