On-board diagnostics interface

G
WARNING
If you connect equipment to the on-board
diagnostics interface, it can affect the
operation of the vehicle systems. This can
impair the operating safety of your vehicle
while driving. There is a risk of accident.
Do not connect any equipment to the on-
board diagnostics interface.
G
WARNING
Loose equipment or equipment cables which
are connected to the on-board diagnostics
interface can obstruct the area around the
pedals. The equipment or the cables could get
between the pedals in the event of sudden
braking or acceleration. You may then no
longer be able to brake, operate the clutch or
accelerate as intended. There is a risk of
accident.
Do not attach any equipment or cables in the
driver footwell.
Connecting equipment to the on-board
diagnostics interface can lead to emissions
monitoring information being reset. This may
lead to the vehicle failing to meet the
requirements at the next special emissions
test or main inspection.
If the engine is switched off and equipment
which is connected to the on-board
diagnostics interface is used, the starter
battery may discharge.
The on-board diagnostics interface is only
intended for the connection of diagnostic
equipment at a qualified specialist workshop.
