On-board diagnostics interface
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 onboard
diagnostics interface.
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 on the on-board diagnostic 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.
