2019 INFINITI QX50 Owner's Manual

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the LDP system
could result in serious injury or death.
∙ The LDP system will not steer the vehicleor 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 LDP system is primarily intended for
use on well-developed freeways or high-
ways. It may not detect the lane markers
in certain road, weather, or driving
conditions.
The LDP system will operate when the ve-
hicle is driven at speeds of approximately
37 mph (60 km/h) and above, and only when
the lane markings are clearly visible on the
road.
The LDP system warns the driver with a
warning indicator in the vehicle information
display, the steering wheel will vibrate and
helps assist the driver to return the vehicle to
the center of the traveling lane by applying
the brakes to the left or right wheels individu-
ally (for a short period of time).
The LDP system monitors the lane markers
on the traveling lane using the camera unit
1
located above the inside mirror.

LDP SYSTEM OPERATION
The LDP system operates above approxi-
mately 37 mph (60 km/h). When the vehicle
approaches either the left or the right side of
the traveling lane, the steering wheel will vi-
brate and the LDP indicator (orange) on the
instrument panel will blink to alert the driver.
Then, the LDP system will automatically ap-
ply the brakes for a short period of time to
help assist the driver to return the vehicle to
the center of the traveling lane.
To turn on the LDP system, push the dynamic
driver assistance switch (for vehicles without
ProPILOT Assist) or the ProPILOT Assist
switch (for vehicles with ProPILOT Assist) on
the steering wheel after starting the engine.
The LDP indicator (green) on the instrument
panel will illuminate. Push the dynamic driver
assistance switch (for vehicles without Pro-
PILOT Assist) or the ProPILOT Assist switch
(for vehicles with ProPILOT Assist) on the
steering wheel again to turn off the LDP
system. The LDP indicator will turn off.

LDP SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the LDP system. Failure to follow the warn-
ings and instructions for proper use of the
LDP system could result in serious injury or
death.
∙ The LDP system may activate if youchange lanes without first activating
your turn signal or, for example, if a con-
struction zone directs traffic to cross an
existing lane marker. If this occurs you
may need to apply corrective steering to
complete your lane change.
∙ Because the LDP may not activate under the road, weather, and lane marker con-
ditions described in this section, it may
not activate every time your vehicle be-
gins to leave its lane and you will need to
apply corrective steering.
∙ The LDP system will not operate at speeds below approximately 37 mph
(60 km/h) or if it cannot detect lane
markers.
∙ Do not use the LDP system under the fol- lowing conditions as it may not function
properly: – During bad weather (rain, fog, snow,
etc.).
– When driving on slippery roads, such as on ice or snow.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift or tempo- rary lane.
– When driving on roads where the lane width is too narrow.
– When driving without normal tire conditions (for example, tire wear, low
tire pressure, installation of spare tire,
tire chains, non-standard wheels).
– When the vehicle is equipped with nonoriginal brake parts or suspension
parts.
– When you are towing a trailer or other vehicle.
The system may not function properly un-
der the following conditions: ∙ On roads where there are multiple paral-
lel 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 mark- ers are still detectable.
∙ On roads where there are sharp curves.
∙ On roads where there are sharply con- trasting objects, such as shadows, snow,
water, wheel ruts, seams or lines remain-
ing after road repairs. (The LDP 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.
Starting and driving5-41

∙ When the headlights are not bright dueto 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 sun-
rise or sunset.)
∙ When a sudden change in brightness oc- curs. (For example, when the vehicle en-
ters or exits a tunnel or under a bridge.)
While the LDP system is operating, you may
hear a sound of brake operation. This is nor-
mal and indicates that the LDP system is
operating properly.
SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
The warning and assist functions of the LDP
system are not designed to work under the
following conditions: ∙ When you operate the lane change signal and change the traveling lanes in the di-
rection of the signal. (The LDP system will
be deactivated for approximately 2 sec-
onds after the lane change signal is
turned off.) ∙ When the vehicle speed lowers to less
than approximately 37 mph (60 km/h).
After the above conditions have finished and
the necessary operating conditions are satis-
fied, the warning and assist functions will
resume.
Condition B:
The assist function of the LDP system is not
designed to work under the following condi-
tions (warning is still functional): ∙ When the brake pedal is depressed.
∙ When the steering wheel is turned as far as necessary for the vehicle to change
lanes.
∙ When the vehicle is accelerated during LDP system operation.
∙ When the Intelligent Cruise Control (ICC) approach warning occurs.
∙ When the hazard warning flashers are operated.
∙ When driving on a curve at high speed.
After the above conditions have finished and
the necessary operating conditions are satis-
fied, the LDP system application of the
brakes will resume. Condition C:
If the following messages appear in the ve-
hicle information display the LDP system will
be turned off automatically:
∙ “Not Available Poor Road Conditions”: When the VDC system (except Traction
Control System [TCS] function) or ABS
operates.
∙ “Currently not available”: When the VDC system is turned off.
Action to take:
When the above conditions no longer exist,
turn off the LDP system. Push the dynamic
driver assistance switch (for vehicles without
ProPILOT Assist) or the ProPILOT Assist
switch (for vehicles with ProPILOT Assist) on
the steering wheel again to turn the LDP
system back on.
Temporary disabled status at high temperature:
If the vehicle is parked in direct sunlight under
high temperature conditions (over approxi-
mately 104°F [40°C]) and then the LDP sys-
tem is turned on, the LDP system may be de-
activated automatically and the following
message will appear on the vehicle information
display: “Not available: High Camera Temp.”
5-42Starting and driving

When the interior temperature is reduced, the
system will resume operating automatically.
SYSTEM MAINTENANCE
The lane camera unit1for the LDP system
is located behind the inside mirror. To keep
the proper operation of the LDP system and
prevent a system malfunction, be sure to ob-
serve the following:
∙ Always keep the windshield clean.
∙ Do not attach a sticker (including trans- parent material) or install an accessory
near the camera unit. ∙ Do not place reflective materials, such as
white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers.
∙ Do not strike or damage the areas around the camera unit. Do not touch the camera
lens or remove the screw located on the
camera unit. If the camera unit is dam-
aged due to an accident, it is recom-
mended that you visit an INFINITI re-
tailer.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the BSW system
could result in serious injury or death.
∙ The BSW system is not a replacement forproper driving procedures and is not de-
signed to prevent contact with vehicles
or objects. When changing lanes, always
use the side and rear mirrors and turn and
look in the direction your vehicle will
move to ensure it is safe to change lanes.
Never rely solely on the BSW system.
The BSW system helps alert the driver of
other vehicles in adjacent lanes when chang-
ing lanes. The BSW system uses radar sensors
1in-
stalled near the rear bumper to detect other
vehicles in an adjacent lane. The radar sensors can detect vehicles on ei-
ther side of your vehicle within the detection
zone shown as illustrated. This detection
zone starts from the outside mirror of your
vehicle and extends approximately 10 ft
(3.0 m) behind the rear bumper, and approxi-
mately 10 ft (3.0 m) sideways.

1. Side Indicator Light
2. BSI/BSW/BCI/RCTA Indicator
BSW SYSTEM OPERATION
The BSW system operates above approxi-
mately 20 mph (32 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light
1
illuminates. If the turn signal is then activated,
the system chimes (twice) and the side indi-
cator light flashes. The side indicator light
continues to flash until the detected vehicle
leaves the detection zone.
The side indicator light illuminates for a few
seconds when the ignition switch is placed in
the ON position.
The brightness of the side indicator light is
adjusted automatically depending on the
brightness of the ambient light.
If a vehicle comes into the detection zone
after the driver activates the turn signal, then
only the side indicator light flashes and no
chime sounds. For additional information, re-
fer to “BSW driving situations” in this section.
