active steering function) tim-
ing will also be changed.
When later is selected, the 
emergency steering assist 
(excluding the active steering 
function) will not operate in most 
cases.
 Vehicles with a driver monitor 
camera: When the system 
determines that the driver is 
not facing forward, the pre-
collision warning and emer-
gency steering assist will 
operate at the earlier timing, 
regardless of the user setting.
 When the dynamic radar 
cruise control is operating, the 
pre-collision warning will 
operate at the earlier timing, 
regardless of the user setting.
 Vehicles with Traffic Jam 
Assist: When the Traffic Jam 
Assist is operating, the pre-
collision warning will operate 
at the earlier timing, regard-
less of the user setting. 
When driving on a road with 
clear lane lines with the 
dynamic radar cruise control 
operating, lane lines and pre-
ceding and surrounding vehi-
cles are detected using the 
front camera and radar sen-
sor, and the steering wheel is 
operated to maintain the vehi-
cle’s lane position.
Use this function only on highways 
and expressways.
If the dynamic radar cruise control 
is not operating, the function will not 
operate.
In situations where the lane lines 
are difficult to see or are not visible, 
such as when in a traffic jam, sup-
port will be provi ded using the path 
of preceding and surrounding vehi-
cles.
If the system determines that the 
steering wheel has not been oper-
ated for a certain amount of time or 
the steering wheel is not being 
firmly gripped, the driver will be 
alerted and this function will be 
temporarily canceled.
If the steering wheel is firmly 
gripped, the f unction will begin 
operating again.
