The Adaptive Cruise Control (ACC) system is designed to maintain a gap from the vehicle ahead, or a set road speed if there is no slower vehicle ahead. A speed may be set at between 32 km/h (20 mph) and 180 km/h (112 mph).


For vehicles with a 3.0 litre engine, the upper limit is 200 km/h (124 mph).

The system acts by regulating the speed of the vehicle, using engine control and the brakes.


ACC is not a collision warning or avoidance system. Additionally, ACC will not react to:

  • Pedestrians or objects in the roadway.

  • Oncoming vehicles in the same lane.

The ACC system uses a radar sensor, which projects a beam directly forward of the vehicle to detect objects ahead.

The radar sensor is mounted behind the badge in the centre of the front grille, to provide a clear view forward for the radar beam.


Make sure that this area is kept clean and free from obstructions, for example, stickers, debris, mud, snow, ice, etc.

  • Use ACC only when conditions are favourable, i.e., main roads with traffic moving in lanes.

  • Do not use during abrupt or sharp turns, e.g., traffic islands, junctions, areas with many parked vehicles, or areas shared with pedestrians.

  • Do not use in poor visibility, specifically fog, heavy rain, spray or snow.

  • Do not use on icy or slippery roads.

  • It is the driver's responsibility to stay alert, drive safely, and be in control of the vehicle at all times.

  • Keep the front of the vehicle free from dirt, metal badges or objects, including vehicle front protectors, which may prevent the radar sensor from operating.
