HOW TO ENABLE/DISABLE THE
LDW SYSTEM
Perform the following steps to enable or
disable the LDW system.
1. Push the MENU button
and touch
[Driver Assistance] on the lower display.
2. Touch [Lane Assist].
3. Touch [Lane Departure Warning] to enable or disable the system.
LDP SYSTEM OPERATION
The LDP system operates above approxi-
mately 45 MPH (70 km/h) and when the
lane markings are clear.
If the vehicle approaches either the left or
right side of the traveling lane, the driver
assist system lane indicator (orange) in the
vehicle information display will blink and a
warning chime will sound. Then, the LDP
system will automatically 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 direc-
tion of the signal. (The LDP system will
become operable again approximately 2
seconds after the lane change signal is
turned off.)
. The LDP will not operate or will stop
operating and only a warning chime will
sound under the following conditions.
— When the steering wheel is turned as
far as necessary for the vehicle to
change lanes.
— When the accelerator pedal is de-
pressed.
— When the Intelligent Cruise Control
(ICC), Distance Control Assist (DCA), Blind Spot Intervention (BSI), Blind
Spot Warning (BSW), Predictive For-
ward Collision Warning (PFCW) or
Forward Emergency Braking (FEB)
approach warning occurs.
— When the BSI system activates.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.
— When the brake pedal is depressed.
(models without Direct Adaptive
Steering)
. 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.

mPRECAUTIONS ON CRUISE
CONTROL
.If the cruise control system malfunctions,
it will cancel automatically. The cruise
indicator (green) in the vehicle informa-
tion display will then blink to warn the
driver.
. If the engine coolant temperature be-
comes excessively high, the cruise con-
trol system will be canceled
automatically.
. If the cruise indicator (green) blinks, turn
the cruise control MAIN switch off and
have the system checked. It is recom-
mended you visit an INFINITI retailer for
this service.
. The cruise indicator (green) may some-
times blink when the cruise control MAIN
switch is turned ON while pushing the
SET/COAST (-), RESUME/ACCELER-
ATE (+) or CANCEL switch. To properly
set the cruise control system, perform
the steps below in the order indicated.
WARNING
Do not use the cruise control when
driving under the following conditions:
. when it is not possible to keep the
vehicle at a set speed .
in heavy traffic or in traffic that
varies in speed
. on winding or hilly roads
. on slippery roads (rain, snow, ice,
etc.)
. in very windy areas
Doing so could cause a loss of vehicle
control and result in an accident.

Cruise indicator
The cruise indicator and the set vehicle
speed are displayed in the vehicle informa-
tion display. The cruise indicator indicates
the status of the cruise control system by the
color.
The cruise control allows driving at a speed
between 25 to 90 MPH (40 to 144 km/h)
without keeping your foot on the accelerator
pedal.
To turn on the cruise control, push the
MAIN switch on. The cruise indicator (white)
will come on.
To set cruising speed, accelerate your
vehicle to the desired speed, push the SET/
COAST (-) switch and release it. (The cruise
indicator (green) will illuminate.) Take your foot off the accelerator pedal. Your vehicle
will maintain the set speed.
.
To pass another vehicle, depress the
accelerator pedal. When you release the
pedal, the vehicle will return to the
previously set speed.
. The vehicle may not maintain the set
speed on winding or hilly roads. If this
happens, drive without the cruise con-
trol.
To cancel the preset speed, follow any of
these methods:
1. Push the CANCEL switch.
2. Tap the brake pedal.
3. Turn the MAIN switch off.
After any of the above operations is per-
formed, the color of the cruise indicator will
change from green to white.
. If you depress the brake pedal while
pushing the RESUME/ACCELERATE
(+) or SET/COAST (-) switch and reset
at the cruising speed, the cruise control
will disengage. Turn the MAIN switch off
once and then turn it on again.
. The cruise control will automatically
cancel if the vehicle slows more than 8
MPH (13 km/h) below the set speed.
. If you move the shift lever to N (Neutral)
position, the cruise control will be can-
celed.

To reset at a faster cruising speed,use one
of the following methods:
. Depress the accelerator pedal. When the
vehicle attains the desired speed, push
and release the SET/COAST (-) switch.
. Push and hold the RESUME/ACCELER-
ATE (+) switch. When the vehicle attains
the speed you desire, release the switch.
. Push, then quickly release the RESUME/
ACCELERATE (+) switch. Each time you
do this, the set speed will increase by
about 1 MPH (1.6 km/h).
To reset at a slower cruising speed, use one
of the following methods:
. Lightly tap the brake pedal. When the
vehicle attains the desired speed, push
the SET/COAST (-) switch and release it.
. Push and hold the SET/COAST (-)
switch. Release the switch when the
vehicle slows down to the desired speed.
. Push, then quickly release the SET/
COAST (-) switch. Each time you do this,
the set speed will decrease by about 1
MPH (1.6 km/h).
To resume the preset speed, push and
release the RESUME/ACCELERATE (+)
switch. The vehicle will resume the last set
cruising speed when the vehicle speed is over
25 MPH (40 km/h).
WARNING
Failure to follow the warnings and
instructions 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 it is 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 atten-
tively when using either cruise con-
trol mode. Read and understand the
Owner’s Manual 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 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 (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.
. Conventional (fixed speed) cruise control
mode:
For cruising at a preset speed.

VEHICLE-TO-VEHICLE DIS-
TANCE CONTROL MODE
In the vehicle-to-vehicle distance control
mode, the ICC system automatically main-
tains 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.

SSD0254
When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system 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 avehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is
required for a lane change. Depress the
brake pedal when deceleration 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.
