Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005875003
The Supplemental Restraint System such as “A IR 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 w hether 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 inopera tive, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses 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 Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005875004
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK ″ position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:

INSPECTION AND ADJUSTMENT
NOTE:
If the adjustment screen does not appear on CONSULT-III 10 sec. after touching “LASER BEAM ADJUST”
screen, the following causes may be considered:
• Target is not set accurately.
• There is not enough space beside the target.
• Deformation of vehicle or inappropriate installation of sensor. Sensor may be installed out of the adjustablerange.
• The area is not suitable for the adjustment work.
• ICC sensor is not clean.
>> GO TO 2
2.LASER BEAM AIMING CONFIRMATION
After the CONSULT-III displays “ADJ UST THE VERTICAL OF LASER BEAM AIMING” turn the vertical adjust-
ing screw until “U/D CORRECT” value is set in the range of ±4.
NOTE:
• Turn the screw slowly. The value on the CONSULT-III is slower
than the actual movement of the ICC sensor. Wait 2 seconds
between each adjustment. Also, during adjustment work, do not
block the ICC sensor lens with your hand or body. In that case,
there are times when aiming cannot be conducted correctly.
• Turning the screw clockwise raises the ICC sensor and counter- clockwise lowers the ICC sensor.
>> GO TO 3
3.LASER BEAM AIMING CONFIRMATION
1. When “U/D CORRECT” value indicates ±4, confirm that the value remains within ±4 for at least 2 seconds
while nothing is touching the ICC sensor.
2. When “COMPLETED THE VERTICAL AIMING OF LASER BEAM” appears on screen, touch “END”.
NOTE:
Be sure that the margin of “U/D CORRECT” is within ±4 when the ICC sensor unit is untouched.
3. Confirm that “ADJUSTING AUTOMATIC HORIZONTAL LASER BEAM AIMING” is on screen and wait
while the horizontal adjustment is made automatically. (maximum: 10 seconds).
4. Confirm that “NORMALLY COMPLETED” is displayed on CONSULT-III and close the aiming adjustment procedure by touching “END”.
NOTE:
Complete all the procedures once “LASER BEAM AD JUST” mode is entered in CONSULT-III. When the
procedure is discontinued, the ICC system is inoperable.
>> LASER BEAM AIMING ADJUSTMENT END.
CHECK AFTER THE ADJUSTMENT

PRECAUTIONS FOR VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
• Intelligent Cruise Control is functionally limited. This never support careless driving and low visibility (rain,fog, etc.). Drive the vehicle safely. Keep a safe di stance between vehicles by decreasing the vehicle speed
according to the driving condition etc.
• Intelligent Cruise Control never stop the vehicle autom atically. Intelligent Cruise Control is automatically
released, and the buzzer sounds if any vehicle ahead is not detected when the vehicle speed is approxi-
mately 35 km (21.5 MPH) or less.
• Use this system when the vehicle speed does not extr emely change. This system may not properly function
when any vehicle cuts in, or when the vehicle ahead s uddenly applies the brake. Then, the warning (buzzer
and indication) activates.
• Never use Intelligent Cruise Control in the following conditions.
- A well-trafficed road, and a tight turn. It may cause any accident because the dr iving does not fit to the road condition.
- A slippery road (e.g., freezing, or snowy road) The vehicle may lose the control by wheelspin.
- The vehicle drives in bad whet her (rain, fog, snow etc.).
The distance from the vehicle ahead is not detected pr ecisely if the whether condition is bad. Intelligent
Cruise Control is released automatically if the wiper activates in low or high speed.
- The vehicle receives bright light (sunshine etc.). The distance from the vehicle ahead is not detected pr ecisely if bright light enters in the vehicle.
- Raindrop or snow is on the sensor.
The distance from the vehicle ahead is not detected prec isely if raindrop or snow attaches on the sensor.
- A steep downhill The setting vehicle speed may exceed if Intelligent Cruise Control does not detect the vehicle ahead. The
brake may heat up in the vehicle- to-vehicle distance control mode.
- A repeated uphill and downhill Intelligent Cruise Control may not detect the vehicl e ahead precisely. An accident may occur by tailgating.
- Maintaining proper vehicle distance is difficult due to frequent acceleration/deceleration. It may cause any accident because the driving does not fit to the road condition if keeping a proper vehicle-
to-vehicle distance is difficult.
- When entering in the highway interchange (swerving off the main line),
Unexpected accident may cause if the vehicle ahead drives slower
than the preset vehicle speed. T he vehicle-to-vehicle distance con-
trol mode accelerates automatically because the vehicle ahead is
not detected on the lane if the own vehicle or the vehicle ahead
changes the lane.
• Intelligent Cruise Control does not activate to the parking vehicles, and vehicles driving extremely slow er than the own vehicle. Never
hit the vehicle stopping at a tollgate, or the tail end of traffic jam.
• Intelligent Cruise Control does not activate to the vehicle edging way, and non-vehicle objects (passengers etc.).
• This function detects the reflector of the vehicle ahead. Intelligent Cruise Control may not detect the vehicle
ahead, and keep a proper vehicle-to-vehicle distance in t he following conditions. Drive the vehicle according
to the driving condition.
- The vehicle ahead installs the reflector higher (trailer etc.).
- The rear of the vehicle ahead is extremely dirt.
- The vehicle ahead or vehicle on other lanes splashes water or snow on the road.
- The vehicle ahead provides dark exhaust gas. Smoke blocks the visibility.
- The vehicle ahead attaches film on the reflector. The v ehicle ahead does not install the reflector. The reflec-
tor is broken.
- Extremely heavy load is on the rear seat or in the cargo area.
- The vehicle drives on a repeated uphill and downhill

charging/discharging current of the battery and performs various engine controls. If an electrical com-
ponent is connected directly to the negative battery terminal, the current flowing through that compo-
nent will not be measured by the battery current sensor. This condition may cause a malfunction of
the engine control system and battery discharge m ay occur. Do not connect an electrical component
or ground wire directly to the battery terminal.
