2011 INFINITI QX Owners Manual

The Lane Departure Warning (LDW)
system/Lane Departure Prevention (LDP) sys-
tem will operate when the vehicle is driven at
speeds of approximately 45 MPH (70 km/h) and
above, and when it is traveling close to either
the left or the right of a traveling lane.
Each system functions as follows:
●Lane Departure Warning (LDW) system —
warns the driver by a warning light and
chime.
● Lane Departure Prevention (LDP) system —
warns the driver by a warning light and
chime, and helps assist the driver to return
the vehicle to the center direction of the
traveling lane by applying brake control to
the left or right wheels individually (for a
short period of time). The LDW and LDP systems monitor the lane
markers on the traveling lane using the camera
unit
1located inside the front map light cover.
When the camera unit detects that the vehicle is
traveling close to either the left or the right of
the traveling lane, the lane departure warning
light on the instrument panel blinks in orange
and a warning chime sounds. When the LDP
system is on, it will automatically apply the
brakes for a short period of time, using the
function of the Vehicle Dynamic Control (VDC)
system.

SYSTEM
Precautions on LDW system
WARNING
● This system is only a warning device to in-
form the driver of a potential unintended
lane departure. It will not steer the vehicle or
prevent loss of control. It is the driver’s re-
sponsibility 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 can-
not detect lane markers.

5-20Starting and driving

●If the LDW system malfunctions, it will can-
cel 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 loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the lane departure
warning light (orange) continues to illumi-
nate, have the system checked by an INFINITI
retailer.
● Excessive noise will interfere with the warn-
ing 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 mark-
ers are still detectable.
● On roads where there are sharp curves. ●
On roads where there are sharply contrast-
ing 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 depar-
ture 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 signaland change traveling lanes in the direction of
the signal. (The LDW system will become
operable again approximately 2 seconds af-
ter the lane change signal is turned off.)
– When the vehicle speed lowers to less than approximately 45 MPH (70 km/h).
After the above conditions have finished and
the necessary operating conditions are satis-
fied, the LDW functions will resume.
Turning on or off the LDW system (Type A) :
The LDW system is automatically turned on
when the engine is started and the warning
systems ON indicator light
1illuminates on
the warning systems switch. You can turn the
LDW system off by pushing the warning sys-
tems switch on the instrument panel. This
switch will turn on and off the LDW, BSW and
FCW systems at the same time. NOTE:
If you continue to push the warning systems
switch from off to on for over 4 seconds, a chime
will sound. This will change the default status of
the LDW, BSW and FCW systems to OFF so that
these systems will not automatically turn on
when the engine is started. If this procedure is
repeated, the default status will return to ON.
Turning on or off the LDW system (Type B) :
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.
See “How to enable/disable the LDW system
using the settings menu (Type B)” later in this
section.
When the warning systems switch is turned off,
the indicator
1on the switch is off. The
indicator will also be off if the LDW, the Blind
Spot Warning (BSW) and the Forward Collision
Warning (FCW) systems are deactivated.
For the BSW and FCW systems, see “BLIND
SPOT WARNING (BSW) SYSTEM” later in this
section and “FORWARD COLLISION WARNING
(FCW) SYSTEM” later in this section.

LANE DEPARTURE PREVENTION (LDP)
SYSTEM
Precautions on LDP system
WARNING
●The LDP system will not steer the vehicle or
prevent loss of control. It is the driver’s re-
sponsibility to stay alert, drive safely, keep
the vehicle in the traveling lane, and be in
control of vehicle at all times.
● The LDP system is primarily intended for use
on well-developed freeways or highways. It
may not detect the lane markers in certain
roads, weather or driving conditions.
● Using the LDP system under some condi-
tions of road, lane marker or weather, or
when you change lanes without using the
lane change signal could lead to an unex-
pected system operation. In such condi-
tions, you need to correct the vehicle’s direc-
tion with your steering operation to avoid
accidents.
● When the LDP system is operating, avoid
excessive or sudden steering maneuvers.
Otherwise, you could lose control of the
vehicle. ●
The LDP system will not operate at speeds
below approximately 45 MPH (70 km/h) or if
it cannot detect lane markers.
● The LDP system may not function properly
under the following conditions, and do not
use the LDP system:
– During bad weather (rain, fog, snow, wind, etc.).
– When driving on slippery roads, such as on ice or snow, etc.
– When driving off-road such as on sand or rock, etc.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift lane.
– When driving on roads where the lane width is too narrow.
– When driving without normal tire condi- tions (for example, tire wear, low tire
pressure, installation of spare tire, tire
chains, non-standard wheels).
– When the vehicle is equipped with non- original brake parts or suspension parts.
– When towing a trailer or other vehicle. ●
If the LDP system malfunctions, it will cancel
automatically. The lane departure warning
light (orange) on the instrument panel will
illuminate.
● If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the warning light
(orange) continues to illuminate, have the
LDP system checked by an INFINITI retailer.
● Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
The functions of the LDP system (warning and
brake control assist) may or may not operate
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 discontinued lane markers
are still detectable.
