Dodge 2005 Viper - Manual (Page 70)

WARNING!
Adjusting a seat while the vehicle is moving is
dangerous. If you are driving, the sudden movement
of the seat could cause you to lose control. You could
be injured. Adjust any seat only while the vehicle is
parked. Do not ride with the seatback reclined so
that the shoulder belt is no longer riding against
your chest. In a collision you could slide under the
seat belt and be seriously or even fatally injured. Use
the recliner only when the vehicle is parked.
