Cross Traffic coverage also decreases when parking at shallow angles
(refer to figure for approximate zone coverage areas [sensor
obstructed to vehicle on left]).
CTA Detection Limitations: Due to the nature of radar technology,
there may be certain instances where vehicles entering and exiting the
blind spot zones may not be detected. Below is a list of circumstances
that may cause non detection:
• Debris build up on the rear quarter panel fascias
• The rear quarter panel radar beams are obstructed or partially
obstructed by an adjacently parked vehicle or object.
• Approaching vehicles passing at speeds greater than 15 mph
(24 km/h).
• Severe weather conditions
• Driving in reverse faster than 3 mph (5 km/h).
• Backing out of an angled parking spot.
CTA and Reverse Sensing System (RSS) interaction
CTA works along with the Reverse Sensing System (RSS) (if equipped).
Become familiar with the warning tones of both systems.
