Land Rover Defender: Adaptive cruise control limitations

Clear front bumper/windshield Driver Assistance feature performance limited may be displayed if adaptive cruise control is in standby and an obstruction is detected over a period of time. If the message is displayed, clear any obstruction (e.g. ice/ mud in front of the manufacturer badge or the windshield).

Seek retailer/authorised repairer assistance if the message persists. The instrument panel may also display Clear front bumper/windshield Driver Assistance feature performance limited temporarily if the radar sensor or camera's vision is disrupted for a long period. For example, in poor weather conditions, when traveling through a tunnel, or in complex traffic situations.

Adaptive cruise control does not operate if:

• Neutral (N), Reverse (R) or Park (P) are selected.
• The speed limiter is in operation.

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

• The CANCEL command is requested.
• The brake pedal is pressed.
• The Anti-lock Braking System (ABS) requests a cruise control cancelation.
• The Electric Parking Brake (EPB) is applied.
• The driver's seat belt is unbuckled.
• Any passenger door is opened.
• An off-road terrain response program is selected.

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

• All Surface Progress Control (ASPC) 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.

ADAPTIVE CRUISE CONTROL DRIVER INTERVENTION

The amount of braking applied by the adaptive cruise control system is limited.

The system sounds an audible warning and the instrument panel displays a message if the system's braking limits are reached. The driver should intervene immediately and apply a higher level of braking force using the brake pedal.

Adaptive cruise control cancels when the brake pedal is pressed, or if the vehicle becomes stationary. Press the RES button on the steering wheel to resume adaptive cruise control operation. Pressing the accelerator pedal inhibits adaptive cruise control braking. The follow mode amber warning lamp extinguishes to confirm the system has been overridden. Adaptive cruise control operation resumes when the accelerator pedal is released.
