Object Detection Description and Operation (UFT)
|
The side blind zone alert system is designed to detect vehicles or other objects that may be located in the vehicles blind spots. This detection is performed by two side object sensors, located behind the rear fascia on each side of the vehicle. When an object is detected in a blind spot, an indicator in the outside rearview mirror will illuminate, notifying the driver that it is unsafe to change lanes.
The side blind zone alert system is made up of the following components:
|
•
|
Left side object sensor
|
|
•
|
Right side object sensor
|
|
•
|
Driver outside rearview mirror
|
|
•
|
Passenger outside rearview mirror
|
Side Object Sensors
The side object sensors are each located behind the rear fascia, positioned so that the sensor is pointing out toward the opposite lane. Each sensor is supplied B+ and ground. The right sensor receives an additional ground. Both sensors communicate independently on the serial data line. The serial data enters the left sensor in a pass-thru configuration, that connects to the right sensor. The scan tool is able to communicate with each sensor independently.
When a vehicle or object is detected by a side object sensor, the sensor will illuminate the indicator located in the appropriate outside rearview mirror.
Outside Rearview Mirror
The outside rearview mirrors each contain an indicator that is controlled by the appropriate side object sensor. This indicator is illuminated when a vehicle or object is positioned in the vehicle's blind spot.

Side Blind Zone Alert Operation
|
When the vehicle is started, the indicators located in the outside rearview mirror will briefly illuminate to indicate that the system is operating. The side object sensors cover a zone of approximately one lane over from both sides of the vehicle, 3.5 m (11 ft). This zone starts at each side mirror and goes back approximately 5.0 m (16 ft). The height of the zone is approximately between 0.5 m (1.5 ft) and 2.0 m (6 ft) off the ground. When a vehicle or object is detected in this area, the appropriate indicator will be illuminated, indicating to the driver that it is unsafe to change lanes. If a turn signal is activated while the indicator is illuminated, the indicator will flash as a more urgent warning that a lane change may be unsafe.
Foul weather may affect the operation of the side blind zone alert system. Occasional missed alerts can occur under normal circumstances and will increase in wet conditions. The number of missed alerts will increase with increased rainfall or road spray. Heavy rainfall, as well as mud, dirt, snow, ice, or slush build-up on the rear fascia, will completely disable the system.
If the vehicle is towing a trailer or has an object, such as a bicycle rack, attached to the rear of the vehicle, the side blind zone alert system may not function properly and the indicators will remain illuminated at all time.

SIDE BLIND ZONE ALERT SYSTEM OFF
This message indicates that the system has been disabled through the Vehicle Personalization located in the radio. Refer to the vehicle owners manual for instructions on how to set personalization options on the driver information center.
SIDE BLIND ZONE SYSTEM UNAVAILABLE
This message indicates that the system has been disabled because the sensor is blocked or can otherwise not accurately detect vehicles or objects. Such instances may be mud, dirt, snow, ice, or slush build-up on the rear fascia, heavy rainfall, or excessive road spray.
SERVICE SIDE BLIND ZONE ALERT SYSTEM
This message indicates that the system requires service. When the message is displayed, the indicators will remain illuminated at all times, notifying the driver that the side blind zone alert system should not be relied upon when changing lanes.
