Infiniti QX56 (JA60). Manual — part 183
CCS-68
< SYMPTOM DIAGNOSIS >
NORMAL OPERATING CONDITION
• The sensor detection distance is limited if the vehicle-to-vehicle
distance is close. The vehicle distance may not maintain properly
because the motorcycle (A) driving on the lane edge is not
detected or detecting the vehicle ahead (cutting in the own vehicle)
delays.
• The sensor dirt is detected automatically. But it is not perfect. Dirt
is not judged despite the sensor is dirt. Dirt is not detected if snow
or ice is on the sensor.
Keeping the vehicle-to-vehicle distance is difficult. Drive the vehi-
cle safely. Always clean the sensor.
Intelligent Cruise Control is released automatically if dirt is
detected.
• The vehicle ahead may not be detected temporarily, the vehicle or object on the neighboring lane may be
detected or the warning buzzer may sound according to the road shape (curve and narrow road) and the
own vehicle condition (steering, driving lane position, accident, malfunction etc.).
The vehicle ahead is not detected temporarily. The vehicle approaches too close.
PRECAUTIONS FOR CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
• Conventional cruise control mode does neither control the brake nor activate the warning.
Drive the vehicle safely. Keep a safe distance between vehicles by decreasing the vehicle speed according
to the driving condition etc.
• Never use the conventional cruise control mode in the following conditions.
- A well-trafficed road, and a tight turn.
It may cause any accident because the driving does not fit to the road condition.
- A slippery road (e.g., freezing, or snowy road)
The vehicle may lose the control by wheelspin.
- A steep downhill
The engine brake does not activate effectively on a steep downhill. The preset vehicle speed may exceed.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005146018
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 SR and SB section of this Service Man-
ual.
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 SR section.
• 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.
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion 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.
ICC System Service
INFOID:0000000005146019
• Do not 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 dynamometer.
• Do not use the ICC sensor integrated unit removing from vehicle. Never disassemble and remodel.
• Erase DTC when replacing parts of ICC system, then check the operation of ICC system after adjusting laser
beam aiming if necessary.
