Land Rover Defender: Lane keep assist (LKA)

Make sure the relevant safety warnings have been read and understood before driving the vehicle.

Note: Make sure the LKA system is disabled when connecting a trailer.

Lane Keep Assist (LKA) monitors the road lane markings in the event of an unintentional road lane departure. If the vehicle is about to cross a lane boundary, a rotational force is applied to the steering wheel to counter the lane boundary crossing. The instrument panel displays a warning icon when a rotational force is applied to the steering wheel.

Note: The LKA system does not assist the driver if road lane markings tracking is not available.

The Lane Keep Assist (LKA) system can be switched on and off via the driver assistance button (1). The button icon illuminates green when the LKA system is switched on.

Note: The driver assistance button (1) also controls operation of the Blind Spot Assist (BSA) system.

Note: The LKA system selection is retained in the vehicle's memory after the vehicle is switched off.

The instrument panel displays an icon when the LKA system is switched on. The icon changes color as follows:

• Gray lines indicates:
  • The lane boundaries are not being tracked.
  • The driver is indicating on the same side.

    Note: When indicating left, the left side only is grayed out. The same strategy applies when indicating right.

  • One or more of the system limitations criteria may have been met.
• Green lines indicate that the lane boundaries are being tracked.
• Red lines indicate when the LKA feature is intervening.

LKA status can also be viewed via the Driver Assistance instrument panel view.

The Driver Assistance view displays a visual representation of the vehicle's position within a lane in the instrument panel. The lane boundaries change the same color as the icon:

• Gray
• Green
• Red

Note: The Head-Up Display (HUD) also displays a warning.

LANE KEEP ASSIST (LKA) LIMITATIONS

The Lane Keep Assist (LKA) system is not active when:

• Reverse (R) or Park (P) is selected.
• The brake pedal is pressed.
• A turn signal is being used.
• The road lanes are not available or in poor condition.
• The road lane markings are not detected.
• The vehicle's speed is approximately below 40 mph (64 km/h) or above 112 mph (180 km/h).
• Driving in lanes narrower than approximately 10 ft (3 m) or wider than approximately 13 ft (4 m).
• Turning in tight road bends.
• Dynamic Stability Control (DSC) is active.
• Anti-lock Braking System (ABS) is active.
• A fault occurs in the system.

The LKA system does not operate if:

• The windshield area in front of the rear-view mirror becomes blocked by stickers, mud, snow, or debris.
• Adverse weather conditions exist. For example, heavy fog, rain, or snow.
• The driver has applied a counter steering input that is greater than the steering input from the LKA system.

The instrument panel displays messages to inform the driver of any performance or system issues.

Note: If a system fault has been detected with the instrument panel or Head-Up Display (HUD), the LKA continues to operate as intended.
