If a fault occurs in the adaptive cruise control system, or in any of its features, the instrument panel displays a message. If this occurs, adaptive cruise control does not operate. Consult a retailer/authorized repairer at the earliest opportunity.

Accumulations of dirt, snow, or ice on the radar sensor or cover may inhibit adaptive cruise control operation. Fitting a protector or metalized badges to the front of the vehicle may also affect adaptive cruise control operation. DRIVER INTERVENE, followed by RADAR SENSOR BLOCKED displays in the instrument panel if adaptive cruise control operation is affected in this way. Clearing the obstruction allows the system to return to normal operation. Operation is resumed automatically once the obstruction is removed.

RADAR SENSOR BLOCKED may also display temporarily in the instrument panel if the radar's vision is disrupted. For example, in poor weather conditions, when traveling through a tunnel, or in complex traffic situations.


RADAR SENSOR BLOCKED may also display in the instrument panel when traveling on open roads with few objects for the radar to detect.


Non-recommended tires may have a different circumference to those recommended for this vehicle. Tires with a different circumference can affect the performance and operation of the adaptive cruise control system.
