PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000010305429
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:
• 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 “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:
• 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:0000000010305430
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 switch in the
″
LOCK
″
position.
• Always use CONSULT 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 power is interrupted, 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.
Use the Intelligent Key or mechanical key to turn the ignition switch to the
″
ACC
″
position. At this time, the
steering lock will be released.
3.
Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4.
Perform the necessary repair operation.
5.
When the repair work is completed, return the ignition switch to the
″
LOCK
″
position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6.
Perform a self-diagnosis check of all control units using CONSULT.

PRECAUTIONS
Precaution for Procedure without Cowl Top Cover
INFOID:0000000010305431
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake System
INFOID:0000000010305432
WARNING:
Clean any dust from the front brake and rear brake with a vacuum dust collector. Never blow with com-
pressed air.
CAUTION:
• Only use “DOT 4” brake fluid. Refer to
MA-59, "Fluids and Lubricants"
.
• Never reuse drained brake fluid.
• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it
off immediately and wash with water if it gets on a painted surface.
• Always clean with new brake fluid when cleaning the master cylinder, brake caliper and other com-
ponents.
• Never use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and
cause improper operation.
• Always loosen the brake tube flare nut with a flare nut wrench.
• Tighten the brake tube flare nut to the specified torque with
flare nut torque wrench (A).
• Always confirm the specified tightening torque when install-
ing the brake pipes.
• Turn the ignition switch OFF and disconnect the ABS actuator
and electric unit (control unit) connector or the battery nega-
tive terminal before performing the work.
• Check that no brake fluid leakage is present after replacing
the parts.
• Burnish the brake contact surfaces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage. Refer to
BR-79, "BRAKE PAD : Inspection
(front brake pad),
BR-82, "BRAKE CALIPER ASSEMBLY : Inspection and Adjust-
BR-85, "BRAKE PAD : Inspection and Adjustment"
(rear brake pad),
"BRAKE CALIPER ASSEMBLY : Inspection and Adjustment"
(rear disc rotor).
