PRECAUTIONS

PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT 
BELT PRE-TENSIONER”

NLS0003G

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 and SB section of this Service Man-
ual.

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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

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
harness connectors.

GENERAL MAINTENANCE

GENERAL MAINTENANCE

PFP:00000

Explanation of General Maintenance

NLS0003J

General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform
checks and inspections themselves or have their INFINITI dealers do them.

OUTSIDE THE VEHICLE

The maintenance items listed here should be performed from time to time, unless otherwise specified.

INSIDE THE VEHICLE

The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.

Item

Reference page

Tires

Check the pressure with a gauge, including the spare, at least once a month 
and always prior to a long distance trips. Adjust to the specified pressure if nec-
essary. Check carefully for damage, cuts or excessive wear.

Wheel nuts

When checking the tires, make sure no nuts are missing, and check for any 
loose nuts. Tighten if necessary.

Tire rotation

Tires should be rotated every 12,000 km (7,500 miles).

MA-23

Wheel alignment and 
balance

If the vehicle pulls to either side while driving on a straight and level road, or if 
you detect uneven or abnormal tire wear, there may be a need for wheel align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel 
balancing may be needed.

MA-22

FSU-5

  ,

RSU-5

Windshield

Clean the windshield on a regular basis.
Check the windshield at least every six months for cracks or other damage. 
Repair as necessary.

Windshield wiper 
blades

Check for cracks or wear if they do not wipe properly.

Doors and engine 
hood

Check that all doors and the engine hood operate smoothly as well as the trunk 
lid and back hatch. Also make sure that all latches lock securely. Lubricate if 
necessary. Make sure that the secondary latch keeps the hood from opening 
when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently.

MA-26

Lamps

Make sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and 
other lamps are all operating properly and installed securely. Also check head-
lamp aim. Clean the headlamps on a regular basis.

Item

Reference page

Warning lamps and 
chimes

Make sure that all warning lamps and chimes are operating properly.

Windshield wiper and 
washer

Check that the wipers and washer operate properly and that the wipers do not 
streak.

Windshield defroster

Check that the air comes out of the defroster outlets properly and in sufficient 
quantity when operating the heater or air conditioner.

Steering wheel

Check that it has the specified play. Be sure to check for changes in the steering 
condition, such as excessive play, hard steering or strange noises.
 Free play: Less than 35 mm (1.38 in)

Seats

Check seat position controls such as seat adjusters, seatback recliner, etc. to 
make sure they operate smoothly and that all latches lock securely in every 
position. Check that the head restrains move up and down smoothly and that 
the locks (if equipped) hold securely in all latched positions. Check that the 
latches lock securely for folding-down rear seatbacks.

Seat belts

Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters and 
retractors) operate properly and smoothly, and are installed securely. Check the 
belt webbing for cuts, fraying, wear or damage.

MA-27

Accelerator pedal

Check the pedal for smooth operation and make sure the pedal does not catch 
or require uneven effort. Keep the floor mats away from the pedal.
