220 Customer information
When using the vehicle, situations
may occur in which these technical
data related to other information
(accident report, damages on the
vehicle, witness statements etc.) may
be associated with a specific person -
possibly, with the assistance of an
expert.
Additional functions contractually
agreed upon with the client (e.g.
vehicle location in emergency cases)
allow the transmission of particular
vehicle data from the vehicle.
Radio Frequency
Identification (RFID)
RFID technology is used in some
vehicles for functions such as tyre
deflation detection and ignition
system security. It is also used in
connection with conveniences such
as radio remote controls for door
locking/unlocking and starting, and in-
vehicle transmitters for garage door
openers. RFID technology in Opel
vehicles does not use or record
personal information or link with any
other Opel system containing
personal information.
