Lane Departure

Warning (LDW)

If equipped, LDW may help avoid
crashes due to unintentional lane
departures. It may provide a
warning if the vehicle is crossing a
lane without using a turn signal in
the lane departure direction. LDW
uses a camera sensor to detect the
lane markings. It only operates at
speeds of 56 km/h (35 mph) or
greater.
When the vehicle crosses a
detected lane marking, the LDW
indicator will flash and three beeps
will be sounded from the left or right
side, depending on the lane
departure direction. LDW will not
warn if the turn signal is on in the
departure direction, or if a sharp
maneuver is made.
Warning
The LDW system is an aid to help
the vehicle stay in the driving
lane. It does not steer the vehicle.
The LDW system may not:
Provide enough time to avoid
a crash.
Detect lane markings under
bad weather conditions or if
the windshield is dirty.
Detect lane markings and will
not detect road edges.
Warn that the vehicle is
crossing a lane marking if the
system does not detect the
lane marking.
Warning (Continued)
If LDW only detects lane
markings on one side of the road,
it will only warn you when
departing the lane on the side
where it has detected a lane
marker. Even with LDW, always
keep your attention on the road
and maintain proper vehicle
position within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield clean and do not use
LDW in bad weather conditions.
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
