Re: Approval of new features
Date: April 25, 2002

The following features have recently been approved:

• Power actuated service doors may use a three position door control switch to operate the red warning lamp system and stop arm signal.

This feature will allow independent operation of the service door with the red warning lamps and stop signal arm.

• Step treads in the service door entrance may be heated.
• Interlock system for powerlift controls may be used.

The controls may be interlocked with the vehicle brakes, transmissions or door, or they may provide other appropriate mechanisms or systems to ensure the vehicle cannot be moved when the lift is not stowed and so the lift cannot be deployed unless the interlocks or systems are engaged.
