uuAcuraWatchTMuTraffic Jam Assist
Driving
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 line s as well as any vehicle ahead. Based on
inputs from the radar sensor and camera, th e system can adjust the speed of your
vehicle to maintain a set interval betwee n 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 Control 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.
1 Traffic Jam Assist
3WARNING
Improper reliance on Traffic Jam Assist can
cause a crash resulting in injury or death.
Always maintain full control over your
vehicle even when this system is active. and
only use when on expressways or freeways.
Traffic Jam Assist is not an autonomous
driving system.
3WARNING
Failure to securely park vehicle when
stopped while Adaptive Cruise Control with
Low Speed Follow is active can allow the
vehicle to roll away, resulting in a crash
causing injury or death.
Never stop the vehicle and exit it without
placing it in Park and setting the parking
brake.
