2021 INFINITI QX50 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.

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.
To turn on the LDP system, push the ProPI-
LOT Assist switch on the steering wheel af-
ter starting the engine. The LDP ON indicator

LDP SYSTEM LIMITATIONS
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.
LSD3935
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.

BLIND SPOT WARNING (BSW)
Starting and driving5-45

The BSW system uses radar sensorsO1in-
stalled near the rear bumper to detect other
vehicles in an adjacent lane. The radar sensors can detect vehicles on ei-
ther side of your vehicle within the detection
zone shown as illustrated. This detection
zone starts from the outside mirror of your
vehicle and extends approximately 10 ft (3.0
m) behind the rear bumper, and approxi-
mately 10 ft (3.0 m) sideways.
