Corrective steering will be indicated with Jf.
If the lane departure warning must intervene
for a long period of time, a message will re-
quest the driver to drive in the center of the
lane. The steering wheel can also vibrate to

warn you if lane boundaries are detected dur-
ing a passing maneuver.
The lane departure warning is ready to provide
warnings if an object is detected on at least one
side of the individual lane.
If the Hi indicator light turns on, the lane depar-
ture warning is not ready to provide warnings.
This may occur due to the following system limits
or situations:
— The necessary lane marker lines have not been
detected (for example, in a construction zone
or because the lines are obstructed by snow,
dirt, water, or lighting)
— The speed is below the activation speed
— The lane is too narrow or too wide
— The curve is too narrow
— The driver's hands are not on the steering
wheel
— Visibility is obstructed by a rise or dip.
Steering intervention request
If the lane departure warning intervenes multiple
times when no steering activity is detected, the
steering intervention request will provide a warn-
ing using audio and visual signals, such as El.
Take over the steering and keep your hands on
the steering wheel so that you will be ready to
steer at any time. The system may no longer be
ready to provide warnings after a short time, and
it will only become active again later.
If the driver does not take over steering, the lane
departure warning will no longer be ready to pro-
vide warnings. If the vehicle is equipped with
emergency assist and it is ready to function, it
will be activated > page 157.
