2020 INFINITI QX50 lane assist

When the dynamic driver assistance switch is
turned off, the indicator on the switch is off.
The indicator will also be off if the system is
deactivated using the settings menu.
The DCA system brakes and moves the ac-
celerator pedal upward according to the dis-
tance from and the relative speed of the ve-
hicle ahead to help assist the driver in
maintaining a following distance. For addi-
tional information, refer to “Distance Control
Assist (DCA)” in the “Starting and driving”
section of this manual.
The BSI system helps alert the driver of other
vehicles in adjacent lanes when changing
lanes, and helps assist the driver to return the
vehicles to the center of the traveling lane.
For additional information, refer to “Blind
Spot Intervention® (BSI)” in the “Starting and
driving” section of this manual.
The LDP system warns the driver with a
warning indicator in the vehicle information
display and a steering wheel vibration, 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). For additional
information, refer to “Lane Departure Pre-
vention (LDP)” in the “Starting and driving”
section of this manualThe Steering Assist switch is used to turn on
and off the Steering Assist system that is
activated using the settings menu of the ve-
hicle information display.
The Steering Assist system controls the
steering system to help keep your vehicle
near the center of the lane when driving. For
additional information, refer to “ProPILOT
Assist” in the “Starting and driving” section of
this manual.
WARNING
∙ The front sonar system is a convenience
but it is not a substitute for proper
driving.
∙ The rear sonar system is a convenience but it is not a substitute for proper back-
ing. Always turn and check that it is safe
to do so before backing up. Always back
up slowly.

LDW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the LDW system. Failure to follow the
warnings and instructions for proper use of
the LDW system could result in serious in-
jury or death.
∙ This system is only a warning device toinform the driver of a potential unin-
tended lane departure. It will not steer
the vehicle or prevent loss of control. It is
the driver’s responsibility to stay alert,
drive safely, keep the vehicle in the trav-
eling lane, and be in control of the vehicle
at all times.

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.

HOW TO ENABLE/DISABLE THE
LDP SYSTEM
When the LDP system is enabled in the lower
display, the system can be turned off tempo-
rarily by pushing the dynamic driver assis-
tance switch (for vehicles without ProPILOT
Assist) or the ProPILOT Assist switch (for
vehicles with ProPILOT Assist) on the steer-
ing wheel.
Perform the following steps to enable or dis-
able the LDP system.1. Press the MENU button below the lower display screen.
2. Select “Driver Assistance.”
3. Select “Lane Assist.”
4. Select “ON” to turn the “Lane Departure Prevention” system on or off.
NOTE:
Turning on the ProPILOT Assist system (if so
equipped) will turn on the LDP system at the
same time. For additional information, refer
to “ProPILOT Assist” in this section.

5-42Starting and driving

∙ 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.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the BSI system could
result in serious injury or death.
∙ The BSI system is not a replacement for
proper driving procedure 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 you will move to en-
sure it is safe to change lanes. Never rely
solely on the BSI system.
∙ There is a limitation to the detection ca- pability of the radar or the sonar. Not
every moving object or vehicle will be de-
tected. Using the BSI system under some
road, ground, lane marker, traffic or
weather conditions could lead to im-
proper system operation. Always rely on
your own operation to avoid accidents.
The BSI system helps alert the driver of other
vehicles in adjacent lanes when changing
lanes and helps assist the driver to return the
vehicle to the center of the traveling lane.
