Blind Spot Monitor (BSM)

CAUTION: Ensure that the warning indicators in the exterior mirrors are not obscured by stickers or other objects.

CAUTION: Do not attach stickers or objects to the rear bumpers that may interfere with the radar sensors.
The purpose of the blind spot monitoring system is to detect an object moving with a positive velocity relative to the radar module, on either side of the vehicle, at a distance of up to 2.5 meters laterally and in an area from the door mirror up to 6.0 meters behind the module. These criteria identify an overtaking vehicle within the blind-spot area and within a typical carriageway lane width, or a vehicle which is being overtaken slowly, while eliminating other objects that are not relevant because of their position, they are stationary, or traveling in the opposite direction. A vehicle is classed as a heavy goods vehicle, car or motorcycle. A motorcycle is defined as a minimum size of 2.0m long, 0.8m wide (widest point) and 1.1m high. The system is not affected by the mass of the overtaking vehicle providing all identification criteria, including the host vehicle's speed must be (16km/h - 10mph) or above, is met.
The system emits radar pulses and analyses the reflections, identifying anything that moves into the blind spot zone. Having detected another vehicle in the defined blind spot zone it alerts the driver by illuminating the amber alert icon located in the appropriate exterior mirror.

NOTE:
If an overtaking vehicle is detected on both sides of the vehicle simultaneously, the warning alert icons in both mirrors will illuminate.









The Blind Spot Monitor (BSM) system monitors a zone that covers the area adjacent to the vehicle that is not easily visible by the driver and is designed to identify any object overtaking the vehicle (3). The system uses radars on each side of the vehicle to identify any overtaking vehicle/object within the blind spot area of the vehicle, while disregarding other objects which may be stationary or travelling in the opposite direction, etc.
If an object is identified by the system as being an overtaking vehicle/object, an amber warning indicator icon (1) illuminates in the relevant exterior mirror, to alert the driver that there is a potential hazard in the vehicle's blind spot and therefore, that a lane change might be dangerous.

NOTE:
This radar sensor is approved in all RTTE countries.

NOTE:
The system covers an area of a fixed lane width. If the lanes are narrower than a typical carriageway lane, objects travelling in non-adjacent lanes may be detected.
The amber warning indicator dot (2) remains illuminated until forward vehicle speed exceeds 16km/h (10mph).
BSM is designed to work most effectively when driving on multi-lane highways.

NOTE:
If an overtaking vehicle is detected on both sides of the vehicle simultaneously, the warning icons in both mirrors will illuminate.

NOTE:
BSM is automatically turned off when reverse (R) gear is selected, when the vehicle is in park (P), the vehicle is travelling below 10km/h (6mph). Under these conditions, the warning indicator dot in the exterior mirrors is displayed.

The LED (light emitting diode) lighting sequence
The LED (light emitting diode) lighting sequence is as follows:
- Amber alert LED (light emitting diode) icon permanently lit - system operational, vehicle detected in blind spot area
- No LED (light emitting diode) is lit - system active no vehicle detected in blind spot area
- Amber status LED (light emitting diode) permanently lit - system not active or faulty

The system operating limitations
The system has operating limitations and is automatically turned off under certain operating conditions. During these operating conditions the amber status LED (light emitting diode)'s permanently lit.
The system operating limitations are as follows:
- The area surrounding the radar face of the module must be clear of metallic items
- The system is inactive until vehicle speed is greater than 16km/h - 10mph (amber status LED (light emitting diode) permanently lit)
- The system is inactive if an approved trailer is connected to the vehicle (amber status LED (light emitting diode) permanently lit)
- The system is inactive when reverse gear or park is selected (amber status LED (light emitting diode) permanently lit)
If either of the radar signals is distorted by water, or if the radar face of the module is covered in mud, sleet or snow, the system may detect this and be disabled with the amber status LED (light emitting diode) permanently lit together with a 'blind spot monitoring blocked' message displayed in the instrument cluster message center. The system is disabled until the blockage is cleared.
If there is a fault in the system the amber status, LED (light emitting diode) is permanently lit and a 'blind spot monitoring not available' message displayed in the instrument cluster message center. The system is disabled until the fault is rectified.

System fault and blockage warnings
System fault and blockage warnings are as follows:
- The system is disabled when the radar module signal is blocked (amber status LED (light emitting diode) permanently lit and instrument cluster message)
- The system is disabled by a fault (amber status LED (light emitting diode) permanently lit and instrument cluster message)
If there is a failure in the communication network and the warning LED (light emitting diode)'s cannot be displayed in the mirror, a failure message will be displayed in the instrument cluster message center.
When any faults are present in the system DTC (diagnostic trouble code)'s are stored in both blind spot monitoring modules appropriate to each module. Replacement of modules requires the right hand module to be configured using the Land Rover approved diagnostic equipment. Due to the fact that all modules are supplied as left hand modules, the replacement left hand modules do not require configuring.
Calibration of the modules using the Land Rover approved diagnostic equipment enables updates to be downloaded as new technology becomes available or any fault concerns require software updates.
