If LDW is on, the LDW indicator will
appear green if the system detects
a left or right lane marking while the
vehicle is travelling at 56 km/h (35
mph) or greater. If the vehicle
crosses a detected lane marking
without using the indicator in the
lane departure direction, this
indicator will change to amber and
flash. In addition, three beeps will
be sounded from the left or right
side, or the Safety Alert Seat will
pulse three times on either the left
or right side of the seat, depending
on the lane departure direction.
When the System Does Not
Seem to Work Properly
If the LDW symbol does not appear
when the system is on and the
vehicle is travelling at least 56 km/h
(35 mph):
The lane markings on the road
may not be seen.
The camera sensor may be
blocked by dirt, snow, or ice.
The windscreen may be
damaged.
The weather may be limiting
visibility.
This is normal operation; the vehicle
does not need service.
Lane markings may not be detected
on bends, motorway exit ramps,
or hills; or due to poor visibility.
If the LDW camera system does not
seem to operate properly, cleaning
the outside of the windscreen in
front of the camera sensor may
correct the issue.
Warning
LDW does not provide a warning
to help avoid a crash, unless it
detects the lane markings. LDW
may not detect the lane markings
if the camera sensor is blocked
by dirt, snow, or ice, or if the
windscreen is damaged. It may
also not detect a lane on winding

or hilly roads, or in conditions that
can limit visibility such as fog,
rain, or snow, or if the headlamps
or windscreen are not cleaned or
in proper condition. Keep the
windscreen, headlamps, and
camera sensors clean and in
good repair.
LDW warnings may occur due to tar
marks, shadows, cracks in the road,
or other road imperfections. This is
normal system operation; the
vehicle does not need service.
