Your Land Rover Discovery optionally
incorporates blind spot monitor, or blind
spot assist with closing vehicle sensing,
to provide added assistance when driving
on busy highways and urban roads. This video shows how to get the best from these systems.
The blind spot monitoring system warns the driver of any overtaking vehicle that may not be easily visible.
Blind Spot Assist is an enhancement 
of the blind spot monitoring system.
The feature determines the possible risk of a side collision when a lane change maneuver is initiated.
The additional closing vehicle sensing feature warns the driver of any fast approaching vehicle from behind.
The blind spot monitoring system is an aid only, 
helping you to change lanes more efficiently.
It does not replace the need to correctly 
use the mirrors and to drive safely.
Blind spot monitoring activates when you're traveling forwards at more than six miles per hour.
Before reaching this speed, the system runs a self-check indicated by an amber dot in each of the exterior mirrors.
Blind spot monitoring is most effective
when driving on multi-lane highways.
The area monitored is approximately 20 feet
behind the vehicle and 8.2 feet to
either side, the typical width of a highway lane.
When a vehicle is in your blind spot,
you'll see an amber icon illuminated in
the mirror to the same side as the overtaking vehicle, warning you of the potential danger.
The warning icon will extinguish once the 
overtaking vehicle has passed
The Blind Spot Assist feature activates
when you're traveling forwards at more
than 40 miles per hour. When a lane
change maneuver is made, while a risk is
detected, the amber warning icon 
flashes in the relevant door mirror.
At the same time a rotational force is
automatically applied to the steering
wheel to counter the lane change. The
applied force indicates that a steering
correction should be made to avoid the risk of collision.
The rotational force can still be
overridden to make a lane change.
The closing vehicle sensing feature monitors
a larger area behind the vehicle,
approximately 230 feet, and warns 
you of fast approaching vehicles.
When a vehicle is closing in fast you'll see 
the amber warning icon flashing in the relevant mirror.
It will illuminate continuously once the
vehicle reaches your blind spot. 
Radar sensors in the rear bumper detect
movement. Do not cover the sensors with any
obstructions. For example, stickers. And make sure that
you keep the sensors clear from any dirt
or debris. If a sensor fails, you'll see
the message "blind spot monitor not
available" in the message center.
When a fault occurs in the system,
consult a retailer or authorized repairer.
If you wish to disable blind-spot
monitoring, press the menu button on the
steering wheel, followed by driving assistance. Scroll to
blind spot monitor, using the down arrow
button, and press ok to disable.
When blind spot monitoring is disabled
Blind Spot Assist and closing vehicle
sensing is also disabled. To reactivate
simply repeat this process.
