light INFINITI QX50 2021 Owner's Manual

After the above conditions have finished and
the necessary operating conditions are satis-
fied, the LDW functions will resume.
SYSTEM MALFUNCTION
If the LDW system malfunctions, it will cancel
automatically and “Malfunction” will appear
in the vehicle information display. If “Mal-
function” appears in vehicle information dis-
play, pull off the road to a safe location and
stop the vehicle. Place the shift lever in the P
(Park) position and ignition switch in the OFF
position and restart the engine. If “Malfunc-
tion” continues to appear in vehicle informa-
tion display, have the system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
SYSTEM MAINTENANCE
The lane camera unitO1for the LDW system
is located above the inside mirror. To keep the
proper operation of the LDW system and
prevent a system malfunction, be sure to ob-
serve the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar- ent 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 damaged
due to an accident, it is recommended that
you visit an INFINITI retailer.

•The LDP system may activate if you
change 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
following conditions as it may not func-
tion 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 tem-
porary 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 suspen-
sion 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.
• 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 cam-
era 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 signaland change the traveling lanes in the direc-
tion of the signal. (The LDP system will be
deactivated for approximately 2 seconds
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

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 for
proper 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.

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
O1
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, see

UNAVAILABLE
When radar blockage is detected, the system
will be deactivated automatically. The “Un-
available: Side Radar Obstruction” warning
message will appear in the vehicle informa-
tion display.
The system is not available until the condi-
tions no longer exist.
The radar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog. The blocked condition
may also be caused by objects such as ice,
frost or dirt obstructing the radar sensors.
NOTE:

BSI SYSTEM OPERATION
1. Side indicator light
2. BSW indicator3. BSI ON indicator
4. ProPILOT Assist switchThe BSI system operates above approxi-
mately 37 mph (60 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 indicator light
flashes. The side indicator light continues to
flash until the detected vehicle leaves the
detection zone.
If the BSI system is on and your vehicle ap-
proaches a lane marker while another vehicle
is in the detection zone, the system chimes
(three times) and the side indicator light
flashes. The BSI system activates to help re-
turn the vehicle back to the center of the
driving lane. The BSI system operates regard-
less of turn signal usage.
NOTE:
• BSI warning and system application will
only be activated if the side indicator light
is already illuminated when your vehicle
approaches a lane marker. If another ve-
hicle comes into the detection zone after
your vehicle has crossed a lane marker, no
BSI warning or system application will be
activated. For additional information, see
“BSI driving situations” (P. 5-60 ).
