Driving your vehicle
The system will be cancelled when:
You change lanes with the turn sig-nal.
- Using the turn signal to changelanes.
- If you change lanes without the turn signal on, the steering wheel
might be controlled.
LKAS can transit to steering assist mode when the car is near to mid-
dle of the lane after system on or
the lane was changed. LKAS can
not assist steering if the vehicle fol-
lows lane marker too close contin-
uously before transition to steering
assist mode.
The control of ESC (Electronic Stability Control) or VSM (Vehicle
Stability Management) is activated.
The steering will not be assisted when your drive fast on a sharp
curve.
The steering will not be assisted when vehicle speed is below 40
mph (64 km/h) and over 110 mph
(177 km/h).
The steering will not be assisted when you change lanes fast. The steering will not be assisted
when you brake suddenly.
The steering will not be assisted when the lane is very wide or nar-
row.
The steering will not be assisted when only one side lane marker is
detected.

LKAS function change Lane Departure Warning
LDWS alerts the driver with a visual
and acoustic warning when the sys-
tem detects the vehicle leaving the
lane. In this mode, the steering wheel
will not be controlled. When the vehi-
cle’s front wheel contacts the inside
edge of lane line, LKAS issues the
lane departure warning.
Standard LKA
The Standard LKA mode guides the
driver to help keep the vehicle within
the lanes. It rarely controls the steer-
ing wheel, when the vehicle drives
well inside the lanes. However, it
starts to control the steering wheel,
when the vehicle is about to deviate
out of the lanes.
Active LKA
The active LKA mode provides more
frequent steering wheel control in
comparison with the Standard LKA
mode. Active LKA can reduce the dri-
ver’s fatigue to assist the steering for
maintaining the vehicle in the middle
of the lane.
Driving your vehicle
The driver can change LKAS to Lane Departure Warning System (LDWS) or
the LKAS mode between Standard LKA and Active LKA from the User
Settings Mode on the LCD display.
