General MaintenanceELS000AL
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 the
checks and inspections themselves or they can have their NISSAN dealers do them for a nominal charge.
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.
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.Item Reference page
TiresCheck the pressure with a gauge periodically when at a service station, includ-
ing the spare, and adjust to the specified pressure if necessary. Check carefully
for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors, the engine hood, the trunk lid and back door operate prop-
erly. Also ensure 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
lubrication frequently.BL-4
,BL-8
Tire rotationTires should be rotated every 5,000 km (3,000 miles).MA-38
Item Reference page
LampsMake 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.—
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating properly. —
Steering wheelCheck that it has the specified play.
Check for changes in the steering conditions, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
Seat beltsCheck 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-3

Fluids and LubricantsELS000C8
*1: For further details, see “SAE Viscosity Number”.
*2: Never use API CG-4.
*3: Use Genuine Nissan Anti-freeze Coolant (L2N)] or equivalent in its quality, in order to avoid possible aluminum corrosion within the
engine cooling system caused by the use of non-genuine engine coolant.
Note that any repairs for the incidents within the engine cooling system while using non-genuine engine coolant may not be
covered by the warranty even if such incidents occurred during the warranty period.
*4: Contact a Nissan dealership for more information regarding suitable fluids, including recommended brand(s) of Dexron

2. Open drain plugs on cylinder block.
3. Remove reservoir tank and drain coolant.
4. Check drained coolant for contaminants such as rust, corrosion
or discoloration.
If contaminated, flush engine cooling system. Refer toMA-21,
"FLUSHING COOLING SYSTEM".
REFILLING ENGINE COOLANT
1. Install reservoir tank, radiator drain plug and cylinder block drain plug.
Apply sealant to the thread of cylinder block drain plug.
lUse Genuine Liquid Gasket or equivalent.
2. Fill radiator and reservoir tank to specified level.
lUse genuine Nissan anti-freeze coolant or equivalent mixed
with water (distilled or demineralized).
Refer toMA-17, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS".
lPour coolant slowly of less than 2 (2-1/8US qt,1-3/4 lmp
qt) a minute to allow air in system to escape.
3. Warm up engine to normal operating temperature without radia-
tor cap installed.
lIf coolant overflows radiator filler hole, install filler cap.
4. Run engine at 3,000 rpm for 10 seconds and return to idle speed
with radiator cap installed.
lRepeat two or three times.
Watch coolant temperature gauge so as not to overheat the engine.
5. Stop engine and cool down to less than approximately 50°C(122°F).
lCool down using a fan to reduce the time.
lIf necessary, refill radiator up to filler neck with coolant.
6. Refill reservoir tank to MAX level line with coolant.
7. Repeat steps 5 through 7 two or more times with radiator cap installed until coolant level no longer drops.
8. Check cooling system for leaks with engine running.
9. Warm up engine, and check for sound of coolant flow while running engine from idle up to 3,000 rpm with
heater temperature controller set at several position between COOL and WARM.
lSound may be noticeable at heater unit.
10. If sound is heard, bleed air from cooling system by repeating steps 5 through 7 until coolant level no
longer drops.
lClean excess coolant from engine.

Checking Drive BeltsEL S00 0C C
lBefore inspecting the engine, make sure the engine has cooled
down; wait approximately 30 minutes after the engine has been
stopped.
lVisually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.
lWhen measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point ( ).
CAUTION:
lWhen checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turn-
ing the crankshaft two turns or more, re-adjust to the
specified value to avoid variation in deflection between
pulleys.
lTighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Changing Engine CoolantEL S00 0C D
WA RN ING:
lTo avoid being scalded, never change the coolant when the engine is hot.
lWrap a thick cloth around cap and carefully remove the cap. First, turn the cap a quarter of a turn
to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
1. Open radiator drain plug at the bottom of radiator, and remove
radiator cap.
lBe careful not to allow coolant to contact drive belts.
lCover the exhaust tube heat shield to prevent from splashing
coolant.
2. Remove reservoir tank, drain coolant, then clean reservoir tank.
3. Open drain plugs on cylinder block and air relief plug.
4. Check drained coolant for contaminants such as rust, corrosion
or discoloration.
If contaminated, flush engine cooling system. Refer toMA-29,
"FLUSHING COOLING SYSTEM".
