uuWhen Driving uTraffic Jam Assist
Driving
Traffic Jam Assist
The traffic jam assist system uses a radar se nsor 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 line s as well as any vehicle ahead. Based on
inputs from the radar sensor and camera, the system adjusts the speed of your
vehicle to maintain a set interval betwee n your vehicle and the one detected ahead.
It also applies steering torque to keep your 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 Control with Low Speed Follow is
active, the traffic jam assist system, upon de tecting 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.
