Heavy rainfall/snowfall
interferes with the
radar signals
No action required. The system automatically
resets to an unblocked state once the
rainfall/snowfall rate decreases or stops. Do
not use BLIS® and/or CTA in these conditions.
System Limitations
The BLIS® and CTA systems do have their limitations; situations such as
severe weather conditions or debris build-up on the sensor area may
limit vehicle detection.
The following are other situations that may limit the BLIS®:
•
Certain maneuvering of vehicles entering and exiting the blind zone.
•
Vehicles passing through the blind zone at very fast rates.
•
When several vehicles forming a convoy pass through the blind zone.
The following are other situations that may limit the CTA system:
•
Adjacently parked vehicles or objects obstructing the sensors.
•
Approaching vehicles passing at speeds greater than 15 mph
(24 km/h).
•
Driving in reverse faster than 3 mph (5 km/h).
•
Backing out of an angled parking spot.
False Alerts
Note:
If the vehicle has a factory equipped tow bar, and it is towing a
trailer, the sensors will detect the trailer and turn the BLIS off to avoid
false alerts. For non-factory equipped tow bars you may want to turn the
BLIS off manually.
There may be certain instances when either the BLIS® or CTA systems
illuminate the alert indicator with no vehicle in the coverage zone; this is
known as a false alert. Some amount of false alerts are normal; they are
temporary and self-correct.
