BLIS aids you in detecting vehicles that
may have entered the blind spot zone (A).
The detection area is on both sides of the
vehicle, extending rearward from the
exterior mirrors to approximately 10 feet
(3 meters) beyond the bumper. The
system alerts you if certain vehicles enter
the blind spot zone while driving.
Cross traffic alert warns you of vehicles
approaching from the sides when the
transmission is in R (Reverse).
Note: BLIS is not designed to prevent
contact with other vehicles or objects; or to
detect parked vehicles, people, animals or
infrastructure (fences, guardrails, trees,
etc.). It is designed to alert the driver to
vehicles in the blind zones.
Note: When a vehicle passes quickly
through the blind zone, typically fewer than
two seconds, the system does not trigger.
Using the Systems
BLIS turns on when the engine is started
and the vehicle is driven forward above 5
mph (8 km/h); it remains on while the
transmission is in D (Drive) and N
(Neutral). If shifted out of D (Drive) or N
(Neutral), the system enters cross traffic
alert mode. Once shifted back into D
(Drive), BLIS turns back on when the
vehicle is driven above 5 mph (8 km/h).
Driving Aids
Note: BLIS does not function in R (Reverse)
or P (Park) or provide any additional
warning when a turn signal is on.
Note: Cross traffic alert detects
approaching vehicles from up to 45 feet (14
meters) away though coverage decreases
when the sensors are blocked. Reversing
slowly helps increase the coverage area and
effectiveness.
Note: For manual transmission vehicles,
CTA will be active only if the transmission
is in Reverse. If the vehicle is rolling
backwards and the transmission is not in
Reverse then CTA will not be active.

space. Cross traffic alert is not a
replacement for careful driving and only
an assist.
