Adaptive cruise control:

  • Should only be used when conditions are favourable. For example, on major roads with traffic moving in lanes.

  • Should not be used during abrupt or sharp turns. For example, traffic islands, junctions, areas with many parked vehicles, or areas shared with pedestrians.

  • Performance and operation can be affected by the use of non-recommended tyres. Non-recommended tyres may have a different circumference to those recommended for the vehicle.

  • Performance may be inhibited if accumulations of dirt, snow, or ice build up on the radar sensor or camera. Fitting a protector or metalised badges to the front of the vehicle may also affect adaptive cruise control operation.

If the cruise control radar or camera is temporarily blocked when the system is active, Take Control: Cruise Cancelled is displayed in the instrument panel. An alert also sounds.

A warning message may be displayed if adaptive cruise control is in standby and an obstruction is detected over a period of time. If a warning message is displayed, clear the obstruction. Seek retailer/authorised repairer assistance if the message persists.

The instrument panel may also display a warning message temporarily if the radar sensor or camera's vision is disrupted for a long period. For example, in poor weather conditions, when travelling through a tunnel, or in complex traffic situations.

Adaptive cruise control does not operate if:

Adaptive cruise control automatically deactivates, but does not clear its memory, when:

  • The speed control rocker switch is pushed inwards to the CAN position on the steering wheel controls.

  • The brake pedal is pressed.

  • The Anti-lock Braking System (ABS) requests a cruise control cancellation.

  • The Electric Parking Brake (EPB) is applied.

  • The driver's seat belt is unbuckled.

  • Any passenger door is opened.

  • Low range transmission is selected.

  • An off-road terrain response program is selected.

Adaptive cruise control automatically deactivates, and its memory is cleared, when:

  • All Terrain Progress Control (ATPC) is selected.

  • Hill Descent Control (HDC) is selected.

  • The ignition is switched off.

  • A fault occurs in the adaptive cruise control system.

  • The driver's door is opened.
