Radio Frequency
Identification (RFID)
RFID technology is used in some
vehicles for functions such as tyre
pressure monitoring 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
Vauxhall vehicles does not use or
record personal information or link
with any other Vauxhall system
containing personal information.
