LANE DEPARTURE PREVENTION
(LDP) SYSTEM
Precautions on LDP system
WARNING
.The LDP system 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 traveling
lane, and be in control of 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 roads, weather or driving
conditions.
. Using the LDP system under some
conditions of road, lane marker or
weather, or when you change lanes
without using the lane change signal
could lead to an unexpected system
operation. In such conditions, you need
to correct the vehicle’s direction with
your steering operation to avoid acci-
dents. .
When the LDP system is operating, avoid
excessive or sudden steering maneu-
vers. Otherwise, you could lose control
of the vehicle.
. The LDP system will not operate at
speeds below approximately 45 MPH
(70 km/h) or if it cannot detect lane
markers.
. The LDP system may not function
properly under the following conditions,
and do not use the LDP system:
—During bad weather (rain, fog, snow,
wind, etc.).
—When driving on slippery roads,
such as on ice or snow, etc.
—When driving off-road such as on sand or rock, etc.
—When driving on winding or uneven
roads.
—When there is a lane closure due toroad repairs.
—When driving in a makeshift lane.
—When driving on roads where thelane width is too narrow.
—When driving without normal tireconditions (for example, tire wear, low tire pressure, installation of
spare tire, tire chains, non-standard
wheels).
—When the vehicle is equipped with
non-original brake parts or suspen-
sion parts.
—When towing a trailer or othervehicle.
. If the LDP system malfunctions, it will
cancel automatically. The lane departure
warning light (orange) on the instrument
panel will illuminate.
. If the lane departure warning light
(orange) illuminates, pull off the road
to a safe location and stop the vehicle.
Turn the engine off and restart the
engine. If the warning light (orange)
continues to illuminate, have the LDP
system checked by an INFINITI retailer.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
The functions of the LDP system (warning
and brake control assist) may or may not
operate properly under the following con-
ditions:

PREVIEW FUNCTION (for Intelligent
Cruise Control (ICC) system
equipped model)
The Intelligent Cruise Control (ICC) system
with the preview function identifies the
need to apply emergency braking by
sensing the vehicle ahead in the same
lane and the distance to the vehicle ahead
and relative speed from it, it applies the
brake pre-pressure before the driver de-
presses the brake pedal and helps improve
brake response by reducing pedal free
play.

provide unnecessary warning.
. The system may not function in offset
conditions.
. The system may not function when the
distance to the vehicle ahead is extre-
mely close.
. The system is designed to automatically
check the sensor’s functionality. If the
sensor is covered with ice, a transparent
or translucent plastic bag, etc., the
system may not detect them. In these
instances the system may not be able to
warn the driver properly. Be sure to
check and clean the sensor regularly.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
. A sudden appearance of a vehicle in
front (for example, it abruptly cuts in)
may not be detected and the system may
not warn the driver soon enough.
. The system will be cancelled automati-
cally with a beep sound and the IBA OFF
indicator light will illuminate under the
following conditions:
—When the sensor window is dirty
