The cruise control system is integrated with the engine management system and uses throttle intervention to automatically maintain a set vehicle speed. Once engaged, the system can also be used to accelerate the vehicle without using the accelerator pedal. The cruise control system consists of:
- A master switch.
- SET+ and RES steering wheel switches.
- An interface ECU.
- A warning lamp.

The system also uses:
- Inputs from the brake pedal sensor and the Anti-lock Braking System (ABS) modulator.
- The Engine Control Module (ECM).

The Controller Area Network (CAN) bus is used by the cruise control system for the exchange of data between the interface ECU, ECM, EAT ECU, ABS modulator and instrument pack.

Cruise control is enabled when the master switch is pressed. Once enabled, the cruise control system is operated using the steering wheel switches. The steering wheel switches output signals to the interface ECU, which then signals the ECM. The ECM then adjusts the throttle to maintain the vehicle at the set speed.

The cruise control warning lamp provides a visual indication of when the system is engaged.
