Infiniti QX: Lane Departure Warning (LDW) system
Precautions on LDW system
WARNING
► This system is only a warning device to
inform the driver of a potential unintended
lane departure. It will not steer
the vehicle or prevent loss of control. It
is the driver’s responsibility to stay
alert, drive safely, keep the vehicle in
the traveling lane, and be in control of
the vehicle at all times.
► The system will not operate at speeds
below approximately 45 MPH (70 km/h)
or if it cannot detect lane markers.
► If the LDW system malfunctions, it will
cancel automatically, and the lane departure
warning light (orange) will illuminate.
► If the lane departure warning light
(orange) illuminates, pull off the road
to a safe location and stop the vehicle.
Turn the engine off and restart the
engine. If the lane departure warning
light (orange) continues to illuminate,
have the system checked by an INFINITI
retailer.
► Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
The system may not function properly
under the following conditions:
► On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-standard
lane markers; or lane markers
covered with water, dirt, snow, etc.
► On roads where the discontinued lane
markers are still detectable.
► On roads where there are sharp curves.
► On roads where there are sharply
contrasting objects, such as shadows,
snow, water, wheel ruts, seams or lines
remaining after road repairs. (The LDW
system could detect these items as
lane markers.).
► On roads where the traveling lane
merges or separates.
► When the vehicle’s traveling direction
does not align with the lane marker.
► When traveling close to the vehicle in
front of you, which obstructs the lane
camera unit detection range.
► When rain, snow or dirt adheres to the
windshield in front of the lane camera
unit.
► When the headlights are not bright due
to dirt on the lens or if the aiming is not
adjusted properly.
► When strong light enters the lane
camera unit. (For example, the light
directly shines on the front of the
vehicle at sunrise or sunset.).
► When a sudden change in brightness
occurs. (For example, when the vehicle
enters or exits a tunnel or under a
bridge.)
LDW system operation
The LDW system provides a lane departure
warning function when the vehicle is driven
at speeds of approximately 45 MPH (70
km/h) and above. When the vehicle
approaches either the left or the right side
of the traveling lane, a warning chime will
sound and the lane departure warning light
(orange) on the instrument panel will blink
to alert the driver.
The warning function will stop when the
vehicle returns inside of the lane markers.
The LDW system is not designed to warn
under the following conditions.
► When you operate the lane change
signal and change traveling lanes in
the direction of the signal. (The LDW
system will become operable again
approximately 2 seconds after the lane
change signal is turned off.).
► When the vehicle speed lowers to less
than approximately 45 MPH (70 km/h).
► When the Blind Spot InterventionTM
system activates an audible warning
or brake control.
After the above conditions have finished
and the necessary operating conditions are
satisfied, the LDW functions will resume.
Turning on or off the LDW system :
The warning systems switch is used to turn on and off the LDW system when it is activated using the settings menu on the center display.
