Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006598731
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.
The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.
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 the “SRS AIR BAG”.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
• The vehicle may be equipped with a passenger air bag deactivation switch which can be operated by
the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled and
will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled and
could inflate for certain types of collision. After SRS maintenance or repair, make sure the passenger
air bag deactivation switch is in the same position (ON or OFF) as when the vehicle arrived for ser-
vice.
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, DO NOT 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:0000000006598732
NOTE:
• Before removing and installing any control units, first turn the ignition switch to the LOCK position, then dis-
connect both battery cables.
• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
• Always use CONSULT-III 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.

Precaution for Procedure without Cowl Top Cover
INFOID:0000000006598733
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake System
INFOID:0000000006383041
WARNING:
Clean any dust from the front brake and rear brake using a vacuum dust collector. Never blow by com-
pressed air.
• Brake fluid use refer to
MA-13, "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 confirm the specified tightening torque when installing the brake pipes.
• After pressing the brake pedal more deeply or harder than normal driving, such as air bleeding, check each
item of brake pedal. Adjust brake pedal if it is outside the standard value.
• 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 a flare
nut torque wrench (A).
• Turn the ignition switch OFF and disconnect the ABS actuator and
electric unit (control unit) harness connector or the battery negative
terminal before performing the work.
• Check that no brake fluid leakage is present after replacing the
parts.
Precaution for Brake Control system
INFOID:0000000006383042
• Always perform a pre-driving check to drive the vehicle.
• Always check speed and safety while driving the vehicle.

PRECAUTIONS
• To operate CONSULT-III while driving, more than one person is required to be in the vehicle to avoid interfer-
ence to driving and ensure safety.
• Slight vibrations are felt on the brake pedal and the operation noises occur, when ABS function or EBD func-
tion operates. This is not a malfunction because it is caused by ABS function or EBD function that is nor-
mally operated.
• When starting engine or when starting vehicle just after starting engine, brake pedal may vibrate or motor
operating noise may be heard from engine compartment. This is normal condition.
• Brake stopping distance may become longer than models without ABS function depending on the road con-
ditions, when ABS function is operated on slippery road like rough road, gravel road or snowy road.
• When a malfunction is indicated, always collect information from the customer about conditions of occur-
rence, estimate cause and perform operation. Check brake booster operation, brake fluid level and brake
fluid leakage, as well as electrical system.
• The optimum performance is achieved by control for ABS function or EBD function when all of brakes, sus-
pensions and tires installed on the vehicle are the specified size and parts. Brake performance and control-
lability may be negatively affected when other parts than the specified are installed.
• Brake stopping distance may become longer and steering stability may be negatively affected, when tires in
different size and combination or other parts than the specified are used.
• When a radio (including wiring), antenna and antenna lead line are located near ABS actuator and electric
unit (control unit), a malfunction or improper operation may occur for the control of ABS function or EBD
function.
• When the following items are replaced by other parts than genuine parts or modified, ABS warning lamp and
brake warning lamp may turn ON, and the control may not operate normally for ABS function or EBD func-
tion.
- Suspension component parts (shock absorber, spring, bushing and others)
- Tire and wheel (other than the specified size)
- Brake component parts (brake pad, disc rotor, brake caliper and others)
- Engine component parts (ECM, muffler and others)
- Body reinforcement component parts (rollover bar, tower bar and others)
• When suspension, tire and brake component parts are excessively worn or deteriorated and the vehicle is
driven, ABS warning lamp and brake warning lamp may turn ON, and the control may not operate normally
for ABS function or EBD function.
• ABS warning lamp and brake warning lamp may turn ON, when only front wheel or rear wheel is rotated
using a free roller. This is not a malfunction, because it is caused by wheel speed difference between wheel
that is rotated and wheel that is not rotated. In this case, perform self-diagnosis, check self-diagnosis results,
and erase memory.
• When power supply voltage is not normal, ABS warning lamp and brake warning lamp turn ON. ABS actua-
tor and electric unit (control unit) stops control for ABS function or EBD function. Ordinary brake operates.
After power supply returns to normal, ABS warning lamp and brake warning lamp turn OFF. The control
becomes operative for ABS function or EBD function.
