NORMAL OPERATING CONDITION
Description
INFOID:0000000010416942
PRECAUTIONS FOR LANE DEPARTURE WARNING (LDW)
CAUTION:
• The LDW system is only a warning device to inform the driver of a potential unintended lane depar-
ture. It will not steer the vehicle or prevent loss of control. It is the driver’s responsibility to stay
alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.
• The rear view camera may not detect properly under the following conditions:
- When towing a trailer.
- When strong light enters the rear view camera. (For example, direct sunlight or headlight from the
rear)
- When ambient brightness changes instantly. (For example, when the vehicle enters or exits a tunnel
or passes under a bridge.)
• Automatic washer and blower may not be able to secure detection capability when excessive dirt
adheres on the camera lens.
• LDW system may not function properly under the following conditions:
• Excessive noise (e.g. audio system volume, open vehicle window) will interfere with the chime
sound, and it may not be heard.
• The rear view camera may not be able to detect properly under the following conditions:
- 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 markers covered with
water, dirt, snow, etc.
- On roads where the discontinued lane markers are still detectable.
- On roads where there are sharply contrasting objects, such as shadows, snow, water, wheel ruts,
seams or lines remaining after road repairs. (The LDW system could detect these items as lane
markers.)
- On roads where the traveling lane merges or separates.
- When the vehicle
′
s traveling direction does not align with the lane marker.
- When the road surface is very dark due to scarce ambient light or impaired tail lamp.
• When driving on curved road, warning will be late on the outside of the curve due to the nature of the
system.
PRECAUTIONS FOR BLIND SPOT WARNING (BSW)
CAUTION:
• The BSW system is not a replacement for proper driving procedure and is not designed to prevent
contact with vehicles or objects. When changing lanes, always use the side and rear mirrors and
turn and look in the direction you will move to ensure it is safe to change lanes. Never rely solely on
the BSW system.
• The rear camera may not detect properly under the following conditions:
- When towing a trailer.
- When strong light enters the rear camera. (For example, direct sunlight or headlight from the rear)
- When ambient brightness changes instantly. (For example, when the vehicle enters or exits a tunnel
or passes under a bridge.)
• Automatic washer and blower may not be able to secure detection capability when excessive dirt
adheres on the camera lens.
• The camera unit may not be able to detect when certain objects are present such as:
- Pedestrians, bicycles, animals
- Several types of vehicles such as motorcycles
- Oncoming vehicles
- A vehicle approaching rapidly from behind.
- A vehicle which your vehicle overtakes rapidly.
• The rear camera may not be able to detect property when your vehicle travels beside the middle sec-
tion of a vehicle with long wheelbase(e.g. trailer truck, semi-trailer, tractor).
• The rear camera detection zone is designed based on a standard lane width. When driving in a wider
lane, the camera unit may not detect vehicles in an adjacent lane. When driving in a narrow lane, the
camera unit may detect vehicles driving two lanes away.
DAS-200
< SYMPTOM DIAGNOSIS >
[DRIVER ASSISTANCE SYSTEM]
NORMAL OPERATING CONDITION
• The rear camera is designed to ignore most stationary objects, however objects such as guardrails,
walls, foliage and parked vehicles may occasionally be detected. This is a normal operating condi-
tion.
• The rear camera may detect reflection image of vehicles or roadside objects that are not actually in
the detection zone, especially when the road is wet.
PRECAUTIONS FOR MOVING OBJECT DETECTION
CAUTION:
• The Moving Object Detection system is not a replacement for proper driving procedure and is not
designed to prevent contact with vehicles or objects. When backing up. always look in the direction
driver will move to ensure it is safe to proceed. Never rely solely on the Moving Object Detection
system.
• Using the Moving Object Detection system under some road or weather condition could lead to
improper system operation. Always rely on driver’s own steering and braking operation to avoid
accidents.
• The Moving Object Detection system may not provide a warning for vehicles that pass through the
detection zone quickly.
• Do not use the Moving Object Detection system when towing a trailer.
• Excessive noise (e.g., audio system volume, open vehicle window) will interfere with the chime
sound, and it may not be heard.
- Pedestrians, bicycles, animals.
- A vehicle passing at a speed greater than approximately 24km/h (15 MPH).
• A rear view camera may not detect approaching vehicles in certain situations:
- When the vehicle parked aside obstruct the beam of the rear view camera.
- When the vehicle is parked in an angled parking space.
- When the vehicle is parked on an inclined ground.
- When the vehicle turns around into your vehicle’s aisle.
- When the angle formed by your vehicle and approaching vehicle is small.
• Severe weather or road spray conditions may reduce the ability of the radar to detect other vehicles.
• The rear view camera system may not detect:
- Small or moving object.
- Wedge-shaped objects.
- Object closer to the bumper than 30 cm (10 inch).
- Thin objects such as rope, wire, chain, etc.
• Do not use the MOD system under the following conditions because the system may not function
properly:
- When driving with a tire that is not the within normal tire condition (example: tire wear, low pressure,
spare tire, chain, non-standard wheels).
- When the vehicle is equipped with non-original brake parts or suspension parts.
PRECAUTIONS FOR DRIVER ATTENTION ALERT
CAUTION:
This is not a system to assist driving while tired. Driving while tired may lead to a serious accident. Be
sure to have sufficient rest before driving, and drive safely.
PRECAUTIONS FOR TRAFFIC SIGN RECOGNITION
CAUTION:
• There are limitations to the do not enter sign detection function. Be careful to observe traffic signs,
etc. and drive safely.
• Detection may not be possible depending on the vehicle status, driving conditions, traffic environ-
ment, weather conditions, and the condition of the sign.
• Under conditions such as the following, detection of do not enter sign is delayed and detection may
not be possible.
- A portion of the sign is hidden and obscured by a tree, dirt, etc.
- The shape of the sign is changed due to the sign being bent, etc.
- The do not enter sign is around a corner or on a curve.
- The vehicle is traveling at a fast speed.
• Depending on certain conditions, it may not be possible to hear the warning sound due to outside
noises.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010417375
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. Information necessary to service the system safely is included in the “SRS AIR BAG” and
“SEAT BELT” of this Service Manual.
WARNING:
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that 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 “SRS AIR BAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never 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 Removing Battery Terminal
INFOID:0000000010519320
• With the adoption of Auto ACC function, ACC power is automatically supplied by operating the intelligent key
or remote keyless entry or by opening/closing the driver side door. In addition, ACC power is supplied even
after the ignition switch is turned to the OFF position, i.e. ACC power is supplied for a certain fixed time.
• When disconnecting the 12V battery terminal, turn off the ACC
power before disconnecting the 12V battery terminal, observing
“How to disconnect 12V battery terminal” described below.
NOTE:
Some ECUs operate for a certain fixed time even after ignition
switch is turned OFF and ignition power supply is stopped. If the
battery terminal is disconnected before ECU stops, accidental DTC
detection or ECU data damage may occur.
• For vehicles with the 2-batteries, be sure to connect the main bat-
tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
NOTE:
The removal of 12V battery may cause a DTC detection error.
HOW TO DISCONNECT 12V BATTERY TERMINAL
Disconnect 12V battery terminal according to Instruction 1 or Instruction 2 described below.
For vehicles parked by ignition switch OFF, refer to Instruction 2.
INSTRUCTION 1
1.
Open the hood.
