Cruise Control – HFV6 Page 8C–3
1 General Information
A new cruise control system has been introduced due to changes in the powertrain architecture and components. There
is no longer a cruise control module; instead the management has been taken over by the engine control module (ECM).
To the user, the system operates as previously, with all controls from the cruise control switch assembly and the cruise
control messages presented by the instrument cluster. For vehicles fitted with the HFV6 engine refer to 1.3 System
Operation .
The cruise control system now has an
additional fail-safe feature. The brake pedal
must be pressed in the ignition cycle for the
cruise control to be engaged. The cruise
control will not engage until this is done.
