THEFT PREVENTION LABELS
(U.S.A.ONLY)
17L002
Your new vehicle carries theft prevention labels which are
approximately 56 mm (2.20 in.) by 16 mm (0.63 in.).
The purpose of these labels is to reduce the incidence of vehicle
thefts by facilitating the tracing and recovery of parts from stolen
vehicles. The label is designed so that once it is applied to a surface,
any attempt to remove it will result in destroying the integrity of the
label. Transferring these labels intact from one part to another will
be impossible.
NOTICE
You should not attempt to remove the theft prevention labels as
it may violate certain state or federal laws.
