Precautions for Removing Battery Terminal
INFOID:0000000012959273
When disconnecting the battery terminal, pay attention to the following.
• Always use a 12V battery as power source.
• Never disconnect battery terminal while engine is running.
• When removing the 12V battery terminal, turn OFF the ignition
switch and wait at least 30 seconds.
• For vehicles with the engine listed below, remove the battery termi-
nal after a lapse of the specified time:
NOTE:
ECU may be active for several tens of seconds after the ignition switch is turned OFF. If the battery terminal
is removed before ECU stops, then a DTC detection error or ECU data corruption may occur.
• After high-load driving, if the vehicle is equipped with the V9X engine, turn the ignition switch OFF and wait
for at least 15 minutes to remove the battery terminal.
NOTE:
• Turbocharger cooling pump may operate in a few minutes after the ignition switch is turned OFF.
• Example of high-load driving
- Driving for 30 minutes or more at 140 km/h (86 MPH) or more.
- Driving for 30 minutes or more on a steep slope.
• For vehicles with the 2-batteries, be sure to connect the main battery 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 discon-
nected, 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.
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012197542
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:
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, it is recommended that all maintenance
and repair be performed by an authorized NISSAN/INFINITI dealer.
• Improper repair, 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”.

PRECAUTIONS
• 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 or batteries, and wait at least 3 minutes before performing any service.
Precautions Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000012197544
NOTE:
• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
• Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-II.

Multi-way Control Valve
INFOID:0000000012197549
A motor-driven valve that integrates the thermostat and water control
valve and that can open and close the flow of water to the heater, oil
cooler, and radiator according to the coolant temperature is adopted.
• When the water temperature is low, the water channels to the
heater, oil cooler, and radiator are closed, accelerating warming of these parts.
• After they are warmed up, the radiator water channel is opened and closed to control the hot water tempera-
ture (100 to 105
°
C), raising the engine oil temperature for reducing friction and improving fuel economy.
For control, refer to
