LDP SYSTEM OPERATION

The LDP system operates above approxi-
mately 45 MPH (70km/h) and when the
lane markings are clear.
If the vehicle approaches either the left or
right side of the traveling lane, the LDW
indicator light (orange) on the instrument
panel will flash and a warning chime will
sound. Then, the LDP system will auto-
matically apply the brakes for a short
period of time to help assist the driver to
return the vehicle to the center of the
traveling lane.

NOTE:
.

The LDP system is not designed to work

when you operate the lane change
signal and change traveling lanes in
the direction of the signal. (The LDP
system will become operable again
approximately 2 seconds after the lane
change signal is turned off.)

.

The LDP braking assist will not operate

or will stop operating and only a
warning chime will sound under the
following conditions.
— When the brake pedal is depressed.
— When the steering wheel is turned

as far as necessary for the vehicle to

change lanes.

— When the accelerator pedal is de-

pressed while brake control assist
is provided.

— When the Intelligent Cruise Control

(ICC), Forward Collision Warning
(FCW) or Intelligent Brake Assist
(IBA) warnings sound.

— When the hazard warning flashers

are operated.

— When driving on a curve at a high

speed.

.

While the LDP system is operating, you

may hear a sound of brake operation.
This is normal and indicates that the
LDP system is operating properly.

LDW/LDP SYSTEM LIMITATIONS

WARNING

Listed below are the system limitations for
the LDW and LDP systems. Failure to operate
the vehicle in accordance with these system
limitations could result in serious injury or
death.

.

The system will not operate at speeds
below 45 MPH (70 km/h) or if it cannot
detect lane markers.

.

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.

Condition:

(365,1)

Model: 2017MY INFINITI QX70(S51) OM17E00S51U0 ]

.

Do not use the LDP system under the
following conditions as it may not
function properly:

— During bad weather (rain, fog, snow,

etc.).

— When driving on slippery roads,

such as on ice or snow, etc.

— When driving on winding or uneven

roads.

— When there is a lane closure due to

road repairs.

— When driving in a makeshift or

temporary 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

non-original brake parts or suspen-
sion parts.

— When you are towing a trailer or

other vehicle.

.

The camera may not detect lane markers
in the following situations and the LDW
and LDP systems may not operate
properly.

— On roads where there are multiple

parallel lane markers, lane markers
that are faded or not painted clearly,
yellow painted lane markers, non-
standard lane markers, or lane mar-
kers covered with water, dirt, snow,
etc.

— On roads where the discontinued

lane markers are still detectable.

— On roads where there are sharp

curves.

— On roads where there are sharply

contrasting objects, such as sha-
dows, snow, water, wheel ruts,
seams or lines remaining after road
repairs. (The LDW and LDP systems
could detect these items as lane
markers.)

— On roads where the traveling lane

merges or separates.

— When the vehicle’s traveling direc-

tion 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

camera unit. (For example, the light
directly shines on the front of the
vehicle at sunrise or sunset.)

— When a sudden change in bright-

ness occurs. (For example, when the
vehicle enters or exits a tunnel or
under a bridge.)

.

Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.

WARNING

Failure to follow the warnings and instruc-
tions for proper use of the ICC system could
result in serious injury or death.

.

ICC is not a collision avoidance or
warning device. For highway use only
and not intended for congested areas or
city driving. Failure to apply the brakes
could result in an accident.

.

Always observe posted speed limits and
do not set the speed over them.

.

Always drive carefully and attentively
when using either cruise control mode.
Read and understand the Owner’s Man-
ual thoroughly before using the cruise
control. To avoid serious injury or death,
do not rely on the system to prevent
accidents or to control the vehicle’s
speed in emergency situations. Do not
use cruise control except in appropriate
road and traffic conditions.

.

In the conventional (fixed speed) cruise
control mode, a warning chime will not
sound to warn you if you are too close to
the vehicle ahead. Pay special attention
to the distance between your vehicle and
the vehicle ahead of you or a collision

could occur.

The Intelligent Cruise Control (ICC) system
maintains a selected distance 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 (32 to 144 km/h).
The vehicle travels at a set speed when the
road ahead is clear.
The ICC system can be set to one of two
cruise control modes.

.

Vehicle-to-vehicle distance control

mode:
For maintaining a selected distance
between your vehicle and the vehicle
in front of you up to the preset speed.

.

VEHICLE-TO-VEHICLE DISTANCE

CONTROL MODE

In the vehicle-to-vehicle distance control
mode, the Intelligent Cruise Control (ICC)
system automatically maintains a selected
distance from the vehicle traveling in front
of you according to that vehicle’s speed (up
to the set speed), or at the set speed when
the road ahead is clear.

JVS0124X

The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the distance sensor

*

A

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 automatically controls the
throttle and applies the brakes (up to
40% of vehicle braking power) if neces-
sary.
The detection range of the sensor is
approximately 390 ft (120 m) ahead.

Condition:

(373,1)

Model: 2017MY INFINITI QX70(S51) OM17E00S51U0 ]

Vehicle-to-vehicle distance control

mode operation

The vehicle-to-vehicle distance control
mode is designed to maintain a selected
distance and reduce the speed to match
the slower vehicle ahead. The system will
decelerate the vehicle as necessary and if
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill. How-
ever, the ICC system can only apply up to
40% of the vehicle’s total braking power.
This system should only be used when
traffic conditions allow vehicle speeds to
remain fairly constant or when vehicle
speeds change gradually. If a vehicle
moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decele-
rates, the distance between vehicles may
become closer because the ICC system
cannot decelerate the vehicle quickly en-
ough. If this occurs, the ICC system will
sound a warning chime and blink the
system display to notify the driver to take
necessary action.
The system will cancel and a warning
chime will sound if the speed is below
approximately 15 MPH (24 km/h) and a
vehicle is not detected ahead. The system
will also disengage when the vehicle goes

above the maximum set speed.
See “Approach warning” (P.5-43).
The following items are controlled in the
vehicle-to-vehicle distance control mode:
.

When there are no vehicles traveling

ahead, the vehicle-to-vehicle distance
control mode maintains the speed set
by the driver. The set speed range is
between approximately 20 and 90 MPH
(32 and 144 km/h).

.

When there is a vehicle traveling ahead,

the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by driver, from the
vehicle ahead. The adjusting speed
range is up to the set speed. If the
vehicle ahead comes to a stop, the
vehicle decelerates to a standstill with-
in the limitations of the system. The
system will cancel once it judges a
standstill with a warning chime.

.

When the vehicle traveling ahead has

moved out from its lane of travel, the
vehicle-to-vehicle distance control
mode accelerates and maintains vehi-
cle speed up to the set speed.

The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow moving vehicles. You

must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead when approaching toll gates or
traffic congestion.

Starting and driving

SSD0254

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC 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
accelerates or decelerates your vehicle
according to the speed of the vehicle
ahead. Depress the accelerator pedal to
properly accelerate your vehicle when
acceleration is required for a lane change.
Depress the brake pedal when decelera-
tion is required to maintain a safe distance
to the vehicle ahead due to its sudden
braking or if a vehicle cuts in. Always stay
alert when using the ICC system.
