BLIND SPOT INFORMATION SYSTEM
WITH TRAILER COVERAGE
WHAT IS BLIND SPOT INFORMATIONSYSTEM WITH TRAILER COVERAGE
Blind spot information system detectsvehicles that may have entered the blindspot zone. The detection area is on bothsides your vehicle and trailer, extendingrearward from the exterior mirrors to the endof your trailer.
BLIND SPOT INFORMATION SYSTEMWITH TRAILER COVERAGELIMITATIONS
Trailer coverage only supports conventionaltrailers. The system turns off if you select afifth wheel trailer type.
Make sure the trailer width is less than orequal to 8.5 ft (2.6 m) and the length is lessthan 33 ft (10.1 m). If you input values higher,the system turns off.
Some trailers could cause a slight change insystem performance:
•Large box trailers could cause false alertsto occur when driving next toinfrastructures or near parked cars. Afalse alert could also occur while makinga 90-degree turn.
•Trailers that have a width greater than8.5 ft (2.6 m) at the front and have a totallength greater than 20 ft (6 m) couldcause delayed alerts when a vehicle ispassing at high speeds.
•Box trailers that have a width greater than8.5 ft (2.6 m) at the front could causeearly alerts when you pass a vehicle.
•Clam shell or v-nose box trailers with awidth greater than 8.5 ft (2.6 m) at thefront could cause delayed alerts when avehicle traveling the same speed as yourvehicle merges lanes.

WHAT IS CROSS TRAFFIC ALERT
The system alerts you of vehiclesapproaching from the sides behind yourvehicle when you shift into reverse (R).
HOW DOES CROSS TRAFFIC
ALERT WORK
Cross traffic alert detects vehicles thatapproach at a speed between 4–37 mph(6–60 km/h). Coverage decreases when thesensors are partially, mostly or fullyobstructed.
The sensor on the left-hand side is onlypartially obstructed and zone coverage onthe right-hand side is maximized.
Zone coverage also decreases when parkingat narrow angles. The sensor on the left-handside is mostly obstructed and zone coverageon that side is severely reduced.
Note: Slowly reversing helps increase thecoverage area and effectiveness.
CROSS TRAFFIC ALERT
PRECAUTIONS
WARNING: Do not use the crosstraffic alert system as a replacement forusing the interior and exterior mirrors orlooking over your shoulder beforereversing out of a parking space. The crosstraffic alert system is not a replacement forcareful driving.
WARNING: The system may notoperate properly during severe weatherconditions, for example snow, ice, heavyrain and spray. Always drive with due careand attention. Failure to take care mayresult in a crash.
