LANE CAMERA UNIT MAINTENANCE
The lane camera unit*1for the LDW/LDP
system is located above the inside mirror.
To keep the proper operation of the LDW/
LDP systems and prevent a system mal-
function, be sure to observe the following:
. Always keep the windshield clean.
. Do not attach a sticker (including
transparent 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 adversely affect the cam- era 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, contact an INFINITI retailer.
PRECAUTIONS ON CRUISE CONTROL
. If the cruise control system malfunc-
tions, it will cancel automatically. The
SET indicator on the dot matrix crystal
display will then blink to warn the
driver.
. If the engine coolant temperature be-
comes excessively high, the cruise
control system will be canceled auto-
matically.
. If the SET indicator blinks, turn the
cruise control main switch off and have
the system checked by your INFINITI
retailer.
. The SET indicator may sometimes blink
when the cruise control main switch is
turned ON while pushing the ACCELER-
ATE/RESUME, COAST/SET or CANCEL
switch. To properly set the cruise
control system, perform the steps
below in the order indicated.

CRUISE CONTROL OPERATIONS
The cruise control allows driving at a speed
between 25 to 89 MPH (40 to 144 km/h)
without keeping your foot on the accel-
erator pedal.
To turn on the cruise control, push the
MAIN switch on. The CRUISE indicator will
come on.
To set cruising speed, accelerate your
vehicle to the desired speed, push the COAST/SET switch and release it. (The
CRUISE SET indicator will come on in the
instrument panel.) Take your foot off the
accelerator pedal. Your vehicle will main-
tain 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 button. The SET indicator will go out.
2. Tap the brake pedal. The SET indicator will go out.
3. Move the selector lever to the N (Neutral) position. The SET indicator
will go out.
4. Turn the MAIN switch off. Both the CRUISE indicator and SET indicator will
go out.
. If you depress the brake pedal while
pushing the ACCELERATE/RESUME or
COAST/SET 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 selector lever to the N
(Neutral) position, the cruise control
will be canceled.
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 COAST/SET
switch.
. Push and hold the ACCELERATE/RE-
SUME switch. When the vehicle attains
the speed you desire, release the
switch.
. Push, then quickly release the ACCEL-
ERATE/RESUME 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 COAST/SET switch and release it. .
Push and hold the COAST/SET switch.
Release the switch when the vehicle
slows down to the desired speed.
. Push, then quickly release the COAST/
SET 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 ACCELERATE/RESUME switch.
The vehicle will resume the last set
cruising speed when the vehicle speed is
over 25 MPH (40 km/h). 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.
. Conventional (fixed speed) cruise con-
trol mode:
For cruising at a preset speed.
WARNING
. 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

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.
With ICC, the driver can maintain the same
speed as other vehicles without the con-
stant need to adjust the set speed as you
would with a normal cruise control system.
SSD0738
PRECAUTIONS ON VEHICLE-TO-VE-
HICLE DISTANCE CONTROL MODE
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
*Adetects 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
25% of vehicle braking power) if neces- sary.
The detection range of the sensor is
approximately 390 ft (120 m) ahead.
WARNING
.
This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’ s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. The system is primarily intended for use
on straight, dry, open roads with light
traffic. It is not advisable to use the
system in city traffic or congested areas.
. This system will not adapt automatically
to road conditions. This system should
be used in evenly flowing traffic. Do not
use the system on roads with sharp
curves, or on icy roads, in heavy rain or
in fog.
The distance sensor will not detect the
following objects:
.Stationary and slow moving vehicles
. Pedestrians or objects in the roadway
Starting and driving5-33

5-34Starting and driving
.Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain a
safe distance between vehicles.
. If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
. The system may not detect the vehicle in
front of you in certain road or weather conditions. To avoid accidents, never use
the Intelligent Cruise Control system
under the following conditions:
—On roads where the traffic is heavy
or there are sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—During bad weather (rain, fog, snow,etc.)
When the windshield wiper is oper-
ated at the low speed (LO) or high
speed (HI) position, the Intelligent
Cruise Control system is automati-
cally canceled.
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere to
the system sensor
—On steep downhill roads (the vehi-cle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
—On repeated uphill and downhillroads
—When traffic conditions make itdifficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
. Do not use the Intelligent Cruise Control
system if you are towing a trailer. The
system may not detect a vehicle ahead.
. In some road or traffic conditions, a
vehicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to
control the distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the ICC system
when it is not recommended in this
section.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance. The
vehicle-to-vehicle distance control mode of
the Intelligent Cruise Control (ICC) system
may not be able to maintain the selected
distance between vehicles (following dis-
tance) or selected vehicle speed under
some circumstances.
The vehicle-to-vehicle distance control
mode uses a sensor
*Alocated on the
front of the vehicle to detect vehicles traveling ahead. The sensor generally
detects the signals returned from the
reflectors on a vehicle ahead. Therefore, if
the sensor cannot detect the reflector on
the vehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which
the sensor cannot detect the signals:
.
When the reflector of the vehicle ahead
is positioned high on the vehicle
(trailer, etc.)
. When the reflector on the vehicle ahead
is missing, damaged or covered
. When the reflector of the vehicle ahead
is covered with dirt, snow and road
spray
. When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When dense exhaust or other smoke
(black smoke) from vehicles reduces
the sensor’s visibility
. When excessively heavy baggage is
loaded in the rear seat or the luggage
room of your vehicle
The ICC system is designed to automati-
cally check the sensor’s operation within
the limitation of the system. When the sensor is covered with dirt or is obstructed,
the system will automatically be canceled.
If the sensor is covered with ice, a
transparent or translucent vinyl bag, etc.,
the ICC system may not detect them. In
these instances, the vehicle-to-vehicle dis-
tance control mode may not cancel and
may not be able to maintain the selected
following distance from the vehicle ahead.
Be sure to check and clean the sensor
regularly.
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
25% of the vehicles 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-
