GENERALMAINTENANCE

General maintenance includesthoseitemswhich should bechecked duringthenormal day-to-day
operation ofthe vehicle. Theyareessential ifthe vehicle isto continue operating properly.Theowners
can perform thechecks andinspections themselves orthey canhave theirNISSAN dealersdothem.

Item

OUTSIDE THEVEHICLE

The maintenance itemslistedhereshould beperformed fromtimetotime, unless oth-
erwise specified.

Tires
Check thepressure withagauge periodically whenataservice station, including
the spare, andadjust tothe specified pressureifnecessary. Checkcarefully fordamage,
cuts orexcessive wear.

Windshield wiperblades
Checkforcracks orwear ifthey donot wipe properly.

Doors andengine hood
Check thatalldoors, theengine hood,thetrunk lidand back
door operate properly. Alsoensure thatalllatches locksecurely. Lubricate hinges,
latches, rollersandlinks ifnecessary. Makesurethatthesecondary latchkeeps thehood
from opening whentheprimary latchisreleased.
When driving inareas usingroadsaltorother corrosive materials, checkforlubrication
frequently.

Tire rotation
Tiresshould berotated every
10,000
km
(6,000
miles).

INSIDE THEVEHICLE

The maintenance itemslistedhereshould bechecked onaregular basis,suchaswhen
performing periodicmaintenance, cleaningthevehicle, etc.

Lights
Makesurethattheheadlights, stoplights, taillights, turnsignal lights,andother
lights arealloperating properlyandinstalled securely. Alsocheck headlight aim.

Warning lightsandbuzzers/chimes
Makesurethatallwarning lightsandbuzzers/chimes
are operating properly.

Steering wheel
Check forchange inthe steering conditions, suchasexcessive freeplay,
hard steering orstrange noises.

Free play: Lessthan35mm (1.38 in)
Seat belts
Check thatallparts ofthe seat beltsystem (e.g.buckles, anchors, adjusters
and retractors) operateproperly andsmoothly, andareinstalled securely. Checkthebelt
webbing forcuts, fraying, wearordamage.

UNDER THEHOOD ANDVEHICLE

The maintenance itemslisted hereshould bechecked periodically e.g.each timeyou
check theengine oilorrefuel.

Windshield washerfluid
Check thatthere isadequate fluidinthe tank.

Engine coolant level
Check thecoolant levelwhen theengine iscold.

Engine oillevel
Check thelevel afterparking thevehicle onalevel spotandturning off
the engine.

Brake andclutch fluidlevels
Makesurethatthebrake andclutch fluidlevels arebetween
the "MAX" and"MIN" linesonthe reservoir.

Battery
Checkthefluid level ineach cell.Itshould bebetween the"MAX" and"MIN"
lines.
