The Adaptive Cruise Control (ACC) system is designed to aid the driver to maintain a gap from the vehicle ahead or a set road speed if there is no slower vehicle ahead.


ACC is not a substitute for driving safely, with due care and attention. ACC may not function properly under all weather and road conditions.

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

ACC is not a collision warning or avoidance system and driver’s should not assume that this feature will correct errors of judgement while driving.

Additionally, ACC will not react to:

  • Stationary or slow moving vehicles below 6 mph (10 km/h).

  • 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 lower grille, to provide a clear view forward for the radar beam.

  • Only use ACC when conditions are favorable (i.e., main roads with free flowing traffic).

  • Do not use during abrupt or sharp turns, e.g., 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 sensor from operating.

  • Do not use ACC when entering or leaving a highway.
