In any gear.
At a specific
manufacture may determine at a specific time that it is
safer to have the vehicles doors lock at 10 mph, as opposed
to last years model that locked at 15 mph.

the dealer may also have access to the same modification
This allows the
consumer to change a specific features and allow the dealer
to add another service to there inventory, as most dealer
may have a small fee for this service.
