Infiniti FX35, FX50 (S51). Manual — part 340
CCS-180
< SYMPTOM DIAGNOSIS >
[ICC (FULL SPEED RANGE)]
NORMAL OPERATING CONDITION
• 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 vehi-
cle ahead. If the vehicle ahead changes lanes or exits the free-
way, 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, the driver will have to manually
control the vehicle speed.
• The sensor sensitivity can be affected by vehicle operation (steering maneuver or driving position in
the lane) or traffic or vehicle condition (for example, if a vehicle is being driven with some damage).
• Normally when controlling the distance to a vehicle ahead, this system automatically accelerates or
decelerates own vehicle according to the speed of the vehicle ahead. Depress the accelerator to
properly accelerate own 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 sud-
den braking or if a vehicle cuts in. Always stay alert when using the ICC system.
PRECAUTIONS FOR CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
CAUTION:
• In the conventional (fixed speed) cruise control mode, a warning chime does not sound to warn the
driver if own vehicle is too close to the vehicle ahead, as neither the presence of the vehicle ahead
nor the vehicle-to-vehicle distance is detected.
• Pay special attention to the distance between own vehicle and the vehicle ahead or a collision could
occur.
• Always confirm the setting in the ICC system display.
• Do not use the conventional (fixed speed) cruise control mode 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.
• To avoid accidentally engaging cruise control, make sure to the MAIN switch OFF when not using
ICC system.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005501760
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIR BAG”.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s)
with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly
causing serious injury.
• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Precautions For Harness Repair
INFOID:0000000005501761
ITS communication uses a twisted pair line. Be careful when repairing it.
• Solder the repaired area and wrap tape around the soldered area.
NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).

PRECAUTIONS
• Bypass connection is never allowed at the repaired area.
NOTE:
Bypass connection may cause ITS communication error. The
spliced wire becomes separated and the characteristics of twisted
line are lost.
ICC System Service
INFOID:0000000005501762
CAUTION:
• Never look straight into the laser beam discharger when adjusting laser beam aiming.
• Turn the MAIN switch OFF in conditions similar to driving, such as free rollers or a chassis dyna-
mometer.
• Never use the ICC sensor integrated unit removed from vehicle. Never disassemble or remodel.
• Erase DTC when replacing parts of ICC system, then check the operation of ICC system after adjust-
ing laser beam aiming if necessary.
