steering wheel INFINITI QX50 2021 Service 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 vehicle
or prevent loss of control. It is the driv-
er’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
O1
located above the inside mirror.

LDP SYSTEM OPERATION
1. LDP indicator
2. Lower display buttons3. LDP ON indicator
4. ProPILOT Assist switchThe 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.

WARNING
Listed below are the system limitations for
the LDP system. Failure to follow the
warnings and instructions for proper use of
the LDP system could result in serious in-
jury or death.

5-42Starting 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.

4ProPILOT Assist switch
The ProPILOT Assist system has the follow-
ing two functions:
1. Intelligent Cruise Control (ICC)
The ICC system can be set to one of two
cruise control modes:
• Conventional (fixed speed) cruise control
mode: For cruising at a preset speed
NOTE:Steering assist is not available in the conven-
tional (fixed speed) cruise control mode.
•Vehicle-to-vehicle distance control mode:
The ICC system maintains a selected dis-
tance from the vehicle in front of you within
the speed range of 0 to 90 mph (0 to 144
km/h) up to the set speed. The set speed
can be selected by the driver between 20 to
90 mph (30 to 144 km/h). When the ve-
hicle ahead slows to a stop, your vehicle
gradually decelerates to a standstill. When
the vehicle is stopped, the ICC system
maintains braking force to keep your ve-
hicle stopped.
NOTE:When your vehicle is stopped for less than 3
seconds and the vehicle ahead begins to
move, your vehicle will start moving again
automatically.
