PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951663
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 three mi nutes before performing any service.

GENERAL MAINTENANCE
FOR USA AND CANADA
FOR USA AND CANADA : Explana
tion of General MaintenanceINFOID:0000000009464530
General maintenance includes those items which shoul d 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 NISSAN 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 often and always prior to long distance trips.
Adjust the pressure in all tires, including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive wear. MA-39
Wheel nuts
When checking the tires, make sure no nuts are missing, and check for any loose
nuts. Tighten if necessary. MA-39
Tire rotation
Tires should be rotated every 5,000 miles (8,000 km). MA-39
Tire Pressure Monitor-
ing System (TPMS)
transmitter compo-
nents Replace the TPMS transmitter grommet seal, valve core and cap when the tires
are replaced due to wear or age. WT-57
Wheel alignment and
balance If the vehicle should pull 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
alignment. If the steering wheel or seat vibrates at normal highway speeds,
wheel balancing may be needed. For additional information regarding tires, refer
to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada)
in the NISSAN Warranty Information Booklet. FSU-25
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 properly. 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 for lu-
brication frequently. MA-45, "LOCKS, HING-
ES AND HOOD LATCH :
Lubricating"
Lamps
Make sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and oth-
er lamps are all operating properly and installed securely. Also check headlamp
aim. Clean the headlamps on a regular basis. EXL-122
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. 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) —

< PERIODIC MAINTENANCE >
GENERAL MAINTENANCE
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel).
SeatsCheck seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every po-
sition. 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. SB-5, "Inspection"
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. —
Brakes Check that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
booster Check the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to keep
the floor mats away from the pedal. BR-48
,
BR-49
Parking brake Check that the pedal has the proper travel and make sure that the vehicle is held
securely on a fairly steep hill when only the parking brake is applied. PB-4
CVT P (Park) position
mechanism On a fairly steep hill check that the vehicle is held securely with the shift selector
in the P (Park) position without applying any brakes. —
Item

ItemReference page
Windshield washer
fluid Check that there is adequate fluid in the tank. —
Engine coolant level Check the coolant level when the engine is cold. MA-14
(QR25DE)
MA-23
(VQ35DE)
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, de-
terioration or loose connections. —
Brake and clutch fluid
levels Make sure that the brake and clutch fluid levels are between the “MAX” and “MIN”
lines on the reservoir. MA-41
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 fre-
quent checks of the battery fluid level. —
Engine drive belts Make sure that no belt is frayed, worn, cracked or oily. MA-13
(QR25DE)
MA-22
(VQ35DE)
Engine oil level Check the level on the oil level gauge after parking the vehicle on a level spot and
turning off the engine. MA-17
(QR25DE)
MA-26
(VQ35DE)
Power steering fluid
level and lines Check the level when the fluid is cold, with the engine off. Check the lines for im-
proper attachment, leaks, cracks, etc. MA-44
Exhaust system
Make sure there are no loose supports, cracks or holes. If the sound of the ex-
haust seems unusual or there is a smell of exhaust fumes, immediately locate the
trouble and correct it. MA-31
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 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
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. —
