EXTERIOR LAMP BATTERY SAVER CONTROL
When the lighting switch is in the 1ST or 2ND position (or if auto light system is activated), and ignition switch
is turned from ON or ACC to OFF, battery saver control function is activated.
Under this condition, illumination lamps remain illuminated for 5 minutes, then illumination lamps are turned
off.
When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after
illumination lamps are turned off by battery saver control, and illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

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
necessary. 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 replacement by reaching wear limit of tire. WT-11
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-33
,
FSU-6
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. Lubri-
cate 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-38
Lamps

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 steer-
ing 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. —

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 reservoir. MA-35
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 frequent checks of the battery fluid level. SC-6, "

Engine drive belts
Make sure that no belt is frayed, worn, cracked or oily. MA-14, MA-22
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-18,
MA-25
Power steering fluid
level and lines Check the level on the dipstick with the engine off. Check the lines for improper
attachment, leaks, cracks, etc. MA-37
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 the trouble and correct it. MA-29
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. —

ENGINE MAINTENANCE (VQ35DE ENGINE)
Revision: 2006 July 2007 FX35/FX45
ENGINE MAINTENANCE (VQ35DE ENGINE)PFP:10001
Checking Drive BeltsNLS00063
WARNING:
Be sure to perform when engine is stopped.
1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection or tension at a point on belt midway between pulleys.
Inspection should be done only when engine is cold, or over
30 minutes after engine is stopped.
Measure the belt tension with belt tension gauge (Commercial
service tool: BT3373-F or equivalent) at points marked
shown in the figure.
When measuring the deflection, apply 98 N (10 kg, 22 lb) at
the marked point.
Adjust if the belt deflection exceeds the limit or if the belt ten-
sion is not within specifications.
CAUTION:
When checking the belt deflection or the tension immediately after installation, first adjust it to
the specified value. Then, after turning crankshaft two turns or more, re-adjust to the specified
value to avoid variation in deflection between pulleys.
Tighten idler pulley lock nut by hand and measure the deflection or the tension without loose-
ness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on belt.
Drive Belts Tension AdjustmentNLS00064
CAUTION:
When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.
When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-
ment”.
When checking belt deflection or tension immediately after installation, first adjust it to the speci-
fied value. Then, after turning crankshaft two turns or more, re-adjust to the specified value to
avoid variation in deflection between pulleys.
When installing belt, make sure that it is correctly engaged with pulley grooves.
Keep engine oil, working fluid and engine coolant away from belt and pulley grooves.
Do not twist or bend belt excessively.

Checking Power Steering Fluid and LinesNLS00070
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80 °C (122 to 176 °F)
or “COLD” range at fluid temperatures of 0 to 30 °C (32 to 86 °F).
CAUTION:
Do not overfill.
Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS"
Check lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.
Check rack boots for accumulation of power steering fluid.
Axle and Suspension PartsNLS00071
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.
Shake each wheel to check for excessive play.
Check wheel bearings for smooth operation.
Check axle and suspension nuts and bolts for looseness.
Check strut (shock absorber) for oil leakage or other damage.
Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.

Fuse NKS003G8
If fuse is blown, be sure to eliminate cause of malfunction before
installing new fuse.
Use fuse of specified rating. Never use fuse of more than speci-
fied rating.
Do not partially install fuse; always insert it into fuse holder prop-
erly.
Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible LinkNKS003G9
A melted fusible link can be detected either by visual inspection or by
feeling with finger tip. If its condition is questionable, use circuit
tester or test lamp.
CAUTION:
If fusible link should melt, it is possible that critical circuit
(power supply or large current carrying circuit) is shorted.
In such a case, carefully check and eliminate cause of mal-
function.
Never wrap outside of fusible link with vinyl tape. Important:
Never let fusible link touch any other wiring harness, vinyl
or rubber parts.
Circuit Breaker NKS003GA
The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.
