Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000010502282

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.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000010508842

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• Before removing and installing any control units, first turn the ignition power source and accessory

power source to the OFF, 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 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.

For vehicle with 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 operation pro-
cedure below before starting the repair operation.

OPERATION PROCEDURE

1.

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

2.

Open driver door.

3.

Turn the ignition switch to the ON position.
(At this time, the steering lock will be released.)

4.

Turn the ignition switch to OFF position with driver door open.

< PRECAUTION >

PRECAUTIONS

5.

Wait for 3 minutes or longer with driver door open.
NOTE:
• Do not close driver door because the steering wheel locks when driver door is closed.
• The auto acc function is adapted to this vehicle. For this reason, even when the ignition switch is turned

to OFF position, the accessory power source does not turned OFF and continues to be supplied for a
certain amount of time.

6.

Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.

7.

Perform the necessary repair operation.

8.

When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the ignition switch from OFF position to ON position, then to LOCK position. (The steering wheel will lock
when the ignition switch is turned to LOCK position.)

9.

Perform self-diagnosis check of all control units using CONSULT.

Service Notice or Precautions for Steering System

INFOID:0000000010502284

• In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehicle

condition, and then check wheel alignment.

• Observe the following precautions when disassembling.
- Before disassembly, thoroughly clean the outside of the unit.
- Disassembly should be done in a clean work area. It is important to prevent the internal parts from becoming

contaminated by dirt or other foreign matter.

- For easier and proper assembly, place disassembled parts in order on a parts rack.
- Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere with

their operation.

- Never reuse non-reusable parts.
- Before assembling, apply the specified grease to the directed parts.
• During quick steering, rasping noise may be heard from around the steering wheel. This is not a malfunction.

The noise is an operating noise of the EPS system under normal conditions. If the rasping noise occurs dur-
ing slow steering, this may not be an operating noise of the system. In this case, it is necessary to find out
the location of the noise and repair, if necessary.

• Never repeat static steering. (Motor and EPS control unit could be heated.)
