2019 INFINITI QX50 steering

∙ 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.”

1. Side indicator light
2. BSI/BSW/BCI/RCTA indicator light
3. Dynamic driver assistance switch (formodels without ProPILOTAssist)
4. ProPILOT Assist switch (for vehicles with ProPILOT Assist)
BSI SYSTEM OPERATION
The 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 an-
other vehicle comes into the detection
zone after your vehicle has crossed a lane
marker, no BSI warning or system appli-
cation will be activated. For additional
information, refer to “BSI driving situa-
tions” in this section.
∙ The BSI system is typically activated
earlier than the Lane Departure Preven-
tion (LDP) system when your vehicle is
approaching a lane marker.
The BSI system turns on when the dynamic
driver assistance switch (for models without
ProPILOT Assist) or the ProPILOT Assist
switch (for models with ProPILOT Assist) on
the steering wheel is pushed when the “Blind
Spot Intervention” is enabled in the “Driver
Assistance” menu in the lower display. The
BSI ON indicator light on the instrument
panel illuminates when the BSI system is
turned on. The BSI system provides a chime and turns on
or flashes the side indicator light even if the
BSW system is off.

SYSTEM TEMPORARILY
UNAVAILABLE
When any of the following messages appear
on the vehicle information display, a chime
will sound and the BSI system will be turned
off automatically.
∙ “Not Available Poor Road Conditions”: When the VDC system (except traction
control system function) or ABS oper-
ates.
∙ “Currently Not Available”: When the VDC system is turned off.
∙ “Not Available: High Camera Temp”: When the camera detects that the inte-
rior temperature is high (over approxi-
mately 104°F [40°C]). ∙ “Unavailable: Side Radar Obstruction”:
When side radar blockage is detected.
Turn off the BSI system and turn it on again
when the above conditions no longer exist.
SYSTEM MALFUNCTION
When the BSI system malfunctions, it will be
turned off automatically, a chime will sound
and the BSI system warning light (orange) will
illuminate.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off and restart the engine. If the warning
light (orange) continues to illuminate, have
the system checked. It is recommended that
you visit an INFINITI retailer for this service.
SYSTEM MAINTENANCE
The lane camera unit1for the BSI system is
located above the inside mirror. The two ra-
dar sensors
2for the BSI system are located
near the rear bumper. To keep the proper
operation of the BSI system and prevent a
system malfunction, be sure to observe the
following:
∙ Always keep the windshield and the area near the radar sensors clean.

5-64Starting and driving

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the speed
to maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway, the
ICC system will accelerate and maintain the
speed up to the set speed. Pay attention to
the driving operation to maintain control of
the vehicle as it accelerates to the set speed.
The vehicle may not maintain the set speed
on winding or hilly roads. If this occurs, you
will have to manually control the vehicle
speed.Normally when controlling the distance to a
vehicle ahead, this system automatically ac-
celerates or decelerates your vehicle accord-
ing to the speed of the vehicle ahead. De-
press the accelerator to properly accelerate
your vehicle when acceleration is required for
a lane change. Depress the brake pedal when
deceleration is required to maintain a safe
distance to the vehicle ahead due to its sud-
den braking or if a vehicle cuts in. Always stay
alert when using the ICC system.VEHICLE-TO-VEHICLE
DISTANCE CONTROL MODE
SWITCHES
The system is operated by the ICC switch and
four control switches, all mounted on the
steering wheel.
1. RES+ switch:
Resumes set speed or increases speed
incrementally.

Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the system
warns the driver with the chime and ICC sys-
tem display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are: ∙ When the vehicles are traveling at the same speed and the distance between
vehicles is not changing.
∙ When the vehicle ahead is traveling faster and the distance between vehicles
is increasing.
∙ When a vehicle cuts in near your vehicle. The warning chime will not sound when:
∙ The vehicle approaches other vehicles that are parked or moving slowly.
∙ The accelerator pedal is depressed, over- riding the system.
NOTE:
The approach warning chime may sound and
the system display may blink when the ICC
sensor detects objects on the side of the ve-
hicle or on the side of the road. This may
cause the ICC system to decelerate or accel-
erate the vehicle. The ICC sensor may detect
these objects when the vehicle is driven on
winding roads, narrow roads, hilly roads, or
when entering or exiting a curve. In these
cases you will have to manually control the
proper distance ahead of your vehicle.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driv-
ing position in the lane) or traffic or vehicle
condition (for example, if a vehicle is being
driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed: ∙ When the vehicle ahead is not detected and your vehicle is traveling below the
speed of 15 mph (24 km/h)
∙ When the system judges the vehicle is at a standstill
∙ When the shift lever is not in the D (Drive) position or Manual mode
∙ When the electronic parking brake sys- tem is applied
∙ When the VDC system is turned off
∙ When VDC operates
∙ When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor
∙ When a wheel slips
∙ When the radar signal is temporarily in- terrupted
Starting and driving5-95

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar sen-
sor may detect vehicles in a different lane, or
may temporarily not detect a vehicle traveling
ahead. This may cause the radar system to
decelerate or accelerate the vehicle.
The detection of vehicles may also be af-
fected by vehicle operation (steering maneu-
ver or traveling position in the lane, etc.) or
vehicle condition.If this occurs, the ICC system may warn you
by blinking the system indicator and sound-
ing the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.

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 sys-tem. Within the limits of its capabilities,
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.
∙ The ProPILOT Assist system does not re- act to stationary and slow moving
vehicles.
∙ Always drive carefully and attentively when using the ProPILOT Assist system.
Read and understand the Owner’s
Manual thoroughly before using the Pro-
PILOT Assist system. To avoid serious in-
jury or death, do not rely on the system to
prevent accidents or to control the vehi-
cle’s speed in emergency situations. Do
not use the ProPILOT Assist system ex-
cept in appropriate road and traffic
conditions. The ProPILOT Assist system is intended to
enhance the operation of the vehicle when
following a vehicle traveling in the same lane
and direction.
The ProPILOT Assist system uses a multi-
sensing front camera
Ainstalled behind the
windshield and a radar sensor located on the
front of the vehicle
Bto measure the dis-
tance to the vehicle ahead in the same lane
and to monitor the lane markers. If the vehicle
detects a slower moving vehicle ahead, the
system will reduce the vehicle speed so that
your vehicle follows the vehicle in front at the
selected distance. The system will also help
keep the vehicle centered in the traveling lane
when clear lane markings are detected.
