■When a vehicle is traveling ahead
When a vehicle ahead of yours is detected entering the Traffic Jam Assist detection
area, Traffic Jam Assist adjusts the speed of your vehicle to maintain the selected
interval between your vehicle and the one ah ead. It also applies steering torque to
keep your vehicle in the ce nter of the detected lane.
Keep your vehicle near the center of the lane
while driving.u Traffic Jam Assist will be activated once
the camera has detected the white
(yellow) traffic lane lines on either side of
the lane and the radar sensor and
camera have detected a vehicle driving
ahead.
The dotted outer lines change to solid
ones and a vehicle icon appears on the
multi-information display.
■How Traffic Jam Assist Works1How Traffic Jam Assist Works
If your vehicle veers too far to the right or the left of
the white (yellow) traffic lane lines while Traffic Jam
Assist is active, deactivate Traffic Jam Assist and have
an authorized Acura deal er inspect your vehicle.
In some cases the system cannot properly detect the
traffic lane lines and, as a result, will not provide
steering assistance. 2 Traffic Jam Assist: Conditions and
