When the blockage is removed, the system
can be reset in two ways:
• when at least two objects are detected
while driving, or
• turn the ignition from on to off, then back
on.
If the blockage is still present after the key
cycle, the system senses again that it is
blocked after driving in traffic.

radar decreases or stops. Do not
signals use BLIS or cross traffic alert
in these conditions.
System Limitations
The BLIS and cross traffic alert systems do
have their limitations; situations such as
severe weather conditions or debris build-up
on the sensor area may limit vehicle
detection.
226
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 cross traffic alert 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 5 mph
(8 km/h).
• Backing out of an angled parking spot.
False Alerts
Note: If a trailer is connected to the vehicle
the BLIS system may detect the trailer
causing a false alert. You may want to turn
the BLIS off manually.
