PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" ELS0011T

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:
q 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.
q 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.
q 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 ELS000L3

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.
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 If the vehicle pulls to either side while driving on a straight and level road, or if
balance you detect uneven or abnormal tire wear, there may be a need for wheel align-
MA-22, FSU-5
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel
balancing may be needed.
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
Check for cracks or wear if they do not wipe properly. --
blades
Doors and engine Check that all doors and the engine hood operate smoothly as well as the trunk
hood 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
MA-26
when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently.
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.

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
Warning lamps and
Make sure that all warning lamps and chimes are operating properly. --
chimes
Windshield wiper and Check that the wipers and washer operate properly and that the wipers do not
--
washer 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 MA-27
belt webbing for cuts, fraying, wear or damage.
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.

Engine coolant level Check the coolant level when the engine is cold. MA-12
F
Radiator and hoses Check the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the hoses have no cracks, deformation, --
deterioration or loose connections.
Brake fluid level Make sure that the brake fluid level is between the "MAX" and "MIN" lines on the G
MA-23
reservoir.
Battery Check the fluid level in each cell. It should be between the "MAX" and "MIN"
lines. Vehicles operated in high temperatures or under severe conditions require -- H
frequent checks of the battery fluid level.

MA-25
level and lines attachment, leaks, cracks, etc. J
Exhaust system Make sure there are no loose supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of exhaust fumes, immediately locate MA-19
the trouble and correct it.
K
Underbody The underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around
-- MA
the exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate.
Fluid leaks Check under the vehicle for fuel, oil, water or other fluid leaks after the vehicle M
has been parked for a while. Water dripping from the air conditioner after use is
--
normal. If you should notice any leaks or gasoline fumes are evident, check for
the cause and correct it immediately.
