Cruise Control Engaging Cruise Control The speed control functions of the vehicle management and control (V-MAC) IV system are very similar to the cruise controls found on most automobiles. The system will maintain a set speed and will allow acceleration and deceleration through the system switches. Cruise control can be enabled or disabled using customer data programming, included in the VCADS software. To set the cruise control for normal highway operation, the following conditions must be met. 1 Vehicle road speed must be above the customer-programmable speed value (15 to 35 mi/h). 2 The service and parking brake must not be applied. 3 The clutch must be engaged (pedal released).
