2021 INFINITI QX50 brake light

•Do not use the LDW 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, nonstandard
wheels).
– When the vehicle is equipped with
non-original brake parts or suspen-
sion parts.
– When you are towing a trailer or
other vehicle. 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 contrast- ing objects, such as shadows, snow, water,
wheel ruts, seams or lines remaining after
road repairs. (The LDW system could de-
tect 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, dirt or an object adheres to the windshield in front of the lane cam-
era unit.
• When the headlights are not bright due to dirt on the lens or if the aiming is not ad-
justed 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 oc- curs. (For example, when the vehicle enters
or exits a tunnel or under a bridge.)
SYSTEM TEMPORARILY
UNAVAILABLE
If the vehicle is parked in direct sunlight under
high temperature conditions (over approxi-
mately 104°F [40°C]) and then started, the
LDW system may be deactivated automati-
cally and the following message will appear in
the vehicle information display: “Not avail-
able: High Camera Temp.”
When the interior temperature is reduced, the
LDW system will resume operating
automatically.
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
after the lane change signal is turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
5-38Starting and driving

•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
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 ProPILOT
Assist switch 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
deactivated automatically and the following
message will appear on the vehicle informa-
tion display: “Not available: High Camera
Temp.” When the interior temperature is re-
duced, the system will resume operating
automatically.
SYSTEM MALFUNCTION
If the LDP system malfunctions, it will cancel
automatically. The LDP indicator (orange)
will illuminate in the display. If the LDP indi-
cator (orange) illuminates in the display, pull
off the road to a safe location and stop the
vehicle. Turn the engine off and restart the
engine. If the LDP indicator (orange) contin-
ues to illuminate, have the LDP system
checked. It is recommended that you visit an
INFINITI retailer for this service.

BSI DRIVING SITUATIONS
Another vehicle approaching from
behind
Illustration 1: The side indicator light illumi-
nates if a vehicle enters the detection zone
from behind in an adjacent lane.
However, if the overtaking vehicle is traveling
much faster than your vehicle, the indicator
light may not illuminate before the detected
vehicle is beside your vehicle. 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.

Illustration 2: If the driver activates the turn
signal then the system chimes a sound (twice)
and the side indicator light flashes.
NOTE:
If the driver activates the turn signal before
a vehicle enters the detection zone, the side
indicator light will flash but no chime will
sound when the other vehicle is detected.Illustration 3: If the BSI system is on and your
vehicle is approaching a lane marker and a
vehicle is in the detection zone, the system
chimes a sound (three times), and the side
indicator light flashes. Then the BSI system
slightly applies the brakes on one side to help
return the vehicle back to the center of the
driving lane.
NOTE:
Illustration 4: If you accelerate from a stop
with a vehicle in the detection zone, the
other vehicle may not be detected.

nates if you overtake a vehicle and that ve-
hicle stays in the detection zone for approxi-
mately 3 seconds.
The radar sensors may not detect slower
moving vehicles if they are passed quickly.Illustration 6: If the driver activates the turn
signal while another vehicle is in the detection
zone, then the system chimes a sound (twice)
and the side indicator light flashes.
Illustration 7: If the BSI system is on and your
vehicle approaches a lane marker while an-
other vehicle is in the detection zone the sys-
tem chimes a sound (three times) and the side
indicator light flashes. Then, the BSI system
slightly applies the brakes on the appropriate
side to help return the vehicle back to the
center of the driving lane.

5-64Starting and driving

To reset at a slower cruising speed,use one
of the following three methods:
• Lightly tap the brake pedal. When the ve- hicle attains the desired speed, push the
SET– switch and release it.
• Push and hold the SET– switch. Release the switch when the vehicle slows to the de-
sired speed.
• Push and release the SET– switch. Each time you do this, the set speed decreases by
about 1 mph (1.6 km/h).
To resume the preset speed, push and re-
lease the RES+ switch. The vehicle returns to
the last set cruising speed when the vehicle
speed is over 25 mph (40 km/h).WARNING
Failure to follow the warnings and instruc-
tions for proper use of the ProPILOT Assist
system could result in serious injury or
death.
• ProPILOT Assist is not a self-driving
system. Within the limits of its capabili-
ties, as described in this manual, it helps
the driver with certain driving activities.
• The ProPILOT Assist system is not a re-
placement for proper driving procedures
and is not designed to correct careless,
inattentive or absent-minded driving.
ProPILOT Assist will not always steer
the vehicle to keep it in the lane. The Pro-
PILOT Assist system is not designed to
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.
• There are limitations to the ProPILOT
Assist system capability. The ProPILOT
Assist system does not function in all
driving, traffic, weather, and road condi-
tions. 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 ProPILOT Assist system is only an
aid to assist the driver and is not a colli-
sion warning or avoidance device.
• The ProPILOT Assist system is for high-
way use only and is not intended for city
driving. Failure to apply the brakes or
steer the vehicle when necessary may re-
sult in a serious accident.
• Always observe posted speed limits and
do not set the speed over them.
• Never take your hands off the steering
wheel when driving. Always keep your
hands on the steering wheel and drive
your vehicle safely.
• Never unfasten your safety belt when
using ProPILOT Assist. Doing so auto-
matically cancels the ProPILOT Assist
system.
• The ProPILOT Assist system does not
react to stationary and slow moving
vehicles.
