2023 Land Rover Defender Collision Avoidance
COLLISION AVOIDANCE SAFETY
Make sure the following warnings and notes have been read and fully understood before driving the vehicle. Failure to use the collision avoidance systems safely could result in an accident, leading to serious injury or death.
- Collision avoidance systems are not a substitute for driving safely, with due care and attention. Staying alert, driving safely, and being in control of the vehicle at all times is the responsibility of the driver.
- Blind spot driving aids are a supplement to, not a replacement for, a safe driving style.
- The driver is responsible for driving with due care and attention, and in a safe manner for the vehicle, the occupants, and other road users. The driver is responsible for detecting obstacles, and estimating the vehicle’s distance from them, when manoeuvring the vehicle. The driver should observe all road signs, road markings and any potential braking situations, and act appropriately.
- Always use the door and rear-view mirrors. Drive safely at all times, and use the door and rear-view mirrors to help avoid accidents.
- Blind spot driving aids may not function at all speeds, or in all weather conditions.
- Blind spot driving aids do not correct errors of judgement when driving.
- The radar and camera sensors used by the blind spot driving aids may become impaired by mud, rain, frost, ice, snow, or road spray. The blind spot driving aids ability to detect a vehicle in the driver’s blind spot may subsequently be affected and may give false indications.
- Do not attach stickers or objects to the rear bumper or to the windscreen. Operation of the blind spot sensors and camera may subsequently become impaired. The blind spot driving aids ability to detect a vehicle in the driver’s blind spot may subsequently be affected and may give false indications.
- Do not attach stickers or other objects to the door mirrors, as the blind spot icons and indicators may become obscured. Obscuring the icons and indicators could increase the risk of a collision during a vehicle manoeuvre.
- The blind spot monitor system may not be able to give adequate warning of vehicles approaching very quickly from behind.
- The blind spot monitor system may not be able to detect all vehicles and may also detect objects such as roadside barriers.
- Do not use blind spot assist when a trailer is connected. The trailer may provide miscalculations or false indications. False indications could increase the risk of a collision during a vehicle manoeuvre.
- The radar sensor must be calibrated if it is replaced, its mounting is replaced, or it becomes misaligned, e.g., as a result of impact damage. Contact a retailer/authorised repairer.
The radar sensor is approved for use in all member countries covered under the Radio and Telecommunications Terminal Equipment (RTTE) directive.
FORWARD ALERT
Make sure the relevant safety warnings and notes have been read and understood before driving the vehicle. See COLLISION AVOIDANCE SAFETY.
Forward alert may not react to slow-moving vehicles. Always drive with due care and attention. Driving without due care and attention greatly increases the risk of an accident.
The driver is recommended to switch off the forward alert system when driving off-road, using a car wash, or when the vehicle is being towed.
Forward alert monitors an area in front of the vehicle. The driver is warned if forward alert detects an object within the detection area. The instrument panel also displays a warning message if the vehicle is travelling between 30 km/h (18 mph) and 80 km/h (50 mph). The driver is responsible for taking appropriate action.
Four forward alert sensitivity settings are available:
- Off
- Very Early
- Early
- Normal.
Warnings sound and the instrument panel displays a warning message if forward alert detects an object in front of the vehicle.
Additionally, haptic alerts are used to notify the driver if forward alert detects an object in front of the vehicle.
Forward alert can be switched on or off and the sensitivity settings can be adjusted via the Driver Assistance menu. See CHANGING THE FORWARD ALERT SENSITIVITY.
CHANGING THE FORWARD ALERT SENSITIVITY
Forward alert has four different sensitivity settings. The default setting is Normal.
If required, the sensitivity of the forward alert feature can be changed. To change the sensitivity settings, complete the following steps:
- Touch the settings icon from any screen. See SYSTEM SETTINGS.
- Select Vehicle.
- Select Driver Assistance.
- Select Collision avoidance.
- Touch to select the required setting:
Off
Very Early
Early
Normal.
The forward alert sensitivity setting is retained in the vehicle’s memory after the vehicle is switched off.
AUTONOMOUS EMERGENCY BRAKING (AEB) SAFETY
Make sure the following warnings and notes have been read and fully understood before driving the vehicle. Failure to understand the Autonomous Emergency Braking (AEB) system could result in an accident, leading to serious injury or death.
- The AEB system is a driving aid only. The driver is responsible for driving with due care and attention, and in a safe manner for the vehicle, the occupants, and other road users. The driver should observe all road signs, road markings and any potential emergency braking situations, and act appropriately.
- The AEB system uses forward-facing cameras and forward-facing radars to detect real vehicles and pedestrians, plus other certified target objects. AEB is not designed to detect any other objects, including non-industry approved targets.
- In order for AEB to operate, it must be able to detect a clear image of the object and be able to determine its movement. If neither of these occur, the AEB system may not operate.
- Seat belts should be worn by all vehicle occupants, for every journey, no matter how short. Failure to do so greatly increases the risk of death or serious injury in the event of sudden braking or an accident.
- Make sure that the windscreen is kept clean and that the camera’s line of sight is not obstructed by labels or stickers. Failure to do so can cause incorrect AEB operation.
AEB efficiency is dependent on the condition of the current driving surface and the vehicle’s speed, tyres, and braking system.
When a vehicle is parked outside, in full sunlight and in high ambient temperatures, the forward-facing camera may reach an internal temperature of 99°C (210°F). In this state, the instrument panel displays a warning message. When the forward-facing camera cools to less than 88°C (190°F), normal operation is resumed, and the warning message extinguishes.
When the vehicle’s electrical system is first switched on, AEB may require an initialisation period before it is fully functional. AEB efficiency is limited during this period.
AUTONOMOUS EMERGENCY BRAKING (AEB)
Make sure the relevant safety warnings and notes have been read and understood before driving the vehicle. See AUTONOMOUS EMERGENCY BRAKING (AEB) SAFETY.
Not all vehicles are fitted with Autonomous Emergency Braking (AEB). Consult a retailer/authorised repairer for confirmation.
The driver is recommended to switch off the AEB system when driving off-road, when using a car wash, or when the vehicle is being towed.
AEB uses forward-facing cameras, located above the rear-view mirror, and forward-facing radars, located on the front bumper, to help identify an imminent risk of collision with:
- Another vehicle travelling in front.
- An oncoming vehicle from adjacent lane while host vehicle turning left or right.
- A crossing pedestrian.
- A pedestrian moving in the same direction as the vehicle.
- An oncoming pedestrian from opposite direction while host vehicle turning left or right.
- A crossing cyclist.
- A cyclist travelling in the same direction as the vehicle.
- An oncoming cyclist from opposite direction while host vehicle turning left or right.
In most instances, AEB helps reduce the severity of an impact. In some cases, AEB helps to stop the vehicle before an impact takes place.
AEB automatically switches on, every time the vehicle’s electrical system is switched on.
If required, the AEB feature can be switched off via the touchscreen. To switch AEB off, complete the following steps:
- Touch the settings icon from any screen. See SYSTEM SETTINGS.
- Select Vehicle.
- Select Driver Assistance.
- Select Collision avoidance.
- Emergency braking: Touch to switch the toggle on or off.
AEB operates at speeds above 5 km/h (3 mph).
The vehicle detection AEB system can detect:
- Vehicles travelling in the same road lane of speeds up to 130 km/h (80 mph).
- Vehicles travelling in the adjacent road lane of speeds up to 64 km/h (39 mph). The system only detects other vehicles when host vehicle is turning left or right, with a speed of up to 20 km/h (12 mph).
The pedestrian and cyclist detection AEB systems are able to operate at speeds of up to 60 km/h (37 mph).
If an imminent risk of a collision is detected, the system automatically applies the brakes. The instrument panel also displays a warning message while AEB is operating.
If AEB brings the vehicle to a stop, the brakes continue to hold the vehicle stationary for a few seconds. After this period, the driver must resume full control of the vehicle. Failure to take back full control of the vehicle could result in an accident, leading to serious injury or death.
The brake lights are automatically operated in heavy braking situations.
The distance required to slow or stop the vehicle is dependent on the condition of the vehicle’s tyres and the road surface.
The driver can override AEB operation by turning the steering wheel, or pressing the accelerator pedal. When overridden, AEB cancels its request for braking to make sure that the driver remains in full control of the vehicle.
After AEB has been activated, a warning sounds and the instrument panel displays a warning message.
AUTONOMOUS EMERGENCY BRAKING (AEB) LIMITATIONS
Vehicle detection Autonomous Emergency Braking (AEB) does not operate if:
- The vehicle is negotiating a tight corner.
- The forward-facing cameras are dirty or obscured.

ADVANCED EMERGENCY BRAKE ASSIST (AEBA)
Make sure the relevant safety warnings and notes have been read and understood before driving the vehicle. See COLLISION AVOIDANCE SAFETY.
Advanced Emergency Brake Assist (AEBA) prepares the braking system if it detects a collision is imminent. If the driver subsequently presses the brake pedal, full braking force is applied immediately.
AEBA still operates if forward alert is switched off.
ADVANCED EMERGENCY BRAKE ASSIST (AEBA) LIMITATIONS
Make sure the following warnings have been read and fully understood before driving the vehicle. The Advanced Emergency Brake Assist (AEBA) feature does not take away the requirement to always drive with due care and attention. Driving without due care and attention could result in an accident, leading to serious injury or death.
The AEBA feature may not react to slow-moving vehicles.
The AEBA feature does not react to vehicles travelling in the opposite direction.
In some circumstances, warnings may not display in the instrument panel. For example, if the distance to the vehicle ahead is very small. Another example includes when carrying out a collision avoidance manoeuvre by making large steering wheel and pedal movements.
AEBA operates at speeds above approximately 8 km/h (5 mph).
The distance required to slow or stop the vehicle is dependent on the condition of the vehicle’s tyres and the road surface.
BLIND SPOT MONITOR
Make sure the relevant safety warnings and notes have been read and understood before driving the vehicle. See COLLISION AVOIDANCE SAFETY.
