Traffic Jam Assist
The traffic jam assist system uses a radar sensor mounted inside the front grille and
a camera mounted to the upper portion of the windshield to detect and monitor left
and right white (yellow) traffic lane lines as well as any vehicle ahead. Based on
inputs from the radar sensor and camera, the system can adjust the speed of your
vehicle to maintain a set interval between your vehicle and the one detected ahead.
It also can apply steering torque to keep yo ur vehicle in the center of the detected
lane when you are driving in heavy traffic.
■How Traffic Jam Assist works
If you are in heavy traffic and Adaptive Cruise Contro l with Low Speed Follow is
active, the traffic jam assist system, upon detecting the traffic lane lines and a vehicle
ahead, will apply steering torque to help keep your vehicle in the center of the lane.
The system adjusts the speed of your vehicl e to maintain a set interval between your
vehicle and the one detected ahead.

area, Traffic Jam Assist adju sts the speed of your vehicle to maintain the selected
interval between your vehicle and the one ahead. It also applies steering torque to

■Canceling Traffic Jam Assist1How Traffic Jam Assist Works
If you are traveling slower than the vehicle detected
ahead or a vehicle that is de tected cutting in front of
you and the interval betw een your vehicle and the
detected vehicle gradually increases, your vehicle will
continue to follow that ve hicle without emitting any
warning, even if the interv al between the vehicle is
minimal.

km/h), Traffic Jam Assist is deactivated and LKAS is
activated instead. Once the speed of the vehicle
drops to under 40 mph (64 km/h), Traffic Jam Assist
is reactivated.

• The Cross Traffic Monitor is turned on.
2 Cross Traffic Monitor On and Off P. 504
•The transmission is in (R.
• Your vehicle is moving at 3 mph (5 km/h) or
lower.
When a vehicle is detected approaching from a rear corner, Cross Traffic Monitor
alerts you with a buzzer and a displayed warning.
The system will not detect a vehicle that approaches from directly behind your
vehicle, nor will it provide alerts about a detected vehicle when it moves directly
behind your vehicle.
The system does not provide alerts for a vehicle that is moving away from your
vehicle, and it may alert for pedestrians, bicycles, or stationary objects.
■How the System Works1 Cross Traffic Monitor*
Cross Traffic Monitor may not detect or may delay
alerting an approach ing vehicle, or may alert without
an approaching vehicle under the following
conditions:
•An obstacle, such as a nother vehicle and a wall,
near your vehicle’s rear bumper, is blocking the
radar sensor’s scope.
•Your vehicle is moving at the speed of about 3 mph
(5 km/h) or higher.
•A vehicle is approaching at the speed other than
between about 6 mph (10 km/h) and 16 mph (25
km/h).
•The system picks up external interference such as
other radar sensors from an other vehicle or strong
radio wave transmitted fr om a facility nearby.
•Either corner of the rear bumper is covered with
snow, ice, mud or dirt.
•When there is bad weather.
•Your vehicle is on an incline.
•Your vehicle is tilted due to a heavy load in the rear.•Your vehicle is reversing towards a wall, a pole, a
vehicle, and so on.
•The rear bumper or the sensors have been
improperly repaired or the rear bumper has been
deformed.
Have your vehicle checked by a dealer.
