OPERATION 109
CRUISE AND ENGINE SPEED CONTROL
With vehicle management and control (V-MAC) IV, the operator has the ability to precisely
control engine speed (RPM) and set cruise control speeds, as well as setting the engine low
idle speed. These functions are performed by using the speed control switches located on the
dashboard. Instructions for setting cruise control and engine speed control are given on the
following pages. For an explanation of engine low idle adjustment, refer to V-MAC® IV
Vehicle Management and Control with Co-Pilot® Display Operator’s Guide..

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 24 – 56
kph (15 to 35 mph).
2 The service and parking brake must not be applied.
3 The clutch must be engaged (pedal released).
